Abstract: In this paper, a comprehensive review is carried out of existing sparse arrays for direction-of-arrival (DOA) estimation of non-circular sources. We know that for DOA estimation of ...

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 ...

We’ll explore how Array’s integration of APA’s fixed-tilt and A-frame designs opens new possibilities in difficult terrains and why foundation choice is critical to structural resilience and long-term ...

Abstract: Sparse arrays offer economic advantages by reducing the number of antennas. However, directly utilizing the covariance matrix of sparse array signals for wideband beamforming may lead to the ...

Near-field focused antenna arrays have emerged as a critical technology for optimising electromagnetic energy delivery and imaging. By finely controlling the phases and amplitudes of individual ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Array to acquire APA Solar for $179M, expanding tracker-foundation solutions. Deal expected to lift adjusted EPS in year one, pre-synergies. The next correction is closer than you think. Find out how ...
