JDK 是整個(gè)Java的核心，包括了Java運(yùn)行環(huán)境（Java Runtime Envirnment），一堆Java工具和Java基礎(chǔ)的類(lèi)庫(kù)(rt.jar)。不論什么Java應(yīng)用服務(wù)器實(shí)質(zhì)都是內(nèi)置了某個(gè)版本的JDK。因此掌握 JDK是學(xué)好Java的第一步。最主流的JDK是Sun公司發(fā)布的JDK，除了Sun之外，還有很多公司和組織都開(kāi)發(fā)了自己的JDK，例如IBM公司開(kāi)發(fā)的JDK，BEA公司的Jrocket，還有GNU組織開(kāi)發(fā)的JDK等等。其中IBM的JDK包含的JVM（Java Virtual Machine）運(yùn)行效率要比Sun JDK包含的JVM高出許多。而專(zhuān)門(mén)運(yùn)行在x86平臺(tái)的Jrocket在服務(wù)端運(yùn)行效率也要比Sun JDK好很多。但不管怎么說(shuō)，我們還是需要先把Sun JDK掌握好。

Software-defined radios (SDRs) have been around for more than a decade. The first complete Global Positioning System (GPS) implementation was described by Dennis Akos in 1997. Since then several research groups have presented their contributions.We therefore find it timely to publish an up-to-date text on the subject and at the same time include Galileo, the forthcoming European satellitebased navigation system. Both GPS and Galileo belong to the category of Global Navigation Satellite Systems (GNSS).

This book has been written to support a practically oriented course in programming language translation for senior undergraduates in Computer Science. More specifically, it is aimed at students who are probably quite competent in the art of imperative programming (for example, in C++, Pascal, or Modula-2), but whose mathematics may be a little weak students who require only a solid introduction to the subject, so as to provide them with insight into areas of language design and implementation, rather than a deluge of theory which they will probably never use again students who will enjoy fairly extensive case studies of translators for the sorts of languages with which they are most familiar students who need to be made aware of compiler writing tools, and to come to appreciate and know how to use them. It will hopefully also appeal to a certain class of hobbyist who wishes to know more about how translators work.

This library implements the KLT Tracking algorithm [2004] for Feature Tracking in Video useful in computer vision tasks like object recognition, image indexing, tracking and structure from motion. This implementation uses programmable Graphics Hardware to achieve considerable speedup in the running time of the GPU-based implementation.

In communication systems channel poses an important role. channels can convolve many different kind of distortions to our information. In perticular wireless channels multipath distortion is sevear. and more sevear is such distortion is random. To handle this, multipath affected channels require Equalizers at receaver end. such equalizer uses different learning Algorithms for identifying channels continuously. This project is VHDL implementation of LMS learning algorithm with pipelined architecture. so this implementation can work with higher data rates with less clock speed requirments and so with less power consumpiton It uses Fixed point arithmatic blocks for filtering so suitable for coustom asic.

This control is another extension to the now standard and widely used ListView control. I have included some of the more common features: shaded columns, column sorting (with data type), but the real addition is the FILTERBAR features of the header. This implementation eliminates all of the work of dealing with the filter messages and item filtering by incorporating it into the control. This could have been implemented as delegates, but we create controls to do the work for us, don t we? I would like to thank Carlos H. Perez since a lot of the implementation came from examples he set with his ListViewEx control.

ImpulseC Codeveloper fft code. This file implements the hardware portion of a 256 sample FFT using a radix-4 algorithm. This implementation demonstrates that results similar to hand-coded HDL can be achieved using the C language, and without using a low-level style of C code.
