Exploring the Impact of Teaching Metrology in Manufacturing Processes in Mexico
Authors:   Universidad Aeronáutica en Querétaro, Mexico, Herrera-Basurto Raul
Published: March 2022

The technologies of materials production with applications in various fields including food, automotive and aerospace, have begun to settle in several clusters in Mexico. Some examples of this type of manufacturing processes are adhesive, additive, thermal projection and nanotechnology. On the other hand, the implementation of the concept of industry 4.0 has brought a new way of organizing the production ways. This has generated a demand of qualified personnel with the ability to identify elements that help to provide quality criteria for lots of pieces or single pieces manufactured under the processes described above. personnel must comply the following competencies: knowledge in manufacturing process, testing and metrology. In Querétaro, México universities such as Universidad Politécnica de Santa Rosa Jáuregui (UPSRJ) and Universidad Aeronáutica en Querétaro (UNAQ) have implemented a strategy to meet this needs. This strategy includes the teaching of courses related to metrology, standardization and conformity assessment applied to the manufacturing processes. UPSRJ has a bachelor degree in Industrial Metrology Engineering, where students can have a specialized educational program in the science of measurements. While at UNAQ students can have selected measurement courses for aerospace sciences as part of the aerospace engineering master program, according to the requirements of NADCAP. A relevant situation is that several graduates of both institutions are already working in the industry in charged of the quality of manufacturing processes. These graduates already understand the importance of using the uncertainty and sensitivity of the measurements as innovative parameters for the continuous improvement of manufacturing processes.

Authors:   The Standards and Calibration Laboratory, Wah LAI Terry Hau ,   The Government of the Hong Kong Special  Administrative Region
Published: March 2022

This paper demonstrates the essential procedures in the Hong Kong Standards and Calibration Laboratory for the calibration of an electrostatic discharge (ESD) generator in accordance with the International Standard IEC 61000-4-2 Edition 2.0 (2008-12) of electromagnetic compatibility. All the required instruments and special precautions to perform the calibration are listed clearly. The performance of an ESD generator has been tested and reported by following the requirement of the standard. The corresponding results, including the waveform parameters of the current discharge pulse and the DC high voltage test of the ESD generator before discharge with different voltages setting, are reported. The measurement uncertainties of the calibration are clearly listed in this paper, and they are evaluated in accordance with the document "Guide to the Expression of Uncertainty in Measurement (GUM)". The expanded measurement uncertainty U, with level of confidence of approximate 95 %probability is used in the calibration.
Best Lessons Learned from FDA Warning Letters
Authors:   Medtronic, Nowocin Walter
Published: March 2022

Over the past five years, the U.S. Food & Drug Administration (FDA) has intensified their compliance oversight with increased Quality System Surveillance Inspections and increased Warning Letters being sent to Healthcare companies. Warning Letters are issued only for violations of regulatory significance. The good news is that the FDA publishes all Warning Letters on their web site as a public service. And they have a very easy search engine that allows you to find Warning Letters that contain topics particular to your industry or job. This paper reviews calibration related FDA Warning Letters generated over the past five years to select the best ten examples. We will analyze the best Warning Letter examples and discuss best practices that would avoid these violations. With this knowledge, we can learn from these violations and ensure that our metrology programs do not negatively impact the cost of quality of our organizations.
Logical And Cost Effective Calibration Intervals
Authors:   Tektronix, Roach Tyler
Published: March 2022

Periodic calibration does not prevent out-of-tolerances from occurring, but with a well-managed recall program, the risk can be minimized. Managing calibration recall intervals can be a perplexing task and sometimes seem somewhat arbitrary. Do I use the manufacturer's recommended interval? Do I use the ever so popular, yet arbitrary 12-month interval? Or, do I just use the interval that was used last time my unit was calibrated? Selecting an interval that is too long could save on excessive calibration costs, however it could also introduce the additional unwanted risk of using an out of tolerance item. An interval that is too short would eliminate that risk, but calibration costs will rise. The goal is to have the perfect Goldilocks situation to find an interval that is just right. One that will reduce calibration costs, yet still give you confidence that it will still be in-tolerance at the next calibration event. A simple examination of past calibration history, combined with a few strategic confidence checks will make managing recall intervals logical and cost effective.
Calibration of the Frame Rate of High Speed Digital Video Recorders by Stationary Counting Method: Application of the Stroboscopic Effect
Authors:   The Standards and Calibration Laboratory, Hau Wah LAI Terry
Published: March 2022

By applying the characteristic of stroboscopic effect, a new method named Stationary Counting Method for the calibration of the frame rate of digital video recorder has been developed at the Hong Kong Standards and Calibration Laboratory(SCL). The proposed method can determine the frame rate of digital video recorders with the use of a special synchronous counter designed by the SCL. The frequency signal input to the counter is traceable to the Cesium Beam Frequency Standard kept in SCL, as well as traceable to the SI unit. The target devices include high speed digital cameras, smartphones, closed circuit televisions (CCTV) and car cameras. It is common for vehicles to install car cameras to capture the moment when unexpected incidents occur. The recorded videos can be used as court evidences for accident investigation. Therefore, the accuracy of the frame rate is extremely important. The proposed method can be used to find the time duration of the video recorded by a digital camera, as well as the occurrence of skipped or extra frames of the captured video.

Published: March 2022

Abstract. Validation of remote sensing retrievals of aerosol microphysical and optical properties requires in situ measurements of the same properties. We present here an improved imaging nephelometer for measuring the directionality and polarization of light (i.e., polarimetry) scattered at two wavelengths (405 and 660 nm) with high temporal resolution. The
instrument was designed for airborne deployment and is capable of
ground-based measurements as well. The laser imaging nephelometer (LiNeph)
uses two orthogonal detectors with wide-angle lenses and linearly polarized
light sources to measure both the phase function, P11(θ), and
degree of linear polarization, -P12/P11(θ). In this work,
we will describe the instrument function and calibration, as well as data
acquisition and reduction. The instrument was first deployed aboard the NASA DC-8 during the 2019 FIREX-AQ campaign. Here, we present field measurements of smoke plumes that show that the LiNeph has sufficient resolution for 0.24 Hz polarimetric measurements at two wavelengths, 405 and 660 nm, at integrated scattering coefficients ranging from 50–8000 Mm−1.

Abstract. Periods of high atmospheric CO2 levels during the Cretaceous–early Paleogene (∼ 140 to 34 Myr ago) were marked by very high
polar temperatures and reduced latitudinal gradients relative to the Holocene. These features represent a challenge for most climate models,
implying either higher-than-predicted climate sensitivity to atmospheric CO2 or systematic biases or misinterpretations in proxy
data. Here, we present a reconstruction of marine temperatures at polar (> 80∘) and middle (∼ 40∘) paleolatitudes during the
Early Jurassic (∼ 180 Myr ago) based on the clumped isotope (Δ47) and oxygen isotope (δ18Oc) analyses
of shallow buried pristine mollusc shells. Reconstructed calcification temperatures range from ∼ 8 to ∼ 18 ∘C in the
Toarcian Arctic and from ∼ 24 to ∼ 28 ∘C in Pliensbachian mid-paleolatitudes. These polar temperatures were
∼ 10–20 ∘C higher than present along with reduced latitudinal gradients. Reconstructed seawater oxygen isotope values
(δ18Ow) of −1.5 ‰ to 0.5 ‰ VSMOW and of −5 ‰ to −2.5 ‰ VSMOW at middle and polar
paleolatitudes, respectively, point to a significant freshwater contribution in Arctic regions. These data highlight the risk of assuming the same
δ18Osw value for δ18O-derived temperature from different oceanic regions. These findings provide critical new
constraints for model simulations of Jurassic temperatures and δ18Osw values and suggest that high climate sensitivity has been a
hallmark of greenhouse climates for at least 180 Myr.

What happens when a diverse group of youth ages 11 through 14 are introduced to data science using authentic, public, multivariate data in an out-of-school context assuming no special prerequisite knowledge? We designed three 10-hour Data Club modules in which real-world data and the questions students asked of such data drove the learning process. Each module was grounded in a topic that youth connected with at a personal level. Youth learned how to use a free online data platform that made it easy to rearrange, group, filter, and graph data. Within the progression of the module, we used youths’ own questions, data moves, and data visualizations to engage them in critical inquiry and foster productive habits of mind for working with data. Our goal was for youth to emerge from the Data Clubs experience feeling empowered to interact with, ask questions of, and reason about and from data.

Published: March 2022

Through the “COVID-Inspired Data Science through Epidemiology Education” project, 400 underserved middle-school youth across the United States are engaging in a 20-hour out-of-school data club centered on a novel. The narrative is integrated with hands-on data activities and modeling (e.g., creating graphs of infections over time in CODAP; modeling disease transmission rates in NetLogo). Youth learn to: 1) Use data tools to track the spread of a variety of infectious diseases; 2) Ask and address their own questions of data; and 3) Use data to communicate to local audiences about epidemiological patterns and challenges. The project breaks new ground in integrating data science with epidemiology education for 11–14-year-old youth.

Big data is a welcomed addition to the conventional field of the Sciences, coming at a time of increased volumes, having additional collection methods, diverse ways of manipulating and processing data using a variety of tools for undertaking analyses, graphical representation, and dissemination. New experiences confronting the global environment serve to widen the scope of pedagogy enhancing mode of delivery and giving many dimensions to data culture. In the context of COVID-19, the extensiveness of its impact is indicative of far-reaching consequences and data requirement in order to understand and deal with the difficulties that have come about. In this paper, we demonstrate how practical applications of statistical procedures, as applied to the COVID-19 pandemic, can improve teaching and learning in a graduate Economics programme in the Caribbean. The paper provides some possibilities for syllabus construction to better prepare students of Economics for the world of research, academia and policy making using relevant data.

Published: March 2022

With data exponentially growing lately, data literacy has become essential for individuals and organizations to prosper. Nonetheless, it is rare and seems an unattainable goal to the majority of people. Researchers, policymakers, and educators are exploring ways of getting learners excited about data, and the Leuphana University of Luneburg is not left behind in this quest. Starting in the winter semester of 2021/2022, all 1,450 first-year students will undergo basic data literacy education at Leuphana, which includes the teaching of related knowledge and skills as well as relevant ethical issues. In this paper, we theoretically explore how to design teaching-learning settings that, given heterogeneous learning groups, can transform initially unmotivated students into intrinsically motivated lifelong learners of data competencies. Furthermore, in light of our empirical experience, we derive and discuss design principles that will enable readers to find a context-adapted solution.

Published: March 2022

Students are not aware and have little understanding of collecting and processing personal data in their everyday contexts of interaction with data-driven digital artifacts. To be aware of where, how and why data are collected and processed is important to be self-determined. Therefore, we develop and evaluate a teaching sequence to provide reasoning about data as a fundamental aspect of statistical literacy. This teaching sequences deals with the context of interaction with a cellular network where location data are collected. Students get real location data from an unknown person which can be explored with the aim to characterize the person. Students gain different insights by using different basic filters and explain how they achieve these. The results of the exploratory study indicate that students learned to gain insights by exploring given location data and that these insights may describe the person with detailed aspects that may not necessarily be true.

The Strengthening Data Literacy across the Curriculum (SDLC) project has been developing and researching curriculum modules to build interest and skills in data science among U.S. high school students from historically marginalized groups. SDLC modules are centered on investigations of social justice questions using large-scale social science data and the Common Online Data Analysis Platform (CODAP). This paper examines the extent to which students show increased interest in statistics and data analysis, and stronger understanding of core statistical concepts and multivariable thinking, after completing a three-week SDLC module. This paper also discusses ways in which a social justice focus may contribute to students’ interests in and understanding of data analysis.
Simulation as a tool to make sense of the world
Authors: Burrill Gail
Published: March 2022

An educational goal should be to prepare all students, not just those mathematically disposed, to make sound statistical inferences in different contexts. Students should be able to make decisions in the presence of uncertainty and to interpret quantitative information presented to them in the course of their professional and personal lives. This paper highlights terms such as herd immunity or efficacy that have emerged in the popular media since the onset of the COVID-19 pandemic and connects them to activities involving statistics and mathematics. Examples illustrate how simulation can be a vehicle for developing understanding of statistical concepts related to the pandemic and how simulation can engage students in reasoning from data to make sense of the world in which we live.

Published: March 2022

The concept of a probability distribution is in the core of all modern data-driven modeling, simulation, analytics, inference, prediction, and prognostication of observable natural phenomena. Despite the large number of possible probability distributions and their significant heterogeneity, only dozens of distributions are named and well understood, many are interconnected, and all of them span the universe of all possible physical processes. This manuscript presents the probability Distributome, which allows navigation, exploration and learning of many univariate distributions, and facilitate the computation and visualization associated with univariate, bivariate and trivariate probability distributions. We illustrate applications of three specific resources including an HTML5/JavaScript applications (http://Distributome.org), RShiny apps (https://socr.umich.edu/html/dist) and 2D and 3D Plotly apps (https://socr.umich.edu/HTML5/BivariateNormal/BVN2/). These resources are freely accessible, open-source, and platform agnostic. Both learners and instructors may utilize, expand, improve, and customize these tools for their specific research and education needs.
The challenge of hybrid teaching for the internship programme
Authors: Terán Teresita E.
Published: March 2022

Teacher Internship, obligatory in many Teaching School programmes, is that part of pre-service education for teacher-students that provides a practice for learning to teach a subject in an actual class. This paper reports the measurements that have been implemented to organize a hybrid form of a Statistics Teaching Internship programme for the teacher students at our university, during 2020. We present some of our actions to meet this challenge, as not even virtual teaching in high schools was possible at all levels. For the schools where the students have not access to computers or internet, the interns had to develop course booklets with tasks, which were collected and corrected. For the university-teaching part, the courses were delivered virtually and filmed so that they could be analysed. The analysis aims at identifying face-to-face amendments so that a hybrid approach can be developed.
Data and Statistics as basis for political decisions: lessons to be learnt from the COVID-19 pandemic
Authors:   Ludwigsburg University of Education, Germany, Engel Joachim , Wilhelm Adalbert ,   Jacobs University Bremen, Germany
Published: March 2022

The Covid-19 crisis has impressively raised the general awareness that our social coexistence and political decisions are essentially based on data, the weighing of risks and thus on probability estimates. This places high demands on the ability of health authorities, policy makers and the media to communicate statistical information as well as on the ability of citizens to understand these messages. In this paper we reflect on the role of scientific evidence in democratic societies and analyze selected illustrative examples of communicating evidence via visualizations and simulation, media reports, and expert’s statements. We identify venues and formats of communicating statistical information about the pandemics to the public that seems to be effective contrasting less helpful formats. We conclude by presenting recommendations for stakeholders in politics, media and statistics agencies on how to communicate empirical evidence to the public efficiently, released by the Deutsche Arbeitsgemeinschaft Statistik, an umbrella organization of statistical associations in Germany.
Captions: The Unsung Heroes of Data Communication
Authors:   Bucknell University, Stoudt Sara , Nolan Deborah ,   University of California, Berkeley
Published: March 2022

Data visualization has been recognized as an important tool in communicating data-related findings. Figures often contain a dense amount of information and readers rely on accompanying text to help guide them to the important takeaways. Captions provide the reader with the context needed to interpret visualizations and help tie together the written and visual narratives. Alt-text also plays a role in making the visualization accessible to a broader audience, translating visual cues for those with visual impairments. However, the art of writing captions and other accompanying text for visualizations has rarely been explicitly taught as a companion to the pedagogy of effective data visualization. We describe a variety of classroom activities and assignments that explicitly focus on what makes an effective caption, interpreted broadly, and that build awareness for a variety of audiences for data-related findings.

We are in the age of “Big Data” where only few can do their work effectively without performing some sort of quantitative analysis or referring to empirical information. With the introductory statistics course being the main source of quantitative training for undergraduates, efforts should focus on designing introductory statistics to promote data literacy and help students develop statistical reasoning and acquire the data-analytical skills essential for the Data Science era. Such efforts should be particularly supported at minority serving institutions to help with closing the diversity gap in Statistics and Data Science. This study uses extensive students’ data from a large minority serving institution in the United States to show the consequences of the consensus (traditional) introductory statistics course design on students’ learning gains and experience, and to explore the potential of introductory statistics to promote data literacy and attract minority students to pursue Data Science education and/or careers.

Identification is the feeling of experiencing the success and failure of the organization as if it is their own, and the individual's perception of himself as a whole with the organization. A teacher's feeling of belonging to the school, perceiving the success of the school as his own success, feeling himself as a whole with his school indicate that the teacher identifies with the school. The role of teachers' identification with their organizations in their self-sacrificing and self-sacrificing performance is undeniable. Teachers have a very important role in supporting the individual development of students, directing them correctly in peer relations or undesirable behaviors, raising them as independent individuals and evaluating the learning environment in the most efficient way.

In this paper, we present a new k-fractional integral oper-ators involving
parameters γ, λ analogous to the Riemann-Liouville k-fractional integral. This new
fractional integral operators dependent on an exponential function of arbitrary exponent in
the kernel of the integral. We prove, certain basic properties such as semi group property,
commu-tative law and boundedness for new fractional integral operators. Also, we discuss
Chebyshev type inequalities and some k-fractional integral in-equalities corresponding to
the new k-fractional integral operators

Demand for eco-friendly materials increases each year due to their excellent properties, which has proved to contribute to developing a sustainable environment. One of the promising raw materials in producing Glass is rice husk, a waste product from paddy harvesting, containing about 90% of silica. Rice husks are usually burnt in an open area and contribute to severe air pollution problems. In this research, Soda-Lime-Silica Rice Husk Ash (SLRHA) glass which is a new combination of soda-lime silicate (SLS) glass and rice husk ash (RHA), was developed for building glass and window application. The hardness properties of the developed SLS-RHA glass system are presented in this paper. These glasses were investigated to determine the effect of RHA addition on the physical properties of SLS glass. The experimental works using RSM have successfully identified the significant factors and optimized the responses. Based on the Rockwell hardness test, the outcomes demonstrated that the glass sample contained 29.84% weight SLS and 0.06% weight RHA. The result indicated that crack propagation was increased with the increasing addition of RHA, which causes an increase in cracks and voids due to the creation of more debonding.

Nowadays, with increased demand for aggregates for concrete and an awareness of the need of protecting natural resources, experts are becoming increasingly interested in waste material as a building material substitute. However, the compressive strength is influenced by the composition of concrete. In this study, the compressive strength of concrete under substitution using waste from cockle shells and glass was investigated using Response Surface Methodology (RSM). Central Composite Design (CCD) based on RSM was used to assess the influence of epoxy resin, cockle shells powder, and glass powder on compressive strength responses. RSM developed first-order and second-order mathematical models with findings from experimental design. Analysis of variance was used to determine the correctness of CCD's mathematical models. Desirability analysis was then employed to optimize epoxy resin, cockle shells powder, and glass powder yielding maximum compressive strength. The RSM analysis revealed that the empirical results fit well into linear and quadratic models of concrete compressive strength. The mixing components will produce cement with compressive strength in each formulation of 54.71 MPa (4.88% epoxy resin and 4.0% cockle shells powder), 47.82 MPa (6.85% epoxy resin and 8.0% glass powder), 147.0 MPa, (4% cockle shells powder and 8% glass powder), and 56.08 MPa (4.4% epoxy resin, 4.0% cockle shells powder, and 8.0% glass powder). The results confirmed that a reasonable compressive strength of concrete could be achieved using epoxy resin, cockle shells powder, and glass powder.

At present, the problem of storing large data sets as a source of artificial intelligence acquires a geopolitical and strategic character. The most well-known and used type of databases so far are the relational (SQL databases) and nonrelational (NoSQL databases. The both approaches have some principle problems, which are described below. That publication presents two original approaches to overcoming some of these shortcomings. First one is Object-oriented model for storing data in a relational database. The second is Storage of non-relational data in a relational database according to previously freely created by the user models. Presented models were used as base for software development of more than ten middle and large size national and European scientific and industrial projects.

Published: March 2022

The methods of linear optimization are well-known, both in the literature and practice, as one of the most effective methods for optimizing economic phenomena and processes. Linear models with determined coefficients have been thoroughly studied so far, but there are still areas in which research related to parametric linear optimization models can be further developed and improved. In the present paper, the graphical method for solving a two-factor linear optimization problem is used to analyze the solution of a problem for optimal distribution of resources with two parameters in the coefficients multiplying the variables in one of the constraints.
