Minimal non-abelian groups with an average condition on subgroups [PDF]

open access: yesJournal of Mahani Mathematical Research
For a finite group $G$, the average order   $o(G)$   is defined to be the average of all order elements in $G$. We say that $G$ satisfies the average condition if $o(H)\leq o(G)$ for all subgroups $H$ of $G$.

A Study on Centralizing Monoids with Majority Operation Witnesses

open access: yesScientific Annals of Computer Science, 2023
A centralizing monoid M is a set of unary operations which commute with some set F of operations. Here, F is called a witness of M . On a 3-element set, a centralizing monoid is maximal if and only if it has a constant operation or a majority ...

Finite element algorithms for nonlocal minimal graphs

open access: yesMathematics in Engineering, 2021
<abstract><p>We discuss computational and qualitative aspects of the fractional Plateau and the prescribed fractional mean curvature problems on bounded domains subject to exterior data being a subgraph. We recast these problems in terms of energy minimization, and we discretize the latter with piecewise linear finite elements.

Asymptotics for minimal overlapping patterns for generalized Euler permutations, standard tableaux of rectangular shape, and column strict arrays [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
A permutation $\tau$ in the symmetric group $S_j$ is minimally overlapping if any two consecutive occurrences of $\tau$ in a permutation $\sigma$ can share at most one element. B\'ona \cite{B} showed that the proportion of minimal overlapping patterns in

Euler Buckling and Minimal Element Length Constraints in Sizing and Shape Optimization of Planar Trusses

open access: yes, 2022
Structural optimization of trusses is a complex process and requires a realistic representation of the problem in order to achieve applicable results.

Minimal energy control of a nanoelectromechanical memory element [PDF]

open access: yes, 2012
The Pontryagin minimal energy control approach has been applied to minimise the switching energy in a nanoelectromechanical memory system and to characterise global stability of the oscillatory states of the bistable memory element.

Generic uniqueness of minimal configurations with rational rotation numbers in Aubry-Mather theory

open access: yesAbstract and Applied Analysis, 2004
We study (h)-minimal configurations in Aubry-Mather theory, where h belongs to a complete metric space of functions. Such minimal configurations have definite rotation number.

Analysis of content of heavy metals in grass used to feed cattle by Energy Disperse X-Ray Fluorescence Spectroscopy

open access: yesProspectiva, 2015
In this work, we show an easy and practical analytical method to quantify the content of heavy metals in grass used to feed cattle located in areas of high vehicle traffic flow.

Computational form-finding methods for fabric structures [PDF]

open access: yes, 2008
Form-finding is a process that determines the surface configuration of a fabric structure under prestress. This process can be carried out using a variety of numerical methods, of which the most common are (a) transient stiffness, (b) force density, and (
