RFID is an area of automatic identifi cation that is gaining momentum and is considered by some to emerge as one of the most pervasive computing Technologies in history. In its simplest form, RFID is a similar concept to bar coding. It is seen as a means of enhancing data processes and is comple- mentary to existing Technologies. It is a proven technology that has been in use since the 1970s.

This paper shows the development of a 1024-point radix-4 FFT VHDL core for applications in hardware signal processing, targeting low-cost FPGA Technologies. The developed core is targeted into a Xilinx廬 Spartan鈩?3 XC3S200 FPGA with the inclusion of a VGA display interface and an external 16-bit data acquisition system for performance evaluation purposes. Several tests were performed in order to verify FFT core functionality, besides the time performance analysis highlights the core advantages over commercially available DSPs and Pentium-based PCs. The core is compared with similar third party IP cores targeting resourceful FPGA Technologies. The novelty of this work is to provide a lowcost, resource efficient core for spectrum analysis applications.

Abstract. The main aim of this research is to improve communication between student and teacher by using the developing mobile information Technologies. Implementing such Technologies in education may help to develop learning environments to share the knowledge among students and increase their motivation to possible highest level. Based on mobile equipments used in daily life an online student announcement system has been developed which aims to provide sharing of documents and communication ways between students and teachers.

Watermarking schemes evaluation Abstract鈥擠igital watermarking has been presented as a solution to copy protection of multimedia objects and dozens of schemes and algorithms have been proposed. Two main problems seriously darken the future of this technology though. Firstly, the large number of attacks and weaknesses which appear as fast as new algorithms are proposed, emphasizes the limits of this technology and in particu-lar the fact that it may not match users expectations. Secondly, the requirements, tools and methodologies to assess the current Technologies are almost non-existent. The lack of benchmarking of current algorithms is bla-tant. This confuses rights holders as well as software and hardware manufacturers and prevents them from using the solution appropriate to their needs. Indeed basing long-lived protection schemes on badly tested watermarking technology does not make sense.

With this example-driven book, you get a quick, practical, and thorough introduction to Java s API for XML Web Services (JAX-WS) and the Java API for RESTful Web Services (JAX-RS). Java Web Services: Up and Running takes a clear, no-nonsense approach to these Technologies by providing you with a mix of architectural overview, complete working code examples, and short yet precise instructions for compiling, deploying, and executing a sample application. You ll not only learn how to write web services from scratch, but also how to integrate existing services into your Java applications. All the source code for the examples is available from the book s companion website.

The software and hardware development fields evolved along separate paths through the end of the 20th century. We seem to have come full circle, however. The previously rigid hardware on which our programs run is softening in many ways. Embedded systems are largely responsible for this softening. These hidden computing systems drive the electronic products around us, including consumer products like digital cameras and personal digital assistants, office automation equipment like copy machines and printers, medical devices like heart monitors and ventilators, and automotive electronics like cruise controls and antilock brakes. Embedded systems force designers to work under incredibly tight time-tomarket, power consumption, size, performance, flexibility, and cost constraints. Many Technologies introduced over the past two decades have sought to help satisfy these constraints. To understand these Technologies, it is important to first distinguish the underlying embedded systems elements.
