Dimensionalidade da capacidade económica nas comarcas galegas
(Universidade de Santiago de Compostela, 2000)Neste artigo o obxectivo xeral que se establece é realizar unha análise exploratoria dun conxunto suficientemente amplo de variables que, nun primeiro momento, están relacionadas coa capacidade económica a nivel comarcal. ... -
Sistemas de control suplementario da contaminación atmosférica
(Universidade de Santiago de Compostela, 2002)Os sistemas de control suplementario da contaminación atmosférica, baseados en efectuar cambios nas condicións de operación para reduci-las emisións atmosféricas en condicións meteorolóxicas adversas, permiten evita-la ... -
Benestar socioeconómico dos concellos galegos: unha aproximación á súa medida
(Universidade de Santiago de Compostela, 2003)O obxectivo final deste traballo é chegar a unha comparación territorial entre os concellos galegos no referente ó nivel ou calidade de vida ou, cando menos, á súa aproximación. Para este propósito empregarase o método ... -
Existence and uniqueness of solutions of higher-order antiperiodic dynamic equations
(SpringerOpen, 2004)We prove existence and uniqueness results in the presence of coupled lower and upper solutions for the general nth problem in time scales with linear dependence on the ith Δ- derivatives for i = 1, 2, . . . ,n, together ... -
Stability of periodic solutions of first-order difference equations lying between lower and upper solutions
(SpringerOpen, 2005)We prove that if there exists α ≤ β, a pair of lower and upper solutions of the first-order discrete periodic problem Δu(n) = f (n,u(n)); n ∈ IN ≡ {0, . . . ,N −1}, u(0) = u(N), with f a continuous N-periodic function ... -
Existence of extremal solutions for quadratic fuzzy equations
(Hindawi, 2005)Some results on the existence of solution for certain fuzzy equations are revised and extended. In this paper, we establish the existence of a solution for the fuzzy equation , where , , , and are positive fuzzy numbers ... -
Basic properties of Sobolev's spaces on time scales
(SpringerOpen, 2006)We study the theory of Sobolev's spaces of functions defined on a closed subinterval of an arbitrary time scale endowed with the Lebesgue Δ-measure; analogous properties to that valid for Sobolev's spaces of functions ... -
Existence results for φ-Laplacian boundary value problems on time scales
(SpringerOpen, 2006)This paper is devoted to proving the existence of the extremal solutions of a φ-Laplacian dynamic equation coupled with nonlinear boundary functional conditions that include as a particular case the Dirichlet and multipoint ... -
Analysis of an SIR Epidemic Model with Pulse Vaccination and Distributed Time Delay
(Hindawi, 2007)Pulse vaccination, the repeated application of vaccine over a defined age range, is gaining prominence as an effective strategy for the elimination of infectious diseases. An SIR epidemic model with pulse vaccination and ... -
Permanence and Periodic Solution of Predator-Prey System with Holling Type Functional Response and Impulses
(Hindawi, 2007)We considered a nonautonomous two dimensional predator-prey system with impulsive effect. Conditions for the permanence of the system and for the existence of a unique stable periodic solution are obtained. -
The Monotone Iterative Technique for Three-Point Second-Order Integrodifferential Boundary Value Problems with p-Laplacian
(Springer, 2007)A monotone iterative technique is applied to prove the existence of the extremal positive pseudosymmetric solutions for a three-point second-order p-Laplacian integrodifferential boundary value problem. -
A nonparametric approach to the estimation of lengths and surface areas
(Institute of Mathematical Statistics, 2007)The Minkowski content L0(G) of a body G⊂ℝd represents the boundary length (for d=2) or the surface area (for d=3) of G. A method for estimating L0(G) is proposed. It relies on a nonparametric estimator based on the information ... -
