In the current thesis, two TWIP steels with different chemical composition were successfully subjected to Severe Plastic Deformation with Equal Channel Angular Pressing (ECAP) at warm temperature (300°C), using a die with ...
Márquez Lobato, Yolanda (Date of defense: 2016-11-18)
Biomaterials based on block segmented copolymers constituted by hard and soft segments have attracted much attention for biomedical applications in the last decades, specifically as absorbable monofilament sutures. ...
Abt, Tobias (Date of defense: 2014-07-11)
The thesis at hand deals with the modification of cyclic butylene terephthalate (CBT) with the aim to improve its final properties. CBT polymerizes in an entropically-driven ring-opening polymerization into polymerized CBT ...
Mahboob, Amir (Date of defense: 2021-11-30)
Creating sustainability and public infrastructure is a fairly recent subject the engineering community has been debating. Introducing new building materials or introducing new structural designs is a strategy for constructing ...
Fraga Rivas, Iria (Date of defense: 2010-02-26)
Differential Scanning Calorimetry (DSC) is one of the most widely used thermal analysis techniques for the study of transitions and relaxation processes in polymers and also in other materials. It measures the heat flow ...
Javadian, Hamedreza (Date of defense: 2020-07-16)
Rare Earth Elements (REEs) are known as the remarkable components in many technologies that are driving the modern world. They are widely used in chemical engineering, permanent magnets, fluorescent lighting, sensors, cell ...
Orrit Prat, Jordi (Date of defense: 2012-03-07)
D’ençà que el polietilè reticulat (XLPE) es va començar a utilitzar com aïllament elèctric per cables de subministrament elèctric, s’han destinat molts esforços a l’estudi de les propietats dielèctriques del polietilè i ...
Keridou, Ina (Date of defense: 2021-04-14)
In the last decades, polymeric biomaterials, due to their advanced physical and mechanical properties, have been used in a vast variety of surgical and pharmaceutical applications. In this thesis, a study on crystallinity, ...
Fernández Sánchez, Pablo Gonzalo (Date of defense: 2021-12-20)
Reinforced concrete members, especially when subjected to concentrated loads, can fail in shear. This is an undesirable and brittle failure mode preventing the structure from deforming and reaching higher load levels. It ...
Botero Vega, Juan Felipe (Date of defense: 2013-06-21)
Network virtualization is recognized as an enabling technology for the future Internet. It aims to overcome the resistance of the current Internet to architectural change and to enable a new business model decoupling the ...
Ruiz Mansilla, Rafael (Date of defense: 1994-10-24)
Se establece la metodología, incluyendo la formulación necesaria, para el diseño térmico de subenfriadores criogénicos n2(i)-n2(i), observando en todo momento criterios de optimización para con los diferentes parámetros y ...
Montoro López, Ma. Eulàlia (Date of defense: 2015-05-12)
The aim of this thesis is to study the hyperinvariant and characteristic subspaces of a matrix, or equivalently, of an endomorphism of a finite dimensional vector space. We restrict ourselves to the case of matrices A with ...
Príncipe, Ricardo Javier (Date of defense: 2008-04-21)
La descripción del flujo de fluidos involucra la solución de las ecuaciones de Navier-Stokes compresible, un problema muy complejo cuya estructura matemática no es del todo comprendida. Por lo tanto, mediante análisis ...
Heredero Esteban, Javier (Date of defense: 2016-01-21)
La figura de Subirana ha ido siempre ligada al trio de Arquitectos que formó con Sert y Torres Clavé dentro del GATCPAC. Su nombre ha quedado ligado a obras tan importantes como el conjunto residencial de la Casa Bloc, al ...
Tomico Plasencia, Oscar (Date of defense: 2007-06-26)
El camp d'Experiència d'Usuari consta d'una àmplia gamma d'aspectes diferents sobre la interacció amb productes o serveis. L'experiència d'usuari difereix del paradigma objectiu basat en el rendiment, centrant-se en un ...
Hamad Mohamed, Khaled M. A. (Date of defense: 2015-12-14)
Experimental study was conducted to analyze the physical flow turbulence and sediment distribution with submerged vane. The objectives behind the investigation were verified and compare results with the Odgaard theory, ...
Blanco Botana, Luis (Date of defense: 2017-07-22)
This dissertation deals with different subset selection problems in wireless communications systems. These type of problems have a combinatorial nature, which makes them computationally intractable for medium and large-scale ...
Ferrer Mallén, Olga (Date of defense: 2015-12-22)
This thesis focused on the feasibility of substituting, partially or totally, drinking water treatment plant (DWTP) conventional pre-treatment by membrane based units, in particular by ultrafiltration (UF). For such purpose, ...
Perujo Buxeda, Núria (Date of defense: 2018-07-12)
Infiltration systems are water treatment technologies where water vertically percolates through porous media while several biogeochemical processes occur. Biofilms are the main responsible for those biogeochemical processes ...
