Abstract: A microstrip dual-split-ring antenna array for fifth-generation (5G) millimeter-wave dual-band applications is presented in this letter. The microstrip dual-split-ring structure is adopted ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible. Sometime in the fall of 2021, Andrew ...

The array_split package provides the means to partition an array (or array shape) using any of the following criteria: Per-axis indices indicating the cut positions. Per-axis number of sub-arrays.

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...

Given the current ffi behaviour (aka "rechunk everything into Array"), there's one part missing from Python API that would otherwise allow for some workarounds if you need some control over rechunking ...

Abstract: This paper presents a 13-b C-2C split-array (SA) multiphase switched-capacitor power amplifier (SAMP-SCPA) implemented in 65-nm CMOS. The SAMP-SCPA was ...

A Raytheon developed Lower Tier Air and Missile Defense Sensor, or LTAMDS. The Army has received six prototypes of the future missile defense radar and has begun critical testing of the system. (Photo ...
