Electrical Engineering

“Engineering, electrical and mechanical, is positive in results. There is scarcely a subject that cannot be mathematically treated and the effects calculated or the results determined beforehand from the available theoretical and practical data. The carrying out into practise of a crude idea as is being generally done is, I hold, nothing but a waste of energy, money and time.” - Nikola Tesla

Eye tracking software main screen
Pupil Tracking Communication Software for Non-Verbal Individuals

I built a software application that would allow stroke patients suffering from complete paralysis, other than eye movement, to move a cursor on the screen using their eyes. The program allowed them to click and communicate on the screen using a virtual keyboard and prompts. This was done using linear adaptive filtering techniques using the coding language C++ in conjunction with OpenCV libraries on Visual Studio.
AutoCAD drawing of chicane in Pelham
Site Service Plan for Chicane on Haist Street in Pelham

I drafted a site service pland for a chicane on Haist street in Pelham, Ontario. The purpose of the plan was to submit it to the city so that city council can determine whether it needed to be removed (due to multiple complaints). I used AutoCAD for the plan where I maintained scale and accuracy of the chicane as well as the surrounding areas.

PowerWorld Simulation for Solar Farm and Smart Grid Utilization

I designed a makeshift power grid utilizing the PowerWorld Simulator. This involved the sizing and design of the production, transmission and distribution (substation) of power to the customer. I had to size the solar panels needed for the production. In addition to this, I sized cables for three-phase transmission at 100kV, 500MVA. On top of that, I had to size transformers for stepping up and down voltage. Lastly, safety systems had to be put in place, such as lightning arresters, fuses, circuit breakers and relays to prevent faults in the larger grid.

Microsoft SQL Server Logo
Microsoft SQL Database Creation and Maintenance

For the steel company, Dofasco, in Hamilton, I had to update many of the legacy Microsoft Accesss databases to the current implementation of Microsoft SQL Server. Data integrity had to be maintained across the hundreds of databases for the Materials Handling and Logistics part of the company.

Schematic for additive manufacturing process
Laser Consolidation System

Designed the code for a metal power feeder and laser using Visual Basic on Visual Studio for the National Research Council. The system utilized a metal powder feeder, laser and motion setup for advanced 3d printing metal manufacturing. The program had to control paramters such as metal type, flow rate, laser intensity, etc. The system utilized g-code to move a cnc machine to draw out the manufactured item. I can't provide code for this system because it is proprietary to the NRC.

Blackjack game in progress
Card Counting Hi-Lo Method Simulator

I designed a hi-lo card counting simulator that would test the relative frequency of winning in blackjack for various amounts of decks and configurations. This would determine if the house or the player has the edge in regards to the methodology as well as deck configuration.

Home Alarm System

I coded a home alarm system in C that utilized the Freescale/Motorola HCS12. The program involved arming the system using a keypad. When the system is armed by typing in the passcode the alarm can be tripped by tripping a sensor. This will activate an interupt that causes an alarm to sound. The alarm can be disarmed by typing in the same passcode. It also utilized a 7 segment display that showed the passcode when typed.
Capstone demonstration
Engineering Capstone Design Project

I started my capstone design project that involves helping those to use the computer screen using only portions of the face. The design involves using deep learning algorithms such as cascaded neural networks to trigger certain mouse events.
Microwave Amplifier Circuit
Microwave Amplifier Design

I have designed, simulated, built, and tested a microwave amplifier at 3.1 GHz frequency in a 50Ω system. To design the circuit, NI-AWR Microwave Office was utilized. The input and output matching networks were designed using open circuited shunt stubs since they can be easily fabricated and allow some tuning. I have calculated the maximum gain of the BJT from the given S parameters in the data sheet, ensured that the amplifier is stable over the entire useful bandwidth of the device, minimized S11 and S22, and maximized the bandwidth. The circuit was then fabricated with RT/Duroid 5880 with a dielectric thickness of 787.41µm. In the final step, I assembled and mounted the circuit on the microwave test jig and tested it with a VNA.
4 Element Linear Antenna Array
4 Element Microstrip Patch Linear Antenna Array

Utilized NI-AWR Microwave Office to design a microstrip patch antenna element and implemented a 4 element linear array with 5.2GHz frequency. The substrate used in the design is RT/Duroid 5880 with a dielectric thickness of 1.574mm. I have calculated, simulated, and measured the electric field in various planes of polarization and the S parameters. I maximized the input return loss at port 1 of the feed network to ensure that the power from the generator will enter the feed network and be available to the antenna patches. In addition to that I made sure that the array design was matched to 50 Ω with zero reactance, zero reflection, and full transmission.

PCB Design for Motor Control System

Utilized Altium to design 4 layers PCB layout for the brushless DC motor driver board for an electric vehicle. Completed calculations and design simulations to assess power needs and choose optimal components for the circuit. Developed applications and modifications for electronic properties used in components, products, or systems to improve techinical performance.
