A comparison between the modeling of a reciprocating compressor using artificial neural network and physical model
Elsevier (2015)This article presents the development, validation, and comparison of two methods for modeling a reciprocating compressor. Initially, the physical mode is based on eight internal sub-processes that incorporate infinitesimal ... -
A simplified black-box model oriented to chilled water temperature control in a variable speed vapour compression system
Elsevier (2011-02)The aim of this work is to propose a black-box model to accurately predict the chilled water temperature dynamic response of a vapour compression chiller. The model is oriented to be of value in determining an adequate ... -
Adapting concurrency throttling and voltage–frequency scaling for dense eigensolvers
Springer Verlag (2015)We analyze power dissipation and energy consumption during the execution of high-performance dense linear algebra kernels on multi-core processors. On top of this analysis, we propose and evaluate several strategies to ... -
Application of Compromise Programming to a semi-detached housing development in order to balance economic and environmental criteria
Palgrave Macmillan (2013)European Energy Performance of Buildings Directives DE promote energy efficiency in buildings. Under these Directives, the European Union States must apply minimum requirements regarding the energy performance of buildings ... -
Comparative study of transcritical vapor compression configurations using CO2 as refrigeration mode base on simulation
Elsevier (2013-03)Despite of the excellent efficiency of the CO2 transcritical cycle in heat pump mode, there is a loss of efficiency in refrigeration mode compared with the subcritical vapor compression cycle with HFC refrigerants. This ... -
Energy efficiency in the European Union: What can be learned from the joint application of directional distance functions and slacks-based measures?
Elsevier (2014-11-01)Over the last few years concerns have increased about the energy mix in many countries. These concerns have been of greater magnitude for countries with a common energy regulation such as European Union (EU) member states. ... -
El Mercado Único. La Europa sin Fronteras Interiores: Energía y Medio Ambiente. Universidad Politécnica de Madrid
Universidad Politécnica de Madrid (1992)Ciclo de conferencias sobre el Mercado Único dentro de la Acción Institucional'93 celebrado en la Universidad Politécnica de Madrid y presidido por el Secretario de Estado para las CC.EE, D. Carlos Westendorp junto con ... -
On the dynamics of eco-efficiency performance in the European Union
Elsevier (2016-02)This paper evaluates the evolution of environmental performance in the context of the European Union (EU), over the period 1993–2010. The context is particularly relevant, due to the traditionally high concerns of the EU ... -
QM/MM Calculations Suggest a Novel Intermediate Following the Proton Abstraction Catalyzed by Thymidylate Synthase
American Chemical Society (2013-03-07)The cleavage of covalent C–H bonds is one of the most energetically demanding, yet biologically essential, chemical transformations. Two C–H bond cleavages are involved in the reaction catalyzed by thymidylate synthase ... -
Rehabilitación energética de edificio de viviendas en la Vall d'Uixó
Universitat Jaume I (2015-06-18)El presente proyecto final de grado trata sobre la rehabilitación energética de un edificio de viviendas construido en el año 1984 y situado en la localidad de La Vall d'Uixó ubicada en la Plana Baja de la provincia ... -
Stability numbers in K-contact manifolds
Elsevier (2008)The aim of this paper is to study the stability of the characteristic vector field of a compact K-contact manifold with respect to the energy and volume functionals when we consider on the manifold a two-parameter variation ...
