Turkish Journal of Computer and Mathematics Education (TURCOMAT), 2021 These harmonics are higher than essential frequencies and cause Total Harmonics Distortion (THD) which increases the rms current and generates more warmth in the load. Numerous techniques are used to suppress the harmonics to limit the warmth in the load.

Programmable Flocks: Hierarchical Swarm Control via Dynamic Parameter Injection
Advanced Intelligent Systems, EarlyView.We present a method for the control of robot swarms which allows the shaping and the translation of patterns of simple robots (“smart particles”), using two types of devices. These two types represent a hierarchy: a larger group of simple, oblivious robots (which we call the workers) that is governed by simple local attraction forces and a smaller ...

Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites
Meteoritics &Planetary Science, EarlyView.Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.
