Data Envelopment Analysis (DEA) developed by A. Charnes, W Cooper and E. Rhodes, is a non-parametric method, based on linear programming. DEA is used to measure the productivity and the relative efficiency of units of ...

The search for novel forms to generate electricity, renewable and clean, is a priority for today’s society. Renewable energy resources exploited and exploitable in each place are: the ability to produce biomass, position ...

The Euler-Poisson-Darboux equation is a reversible singular partial differential equation, which includes a free parameter k. We take a noisy image as initial data and consider the initial value problem associated for the ...

Biodiesel is an environmental alternative to diesel. In its production process, it is necessary to mix alcohols and oils, inmiscible fluids. Ultrasonic mixing creates cavities or bubbles that implode (phenomenon during ...

The purpose of this thesis is to develop a new mathematical model for the bend- ing of thin elastic plates with microstructure. Our approach is based on a generalization of the classical Reissner plate theory, which takes ...

The numerical solutions of Partial Differential Equations calculated from a finite difference scheme or finite element scheme generally present errors in amplitude, due to dissipation, and errors in phase due to dispersion. ...

The scope of this thesis investigation is to obtain an approximate numerical solution to the nonlinear one-dimensional Kuramoto-Sivashinsky partial differential equation. The Gaussian wave has been successfully applied to ...

In this work we are considering the identification problem related to a linear system. There are many linear systems for which experimentation results in complicated and costly tasks, but there are many other linear systems ...

Dado un conjunto de datos sobre un cuerpo finito Fq, queremos encontrar una función que interpole tales datos. Esta función se puede obtener por ingeniería reversa y es de la forma f = (f1, f2, ..., fn) : Fn −→ Fn donde ...
