Tornando visíveis os atores sociais que lutam contra o invisível
Authors: Lara Marina
Published: March 2022

Durante o caminhar etnográfico sobre minha pesquisa nos tempos de pandemia, fui tomada por um sentimento descrito anteriormente por Margaret Mead (1975, p. 3), discípula de Franz Boas e Ruth Benedict. Para além da importância da descrição antropológica dos sujeitos, senti a necessidade de torná-los visíveis. Não obstante, vivemos em um momento que sugere distanciamento social entre pesquisador e entrevistados, e o sentimento de contato é aflorado com o passar dos dias. Assim sendo, em uma tarde ensolarada de uma quinta-feira do mês de setembro, inevitavelmente comecei a observar a vida que acontecia fora de mim. Ainda que não possa ver os atores específicos da pesquisa, sair pelas ruas do centro da cidade de Cuiabá me fez compreender, através de imagens, que há um mundo de atores sociais a serem seguidos (Latour, 2012, p. 31): eis aqui o resultado fotográfico do meu encontro com os cuidados, conhecimento, fé e esperança.
Casa como elemento do parentesco em duas localidades no sul do Brasil
Authors: Wiggers Raquel
Published: March 2022

Apresento duas etnografias onde a casa e as formas de morar definem relações sociais locais. Uma é uma comunidade urbana na periferia de Florianópolis pesquisada na década de 90 a outra é uma localidade rural no sul da Ilha de Santa Catarina. A análise de casas inspirada em trabalhos de antropólogos como Lévi-Strauss, Bestard e Pina Cabral, foi central para compreender a dinâmica e a organização social dos dois locais das pesquisas. Cada um a seu modo acionam noções de casa e morar.

Palavras-Chave: Casa; parentesco; organização social.
A forma auto-organizada da produção dos espaços públicos de vizinhança: o caso do bairro do Conjunto Ceará em Fortaleza (CE)
Authors: Holanda Barbosa Rodrigo , Jacó de Freitas Geovani
Published: March 2022

Esse artigo apresenta-se como aporte dos amadurecimentos de pesquisas etnográficas sobre a produção dos espaços públicos do Conjunto Ceará, na cidade de Fortaleza. Nos conta a história oficial do bairro, oriundo de um projeto urbanístico estatal e das lutas dos movimentos sociais pela preservação/reconhecimento desses espaços. Em seguida, traçando um contraponto, narra a história que opera no detalhe do cotidiano dos espaços públicos, apresentando a auto-organização como um processo pelo qual, a partir de ações desencadeadas por si mesmas, agentes, como os moradores do Conjunto Ceará, transformam os espaços públicos que fazem parte de suas vidas, superando dificuldades e atualizando potencialidades. A produção auto-organizada dos espaços públicos de vizinhança pelos próprios moradores aparece como parte vital de uma forma de habitar, inventiva, astuciosa e cotidiana, bem como, uma ação política de sujeitos comuns sob a banalidade do seu cotidiano, que esconde um potencial grandioso, porém fragmentado, de produção da realidade.Esse artigo apresenta-se como aporte dos amadurecimentos de pesquisas etnográficas sobre a produção dos espaços públicos do Conjunto Ceará, na cidade de Fortaleza.

Subalternidade nas sociologias brasileira e indiana: um estudo comparativo da obra de Jessé Souza e Gayatri Spivak
Authors: Ferreira Fabio Alves
Published: March 2022

As sociedades brasileira e indiana são muito desiguais. Ambos países não constroem igualmente uma cidadania para todos. Para Jessé Souza, é preciso criticar a ciência brasileira pois ela foi a responsável por manter este tema invisível na literatura. Spivak também concorda que a desigualdade é mantida epistemologicamente e culturalmente, além do econômico. Assim, emergem grupos e classes sociais subalternizadas. Para ambos é preciso criar condições institucionais que assegurem o reconhecimento e a plena cidadania para todos as classes sociais e/ou grupos subalternos.

Justiça restaurativa: acordos e cooperação
Authors: Oliveira Samyle Regina Matos , Santana Selma Pereira Pereira de
Published: March 2022

Este artigo objetiva demonstrar que a Resolução 225/2016 do CNJ, em seu art. 3º, III, amplia a possibilidade de aplicação da Justiça Restaurativa. Defende-se, contudo, a ideia de que acordo decorrente da Justiça Restaurativa constitui um negócio jurídico (conceito lógico-jurídico) que pode produzir efeitos, entre juízos cooperantes, no âmbito da Cooperação Judiciária Nacional (art. 6º, inciso XIX da Resolução 350/2020 do CNJ), aplicando-se a conflitos que possuam repercussões em diferentes competências (além da seara criminal). O trabalho adota o método de revisão bibliográfica, normativa e documental, com uma abordagem hipotético-dedutiva. A partir do levantamento realizado é possível, concluir, portanto, que apesar dos espaços normativos que a Justiça Restaurativa tem no ordenamento jurídico brasileiro, ainda é preciso i)Vencer a resistência oferecida pelos próprios profissionais do sistema de justiça e dos operadores do direito, no geral, às transformações propostas pela JR; ii) Avaliar quais os processos restaurativos que são capazes de equalizar os valores e princípios da Justiça Restaurativa, com a necessidade de racionalização dos processos; iii) Ampliar o debate sobre a aplicação da Justiça Restaurativa no âmbito dos tribunais, com seriedade, a fim de identificar os limites para sua aplicação em determinada área.
Altruism and the Dark Triad
Authors: Trahair Cassidy , MacDonald Kristi B. , Furnham Adrian , Schermer Julie
Published: March 2022

Background

The Dark Triad literature examining pro-social behaviours is minimal, with mixed results.

Participants and procedure

This study investigates the relationships between the Dark Triad and altruistic behaviours based on self-report data from 286 adults. Altruism was assessed using two scales: a general measure as well as a more recent scale measur-ing compassionate altruism towards family, friends, and strangers.

Results

Machiavellianism negatively correlated with general altruism; however, when controlling for the other dark variables plus age and gender in a regression, narcissism was the only Dark Triad trait that significantly predicted altruism. None of the Dark Triad traits were significantly related to or predictive of compassionate altruism.

Conclusions

This study demonstrates that the Dark Triad and altruism relationships are not straightforward, and that, surprising-ly, strong negative relationships between the traits and altruism are not found. Limitations and future research direc-tions are discussed.

Kampong French
Authors: Duruz Jean
Published: March 2022

Abstract: This paper refers to accounts of previous journeys on the ‘laksa trail’ in search of Peranakan cuisine and its sensory nuances. These journeys have produced narratives of migration and diaspora, shaped by the re-location of dishes and ingredients from local villages, coffee houses and home kitchens of Malaysia and Singapore to cafés and restaurants of Adelaide, Australia and Toronto, Canada. On this occasion, however, the argument comes full circle, focusing on nostalgic tastes, smells and textures that resonate in Singapore itself. The intention is to trouble meanings of authenticity in terms of specific communities’ dishes, ingredients and culinary rituals, and to frame the argument through the rich body of scholarship emerging since Fernando Ortiz’s seminal discussion of transculturation in Cuban Counterpoint (1995). Kampong French, established in the lush gardens of Singapore’s Open Farm Community, provides a ‘pop-up’ example of transculturation within a specific culinary contact zone (Pratt 1996; Farrer 2015)­—a sense of the plasticity of dishes, ingredients and meanings. It may be tempting to dismiss these re-inventions of traditional dishes and ingredients as opportunistic seizure of the ‘exotic’ or simply as expressions of creative entrepreneurialism, or even as ‘inauthentic’ adventuring on behalf of the palates of privileged middle-class consumers. Unravelling the political implications of these experiments in nomadism, however, suggests there is more to learn about meanings of authenticity in historically ‘mixed’ communities—about authenticity’s less obvious refractions of movement, ethnicity, identity and place and, in particular, about the complex ways these meanings are ingested in twenty-first century multi-culinary global cities.
The Local and Global in the Armenian Genocide Memorial
Authors:   Armenian Genocide Museum-Institute Foundation, Marutyan Harutyun
Published: March 2022

Memorials are one of the most common forms of memorialization and may be understood as symbolic reparations for the victims and survivors of mass violence. They acknowledge the suffering and grief of the victims and pay tribute to the dead. At the same time, the memorials epitomises not only history but also teaches contemporary lessons of local and global character. The Armenian Genocide Memorial as a symbol of grief and revival of the Armenian nation serves all these aims. This article aims to address some points of history of the construction of the Armenian Genocide Memorial, its local and global implications, the issue of absence of names in the Memorial, as well as the feelings of patriotism and statehood embedded in the Armenian Genocide Memorial.

A New, Gateway Class Emphasizing Metrology
Authors:   Purdue University, Fuehne Joseph
Published: March 2022

The Purdue Polytechnic Institute is one of ten colleges on the campus of Purdue University in West Lafayette, Indiana. Also included in the Institute is an outreach effort that includes ten locations spread throughout the state of Indiana to engage local communities and industries and to provide an alternative to the main campus for traditional and non-traditional students in those geographic areas. One of those areas is Columbus, Indiana, about an hour south of Indianapolis, and this paper relates experiences from that location. The Purdue Polytechnic Institute is using modernized teaching methods that are "research-proven, state-of-the-art teaching methods that are different, fun, challenging and more effective." One element of this is to bring these methods to a first-semester class so that the newest students can experience these methods and understand what to expect over their time with the Polytechnic Institute. Purdue Polytechnic Columbus is unique among the outreach locations due to a partnership with diesel-engine manufacturer Cummins Inc. that has led to an environmentally-controlled metrology lab located within the university facility. The lab contains a calibrated coordinate measuring machine, calibrated tensile tester, a surface finish instrument, a roundness tester and a plethora of donated hand tools including calipers, micrometers, height gauges, bore gauges, PI tapes, sine blocks, and several sets of gauge blocks. This new class attempts to integrate nearly all facets of the metrology lab into the learn-by-doing activities to provide a fun, unparalleled experience for the first-time students. Activities described in the paper include micrometer calibration using gauge blocks, a study of springs using a height gauge and mass standards, pressure and force measurements of footballs, load-displacement characteristics of various bandages, and calculation of volume and surface area of various objects using calipers, micrometers, and rulers. In all cases, students are required to summarize data by developing graphs and tables using spreadsheet software.
Disaster Recovery: Managing the Recovery From the 2017 Northern California Wildfires
Authors:   Keysight Technologies, Dobbert Michael
Published: March 2022

On October 8th, 2017, multiple catastrophic wildfires broke out in Northern California, resulting in loss of life and $3.3 billion in damage. The fire displaced a significant portion of the community due to evacuations and destroyed homes. Keysight Technologies corporate headquarters and the homes of many employees, were located inside the burn perimeter of the Tubbs fire. After the fire, the site was inaccessible for several days, with only limited access thereafter. Several of the main Keysight buildings experienced smoke and water damage. These buildings house corporate activities, R&D, marketing and manufacturing operations, a standards laboratory and a testing laboratory. The primary impact from the smoke was a light coating of soot and a smoky odor inside the buildings, which required extensive cleaning. Water damage was minimal. While the condition of calibration standards and electronic testing equipment was initially unknown, testing revealed negligible impact from the smoke and soot. This paper discusses the processes for re-establishing calibration status and traceability, the challenges in bringing revenue generating operations back on-line and the value of business recovery planning.
Inter Laboratory Comparison of High Resistance Standard in Japan
Authors:   National Metrology Institute of Japan (NMIJ) / AIST, Kaneko Dr. Nobu-Hisa
Published: March 2022

To validate a calibration capability of calibration laboratories, it is necessary to carry out an appropriate inter laboratory comparison. However, as is often the case with some extreme ranges of the measurements, e. g., extremely high resistance, it is difficult to arrange such a comparison. In this study, in the collaboration work between the National Metrology Institute of Japan (NMIJ/AIST) and calibration laboratories, an inter-laboratory comparison for extremely high resistance standards as high as 100 TΩ has been established. The demonstration of validation of calibration capability has been performed from 1 MΩ to 100 GΩ with a set of stable high-resistance standard resistors circulating among three participants. The NMIJ/AIST provided the reference value for this comparison, and each of the three participants calibrated the circulated set of artifacts employing their system built to be traceable to the national standard. Although the equipment and traceability scheme differed among the participants, the results agreed well and the En values of each laboratory were below 1. At the conference, the protocol and final report of this comparison will be presented.

A Measurement Method for Chromaticity and Photometric Quantity of Laser Displays
Authors:   HIOKI E.E. Corporation, Hieda Keisuke
Published: March 2022

In recent years, an increasing number of displays have been adopting lasers to benefit from their high color reproducibility, enhanced energy efficiency and small size. As the use of lasers in displays is growing, the demand for precise measurement of their chromaticity and photometric quantity is rising in order for manufacturers to ensure their display quality. However, tristimulus-value direct-reading method, which has been a commonly-used measurement method in the optical industry, cannot meet the required chromaticity accuracy of ±0.0150 due to lasers’ extremely narrow spectra. To solve the measurement problem, we propose a new measurement method developed for laser displays, which is called the discrete centroid wavelength method (DCWM). The DCWM calculates chromaticity and photometric quantity based on the centroid wavelength and radiometric quantity of lasers, which is a different measurement principle from the tristimulus-value direct-reading method. Our numerical analysis which simulated measurements of red, green and blue lasers by the DCWM showed that the DCWM has a chromaticity accuracy of 0.0065 and meets the required accuracy. We concluded that the DCWM is an appropriate measurement method for laser displays.
Practical Correlation in Repetitive Measurements
Authors:   Metrology Consultant, Dubro Dennis
Published: March 2022

Anyone who is conversant with the standard G.U.M. method for calculating uncertainties using the so-called “Law for the Propagation of Uncertainties” knows that it is important to include any correlations among the components in the calculation. We have all seen simple examples of correlation, such as the comparison of height and weight in a sample of people. But in calculating an uncertainty budget with correlated uncertainties, it is not possible to measure the correlation coefficients. They have to be estimated. It is a fact that any two instruments which are not perfect, will have errors which will be correlated. Unless one has a perfect calibration standard, the correlation coefficient cannot be measured. This paper deals with a practical example calibrating thread wires in which 18 short term measurements are recorded using the same micrometer. During the short time of the calibration, many of the Type B uncertainties will be constant, although they will most likely vary tomorrow, next week and next year. This paper will show a method for estimating the correlation coefficient for uncertainties for calculated parameters such as roundness, taper and the master average.
Effective Management Review
Authors:   Tektronix Inc., Fleenor Jennifer
Published: March 2022

Many organizations go through the motions of a management review so that they have documentation to pass a third party audit, however the review is often not effective. The reason they are not effective is managers do not take the time to prepare, collect and analysis available data, not enough time is scheduled with Top Management, and what time is available, the participants do not feel it is well spent or value added. A Top Management’s review is intended to ensure the organization’s quality management system is suitable, adequate, effective, and aligned with the strategic direction of the organization. If your management review is not effective, you can expect to have nonconformities in the fulfillment of your calibration and/or test activities. This session will provide recommendations on how to complete a management review so that the process is effective in both function and time, and participants feel the process if value added to the organization while meeting the documented requirements of ISO 9001:2015, ISO/IEC 17025:2017, ANSI-NCSL Z540-1:1994 (2002), ANSI-NCSL Z540-3 2006 and any your accrediting body. Advice on a management review schedule, template, documentation, and follow-up action management will be shared. Participants will have the opportunity to interact throughout this interactive workshop and offer their ideas and experience so that all participants gain knowledge and learn how to prevent pitfalls and obstacles of a successful, meaningful management review. As a requirement of metrology industry Standards, management reviews are a necessity, so why not make the process effective and value added to your organization?
Computer Aided Verification of Voltage Dips and Short Interruptions Generators for Electromagnetic Compatibility Immunity Test in Accordance with IEC 61000-4-11:2004 + AMD: 2017
Authors:   Standards and Calibration Laboratory, Wah Lai Hau ,   The Government of the Hong Kong Special  Administrative Region
Published: March 2022

The operation of electrical and electronic equipment may be affected by disturbances in the supply network. Voltage dips and short interruptions are common disturbances that involve sudden reduction of the supply voltage below a certain voltage level followed by restoration after a short interval. They are usually caused by faults in the electricity supply network such as presence of short circuit or by sudden large variation in electric loading. These unwanted electromagnetic interferences may cause malfunctioning of or even damage to the equipment. Therefore, it is important to conduct voltage dips and short interruptions immunity tests on electrical and electronic products. Voltage dips and short interruptions generators are key equipment for conducting immunity tests and these generators need to be verified. This paper describes a computer aided system developed by the Standards and Calibration Laboratory (SCL) for verification of voltage dips and short interruptions generators in accordance with the international standard IEC 61000-4-11 (2004-03). The parameters that can be calibrated are: ratios of the residual voltages to the rated voltage; the rise time, fall time, overshoot and undershoot of the switching waveform; and the accuracy of the phase angle at switching. A specially built adapter is used to convert the high voltage output waveforms of the generators to lower level signal to be acquired by a digital oscilloscope. An in-house developed software then analyses the captured signal to calculate the required parameters. The paper also discusses the uncertainty evaluations for the measured parameters.
Taxonomies for a Metrology Information Infrastructure
Authors:   Pantex Metrology, Kuster Mark
Published: March 2022

What if your organization’s measurement, analysis and management computing systems spoke a shared language with other world-wide measurement-related systems? How would that affect your business? How would it ease your ISO/IEC 17025 compliance challenges? Imagine a set of normative standards that define data structures, taxonomies, service protocols and security for locating, communicating and sharing measurement information. Those standards comprise what we call a measurement information infrastructure, or MII. In 2017, the NCSLI MII & Automation Committee presented the MII Vision and held discussion on its progress. This year’s open discussion panel session focuses on the taxonomies required to implement an MII and highlight how you may participate in the real-world benefits it will create and the efforts underway to realize them. The session will also demonstrate some MII-aware software under development.
The Fundamental Problem in Thread Gaging and Thread Gage Measurement
Authors:   JJ Calibrations, Inc., Fletcher Travis
Published: March 2022

The aim of this report is to analyze measurements of screw threads and thread gaging against specification requirements. The purpose is to not only communicate proper techniques, methods, and technologies, but also to present this information in a clear and concise manner that can be understood by manufacturers of threaded components, calibration laboratories, gage manufacturers, and advisory committees for screw thread specifications. The primary intent of the studies and information contained in this document is to open up a dialog between all parties involved in thread measurement and gaging to address a fundamental problem that has been discovered regarding adjustable thread ring gages and their applicable specifications. To perform the studies, thread set plugs were analyzed using the traditional super micrometer and 3-wire methods while thread ring gages were analyzed using the traditional set plug methods. These measurement results were then compared to results obtained using the newer technology of contact scanning. The results of these studies have indicated that it is very unlikely that adjustable thread ring gages are capable meeting dimensional specifications. In one portion of this study, a sample of 30 adjustable thread ring gages were measured using the contact scanning method. Of these samples none were found to meet specifications. In another portion of this study adjustable thread ring gages were properly set to the correlating thread set plugs. When measured using the contact scanner method the rings were found out of tolerance to specified requirements. The samples of adjustable thread rings were found out of tolerance for all pitch diameter measurements. After several unsuccessful attempts to adjust the pitch diameters into tolerance while keeping the minor diameters in tolerance, it was concluded that the closer the pitch diameter reading got to meeting the defined specifications, the rings would no longer thread onto the thread set plug correctly. With recent technological advances in measurement and this information being presented along with further studies in process, it is absolutely critical that specifications on thread ring gages be reviewed and reconsidered. It doesn't make any sense to have specifications that can not be achieved.
Oxidization, Contamination, and Automation for High Temperature Verification of Thermocouples
Authors:   Boston Scientific, Imholte Mike
Published: March 2022

During the process of verifying K type thermocouples at high temperatures, the sheath turns gray or breaks down and flakes off. This creates a risk of contaminants and damage to product in a vacuum braze furnace. The cost of recertifying the thermocouples and cleaning of the furnace block when a thermocouple sheath breaks down is high. After working through this process for many years, I came up with a new furnace setup that reduces the potential for contamination of product. This paper will explain the process, verification station set up, tools and materials used to reduce oxidization of the sheath material. We have updated from an inconel isotheral block furnace to an alumina isotheral block furnace. This eliminates the contamination to the reference PRT being it also has an alumina sheath. The why is when an alumina sheath is contaminated with inconel the OEM will not calibrate the PRT because of possible contamination to the silver fixed point cell. The automation improvement has reduced cost in labor and down time.
Thermocouple Testing Methods, Data Analysis and Reporting Calibration Results with Emphasis on Noble Metal Types
Authors:   Fluke Calibration, Kolat Tom
Published: March 2022

Thermocouples are rugged, fast responding temperature sensors that very often cover large ranges of temperature. In addition, their economical affordability and ease of adaptation to a variety of configurations serve to increase their popularity and consequently the customer demand for traceable calibrations. Like all other measurement and test equipment, thermocouples, due primarily to their classification categories, exhibit a range of performances and accuracy expectations. This establishes the need for several methods of testing and analysis for effective, accurate result reporting with respect to the written standard and the temperature scale. This paper and its presentation discuss approaches employed to calibrate thermocouples and report their calibration results. It continues by illustrating some of the mathematics that can be used to furnish results on the calibration certificate. Examples of those applications with realistic thermocouple data are shown.
Primary Sinusoidal Calibration of Pressure Transducers
Authors:   SPEKTRA GmbH, Mende Michael
Published: March 2022

Pressure transducers are frequently used in dynamic environments such as combustion engines, aerospace applications or industrial process control. Like for every measurement task it is essential to know the uncertainty of the obtained measurement result, even in a dynamic environment. Therefore it is remarkable that there is no traceable standardized method to quantify the frequency response of a pressure transducer. Due to this lack of investigation methods the authors have made an effort to develop a primary method to calibrate pressure transducers dynamically. This method allows to measure the frequency response with sufficient pressure amplitudes up to 1 MPa in a frequency range up to 10 kHz. In the paper the pistonphone based apparatus is presented. This pressure generator compresses a liquid by a piston. The fundamental idea is to determine the pressure rise of the employed fluid primarily by measuring the movement of the piston. Therefore the mass balance is applied to the device and leads to Ṗ=KA Ẋ/V0 Where Ṗ is the dynamic pressure, K is the bulk modulus, A is the area of the piston, V0 is the initial volume of the fluid and Ẋ is the velocity of the piston. The frequency response of the transducer is then calculated by (f)=U(f) Ṗ(f)Where U(f) is the frequency dependent output of the transducer. Besides a detailed discussion of the apparatus, the paper includes the investigation of the measurement uncertainty. Namely the uncertainty contribution of the piston area A, the initial volume V0 and the deviation between an iso-thermal bulk modulus K at low frequencies and the adiabatic bulk modulus at higher frequencies. Furthermore first measurement results will be presented, which confirm the test setup and the primary approach to measuring the frequency response.
ISO 17025:2017: Design of the New Calibration Certificate
Authors:   Technical Center for Information Technology 81, Mihm Gerhard
Published: March 2022

ISO/IEC 17025:2017 will be published by end of 2017. New requirement of ISO/IEC 17025:2017 e.g. is the statement of conformity. It is expected that most of the customers sending in test & measurement equipment for calibration ask for the statement of conformity. If the calibration order does not contain the technical specification of the item; the calibration lab has to deal with the customer to receive the specification required, and the calibration lab will send back with the price quotation the specification of a routine calibration. As ISO/IEC 17025:20177 does not require the print out of the calibration certificate, but needs to be signed, an electronic signature within an unchangeable electronic document has to fulfill all of the requirements of ISO/IEC 17025:2017. German armed Forces with NATO partners developed the standard ALogP-33.1 and the national defense standard VG 96910, which are in line with ISO 17025:2017. Statement of conformity should be in accordance with ILAC-G8:2009-03. The presentation will show the concept of this standard, the way of setting up technical specifications (according to ISO 10012 with metrological confirmation) and also discuss problems that arose in getting the standard into service.
Calibration Laboratories Challenges - Service Quality
Authors:   Metrology Program Consultant & Technical Manager, Sajid Ahmed Shaikh ,   Saudi Specialized Laboratories  Co. Motabaqah
Published: March 2022

This paper is written from the perspective of either third party commercial or an internal calibration lab. While it is recognized that some companies communications go through multiple departments (both for the customer and for the calibration service provider), these experiences and solutions may also be applied to any lab needing outsourced calibration services. It is imperative that both the customer and the vendor take equal responsibility for communicating with each other to ensure complete customer satisfaction. Both the customer and vendor should be familiar with the requirements of ISO/IEC 17025:2005 section 4.41 Review of requests, tenders and contracts, 4.61 Purchasing services and supplies, and Section 4.71 Service to the customer. This paper addresses common frustrations between customers and their vendor’s, it also explains the relationship between different factors and processes involve in delivering the best quality services. Moreover, it also offers valuable suggestions to overcome the current and future challenges that are faced by calibration laboratories. Apart from this, certain solutions are also offered in this manuscript for closing various gaps that affects the service quality by integrating services gap model to the real scenarios and also explains how this model can help us to deliver best services within the calibration, inspection and testing laboratories.
Analysis of Different Assigned Value Determination Methods on Gauge Block Calibration Proficiency Testing
Authors:   Center for Measurement Standards/Industrial Technology Research Institute, Hung Chen-Yun
Published: March 2022

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 order to understand the gauge block calibration capacity of the domestic laboratories in Taiwan, the Center for Measurement Standards / Industrial Technology Research Institute (CMS/ITRI) held and completed a gauge block calibration proficiency testing in 2016. In this proficiency testing, CMS used the calibration results from National Measurement Laboratory (NML) to determine the assigned value and its expanded uncertainty which were used to calculate the |En| values. 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, including using the results from one laboratory, consensus values from participant results, etc. In order to explore the impact of choosing different methods to determine the assigned value and its expanded uncertainty for proficiency testing results, CMS recalculated the |En| values by using different assigned value determination method after the end of this proficiency testing. Thus, the narrative of this paper contains not only results of this gauge block calibration proficiency testing but also results of using different assigned value determination method to recalculate participant performance statistics.

Derived from the calibration training provided by US Air Force up to the late eighties, German Armed Forces established an own calibration organization, to provide calibration services for most of the test & measurement equipment and for all branches. As test & measurement equipment has to be recorded and registered before coming into service, the program office for test & measurement/calibration has to be involved in the procurement of any product. The metrological confirmation according to ISO 10012 ensures, that the test equipment selected meets the requirements for the measurement or test needed. The metrological confirmation is also used for the procurement of test & measurement equipment and is the baseline for the calibration of the item. The presentation will show the concept of procurement of test & measurement equipment.

Abstract. Beijing suffers from poor air quality, particularly during wintertime haze episodes when concentrations of PM2.5 (particulate matter with a diameter < 2.5 µm) can peak at > 400 µg m−3. Black carbon (BC), an aerosol which strongly absorbs solar radiation, can make up to 10 % of PM2.5 in Beijing. BC is of interest due to its climatic and health impacts. BC has also been found to impact planetary boundary layer (PBL) meteorology. Through interacting with radiation and altering the thermal profile of the lower atmosphere, BC can either suppress or enhance PBL development depending on the properties and altitude of the BC layer. Previous research assessing the impact of BC on PBL meteorology has been investigated through the use of regional models, which are limited both by resolution and the chosen boundary layer schemes. In this work, we apply a high-resolution model (UCLALES-SALSA) that couples an aerosol and radiative transfer model with large-eddy simulation (LES) to quantify the impact of BC at different altitudes on PBL dynamics using conditions from a specific haze episode which occurred from 1–4 December 2016 in Beijing. Results presented in this paper quantify the heating rate of BC at various altitudes to be between 0.01 and 0.016 K/h per
µg/m3 of BC, increasing with altitude but decreasing around PBL top. Through utilising a high-resolution model which explicitly calculates turbulent dynamics, this paper showcases the impact of BC on PBL dynamics both within and above the PBL. These results show that BC within the PBL increases maximum PBL height by 0.4 % but that the same loading of BC above the PBL can suppress PBL height by 6.5 %. Furthermore, when BC is present throughout the column, the impact of BC suppressing PBL development is further maximised, with BC causing a 17 % decrease in maximum PBL height compared to only scattering aerosols. Assessing the impact of these opposite effects, in this paper, we present a mechanism through which BC may play a prominent role in the intensity and longevity of Beijing's pollution episodes.

Abstract. Enduring and extensive heavy precipitation events associated with widespread river floods are among the main natural hazards affecting central Europe. Since such events are characterized by long return periods, it is difficult to adequately quantify their frequency and intensity solely based on the available observations of precipitation. Furthermore, long-term observations are rare, not homogeneous in space and time, and thus not suitable to running hydrological models (HMs) with respect to extremes. To overcome this issue, we make use of the recently introduced LAERTES-EU (LArge Ensemble of Regional climaTe modEl Simulations for EUrope) data set, which is an ensemble of regional climate model simulations providing over 12 000 simulated years. LAERTES-EU is adapted for use in an HM to calculate discharges for large river basins by applying quantile mapping with a parameterized gamma distribution to correct the mainly positive bias in model precipitation. The Rhine basin serves as a pilot area for calibration and validation. The results show clear improvements in the representation of both precipitation (e.g., annual cycle and intensity distributions) and simulated discharges by the HM after the bias correction. Furthermore, the large size of LAERTES-EU also improves the statistical representativeness for high return values above 100 years of discharges. We conclude that the bias-corrected LAERTES-EU data set is generally suitable for hydrological applications and posterior risk analyses. The results of this pilot study will soon be applied to several large river basins in central Europe.

Abstract. Coastlines potentially harbor a large part of litter entering the oceans, such as plastic waste. The relative importance of the physical processes that influence the beaching of litter is still relatively unknown. Here, we investigate the beaching of litter by analyzing a data set of litter gathered along the Dutch North Sea coast during extensive beach cleanup efforts between the years 2014 and 2019. This data set is unique in the sense that data are gathered consistently over various years by many volunteers (a total of 14 000) on beaches that are quite similar in substrate (sandy). This makes the data set valuable to identify which environmental variables play an important role in the beaching process and to explore the variability of beach litter concentrations. We investigate this by fitting a random forest machine learning regression model to the observed litter concentrations. We find that tides play an especially important role, where an increasing tidal variability and tidal height leads to less litter found on beaches. Relatively straight and exposed coastlines appear to accumulate more litter. The regression model indicates that transport of litter through the marine environment is also important in explaining beach litter variability. By understanding which processes cause the accumulation of litter on the coast, recommendations can be given for more effective removal of litter from the marine environment, such as organizing beach cleanups during low tides at exposed coastlines. We estimate that 16 500–31 200 kg (95 % confidence interval) of litter is located along the 365 km of Dutch North Sea coastline.
