Description: 《基于asp.net在线考试平台开发与设计》本系统的设计是为了方便各学校的出卷而进行的。它不仅有利于老师对试题的管理、试题自由录入，而且还能够帮助老师们解决出卷的问题。由于这是网络版的项目,因此它更好的实现了信息资源的共享。
本系统从总体上可以分为两大块：试题管理、在线考试，具体由试题的管理、录入试题、编辑试题几个部分构成。
该系统是基于ASP.NET(动态服务网页)技术+SQL SERVER 2000为基础而开发的课题，开发过程中运用了页面模块化、构件化及信息发布的动态生成、静态页面显示等技术。
关键词：试题管理，在线测试。
-System this design for help to produce roll and go on at all levels school. It not merely helps teacher s control over examination question , examination question to input freely, and can also help the teachers to solve the problem that appearsed . Because this is a project of a network edition, so the realizations of information resources haring is better.
This system can be divided into two module on the whole: The management of the examination question , publishing one automatically is concrete by the management , inputting several parts of examination question , editor s examination question .
This system is on the basis of technological+SQL SERVER 2000 subject developed for foundation of ASP.NET (dynamic service webpage ), have developed and used page module , producing dynamically , technology that the static page shows ,etc. of the component and information issue in the course.

Description: Euler方法 用C语言实现，并求解常微分方程组-The m framework appropriately generalizes notions such as gain margin, phase
margin, disturbance attenuation, tracking, and noise rejection into a common
framework suitable for analysis and design, in both single-loop and multiloop
feedback systems. Even when working with single-loop feedback systems, some
multi-input, multi-output (MIMO) systems arise during the analysis. Hence, a
unified framework to deal with MIMO linear systems is important, with full
support for both the time and frequency domain. m-Tools provides the
capability to build complex interconnections (such as cascade, parallel, and
feedback connections), compute properties (such as poles and zeros), calculate
time and frequency responses, manipulate these responses (FFT for the time
domain signals, Bode analysis for the frequency domain functions), and plot
results. m-Tools supports two data types in addition to the standard matrices:

Description: In most cases, a bandpass filter characteristic
is obtained by using a lowpass-to-bandpass frequency
transformation on a known lowpass transfer function. This
frequency transformation controls the location of passband
edges and transfer zero frequencies completely. Using the
“Vlach-Chebyshev approximation” [1] however, we are
able to specify the (Chebyshev) passband limits directly,
together with a free choice of transfer zero locations in the
stopband. In this way it is possible to design bandpass
transfer functions that cannot be obtained from lowpass
functions by a frequency transformation. We think this
method to be the only (and not very well known) analytical
method to obtain such bandpass characteristics. We show
how we designed wave digital realizations from the specification,
through a VHDL description and synthesis into a
Xilinx FPGA (Virtex-II).

Description: This examples corresponds to a 2x2 system with parallel linear arrays, where the mobile moves aways from the base station,
with a constant speed such that the Maximum Doppler frequency is 5 Hz. The element spacings at the base station and mobile are one lambda and 0.5 lambda, respectively. The maximum angle spread at the base station is 4 degrees, whereas isotropic scattering is assumed around the mobile. The length of the simulated MIMO channel is 5 seconds, and any two adjacent samples are spaced by 0.01 seconds. For ensemble averaging, 90 realizations of the MIMO channel are generated.-This examples corresponds to a 2x2 system with parallel linear arrays, where the mobile moves aways from the base station, with a constant speed such that the Maximum Doppler frequency is 5 Hz.

Description: Satellite
Communication
Engineering
The aim of this book is to present in a simple and concise manner the
fundamental principles common to the majority of information communications
systems. Mastering the basic principles permits moving on to concrete
realizations without great difficulty. Throughout, concepts are developed
mostly on an intuitive, physical basis, with further insight provided by means of a combination of applications and performance curves. Problem sets
are provided for those seeking additional training. Starred sections containing
basic mathematical development may be skipped with no loss of continuity by
those seeking only a qualitative understanding. The book is intended for
electrical, electronics, and communication engineering students, as well as
practicing engineers wishing to familiarize themselves with the broad field of
information transmission, particularly satellite communications.
