Design and Development of a Mobile Robotic System for Aircraft Wing Fuel Tank Inspection
Authors: Dhoot Manpreet Kaur , Fan Ip-Shing
Published: March 2022

This paper presents the design concept behind a novel remote visual inspection robotic system for fighter jet aircraft wing fuel tank inspection. This work is part of a larger research project which focuses on design, simulation, physical prototyping and experimental validation of a robotic system. Whereas this paper specifically focuses on the development concept of locomotion design choice for the robot. Therefore without an effective mobility method the robot will not be able to fulfill its purpose to access the hazardous confined spaces of the fuel tank. Aircraft wing fuel tank inspection is a challenging area of maintenance which requires a considerable amount of preparation and involvement of several tasks in order to conduct effective Visual and Non Destructive Inspection. The environment of an aircraft wing fuel tank poses several challenges due to both physical and atmospheric constraints which can be detrimental to human personal. This paper introduces an effective locomotion design which should allow the robot to enter and maneuver within confined spaces. The robot is relatively small, approximately 70mm in height and width yet, flexible enough to move within the restricted spaces of the wing. The mobile robot platform is a combination of small track systems that articulate like a snake. An additional mobile platform deploys an inspection sensor to reach the spaces that are unreachable by the robot body. Like other proposed robotic systems this particular proposal differs as it allows the robot to enter from the root of the wing and reach the narrower spaces towards with the wing tip. This paper highlights the stakeholder requirements to illustrate the foundation of the robotic system design. An overview of current complications of wing fuel tank inspection is presented and the analysis of current proposed robotic systems for wing fuel tank inspection. An engineering design methodology approach is followed for this project. Several locomotion methods are evaluated and an innovative locomotion method is illustrated with the use of CAD models. The desired outcome of this research is to eliminate the entry or close contact with the fuel tank by human personal.
Development of Exfoliated Graphite using Innovative Chemical Technique for Aerospace Applications
Authors: Devakki Basavaraj , Thomas Shijo , Suryanarayana Ramesh Chinnakurli
Published: March 2022

Several conventional methods on preparation of exfoliated graphite are in practice. However, their major limitations are poor quality of exfoliated graphite, lower yield, more expensive with higher processing time. To address these issues, a unique method for development of exfoliation of graphite using tri-solvents namely Water, Ethanol and Acetic acid is attempted in the present work. Ethanol acts as a supporting group for the long term stable dispersions of ex-graphite nanosheets. Glacial acetic acid, which readily dissolves in water, penetrates through the layers of graphite sheets and breaks the -C=C bond force between layers with the help of stirring and sonication resulting in exfoliation of graphite layers. Exfoliated graphite nanosheets were produced by using optimized mixtures of water, acetic acid and ethanol.

XRD, SEM and FTIR studies have been carried out on the developed exfoliated graphite. Nanosheets of exfoliated graphite with size ranging from 100 nm to 150 nm were obtained while using an optimal mixture of water, ethanol and glacial acetic acid of 75 ml, 40 ml and 200 ml respectively with a stirring time of 6 hrs and sonication time 16 hrs. FTIR studies have confirmed the presence of -C=C at wavenumber of 1652 cm-1 and demonstrates the formation of graphene.

It was observed that the quality of exfoliated graphite and yield were improved from the present method of processing of graphene nanosheets. Further, the process time is less when compared with existing conventional methods. As the exfoliated graphite nanosheets possess lower value of coefficient of thermal expansion, excellent chemical resistance & stability coupled with higher flame retardancy, they can be potential candidate novel nano materials for aerospace applications as coatings against the harsh climate of the space.

Published: March 2022

This study assessed the role played by the existing marketing strategies in terms of positioning Dundee July rural horse racing event (in uMzinyathi District Municipality, KwaZulu-Natal Province, South Africa) on the tourism map, both within the province, and in South Africa at large. This study adopted the exploratory qualitative research method using purposive semi-structured interviews to collect data for analyses; hence its results are not conclusive. There is a further need to collect quantitative data from current and prospective attendees, on a larger scale, to validate the study findings and model customer expectations (customer orientation). However, this study’s exploratory findings revealed that the current marketing strategies and tools are not effectively promoting this event to attract a larger number of spectators and participants. As a feasible solution, this paper puts forward practical recommendations, emphasising on conditions, new marketing strategies and the right combination of both traditional and digital marketing tools to attract a critical mass of attendees to this event. Emphasis was also made on the best way to utilise appropriate marketing mix to position this event. The experience-setting must align to the original rustic nature of this event to optimise its authenticity.

Authors: Völz Lisandro , Limberger Bernardo Kolling
Published: March 2022

Estudos sobre acesso lexical têm priorizado línguas majoritárias em detrimento das línguas minoritárias. Porém, as comunidades de falantes de língua minoritária, como o hunsriqueano e o pomerano, demonstram um interesse cada vez maior em ler e escrever em uma de suas línguas maternas. Diante disso, o objetivo deste trabalho é discutir questões metodológicas envolvidas na seleção de palavras escritas em hunsriqueano e pomerano para uma tarefa de decisão lexical. Com esse experimento, investigamos o acesso a palavras escritas em língua minoritária. Este estudo discute as especificidades da seleção de estímulos psicolinguísticos em duas línguas minoritárias, considerando principalmente a falta de materiais escritos e de padronização, as diferenças entre ambas as línguas e as semelhanças com a língua alemã. A contribuição deste estudo evidencia a importância de pesquisas que envolvam línguas minoritárias, a fim de cooperar nas necessidades dos falantes, favorecendo, assim, a manutenção das línguas minoritárias.
Preliminary Design of Seismic Isolation Systems Using Artificial Neural Networks
Authors: Barakat Samer A. , AlHamaydeh Mohammad H.
Published: March 2022

This works attempts to implement artificial neural networks (ANN) for modeling Seismic-Isolation (SI) systems consisting of Natural Rubber Bearings and Viscous Fluid Dampers subject to Near-Field (NF) earthquake ground motion. Fourteen NF earthquake records representing two seismic hazard levels are used. The commercial analysis program SAP2000 was used to perform the Time-History Analysis (THA) of the MDOF system (stick model representing a realistic five-story base-isolated building) subject to all 14 records. Different combinations of damping coefficients (c) and damping exponents (α) are investigated under the 14 earthquake records to develop the database of feasible combinations for the SI system. The total number of considered THA combinations is 350 and were used for training and testing the neural network. Mathematical models for the key response parameters are established via ANN. The input patterns used in the network included the damping coefficients (c), damping exponents (α), ground excitation (peak ground acceleration, PGA and Arias Intensity, Ia). The network was programmed to process this information and produce the key response parameters that represent the behavior of SI system such as the Total Maximum Displacement (DTM), the Peak Damper Force (PDF) and the Top Story Acceleration Ratio (TSAR) of the isolated structure compared to the fixed-base structure. The ANN models produced acceptable results with significantly less computation. The results of this study show that ANN models can be a powerful tool to be included in the design process of Seismic-Isolation (SI) systems, especially at the preliminary stages.
Concurrency and Petri Net Models
Authors: Staines Anthony Spiteri
Published: March 2022

Concurrency is a fundamental problem and a solution applicable to different areas of computing. Given the complexities and distribution of computer systems and services, concurrency is a modern area requiring proper attention. Petri nets are formalisms based on process representation both from a mathematical view and from a graphical or drawing like view. Petri nets are used to model concurrent processes. This work deals with understanding and representing low level concurrency in Petri nets, when this is not always visible and properly noted from the graphical structure. In this study an algebraic notation has been devised and is used to represent the Petri net structures. This algebraic notation is used as an alternative and simplified way of representation. The notation is explained and several simple examples are given. The notation presented can be used in conjunction with other Petri net analysis and verification methods. Some results and findings are discussed.

Comprehensive assessment of reliability and validity for the clinical cases in simulated community pharmacy
Authors: Amirthalingam Palanisamy
Published: March 2022

Background: The objective structured clinical examination (OSCE) is used to measure the clinical competence of pharmacy students in a community pharmacy setup. However, the OSCE needs to be standardised to assess the clinical competence of the student accurately.

Objectives: The present study was aimed to assess the reliability and validity of two clinical cases used in the simulated community pharmacy.

Methods: OSCE simulation was performed by the students with two clinical cases in a simulated community pharmacy. The reliability was measured using Cronbach’s α and Mc Donald’s ω. Exploratory factor analysis (EFA) and Confirmatory factor analysis (CFA) were used to measure the validity of the cases.

Results: Among the two cases, the first case scenario was found to have a good model fit. However, the second case scenario has a poor model fit which was determined by the CFA. The inadequate sample size and factor loading in EFA were the main reasons for poor model fit in the second case scenario.

Conclusion: The internal consistency, sample adequacy, factor loading, test for an exact fit, and fit measurements should be ensured for the clinical cases included in OSCE. This will help the academician to ensure the accurate assessment of the clinical competence of the student in a simulated community pharmacy.
Security of COFB against Chosen Ciphertext Attacks
Authors: Khairallah Mustafa
Published: March 2022

COFB is a lightweight Authenticated Encryption with Associated Data (AEAD) mode based on block ciphers. It was proposed in CHES 2017 and is the basis for GIFT-COFB, a finalist in the NIST lightweight standardization project. It comes with provable security results that guarantee its security up to the birthday bound in the nonce-respecting model. However, the designers offer multiple versions of the analysis with different details and the implications of attacks against the scheme are not discussed deeply. In this article, we look at a group of possible forgery and privacy attacks against COFB. We show that the security for both forgery and privacy is bounded by the number of forgery attempts. We show the existence of forgery and privacy attacks with success probability qd/2n/2, given qd forgery attempts. In particular, we show an attack with 2n/2 attempts using only a single known-plaintext encryption query against COFB. While these attacks do not contradict the claims made by the designers of GIFT-COFB, they show its limitations in terms of the number of forgery attempts. They also show that, while COFB generates a 128-bit tag, it behaves in a very similar manner to an AEAD scheme with 64-bit tag. As a result of independent interest, our analysis provides a contradiction to the main theorem of Journal of Cryptology volume 33, pages 703–741 (2020), which includes an improved security proof of COFB compared to the CHES 2017 version. Finally, we discuss the term nqd/2n/2 that appears in the security proof of GIFT-COFB and CHES 2017, showing why there is a security gap between the provable results and the attacks. We emphasize that the results in this article do not threaten the security of GIFT-COFB in the scope of the NIST lightweight cryptography requirements or the claims made by the designers in the specification document of the design.
The Legendre Symbol and the Modulo-2 Operator in Symmetric Schemes over Fnp
Authors: Grassi Lorenzo , Khovratovich Dmitry , Rønjom Sondre , Schofnegger Markus
Published: March 2022

Motivated by modern cryptographic use cases such as multi-party computation (MPC), homomorphic encryption (HE), and zero-knowledge (ZK) protocols, several symmetric schemes that are efficient in these scenarios have recently been proposed in the literature. Some of these schemes are instantiated with low-degree nonlinear functions, for example low-degree power maps (e.g., MiMC, HadesMiMC, Poseidon) or the Toffoli gate (e.g., Ciminion). Others (e.g., Rescue, Vision, Grendel) are instead instantiated via high-degree functions which are easy to evaluate in the target application. A recent example for the latter case is the hash function Grendel, whose nonlinear layer is constructed using the Legendre symbol. In this paper, we analyze high-degree functions such as the Legendre symbol or the modulo-2 operation as building blocks for the nonlinear layer of a cryptographic scheme over Fnp.Our focus regards the security analysis rather than the efficiency in the mentioned use cases. For this purpose, we present several new invertible functions that make use of the Legendre symbol or of the modulo-2 operation.Even though these functions often provide strong statistical properties and ensure a high degree after a few rounds, the main problem regards their small number of possible outputs, that is, only three for the Legendre symbol and only two for the modulo-2 operation. By fixing them, it is possible to reduce the overall degree of the function significantly. We exploit this behavior by describing the first preimage attack on full Grendel, and we verify it in practice.
Bounds for the Security of Ascon against Differential and Linear Cryptanalysis
Authors: Erlacher Johannes , Mendel Florian , Eichlseder Maria
Published: March 2022

The NIST Lightweight Cryptography project aims to standardize symmetric cryptographic designs, including authenticated encryption and hashing, suitable for constrained devices. One essential criterion for the evaluation of the 10 finalists is the evidence for their security against attacks like linear and differential cryptanalysis. For Ascon, one of the finalists and previous winner of the CAESAR competition in the ‘lightweight’ category, there is a large gap between the proven bounds and the best known characteristics found with heuristic tools: The bounds only cover up to 3 rounds with 15 differentially and 13 linearly active S-boxes, insufficient for proving a level of security for the full constructions.In this paper, we propose a new modeling strategy for SAT solvers and derive strong bounds for the round-reduced Ascon permutation. We prove that 4 rounds already ensure that any single characteristic has a differential probability or squared correlation of at most 2−72, and 6 rounds at most 2−108. This is significantly below the bound that could be exploited within the query limit for keyed Ascon modes. These bounds are probably not tight. To achieve this result, we propose a new search strategy of dividing the search space into a large number of subproblems based on ‘girdle patterns’, and show how to exploit the rotational symmetry of Ascon using necklace theory. Additionally, we evaluate and optimize several aspects of the pure SAT model, including the counter implementation and parallelizability, which we expect to be useful for future applications to other models.

Terminología marítima en el Lexicon, o Vocabulario de la lengua general del Perú de Domingo de Santo Tomás (1560) y posibles implicaciones para la historia de la familia lingüística quechua
Authors: Urban Matthias
Published: March 2022

Aunque el autor de la primera documentación gramatical y lexicográfica del quechua, Domingo de Santo Tomás, en ningún lugar de sus extensas obras menciona la base dialectal y geográfica de su trabajo, comúnmente se asume que se trata de un extinto dialecto quechua de la costa central del Perú. En esta contribución, reviso los argumentos en favor de la identificación dialectal y anoto algunos aspectos problemáticos que, aunque ya conocidos, merecen ser enfatizados. En este marco, ofrezco una discusión exhaustiva del Lexicon, o Vocabulario de la lengua general del Perú de Santo Tomás, específicamente del vocabulario relacionado con el mar. Sobre la base de la amplia documentación de expresiones pertenecientes al campo semántico marino (referencias al mar, la vida marina, los peces, la pesca, la náutica) que se encuentra en el Lexicon, o Vocabulario..., se puede derivar que el quechua descrito por Santo Tomás se había adaptado léxicamente a un ámbito costeño. Las propiedades de las expresiones relevantes, que con frecuencia parecen ser adaptaciones semánticas de palabras quechuas heredadas a este ámbito, o neologismos, o préstamos de otras lenguas costeñas, sugieren, sin embargo, que un porcentaje significativo del vocabulario fue adicionado relativamente tarde al fondo léxico. Esto, a su turno, es una prueba que avalaría la idea de que el dialecto costeño se originó fuera de la costa. Se discute la relevancia de esta observación en relación con teorías que sitúan la cuna de la familia lingüística quechua en la costa central, las cuales harían esperar un vocabulario marítimo con raíces más profundas en el léxico.
All in: Léxico ideológico del póker en línea
Authors: Peláez Torres Luis Carlos
Published: March 2022

El presente trabajo es una descripción semántico-lexicográfica del juego de apuestas conocido como póker, en la modalidad en línea. El objetivo de la investigación es ofrecer un léxico onomasiológico de los términos empleados por los usuarios de las aplicaciones de póker online sobre la base de la teoría de campos semánticos. En tal sentido, se emplea una metodología terminológica que consiste en agrupar las entradas léxicas en categorías hiperonímicas y holonímicas, de modo que se parte de un concepto para llegar al término hiponímico y meronímico, respectivamente. El análisis se ha realizado a partir de muestras léxicas tomadas de salas de póker online, de videotutoriales publicados por difusores y entusiastas del juego, así como de fuentes bibliográficas que las recogen (manuales y glosarios). De este modo, se recopila un corpus, se organizan los términos conceptualmente y se los define en función de siete campos semánticos: apuesta, expresión, dinero, jugada, jugador, mano, programa y turno, a fin de que puedan ser dispuestos en un soporte informático hipertextual.
El discurso monárquico en la «Loa al virrey Fernando de Abascal y Sousa» y otros poemas de José Joaquín de Olmedo
Authors: Zevallos Johnny
Published: March 2022

La poesía política escrita durante la crisis del sistema monárquico y la posterior independencia no ha merecido la atención suficiente de parte de la crítica literaria. Por ello, en este estudio, se analiza uno de los últimos ejemplos de poemas de circunstancias con motivo de la entrada del virrey Fernando de Abascal. El empleo de la mitología clásica y el aparato festivo que celebra al rey como pieza central del imperio son los motivos que resaltan en la primera producción del poeta guayaquileño José Joaquín de Olmedo. Cabe advertir, sin embargo, que, antes de la crisis política producida en la península en 1808, con motivo de la invasión napoleónica de España, arriban oficialmente los primeros ideales revolucionarios. Por ello, en este trabajo, se sostiene que estas producciones intentan legitimar la defensa del espacio imperial y la sostenibilidad del régimen en los primeros años del siglo xix. La construcción del discurso monárquico en la poesía de Olmedo consolida el papel de la ciudad letrada y del intelectual como agentes del discurso monárquico.
Penderitaan sebagai Ekspresi Kasih Karunia Yesus Kristus: Refleksi Teologi 1 Petrus 2:18-25

Suffering is a frightening specter for some people, so there are so many efforts made by some people to be free from what is called suffering, whether it is people who do not believe in Jesus Christ or who believe in Jesus Christ. Ironically, some people who believe in Jesus Christ often use the Bible by quoting a few verses in the Bible as reference to justify their arguments. In particular it relates to suffering without looking cohesive and comprehensive, so as to treat suffering as acurse. By denying all the data, arguments and facts that speak that the suffering of believers is not always  synonymous with curses but the suffering of believers is the grace of the Lord Jesus Christ. They suffer because of their faith and conviction in defending the truths taught and modeled by the Lord Jesus Christ.AbstrakPenderitaan adalah momok yang menakutkan bagi sebagian orang sehingga ada begitu banyak upaya yang dilakukan oleh sebagian orang untuk terbebas dari yang namanya penderitaan, baik itu orang yang tidak beriman kepada Yesus Kristus maupun orang yang beriman kepada Yesus Kristus. Ironisnya bagi sebagian orang yang percaya kepada Yesus Kristus seringkali menggunakan Alkitab dengan mengutip segelintir ayat dalam Alkitab sebagai referensi untuk membenarkan argumentasi mereka. Secara khusus berkaitan dengan penderitaan tanpa melihat secara kohesif dan kompreshensif, sehingga menyikapi segala penderitaan sebagai kutuk. Dengan menafikan segala data, dalil dan fakta yang berbicara bahwa penderitaan orang percaya tidak selalu identik dengan kutuk tetapi penderitaan orang percaya adalah kasih karunia Tuhan, Yesus Kristus. Mereka menderita karena iman dan keyakinan mereka di dalam mempertahankan kebenaran yang diajarkan dan diteladankan oleh Tuhan, Yesus Kristus.

The Potential for Liberation Feminism in Hindu Practices and its Patriarchal Origins
Authors: Didwania Naisha , Novak-Herzog Maya
Published: March 2022

Hinduism is accused of suppressing its women devotees, despite a history suggesting a matriarchal approach. Over the years, original knowledge surrounding religious practices have been lost due to misinterpretation, misinformation and autonomy over said knowledge by certain groups. The purpose of this essay is to explore the various practices that accuse Hinduism of being anti-feminist, and to identify their origins to understand the role that both culture and religious doctrine played in promoting women's inferiority, as well as which had greater influence. Previous research relies heavily on scriptural understanding and secondary data analysis, despite the fact that overreliance on scriptures is one of the major contributors to the spread of false information regarding the divorce between the intentions of the religious doctrine and subsequent traditions and customs. I interviewed practitioners of the religion coming from various backgrounds and used the primary data to theorise the origination of women's oppression and means to reduce its continuation. The understanding behind religious practices such as Sati, Pativrata and taboos surrounding female priesthood and menstruation yield results that attribute the patriarchy to factors that were not intrinsic to Hinduism. Hence, my findings conclude that women’s original knowledge of the fundamental tenets of Hinduism understood as anti-feminist facilitate their empowerment. Therefore, furthering original knowledge of ‘sexist ideals’ can increase the potential for liberation feminism for Hindu women by reducing the prevalence of conservative practices.

Los géneros discursivos y las secuencias didácticas: el lugar de los ejemplos prototípicos en la enseñanza y aprendizaje de la escritura
Authors: Abad Beltrán Victoria , Rodríguez Gonzalo Carmen
Published: March 2022

Desde una perspectiva social, el objetivo de la enseñanza de la escritura es facilitar que los alumnos sean capaces de comprender y redactar una gran diversidad de géneros discursivos, que les permita comportarse como ciudadanos reflexivos y críticos en distintos ámbitos sociales. En el proceso de dominio de cada género es clave la representación mental del texto, que actúa como elemento regulador de la escritura en sus distintas fases. Este artículo muestra las dificultades de los alumnos para apropiarse de un género determinado (una reseña de lectura), a partir de los datos de una investigación de aula con alumnos de 3º de ESO que aborda la escritura de reseñas mediante una secuencia didáctica que incluye, como elemento regulador, ejemplos prototípicos del género. El análisis de los datos de proceso (borradores e interacciones) y de producto (versión final de los textos) muestra que la enseñanza y el aprendizaje de la escritura se da en dos planos: un plano cuyo objetivo es crear una representación mental del texto y otro, orientado a enriquecer el texto con recursos lingüísticos puntuales.

Tweeting on Presidential Coattails: Congressional Candidate Use of Twitter in the 2020 Elections
Authors: Crawford Evan , Foehr Mikaela , Yee Nathaniel
Published: March 2022

There is a long history of political science research focused on congressional candidates riding presidential coattails into office. The underlying theory for this potential relationship is relatively simple—when presidential nominees are popular, they can help bolster the electoral fortunes of their down-ballot, co-partisan candidates. If this is right, congressional candidates should be incentivized to publicly align themselves with their co-partisan presidential nominee, albeit in strategic ways. We look for this relationship by constructing an original dataset of congressional candidate Twitter data and identifying the extent to which candidates mention presidential nominees during the 2020 campaign, a behavior we call “tweeting on coattails.” Our data allow us to describe relationships between “tweeting on coattails”, candidate party ID, and district-level electoral conditions. We find that overall, challengers tweeted more than incumbents, but incumbents were more likely to “tweet on coattails.” In addition, candidates of both parties “tweeted on coattails” more frequently if they were running in a district where their party’s nominee is popular. This relationship was not symmetric in magnitude, however, as Republicans were significantly more likely to tweet about Donald Trump than Democrats were to tweet about Joe Biden.
Advances in Vision Systems Will Enable Significant Improvements in Thread Metrology

Advances in Vision Systems Will Enable Significant Improvements in Thread Metrology. Visions systems have had a profound impact on manufacturing productivity and quality over the last decade. These optical/laser-based systems will continue to enhance the speed, productivity, cost and quality within a broad range of manufacturing processes globally. “The global machine vision market is estimated at $3.1 billion in 2012, and is expected to grow with a CAGR of 8.2 percent to $5.1 billion in 2018. The major factors driving the market are paradigm shifts in the global market demand for machine vision products, emergence of smart cameras ……” according to Market and Market, a global market research and consulting company. This article is intended to increase the reader’s awareness of advances in vision systems that will impact the manufacture and inspection of thread forms and thread gage calibration. These unique systems can be found in the metrology lab, shop floor, or in the field, providing enhanced speed, productivity, quality and cost for their users. Thread forms are of particular interest and importance to metrology and manufacturing/ quality professionals since they are a fundamental component that virtually holds our manufacturing world together. Thread forms are available in a wide variety of geometric shapes and industry standards. They are a principal method of fastening manufacturing components, and they form a critical component within a variety of industries like defense/aerospace, automotive, and energy. These thread forms can be simple, or eloquently complex. Nevertheless, the accuracy of their geometric shape is critical to the quality, reliability, and safety in many applications. The traditional methods for measuring and inspecting thread forms can be slow and costly, requiring skilled, experienced personnel. Vision systems will allow greater quality surveillance, lower costs, shorter cycle times, improved reliability/safety and overall productivity. We will examine two totally different types of vision system designs to provide non-contact, high-speed measurement and/or inspection of thread forms.
Result Summary of LED Bulb Interlaboratory Comparison in Taiwan
Authors:   CMS/ITRI, Fang Cheng-Yen
Published: March 2022

Interlaboratory comparison is organization, performance and evaluation of measurements or tests on the same or similar items by two or more laboratories in accordance with predetermined conditions, which is the way to demonstrate the measurement capability of each laboratory. In order to understand the LED bulb measurement capability of each laboratory in Taiwan, CMS/ITRI held a LED bulb interlaboratory comparison scheme. This activity can help the participants to understand the differences of their measurement capabilities compared with others and then seek the solution to improve their measurement competence. This LED bulb interlaboratory comparison scheme was carried out according to ISO/IEC 17043:2010. Percent difference |D%| was chosen as the performance statistic to indicate the measurement capabilities of participants, and the measured values of National Measurement Laboratory (NML), R.O.C. were used as the assigned values. From the analysis of this LED bulb interlaboratory comparison, most of participants’ results were satisfactory, which implied that most of LED bulb test laboratories in Taiwan have good measurement competence.
New 10V Programmable Josephson Voltage Standard (PJVS) and its Application for the 2014 NCSLI JVS Interlaboratory Comparison

Published: March 2022

The National Conference of Standard Laboratories International (NCSLI) is scheduled to start the 10th Josephson Voltage Standard (JVS) Interlaboratory Comparison (ILC) in early 2014. NASA’s Kennedy Space Center (KSC) which began operating a 10V Programmable Josephson Voltage Standard (PJVS) in 2010 is a pivot lab candidate for the NCSLI JVS ILC. We propose to use the NASA PJVS as a transfer standard for the intercomparison in addition to using the group of Zeners that were used in the previous ILC. The superior stability of the 10V PJVS’s voltage step enables it to perform the same tasks as the Zener standards and to also improve the efficiency and effectiveness of the ILC through a direct comparison. Recently, a comparison between a conventional JVS and the NIST 10V PJVS was performed by NIST in order to verify the performance of the NIST 10V PJVS. The mean difference between the two systems at 10V was found to be -0.49 nV with a combined standard uncertainty of 1.32 nV (k = 1) or a relative combined standard uncertainty of 1.32 parts in 1010. The advantage of using the 10V PJVS is that a participating lab is able to make comparisons using its conventional JVS system against the 10V PJVS in the same manner as the measurements for Zener standards are performed. Due to the quantum nature of the 10V PJVS, its superior accuracy and stability will improve the uncertainty of a JVS comparison for the direct comparison participants to a level of a few parts in 1010 at 10 V. This would be an improvement over the 2011 ILC which reported an expanded uncertainty with 95% confidence limits of +220 nV and -150 nV.
