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 ...

Abstract: This paper introduces a linear slot antenna array based on an empty substrate integrated waveguide at 28 GHz. The proposed antenna offers the advantages of reduced weight and fabrication ...

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 ...

Building on windows 10, using visual studio 2019 developer terminal with admin privileges', i built/installed ros2 foxy via the aka.ms way here the package "rosidl_generator_cpp" fails and gives this ...

ValueError: failed to initialize intent (inout) array -- expected elsize=8 but got 4 #77 New issue Closed STAR-811 ...

An array is a special type of variable that can hold more than one value at a time. A list is a data type that allows the storage of multiple values, or items, in one variable. A dictionary uses a key ...

Abstract: This paper introduces a planar 4 × 4 slot antenna array based on Empty Substrate Integrated Waveguide at 28 GHz. The proposed antenna offers reduced weight and fabrication cost as well as ...
