For example, a polygon has rotational as well as reflectional symmetries, all of which, together with the operation of composition, form what's called a finite group, because the polygon can be ...

An artificial spin ice array exploits two-dimensional chirality to take a step towards technology. The functionality of the micromagnetic array may be understood by analogy with a mechanical ratchet ...

Using ideas from Murskiǐ [3], Tokarz [4] and Wroński [7] we construct some strongly finite consequence operation having $2^{\aleph _{0}}$ standard strengthenings. In this way we give the affirmative ...

The Fisher-Yates shuffle (also known as the Knuth shuffle) is an algorithm for generating random permutations of a finite sequence. It's named after Ronald Fisher and Frank Yates, who first described ...

Abstract: This paper studies the unimodular sequence design with the finite alphabet case for a cognitive radar in order to achieve the desired auto-correlation. An iteration algorithm based on ...

Abstract: In order to suppress zero-sequence current (ZSC) for open-end winding surfaced permanent magnet synchronous machine (OEW-SPMSM) drives with single dc voltage source, many methods have been ...
