Algebraic Limit Cycles in Piecewise Linear Differential Systems
(World Scientific Publ Co Pte Ltd, 2018-03-01)
This paper is devoted to study the algebraic limit cycles of planar piecewise linear differential systems. In particular, we present examples exhibiting two explicit hyperbolic algebraic limit cycles, as well as some ...
Límites y control a la reforma constitucional en México
(2007)
The limits to constitutional reform/amendments are, at all times, a highly topical subject in constitutional law because of the acts of arbitrariness likely to be committed by the holders of power through modifications to ...
Los límites en la arquitectura : tipos de límites arquitectónicos y su relación entre sí, en el barrio Fenicia.
Este documento nace como una puesta espacial en función del límite. Posterior a ello por
se toma la decisión de identificar tres tipos de límites que definen los espacios
arquitectónicos y sus relaciones entre sí. ...
Method for determination of flammability limits of gaseous compounds diluted with N2 and CO2 in air
(2018-08-15)
The present work studies the flammability limits of combustible–diluent–air mixtures at 25 °C and 1 atm pressure. The diluent species, considered in this study, were nitrogen and carbon dioxide. A factor called kFL was ...
Efeito do enriquecimento de nutrientes na biomassa fitoplanctônica no reservatório Boqueirão de Parelhas/RN
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Ambiental, 2019-11-11)
Over the years, aquatic ecosystems has been significantly altered due to the multiple environmental impacts of anthropogenic activities. Excessive nutrient enrichment (N and P) and the consequent increase in primary ...
Limit Cycles Bifurcating from a Period Annulus in Continuous Piecewise Linear Differential Systems with Three Zones
(World Scientific Publ Co Pte Ltd, 2017-02-01)
We study a class of planar continuous piecewise linear vector fields with three zones. Using the Poincare map and some techniques for proving the existence of limit cycles for smooth differential systems, we prove that ...
