Abstract: In this article, a 3D geometry-based millimeter-wave channel model is proposed for reconfigurable intelligent surface (RIS)-assisted high-speed train communications. Remarkably, the RIS is ...
Abstract: Communication objectives with high mobility bring severe Doppler shifts, causing the inter-carrier interference of orthogonal frequency division multiplexing (OFDM) system, which raises the ...
When Alfa Romeo tried to reinvent itself as a premium global brand in the mid-2010s, it surprised with an early halo sport sedan in the form of the spectacular Giulia Quadrifoglio. That model was ...
3D models of Lightning McQueen and Jackson Storm have been uploaded to AirShaper's CFD analysis site, which you can play with on your own computer. AirShaper is a cloud-based CFD design tool. If ...
Organic cathodes have long been sought after for safe, sustainable, and recyclable energy storage, yet their development has been hampered by solubility, low voltage, and poor conductivity. In this ...
DeepSeek-AI released 3B DeepSeek-OCR, an end to end OCR and document parsing Vision-Language Model (VLM) system that compresses long text into a small set of vision tokens, then decodes those tokens ...
