Thermal and structural electronic packaging analysis for space and extreme environments
\"Have you ever wondered how NASA designs, builds, and tests spacecrafts and hardware for space? How is it that wildly successful programs such as the Mars Exploration Rovers could produce a rover that lasted over ten times the expected prime mission duration? Or build a spacecraft designed to visit two orbiting destinations and last over 10 years when the fuel ran out? This book was written by NASA/JPL engineers with experience across multiple projects, including the Mars rovers, Mars helicopter, and Dawn ion propulsion spacecraft in addition to many more missions and technology demonstration programs. It provides useful and practical approaches to solving the most complex thermal-structural problems ever attempted for design spacecraft to survive the severe cold of deep space, as well as the unforgiving temperature swings on the surface of Mars. This is done without losing sight of the fundamental and classical theories of thermodynamics and structural mechanics that paved the way to more pragmatic and applied methods such finite element analysis and Monte Carlo ray tracing, for example. Features: Includes case studies from NASA's Jet Propulsion Laboratory, which prides itself in robotic exploration of the solar system, as well as flyting the first cubeSAT to Mars. Enables spacecraft designer engineers to create a design that is structurally and thermally sound, and reliable, in the quickest time afforded. Examines innovative low-cost thermal and power systems. Explains how to design to survive rocket launch, the surfaces of Mars and Venus. Suitable for practicing professionals as well as upper-level students in the areas of aerospace, mechanical, thermal, electrical, and systems engineering, Thermal and Structural Electronic Packaging Analysis for Space and Extreme Environments provides cutting-edge information on how to design, and analyze, and test in the fast-paced and low-cost small satellite environment and learn techniques to reduce the design and test cycles without compromising reliability. It serves both as a reference and a training manual for designing satellites to withstand the structural and thermal challenges of extreme environments in outer space\"-- Provided by publisher.

Voting Technology: The Not-So-Simple Act of Casting a Ballot
Evaluates five commercially available voting systems, against different criteria (including ease of use, speed, and accuracy) using field and laboratory experiments and expert reviews. Initiates new research into interactions between ballot format and voter behavior. Offers best practices for voting system manufacturers, ballot designers, election officials, political observers, and voters
eBook
Reliability Technology
A unique book that describes the practical processes necessary to achieve failure free equipment performance, for quality and reliability engineers, design, manufacturing process and environmental test engineers.
This book studies the essential requirements for successful product life cycle management. It identifies key contributors to failure in product life cycle management and particular emphasis is placed upon the importance of thorough Manufacturing Process Capability reviews for both in-house and outsourced manufacturing strategies. The readers? attention is also drawn to the many hazards to which a new product is exposed from the commencement of manufacture through to end of life disposal.
* Revolutionary in focus, as it describes how to achieve failure free performance rather than how to predict an acceptable performance failure rate (reliability technology rather than reliability engineering)
* Author has over 40 years experience in the field, and the text is based on classroom tested notes from the reliability technology course he taught at Massachusetts Institute of Technology (MIT), USA
* Contains graphical interpretations of mathematical models together with diagrams, tables of physical constants, case studies and unique worked examples

Electronic elections
Since the 2000 presidential election, the United States has been embroiled in debates about electronic voting. Critics say the new technologies invite tampering and fraud. Advocates say they enhance the accuracy of vote counts and make casting ballots easier--and ultimately foster greater political participation.Electronic Electionscuts through the media spin to assess the advantages and risks associated with different ways of casting ballots--and shows how e-voting can be the future of American democracy.
Elections by nature are fraught with risk. Michael Alvarez and Thad Hall fully examine the range of past methods and the new technologies that have been created to try to minimize risk and accurately reflect the will of voters. Drawing upon a wealth of new data on how different kinds of electronic voting machines have performed in recent elections nationwide, they evaluate the security issues that have been the subject of so much media attention, and examine the impacts the new computer-based solutions is having on voter participation. Alvarez and Hall explain why the benefits of e-voting can outweigh the challenges, and they argue that media coverage of the new technologies has emphasized their problems while virtually ignoring their enormous potential for empowering more citizens to vote. The authors also offer ways to improve voting technologies and to develop more effective means of implementing and evaluating these systems.
Electronic Electionsmakes a case for how e-voting can work in the United States, showing why making it work right is essential to the future vibrancy of the democratic process.
