基于GMM的说话人识别
语音识别是近年来发展非常迅速的一项计算机智能技术，广泛应用在语音控制、身份识别等多个领域。本次项目主要研究语音识别的预处理过程和特征参数的提取环节。通过对原始语音信号进行预加重和分帧、加窗，滤除低频干扰，提升对语音识别有用的部分，消除了部分噪音和失真。预处理之后进行信号的特征提取，主要选取了短时平均过零率和MFCC两个特征参数，应用matlab软件绘制波形图并提取特征参数矩阵，为之后的语音信号的识别打下了基础。(Speech recognition is a computer intelligent technology which has developed rapidly in recent years. It is widely used in speech control, identity recognition and other fields. This project mainly studies the pretreatment of speech recognition and the extraction of feature parameters. Through pre-emphasis, framing and windowing of the original speech signal, the low frequency interference is filtered out, the useful part of speech recognition is enhanced, and some noise and distortion are eliminated. After pretreatment, feature extraction of signal is carried out. Two feature parameters, short-term average zero-crossing rate and MFCC, are selected. Waveform diagram is drawn by MATLAB software and feature parameter matrix is extracted, which lays a foundation for speech signal recognition.)

Dynamicallyforecastingnetworkperformanceusingthene
网络服务正在更新换代并且可扩展设备被设计成可提供在元计算环境中动态资源行为预测。这篇文章里，我们描述了预测产生的的设计和预测行为的细节。当预测方式为普通方式时，我们关注与他对TCP/IP端到端吞吐量能力的预测和在不同地点使用不同系统会带来的延迟量。因为在元计算软件的基础上网络预测需要计划的支持和质量服务保证的提高。(The Network Weather Service is a generalizable and extensible facility designed to provide dynamic resource performance forecasts
in metacomputing environments.In this paper,we outline its design and detail the predictive performance of the forecasts it generates.
While the forecasting methods are general,we focus on their ability to predict the TCP/IP end-to-end throughput and latency that is
attainable by an application using systems located at differentsites.Such network forecasts are needed both to support scheduling
(Bermanetal.,1996)and,by the metacomputing software infrastructure,to develop quality-of-service guarantees(DeFantietal.,to
appear Grimshawetal.,1994).

costas_ClosedLoop
A Costas loop is a phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. It was invented by John P. Costas at General Electric in the 1950s. Its invention was described as having had "a profound effect on modern digital communications".
