Towards a better water resources management and control using bioelectrochemical systems
(English) Freshwater is an extremely scarce yet essential resource for all life forms on planet Earth. Its quality directly impacts the development of human societies as well as the ecosystems balance and health. However, ...
3D FEM meso-level analysis of sulphate attack in concrete: new results and developments using parallel HP computing
(English) When concrete is subject to an environment characterised by a high humidity index and rich in sulphate ions, a concrete degradation process may be initiated due to External Sulphate Attack (ESA). The sulphate ...
Seagrass meadow: a coastal protection perspective
(English) Over the decades, the global coastlines have been a key indicator of the development of actual societies. However, the cost of this growth has resulted in the depredation of natural environments. The increased ...
Aplicabilidad de la ceniza volcánica de baja actividad como nuevo recurso para materiales cementicios sostenibles
(English) Volcanic ash (VA), abundantly available in various regions globally, serves as an effective supplementary cementitious material (SCM) for partially substituting Portland cement (OPC). However, its inherently low ...
Development of a unified fatigue constitutive model: from high to low cycle regime
(English) n a context in which research lines such as optimised design, smart design, use of new materials, weight reduction, etc. are becoming more and more common in the engineering field, techniques that allow for an ...
Numerical approximation of thin structures using stabilized mixed formulations for infinitesimal and finite strain theories, including fluid-structure interaction problem applications
(English) The theories of thin structures can be classified into two main branches depending upon whether shear deformation in the transverse direction is taken into consideration or not. In this context, theories accounting ...
THM numerical modeling of multiphase flow in fractured rock masses using zero-thickness interface elements
(English) To address the impacts of climate change, several measures have been suggested among which utilizing renewable energy sources such as geothermal energy and implementing technologies such as hydrogen storage or ...
Social sciences and humanities in civil engineering: a mixed methods analysis in the context of education
(English) The challenges that the world is currently facing call for solutions that are interdisciplinary in nature. This implies that engineering professionals need to work together with professionals from different ...
Elementos junta/interfase mortar con nudos no coincidentes. Aplicación al análisis de discontinuidades y contactos en geomecánica
(English) The general objectives of this thesis are, on the one hand, to extend the formulation of the traditional zero-thickness interface elements in small deformations to the case of non-coincident meshes and, on the ...
Ecosystem modelling for the ocean decade - facing the challenge
(English) The worlds’marine ecosystems are degrading under wide ranges of ever intensifying, diversifying and co-occurring human pressures. Ecosystem-based management (EBM) approaches have emerged as an alternative to ...
New timber - steel construction system for improved lateral resistance buildings
(Català) A la tecnologia proposada, els elements de fusta s'estableixen de qualsevol manera tradicional o innovadora (per exemple, entramat lleuger o pesat, CLT) i els elements d'acer s'instal·len com a exoestructura. ...
Effective ventilation solutions for educational environments: balancing health, comfort, and sustainability in a post-pandemic scenario
(English) Indoor air quality (IAQ) and thermal comfort are critical in educational buildings, as poor conditions have been linked to reduced cognitive performance, higher absenteeism and long-term health effects. The ...
Modelo de priorización de inversiones de soluciones tecnológicas en smart buildings con criterios de desarrollo sostenible
(English) This Doctoral Thesis addresses aspects of interest for designers, promoters, owners, and managers of office buildings, with the intention of providing clarity on the Smart Building paradigm, as well as identifying ...
Constitutive models for unsaturated soils. A thermodynamic approach
(English) Unsaturated soils are particular instances of porous materials, which are characterized by a solid skeleton and a number of fluids that can move through the skeleton. At the microscale, a porous material is made ...
Modeling of the mixed form of wave problems with correcting terms based on training artificial neural networks: application to acoustic black holes
(English) This thesis presents novel approaches and computational methods for solving wave propagation problems in acoustics and linear elasticity. Stabilized finite element methods in the context of the variational ...
Eliminación de blanqueadores ópticos de aguas textiles residuales y reutilización de efluentes
(English) he textile industry consumes a large volume of water in various activities and is an importan! wastewater generator. Colorless dyes that emit fluorescence when exposed to UV light are used in the optical whitening ...
Análisis estructural de escaleras para edificios frente a viento y sismo
(English) In this PhD Dissertation the structural performance of buildings with stairs submitted to lateral loads, is investigated. Because of the historical neglect of the interaction effects between the main structure ...
Optimization of the bioplastics production from cyanobacteria
(English) Polyhydroxybutyrate (PHB) is one of the most interesting alternatives to conventional plastics, because it has similar properties to polypropylene, it is more biodegradable than other bioplastics, it has really ...
Modeling of emerging organic contaminants during artificial aquifer recharge, transport, degradation and risk associated
(English) Managed Aquifer Recharge (MAR) is a key strategy to increase freshwater resources in many regions facing water scarcity. The success of a MAR facility implies both technical (water quality and quantity as main ...
Methodologies for improving groundwater access in rural areas: towards the improvement of human development in low and middle-income countries
(English) Sustainable groundwater management in rural areas presents multifaceted challenges stemming from hydrogeological complexities, socio-economic disparities, and governance issues. This thesis aims to provide ...
