Improved dynamical particle swarm optimization method for structural dynamics
(2019-06)
Article
Open AccessA methodology to the multiobjective structural design of buildings based on an improved particle swarm optimization algorithm is presented, which has proved to be very efficient and robust in nonlinear problems and when ... -
Co-digestion strategies to enhance microalgae anaerobic digestion: a review
(2019-09)
Article
Restricted access - publisher's policyMicroalgae biorefineries for the production of biofuels and high-value products have captured the attention of academia and industry. Implementing an anaerobic digestion step can enhance resource recovery from microalgae ... -
High-cycle fatigue constitutive model and a load-advance strategy for the analysis of unidirectional fiber reinforced composites subjected to longitudinal loads
(2019-07)
Article
Restricted access - publisher's policyA fatigue constitutive model valid for the composite constituent will be presented in this paper. The composite behaviour will be obtained by means of the serial/parallel mixing theory that is also used as a constitutive ... -
An Exploratory Multivariate Statistical Analysis to Assess Urban Diversity
(2019-07-11)
Article
Open AccessUnderstanding diversity in complex urban systems is fundamental in facing current and future sustainability challenges. In this article, we apply an exploratory multivariate statistical analysis (i.e., Principal Component ... -
Variational approach to relaxed topological optimization: closed form solutions for structural problems in a sequential pseudo-time framework
(2019-10)
Article
Restricted access - publisher's policyThe work explores a specific scenario for structural computational optimization based on the following elements: (a) a relaxed optimization setting considering the ersatz (bi-material) approximation, (b) a treatment based ... -
Modelling flood propagation in the service galleries of a nuclear power plant
(2019-10)
Article
Restricted access - publisher's policyIn the context of the stress tests that have to be applied to nuclear power plants, this work presents the study of the flooding processes of the service galleries of a nuclear plant caused by a hypothetical failure of ... -
Swelling behaviour of compacted Maryland clay under different boundary conditions
(Thomas Telford, 2019-06)
Article
Restricted access - publisher's policyThis paper presents an experimental study on the swelling response of compacted Maryland clay specimens subjected to hydration under a range of boundary conditions. The research is multi-scale with swelling tests complemented ... -
Monitoring and modelling instream wood in rivers
(2019-01)
Article
Restricted access - publisher's policyDuring the past three years the WoodFlow project (2015-2019), funded by the Federal Office for the Environment) aimed to develop the knowledge and methods to analyse instream large wood dynamics and to mitigate potential ... -
Early Pliocene climatic optimum, cooling and early glaciation deduced by terrestrial and marine environmental changes in SW Spain
(2019-09)
Article
Restricted access - publisher's policyThe Pliocene is a key period in Earth's climate evolution, as it records the transition from warm and stable conditions to the colder and more variable glaciated climate of the Pleistocene. Simultaneously, climate became ... -
Swimming Euglena respond to confinement with a behavioural change enabling effective crawling
(2019-02-18)
Article
Restricted access - publisher's policySome euglenids, a family of aquatic unicellular organisms, can develop highly concerted, large-amplitude peristaltic body deformations. This remarkable behaviour has been known for centuries. Yet, its function remains ... -
A statistical forecasting model applied to container throughput in a multi-port gateway system: the Barcelona-Tarragona-Valencia case
(2019-04)
Article
Restricted access - publisher's policyThis contribution investigates the container throughput flow in a multi-port gateway system: Barcelona-Tarragona-Valencia (BTV). First, the paper examine the recent dynamics of the total and transshipment flow showing a ... -
Effects of pre-wetting aggregate on the properties of mortars made with recycled concrete and lightweight aggregates
(2019-06)
Article
Open AccessThis paper examines the suitability of partially replacing natural aggregate, sand, (NA) with recycled concrete aggregate (RCA) or lightweight aggregate (LWA) in mortars, under the hypothesis that pre-wetting aggregates ...
