A powerful storm turns a spinning windmill into a stunning water vortex. An incredible weather moment showcasing the raw force and beauty of nature. #storm #extremeweather #weather #stormchasing ...

Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...

This project simulates the 3D attitude control of a quadcopter using PID controllers in MATLAB. The simulation numerically integrates the quadcopter’s nonlinear equations of motion using the ODE45 ...

Abstract: As a practical and versatile unmanned aerial vehicle, quadrotor drones demonstrate significant application value across multiple fields. This paper first systematically reviews the current ...

ABSTRACT: The main energy source used to heat water in rural Cameroonian households is wood. The use of wood as an energy source (wood fuel) has negative environmental and health impacts, which can be ...

End-to-end processing chain: DL-SCH encoding → PDSCH → Precoding → CP-OFDM → CDL/TDL Channel → Receiver (timing sync, demodulation, channel estimation, decoding) with CSI feedback and HARQ ...

Abstract: Aiming at the problem that the scattering characteristics of high-modal electromagnetic vortex waves on complex composite targets are still unclear, this paper systematically investigates ...

Simulation of water flow in the soil in semiarid regions is fundamental for managing scarce water resources. Aiming for more accurate results, the sensitivity analysis (SA) of the hydrodynamic ...
