Euler e os números pentagonais
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ensino de Ciências Naturais e MatemáticaEnsino de Ciências Naturais e Matemática, 2011-10-26)
The present investigation includes a study of Leonhard Euler and the pentagonal
numbers is his article Mirabilibus Proprietatibus Numerorum Pentagonalium - E524.
After a brief review of the life and work of Euler, we analyze ...
Compaction and arching in tapped pentagon deposits
(Springer Verlag Berlín, 2008-11-12)
We simulate the process of compaction under vertical tapping for a two-dimensional system of particles deposited in a rectangular box. The particles consist in regular pentagons and our main objective is to analyze the ...

Pinning of ferromagnetic domains in interconnected pentagonal spin ice lattices
(2019)
The magnetization reversal process of interconnected pentagonal spin ice systems was investigated using micromagnetic simulations and experimental measurements. Five different systems were investigated, beginning with the ...
Promotion and evolution of sustainability performance measurement systems from a perspective of business process management: From a literature review to a pentagonal proposal
(2015-01-01)
Purpose – The purpose of this paper is to create a conceptual proposal that considers the relevant aspects to guide the promotion and evolution of corporate sustainability performance measurement systems (SPMSs) from a ...
Superconducting State of a Disk with a Pentagonal/Hexagonal Trench/Barrier
(Springer, 2014-01-01)
We study the influence of a pentagonal (hexagonal) trench or barrier on the superconducting properties of a perforated disk. Effects associated to the pinning (anti-pinning) force of the central hole and the trench (barrier) ...
