Measurement and Instrumentation: An Introduction to Concepts and Methods - 1st Edition

Contributors: Dyer and Davis

Publisher: SHAREOK

Measurement and instrumentation are fundamental elements of many engineering projects. From research, to development, to manufacturing, to user products, engineers are constantly needing to measure things: brightness of a light, dimensions of an object, separation between things, frequency content, stress, strain, pressure, voltage, etc. In the real world measuring systems are not perfect, so the results of a measurement are only an estimate of the true value. Instrumentation for making measurements relies on some fundamental assumptions to ensure the veracity of the measurements. Some key elements are: bandwidth, sampling rate, dynamic range, sensor type, etc. This text discusses the basic concepts of what a measurement is, how the instrumentation chosen (or developed) can affect the measurement, and how to deal with the measurement error that is in all instrumentation systems. Topics include data acquisition, signal conditioning, sensor types, and measurement noise and its various noise distributions. The text concludes with three user projects that bring together these topics into an informative work that reinforces the theory.

Electromechanical Systems - 1st Edition

Contributor: Davis

Publisher: SHAREOK

License: CC BY-NC-SA

This eBook was written as the third installment in the series that coincide with three engineering courses taught at the University of Oklahoma (ENGR 2431, ENGR 2531, and ENGR 3431). These courses were designed to provide non-major students – those not majoring in electrical or computer engineering (ECE) – a foundation in various ECE topics. ENGR 2431 is a prerequisite for both ENGR 2531 and ENGR 3431 and it is recommended that the DC Circuits book be studied prior to beginning the eBooks created for the other two courses. The following topics are covered in this book: LabVIEW Overview Module 1 – Number Systems and Character Encoding Module 2 – Digital Logic Module 3 – Measurement and Instrumentation Overview Module 4 – Sensors Module 5 – Power Systems Module 6 – Electric Machines Module 7 – Computer Communications Appendix A – Step by Step Guide to Digital, Analog, and Counter IOs in a DAQ

Testing theory: an introduction

Contributor: Teunissen

Publisher: TU Delft Open

These lecture notes are a follow up on Adjustment theory. Adjustment theory deals with the optimal combination of redundant measurements together with the estimation of unknown parameters. There are two main reasons for performing redundant measurements. First, the wish to increase the accuracy of the results computed. Second, the requirement to be able to check for mistakes or errors. The present book addresses this second topic. Although one always will try one's best to avoid making mistakes, they can and will occasionally happen. It is therefore of importance to have ways of detecting and identifying such mistakes. Mistakes or errors can come in many different guises. They could be caused by mistakes made by the observer, or by the fact that defective instruments are used, or by wrong assumptions about the functional relations between the observables. When passed unnoticed, these errors will deteriorate the final results.

Adjustment theory: an introduction

Contributor: Teunissen

Publisher: TU Delft Open

License: CC BY

Adjustment theory can be regarded as the part of mathematical geodesy that deals with the optimal combination of redundant measurements together with the estimation of unknown parameters. It is essential for a geodesist, its meaning comparable to what mechanics means to a civil engineer or a mechanical engineer. Historically, the first methods of combining redundant measurements originate from the study of three problems in geodesy and astronomy, namely to determine the size and shape of the Earth, to explain the long-term inequality in the motions of Jupiter and Saturn, and to find a mathematical representation of the motions of the Moon. Nowadays, the methods of adjustment are used for a much greater variety of geodetic applications, ranging from, for instance, surveying and navigation to remote sensing and global positioning.

This book focuses on the cost planning of building construction projects with special reference to the Australian and New Zealand context. Design development and cost planning with elemental analysis are emphasised in the pre-construction cost management process in the region. This book translates the well-established practice of pre-construction cost management process in the construction industry into a published academic and professional resource which can be used for teaching higher education students and for professional training programs.

Building User Interfaces for Modern Web Applications: React Programming

Contributor: Yang

Publisher: The Pennsylvania Alliance for Design of Open Textbooks (PA-ADOPT)

License: CC BY-NC

Since Facebook released React as an open-source software library for front-end programming in 2013, React has gain popularity quickly. Although there are other frameworks or libraries, React is considered a programmer-friendly JavaScript library using the functional programming approach for the front-end web application development. Teaching and learning React can provide training in Functional Programming, Software Engineering Principles, and the Event-Driven Programming Paradigm. The ultimate goal of this eTextbook is to provide a timely support for teaching the state-of-the-art technology as the React ecosystem evolves.

From theORy to application: learning to optimize with Operations Research in an interactive way

Contributors: Bombelli, Atasoy, Fazi, and Boschma

Publisher: TU Delft Open

License: CC BY

This book serves as a comprehensive roadmap for navigating the realm of Operations Research (OR). From laying down fundamental mathematical principles to crafting precise modeling techniques and their solution methods, it culminates in a panoramic view of OR models mirroring real-world operations. Delving into diverse applications-from assignment problems to network problems like graph coloring and minimum spanning trees, and navigating through routing problems that are very common in logistics-the book equips readers with practical insights. Each model is accompanied by meticulously detailed examples, seamlessly integrated with hyperlinked codes accessible via an open repository. Moreover, it introduces an engaging dimension with hyperlinks to three serious games replicating some cornerstone OR models, offering a playful yet educational environment for solo or group experimentation.

Electrolysers, Fuel Cells and Batteries: Analytical Modelling

Contributor: Haverkort

Publisher: TU Delft Open

License: CC BY

Electrochemical engineering deals with electrochemical devices like electrolysers, fuel cells, and batteries. While several excellent books exist in this long-standing and still growing field, their focus is usually on chemistry or phenomenology. In this textbook, we focus on mathematical modelling of the physical phenomena involved. Instead of resorting to numerical modelling, the aim is to derive simplified analytical models that maximise understanding. Porous electrodes, ion mass transport, and multiphase flow are central themes in this book. Examples include modelling the water saturation in a fuel cell diffusion layer, the gas fraction and current distribution in an alkaline water electrolyser, the potential distribution in a binary electrolyte inside porous battery electrode, and the concentration distribution in the flow channel of a redox flow battery. This makes for a diverse, challenging, and stimulating journey, for both students and researchers.
