(English) New research shows that global demand for alloys with unique properties for various applications increased drastically, and among all them the demand for high entropy and metallic glasses in the industry is ...
El treball realitzat en aquesta tesi està emmarcat en la missió SMOS (Soil Moisture and Ocean Salinity) de l'Agència Espacial Europea. El satèl·lit es llançarà al febrer del 2007, i mesurarà la salinitat superficial del ...
The Future Circular Hadron Collider (FCC-hh) is a proposal for a 100 km long hadron collider conceived as the successor of the Large Hadron Collider (LHC). The FCC-hh is designed to reach 50 TeV of beam energy, greatly ...
(English) The mechanical characterization of new materials used in the Material Extrusion technique (MEX) in 3D printing is essential. The use of this technique is growing and with it the possible applications of printed ...
The future of hydropower is tied to the rapid increase of new renewable energies, such as photovoltaic and wind energy. With the growing share of intermittent electricity production, the operation of hydropower installations ...
Cured epoxy resins are highly cross-linked polymers which are increasingly important in high performance engineering field due to the stiffness, high strength, heat resistance and solvent resistance. However one major ...
(English) This PhD mostly focuses in studding the flow around a square cylinder with an upstream splitter plate and considering different velocity ratios between the upper and lower inlet velocities. The PhD is based in ...
Aerobiology is the science that focuses on the study of the airborne living organisms (bacteria, fungal spores, pollen, small insects, etc.). The influence of meteorology and climate change on plant phenology include shifts ...
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 ...
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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
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 ...
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 ...
