A modified Fourier series-based solution with improved rate of convergence for two-dimensional rectangular isotropic linear elastic solids
(SAGE Publications, 2021-07)
This paper presents a new displacement solution based on a Modified Fourier Series (MFS) for isotropic linear elastic solids under plane strain or plane stress states subject to continuous displacement and traction boundary ...
Recursive linear estimation for general discrete-time descriptor systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
This paper considers the optimal linear estimates recursion problem for discrete-time linear systems in its more general formulation. The system is allowed to be in descriptor form, rectangular, time-variant, and with the ...
Transient heat diffusion problems with variable thermal properties solved by generalized integral transform technique
(2014-01-01)
In this work, studies of two-dimensional transient heat diffusion problems in domains of rectangular and elliptical geometries, submitted to boundary conditions of first kind, were carried out. For the problem formulation, ...
Plasmons and the electromagnetic response of nanowires
(2010)
We present a theory of the nature of plasmons in nanowires along with the response of such systems to a
spatially uniform applied electric field in the plane perpendicular to the symmetry axis of the wire. We confine
our ...
El problema de Cauchy asociado a una generalización de la ecuación Zakharov-Kuznetsov sobre el cilindro
(Universidad Nacional de ColombiaBogotá - Ciencias - Doctorado en Ciencias - MatemáticasDepartamento de MatemáticasFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021-07)
In this work, we study questions related to the local well-posedness for the initial value problem associated to the partial differential equation,
u_{t} − ∂_{x}(D_{x}^{α+1}u ± D_{y}^{β+1}u) + u^{p}u_{x} = 0, where 0 ≤ ...
PRACTICAL LAND GRADING BASED ON LEAST SQUARES.
(1986-05-01)
Practical methods for land grading design of a plane surface for rectangular and irregularly shaped fields based on a least squares analysis are presented. The least squares procedure leads to a system of three linear ...
