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 ...
Fiber beam model for fire response simulation of axially loaded concrete filled tubular columns
(Elsevier, 2013)
This paper presents a fiber beam model for the fire response simulation of concrete filled tubular columns of circular section under concentric axial load. The model consists of two parallel components, one with a circular ...
Experimental analysis of the internal heat exchanger influence on a vapour compression system performance working with R1234yf as a drop-in replacement for R134a
(Elsevier, 2013-09-25)
This paper presents an experimental analysis of the influence of an internal heat exchanger on the performance of a vapour compression system using R1234yf as a drop-in replacement for R134a. In this work, we compare the ...
Assessing the social performance of municipal solid waste management systems in developing countries: Proposal of indicators and a case study
(Elsevier, 2019-03)
This article analyses the social performance of municipal solid waste (MSW) management systems in developing countries. For this purpose, a set of social impact categories, indicators and metrics capable of assessing the ...
A holistic review of applied methodologies for assessing and selecting the optimal technological alternative from a sustainability perspective
(Elsevier, 2014-02)
Assessing and selecting the optimal technological alternatives in industrial sector is a fundamental tool to improve and adapt the industrial processes to the European legislation, which encourages the incorporation of new ...
Characterization of Tin/Ethylene Glycol Solar Nanofluids Synthesized by Femtosecond Laser Radiation
(John Wiley & Sons, Ltd., 2016-11-22)
Solar energy is available over wide geographical areas and its harnessing is becoming an essential tool to satisfy the ever-increasing demand for energy with minimal environmental impact. Solar nanofluids are a novel solar ...
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 ...
Design and optimization of a semi‐industrial cavitation device for a pretreatment of an anaerobic digestion treatment of excess sludge and pig slurry
(Wiley, 2020)
The use of hydrodynamic cavitation (HC) as a wastewater treatment and anaerobic digestion pretreatment is a well‐known process. However, most of the experiments have been done at laboratory scale and using a low concentration ...
Influence of ultra-high strength infill in slender concrete-filled steel tubular columns
(Elsevier, 2013-07)
This paper describes 24 tests conducted on slender circular tubular columns filled with normal, high, and ultra-high strength concrete for plain, bar reinforced and steel fiber reinforced columns. These were reinforced and ...
Local flow regime analysis in vertical co-current downward two-phase flow
(Elsevier, 2013)
In this work, both global and local flow regimes in two-phase downward flow in a 50.8 mm internal diameter pipe in adiabatic conditions have been identified. The bubble chord length distributions measured simultaneously ...
