This paper gives sufficient conditions for the practical and finite time stability of of a particular class of linear discrete time delay systems. () () () 0 1 1 1 k A k A k + = + − x x x. When we consider the finite time stability concept, these new, delay independent conditions are derived using an approach based on the Lyapunov – like functions. When the practical and attractive practical st...

The derivative feedback is a classical but representative means in the design of control systems, and for practical reasons it is often replaced by its difference approximation. As the resulting closed-loop system involves a time-delay, it does not necessarily preserve stability however accurate the approximation is. Following the terminology of Palmor (1980), it may be said that the practical ...

In 2008, the Ontario Long Term Care Association was awarded funding from HealthForceOntario to assist with its nursing recruitment strategy based on research it had initiated in 2007. The research goal was to understand the career motivations and perceptions of students enrolled in registered nursing (RN) and registered practical nursing (RPN) programs in Ontario to develop and test a message t...

This paper investigates the stability problem of a class of discrete-time singularly perturbed Tagagi–Sugeno (T-S) fuzzy models. Stability conditions of reduced slow models, based on the use of Borne and Gentina practical stability criterion and matrices in the arrow form, are developed and compared with those concerning the initial singularly perturbed T-S system. The obtained results are prac...

The practical stability of positive fractional discrete-time linear systems is addressed. It is shown that: 1) the positive fractional systems are unstable if at least one diagonal entry of the system matrix is greater one, 2) checking of the practical stability of the systems can be reduced to checking of the asymptotic stability of corresponding positive linear systems. The considerations are...

the objective of this research was to study genotype×environment interaction and to evaluate stability analysis of grain yield in chickpea genotypes under rainfed condition. experimental material was comprised of 17 genotypes with the experiments carried out in rcbd of four replications at kermanshah, lorestan, ilam, gachsaran and gorgan research stations during the two years of 2003-2004. the ...
