2 Study on Geometric calibration of UAV   Small-Format Photogrammetry- Nan Kang Calibration Site as an example Unmanned aerial   vehicle (UAV) has been rapidly developing in the world of photogrammetry and   remote sensing. Aerial photogrammetry by using small-format aerial   photographic system and UAV is both lower height ( less than 500 m) and   low-cost. However, to ensure the quality of surveying and mapping, the   signalized geometric targets of Nan-Gang calibration site have set to be   observed by the Global Navigation Satellite System (GNSS) receivers. The 3D   coordinates (Nr, Er, hr) of them are calculated by the rigorous adjustment as   the reference values for calibration. Then, implementation of UAV and   small-format aerial photometric system is in accordance with the calibration   procedure to obtain the 3D coordinates (Nm, Em, Hm) as the measured   values.
   
    The classical digital aerial photogrammetry method is supplemented with the   image dense matching software processing using the technology of computer   vision in recent years. The differences of 3 D coordinates of signalized   geometric targets are evaluated by aerial triangulation, and the root mean   square error (RMSE) is analyzed too. The uncertainties are also discussed in   this paper.

3 Squareness Evaluation of Three-Axis   Machines by Using Laser Ranging Principle Machine tools and   coordinate metrology machines are commonly constructed by three linear   slides. Even though the five-axis machine tools which add the two additional   rotational motors, the performance of machine tools is still closely related   to the structure of three linear slides. Therefore, this research is focusing   on evaluating the performance of three-axis structure by using laser ranging   instruments. First, the analysis is carried out by comparing the measured   results with the commands of the controller. Further, the squareness of the   machine is calculated by the proposed method. In the future, the presented   method will be applied to compensate the machines in order to enhance the   positioning accuracy. 運輸與能源計量研討會 20171215

9 Research on verification technology of   Seismograph The application scope   of seismograph is increasing, including the elevated road, railway safety,   intelligent building, soil slope monitoring, earthquake early warning, Pier   tilt and water level changes, such sensors shoulder long-term monitoring of   the responsibility, so for weathering, waterproof, anti-jamming and other   design requirements are very high, coupled with their own high cost,   replacement costs are expensive, Poor use of environmental conditions,   physical characteristics are susceptible to change, so only accurate   verification techniques can ensure the reliability of their physical   properties; At present, due to less research and manufacture of earthquake   sensor manufacturers, most of the seismic sensors are European, American and   Japanese direct imports, therefore, seismograph-related specification   verification technology, It is still relying on the foreign parent company to   provide relevant certification of technical assistance [1], the author has   been in contact with different types of seismograph to detect related   problems, so the most widely used verification technique of the force balance   seismograph sensor is explained by the frequency response, full scale range,   sensitivity, dynamic range, The characteristics of linearity and transverse   sensitivity are introduced, and the related physical properties and   verification methods are discussed. 三聯技術雜誌 20171201
10 Development of law wind speed   micro-scale anemometer This study designed a   paddle-type micro-cantilever beam structure and its upper layer has a   platinum resistors. When any force is applied to the cantilever structure, it   will be deformed, and the resistance of the platinum resistors on the   structure changes. Using this principle, we designed a low wind speed   micro-scale anemometer with a target wind speed range of 0 m/s to 1 m/s and a   resolution of 0.01 m/s.

11 Electromagnetic Field Strength   Measurement and uncertainty analysis Follow the renewed   EMS standards, the electromagnetic field strength measurement system of   national measurement laboratory had been updated calibration capability to   200 V/m step by step to satisfy traceability of measurement since 2016.

12 Calibration and Testing of a Heat Pipe   Probe for a Hand-Held Measuring Apparatus of Thermal Conductivity The traditional   thermal probe method is suitable for measuring the thermal conductivity of   geological soil materials, plastics, and other soft materials, but it is   still limited by length-to-diameter ratio of a needle structure for meeting   the assumptions of the transient hot wire method. However, such a structure   often results in a weak mechanical probe. When it is inserted into a solid   material that is harder than expected, it may be bended or damaged to   influence its accuracy and applicability.
   
    In order to expand the applicability for unknown geological and plastic   materials, it is necessary to enhance the geometry of a thermal needle probe.   This requirement can lead to a design which differs substantially from the   ideal assumptions. For this reason, it should be corrected by taking in the   calibration and data analysis. The purpose of this study was to develop a   heat pipe probe technology with high thermal conductivity and mechanically   strength. The heat pipe probe has a diameter of 4 mm and a total length of   120 mm. It is made by a steel container, a heat pipe, a thermocouple, a   heating wire, and less infilled materials of high thermal conductivity. The   calibration curve of a heat pipe probe can be obtained by establishing the   calibration process used a modified transient plane source method, and it is   suitable for standard measurements in the range 0.033 W/(m·K) to 1.340   W/(m·K), to meet the commonly used solid materials at the current stage.

13 Three Degrees-of-Freedom Optical   Spindle Error Motion Measurement Device An inexpensive   optical measurement device for spindle error measurement, which has three   degrees of freedom (3DOF) and is integrated with the Internet of things   (IoT), is presented. The device uses an artificial standard sphere, which is   set on the spindle to be measured, and two optical measurement modules. Each   module includes an aspherical lens, a laser diode, a beam splitter and a   quadrant position-sensing detector, and the autocollimator principle of   measurement is used. After the calibration of the device, the residual error   and resolution are about 1 and 0.1 μm, respectively. The experiment results   show errors of measurement, caused by the roughness of the standard sphere,   as periodic noise with an amplitude of 10 μm. After the noise has been eliminated,   the error motion of the spindle, which includes radial, axial, and   synchronous and asynchronous errors, can be observed. The proposed device can   also be used for the measurement of spindle thermal expansion. Sensors and Materials 20171124
14 Fused-Quartz Micro-Resonator Based   Passive Mode-Locked Fiber Laser for Optical Communications We demonstrate a   compact and portable 84 GHz passive mode-locked fiber laser, in which a   dual-fiber coupled fused-quartz micro-resonator is employed as the   intra-cavity optical comb filter as well as the optical nonlinear material   for optical frequency comb generation. Eight coherent optical tones can be   generated in the proposed fiber laser. The 20-dB bandwidth of the proposed   fiber laser is larger than 588 GHz, and the full-width half-maximum (FWHM)   pulse-width is 2.5 ps. The generated mode-locked signals were then utilized   to carry a 5-Gbit/s on-off-keying (OOK) signal and transmitted over a 20-km   standard single mode fiber (SMF). The experimental results fulfilled the 7 %   forward error correction (FEC) requirement, implying the proposed fiber laser   can serve as a potential light source for fiber-wireless applications. 光電與通訊工程應用研討會 20171124
15 OPTICAL FABRY-PEROT INTERFEROMETER FOR   GAS REFRACTIVE INDEX AND ABSOLUTE GAS PRESSURE MEASUREMENT Pressure is a   quantity describing the amount of force applied on a surface of an object per   unit area.  For gas pressure, this   force actually originates from collisions between randomly moving molecules   of the gas and the surface of an object. According to the kinetic theory of   gases and the ideal gas law, the pressure is a function of gas density rho   and temperature T, namely p = rho kB T, where kB is the Boltzmann   constant.  Therefore, the gas pressure   p can be obtained by measuring the gas density rho and the temperature. This   paper introduces the design and fabrication of an optical refractometer based   on Fabry-Perot interferometers (FPIs) for measuring the refractive index of   the gas, a project launched in this year. In the design, two lasers will be   independently frequency locked to two FPIs using Pound-Drever-Hall technique.   One FPI is in vacuum which serves as an optical frequency reference and the   other one is immersed in the gas. The refractive index of gas can be obtained   by comparing the frequencies of two lasers. This is the basic principle of   this instrument. Currently, the two FPI cavities were fabricated out from a   block of ULE glass to reduce length variations from temperature fluctuations.   Surfaces polishing and mirrors bonding are underway.  More tests will be done after the assembly   of the FPI and preliminary results will be presented in the symposium.

16 Design and Development of the   Step-gauge Calibration System A step-gauge,   consisting of many short gauge blocks fixed on a base, is widely used in the   calibration of machine tools and coordinate measuring machines (CMMs). The   step-gauge calibration system is developed by comprising a laser   interferometer and a CMM, the interferometer used as the standard for   traceability of length measurement and designed as two-path interferometer   system to eliminate the Abbe error, and then integrated with the   high-precision CMM, consisting of the moving platform and probing system to   implement the calibration procedure for step gauge.

17 Analysis of trace element impurity in   special gases by spICP-MS coupled with gas exchange technique Special gases, such   as ammonia, nitrogen fluoride, and tetrafluoromethane, are widely used in   semiconductor processing. Trace particle impurities in the gases used in   silicon-based processes can cause effect such as resist pattern failures,   resistivity shifts, diode leakage, junction leakage, lifetime degradation,   and result in reduction of products yield. The demand for high purity gases   in semiconductor industry is increasing dramatically. Impinger is a commonly   collector used to trap and pre-concentrate the particulates from the cylinder   and then analyze with ICP-MS. However, collection efficiency was found to be   less than 20% for particles with a diameter less than micrometer1. Some gases   such as NH3 would dissolved in water during collection, however, the   saturated NH4OH solution can precipitate particles and extinguish the plasma.   Moreover, large sampling volume and dilution process during analysis will   result in higher detection limit.
   
   
   
    The technique of single particles inductively coupled plasma mass   spectrometry (spICP-MS) was recently applied to nanoparticle analysis and   numerous studies have established a set of metrological criteria of spICP-MS   for sizing or quantifying various types of nanoparticles. In this study,   spICP-MS was used to directly analyze metallic particulate from cylinder gas.   To prevent the plasma quenching, a gas exchange device (GED)2 was applied to   remove the gas matrix. After the gas exchange efficiency was optimized, the   composition of particulate impurity from ammonia gas was investigated. The   detection limit of this method is at least 100-fold lower than conventional   impinger method, and could be applied to online monitoring of the particulate   contaminants from the delivered gases without much consumption of cylinder   gas.

18 The Development of Thin Film Thickness   Measurement System by Using Soft X-Ray Reflectivity Technology With the next   technology node coming, accurate and reliable monitoring of different thin   film thickness is critical to quality of the chips in the advanced   microelectronic devices. In semiconductor industrial, the high-k/metal gate   thickness will be reduced to several nanometers for improved performance, and   the measured area will also be confine to several micrometers. However, the   optical measurement can no longer provide sufficient resolution and measured   area. A soft X-ray reflectivity was developed to monitor the film thickness   for the production of nanoscale thin films. The Annual Conference   on Engineering and Applied Science 20171107
19 A brief description of absolute   radiation thermometer Based on the   successful development of absolute temperature radiometers, accurate   measurement of extremely small heat and light radiation is achieved,   resulting in a revolutionary change and progress in temperature and light.

20 A Study of Phase Error Calibration   Technique for Current Shunts Using an AC Programmable Josephson Voltage   Standard AC Programmable   Josephson Voltage Standard (AC PJVS) system is the primary AC voltage   standard at National Measurement Laboratory (NML) in Taiwan. This AC PJVS   system can perform precision calibration of the AC voltage by using   differential sampling measurement technique. In addition, development of   power standard measurement technology based on AC PJVS is a currently   important research topic in the world's leading National Measurement   Institutes (NMIs). Therefore, NML had also carefully investigated the phase   error calibration technique for current shunts using an AC PJVS. We expected   this research could help to gradually complete the self-traceability of the   power standards in Taiwan. This paper describes the phase error calibration   technique and the uncertainty evaluation for current shunts using an AC PJVS   system. The measurement uncertainty of phase error for current shunts   calibrated by the AC PJVS is 0.80 mdeg in the input current range from 10 mA   to 80 A with the frequencies of 50 Hz and 62.5 Hz. 量測資訊雙月刊(量測中心) 20171101
21 NML's New AC Current Calibration   System Based on Ohm's Law NML established a new   AC current calibration system based on Ohm's Law in 2017, by using   low-inductance coaxial current shunts as standards. The calibration system   can provide calibration services for AC current sources , meters, and shunts.   Its measurement scope for AC current is 100 uA to 100 A @ 20 Hz to 10 kHz,   and the measurement uncertainties are (0.12 to 0.17) mA/A for current less   than 300 uA, and  (70 to 90) uA/A for   current greater than and equal to 300 uA.
   
    The new AC current calibration system based on Ohm's Law  was described, including its calibration   method, measurement uncertainty evaluation and measurement comformity   verification between the new system and the current system based on ac-dc   transfer technics.

23 The high precision compact laser   interferometer used in Rockwell Hardness Standards System in CMS 主要的洛氏硬度標準體係自1996年7月至1997年6月在測量標準中心建立。在此期間,光學標尺由一個激光干涉儀HP10737R三軸緊湊型乾涉儀代替。   當測量硬度時,用它來測量壓頭的深度和壓頭的俯仰和偏轉。 這些效應被表示為相應硬度的值。 當激光干涉儀測量硬度時測量壓頭的俯仰和偏航;   那麼我們可以通過俯仰和偏航測量來評估由阿貝誤差引起的硬度測量的不確定性。 然後我們可以通過這種測量來評估系統的惡化程度。   在本文中,我們將比較循環的結果來評估這幾年壓頭軸的老化效應 International   Multi-Conference on Engineering and Technology Innovation 20171029
24 The double balance lever of torque   standard machine with 5 kNm calibration capability in CMS The Primary In order   to improve the performance of torque standard machine, a good design and   manufacture of double-lever balance is essential, it was both to ensure   sufficient rigidity, but also to ensure there is enough sensitivity.   According to specifications, the initial load limit and the maximum load   limit of the sensitivity of not more than one of ten thousands. To this aim,   we apply knife and knife-seat is fulcrum of the double balance arm lever, and   on both sides of lever also use knife and knife-seat to connect left and   right dead weight groups.

25 Photoelectrochemical Biofuel Cells for   Electric Generation and Hydrogen Production The   photoelectrochemical electrodes have been studied for nearly thirty years,   where one of the earliest work was done by Honda and Fujishima which   describes the generation of electricity by photons or chemical reactions   inside the cells. They successfully used titanium oxide (TiO2) electrode to   decompose water with sunlight illumination and also considered introducing   the basic principles of manufacturing photoelectrochemical solar cells.   Different electrode materials were developed in the 1970s and 1980s, however,   the conversion efficiency of the solar cells using TiO2 is still low. In   2003, the research team of Garza uses combined dye-sensitized   photoelectrochemical cell (DSSCs) and fuel cells, creating a hybrid cell. The   working principle of the anode has the same role as a DSSC, where the cathode   is composed of a biofuel cell. They employed tin dioxide nanoparticles as the   anode electrode coated with porphyrin sensitizers. The key operation of the   hybrid cell is the electrons transfer process between the redox agents in the   anode and the sensitizers.The efficiency of the cell using tin dioxide as the   anode is still not high. In view of this, it is expected to use different   types of anode materials improving the efficiency of the electron conductivity   between the electrode, biological dyes and redox substances.

26 Advanced Technique for In-line   Measurement of Critical Dimension by Transmission Small Angle X-ray   Scattering Double grating   structures were measured by transmission small angle X-ray scattering (tSAXS)   measurement technique. The peak intensity variations of diffraction patterns   were analyzed and compared with the results from theoretical calculation. The   interaction terms from tSAXS measurement of double grationg structures   provide the ability to enhancement signals. Therefore, it can be used to   increase the diffraction intensity for solving the low efficiency problem of   critical dimension (CD) detection by present tSAXS machines. This technique   will be able to promote the development of next generation in-line CD   detection machine. International   Multi-Conference on Engineering and Technology Innovation 20171028
27 Compact 84 GHz Passive Mode-Locked   Fiber Laser Using Dual-Fiber Coupled Fused-Quartz Micro-Resonator We propose and   demonstrate a compact and portable-size 84 GHz passive mode-locked fiber   laser, in which a dual-fiber coupled fused-quartz micro-resonator is employed   as the intra-cavity optical comb filter as well as the optical nonlinear   material for optical frequency comb generation. About 8 coherent optical   tones can be generated in the proposed fiber laser. The 20-dB bandwidth is   larger than 588 GHz. The full-width half-maximum (FWHM) pulse-with of the   proposed laser is 2.5 ps. We also demonstrate the feasibility of using the   proposed passive mode-locked fiber laser to carry a 5-Gbit/s on-off-keying   (OOK) signal and transmit over 20 km standard single mode fiber (SMF). 7%   forward error correction (FEC) requirement can be achieved showing the proposed   fiber laser can be a potential candidate for fiber-wireless applications.

28 Soft X-Ray Reflectivity for Thin Film   Thickness Measurements Accurate  and    reliable  monitoring  of    different  thin  films    thickness  is  mandatory    to develop advanced microelectronic devices. We have developed a   thin-film metrology tool that fulfills    the  metrology  requirements  for    the  production  of    nanometers  film  technology.    The soft  x-ray  reflectivity  with    long  wavelength  source    measurement  was  designed    to  provide accurate, high   throughput, measurements. X-ray reflectivity is very sensitive to surface and   interface roughness, and also provides information about film density.   Improvements in the soft x-ray reflectivity configuration were made to allow   high throughput measurements on films as thin as 2 nm.  The long wavelength light source can   increase the incident angle during reflectivity measurement. As  soft    x-ray  reflectivity  already    used  anode  Al    source  under  grazing    incidence  and  the variation  of    the  angle  of    incidence,  a  θ-2θ    goniometer  was  simulated    by  combining  a photodiode and  a Silicon Drift  detector (SDD).  The photodiode is  used    to  reduce the high count-rate   of the direct and totally reflected beam at small angles, which exceeds the   working range  of  the SDD.    HfO2  layers  of    50  nm  were    characterized  using  this    new  setep.  The    performance  of  a    new in-line metrology tool in the future has been assessed.

29 Geometric Error Measurement of Machine   Tools Using Auto-Tracking Laser Interferometer Geometric error   measurement with traditional laser interferometers is generally a complex   process, especially for the measurement of squareness errors, which requires   a 90° Pentagon prism. For the development of the aviation industry, the size   and travel of a machine tool are becoming large and long. However, the setup   of optical alignment becomes difficult to deal with. An auto-tracking laser   interferometer (ATLI) is proposed in this paper for the squareness error   measurement of machine tools or coordinate-measuring machines (CMMs). The   procedure involves measurement of only one line of an axis, and the   measurement results can not only provide us the information with the   positioning errors but also with the squareness errors. This specially   designed interferometer instrument can help the industry to reduce the   working time of the machine tool assembly by approximately 50 %.

30 Displacement measurement simulation of   three-axis gantry type structure with auto-tracking ranging principle Machine tools and   coordinate measurement machines (CMM) are commonly constructed by three   linear kinetic chains. There are twenty-one terms of error motion for   three-axis structures. Among them linear positioning error has been generally   considered because it is convenient to be measured by means of a laser   interferometer. However, the squareness error becomes more significant when   machine stroke is increasing. The traditional method to evaluate squareness   using a laser interferometer is time-consuming and limited to specific   implements. The other measuring instrument like a LaserTRACER could be used   to measure robot arms, machine tools or CMM. This kind of auto-tracking   ranging system could also be used in squareness evaluation, and even in   geometric error evaluation.  In this   study, a single auto-tracking ranging system is simulated to measure a   virtual target. We built a kinetic model of gantry type structure machine   which included linear positioning and squareness error motion. Misalignment   error which is generated from multilateration method is also considered.   These simulation results could be compared with actual experiment data and   give scope for geometric error analysis of machine tools.

31 A Low Cost IoT Laser Interferometer by   Using Raspberry Pi3 Data transmission of   traditional laser interferometers in length measurement is usually through   USB and UART (Universal Asynchronous Receiver/Transmitter) interfaces. For   Industrial 4.0 needs, the length measurement data is collected by a master   computer through wireless interface. Thus, IoT (Internet of Things) technique   is employed for big data collection in recent years. An idea of laser   interferometer integrated to IoT technique is proposed in this study. First,   the interference signal is transformed into digital signal (i.e. A/B phase   signal) by a Schmitt trigger. And then the displacement is calculated by the   GPIO (General-purpose input/output) interfaces of the Raspberry Pi3. Finally,   the Raspberry Pi3 is connected to the master computer with a wireless device   like Wi-Fi (Wireless Fidelity), Bluetooth or ZigBee, and then the low cost   IoT laser interferometer is carried out. The    IoT Laser interferometer with low cost is designed for the error   motion measurement of large machine tools. The measured range can be reached   5 m and the resolution is about 0.1 m.

32 Reflective small angle electron   scattering to characterize nanostructures on opaque substrates Feature sizes in   integrated circuits (ICs) are often at the scale of 10?nm and are ever   shrinking. ICs appearing in today's computers and hand held devices are   perhaps the most prominent examples. These smaller feature sizes demand   equivalent advances in fast and accurate dimensional metrology for both   development and manufacturing. Techniques in use and continuing to be   developed include X-ray based techniques, optical scattering, and of course   the electron and scanning probe microscopy techniques. Each of these   techniques has their advantages and limitations. Here, the use of small angle   electron beam scattering measurements in a reflection mode (RSAES) to   characterize the dimensions and the shape of nanostructures on flat and   opaque substrates is demonstrated using both experimental and theoretical   evidence. In RSAES, focused electrons are scattered at angles smaller than   1°1°with the assistance of electron optics typically used in transmission   electron microscopy. A proof-of-concept experiment is combined with rigorous   electron reflection simulations to demonstrate the efficiency and accuracy of   RSAES as a method of non-destructive measurement of shapes of features less   than 10?nm in size on flat and opaque substrates.

34 Introduction to Development of a   Digital Diamond Detector In recent years about   the identification of diamonds, with the invention of Moissanite, there have   been more the domestic criminal records which jewelry stores were cheated by   using Moissanite. In that, the price of Moissanite is only one-tenth of that   of Diamond, the shape of Moissanite is almost the same as that of Diamond,   and  the testing results of a   traditional diamond detector between nature diamonds and Moissanites are the   same because the properties of Moissanite was not considered by the designers   of the diamond detector at that moment. The precision of a traditional   diamond detector is not good enough to identify the differences of the   thermal conductivity.
   
    In the light of this, this article will introduce the digital diamond   detector used with the thermal comparator method of thermal conductivity to   identify diamond and other diamond simulants. The digital diamond detector   can provide a consume environment and transaction demand with both   convenience and identifiability to jewelry stores.

35 Photometry Measurement for Curved   Surface Sources The development trend   for high-tech products is towards the capability of flexibility, for example   flexible lighting, display, and so on. The traditional photometry measurement   methods for flat and rigid products may not be applicable for flexible products.   Refining the measurement method to characterize the photometry

36 The Experimental Measurement and   Prediction on Wind Turbine Noise This paper presented   the noise survey and prediction of the wind turbine generator in compliance   with the IEC 61400-11, the NIEA P201.95C and ISO 9613 standards. The noise   levels were investigated for different measuring distances and different wind   turbine operating conditions under various wind speed conditions. The wind   turbine noise levels were shown with a strongly linear correlation to the   wind speeds at the rated power of 20% to 80%, while the noise levels are   almost maintained constant as the wind turbine had reached its maximum rated   power despite the wind speed was continuously rising. Measurement results   were compared to those of the predicted sound level calculated via the ISO   9613 standards. The higher the wind speed and the longer the propagation   distances caused the larger differences between the noise experimental survey   and numerical prediction results. This means that over a certain distance and   wind speed condition the wind turbine noise (event noise) could merge in the   wind noise (background noise).The overall results indicated that   meteorological factors influence the noise generated by the wind turbine   rather than the sound propagation.

37 The Comparison of Different Types of   Instruments on Nanoparticle Size Measurements through Interlaboratory   Comparisons There are several   techniques for measuring and characterizing the nanoparticle sizes. However,   these measurement results for same nanoparticles may deviate from each other   at an amount that is considered significant. To establish the effectiveness   and comparability of measurement methods on nanoparticles, the Center for   Measurement Standards of Industrial Technology Research Institute (CMS/ITRI)   conducted three interlaboratory comparisons on nanoparticle size measurements   in 2005, 2006 and 2012. In 2005, an APEC-led preliminary interlaboratory   comparison on nanoparticle size characterization was carried out among 10   laboratories from 6 economies. In 2006, the interlaboratory comparison was   carried out for the second time with a more focused objective of detailing   instrument-specific measurement instructions for enhancing the comparability   among different types of measurement methods. There were 16 laboratories from   10 economies participating in that comparison. In 2012, to harmonize the   measurement techniques and capabilities on nanoparticle size, an APMP   supplementary comparison was held among 14 national measurement laboratories.   In this paper, statistical analysis was carried out to identify that the   nanoparticle size measured from Dynamic Light Scattering (DLS) was generally   larger than the sizes measured from other measurement techniques including   Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM),   Atomic Force Microcopy (AFM), Differential Mobility Analyzer (DMA), and Small-Angle   X-ray Scattering (SAXS).

38 Calibration Capability Analysis for   Digital Pressure Gauge through Measurement Audits - the Alternative to   Proficiency Testing Under ISO/IEC 17025,   the laboratories are generally required to participate in interlaboratory   comparisons or proficiency testing to maintain their high competence and   assure the quality of results for establishing the effectiveness and   comparability of calibrations. Participation in proficiency testing to assure   the good performance and capabilities is the basic requirement for   laboratories in Taiwan to apply for accreditation certification or seek an   extension of the certification issued by Taiwan Accreditation Foundation   (TAF), the main accreditation body in Taiwan. When the proficiency testing is   not available, the calibration laboratories in Taiwan shall participate in   the measurement audits under the requirement of TAF. The Center for   Measurement Standards of Industrial Technology Research Institute (CMS/ITRI)   not only organize the proficiency testing programs regularly but also provide   the measurement audits to meet the needs of the calibration laboratories that   apply for the new accreditation items. In the last two years, the tests of   energy efficiency of compressed air systems were required by law, digital   pressure gauge calibration services are urgently demanded in industry. In   order to expand their measurement scopes to include the digital pressure   gauge calibration, 11 laboratories applied for measurement audits with the   CMS/ITRI since there was no proficiency testing program for digital pressure   gauge calibration. In these audits, the National Measurement Laboratory (NML)   provided the reference values for the digital pressure gauges. In this paper,   the results of interlaboratory comparisons for 11 laboratories were analyzed   based on the outcomes of the measurement audits. Through the statistical   analysis, the comparison results showed reasonable agreements in general   among the measurements on digital pressure gauge calibration for most of   calibration laboratories. It can also be found in this analysis that the   measurement audits can be used in confirming the competence of the laboratories   and provide solid proof for accreditation purpose.

39 Ontogenetic shift toward stronger,   tougher silk of a web-building, cave-dwelling spider Animal morphological   traits may vary across life stages. Web-building spiders are diverse   insectivores that can display ontogenetic shifts in the design and properties   of their webs. Nevertheless, we know little about how a critical component of   their webs, major ampullate silk (MAS), varies in property across life   stages, inferably owing to a difficulty in finding suitable model species.   The Tasmanian cave spider Hickmania troglodytes presents as a good model as   it is long-lived and grows to a large body size with overlapping generations.   We collected MAS from the webs of different-sized H. troglodytes and   performed tensile tests on MAS fibers collected from their webs to search for   shifts in properties over life stages. We found that strength and toughness   (i.e. ability to deform and absorb energy) of the MAS increased with spider   carapace width and body length. We expect that such a shift in silk   performance across life stages has distinctive advantages, including enhanced   prey capture capabilities, an improvement in the economy of silk production   and ability of the web to support the spider’s larger body.

40 USE MULTIPHYSICS SIMULATIONS AND   RESISTIVE PULSE SENSING TO STUDY THE EFFECT OF METAL AND NON-METAL   NANOPARTICLES IN DIFFERENT SALT CONCENTRATION Wafer fabrication is   a critical part of the semiconductor process when the finest linewidth with   the improvement of technology continues to decline. The nanoparticles   contained in the slurry or ultrapure water used for cleaning have a large   influence on the manufacturing process. Therefore, semiconductor industry is   hoping to find a viable method for on-line detection of the nanoparticles   size and concentration. Resistive pulse sensing technology is one of the   methods that may cover this question. There were a lot of reports showing   that nanoparticles properties of materials differ significantly from their   properties at nano length scales. So, we want to clear the translocation   dynamic and ion current changes in measurement of metal nanoparticles or non-metal   nanoparticles in different concentration electrolytes through the nanopore   when resistive pulse sensing technology has been used. In this study, we try   to use a finite element method that contains three governing equations to do   multiphysics coupling simulations. The Navier-Stokes equation describes the   laminar motion, the Nernst-Planck equation describes the ion transport, and   the Poisson equation describes the potential distribution in the flow   channel. Then, the reliability of the simulation results was verified by   resistive pulse sensing test. The existing results showed that the lower the   ion concentration the greater the effect of resistive pulse sensing was. We   investigated the effect of resistive pulse sensing on different materials by both   simulations and experiments. The results are discussed in this article.

41 d:x reflectance measurement for curved   surface with integrating sphere Ambient contrast   ratio (ACR) is a useful parameter to evaluate the quality of displays when   used under diffuse lighting conditions. The methodology recommended by most   documentary standards calculates  the  ACR    of  the  display    from  d:x  re?ectance.    Re?ectance  measurement  of ?at    surfaces typically  employs  an    integrating  sphere  and    a ?at  white  reference    plate.  However,  the    shape difference between the ?at white standard and test curved sample   causes changes to the amount of
   
    light  illuminating  their    surfaces  and  thus    gives  measurement  errors.    Especially  for  concave    test surfaces,  the  error    is  signi? cant  when    the  sample  has    small  radius  of    curvature.  To  increase    the measurement accuracy, this paper derives the correction factor to   compensate the effect caused by shape    difference  between  the    reference  plate  and    test  curved  sample.    The  associated  uncertainty
   
    analysis is also discussed in this paper.

42 Investigation on the Wind Turbine   Noise Measurement Results This paper shows the   wind turbine generator noise survey results from the IEC 61400-11 standards   and the NIEA P201.95C which is the environmental noise measurement procedure   hosted by Environmental Potection Agency, Taiwan. The noise propagation   characteristics and levels for the different measuring distances from wind   turbine under various wind speed conditions are illustrated. The wind turbine   generator noise levels are almost constant value, despite the continuously   raise of the wind speed' under the wind turbine satuated at maximun rated   power. within the rated power 20 % to 80 %, the noise levels shown the   strongly linear correlation to the wind speeds. Moreover, for strong wind   ondition, the wind turnine noise(event noise) will merge in the wind noise(background   noise). 應用聲學與振動學刊 20170801
43 CIPM Key Comparison of Air Speed, 0.5   m/s to 40 m/s The CCM.FF-K3.2011   comparison was organized for the purpose of determination of the degree of   equivalence of the national standards for air speed over the range 0.5 m/s to   40 m/s. An ultrasonic anemometer and a Laser Doppler anemometer were used as   transfer standards. Nine laboratories from three RMOs participated between   July 2013 and July 2015 – EURAMET: PTB, Germany; LNE-CETIAT, France; INRIM,   Italy; VSL, The Netherlands; E+E, Austria; SIM: NIST, USA; APMP: NMIJ/AIST,   Japan; NIM, China; CMS/ITRI, Chinese Taipei. The measurements were provided   at ambient conditions. All results of independent participants were used in   the determination of the key comparison reference value (KCRV) and the   uncertainty of the KCRV. The reference value was determined at each air speed   separately following “procedure A” presented by M.G. Cox [7]. The degree of   equivalence with the KCRV was calculated for each air speed and laboratory.   Almost all reported results were consistent with the KCRV. Metrologia 20170731
44 International Comparison   APMP.QM-S2.2015 Oxygen in nitrogen at 0.2 mol/mol A bilateral   comparison APMP.QM-S2 was done to show a competence in measurement and   calibration of oxygen in nitrogen. This comparison is a repeat of APMP.QM-S2   and is also designed to demostrate the capabilities of the participants.  The objective of this comparison is to   support and improve the CMCs of the participants.  This comparison was suggested and approved   in the meetings of APMP TCQM on November 2013 and CCQM GAWG on April   2014.
   
    This document describes the results of the supplementary comparison for   oxygen in nitrogen gas mixture.  The   nominal amount-of-substance fraction of oxygen is 0.20 mol/mol.

45 The application of ANOVA in Regression   Model of Metrology Regression analysis   and analysis of variance (ANOVA) are practical statistical methods. The   former is mainly used to estimate the relationship among variables and then   predict the unknown observations. In metrology, the calibration curve is an   application of regression analysis, which describes the relationship between   standard values and indications. The latter provides a statistical test of   whether the independent variables (factors) are significant or not, which is   based on the variations of the variances. The similarity between two   statistical methods is to understand how independent variables effect the   dependent variable.
   
    Based on the process of establishing the regression model, this paper   presents two different applications of ANOVA in metrology. One is to confirm   the fitness of the regression model, and the other is to evaluate the   measurement uncertainty of the predictions when repeated observations are   included.

46 On-site Evaluation of a Portable 100   GHz Microresonator-based Optical Frequency Comb Generation System A micro-comb   generation system was developed and verified to provide an array of   multi-wavelength laser sources at a remote site without environmental   control. The generated comb line frequencies coincide nicely with 100 GHz   DWDM channel frequencies, assuming the suggested channel bandwidth is 0.3 nm.   Quality of selected comb lines was evaluated by EVM measurements and RF   spectrum measurements. The measured EVM values are approaching typical EVM   values of less than 3 % in fiber optic communications. The generated 100 GHz   comb lines have reasonably good quality for DWDM and RoF applications. International   Frequency Control Symposium/European Frequency and Time Forum (IFCS/EFTF) 20170709
47 BI-LATERAL COMPARISON BETWEEN CMS AND   NIST FOR PRIMARY GAS FLOW STANDARDS A bi-lateral   comparison of the pressure, volume, temperature, and, time (PVTt) primary gas   flow standards at CMS/ITRI in Taiwan and NIST in the USA was conducted in   2015. Two critical flow venturis (CFVs) with nominal throat diameters of   1.699 mm and 0.296 mm were selected as transfer standards. The CFVs were   calibrated using the 30 L and the 500 L collection systems at CMS, and then   using NIST’s 34 L and 677 L collection systems. Both CFVs indicated agreement   between the NIST and CMS standards within uncertainty expectations. The   results for the smaller CFV showed differences of only 0.03 %, but the   differences from the larger CFV were as big as 0.15 %. Internal comparisons   between the different sized collection systems at CMS and NIST were conducted   and were both in agreement, indicating the larger differences measured with   the 1.699 mm CFV are caused by the transfer standard rather than the PVTt   systems. 量測資訊雙月刊(量測中心) 20170703
48 Analysis of the different assigned   value determination methods for proficiency testing - using gauge block   calibration as an example According to ISO/IEC   17043:2010, the definition of proficiency testing is evaluation of   participant performance against pre-established criteria by means of   interlaboratory comparisons. Thus pre-established criteria has significant   impact on the evaluation of participant performance, in which assigned value   attributed to a particular property of a proficiency test item and its   standard deviation for proficiency assessment played the key role in the   evaluation criteria. In addition, according to ISO/IEC 13528:2015, the   assigned value and its standard uncertainty can be determined according to   the type and purpose of the proficiency testing scheme. In order to explore   the impact of choosing different methods to determine the assigned value and   its expanded uncertainty for proficiency testing results, one gauge block   calibration proficiency testing was used as an example for discussion. 量測資訊雙月刊(量測中心) 20170703
49 Establishment of Purity Analysis   Method for Lead Metal Lead is currently   used in lead-acid batteries, semiconductor industry, pipeline and radiation   protection purposes, and lead purity will directly affect the quality of   product production, so the need to establish lead metal purity analysis   method. The inductively coupled plasma mass spectrometer is widely used in   the measurement of ultra trace metal impurity due to its high sensitivity,   rapid and low dosage.

50 Final report of the key comparison of   APMP.AUV.V-K2 A key comparison of   vibration acceleration APMP.AUV.V-K2, which is upgraded from APMP.AUV.V-K1.1,   has been made within the Asia Pacific Metrology Programme (APMP) to include   three national laboratories; the CMS-ITRI (Chinese Taipei), the NIMT   (Thailand) and the A*Star (Singapore). Only one pilot laboratory was the NMIJ   (Japan) that participated to link the RMO APMP results to the CIPM CC key   comparison (CCAUV.V-K2), according to the decision of CCAUV10/D7 in 10th   CCAUV meeting. The admissible acceleration amplitude ranges from 10 m/s2 to   200 m/s2 over the frequency range from 40 Hz to 5 kHz. The RMO APMP results   demonstrate the agreement with the key comparison reference value of   CCAUV.V-K2 within the expanded uncertainties considering the armature effect   of vibration exciter in high-frequency range.

51 Cell Stiffness Characterization   Determined by AFM Changes of stiffness   has been emerged as a bio-marker for identifying cancer-affected cells [1].   Recent research indicated that the stiffness of the cancer cells were less   than their normal cells, regardless of the type of cancer [2]. The loss of   stiffness that can be measured using techniques such as atomic force   microscopy (AFM)[3, 4], and represents a phenotypic edge during tumor   development[5]. Tumor cells often compete for or reside outside of the usual   niches compared to normal cells, and abnormal cell morphology is observed   histologically [6-9]. Out-of-shape or loss-of-stiffness originates from loss   of internal cytoskeleton [10-13] supports and allows cancer cells to migrate   and adapt to other tissues [14, 15]. Abnormal expression or dysregulated   cytoskeleton assembly has been associated with tumorigenesis. Drugs such as   taxols target members of the cytoskeleton, including tubulin, and are used   for cancer therapy [16].

52 Analysis of trace element impurity in   specialty gases by spICP-MS coupled with gas exchange technique Specialty gases, such   as ammonia, hydrogen chloride, and hydrogen fluoride, are widely used in   semiconductor processing. The particulate and metal impurities existed in   gases may have detrimental effect on the quality of the end products.   Therefore, particle monitoring and analysis is important for semiconductor   industry. Impinger is a commonly collector used to trap, pre-concentrate, and   digest the particulates from the cylinder, while the collection efficiencies   was found to be less than 20 % for particles with a diameter less than   micrometer. Direct analysis of specialty gases such as NH3 by ICP-MS is a big   challenge because NH3 can react with sampling water to form NH4OH and   resulted in plasma instability or extinguish during the analysis.
   
    Recently, the technique of single particles inductively coupled plasma mass   spectrometry (spICP-MS) was applied to particle analysis and numerous studies   have established a set of metrological criteria of spICP-MS for sizing or   quantifying various types of nanoparticles. In this study, spICP-MS was used   to directly analyze metallic particulate from cylinder gas. To prevent the   plasma quenching, a gas exchange device (GED) was applied to remove the gas   matrix. After the gas exchange efficiency was optimized, the composition of   particulate impurity from ammonia gas was investigated. The detection limit   of established method is at least 100-fold lower than conventional impinger   method, and could be applied to online monitoring of the particulate contaminants   from the delivered gases without much consumption of cylinder gas.

53 Analysis of trace metallic particle   impurity in ultrapure grade solutions with the technique of spICP-MS Many chemicals are   used throughout the manufacturing process of semiconductor devices. For   example, ammonia hydroxide (NH4OH) and hydrogen peroxide (H2O2) are commonly   used reagents for SC1 cleaning process. SC1 cleaning process is an important   step for removal of surface contaminants from wafer surface. However,   contaminant removal by high pH SC1 process usually results into metal   deposition, which can cause adverse effect on device performance. In   addition, metallic impurities present in the chemicals and chemical mixes can   cause contamination and give rise to defects in the final product, so their   levels must be strictly controlled. The required concentration levels of   impurities in the process chemicals are 1-10 pg/g in the production of size   less than 90 nm structures. For process control by both supplier and wafer   manufacturers, the development of a new analytical method for impurities in 1   pg/g or less is required.
   
   
   
    In this study, single particle inductively coupled plasma-mass spectrometry   (spICP-MS) used for direct analysis of process chemicals including NH4OH,   H2O2, and tetramethylammonium hydroxide is demonstrated. Gold nanoparticle is   used as standard for calibration, and the detection limits of gold nanoparticle   in different reagents are less than 10 nm. In addition, Fe and Al   nanoparticles are found to exist in those process chemicals and the   concentration is at ppt level. The results obtained in this study show that   spICP-MS is powerful tool which can measure particle in a wide variety of   matrices.

54 Cell Stiffness Characterization   Determined by AFM Changes of stiffness   has been emerged as a bio-marker for identifying cancer-affected cells [1].   Recent research indicated that the stiffness of the cancer cells were less   than their normal cells, regardless of the type of cancer [2]. The loss of   stiffness that can be measured using techniques such as atomic force   microscopy (AFM)[3, 4], and represents a phenotypic edge during tumor   development[5]. Tumor cells often compete for or reside outside of the usual   niches compared to normal cells, and abnormal cell morphology is observed   histologically [6-9].

Abnormal expression or dysregulated   cytoskeleton assembly has been associated with tumorigenesis. Drugs such as   taxols target members of the cytoskeleton, including tubulin, and are used   for cancer therapy [16].
   
    In this work, AFM was used to probe cell stiffness at the single cell level   directly on living cells, and immunostaining was used to measure the   expression and distribution of cytoskeleton in cultured cells as well as in   vivo. Cell stiffness was measured using AFM (Bruker) and four-sided pyramidal   tips. The tips (DNP-10) were made of silicon nitride with cantilever length   of 205 mm and the tip radius of 20 nm. The nominal cantilever spring constant   k is 0.06 N/m with estimated resonance frequency in air as f = 12~24 kHz.   Prior to every batch of measurements, the spring constant k of each probe was   calibrated by indenting on a hard substrate. The spring constant was, then,   determined using the thermal tune method. Cells were plated for longer than   12 hours before each measurement and measurements were performed at room   temperature with tips dipped in serum-free media. A 20x20 um2 area was   initially scanned around the cells, and cell stiffness was measured within an   8x8 um2 area. Sixty-four force curves were deduced from each measured cell.   Sneddon’s model was then fit to each curve and the corresponsive modulus was   deduced and compared using Kruskal-Wallis tests and post examined using   Dunn’s multiple comparison. me_HR-transformed MSCs developed into tumors that   clonally expanded in vivo. AFM detected loss of stiffness in   me_HR-transformed MSCs, whereas immunostaining detected reduced tubulin   expression and disorganized F-actin. Use of a DNA methylation inhibitor was   sufficient to suppress tumor progression but did not fully restore actin   organization and stiffness in me_HR- transformed cells. Our data indicate   that me_HR-induced cell transformation is accompanied by the loss of cellular   stiffness and suggest that somatic epigenetic changes might provide   inheritable selection marks during tumor propagation. However, inhibition of   oncogenic aberrant DNA methylation cannot fully restore cellular stiffness.   Therefore, stiffness is a candidate biomarker that reports the physiological   status of a cell.

55 Developing step arrangement and   nanostructure self-organization on sapphire (0001) surfaces The accurate   dimensional measurement is important in the semiconductor industry. The size   of the devices has continued to shrink not only in lateral dimensions but   also in vertical dimensions. According to ITRS 2013, the surface roughness   cannot exceed 2 nm with metrology uncertainty below 0.12 nm, and the   metrology uncertainty for fin height is required to be below 0.6 nm in the   FinFET process parameter metrology requirements [1]. The behavior of devices   can be affected by varied roughness or thickness in the range of several   nanometer or even in atomic scale [2-3]. It needs to confirm the dimensions   to ensure devices quality. Atomic force microscope (AFM) is a tool to   characterize surface topography at nanometer and sub-nanometer scales and   therefore becomes increasingly important in semiconductor industry for   metrology purposes [4-5]. To confirm the accuracy of measurement in the   vertical dimensions, establishing a step height standard for calibrating the   z-magnification of AFM is necessary [6-7]. This study attends to establish   easy-to-use sub nanometer step height standard by arranging atomic step   height on sapphire (0001) surface. Before patterning, the sample was scanned   by AFM (L-trace, Hitachi) to check the surface quality. International   Conference on Metrology and Properties of Engineering Surfaces 20170627
56 Research on the Calibration of   Long-Term Non-ionizing Radiation Monitoring Instruments Over the past few   decades, the electricity and electromagnetic (EM) technologies play very   important roles in our daily life in the applications of household   appliances, broadcasting, personal communications, and so on. However, the   widely established electrical facilities and telecommunication base stations   have resulted in the increased concerns about the effects of EM radiation to   the health of public and thus caused conflict between residents and the power   companies or telecom carriers. In order to reduce the more and more conflicts   arose from the resident around these facilities, the Environmental Protection   Agency (EPA) is planning to establish a long-term environmental non-ionizing   radiation monitoring system so that the publics can access the environmental   EM radiation information through this system via the EPA website.
   
    The object of this research is to draft a proposal for the calibration of   the radio frequency (RF) long-term environmental non-ionizing radiation   monitoring systems. We collected and analyzed the international technical   documents and the research results of advanced institutions about the   calibration of the RF electromagnetic field monitoring meters. Based on these   information, we drafted the calibration method for the RF long-term EM   radiation monitoring systems.

59 Alternative Methods to Evaluate   Photobiological Safety for the Wavelength of (2500~3000) nm Modern technology   makes high luminance lighting become available, but advanced lighting could   also come with potential photobiological hazards. In photobiological safety   standards, (2500~3000) nm infrared radiation is indicated to have   potential
   
    thermal hazards to cornea, lens, and skin. The suggested evaluation method   is through irradiance measurement. However, due to strong IR absorption in   this wavelength range caused by ambient humidity, it is challenging to obtain   irradiance accurately. Two methods were proposed for (2500~3000) nm   photobiological
   
    safety evaluation without the need of irradiance measurements. The goal is   to establish more reliable and practical evaluation methods for the purpose   mentioned.

61 Online monitoring of particulate from   cylinder gases with spICP-MS Special gases, such   as ammonia, hydrogen chloride, and hydrogen fluoride, are widely used in   semiconductor processing. On line monitoring the particulate contamination of   the delivered gases is important challenge. Impinger is a commonly collector   used to trap and pre-concentrate the particulates from the cylinder and then   analyze with ICP-MS. However, collection efficiencies was found to be less   than 20% for particles with a diameter less than micrometer. Moreover, gases   such as NH3 would dissolved in sampling water and become saturated NH4OH   solution which can extinguish the plasma immediately during analysis with   ICP-MS.
   
    The technique of single particles inductively coupled plasma mass   spectrometry (spICP-MS) was recently applied to particle analysis and   numerous studies have established a set of metrological criteria of spICP-MS   for sizing or quantifying various types of nanoparticles.

62 The Experimental and Analytical Tasks   on Wind Farm Noise The study of this   paper focused on the validation of the outdoor noise propagation method and   the implementation to wind farm noise prediction on the nearby residents.   Noise map is a fast and economical method for the noise evaluation and   prediction for noise propagation origin from the specific noise sources.   Through the in-situ metrology works and the numerical prediction tasks on the   wind farm noise, the consistency of the results was achieved from   aforementioned two methods. The maximum deviation was 5 dB(A) for the   experimental and numerical results under the condition where the noise   measurement result was not contaminated by the background noise. 中華民國振動與噪音工程學術研討會 20170603
63 Application of ANSYS CFX in Wind   Turbine fluid-structure interaction Simulation In this study, the   structural analysis software ANSYS was used to analyze the structural   mechanics behavior of the 660 kw Vestas v47 trilobalic horizontal shaft fan   at the wind speed (15 m/s). In the study, the Workbench under ANSYS was used   to analyze the fluid-structure coupling, that is, the computational fluid   dynamics software CFX and ANSYS structural mechanics software were combined   with each other. And according to the relationship between the pitch angle   and the inclination angle and the wind speed, the different terrain   corresponds to the ground roughness coefficient α; in the part of the flow   field area except for the general external flow field, The rotation of the   flow field, because in the process of calculating the fluid analysis of the blade   part of the setting is to rotate, in the part of the incoming wind speed is   in accordance with IEC61400-1 using the wind speed distribution method for   the exponential distribution, the formula Vinlet = Vhub ( Z / Hhub) α, to   explore the stress and deformation of its leaves. 中華民國振動與噪音工程學術研討會 20170603

The wind turbine generator noise levels are   shown with a strongly linear correlation to the wind speeds at the rated   power of 20% to 80%, while the noise levels are almost maintained constant   despite the wind speed is continuously rising until the wind turbine has   reached its maximum rated power. Moreover, the higher the wind speed and the   longer the propagation distances made the larger differences between the   noise experimental survey and numerical prediction results. This means that   over a certain distance and wind speed condition the wind turbine noise   (event noise) will merge in the wind noise (background noise). 台電工程月刊 20170531
65 ASSESSMENT OF THE MEMS ACCELEROMETER   CALIBRATION BY USING THE VERY LOW FREQUENCY PRIMARY VIBRATION CALIBRATION   SYSTEM WITH WIRELESS TRANSMISSION The very low   frequency primary vibration calibration system in Taiwan has been improved.   In order to provide local semiconductor foundry a more reliable way to   calibrate the MEMS accelerometer, three kinds of accelerometers that are   ADXL, PCB 356A15 and QA3000 were tested via such vibration calibration   system. Unlike PCB 356A15 and QA3000, the MEMS type accelerometer, ADXL, was   only performed well under 100 Hz.  All   the three kinds of accelerometers were connected to NI wireless modules in   order to reduce the inconvenience of wires during vibration monitoring. The   result suggests that we shall use MEMS accelerometer with the vibration under   100 Hz. IMEKO TC3, TC5 and   TC22 International Conference 20170531
66 Introduction to International   Vocabulary of Metrology — Basic and general concepts and associated terms   (VIM 3) Metrology is science   of measurement and its application, thus metrology involves a wide range of   fields, such as length, electric, temperature, mass, chemistry, flow, and   even extended to clinical medicine, biology, engineering, food Science, legal   science, microbiology, etc. These fields are also closely related to the   lives of the community. There are many metrological concepts and terminology   in various fields. In most fields, there is no substantial difference in the   principle of basic measurement, but there may be difference between the   measurement idea and the presentation method, it may be inconsistent in the   use of the metrological vocabularies. Thus, it's quite necessary to develop   an international standard document on the basic and general concepts and   associated terms of metrology.
   
    In the effort of the International Metrological Organization, the second   edition of the Basic Standard for International General Metrology was issued   in 1993. After that, on the basis of the social needs and consideration of   the new achievements in the field of measurement standards, the third   edition, ISO/IEC Guide 99: 2007, International vocabulary of metrology-Basic   and general concepts and associated terms, was issued in 2007. In order to   introduce VIM 3 to the relevant personnel in the domestic metrological   fields, this paper will extract and describe the vocabularies and its   definition in VIM 3 , hope the new ideas and terminologies that are expected   to be met in the country could be in line with international metrology.

67 Rapid Determination of Chromium in   Natural Water Using a Centrifugal Microdevice Coupled with Simple Image   Analysis Environmental   pollution caused by chromium (Cr) is closely related to the industrial   activities, such as steel, leather, pigment and rubber industries. Typically,   Cr exists either as cationic trivalent species (i.e., Cr(III)) or anionic   hexavalent species (i.e., Cr(VI)). Cr(III) species are essential in protein   and lipid metabolism. In contrast, Cr(VI) species are capable of inducing   deoxyribonucleic acid (DNA) damage leading to potential cell transforming   effects. Considering Cr(III) species are prone to form more toxic Cr(VI)   species in the environment, the determination of Cr is critical for   evaluating their impacts on the environment and human being. Over past   decades, the microfluidic-based technology has emerged as a popular   methodology for analytical work due to their unique advantages such as low   reagent/power consumption, portability for in-situ use, low fabrication cost,   and versatile design. Among several microfluidic-based techniques available,   centrifugal microdevices have attracted much attention in recent years.   Compared to the usual methods for fluid manipulation in miniaturized systems,   the sample/reagent solutions are driven by centrifugal force without the use   of any other pumping equipment. Thus, more compact designs for analytical   systems can be expected. In this study, we developed a centrifugal device   including a glucamine-packed solid phase extraction column and in-channel   flow control valves. After coupling the developed centrifugal device to   simple image analysis tools, rapid determination of Cr in natural water was   accessible. 分析技術交流研討會 20170527
68 A Self-made Polarization   Interferometer with Laser A self-made   polarization interferometer that is a portable device with a laser light   source is used to measure relative distances, with its theory based on   Michelson interferometer and by using polarization theory to decrease energy   loss of the laser. The interferometer includes four optical detectors mainly   in order to decrease dc current shift, where the sine interference signal is   triggered to become the square interference signal by a Schmitt Trigger   electrical circuit, and then the relative distances is measured by counting   the square interference signal. The verification result shows that the   measurement distance is larger than 25 mm with the error about 0.3 μm, the   resolution 0.08 μm, and the largest speed of the measured reflector at 0.4   m/s. 精密機械與製造科技研討會 20170519
69 The structure design and verification   for shear type accelerometer Piezoelectric   accelerometer is currently the most frequently used sensor for vibration   measurement in industry.Because shear accelerometer has a characteristic   charge output less susceptible to changes in ambient temperature and   deformation of the fixing base, it could reduce the output noise signal due   to temperature deviation or uneven contact surfaces. This paper mainly   describes the design and verification of shear accelerometer. The internal   structure of shear type accelerometer includes an inertial mass, the   piezoelectric material, base structure and a built-in charge amplifier. First   by selecting annular piezoelectric material, design different inertia mass of   stainless and copper tungsten, finite element analysis, porotype   accelerometer manufacture with built-in charge amplifier and verify   accelerometer performance as well. Then we apply the air bearing type shaker   to verify the accelerometer frequency response and sensitivity. From the   finished porotype accelerometer verification result the resonance is up to 15   kHz and frequency response is less than 5 % with frequency below 4 kHz. We   have reached the preliminary target of project. 量測資訊雙月刊(量測中心) 20170501
70 A frequency stabilized   microresonator-based optical frequency comb and its practical technology   development Microresonator-based   optical frequency comb generation system was developed to provide   multi-wavelength laser sources for dense wavelength division multiplexing   (DWDM) fiber optic communication. However, there is not yet a portable and   practical application. In this paper, optical frequency comb which   corresponded to the DWDM channel spacing of about 100 GHz was successfully   generated based on the home-made taper fiber with transmission rate of more   than 80% and high quality factor (Q value>10^7 ) fused quartz   micro-resonator. After we adopted the indirect mounting packaging method and   shockproof design, the reported comb generation system was capable to produce   comb lines after 7 km of travel by a taxi, indicating the effectiveness of   the packaging. This technique could apply in optical communication light   souses and spectrometers in optical communication frequency range for rapid   automatic optical inspection in the future. 量測資訊雙月刊(量測中心) 20170501
71 The improvement of NML high pressure   air calibration system The original sonic   nozzle bank was replaced by a new sonic nozzle array consisting of seven   nozzles which can be operated independently. The throat diameters of the new   nozzles range from 2.312 mm to 11.56 mm, having nominal flow rates of 3 m3/h   to 75 m3/h, and the three largest nozzles have to be operated simultaneously   to achieve the maximum flow rate. Two additional sonic nozzles were installed   downstream of the nozzle array as the check meters. Calibration of the new   nozzles by the primary, gyroscope weighing system shows that the nozzles   operate across laminar to turbulent regimes, and the transition takes place   at the Reynolds number around 106. Positive dependence of transition point on   the nozzle diameter was also observed. Consistency among the standard   nozzles, applicability of combining the nozzles in parallel, long-term   stability and calibration capability were confirmed by flow measurement tests   as well intra comparison with a bell prover. An unofficial bilateral   comparison with PTB through a 6” turbine meter was conducted to verify the   capability of the modified calibration rig. The En values across the tested   flow range were all less than unity, suggesting that the measurement results   are equivalent and CMS’s uncertainty claim of 0.19 % is adequate. Further   improvement of the facility by installing two additional heat exchangers to   recover the heat loss during calibration process is underway. 天然氣應用與計量研討會 20170420
72 Final report on APMP supplementary   comparison of industrial platinum resistance thermometer for range -50 °C to   400 °C. (APMP.T-S6) The National   Metrology Laboratory, Malaysia (NML-SIRIM) had coordinated the Supplementary   Comparison of Industrial Platinum Resistance Thermometer (IPRT) started from   July 2009 until April 2011 together with the National Measurement Institute   of Australia (NMIA) and Korea Research Institute of Standards and Science   (KRISS). This comparison was opened to all APMP members and 16 participants   had taken part in order to consolidate or improve their calibration and   measurement capabilities (CMCs). Three units of artefacts 100-ohm IPRT   belonging to NML-SIRIM, NMIA and KRISS were used and three loops of   measurement were run in parallel to shorten the circulation time. The   stability of artefacts was monitored with initial and final ice point   measurement by each laboratory. The participants need to perform measurement   at temperature points (0,-50,-30, 0, 100, 200, 300, 400,0) °C. All submitted   data were compiled and adjusted at nominal temperature and by using the   linkage from NMIA and KRISS as reference value for all three loops , the   temperature deviation from participants from different loops can be compared.   The approach of Birge Ratio for final exclusion comprised all the excluded   results from the analysis of each loop and the measurement performance for   each participant were summarized by the En number value.

73 Study of Pressure effect on   measurement results for ultrasonic flow meters This paper   investigates pressure effects on measurement results for four ultrasonic flow   meters (USMs) (Elster-Instromet/Q.Sonic-4 Series-IV QL) served as working   standards of gas flow calibration laboratory of Refining & Manufacturing   Research Institute (RMRI) of CPC. These four USMs have traceable calibration   by the national flow standard at CMS at 10 bar, and then they are used to   calibrate meters from customers through changing the internal density   settings corresponding to the practical working pressure. The internal   corrections for USMs include the corrections for Re, flow profile, and   effects of gas pressure and temperature on meter body itself. The technology   for internal corrections for USMs are kind of knowhow for each USM   manufacturer. To find out the behaviors of these four USMs under working   pressure other than 10 bar, an additional pressure test of 50 bar together   with a transfer standard supported by PTB was conducted. Through comparison   of the test results between these four meters and the PTB transfer standard,   the performance of these four USMs operated at different working pressure   conditions can be obtained. Results showed that the difference between two   test pressures of these four USMs were fell within ± 0.2 %, indicating great   internal corrections for these USMs. 量測資訊雙月刊(量測中心) 20170331
74 Ultrathin High-k/Metal Gate Multilayer   Thin Films Thickness Evaluation by X-ray Reflectivity and Electron Microscopy   Technology High-k materials were   conducted for increasing dielectric thickness and reducing short channel   effects. HfO2 is the most widely utilized material for its thermal stability   and process compatibility. Metal gate is applied to replace polysilicon gate   depletion effect and inversion layer. For the next technology node,   high-k/metal gate thickness will be reduced to several nanometers for   improved performance. However, the optical measurement can no longer provide   sufficient resolution for its higher wavelength Grazing-incidence X-ray   Reflectivity (GIXRR) measurement can detect the film density, thickness, and   interface roughness by calculating the reflected X-ray beam   interference.Although transmission electron microscope (TEM) can provide   accurate results, the boundary of high-k and metal layers with high electron   contrast cannot be precisely defined. In this letter, the GIXRR measurement   is applied to characterize ultrathin high-k/metal multiple layer with single   layer thickness lower than 3 nm. As compared to TEM, GIXRR can provide a much   efficient and faster substitution. The target high-k and metal films (Two   samples: 1. TiN 1.0 nm / HfO2 1.5 nm / SiO2 / nm/ Si substrate, and 2. TaN   0.9 nm / TiN 1.0 nm I HfO2 1.5 nm / SiO2 1 nm / Si substrate.) were deposited   by atomic layer deposition (ALD). In this letter, the XRR measuring the   thickness of ultrathin high-k gate oxide and metal film is addressed,   incorporating TEM analyses. The TEM images show an unclear interface between   each layer owing to ultrathin thickness and amorphous phase, therefore it is   hard to actually define thickness. Image contrast intensity is utilized to   evaluate high-k thickness by full-width at half maximum definition. In   conclusion, non-destructive GIXRR method can be provided as a powerful   metrology tool for its fast and accurate measurement, demonstrating its high   potential for application in future semiconductor in-line inspection. Two   different metrology tools show a consistent thickness result. Annual Conference on   Engineering and Information Technology (ACEAIT) 20170329
75 Catalytic Nanoreactors of Au@Fe3O4   Yolk–Shell Nanostructures with Various Au Sizes for Efficient Nitroarene   Reduction Au@Fe3O4 yolk–shell   nanocatalysts based on the thermal decomposition of iron pentacarbonyl in the   presence of 2.5–10-nm Au core nanoparticles were successfully fabricated for   the catalytic reduction of nitroarenes. The particle sizes of the Au@Fe3O4   nanostructures were in the range 8–15 nm, with Fe3O4 shell layer thicknesses   of 2.0–2.4 nm. The Fe3O4 layer not only can form a magnetic shell for   recovery but also enables the protection of the catalytic activity of the Au   core nanoparticles toward the reduction of nitrobenzene derivatives including   2-nitrophenol, 4-nitrophenol, 4-nitrotoluene, and 1-chloro-4-nitrobenzene in   the presence of NaBH4. The catalytic performance of Au@Fe3O4 is highly   dependent on the particle size of the Au core materials and the substituent   groups of the nitroarenes. The reduction rates of nitroarenes with   electron-withdrawing groups were found to be 2.3–2.6 times higher than those   of nitroarenes with electron-donating groups. In addition, the reduction of   nitroarenes by the Au@Fe3O4 yolk–shell nanocatalysts was found to be a   surface-mediated reaction, and the relationship between the reduction rate   and the initial NaBH4 concentration was found to follow Langmuir–Hinshelwood   kinetics. Moreover, the yolk–shell nanoparticles showed good separation   ability and reusability, as they could be repeatedly applied for the nearly   complete reductions of 4-nitrophenol and 1-chloro-4-nitrobenzene for at least   five successive cycles. These unique properties make Au@Fe3O4 nanocatalysts   an ideal platform for tailoring yolk–shell nanoreactors with various active   materials and also for studying various heterogeneous catalytic processes.

76 Vibration Measurement Technology of   PZT and MEMS Type Accelerometer The types of sensors   have been transferring due to the era of IoT. (Internet of Things) Take   accelerometer as an example, the MEMS type has been developed recently. As   the low-cost MEMS accelerometers have been widely used around our daily life,   a lot of people believe the opportunity to replace the traditional PZT   accelerometers. In order to discuss with this, we introduced the principles   of the PZT accelerometers and the MEMS accelerometers. Mounting them to the   vibration calibrator separately helps us to understand their capability of   measuring displacement of vibration signals. Wireless data transfer was   achieved by using NI Wi-Fi modules in order to reduce the inconvenience of   wires during vibration monitoring. Through WSN (Wireless Sensor Network), the   malfunction of the motors inside the smart factory were monitored. Based on   the test result, the MEMS accelerometers were not recommended to be used to   monitor the vibration in the smart factory due to its lager inaccuracy   compared with the PZT ones. However, the correct way to calibrate the   sensitivities of the accelerometers is the key point to build the internet of   things in the near future. 機械資訊 20170310
77 Analysis of Calibration Uncertainty   for Force Transducers In a wide range of   industrial applications, there is the need to measure a (tensile or   compressive) force. These applications range from materials testing to   industrial weighing, and from engine thrust measurement to the proof loading   of bridge bearings. In each application, there will be an uncertainty   requirement on the force measurement – the equipment used to make the   measurement must be traceable to a realization of the SI unit of force (the   newton). Currently, the domestic calibration laboratories (generally   accredited by the Taiwan Accreditation Foundation (TAF)) using the force   transducers system force calibration machines to calibrate force-measuring   instruments (such as force transducers, force -proving instruments etc.).  
   
    This paper takes the force calibration machines of the National Measurement   Laboratory as an example, to illustrate the measurement results and the   uncertainty estimate for calibrating the force transducers. And estimate all   of the uncertainty contributions in the manner described in the EURAMET cg-4   [1].

78 The Principle and Uncertainty Analysis   for Ruska 2465 Low Range Piston Gauge Piston gauge, which   is also called dead weight tester or pressure balance, includes both types of   gas-operated and liquid-operated. It is a pressure calibration instrument   with excellent long-term stability. In this paper, the Ruska 2465   gas-operated piston gauge was used as the pressure standard. It includes the   principle discussion, the establishment of the measurement equation in gauge   pressure mode and the uncertainty estimation for the 170 kPa low range   piston. As the result shown in this paper, the smallest uncertainty for the   digital manometer calibration against the Ruska 2465 low range piston gauge   is 0.006 kPa ( a level of confidence of approximately 95%). 量測資訊雙月刊(量測中心) 20170301
79 Mechanical Properties Analysis and   Application of Nanoindentation Nanoindentation is   adopted as an important technique for measuring the mechanical properties of   materials. Indentation impressions are created by applying the indenter to   the sample surface. The hardness and reduced modulus can be calculated from   using the known geometry and material property of the indenter and indenting   load-displacement data. Therefore, the capability of force-displacement   transducer used in nanoindentation instrument should be evaluated to make   sure providing precise measurement services. This report describes how to   evaluate the uncertainties of indentation system and its applications. When   the applied force is smaller than 10 mN and the displacement is in the range   from 50 nm to 300 nm, the relative expanded uncertainties of hardness and   reduced modulus are 2.7 % and 3.1 % respectively (by a coverage factor k = 2   and providing a level of confidence of approximately 95 %). 量測資訊雙月刊(量測中心) 20170301
80 Measurement standard and technology of   dynamic expansion method This paper presents   the method for the vacuum gauge calibration by dynamic expansion method. The   evaluation method is based on ISO/IEC Guide 98-3:2008, Uncertainty of   measurement — Part 3: Guide to the expression of uncertainty in measurement   (GUM:1995). The influences of error sources are analyzed while performing the   calibration works. There are two standard gages used in this system.They are   Ion Gage (IG) and Spinning Rotor Viscosity Gage (SRG), respectively. The   expanded uncertainty of IG was from 3.27×10-7 Pa to 5.03×10-4 Pa when the   calibration range was from 4×10-6 Pa to 8×10-3 Pa. The expanded uncertainty   of SRG was from 1.76×10-5 Pa to 5.85×10-2 Pa when the calibration range was   from 6×10-4 Pa to 2 Pa. 量測資訊雙月刊(量測中心) 20170301
81 Final Report on the APMP Key   Comparison Liquid Hydrocarbon Flow (APMP.M.FF-K2.a) A key comparison,   APMP.M.FF-K2.a was undertaken by the APMP Technical Committee for Fluid Flow,   and was piloted by the National Metrology Institute of Japan (NMIJ/AIST). The   objective of this key comparison is to demonstrate the degree of equivalence   of the hydrocarbon flow standards held at the participating laboratories   (CMS, NMIA and NMIJ), to link the key comparison reference value (KCRV) of   CCM.FF-K2 and to provide supporting evidence for the calibration and   measurement capabilities (CMCs) claimed by the participating laboratories in   the Asia-Pacific regions. A screw type positive displacement flow meter was   selected as a transfer standard. The performance of the transfer standard and   its stability was evaluated from repeated measurements by the pilot   institute, NMIJ. The transfer standard showed high performance and good   stability since the uncertainty due to the transfer standard was less than   quoted uncertainties in the participants. CMS and NMIJ have En values which   show consistency with both the relevant KCRV for APMP.M.FF-K2.a and each pair   of participants. However some En values for NMIA were from 1 to 1.2,   indicating 'alert'. Metrologia 20170201

The missions based on the contract in 2014   are achieved as follows. 科學月刊 20170125
83 Miniaturized Terahertz time domain   spectroscopy system The frequency of   Terahertz (THz) wave is between visible and microwave, and has been widely   used for non-destructive inspection and imaging on various materials.   Although the Terahertz technology based commercial products have been   available internationally, it is still expensive. In this paper, architecture   of parallelized Terahertz beam is constructed to perform a miniaturized, cost   effective, and alignment easily Terahertz time domain spectroscopy system.   The size is 48 cm x 34 cm x 18 cm (width x length x height) with measurable   bandwidth up to 3.5 THz. By measuring the absorption spectrum of glucose   powder, the system's measurement capability was confirmed. In addition, a   frequency doubling light source that excited by a fiber laser was included to   realize a portable Terahertz time-domain spectrum analysis and measurement   system for other applications. 量測資訊雙月刊(量測中心) 20170101
84 The double balance lever of torque   standard machine with 5 kNm calibration capability in CMS In order to improve   the performance of torque standard machine, a good design and manufacture of   double-lever balance is essential, it was both to ensure sufficient rigidity,   but also to ensure there is enough sensitivity. According to specifications,   the initial load limit and the maximum load limit of the sensitivity of not   more than one of ten thousands. To this aim, we apply knife and knife-seat is   fulcrum of the double balance arm lever, and on both sides of lever also use   knife and knife-seat to connect left and right dead weight groups. In this   report, we will present the results of measurement. 量測資訊雙月刊(量測中心) 20170101
85 UPM A proposed method is   based on a model that investigates the tool position error related to motion   of B-axis rotation, and it further calculates the error compensations of   toolpath for B-axis rotation.    Experimental tests evaluated the (A) performance of the B-axis   alignment (B) performance of the B-axis compensation for a cutting spherical   lens, and (C) minimization of form errors according to the analyzed machining   errors.  Experimental results show that   the developed technology has successfully compensated the form errors of   spherical lens from peak-valley (P-V) to achieve around 50 %.  Hence, the novel compensation mechanism   proposed in this paper can effectively compensate form errors of the   ultra-precision machine tools. 量測資訊雙月刊(量測中心) 20170101
