“Everything is Connected to the Genocide.” Intergenerational Memory, Diaspora Mobilization, and Armenian Youth Identities in Jerusalem
Authors:   The Hebrew University of Jerusalem, Levenson Lance
Published: March 2022

Considering commemorative practices of postmemory, past presencing, and transnational memory, this study considers how Genocide memories and the conflict in Artsakh intersect to shape the performance of diasporic Armenian youth identities in Jerusalem as members of a disempowered minority community. Drawing on ethnographic research in Jerusalem’s Armenian School, participant-observation in community events, and interviews with youth and community leaders, this article documents processes of intergenerational memory transmission within educational and community settings and suggests ways in which inherited narratives of victimization find new expressions via transnational acts of citizenship. As Jerusalem’s multilingual Armenian youth engage in commemorative ceremonies and take protests to the streets in acts of diaspora mobilization, memories are (re) interpreted to construct novel identity narratives tied to an imagined Armenian transnation.
A Framework for Training Classes for Dimensional Measurement Incorporating 3D Printing Artifacts
Authors:   Mechanical Engineering  Technology, Fuehne Joseph P. ,   Purdue Polytechnic Institute
Published: March 2022

A partnership between industry and academia has led to developing a framework for a series of training courses for various industrial employees who have different needs and requirements based on their job function. Purdue Polytechnic Columbus is working with local employer Cummins Inc. to define several training classes that would take place at the university campus in Columbus using the environmentally-controlled metrology lab at the facility. Training classes will be outlined for new employees who have no prior experience with metrology, current employees with some metrology experience who may need to update their skills or acquire new skills in a different area, degreed engineers who likely have little metrology experience but need some metrology knowledge to better function in their jobs, and managers who might need an overview of metrology and its key role in the manufacturing environment. These training sessions will necessarily vary in length and time based on the target audience and the depth of knowledge required. The objective is to do as little lecturing as possible and focus the learning on hands-on, learn-by-doing activities. This would include using hand tools, optical measurement tools and various machines that might include surface finish testers, coordinate measuring machines, roundness testers, and torque calibration instruments. A primary aspect of the classes will be measurement artifacts manufactured using 3D printers that would allow the creation of parts with flaws and imperfections that highlight the measurement process and the value in being diligent and aware when performing measurements.
A Submicron Automated Precision Line Scale Calibration System Developed at the Standards and Calibration Laboratory (SCL)
Authors:   Standards and Calibration Laboratory, Tang George C.W. ,   The Government of the Hong Kong Speciall Administrative Region
Published: March 2022

A submicron automated precision line scale calibration system was developed at the Standards and Calibration Laboratory (SCL) in Hong Kong. The system provided a measuring capability for line scale of range 0.01 to 750 mm with measurement uncertainty of[0.152 + (0.0005*l)2]1/2 μm (l in mm). The fully automated system used the displacement method and employed an air bearing stage driven by a piezoelectric motor. A pixel-counting system was integrated with a microscope to enhance accuracy. The system used only one laser interferometer to compensate the Abbe error in two lateral directions. Without further calculation, any angular movement leading to an Abbe error would be automatically compensated. The uncertainty contributed from Abbe effects was evaluated to be within 30nm, an error reduction of over 95 % of the Abbe effect when such an arrangement was not in place.
STEM and Metrology Education Outreach In New Hampshire
Authors:   Hinton Technical Services, LLC, Hinton William
Published: March 2022

When skilled metrology practitioners leave the industry due to retirement, career change or simply exit the field, we have difficulty obtaining replacement staff with the required training and experience. This is especially critical with the lower numbers of Metrologists coming out of the armed forces. Metrology is historically not a scientific field or career path discussed in the school systems and is rarely understood or discussed by career counselors. The NCSL International Learning and Development initiated the Metrology Ambassador concept whereby Metrology professionals within NCSLI are provided support to engage students and teachers within the community and make them aware of the STEM based world of metrology. My entry into the position of Metrology Ambassador began 15 years ago, and now embraces events ranging from first graders through students in the local community college system. Local industry partners work with me to produce age appropriate STEM/Metrology. These Metrology Ambassadors work with the Governor’s High Tech Council, Girl’s Technology Day event organizers, the governor’s STEM Task Force, the Pre-Engineering Technical Advisory Council and school staffers. There will be examples of things that worked and things that did not. Statements will be provided by teachers, State Department of Education (DOE) staff and students who have participated in these events. This is a long-term project considering the time it takes to expose students to STEM in general and Metrology specifically before we will see results manifested by positive change in the number of people entering these fields. We will need support from all sides to achieve our goal.
Ultrastable Low-Noise Current Amplifier: A New Tool for Small Current Metrology
Authors:   Physikalisch-Technische Bundesanstalt (PTB), Scherer Hansjörg
Published: March 2022

The Ultra stable Low-noise Current Amplifier (ULCA) is a user-friendly and superior alternative to existing instruments for small direct currents in the range between about 1 fA and 5 μA. The principle of the portable laboratory table-top device, operated at room temperature, is based on a novel dual-stage transimpedance amplifier concept. The total transimpedance of 1 GO is calibrated with a cryogenic current comparator with an uncertainty < 0.1 μO/O traceable to the quantum Hall resistance. The output voltage is measured with a voltmeter calibrated traced to the Josephson voltage standard. In addition to its electrometer function, in combination with a voltage source the ULCA also can be used as a current generator. Therefore, it represents a new tool for ultra-accurate small-current measurement and generation traceable to quantum electrical standards. It outperforms commercial devices and calibration setups used in metrology institutes by up to two orders of magnitude in accuracy. The unique features of the ULCA are the excellent stability of its transimpedance (drift less than 5 μO/O per year, short-term fluctuations over one week< 0.1 μO/O), its small temperature coefficient (typically about 0.2 μO/O per Kelvin), fast settling(difference to final value < 0.1 μA/A after 3 s), and the low input current noise of 2.4 fA/vHz. This enables measuring a direct current of 100 pA with a total relative uncertainty of 0.1 μA/A in about 10 h. Besides being excellently suited for R&D in small-current metrology (e.g. for research on single-electron pumps) the ULCA is also widely applicable for calibrations, for instance for electrometers, small-current sources, or high-value resistors. Corresponding fields (and specific examples) are electronic industry (ICs), medicine and biotechnology (dosimetry, radiation protection, DNA sequencers) as well as environmental monitoring (concentration measurements of small particles in air or aerosols), and lighting industry (photo current measurement). Framed by two patent applications, the technology was transferred from the Physikalisch-Technische Bundesanstalt (PTB) to a German company (Magnicon GmbH, Hamburg), which manufactures and markets the ULCA since 2016 licensed by PTB.

Use of Current Transformers in Calibrations of Rogowski Coils at High Pulsed Currents
Authors:   National Research Council Canada (NRC), Djokic Branislav
Published: March 2022

Rogowski coils (RCs) are widely used for measurements of high AC currents, transient currents and impulse currents. In AC resistance welding, they are used as current sensing coils (CSCs) in conjunction with weld-current meters/monitors (WCMs) for monitoring/controlling the weld currents, and thus ensuring the quality of welds. The CSCs are calibrated stand-alone or with WCMs at high pulsed currents at conditions close to those encountered in the field. These ´gated’ sinusoidal currents with variable angle of conduction deviate from sinusoidal waveform, and their harmonic content is large. This requires high sampling rate and integration, which affects negatively measurement uncertainty. In spite of the CT core-saturation, size, weight and cost constraints for measurements at large currents, they are used as reference devices in the calibrations of RCs at steady-state AC currents. A special electronically-enhanced CT was developed for the calibration of RCs in a copper coaxial cage at high pulsed currents of up to 35 kA. The implementation of this CT as the reference in a calibration system for Rogowski coils at high pulsed currents, which requires no integration, will be discussed in the paper, including traceability to SI units. Preliminary estimates of the measurement uncertainty will be given.

The New American Standard for Digital, Dial, and Vernier Calipers
Authors:   Mitutoyo America Corporation, Salsbury James
Published: March 2022

A new American standard for digital, dial, and vernier calipers, ASME B89.1.14, was approved by the ASME B89 dimensional metrology standards committee in 2017, and final publication of the standard is expected in 2018. The purpose of this paper is to introduce the new standard and discuss some of the key developments. In particular, the standard includes default specifications and calibration test methods that will have a major impact to calibration services. This paper will review the history of the development of the standard and discuss all the major sections of the standard, including specifications, rated operating conditions, test methods, conformance decision rules, and measurement uncertainty. The relationship between ASME B89.1.14 and the international standard for calipers, ISO 13385-11, will also be discussed.
The Future of the Mass Artifact in the New SI
Authors:   National Institute of Standards and Technology (NIST), Mulhern Edward
Published: March 2022

As the International System of Units continues the transformation from a system based on fundamental units to one based on fundamental constants the question is often asked: what will happen to the artifacts that once served as the cornerstone of the realization process? In the case of the kilogram, it is a common misconception that the International Prototype Kilogram (IPK) and its copies will have little more than historical value as the kilogram takes on its new definition based on the Planck Constant. The truth of the matter is, stable artifacts will be just as important in the new realization and dissemination of mass. At the National Institute of Standards and Technology (NIST), artifacts will play an integral role in the mise en pratique, or practical method, for the realization and dissemination of the new mass standards. The kilogram will be realized in the NIST-4 Watt Balance, where the power generated by moving a mass artifact through a gravitational field will be balanced by an electrical power involving quantum standards. From there, it is the artifact that will be transferred under vacuum, via a custom mass transport vehicle, to either a vacuum balance for sorption studies or the NIST Magnetic Suspension Mass Comparator for a direct calibration of another artifact in air. Following this, the artifacts will be housed in either vacuum or air environments, comprising the pool of standards from which mass is disseminated to customers. To prepare for this new system of mass, the Mass and Force Group has taken exquisite care to control the conditions that these artifacts will be exposed to. Identical chambers have been designed and fabricated to provide two separate environments for mass artifact storage. One chamber will be kept under vacuum and the other will contain filtered lab air at nominally atmospheric conditions. In this paper the design, fabrication and assembly of the chambers will be detailed. The mass transfer and handling processes employed by the Mass and Force groups will be explained. Finally, the overall impact of the redefinition on the artifact-based mass system will be discussed.
An Introduction to Dynamic Force Metrology
Authors:   National Institute of Standards and Technology (NIST), Vlajic Nicholas
Published: March 2022

The ability to measure rapidly time-varying quantities is a continued and growing interest in the metrological community, which has been driven, in part, by the need to accurately measure dynamic mechanical quantities (e.g., pressure, force, acceleration). Within the mechanical domain, force indicating instruments are different from most other types of sensors, as the force sensor must also transmit the quantity being measured. Consequently, the force measurement instrument becomes part of the engineering structure or measurement system. While this integration of sensor-system typically does not pose many design or metrological challenges for static or stationary forces, the implications for dynamic measurements are often profound. For example, high-performance force transducers can be statically calibrated with less than 10 parts-per-million uncertainty (k=1); however, the dynamic sensitivity has been shown to deviate by several orders of magnitude from the static sensitivity for certain rates of dynamic forces. We describe some of the physical challenges in making accurate dynamic force measurements, as well as commonly used dynamic force calibration techniques. The introductory dynamic force concepts covered here serve as a foundation for designing engineering systems with the intent of measuring time-varying forces.
Uncertainty Propogation for Force Calibration Systems
Authors:   Morehouse Instrument Company, Zumbrun Henry
Published: March 2022

There are several labs operating throughout the world, which does not follow a designated guideline for calculating measurement uncertainty for force calibrations done in accordance with the ASTM E74 standard. Realizing the need for a guidance document, Morehouse decided to draft this document explaining how to calculate measurement uncertainty and how uncertainty propagation for force calibration systems works. The document examines uncertainty contributors for different tiers in the calibration hierarchy. We start with tier one laboratories using primary standards which are dead weight machines and work through the uncertainty propagation through tier two or secondary laboratories and then tier three laboratories. Calibrations, repeatability studies, and other tests were performed at each tier using different types of force calibration equipment. The paper follows the uncertainty progression and answers a question of what type of calibration standard and Calibration and Measurement Capability (CMC) is needed to achieve a specific Calibration and Measurement Capability at the next tier. Through examining the various uncertainty contributors we arrive at a conclusion that several force scopes may not be realistic in their CMC claims which means they may not be able to make statements of conformance. The testing proved the importance of the reference standard in relation to overall expanded uncertainty. Deadweight primary standards are predictably the best possible reference standard. A laboratory using secondary standards—those standards calibrated by deadweight—can achieve CMC’s as low as 0.02 % of applied force if they are using several standards. Nonetheless, the downside of using several standards is that this method involves standards to be changed at least once during the calibration which often further impacts test results. Failing to account for all the uncertainty contributors at any tier and not calculating Calibration and Measurement Capability properly will influence the Unit Under Test (UUT) in several ways resulting in lower combined uncertainties and raising measurement risk levels on all instruments in the entire measurement chain.
Accurate Temperature Representation of Stored Goods Using an Algorithm as a Replacement to a Physical Buffer
Authors:   AmericanPharma Technologies, Rusnack Michael
Published: March 2022

The CDC’s publication entitled, "Guidelines for Storage and Temperature Monitoring of Refrigerated Vaccines" recommends using a glycol bottle for refrigerator applications. As the glycol acts as a thermal buffer, it reduces probe sensitivity to air temperature fluctuations within the refrigerator cabinet. NIST studies have demonstrated that temperature probes in glycol-filled bottles can more closely approximate vaccine vial temperatures when placed in the same refrigerated area where the vaccine is stored. Current CDC guidance does not specify a specific volume or geometry for the buffer. This leaves open to interpretation the specifics of the buffering methodology. Our review of physical thermal buffers currently utilized in the general industry shows little consistency in the geometric shape, with volumes ranging from 10 to 300 ml. It was also observed that pre-filled syringes as small as 0.25 ml were being stored, which is significantly smaller than the volumes of physical buffering being used. This is especially important with respect to freezing, as the volume of physical buffering would not provide accurate notification of compromised vaccines. The use of telemetry in the measurement and monitoring of equipment is not only necessary but essential to the successful prediction of the unit operation as well as the demonstration of a close approximation of the contents. The telemetry available from the raw air temperature probe will provide valuable information on the unit’s performance both near and long term. One of the multiple telemetry streams that can be derived from the raw air temperature is virtual temperature buffering. That is an algorithmic based representation of the volume to be represented. A fixed buffer assumes the entire content is a single volume, where this is rarely accurate. The application of a virtual temperature buffer, one can accurately simulate any volume and shape that is maintained in the storage unit. With virtual buffering, the effect of an excursion can be accurately applied to each volume rather than a blanket assumption that all volumes are affected the same. This presentation describes the development and evaluation process of a virtual buffering process that has been demonstrated to be highly accurate and repeatable.
Risk-Based Thinking in the Calibration Laboratory: Practical Examples
Authors:   International Accreditation Service, Inc. (IAS), Alexander Helga
Published: March 2022

Many calibration laboratory managers, who plan to become accredited or re-accredited to the new ISO/IEC 17025:2017 standard, worry about how to address a new requirement of the standard: considering the risks and opportunities associated with laboratory activities. They may not realize that a well-run calibration tivities. Practical examples of consideration of risks and opportunities in routine laboratory activities such as calibration interval determination, out-of-tolerance investigations, root cause analysis of nonconformity incidences, etc., will be addressed, and suggestions on how to enhance, monitor and document such activities will be provided. Laboratory personnel will find that they do not have to start from scratch in order to comply with this new aspect of ISO/IEC 17025, but they can leverage and improve upon existing best practices.
More Efficient Solving Calibration Issues by Automated and Semi-Automated Calibration Systems
Authors:   National Space Organization, Lee Tsung-Ping
Published: March 2022

From year 2015, owing to National Space Organization (here shorted by NSPO) internal a great quantity of requirements for instruments calibration, automated and semi-automated calibration systems started to build up, writing by computer programs C# to control and retrieve data from varies instruments and modules, in brand of instruments for example: Agilent, FLUKE, HP ,Keithley, Keysight, National Instruments and Tektronix. In order to solve issues of automatically generating uncertainties and calibration reports, templates using Microsoft Word according to the characteristics of the instrument have been classified and created. It benefits in calibration efficiency and precision because data retrieving and calibration reports can be created only one button. At the same time, calibration records can be found including uncertainty and degree of freedom of each component, expanded uncertainty and effective degree of freedom. After 2 years calibration experience, NSPO started to apply accreditation of Taiwan Accreditation Foundation (TAF) and have been accredited from April 10, 2017 by TAF. In order to satisfy requirements of TAF, for example: calibration report’s format, the logic of computer program by C# have been modified and validated by TAF. Therefore, NSPO can issue a report with both TAF logo and ILAC-MRA logo after calibrated instruments for customers. Owing to customers trust, NSPO stated to service external customers from May of 2017. Nowadays, NSPO have set up systems including Power Supply, Multi-Functions Meters, NI-4431 module series, Multi-functions Signal Generator, Current Probes, Electric-Load and Thermo-couple Meters. Systems in building and planning are Oscilloscope (building), Signal Conditioner (docs building) and Ionizing-gage/meters (planning, for High-Vacuum chambers). The main purpose to join this workshop is to share benefits of automated and semi-automated calibration system and to understand requirements from end-users.

Annual Cycle of Hygroscopic Properties and Mixing State of the Suburban Aerosol in Athens, Greece
Authors: Spitieri Christina , Gini Maria , Gysel-Beer Martin , Eleftheriadis Kostas
Published: March 2022

Abstract. The hygroscopic properties of atmospheric aerosol were investigated at a suburban environment in Athens, Greece, from August 2016 to July 2017. The Growth Factor Distribution Probability Density Function, (GF-PDF), and mixing state were determined with a Hygroscopicity Tandem Differential Mobility Analyzer, (HTDMA). Four dry particle sizes, (D0), were selected to be analyzed in terms of their hygroscopic properties at 90 % relative humidity. The annual mean GFs for D0 = 30, 50, 80, and 250 nm, were found to be equal to 1.28, 1.11, 1.14, and 1.22 respectively. The hygroscopic growth spectra can be divided into two distinct hygroscopic ranges; a non or slightly hygroscopic mode (GF ˂ 1.12) and a moderately hygroscopic mode (GF ˃ 1.12), which are representative of a suburban environment influenced by local/regional emissions and background aerosol. The standard deviation σ of the GF-PDF was employed as a measure of the mixing state of ambient aerosol. The 30 nm particles were mostly internally mixed, whereas larger particles were found to be externally mixed, with either a distinct bimodal structure or with partly overlapping modes. Cluster analysis on the hourly dry number size distributions measured in parallel, provided the link between aerosol hygroscopicity and growth/evaporation dynamics. The size distributions were classified into five groups, with the “mixed, urban and aerosol background” (67 %) and “urban-nocturnal” aerosol (12 %) to account for 79 % of the results. The hygroscopic properties for 50 nm and 80 nm were found to be similar in all cases, indicating particles of similar nature and origin across these sizes. This was also confirmed through the modal analysis of the average number size distributions for each cluster; the 50 nm and 80 nm particles were found to belong to the same Aitken mode in most cases. The 250 nm particles (i.e. accumulation mode) were generally more hygroscopic than Aitken particles, but less hygroscopic than the 30 nm particles (nuclei mode).
Continuous mapping of fine particulate matter (PM2.5) air quality in East Asia at daily 6  ×  6 km2 resolution by application of a random forest algorithm to 2011–2019 GOCI geostationary satellite data

Abstract. We use 2011–2019 aerosol optical depth (AOD) observations from the Geostationary Ocean Color Imager (GOCI) instrument over East Asia to infer 24 h daily surface fine particulate matter (PM2.5) concentrations at a continuous 6 × 6 km2 resolution over eastern China, South Korea, and Japan. This is done with a random forest (RF) algorithm applied to the gap-filled GOCI AODs and other data, including information encoded in GOCI AOD retrieval failure and trained with PM2.5 observations from the three national networks. The predicted 24 h GOCI PM2.5 concentrations for sites entirely withheld from training in a 10-fold cross-validation procedure correlate highly with network observations (R2 = 0.89) with a single-value precision of 26 %–32 %, depending on the country. Prediction of the annual mean values has R2 = 0.96
and a single-value precision of 12 %. GOCI PM2.5 is only moderately successful for diagnosing local exceedances of the National Ambient Air Quality Standard (NAAQS) because these exceedances are typically within the single-value precisions of the RF and also because of RF smoothing of extreme PM2.5 concentrations. The area-weighted and population-weighted trends of GOCI PM2.5 concentrations for eastern China, South Korea, and Japan show steady 2015–2019 declines consistent with surface networks, but the surface networks in eastern China and South Korea underestimate population exposure. Further examination of GOCI PM2.5 fields for South Korea identifies hot spots where surface network sites were initially lacking and shows 2015–2019 PM2.5 decreases across the country, except for flat concentrations in the Seoul metropolitan area. Inspection of the monthly PM2.5 time series in Beijing, Seoul, and Tokyo shows that the RF algorithm successfully captures observed seasonal variations in PM2.5, even though AOD and PM2.5 often have opposite seasonalities. The application of the RF algorithm to urban pollution episodes in Seoul and Beijing demonstrates high skill in reproducing the observed day-to-day variations in air quality and spatial patterns on the 6 km scale. A comparison to a Community Multiscale Air Quality (CMAQ) simulation for the Korean peninsula demonstrates the
value of the continuous GOCI PM2.5 fields for testing air quality
models, including over North Korea, where they offer a unique resource.
