Description: This document is intended to serve as an introduction to Wavelet processing through a set of Matlab experiments. These experiments will gives an overview of three fundamental tasks in signal and image processing : signal, denoising and compression. These scripts are selfs contents (needed additional Matlab functions can be downloaded while reading the lectures).
Each one of these five lectures should take between 1h and 2h in order to tests the various features of the scripts. One should copy/paste the provided code into a file names e.g. tp1.m, and launch the script directly from Matlab comand line > tp1 . Some of the scripts contains \"holes\" that you should try to fill on your own.
I also provide the complete correction of these lectures as a set of Matlab scripts, but you should try as much as possible to avoid using them.

Description: RNNSIM v.2 package contains a number of m-files for training and evaluation
of the random neural network. All functions have been thoroughly tested.
After downloading the separate files or the zipped file, make sure that they are
stored or extracted in the directory /rnnsimv2
Below an overview of the files contained in this directory along with a brief description of what
they do. The on-line help facility explains how to call the different functions. You simply write
help <function-name> in the MATLAB command window.
Along with the m-files in this directory you will find a manual for the simulator
in PDF format (rnnsimv2.pdf). Start by printing this out and read the release notes.
Two simple demonstration programs are given to illustrate how most of the functions
work. -RNNSIM v.2 package contains a number of m-files for training and evaluation

Description: 共振解调法诊断轴承损伤类故障的原理概述如下:当轴承某一元件表面出现局部损伤时，在受载运行过程中要撞击与之相互作用的其它元件表面，产生冲击脉冲力，由于冲击脉冲力的频带很宽，必然包含轴承外圈、传感器甚至附加的谐振器等的固有频率而激起这个测振系统的高频固有振动。根据实际情况可以选择某一高频固有振动作为研究对象，通过中心频率等于该固有频率的带通滤波器把该固有振动分离出来。然后进行包络解调，去除高频衰减振动的频率成分，得到只包含故障特征信息的低频包络信号，对这一包络信号进行频谱分析便可以容易地诊断出轴承的故障来。-The principle of resonance demodulation method in the diagnosis of bearing damage such failure overview is as follows: when the bearing surface of a local damage, in the process of loading operation to hit with other elements of the interaction of surface, impact pulse power, due to the impact pulse frequency band is very wide, inevitably contains the bearing outer ring, sensors and even additional resonator and stir up the natural frequency of the vibration system of the high frequency vibration mode.A high frequency vibration mode can be selected according to actual situation as the research object, through the center frequency is equal to the natural frequency of the bandpass filter to separate the natural vibration.Then envelope demodulation, frequency components to remove the high frequency vibration attenuation, get only includes fault feature information of low frequency envelope signal, the envelope signal spectrum analysis can be easily diagnosed bearing failure.

Description: MM1_Tutorial
Objective
This laboratory is important for understanding OPNET system and user interface. The lab contains a step-by-step example that shows how to use OPNET to construct an M/M/1 queue design and analysis. Overview
The task is to construct an M/M/1 queue model and observe the performance of the queuing system as the packet arrival rates, packet sizes, and service capacities change. Two classes of statistics will be measured, Queue Delay and Queue Size. A graph of the confidence interval will also be produced.
This laboratory also introduces the use of:
