My ultimate goal is to expand my understanding on the durability and efficiency of systems that promise to respond to the current environmental degradation. Focussing towards my goal, I work towards specalizing in Mechatronics and Physical Systems during my graduate degree program at University of Waterloo, Ontario, Canada.

As an undergraduate, at the Vellore Institute of Technology, I worked on autonomous trash segregation contributing towards waste management and public health using advanced image processing techniques. I am an avid cricket and e-sports enthusiast who also enjoys travelling and hiking.

Projects

Stock Market Prediction

Tools: R Studio
Description: The main objective of the project was to forecast the stock prices of a company (Apple) with the available data by building an ARIMA model. Considering that the data consisted mostly of Open, High, Low, Closing or OHLC, our model was designed to be a univariate time series.

Infectious Disease Surveillance using Time Series

Tools: R Studio
Description: The project focused on the practical aspects of using ARIMA (autoregressive, integrated, moving average) time series modelling in the surveillance of reportable infectious diseases, with a focus on the widely available SSS1 package from the Centers for Disease Control and Prevention. ARIMA modelling requires the following steps: time series selection, series transformations, model selection, param‑ eter estimation, forecasting, and forecast updating.

Route Planning with Real‑time Traffic Predictions

Tools: R Studio
Description: A system for individual trip planning was designed, that effectively plans the route considering the future traffic haz‑ ards. Conditioning spatial regression on intermediate predictions of a discrete probabilistic graphical model allowed for the simultaneous incorporation of historical data, streamed online data, and a rich dependency structure.

Design of LQR Servo Controller

Tools: Matlab and Simulink
Description: The goal was to perform a steady coordinated turn for an aircraft. A controller that commands a steady turn by going through a 60° roll was designed. In addition, the design was made such that the pitch angle (𝜃) stayed close to zero.

LQR Design for Vehicle Suspension System

Tools: Matlab and Simulink
Description: Designed a Linear Quadratic Regulator (LQR) control system for the vehicle suspension system is the recommended approach. Based on the condition and inputs of the vehicle, the LQR system is a feedback control system that improves suspen‑ sion performance. The LQR system will be made up of a state observer that will gauge the condition of the car and a feedback controller that will regulate the suspension system in accordance with the gauged condition.

Optisystem based CATV performance enhancement

Tools: Python, Optisystem
Description: This project explains about the use of erbium doped amplifiers in the enhancement of Cable television

Railway Track quality

Tools: Matlab
Description: This project displayed the methods through which defects can be detected in a railway track with the help of image processing

Origami robot

Tools: Python, Arduino IDE
Description: The main concept behind this project is that the robot possesses the ability to fold itself with the help of electromagnetic force.

Wireless forest fire detection system

Tools: Arduino Uno
Description: The project focuses on the development of a Wireless Sensor Network-based Forest Fire Detection System that comprises basic RF modules for wireless communication and solar energy harvesting system. The system will detect the presence of a fire using temperature, gas and flame sensors and transmit a message to the base station with the help of a Zigbee module, it will also trigger the controller which will enable the process of extinguishing the fire.

Image compression and decompression using LZW coding

Tools: Python
Description: The idea of the compression algorithm is the following: As the input data is being processed, a dictionary keeps a correspondence between the longest encountered words and a list of code values. The words are replaced by their corresponding codes and so the input file is compressed. Therefore, the efficiency of the algorithm increases as the number of long, repetitive words in the input data increases.

Holistic HealthCare

Tools: C, ESP32-PICO-D4 microcontroller
Description: The main features of this project are detection of sleepwalking, high heart rate, high body temperature and intimation. In an emergency, it must intimate a family member about the patient by making a call. The accelerometer data is used by the microcontroller to calculate the number of steps taken by the user, their body temperature and pulse rate. If the values exceed a particular threshold, then the family member gets notified.

Bluetooth controlled Home automation System

Tools: C, Proteus
Description: The project consisted of a virtual simulation of the devices which can be controlled by Bluetooth through our phone such as AC, Light etc. All the features had to be done manually and not with the help of a PIR sensor.
