Structural behaviour of masonry arches on moving supports : from on-site observation to experimental and numerical analysis
Since ancient times, master builders have used arches to cover large spans in masonry structures. As a consequence, nowadays the safety assessment of these structural elements plays a fundamental role in the conservation ...
Ejecución de túneles en terreno deltaico mediante tuneladora EPB : el caso de la línea 9
The urban tunneling may generate significant problems. One of the main concerns is the unavoidable ground movements generated; before, during and after the tunneling operations. In this context, the objective of this Thesis ...
Performance of distributed optical fiber sensors embedded inside reinforced concrete structural elements.
The employment of a novel cutting edge strain monitoring technique named Distributed Optical Fiber Sensors (DOFS) as Structural Health Monitoring (SHM) tools is becoming increasingly common. Its popularity can be attributed ...
High rate algal ponds for post-treating sewage from UASB reactors : treatment efficiency, anaerobic co-digestion and sustainability
This PhD thesis aimed at evaluating the performance of high rate algal ponds (HRAP) to post-treat the anaerobic effluent from an upflow anaerobic sludge blanket (UASB) reactor fed with sewage. The work analysed the system ...
Study of a hybrid system : Moving Bed Biofilm Reactor-Membrane Bioreactor (MBBR-MBR) in the treatment and reuse of textile industrial effluents
Textile wastewater often shows high color concentration, containing a large range of organic chemicals, with high chemical oxygen demand as well as hard-degradation materials. Therefore, understanding and developing effective ...
Multirate mass transfer and biofilm growth modeling in porous media
Reactive transport modeling is a methodological tool to study the coupled physical, chemical and biological processes in Earth system. It is complex not only because of the nature of the equations, but also because of the ...
Long-term impact of an editorial intervention to improve paper transparency and reproducibility
This PhD thesis is concerned with evaluating the long-term effects of interventions in the editorial peer review process of a biomedical journal. The growing need to increase the value of research and avoid waste motivates ...
