Factors determining waste generation in Spanish towns and cities
Springer Verlag (2014-12-10)This paper analyzes the generation and composition of municipal solid waste in Spanish towns and cities with more than 5000 inhabitants, which altogether account for 87 % of the Spanish population. To do so, the total ... -
Fast simulation of railway bridge dynamics accounting for soil–structure interaction
Springer (2021)A novel numerical methodology is presented to solve the dynamic response of railway bridges under the passage of running trains, considering soil–structure interaction. It is advantageous compared to alternative approaches ... -
Fatigue Analysis of NiTi Rotary Endodontic Files through Finite Element Simulation: Effect of Root Canal Geometry on Fatigue Life
MDPI (2021-12-03)This article describes a numerical procedure for estimating the fatigue life of NiTi endodontic rotary files. An enhanced finite element model reproducing the interaction of the endodontic file rotating inside the root ... -
Fatty acid eutectic mixtures and derivatives from non-edible animal fat as phase change materials
Royal Society of Chemistry (2017)A set of compounds from non-edible fat waste was prepared and their thermal behavior was studied. The fat was hydrolyzed and crystallized in a simple and robust process to yield palmitic acid–stearic acid (PA–SA) mixtures. ... -
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 ... -
Finite element formulation to study thermal stresses in nanoencapsulated phase change materials for energy storage
Taylor & Francis (2020-03-09)Nanoencapsulated phase change materials (nePCMs) – which are composed of a core with a phase change material and of a shell that envelopes the core – are currently under research for heat storage applications. Mechanically, ... -
Fire design method for concrete filled tubular columns based on equivalent concrete core cross-section
Elsevier (2015)In this work, a method for a realistic cross-sectional temperature prediction and a simplified fire design method for circular concrete filled tubular columns under axial load are presented. The generalized lack of simple ... -
Fire design of slim‐floor beams
Ernst & Sohn (2019)Slim‐floor beams are a well‐known and cost‐effective solution that permits a significant reduction of floor thickness, and are increasingly used in industrial and commercial buildings. Since only their lower flange is ... -
Flash infrared annealing as a cost-effective and low environmental impact processing method for planar perovskite solar cells
Elsevier (2019)For successful commercialization of perovskite solar cells, straightforward solutions in terms of environmental impact and economic feasibility are still required. Flash Infrared Annealing (FIRA) is a rapid method to ... -
Flat plate solar collector performance using alumina nanofluids: Experimental characterization and efficiency tests
Public Library of Science (2019)Solar energy has become an important renewable energy source for reducing the use of fossil fuels and to mitigate global warming, for which solar collectors constitute a technology that is to be promoted. The use of ... -
Flow regime development analysis in adiabatic upward two-phase flow in a vertical annulus
Elsevier (2011)In this work radial and axial flow regime development in adiabatic upward air–water two-phase flow in a vertical annulus has been investigated. Local flow regimes have been identified using conductivity probes and neural ... -
