Watch a seamless cycle of takeoff, underwater cruise, and skyward reemergence in this student-built hybrid drone.

This project is an upgraded version of my previous design, a highly compact and robust animatronic eye mechanism which uses 3D printed components and an Arduino microcontroller. If you are able to get ...

Overview Chili3D is an open-source, browser-based 3D CAD (Computer-Aided Design) application built with TypeScript. It achieves near-native performance by compiling OpenCascade (OCCT) to WebAssembly ...

Sparse array design is used to help reduce computational, hardware, and power requirements compared to uniform arrays while maintaining acceptable performance. Although minimizing the Cramér-Rao bound ...

This paper explores the potential, challenges, and applications of near-field 3D spot beam focusing in advanced communication systems.
