About K-Positivity Properties of Time-Invariant Linear Systems Subject to Point Delays
(Hindawi Publishing Corporation, 2007)
This paper discusses nonnegativity and positivity concepts and related properties for the state and output trajectory solutions of dynamic linear time-invariant systems described by functional differential equations subject ...
‘Neptune’ between ‘Hesperus’ and ‘Vulcan’: On descriptive names and non-existence
(Springer, 2005)
[EN]This work will focus on some aspects of descriptive names. The New Theory of Reference,
in line with Kripke, takes descriptive names to be proper names. I will argue in this paper that
descriptive names and certain ...
Constant mean curvature hypersurfaces with constant δ-invariant
(Hindawi Publishing Corporation, 2003)
We completely classify constant mean curvature hypersurfaces (CMC) with constant
δ-invariant in the unit 4-sphere S4 and in the Euclidean 4-space E4.
Geometric multiplicity margin for a submatrix
(Elsevier, 2002-07)
Let G be a square complex matrix with less than k nonconstant invariant factors. We find a complex matrix that gives an optimal approximation to G among all possible matrices that have more than or equal to k invariant ...
Design of a Sensor Based on Plastic Optical Fibre (POF) to Measure Fluid Flow and Turbidity
(MDPI, 2009-05)
Although many optical fibre applications are based on their capacity to transmit optical signals with low losses, it can also be desirable for the optical fibre to be strongly affected by a certain physical parameter in ...
Is a Small Monte Carlo Analysis a Good Analysis? Checking the Size, Power and Consistency of a Simulation-Based Test
(Springer, 2002)
In this paper we study the relationship between the number of
replications and the accuracy of the estimated quantiles of a distribution
obtained by simulation. A method for testing hypotheses on the quantiles
of a ...
An Analysis of English, Spanish and Basque Demonstratives in Narrative: a Matter of Viewpoint
(Universidad de Murcia, Servicio de Publicaciones, 2003)
[EN]This paper undertakes the study of the occurrence of non-corresponding demonstrative forms in Spanish, Basque and English in exactly the same linguistic context. It is proposed that the differenccs in the choice of the ...
Hospitalization for respiratory syncytial virus in the paediatric population in Spain
(Cambridge University Press, 2003-10)
The aim of this population-based retrospective study was to determine the incidence of hospitalization for community-acquired, laboratory-confirmed respiratory syncytial virus (RSV) infection in an unselected paediatric ...
Risk factors for hospitalization due to respiratory syncytial virus infection among infants in the Basque Country, Spain
(Cambridge University Press, 2006-06)
This study analysed the role of several risk factors for hospitalization due to community-acquired, respiratory syncytial virus (RSV) infection. The risk factors detected in infants hospitalized for RSV infection in the ...
Hospitalization rates for human metapneumovirus infection among 0- to 3-year-olds in Gipuzkoa (Basque Country), Spain
(Cambridge University Press, 2009-01)
Numerous studies have been published on human metapneumovirus (HMPV) infection, but few have been population based. The main aim of this study was to estimate the incidence rate of hospitalization for community-acquired ...
