教务管理系统（c#）完整代码+数据库

这个里面有两本：一本PDF。不必仔细看，了解即可，它主要讲关于安装的细节。一本chm：《Ubuntu 实用学习教程》。这个要非常仔细地看，我就是从这个chm开始的。看完了这个chm教程后，建议大家再去下载这个教程，也是菜鸟级别的书，不过讲得要深入一些：从Windows转向Linux教程。我没具体看这本的教程，我直接借的图书馆的书，是随便找的——很老的一本书（好书都被其它同学给借走了），是清华大学出版的。我不是非常推荐这本书，我感觉即不太适合菜鸟看，也适合菜鸟看，因为里面对shell讲得比较细，当你有了一些linux操作经验后shell是必须得学的，此时你看此书才觉得深入浅出。因为此书

这是小弟学习java以来第一个完整的web项目，功能俱全，比如借书，还书，索引，管理员删除书，添加书本，学生预约，都已经实现，差的就是界面是黑白的，没有做前端，因为小弟的前端水平不怎么，水平有限，欢迎下载，希望各位多多下载支持，批评指正，小弟在此谢过了！！！

MOTIVATIONPropeller related acoustic signatures typically exhibit modulationcharacteristics. These modulation characteristics originate from the cavitationprocess that takes place in the water due to the cyclic movement of the propellerThe cavitation process is basically the collapse of air and vapor bubblesdue to variations in the static pressure. These variations in static pressure are aconsequence of the passage of the propeller blades through the water. Thismovement, cyclic in nature, causes amplitude modulation in the static pressureand as a consequence an amplitude-modulated(AM) signal can be detected in areceiverCyclostationary processing techniques have been used to detect andlentify analog and digital communication signals very successfully. Thesetechniques have the advantage of using a more realistic model for the signalthan the stationary model used in most of the more conventional signalprocessing techniquesB BACKGROUNDThe basic elements of cyclic spectral analysis are the time-variant cyclicperiodogram and the time-variant cyclic correlogram. These two functions form aFourier transform pair. This fact is known as the cyclic Wiener relation or thecyclic Wiener-Khinchin relation [Ref. 1: p. 49.1
