Scalability of the Muscular Action in a Parametric 3D Model of the Index Finger
Springer Verlag (2008)A method for scaling the muscle action is proposed and used to achieve a 3D inverse dynamic model of the human finger with all its components scalable. This method is based on scaling the PCSA (physiological cross-sectional ... -
Flow Structure of Subcooled Boiling Water Flow in a Subchannel of 3 x 3 Rod Bundles
Atomic Energy Society of Japan (2008)In this paper, the interfacial flow structure of subcooled water boiling flow in a subchannel of 3 x 3 rod bundles is presented. The 9 rods are positioned in a quadrangular assembly with a rod diameter of 8.2mm and a ... -
Activity modelling in a collaborative ceramic tile design chain: an enhanced IDEF0 approach
Springer-Verlag (2008)Explicit descriptions of should-be and to-be activities and processes are key elements in implementing industrial projects aimed at improving new-product development (NPD) processes, especially when e-collaboration utilities ... -

Las declaraciones de impacto ambiental en estaciones depuradoras de aguas residuales
TIASA (2008)Se hace patente el principio de prevención como guía de la política medioambiental, estableciendo en las DIAs la adopción de todas aquellas medidas que eviten impactos. La minimización, que se muestra en la necesidad de ... -
Experimental evaluation of the energy efficiency of a CO2 refrigerating plant working in transcritical conditions
(2008)This work presents the experimental evaluation of the energy efficiency and optimal gas-cooler pressures of a single-stage refrigerating plant working with carbon dioxide as refrigerant in transcritical conditions. The ... -
A dynamic model of a shell-and-tube condenser operating in a vapour compression refrigeration plant
Elsevier (2008)This work presents a mathematical model of a shell-and-tube condenser based on mass continuity, energy conservation and heat transfer physical fundamentals, whose methodology can be easily adapted for modelling any type ... -
Análisis del ciclo de vida del reciclado del polietileno de alta densidad
Reed Business Information (2008-05)Thermoplastics make up roughly 80% of the plastics produced today. There are hundreds of types of them and new variations are being developed. But not all thermoplastics are recyclable in the same proportion. The most ... -
Environmental risk index: A tool to assess the safety of dams for leachate
Elsevier (2009)Dams for leachate store very toxic substances that contain a large amount of organic material and, probably, heavy metals; they therefore constitute an important threat to the environment. Existing models of environmental ... -
Drift-flux model in a sub-channel of rod bundle geometry
Elsevier (2009)In view of the practical interest of the drift-flux model for two-phase flow analysis, the distribution parameter and drift velocity constitutive equations have been obtained for subcooled boiling flow in a sub-channel of ... -
Influence of material and diameter of pre-fabricated posts on maxillary central incisors restored with crown
Wiley (2009)Numerous research works have studied the effect of post-design parameters on the mechanical behaviour of restored teeth without reaching any clear conclusions. Previous works by the authors ascertained the effect of material ... -
Safety factor nomograms for homogeneous earth dams less than ten meters high
Elsevier (2009)Homogeneous earth dams that are waterproofed with geomembranes are a suitable option for storing water and other sorts of liquids, like leachates from landfills. Such dams do not require complicated engineering technical ... -
Life cycle assessment of composite materials made of recycled thermoplastics combined with rice husks and cotton linters
Springer-Verlag (2009)The goal of this study is to analyze the environmental impact of new composite materials obtained from the combination of recycled thermoplastics (polypropylene [PP] and high-density polyethylene [HDPE]) and biodegradable ... -
