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 ...
Viabilidad de la valorización energética de lodos procedentes de distintos tipos de depuradoras
(Reed Business Information, 2009)
This work analyses the energy
balance of digested sludge
from six treatment plants from
different sectors of production.
To this end, in the first place it
was necessary to determine the
humidity in order to ...

(Reed Business Information, 2009)
Type III Environmental Declarations as set
out by standard UNE-ISO 14025 (2007) are a
voluntary instrument that organizations can use
to foster the demand for and supply of systems
that have a lower impact on the ...
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 ...
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 ...
El marco DPSIR en los sectores de transporte y agricultura: necesidad del desarrollo de indicadores de impacto en las categorías de ruido y uso de suelo
(Asociación Española de Dirección e Ingeniería de Proyectos (AEIPRO), 2009)
The use of statistical values or environmental measurement results does not suffice to reflect the environmental impact of the sectors of transport and agriculture. Despite its large incidence upon sustainability, ...
Justificación taxonómica del factor del paisaje en el uso del suelo
(Asociación Española de Dirección e Ingeniería de Proyectos (AEIPRO), 2009)
The land use by human beings is the main direct cause of lots of impact in production systems. The term land use is traditionally used to show a classification of human activities that land surface hold. In the field of ...
Averaging methods of the gap heat transfer coefficients and the loss form coefficients of nuclear reactor cores loaded with different fuel bundles
(Elsevier, 2009)
When performing transient analysis in heterogeneous nuclear reactors loaded with different types of fuel bundles is necessary to model the reactor core by a few representative fuel elements with average properties of a ...
Automated modelling of complex refrigeration cycles through topological structure analysis
(Elsevier, 2009)
We have developed a computational method for analysis of refrigeration cycles. The method is well suited for automated analysis of complex refrigeration systems. The refrigerator is specified through a description of flows ...
Comparison of environmental impacts of building structures with in situ cast floors and with precast concrete floors
(Elsevier, 2009)
In this paper, the environmental impacts of two types of slab systems are studied. The first type, a concrete-based one-way spanning slab, is the most common solution in residential buildings in Spain. The second type, a ...
