1.1 Parallel Computation of Image Matching Application Fall 2015

Objective:

Build a parallel computational network to execute an Image Matching application

in a relatively fast manner using C++, SSD (Sum of Square Differences) algorithm

and MPI (Message Passing Interface) library.

Software:

Linux Operating System with GNU Compiler Collection (GCC)

Overview:

In order to compile this project, a parallel network among 12 computers using RSA

cryptosystem was created and used to execute the Image Matching application.

The main objective of this project was to reduce the communication overhead and

latency to achieve the maximum possible outcome of parallel computation. It is

observed in the experiment that the performance gain is linear with the number of

processors used for the execution of the application.

2.1 DC Motor Analysis Winter 2015

Objective: Calculate the DC motor efficiency and its parameters (armature constant, motor

resistance and inductance) using the basic principles of Dynamometer.

Part List:

Mechanically coupled DC motor and generator, tachometer and multimeter

Overview: This project was about calculating a DC motor efficiency and its parameters by

coupling the motor with a DC generator and measuring shaft speed, generator and

motor voltages for no load and with load configurations. Motor efficiency was

calculated, along with armature constant, resistance and inductance using several

mathematical equations. Furthermore, the motor response was simulated in

Simulink software with a four quadrant chopper to achieve motor stability.

Accomplishments:

Proficiency with Simulink software was gained and knowledge about the basic principal of dynamometer and four quadrant chopper was acquired.

2.2 Data Acquisition System Winter 2013

Objective:

Build a data acquisition system to convert several real time physical values into

digital numeric values like force and angle to display them on a LCD display.

Part List:

9s12C32 Esduino Board, EADOG LCD, Memic2125 accelerometer, AD620AN

Instrumentational amplifier.

Overview:

This project was about programming 9s12C32 Esduino board using C

programming language to convert load cell weight and an accelerometer angle into

digital numeric values so it can be shown on a LCD display. Certain limits were

set on load cell weight and accelerometer angle to protect the system and display

them in the danger stage. An instrumentational amplifier was used to overcome the

debouncing issue with the switch. Furthermore, this project was performed under

precise time constraints and short deadlines.

Accomplishments:

Proficiency in C programming language, hardware soldering and solution to switch debouncing was gained.

2.3 Linear Voltage Controlled Waveform Generator Winter 2013

Objective:

Implement a user controlled waveform generator to produce square and triangular

waveforms through an external DC source.

Part list:

LM318 and LM741 amplifiers, Capacitors, Diodes and MOSFET transistors

Overview

This project was designed using a bi-stable vibrator and an integrator. When an

external DC source was applied to the integrator, it integrated the signal and

generated a triangular waveform. Similarly, when the integrated signal was

inserted into a bi-stable vibrator it generated the square waveform, since there was

no negative feedback loop.

Accomplishments:

Hands on experience with Multisim software was gained and hardware testing

skills were enhanced.
