Java technology is both a programming language and a platform. The Java programming language originated as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C++ was the language of choice. But over time the difficulties encountered with C++ grew to the point where the problems could best be addressed by creating an entirely new language platform. Design and architecture decisions drew from a variety of languages such as Eiffel, SmallTalk, Objective C, and Cedar/Mesa. The result is a language platform that has proven ideal for developing secure, distributed, network-based end-user applications in environments ranging from network-embedded devices to the World-Wide Web and the desktop

In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.

This document contains a detailed description of the usage and configuration of the JSVM [Joint Scalable Video Model] software for the Scalable Video Coding [SVC] project of the Joint Video Team [JVT] of the ISO/IEC Moving Pictures Experts Group [MPEG] and the ITU-T Video Coding Experts Group [VCEG]. It provides information how to build the software on Windows32 and Linux platforms. It contains a description of the usage and configuration for the binaries built from the software package, including examples for spatial, SNR and combined scalability scenarios. Guidelines for the integration and validation of new tools in the software are provided.

We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking fields, so that the anisotropy ratio tends to infinity, the D and B fields blow up near the cloaking surface. Since the metamaterials used to implement cloaking are based on effective medium theory, the resulting large variation in D and B will pose a challenge to the suitability of the field averaged characterization of " and 碌. We also consider cloaking with and without the SHS (softand- hard surface) lining, shown in [6] to be theoretically necessary for cloaking in the cylindrical geometry. We demonstrate numerically that cloaking is significantly improved by the SHS lining, with both the far field of the scattered wave significantly reduced and the blow up of D and B prevented.

The software is written in assembler, as it is very short and it need the speed in the main loop. This is the heart of the synth. To be precise, it s in the 7 lines of assembler that makes up the main loop. The rest of the code is the wavetables and the communication code.

This tutorial explains how to communicate with IO devices on the DE2 Board and how to deal with interrupts using C and the Altera Monitor Program. Two example programs are given that diplay the state of the toggle switches on the red LEDs. The fi rst program uses the programmed I/O approach and the second program uses interrupts.
