说明：  用matlab对一段音频信号进行采样，并用PCM编码后通过2FSK调制模拟信道传输，最后经过2FSK解调和PCM解码恢复音频信号(Matlab is used to sample a section of audio signal, PCM is used to code it, then it is transmitted through 2FSK modulation analog channel, and finally it is demodulated by 2FSK and decoded by PCM to recover the audio signal)

摄像机标定程序：用matlab语言编写，主程序为 Tsai，参考 TestData 以了解调用方法-camera calibration procedures : using Matlab language, the main program for Tsai, TestData reference to understand call methods

Handles Hexahedral, Tetrahedral, Quadrilateral, and Triangle meshes. Lagrangian, Hierarchic, and Monomial finite elements. Interface to PETSc solvers, adaptive mesh refinement, and extreme portablility.

说明：  这是一个基于pocketsphinx的例子程序，已经在andtoid studio编译成功，并能识别简单的词汇。这是第五部分(This is an example program based on pocketsphinx, which has been successfully compiled in andtoid studio and can recognize simple words. This is the fifth part.)

使用matlab编写并联机器人控制的源程序-The preparation of parallel robot using matlab source control

这是物联网相关的技术知识，其中包括各个实验的详细介绍(Technical knowledge related to the Internet of things)

微人事是一个前后端分离的人力资源管理系统，项目采用SpringBoot+Vue开发(Micro Personnel is a front-end and back-end separated human resources management system. The project is developed by SpringBoot+Vue.)

说明：  MQTT协议 3.1.1中文版 MQTT是一个客户端服务端架构的发布/订阅模式的消息传输协议。它的设计思想是轻巧、开放、简单、规范，因此易于实现。这些特点使得它对很多场景来说都是很好的选择，包括受限的环境如机器与机器的通信（M2M）以及物联网环境（IoT），这些场景要求很小的代码封装或者网络带宽非常昂贵。(MQTT is a messaging protocol in publish/subscribe mode of client server architecture. Its design idea is lightweight, open, simple and standardized, so it is easy to implement. These features make it a good choice for many scenarios, including limited environments such as machine-to-machine communication (M2M) and Internet of Things (IoT), which require very small code encapsulation or very expensive network bandwidth)

框出视频中的前景目标，可以用作圈出静止背景的小车(Box out of the video in the foreground, can be used as a circle around the background of the car)
