实现了GPRS模块的信息发送，对开发GPRS模块很有帮助。

对于用户来说一款简单，方便，快捷的邮件收发系统将会在很大程度上为用户提供满意的服务，制作一款能满足用户需求的邮件收发系统是每一个设计者所追求的目标。该系统完成一个简单的邮件收发系统，实现邮件的接收与发送，并能完成附件的传输，同时能实现邮件用户登录管理及邮件删除等功能

云台解码器派尔高P协议，为原版协议，开发人员请注意其最后位校验，为异或校验，不是求和校验，这里很容易发生错误，我们在开发产品的时候搞错，头很大-PTZ decoder Pelco P protocol for the original agreement, the developer to draw your attention to the last bit checksum for the XOR checksum, not sum check, here are prone to error, we made a mistake when developing products , the first great

随着市场竞争的日益激烈，各个企业都想尽办法完善对客户的服务，电话客户服务便是企业推出的一项举措，通过电话与客户联系业务，为客户解答问题，但是在客户过多的情况下，难免出现问题，为了避免这种情况的发生，需要对所有的客户电话都录音，通过录音可以更好的了解客户的需求，也可以避免员工在工作中出现差错。-With the increasingly fierce market competition, all companies have tried every means to improve customer service, telephone customer service is the company launched an initiative on the phone with customer contact business, to answer questions for customers, but the customer too much circumstances, the inevitable problems, in order to avoid this from happening, the need for all customers calls are recorded through the recording could be a better understanding of customer needs, but also employees in their work to avoid errors.

对原始的 ALOHA 协议的改进是"时隙 ALOHA"，介绍了离散的时隙，并增加最大的吞吐量。一个站可以发送只有初时隙和因而减少碰撞事故。在这种情况下，我们只需要对传输尝试 1 帧时间内不连续 2 帧-次，担心，因为在每个时隙期间只能发生碰撞。

QAM源代码，方便大家使用，谢谢分享，其实我也有点无奈-QAM source code, easy to use you, thank you sharing, in fact, I feel quite helpless

使用VB的OPC客户访问的最简单程序,本程序为查找服务器、组、项目的列表程序，同步访问程序请找ASync-VB.rar,需要异步的查找ASync-VB.rar-The use of VB

CRC的验证，具体方法可以运用在许多程序中-CRC verification, specific methods can be used in many programs

在VB下面做的一个调用WINIO实现并口通讯的小例子（内含时序配合)-done in VB below the realization of a parallel port call WINIO communications small examples (intron timing tie)

ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels. Lenient thresholds give high sensitivity but low specificity, strict thresholds give high specificity but low sensitivity the ROC curve plots this trade-off over a range of thresholds (usually with sens vs 1-spec, but I prefer sens vs spec this code gives you the option). It is theoretically possible to operate anywhere on the convex hull of an ROC curve, so this is plotted too. The area under the curve (AUC) for a ROC plot is a measure of overall accuracy, and the area under the ROCCH is a kind of upper bound on what might be achievable with a weighted combination of differently thresholded results from the given classifier -ROC curves illustrate performance on a binary classification problem where classification is based on simply thresholding a set of scores at varying levels. Lenient thresholds give high sensitivity but

串口是串行接口（serial port）的简称，也称为串行通信接口或COM接口。 串口通信是指采用串行通信协议（serial communication）在一条信号线上将数据一个比特一个比特地逐位进行传输的通信模式。
