Abstract: This correspondence studies the design of beam hopping (BH) pattern for satellite communication systems with hybrid analog-digital precoding. We investigate the transmit power minimization ...
Abstract: Near-field communications present new opportunities over near-field channels, however, the spherical wavefront propagation makes near-field signal processing challenging. In this context, ...
Support vector regression can predict numeric values effectively, and this article shows how to implement and train a kernel SVR model in C# using stochastic sub-gradient descent.
A research team at the University of Sharjah tested 30 small-scale cement mortar beams reinforced with 3D printed polylactic acid (PLA) profiles, and found that surface geometry was the dominant ...
College of Information and Communication Engineering, Harbin Engineering University, Harbin, China. MTI band-stop filter as a “single channel”, followed by detection is relatively simple. When the ...
A team of scientists from Oak Ridge National Laboratory, Cleveland Clinic and IBM has calculated nine molecular ...
Spectrum Control has introduced the Weinschel™ 8401-16E 16×16 Butler Matrix, a passive beamforming network for MIMO systems ...
Matrix structures don’t work on their own. The work is less about control and more about integration, often without formal ...
Decades ago, Paul Erdős used randomness to illuminate the vast and weird world of networks. Now mathematicians are making his ...
How the proteins in our bodies bind together to form protein complexes plays a critical role in numerous cell functions—staving off diseases, for instance, or transporting ions across cell membranes.
