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 ...
Criteria analysis of green public procurement in the Spanish furniture sector
(Elsevier, 2020-02-21)
Green Public Procurement (GPP) constitutes a potential policy instrument to reduce the environmental impact of products, services and works, and to create environmental value for society. Further requirements had to be ...
Upward vertical two-phase flow local flow regime identification using neural network techniques
(Elsevier, 2008)
Traditionally, the flow regimes in two-phase flow are considered in a global sense. However, a local flow regime is required to understand and model the interfacial structures present in the flow. In this work, a new ...
Assessment of the Relationships Among Design Methods, Design Activities, and Creativity
(ASME The American Society of Mechanical Engineers, 2012)
This paper presents an experimental study that was conducted to compare the results obtained from using different design methods (brainstorming (BR), functional analysis (FA), and SCAMPER) in design processes. The objectives ...
A Finite Element Model for Consideration of the Torsional Effect on the Bearing Contact of Gear Drives
(ASME The American Society of Mechanical Engineers, 2012)
The finite element method is widely applied for the determination of contact and bending stresses in gear drives. It is based on the finite element model of the gear drive that is built by the discretization of the pinion ...
Effects of Carbon Nanohorn Based Nanofluids Pool Boiling on Optical Properties and Wettability of Different Metal Surfaces
(Taylor & Francis, 2020-09-16)
Oxidized carbon nanohorn water based nanofluids are attracting more and more attention for solar harvesting applications because of their peculiar features: stable suspension without any surfactant, higher solar absorbance ...
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 ...
Application of a lumped model for predicting energy performance of a variable-speed vapour compression system
(Elsevier, 2010)
This work presents a model for a variable-speed vapour compression system that is able to predict accurately the system performance using data easily obtained from an industrial facility. The model uses information on the ...
Environmental performance of ceramic tiles: Improvement proposals
(Elsevier, 2010)
Ceramic tile is one of the most widely used materials in construction. Due to the increased demand for environmentally responsible construction and the ever more restrictive environmental requirements derived from the ...
