Testing Complex and Embedded Systems
by Kim H. Pries Jon M. QuigleyMany enterprises regard system-level testing as the final piece of the development effort, rather than as a tool that should be integrated throughout the development process. As a consequence, test teams often execute critical test plans just before product launch, resulting in much of the corrective work being performed in a rush and at the last minute. Presenting combinatorial approaches for improving test coverage, Testing Complex and Embedded Systems details techniques to help you streamline testing and identify problems before they occur—including turbocharged testing using Six Sigma and exploratory testing methods. Rather than present the continuum of testing for particular products or design attributes, the text focuses on boundary conditions. Examining systems and software testing, it explains how to use simulation and emulation to complement testing. Details how to manage multiple test hardware and software deliveries Examines the contradictory perspectives of testing—including ordered/ random, structured /unstructured, bench/field, and repeatable/non repeatable Covers essential planning activities prior to testing, how to scope the work, and how to reach a successful conclusion Explains how to determine when testing is complete Where you find organizations that are successful at product development, you are likely to find groups that practice disciplined, strategic, and thorough testing. Tapping into the authors’ decades of experience managing test groups in the automotive industry, this book provides the understanding to help ensure your organization joins the likes of these groups.

Testing Explanations of Short Baseline Neutrino Anomalies (Springer Theses)
by Nicolò FoppianiThis thesis, encompassing both theory to experiment, guides the reader in a pedagogical way through the author’s attempts to resolve the mystery of the so-called MiniBooNE anomaly, where unexpected neutrino oscillations were reported, potentially explainable by the existence of light sterile neutrinos, but in contradiction with several null results. Within this context, this thesis reports one of the first analyses searching for an excess of electrons in the MicroBooNE experiment finding no excess of events and narrowing down the possible explanations for the anomaly. Additionally, this thesis explores non-minimal heavy neutral leptons as potential explanations for the MiniBooNE excess. To search for evidence for this particle, the author performs an analysis using data from the T2K experiment, which searched for pairs of electrons using a gas argon time projection. This thesis provides a comprehensive explanation of the MiniBooNE anomaly and test of its possibile explanation with liquid and gas time projection chambers.

The book also addresses testing for small-delay defects (SDDs), which can cause immediate timing failures on both critical and non-critical paths in the circuit. Overviews semiconductor industry test challenges and the need for SDD testing, including basic concepts and introductory material Describes algorithmic solutions incorporated in commercial tools from Mentor Graphics Reviews SDD testing based on "alternative methods" that explores new metrics, top-off ATPG, and circuit topology-based solutions Highlights the advantages and disadvantages of a diverse set of metrics, and identifies scope for improvement Written from the triple viewpoint of university researchers, EDA tool developers, and chip designers and tool users, this book is the first of its kind to address all aspects of SDD testing from such a diverse perspective. The book is designed as a one-stop reference for current industrial practices, research challenges in the domain of SDD testing, and recent developments in SDD solutions.
Testing Molecular Wires
by Mateusz WielopolskiThe field of molecular electronics and organic photovoltaics is steadily growing. One of the major themes in molecular electronics is the construction, measurement, and understanding of the current-voltage response of an electronic circuit, in which molecules may act as conducting elements. The investigated molecular structures in this thesis have been shown to be suitable for distance-independent charge transport. More precisely, the systems investigated were of particular interest due to their ability to provide efficient electronic coupling between electroactive units, and display wire-like behavior in terms of transferring charges from donors to acceptors. Besides impacting on the field of molecular electronics, the results of this research also has applications in the design and development of light harvesting, photoconversion and catalytic modules. This work is a great asset to the field of charge transport through organic pi-conjugated molecules.

The Texas City Disaster, 1947
by Hugh W. StephensOn April 16, 1947, a small fire broke out among bags of ammonium nitrate fertilizer in the hold of the ship Grandcamp as it lay docked at Texas City, Texas. Despite immediate attempts to extinguish the fire, it rapidly intensified until the Grandcamp exploded in a blast that caused massive loss of life and property. In the ensuing chaos, no one gave much thought to the ship in the next slip, the High Flyer. It exploded sixteen hours later. The story of the Texas City explosions-America's worst industrial disaster in terms of casualties-has never been fully told until now. In this book, Hugh W. Stephens draws on official reports, newspaper and magazine articles, personal letters, and interviews with several dozen survivors to provide the first full account of the disaster at Texas City. Stephens describes the two explosions and the heroic efforts of Southeast Texans to rescue survivors and cope with extensive property damage. At the same time, he explores why the disaster occurred, showing how a chain of indifference and negligence made a serious industrial accident almost inevitable, while a lack of emergency planning allowed it to escalate into a major catastrophe. This gripping, cautionary tale holds important lessons for a wide reading public.

Texas Shipwrecks (Images of America)
by Mark LardasThe Texas coastline and offshore waters are flat, shallow, featureless, and filled with shoals. Texas waters are subjected to extreme weather, not just hurricanes and tropical storms but also northers and seasonal gales. This, combined with two centuries of naval warfare off Texas waters, produced many shipwrecks of all sorts, from Spanish treasure fleets to simple working boats. The ships of pirates, navies, cotton traders, immigrants, fishermen, and oil shippers line the Texas coast, cover the sea bottom off Texas, and blanket the bottom of Texas rivers. Each wreck has a story, romantic or repellent, prosaic or unusual, but all intriguing.
Texas Takes Wing: A Century of Flight in the Lone Star State (Bridwell Texas History Series)
by Barbara GansonA history of aviation in Texas that &“brilliantly demonstrates the evolution of flight technology as a harbinger of social change&” (Technology and Culture). In this book, pilot and historian Barbara Ganson brings to life the colorful personalities that shaped the phenomenally successful development of the aviation industry in the Lone Star state. Weaving stories and profiles of aviators, designers, manufacturers, and those in related services, Texas Takes Wing covers the major trends that propelled Texas to the forefront of the field. Covering institutions from San Antonio&’s Randolph Air Force Base (the West Point of this branch of service) to Brownsville&’s airport with its Pan American Airlines instrument flight school (which served as an international gateway to Latin America as early as the 1920s) to Houston&’s Johnson Space Center, home of Mission Control for the US space program, the book provides an exhilarating timeline and engaging history of dozens of unsung pioneers as well as their more widely celebrated peers. Drawn from personal interviews as well as major archives and the collections of several commercial airlines, including American, Southwest, Braniff, Pan American Airways, and Continental, this sweeping history captures the story of powered flight in Texas since 1910. With its generally favorable flying weather, flat terrain, and wide-open spaces, Texas has more airports than any other state and is often considered one of America&’s most aviation-friendly places. Texas Takes Wing also explores the men and women who made the region pivotal in military training, aircraft manufacturing during wartime, general aviation, and air servicing of the agricultural industry. The result is a soaring history that will delight aviators and passengers alike. Includes photos
