【Objective and Requirement】
Objective： Be familiar with the creation of process and thread on Windows.
Requirement：
Sub Task 1: Create a console application, "child", which keeps printing out "The child is talking at [system time]" (in a loop, one per 1s).
Sub Task 2: Create another console application, "parent". It create a child process to execute “child”. The "parent" process keeps printing out "The parent is talking at [system time]". (one per 1s)
Execute "parent" and explain the output you see.
Sub Task 3: Create a "winPS" program which can output information about all the running processes. Try to output details about each process, such as PID, executable file name and path, etc.
Sub Task 4: In the "mainThread" program, use "CreateThread" to create a child thread. Both the main thread and the child thread keep printing out "[ThreadID] + [System time]".
session2
Objective： Create "ps" and "kill" commands on Windows.
Requirement：
Sub Task 1: On Linux/Unix there are a "ps" command and a "kill" command. The "ps" command can list information about all the running processes. The "kill" command can terminate processes. Based on the tasks finished in Session 1, create "ps" and "kill" commands on Windows. Tips: using "TerminateProcess" to "kill" a process.
session3
Objective： Learn how to use semaphore to solve IPC problems.
Requirement：
Task 3.1. Sleeping barber
Use semaphores to solve the problem of sleeping barber.
Task 3.2. Reader & Writer
Use semaphores to solve the reader and writer problem, with the readers (and writers) have higher priority.

Title: Upgrade Linux/Unix commands
Problem：
Write a program "supershell" that takes another command as an argument and executes that command. For instance, executing: “./supershell cat /usr/greg/readme" would invoke the cat command on the file /usr/greg/readme. After execution of the specified command has completed, "supershell" should display statistics that show some of the system resources the co

语音识别通过CNN
孤立词语音识别，复旦大学计算机科学技术学院数字信号处理期末项目
介绍
此仓库实现了一个强大的语音识别系统，该系统可以识别20个单独的单词，例如“语音”，“北京”，“文件”等。它利用从原始语音中提取的梅尔频谱特征，将频谱视为图片，卷积神经网络被用来对它们进行分类。
详细中文介绍请参考课程报告。
怎么玩
您需要一个支持CUDA（因为推理过程需要GPU）和flask的pytorch（版本> = 0.4）的python环境。 强烈建议使用Anaconda设置了环境，了解更多详情，请参考[]和[ ]（适用于中国大陆用户的方便，请参见[]）。
设置环境后，您可以通过键入以下内容轻松启动识别服务
python audio_server.py
进入您的命令行。 该命令将在端口22339上启动Web服务，因此您可以通过localhost:22339访问它
通过单击按钮，您的声音将被
