Optimal control of infinite dimensional bilinear systems: application to the heat and wave equations
(Springer Verlag, 2018)
In this paper we consider second order optimality conditions for a bilinear optimal control problem governed by a strongly continuous semigroup operator, the control entering linearly in the cost function. We derive first ...
Uses of equations and methods to estimate the basal energetic cost and the total energetic cost of adults that practice physical activities: a case studyUtilização de diferentes equações e métodos a estimativa do gasto energético basal e total de praticantes de atividade física adultos
(Inst brasileiro pesquisa & ensino fisiologia exercicio-ibpefex, 2016)
Introduction and Aims: The BEC (Basal Energy Cost /GEB) is the energy used by every cell in the human body for the maintenance of its operation. The Energy Expenditure with Physical Activities (GAF), added to the GEB and ...
An efficient hybrid pseudospectral/finite-difference scheme for solving the TTI pure P-wave equation
(Journal of Geophysics and Engineering, 2013)
The pure P-wave equation for modelling and migration in tilted transversely isotropic (TTI) media has attracted more and more attention in imaging seismic data with anisotropy. The desirable feature is that it is absolutely ...
AVERAGE CONTINUOUS CONTROL OF PIECEWISE DETERMINISTIC MARKOV PROCESSES
(SIAM PUBLICATIONS, 2010)
This paper deals with the long run average continuous control problem of piecewise deterministic Markov processes (PDMPs) taking values in a general Borel space and with compact action space depending on the state variable. ...
Thermoeconomic analysis method for optimization of combined heat and power systems. Part I
(Elsevier B.V., 2003-01-01)
This article presents a thermoeconomic analysis of cogeneration plants, applied as a rational technique to produce electric power and saturated steam. The aim of this new methodology is the minimum Exergetic Production ...

Estimating the gravity equation with the actual number of exporting firms
(Universidad de Chile. Facultad de Economía y Negocios, 2013-06)
To estimate correctly the effect of variable trade costs on firms’ exports, the
gravity equation should control for the number of firms that participate in foreign
markets. Due to the absence of these data, previous ...
Thermoeconomic analysis method for optimization of combined heat and power systems - part II
(Elsevier B.V., 2004-01-01)
In this paper, a thermoeconomic functional analysis method based on the Second Law of Thermodynamics and applied to analyze four cogeneration systems is presented. The objective of the developed technique is to minimize ...

Analysis of the stability and dispersion for a Riemannian acoustic wave equation
(ELSEVIER SCIENCE INC, 2019-01-15)
The construction of images of the Earth's interior using methods as reverse time migration (RTM) or full wave inversion (FWI) strongly depends on the numerical solution of the wave equation. A mathematical expression of ...
