While teaching Java programming at Minnesota State University, the authors noticed that engineering students were enrolling in Java programming courses in order to obtain basic programming skills, but there were no Java books suitable for courses intended for engineers. They realized the need for a comprehensive Java programming tutorial that offers basic programming skills that can be applied in the field of engineering. With this in mind, the authors developed Java Programming for Engineers in order to meet the needs of both engineers and engineering students.

The text uses the personal computer as a development platform and assumes no prior programming experience or knowledge. The only skills expected of the reader are basic keyboarding and user-level familiarity with the PC. Topics covered range from mathematical expressions to linear systems to engineering graphics. Chapters on problem solving skills and the designing of engineering applications walk readers through real word problems they might encounter.

Divided into two parts, Part 1 is a description of the Java language, of the fundamentals of object orientation, input and output operations, and error handling. Part 2 is about Java programming for engineers. It starts with computer number systems, fixed- and variable-precision numeric data, mathematical programming in Java as could be of interest to engineers, and concludes with an overview of Java Graphics.

For the second or third programming course. A practical and unique approach to data structures that separates interface from implementation. This book provides a practical introduction to data structures with an emphasis on abstract thinking and problem solving, as well as the use of Java. It does this through what remains a unique approach that clearly separates each data structure's interface (how to use a data structure) from its implementation (how to actually program that structure). Parts I (Tour of Java), II (Algorithms and Building Blocks), and III (Applications) lay the groundwork by discussing basic concepts and tools and providing some practical examples, while Part IV (Implementations) focuses on implementation of data structures. This forces the reader to think about the functionality of the data structures before the hash table is implemented.

Driven by maturing Web service technologies and the wide acceptance of the service-oriented architecture paradigm, the software industry s traditional business models and strategies have begun to change: software vendors are turning into service providers. In addition, in the Web service market, a multitude of small and highly specialized providers offer modular services of almost any kind and economic value is created through the interplay of various distributed service providers that jointly contribute to form individualized and integrated solutions. This trend can be optimally catalyzed by universally accessible service orchestration platforms service value networks (SVNs) which are the underlying organizational form of the coordination mechanisms presented in this book.

Here, the authors focus on providing comprehensive business-oriented insights into today s trends and challenges that stem from the transition to a service-led economy. They investigate current and future Web service business models and provide a framework for Web service value networks. Pricing mechanism basics are introduced and applied to the specific area of SVNs. Strategies for platform providers are analyzed from the viewpoint of a single provider, and so are pricing mechanisms in service value networks which are optimal from a network perspective. The extended concept of pricing Web service derivatives is also illustrated. The presentation concludes with a vision of how Web service markets in the future could be structured and what further developments can be expected to happen.

This book will be of interest to researchers in business development and practitioners such as managers of SMEs in the service sector, as well as computer scientists familiar with Web technologies. The book s comprehensive content provides readers with a thorough understanding of the organizational, economic and technical implications of dealing with Web services as the nucleus of modern business models, which can be applied to Web services in general and Web service value networks specifically.."
