First, the payload requirements and problems faced by traditional multi-beam antenna are described. The user beam of the VHTS payload system mainly uses Ka-band multi-beam antenna for a large range of ...

Microscope images could be obtained much more quickly -- rather than one pixel at a time -- thanks to a new imaging method for neutral atomic beam microscopes. It could ultimately lead to engineers ...

Abstract: The aim of this paper is to investigate a direct numerical method for solving a class of a fractional variational problem (FVP). The fractional derivative in the FVP is in the Caputo sense.

This paper considers the sparse generalized eigenvalue problem (SGEP), which aims to find the leading eigenvector with at most $k$ nonzero entries. SGEP naturally ...
