Software test automation h Product Description Software test automation has moved beyond a luxury to become a necessity. Applications and systems have grown ever larger and more complex, and manual testing simply cannot keep up. As technology changes, and more organizations move into agile development, testing must adapt-and quickly. Test automation is essential, but poor automation is wasteful-how do you know where your efforts will take you? Authors Dorothy Graham and Mark Fewster wrote the field´s seminal text, Software Test Automation, which has guided many organizations toward success. Now, in Experiences of Test Automation, they reveal test automation at work in a wide spectrum of organizations and projects, from complex government systems to medical devices, SAP business process development to Android mobile apps and cloud migrations. This book addresses both management and technical issues, describing failures and successes, brilliant ideas and disastrous decisions and, above all, offers specific lessons you can use. Coverage includes Test automation in agile development How management support can make or break successful automation The importance of a good testware architecture and abstraction levels Measuring benefits and Return on Investment (ROI) Management issues, including skills, planning, scope, and expectations Model-Based Testing (MBT), monkey testing, and exploratory test automation The importance of standards, communication, documentation, and flexibility in enterprise-wide automation Automating support activities Which tests to automate, and what not to automate Hidden costs of automation: maintenance and failure analysis The right objectives for test automation: why ´´finding bugs´´ may not be a good objective Highlights, consisting of lessons learned, good points, and helpful tips Experiences of Test Automation will be invaluable to everyone considering, implementing, using, or managing test automation. Testers, analysts, developers, automators and automation architects, test managers, project managers, QA professionals, and technical directors will all benefit from reading this book.

This book addresses and introduces new developments in the field of Quantum Information and Computing (QIC) for a primary audience of undergraduate students. Developments over the past few decades have spurred the need for QIC courseware at major research institutions. This book broadens the exposure of QIC science to the undergraduate market. The subject matter is introduced in such a way so that it is accessible to students with only a first-year calculus background. Greater accessibility allows a broader range of academic offerings. Courses, based on this book, could be offered in the Physics, Engineering, Math and Computer Science departments. This textbook incorporates Mathematica-based examples into the book. In this way students are allowed a hands-on experience in which difficult abstract concepts are actualized by simulations. The students can ´turn knobs´´ in parameter space and explore how the system under study responds. The incorporation of symbolic manipulation software into course-ware allows a more holistic approach to the teaching of difficult concepts. Mathematica software is used here because it is easy to use and allows a fast learning curve for students who have limited experience with scientific programming.
´´This is a crucial and timely book on ethics in engineering and science by one of the world´s foremost ethicists of technology and society. Every engineering department should read and use this book for planning their curricula.´´--Stephen R. Barley, University of California, Santa Barbara´´The Ethical Engineer offers a highly original and rich conceptual portrait of the many ethical facets of engineering practice today. Through a sophisticated analysis of issues encountered in a vast array of context-specific domains and engineering fields, this book offers powerful and much-needed tools to equip engineers with an ethical mindset that informs their understanding and guides them in their day-to-day professional conduct.´´--Rafael Pardo, director of the BBVA Foundation´´Engineering and science are among the strongest of social forces, but with their long latency, the good and bad resulting from these fields can be difficult to foresee. Nuclear weapons, combustion engines, chemistry-based agriculture, the internet, and machine intelligence--all are examples of areas posing ethical challenges for society and the educational institutions tasked with the development of citizenship. Timely and welcome, The Ethical Engineer articulates thoughtful, robust approaches to such complex issues.´´--Sandip Tiwari, Cornell University´´McGinn has written a highly accessible and very useful guide for courses on engineering ethics. Students will acquire a sense of the issues they should be concerned with as well as a feel for the challenges they will face as engineers. There is no other book quite like this one, and it will be a boon to engineering education everywhere.´´--Daniel Doneson, Massachusetts Institute of Technology´´This tremendously valuable book does a good job of distilling contemporary issues in engineering ethics and of making the case that ethics must be included in an engineer´s education. The book effectively incorporates theory, examples, and resources and demonstrates that engineering ethics is continuously evolving.´´--Raluca Scarlat, University of Wisconsin?Madison´´In the past, I have struggled to find a book that contains engineering ethics cases with adequate ethical review and analysis. The Ethical Engineer has them and I would recommend it for classroom use.´´--Dianne Quigley, Brown University
Spectral methods, particularly in their multidomain version, have become firmly established as a mainstream tool for scientific and engineering computation. While retaining the tight integration between the theoretical and practical aspects of spectral methods that was the hallmark of their 1988 book, Canuto et al. now incorporate the many improvements in the algorithms and the theory of spectral methods that have been made since then. This second new treatment, Evolution to Complex Geometries and Applications to Fluid Dynamics, provides an extensive overview of the essential algorithmic and theoretical aspects of spectral methods for complex geometries, in addition to detailed discussions of spectral algorithms for fluid dynamics in simple and complex geometries. Modern strategies for constructing spectral approximations in complex domains, such as spectral elements, mortar elements, and discontinuous Galerkin methods, as well as patching collocation, are introduced, analyzed, and demonstrated by means of numerous numerical examples. Representative simulations from continuum mechanics are also shown. Efficient domain decomposition preconditioners (of both Schwarz and Schur type) that are amenable to parallel implementation are surveyed. The discussion of spectral algorithms for fluid dynamics in single domains focuses on proven algorithms for the boundary-layer equations, linear and nonlinear stability analyses, incompressible Navier-Stokes problems, and both inviscid and viscous compressible flows. An overview of the modern approach to computing incompressible flows in general geometries using high-order, spectral discretizations is also provided. The recent companion book Fundamentals in Single Domains discusses the fundamentals of the approximation of solutions to ordinary and partial differential equations on single domains by expansions in smooth, global basis functions. The essential concepts and formulas from this book are included in the current text for the reader s convenience.

When Joe O´Connor left a corrupt aerospace engineering firm to start his own business, he set up a two-way tap to protect himself and his interests. Little did he know that just a short time later, through this clandestine surveillance system, he would learn that there is an intergalactic shadow government, one whose tentacles have been operating longer than the earth itself. His system also puts him into contact with three likeminded women, and Joe´s straightforward, no-nonsense approach is a perfect match for the threesome. Soon enough their insight opens a whole new world of possibilities. Uncovering the tentacles of the intergalactic conspiracy, their relationships blossom and the new group of collaborators immediately begin working on an interdimensional level. As their efforts become more complex and Joe sees their inherent possibilities, he incorporates a strategy for his electronics firm that earns profits in harmony with the divine evolution of the planet. Oblivion´s Deal elaborates the Oblivion Series even further as volume four of the epic.

The Distressor is an automatic gain (or volume) control device (AGC in engineering terms) designed for pro audio (music) applications. Basically, it electronically controls the volume of just about any source in a very pleasing, and musical manner - adding fullness, intelligibility, and especially in the Distressor´s case - excitement. This type of device is often called a limiter or compressor by audio industry people. Its most probable uses will be in recording studios, live sound situations, movie sound production, and radio broadcast production. Unlike most analog compressor/limiters the Distressor is a digitally controlled audio device and actually incorporates several products into one by utilizing digital controls to switch totally different circuits in and out. Years of beta testing and redesign went into the Distressor as will be the case with all Empirical Labs products.Besides offering a wide range of control and unique features, the Distressor offers a warm, vintage sound by using a custom designed gain control circuit. This warmth or vintage sound has become an important issue in the last 15 years, as the super clear and linear digital technology does very little (or nothing) to soften harsh sounds nor emphasize the bass frequencies in music sources. Older analog tape, vinyl records and tube equipment on the other hand, could not be prevented from coloring the sound, often to the frustration of recording engineers. However, many people have now realized that this coloring can be extremely pleasant and musical.The current digital technology is often referred to as cold and brittle among other terms, although we prefer the term unforgiving to describe the negative side of the linearity. The Distressor offers several modes that color the signal, even without compression (or gain control). These extended modes were designed to allow emulation of some very old and some very expensive vintage gain control units (compressors & limiters) and deliver a classic knee sound all its own.Specifications * Freq. response is 2 Hz to 160 kHz in clean audio mode (+0, -3 dB). Response is shaped in distortion modes (Dist 2, Dist 3). * Dynamic range 110 dB from max. output to min. output in 1:1 mode. Greater than 100 dB signal to noise in distort 3 mode. * Distortion ranges between .02% and 20% depending on distortion mode and release times set on front panel. * DC coupled output - High quality input caps. * Input impedance is 20K Ohms, Output impedance is * Time constants - Attack range 50uS - 50mS. Release range .05 sec to 3.5 seconds, normal modes and up to 20 seconds in 10:1 opto mode. Time constants are dependant on ratio. * Metal Chassis - single height 1.75 high, 10 deep, 19 wide. * Shipping info - 12.1 lbs mono, 24.2 lbs Stereo pair. Mono box dimensions 22.5 x 18.5 x 3 1/4.
