Taschenbuch. Condizione: Neu. Neuware - Software testing is indispensable and is one of the most discussed topics in software development today. Many companies address this issue by assigning a dedicated software testing phase towards the end of their development cycle. However, quality cannot be tested into a buggy application. Early and continuous unit testing has been shown to be crucial for high quality software and low defect rates. Yet current books on testing ignore the developer's point of view and give little guidance on how to bring the overwhelming amount of testing theory into practice. Unit Testing in Java represents a practical introduction to unit testing for software developers. It introduces the basic test-first approach and then discusses a large number of special issues and problem cases. The book instructs developers through each step and motivates them to explore further. \*Shows how the discovery and avoidance of software errors is a demanding and creative activity in its own right and can build confidence early in a project. \*Demonstrates how automated tests can detect the unwanted effects of small changes in code within the entire system.\*Discusses how testing works with persistency, concurrency, distribution, and web applications.\*Includes a discussion of testing with C++ and Smalltalk.

Buch. Condizione: Neu. Neuware - As a result of the increased focus on modern compact machinery in industry, wear in lubricated contacts and the problems of running in, and scuffing has become the most important form of wear.Despite this trend, until now information on lubricated wear has been scattered across a wide number of journals, emphasizing only one aspect of the wear process. This new book is a unique resource, consolidating all the available information into one place. In doing this Sethuramiah, contributes significantly to the development of knowledge in the field, by highlighting knowledge gaps for future research. More immediate improvements in practice have been clearly identified with well-argued methodologies with which the present level of knowledge can be improved. This book will therefore prove an essential resource for all engineers and scientists with an interest in lubricated wear.

Buch. Condizione: Neu. Neuware - Arc welding is one of the key processes in industrial manufacturing, with welders using two types of processes - Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW). This book provides a survey-oriented account of the modeling, sensing, and automatic control of the GMAW process.

Buch. Condizione: Neu. Neuware - The book provides a comprehensive state-of-the-art overview of current research on cognitive and applied aspects of eye movements. The contents include peer-reviewed chapters based on a selection of papers presented at the 11th European Conference on Eye Movements (Turku, Finland 2001), supplemented by invited contributions. The ECEM conference series brings together researchers from various disciplines with an interest to use eye-tracking to study perceptual and higher order cognitive functions. The contents of the book faithfully reflect the scope and diversity of interest in eye-tracking as a fruitful tool both in basic and applied research. It consists of five sections: visual information processing and saccadic eye movements; empirical studies of reading and language production; computational models of eye movements in reading; eye-tracking as a tool to study human-computer interaction; and eye movement applications in media and communication research. Each section is concluded by a commentary chapter by one of the leading authorities in the field. These commentaries discuss and integrate the contributions in the section and provide an expert view on the most significant present and future developments in the respective areas. The book is a reference volume including a large body of new empirical work but also principal theoretical viewpoints of leading research groups in the field.
