About the properties of a modified generalized Beverton-Holt equation in ecology models
(Hindawi Publishing Corporation, 2008)
This paper is devoted to the study of a generalized modified version of the well-known Beverton-Holt equation in ecology. The proposed model describes the population evolution of some species in a certain habitat driven ...
On minimal realizations and minimal partial realizations of linear time-invariant systems subject to point incommensurate delays
(Hindawi Publishing Corporation, 2008)
This paper investigates key aspects of realization and partial realization theories for linear time-invariant systems being subject to a set of incommensurate internal and external point delays. The results are obtained ...
Subcutaneous fat composition of youthful and mature Canadian beef: emphasis on individual conjugated linoleic acid and trans-18:1 isomers
(Agricultural Institute of Canada, 2008-12)
[EN]A comprehensive evaluation of the fatty acid composition of subcutaneous adipose tissue from beef cattle produced in western Canada was undertaken to determine if the current Canadian grading system is able to distinguish ...
Model-matching-based control of the Beverton-Holt equation in Ecology
(Hindawi Publishing Corporation, 2008)
Beverton-Holt equation of Ecology has a prescribed solution. The way used to achieve the tracking objective is the design of a carrying capacity through a feedback law so that the prescribed reference sequence, which defines ...
Stability Results for Switched Linear Systems with Constant Discrete Delays
(Hindawi Publishing Corporation, 2008)
This paper investigates the stability properties of switched systems possessing several parameterizations (or configurations) while being subject to internal constant point delays. Some of the stability results are formulated ...
On the Global Asymptotic Stability of Switched Linear Time-Varying Systems with Constant Point Delays
(Hindawi Publishing Corporation, 2008)
This paper investigates the asymptotic stability of switched linear time-varying systems with constant point delays under not very stringent conditions on the matrix functions of parameters. Such conditions are their ...
About Robust Stability of Dynamic Systems with Time Delays through Fixed Point Theory
(Hindawi Publishing Corporation, 2008)
This paper investigates the global asymptotic stability independent of the sizes of the delays of linear time-varying systems with internal point delays which possess a limiting equation via fixed point theory. The error ...
About the stability and positivity of a class of discrete nonlinear systems of difference equations
(Hindawi Publishing Corporation, 2008)
This paper investigates stability conditions and positivity of the solutions of a coupled set of nonlinear difference equations under very generic conditions of the nonlinear real functions which are assumed to be bounded ...
Risk factors for dementia in the epidemiological study of Munguialde County (Basque Country-Spain)
(BioMed Central, 2008-10-15)
Background: Prevalence of degenerative dementias and dementias associated with cerebrovascular disease is increasing. Dementia is one of the most significant public health problem. In recent years, the role of vascular ...
C. C. Uhlenbeck´s work on the Basque language: (In memory of Rudolf P.G. de Rijk, 1937-2003)
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2008)
C. C. Uhlenbeck worked on a wide variety of languages, but Basque is probably the language that was the most stable research interest throughout his career.In recent years, many unknown facts about Uhlenbeck's life have ...
