My name is Ravi Dhaliwal and I am a physics student at the University of California, Los Angeles. I spend a lot of my time focused on engineering oriented projects ranging from software projects to launching model rockets. I aim to enter an industry where I can fully utilize my skillset when I graduate.
For the fall of 2023, I was the principal investigator for my teams proposal of implementing super capacitors into satellite propulsions systems to better collision avoidance.
From Summer 2022 to Winter 2023, I was involved in a research lab under Professor Venkatadriagaram focused on creating a low energy water filtration device. Specifically I worked on creating a venturi tube capable of producing a pressure drop of 30,000 pascals, enough to vaporize water.
I designed a rear wing using the NACA 4418 aerofoil design. The wing features two splitters at different angles of attack. I then simulated the downforce produced by the wing at various speeds using STAR CCM+.
I designed and fabricated a 3 foot long rocket using 3d printed plastic, fiberglass, and cardboard. With a custom avionics system that logged down position, acceleration, and orientation data, it reached an apogee of 1000m using a J425 rocket motor.
Using FFTW, I created a song detection program that is similar to Shazam. It generates a hash table of the most intense frequencies throughout a given song and compares that to input data to determine what song it most likely matches.
This project was focused on transcibing audio files to MIDI files that could be used in a DAW like FL Studio. To do this I utilized FFTW to construct a spectrogram of the song, logging the most intense frequencies throughout discrete chunks of the song. I then clamped these frequencies to the nearest neighbor frequency according to what key the song was in. Finally I am working on creating a machine learning algorithm that will accuratley detect whether a note is being pressed or unpressed based off of the songs intensity data
For r/Place 2023 I created a software that used hundreds of bot accounts to participate in the event as if they were actual users. To interact with the website I used the standard HTTP library included in .NET and I employed proxies to avoid IP bans. The bot software was multithreaded to ensure each worker could function in parrallel to each other.
