Stability of the logistic population model with generalized piecewise constant delays

Retarded Differential Equations with Piecewise Constant Delays

Profound and close links exist between functional and functional differential equations. Thus, the study of the first often enables one to predict properties of differential equations of neutral type. On the other hand, some methods for the latter in the special case when the deviation of the argument vanishes at individual points have been used to investigate functional equations [ 11. Functio...

Dynamics of a harvested logistic type model with delay and piecewise constant argument

In this paper, a harvested logistic equation with delay and piecewise constant argument of generalized type is addressed. Both discrete and piecewise constant delays are incorporated into the logistic equation for investigation. Existence, boundedness of positive solutions and permanence are studied for the proposed logistic model. c ⃝2015 All rights reserved.

Determination of the Stability Constant of Vanadium (V) with Alaine

Formation equilibria of dioxy vanadium (V) complex with alanine in acidic media (pH<2.3) has been investigated potentiometrically and spectrophotometrically. In this condition the 1:1 complex has the formula VO2Y, where Y¯ represent the fully dissociated aminocarboxylate anion. The stability constant of VO2Y was determined as log KVO2Y=11.32±<e...

Discrete delays and piecewise constant argument in neuronics

The literature of neural network models has been intensively established in the last two decades. As one of the most interested topics of studying the dynamics of a neural networks system, parametrical-induced, dynamical stability draws a vast majority of attention in the recent years of researches. For examples, in their recent study, Akhmet & Yilmaz 2009 considered the Hopfield type neural ne...
