Enterprise Java Beans enable rapid and simplified development of secure and portable applications based on Java technology. Creating and using EJBs can be challenging and rewarding. Among the challenges are learning the EJB technology itself, learning how to use the development environment you have chosen for EJB development, and the testing...

Ad hoc and sensor networks continue to have a growing impact on communication. These cost-effective wireless networks provide location independent computing in environments ranging from military battlefields to in-home patient monitoring systems. However, having real-time connectivity to critical information over an open...

Wiley-Interscience Series in Discrete Mathematics and Optimization Advisory Editors Ronald L. Graham Jan Karel Lenstra Robert E. Tarjan Discrete Mathematics and Optimization involves the study of finite structures. It is one of the fastest growing areas in mathematics today. The level and depth of recent advances in the area and the wide...

This book is intended as an introduction to the design of digital processors that are dedicated to performing a particular task. It presents a number of general methods and also covers general purpose architectures such as programmable processors and configurable logic. In fact, the dedicated digital system might be based on a standard...

During the 1980's the flat relational model (relational model), which was initiated by Codd in 1970, gained immense popularity and acceptance in the market place. One of the main reasons for this success is that the relational model provides physical data independences i.e. changing the physical organization of the database does not...

Network monitoring serves as basis for a wide scope of network operations, engineering and management. Precise network monitoring involves inspecting every packet traversing in a network. However, this is infeasible in today’s and future high-speed networks, due to significant overheads of processing, storing, and transferring...

Advanced Database Query Systems: Techniques, Applications and...

Computer users spend a lot of time doing simple, mechanical data manipulation - changing the format of data, checking its validity, finding items with some property, adding up numbers, printing reports, and the like. All of these jobs ought to be mechanized, but it's a real nuisance to have to write a specialpurpose program in a...

The idea of describing how to make multimodal computer systems usable arose in the European Network of Excellence SIMILAR – “Taskforce for creating human-machine...

The modern world offers lots of readily available online resources for learning. Wikipedia, Google, news sources, millions of Web sites and blogs, even YouTube, offer access to information in nearly any subject that triggers your curiosity and interest. Nonetheless, I continue to believe that for deep understanding of something, nothing...
