Repository for Gravity Field Modeling and Recovery using Machine Learning Methods
A performance-effective program for gravity field calculation for layered ellipsoidal density model.
Streamline transportation planning with the Gravity Model's Python implementation. This repository offers a comprehensive README, user-friendly Python script, and practical examples, making it straightforward for users to implement and adapt the model to their specific urban planning scenarios.
The implementation of the Small Bodies Geophysical Analysis Tool (SBGAT)
Stochastic model of invasive zebra/quagga mussel spread as facilitated by boat traffic, built for QGIS
This project implements a gravity accelerator using Verilog and Vivado. It simulates the physics of gravitational acceleration, calculating velocity and position over time within a digital circuit environment. The project includes testbenches and waveform analysis to ensure accurate simulation and performance.
