Project Title: Analysis of Cardiovascular System using Back Propagation Algorithm.
Team Members: R.Senthilkumar, A.Venkatesan, R.Ramesh and R.Muthukaruppasamy.
Project Guides: Prof. S. Selvan & Mrs. N.Kaliammal
Abstract (Synopsis)
In day today life, it is difficult to classify the symptoms under various diseases. It is more difficult in the case of cardiovascular system because it has numerous amounts of diseases with complicated symptoms. So we are in need of a system which classifies the various symptoms under the corresponding disease. For the classification problem we can use Neural Networks which biologically inspired and they work in a manner analogous to the biological neuron. Is has several algorithms to work with. But the well suited algorithm for Pattern Recognition is BACK PROPAGATION algorithm.
The Back Propagation algorithm is of the type of supervised learning. Training is modification of weights (connective values between two neurons). In training, the training sets are given as input with their target vector and trained according to the algorithm until the error is minimized. The modified weights are saved and stored.
In the recognition the symptoms are given as input to neural network and the corresponding output is got. The o/p value is compared with a threshold and the disease is identified according to the threshold value. This neural system is implemented in computer by using Turbo version 2.0 of C++ and Visual Basic6.0. C++ is used for this purpose because it works in a object oriented approach and is very easily supports various file handling options. Hence we can easily approach the various functions as separate objects. Visual Basic is mainly used front end design and for programming as like C++.

PG Thesis
Project Title: Implementation of Acoustic Echo Canceller and Double Talk Detector.
Team Member: R.Senthilkumar
Project Guides: Mrs.S.Umamaheswari
Abstract (Synopsis)
Echoes produced in a closed room are one among the major problems in telephone communication. These Echoes are bigger in size when compared to the echoes due to improper hybrid transformer and line mismatching. Hence Acoustic Echo Canceller (AEC) plays a vital role in telephone communication.
In this project Acoustic Echo Canceller(AEC) and Double Talk Detector (DTD) are implemented by using different methods and these methods are compared. This project work also gives the solution for various problems that arise in the implementation of AEC and DTD.
Speech signals are recorded in different rooms and they are used as Far-End Speaker (FES) input and Near End Speaker (NES) input. First and AEC is developed with different possible structures without considering NES and Noise. For DTD implementation, speech signals recorded in a separate room is used as NES signal. Then a final system is developed which includes all possible criteria such as room impulse response, presence of double talk and noise.
From the results obtained, it is concluded that subband coding require reduced convergence time when compared to the full band coding. Polyphase DFT is superior than all other proposed systems and System using Polyphase Decimator and Interpolator is having worst execution period. In DTD methods Geigel algorithm is suitable for strong NES signal and Normalized cross correlation method is suitable for weak NES signal.
