禾木正方教务管理系统成绩自动批量录入对接平台旨在解决在全国范围内使用范围甚广的"正方教务管理系统"成绩批量录入的问题,可以大大降低老师们的劳动强度,极大地提高工作效率。现在，大部分的学科成绩都是首先存放在excle表中，待进一步处理：添加平时分、试验分数等。尤其是一些学科使用了自动化的机考系统，考试完毕后，存储的成绩格式也最终可以存储为excel格式。当前，使用正方教务管理系统的学校很多。但是，老师们在录入成绩的时候很不方便，很容易输入错误，效率低下。本系统完美解决了上述问题，极高的提高了成绩录入效率：100人的成绩可以在2秒钟导入完毕，并且可以保证零错误率。大大降低了老师们的工作强度。本

对于K最短路问题，首先找出两点之间的所有路径，然后利用K最短路算法，将最短路、次短路、第三最短路等计算出来，存入数组中。该matlab程序具有很好的通用性，希望对大家有用。说明：findpath.m文件可计算出任意两点的所有路径，dijstra.m可算出两点间的最短路，main.m为K最短路算法，文件夹中附有一张计算结果图！

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
