An extremal problem with applications to renewable energy production
(EDP Sciences, 2021)
Dynamic optimisation provides complex challenges for optimal solution, but greatly increases applicability when considering time dependent situations. In this work, a constrained dynamic optimisation problem is analysed ...

Field-design optimization with triangular heliostat pods
(American Institute of Physics, 2016-05)
In this paper the optimization of a heliostat field with triangular heliostat pods is addressed. The use of structures which allow the combination of several heliostats into a common pod system aims to reduce the high ...

Some existence and uniqueness results for a time-dependent coupled problem of the Navier-Stokes kind
(World Scientific, 1998)
In this paper, we consider some systems which are close to the instationary Navier-Stokes equations. The structure of these systems is the following: An (N +1)-dimensional equation for motion (including the incompressibility ...

An optimal control problem for a generalized Boussinesq model: The time dependent case
(Universidad Complutense de Madrid, 2007)
We consider an optimal control problem governed by a system of nonlinear partial differential equations modelling viscous incompressible flows submitted to variations of temperature. We use a generalized Boussinesq ...

Time and space parallelization of the Navier-Stokes equations
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2005)
In this paper, we will be mainly concerned with a parallel algorithm (in time and space) which is used to solve the incompressible Navier-Stokes problem. This relies on two main ideas: (a) a splitting of the main differential ...

On the controllability of the heat equation with nonlinear boundary Fourier conditions
(Elsevier, 2004-01-20)
In this paper we analyze the approximate and null controllability of the classical heat equation with nonlinear boundary conditions of the form ∂y ∂n + f(y) = 0 and distributed controls, with support in a small set. We ...

Continuous optimisation techniques for optimal aiming strategies in solar power tower plants
(PERGAMON-ELSEVIER SCIENCE LTD, 2019-01-01)
Optimising the aiming strategy is crucial for Solar Power Tower plants, in order to maximise the energy generated, whilst also preventing catastrophic damage to receiver components. In this work, a bi-objective ...

Sobre la aproximación numérica de un problema de control geométrico
(Universitat de Barcelona, 1982)
The purpose of this paper is to introduce a new method for solving an optimum design problem: determining the aerodynamic body of minimum-drag profile at constant velocity in a viscous incompressible fluid. The stationnary ...
