A multi-relational and interactive model for supporting the design process in the conceptual phase
(Elsevier, 2010)
The article presents an interactive model that increases the possibilities of exploration during the design process, increasing the number of ways to guide and build the design alternatives. The model considers a knowledge ...
Transverse vibrations in existing railway bridges under resonant conditions: Single-track versus double-track configurations
(Elsevier, 2010)
In this paper, the dynamic performance of a certain kind of existing bridge under the action of high-speed railway traffic is addressed. Short-to-medium-span simply supported structures are susceptible to experiencing ...
Comparison of different collection systems for sorted household waste in Spain
(Elsevier, 2010)
The purpose of this study was to identify the different selective collection systems implemented in Spanish cities and to analyse the efficiency and extent to which the targets proposed by current law are met in each case. ...
Environmental assessment of alternative municipal solid waste management strategies. A Spanish case study
(Elsevier, 2010)
The aim of this study is to compare, from an environmental point of view, different alternatives for the management of municipal solid waste generated in the town of Castellón de la Plana (Spain). This town currently ...
Numerical simulation of gas-liquid flows in a centrifugal rotor
(Elsevier, 2020-08-10)
Two-phase flows generally represent an adverse condition for centrifugal pumps. Research about this topic tends to be focused on performance evaluation through experimental approaches, while numerical works are quite scarce. ...
Thermoeconomic analysis of CO2 Ejector-Expansion Refrigeration Cycle (EERC) for low-temperature refrigeration in warm climates
(Elsevier, 2021-04)
Refrigeration industry is adopting a proactive strategy to phase out fluorinated greenhouse gases by more sustainable working fluids. R744 is a natural refrigerant widely proposed for commercial refrigeration. Its use in ...
Life cycle assessment of construction and demolition waste management systems: a Spanish case study
(Springer-Verlag, 2012-02)
The aim of this study is to develop and analyse a life cycle inventory of construction and demolition waste (C&DW) management systems based on primary data collected directly from Spanish enterprises involved in the life ...
Thermodynamic analysis of the optimal operating conditions for a two-stage CO2 refrigeration unit in warm climates with and without ejector
(Elsevier, 2021-02-25)
The natural refrigerant R744 seems to be the long term solution to be imposed in the food retail industry, where low and medium refrigeration temperatures are usually required, despite the technical difficulties related ...
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 ...
Free vibrations of simply-supported beam bridges under moving loads: Maximum resonance, cancellation and resonant vertical acceleration
(Elsevier, 2013)
The advent of high-speed railways has raised many concerns regarding the behaviour of bridges. Particularly, the analysis of the free vibrations generated by each load is of great interest because they can possibly accumulate ...
