Description: Microsoft?Windows?HTTP Services (WinHTTP) provides developers with a server-supported, high-level interface to the HTTP/1.1 Internet protocol. WinHTTP is designed to be used primarily in server-based scenarios by server applications that communicate with HTTP servers. WinHTTP is also designed for use in system services and HTTP-based client applications. WinHTTP is more secure and robust than WinInet. However, SIngle-user applications that need FTP or gopher functionality, cookie persistence, caching, automatic credential dialog handling, Internet Explorer compatibility, or downlevel platform support should still consider using WinInet.

单片微型计算机是微型计算机发展中的一个重要分支，是把构成一台微型计算机的主要部件如中央处理器(CPU)、存储器(RAM/ROM)和各种功能I/O接口集成在一块芯片上的单芯片微型计算机(SIngle Chip Micro Computer),简称单片机.由于它的结构与指令功能都是按工业控制要求设计的,且近年来单片机着力扩展了各种控制功能如A/D、PWM等,因此我们更多时候称其为一个单片形态的微控制器(SIngle Chip Micro Controller),或直接称其为微控制器(Micro Controller)。

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.

MCPU is a minimal cpu aimed to fit into a 32 Macrocell CPLD - one of the smallest available programmable logic devices. While this CPU is not powerful enough for real world applications it has proven itself as a valuable educational tool. The source code is just a SIngle page and easily understood. Both VHDL and Verilog versions are supplied. The package comes with assembler, emulator and extensive documentation.

-The existence of numerous imaging modalities makes it possible to present different data present in different modalities together thus forming multimodal images. Component images forming multimodal images should be aligned, or registered so that all the data, coming from the different modalities, are displayed in proper locations. Mutual Information is the similarity measure used in this case for optimizing the two images. This method requires estimating joint histogram of the two images. The fusion of images is the process of combining two or more images into a SIngle image retaining important features from each. The Discrete Wavelet Transform (DWT) has become an attractive tool for fusing multimodal images. In this work it has been used to segment the features of the input images to produce a region map. Features of each region are calculated and a region based approach is used to fuse the images in the wavelet domain.
