This book was released on 2020-12-29 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2015 in the subject Computer Science - Applied, grade: 2, University of Applied Sciences Coburg, language: English, abstract: The project shall contribute to the further development of a prototypical implementation for an assistance solution supporting measurement uncertainty analysis within the existing framework. The main tasks in this project will be: Familiarisation with the topic of measurement uncertainty analysis and the handling of software GUM Workbench®, definition of an design outline for the user support during measurement uncertainty analysis, including an analysis of required supporting function and the subsequent definition of a possible system structure, selection of one aspect in the process and development of a draft for an adequate support solution, containing elements to enable partial automation or increase of efficiency for the process step as well as explanatory information for the users, prototypical implementation and testing of the defined elements within the outlined framework. In the "Guide to the Expression of Uncertainty in Measurement" (GUM), jointly issued by ISO and BIPM, a standard procedure for the determination of measurement uncertainty is defined. Yet, although this document is supported by many international organisations and the consideration of measurement uncertainty is of high importance in many fields of application, ranging from industrial quality control to scientific research, still often the determination of measurement uncertainty is omitted. This is mainly due to difficulties of the metrologists to apply the general rules of the GUM to the task at hand. To ease this task and support the determination of measurement uncertainty, the software GUM Workbench® performs all required mathematical evaluations based on a model of the measurement. Additionally, a concept for an assistance system as well as a graphic modelling editor has been developed to facilitate the definition of a suitable model. But, the existing concepts are not yet fit for practical testing under industrial conditions.
Download or read book Doubt Free Uncertainty In Measurement written by Colin P Ratcliffe and published by Springer. This book was released on 2014-11-21 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents measurement uncertainty and uncertainty budgets in a form accessible to practicing engineers and engineering students from across a wide range of disciplines. The book gives a detailed explanation of the methods presented by NIST in the “GUM” – Guide to Uncertainty of Measurement. Emphasis is placed on explaining the background and meaning of the topics, while keeping the level of mathematics at the minimum level necessary. Dr. Colin Ratcliffe, USNA, and Bridget Ratcliffe, Johns Hopkins, develop uncertainty budgets and explain their use. In some examples, the budget may show a process is already adequate and where costs can be saved. In other examples, the budget may show the process is inadequate and needs improvement. The book demonstrates how uncertainty budgets help identify the most cost effective place to make changes. In addition, an extensive fully-worked case study leads readers through all issues related to an uncertainty analysis, including a variety of different types of uncertainty budgets. The book is ideal for professional engineers and students concerned with a broad range of measurement assurance challenges in applied sciences. This book also: Facilitates practicing engineers’ understanding of uncertainty budgets, essential to calculating cost-effective savings to a wide variety of processes contingent on measurement Presents uncertainty budgets in an accessible style suitable for all undergraduate STEM courses that include a laboratory component Provides a highly adaptable supplement to graduate textbooks for courses where students’ work includes reporting on experimental results Includes an expanded case study developing uncertainty from transducers though measurands and propagated to the final measurement that can be used as a template for the analysis of many processes Stands as a useful pocket reference for all engineers and experimental scientists
Download or read book Measuring Uncertainty within the Theory of Evidence written by Simona Salicone and published by Springer. This book was released on 2018-04-23 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph considers the evaluation and expression of measurement uncertainty within the mathematical framework of the Theory of Evidence. With a new perspective on the metrology science, the text paves the way for innovative applications in a wide range of areas. Building on Simona Salicone’s Measurement Uncertainty: An Approach via the Mathematical Theory of Evidence, the material covers further developments of the Random Fuzzy Variable (RFV) approach to uncertainty and provides a more robust mathematical and metrological background to the combination of measurement results that leads to a more effective RFV combination method. While the first part of the book introduces measurement uncertainty, the Theory of Evidence, and fuzzy sets, the following parts bring together these concepts and derive an effective methodology for the evaluation and expression of measurement uncertainty. A supplementary downloadable program allows the readers to interact with the proposed approach by generating and combining RFVs through custom measurement functions. With numerous examples of applications, this book provides a comprehensive treatment of the RFV approach to uncertainty that is suitable for any graduate student or researcher with interests in the measurement field.

Download or read book Design Implementation and Analysis of an Algebra based Treatment of Measurement Uncertainty written by Ian Schanning and published by . This book was released on 2019 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learning to measure and propagate uncertainty is a necessity for understanding experimental data. But because statistics and calculus are required for a rigorous analysis of uncertainty, students in algebra-based physics classes are rarely able to determine the meaning of their experimental results. This thesis describes the design and implementation of an algebra-based method for calculating, propagating, and determining agreement with measurement uncertainty that was taught at scale to students of introductory physics for biologists. Changes to the previous lab implementation are described, including the additional of learning goals, in-class checkpoint questions, lab write-up prompts designed around uncertainty, and TA training. Student attitudes towards physics are measured in different instructional circumstances using the Colorado Learning About Science Survey. Several different methods of measuring how well the students learned the technique and the meaning of uncertainty are analyzed. Students showed more comfort and ability in using estimation and spread to determine ruler lengths after instruction. Students were more likely to use spread-based approaches in computer collected data. Students who performed the uncertainty propagation procedure were more likely (97% to 28%) use their calculated uncertainty in data comparisons. Different framings of uncertainty are compared. Since biology students also take lower division lab classes in chemistry, the complementary approach that each science takes in lab instruction is explored from a course design perspective and via student interviews.

Download or read book Measurement Uncertainty written by Simona Salicone and published by Springer. This book was released on 2010-11-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The expression of uncertainty in measurement poses a challenge since it involves physical, mathematical, and philosophical issues. This problem is intensified by the limitations of the probabilistic approach used by the current standard (the GUM Instrumentation Standard). This text presents an alternative approach. It makes full use of the mathematical theory of evidence to express the uncertainty in measurements. Coverage provides an overview of the current standard, then pinpoints and constructively resolves its limitations. Numerous examples throughout help explain the book’s unique approach.

Book excerpt: The Measuring Early Learning Quality and Outcomes (MELQO) initiative began in 2014 as part of the global emphasis on early childhood development (ECD). Led by UNESCO, the World Bank, the Center for Universal Education at the Brookings Institution and UNICEF, the initiative aims to promote feasible, accurate and useful measurement of childrenâs development and learning at the start of primary school, and of the quality of their pre-primary learning environments. Items are designed for children between the ages of 4 and 6 years. Following the premise that many existing tools include similar items, the leading organizationsâ core team worked with a consortium of experts, non-governmental organizations (NGOs) and multilaterals to build upon current measurement tools to create a common set of items organized into modules for measuring: 1) early childhood development and learning, and 2) the quality of pre-primary learning environments. The MELQO core team and experts also collaborated to outline a process for context-specific adaptation of the measurement modules resulting from lessons learned from field-testing in several countries in 2015 and 2016. The modules are designed to be implemented at scale, with an emphasis on feasibility for low- and middle-income countries (LMICs). A key question addressed by MELQO was the balance between a global tool suitable for use everywhere, and local priorities and goals for childrenâs development. [Introduction, ed]
