Large sparse linear systems arise in diverse fields such as structural engineering, fluid dynamics, network analysis and machine learning. Direct factorisation techniques often become impractical for ...

Abstract: Sparse linear arrays serve as the fundamental basis for sparse signal processing and have demonstrated remarkable direction-of-arrival (DOA) estimation performance. Due to the merit of ...

Abstract: Sparse arrays offer a promising solution for reducing the data volume required to reconstruct ultrasound images, making them well-suited for portable and wireless devices. However, the ...

So, you’ve got a HackerRank test coming up, huh? It’s pretty common these days, with lots of companies using it to see if you can code. It can feel a bit daunting, but honestly, it’s just another ...

Neutral-atom arrays are a rapidly emerging platform to create quantum computers. In a foundational study led by graduate students Aaron Holman and Yuan Xu from the Will and Yu labs, respectively, the ...

Array Technologies has acquired APA Solar Racking, bringing together two major players in fixed and tracking solar mounting structures. With APA’s fixed-tilt systems and its well-known A-frame ...
