In this paper we study an inverse problem for a quasi-linear ordinary differential equation with a monotonic weight in the half-line. First, we find the asymptotic behavior of the singular eigenvalues, and we obtain a ...

In this paper we study an inverse problem for weighted second order Sturm-Liouville equations. We show that the zeros of any subsequence of eigenfunctions, or a dense set of nodes, are enough to determine the weight. We ...

In this work we analyze a nonlinear eigenvalue problem for the p-Laplacian operator with zero Dirichlet boundary conditions. We assume that the problem has a potential which depends on the eigenvalue parameter, and we show ...

En esta tesis centramos nuestra atención en la ecuación de Sturm-Liouville de segundo orden -u''= λρ(x)u, x ∈ (0,1), con cierta condición de borde homogénea. Estudiamos la densidad asintótica de los ceros de las autofunciones ...

This brief briefly addresses the problem of power flow solution for direct-current (dc) networks with radial configuration and constant power loads (CPLs). It proposes a novel iterative method based on the upper triangular ...

In this paper a technique for simultaneous untangling and smoothing of meshes is presented. Itis based on an extension of an earlier mesh smoothing strategy developed by the authors and used to solve the computational mesh ...

This work presents an analysis of the dynamic behavior of a structure with four degrees of freedom through application of the Mode-Superposition Method. For the determination of modes to vibrate and natural frequencies ...

En este trabajo se describe un modelo para el análisis de transitorios electromagnéticos en líneas de transmisión basado en la solución de las Ecuaciones del Telegrafista en el dominio de la frecuencia (espacial y ...
