Design and Implementation of a 31-level Inverter Based on FPGA for Sustainable Energy Applications [PDF]

Iranian Journal of Electrical and Electronic Engineering
Artificial intelligence-based optimization algorithm was used to compute the switching angle values. In order to run the inverter with the lowest possible Total Harmonic Distortion (THD) value, it is suggested in this study to use an algorithm such as ...

Accuracy and Repeatability of Rolling Stock Current Distortion Tests for Interference to Signalling

Metrology
The testing of rolling stock for the assessment of disturbance in signalling circuits is considered with a focus on the measurement process and the selection of operating conditions. The definition of interference limits is briefly reviewed, but they are

The relationship between monopole harmonics and spinweighted spherical harmonics [PDF]

We compare two independent generalizations of the usual spherical harmonics, namely monopole harmonics and spin‐weighted spherical harmonics, and make precise the sense in which they can be considered to be the same.
