Repository for Gravity Field Modeling and Recovery using Machine Learning Methods
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.
A performance-effective program for gravity field calculation for layered ellipsoidal density model.
The implementation of the Small Bodies Geophysical Analysis Tool (SBGAT)
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.
