(1, ≤ ℓ)-identifying codes in digraphs and graphs
The main subject of this PhD thesis is the study of (1,=l)-identifying codes in digraphs. The results presented in this work are divided into three parts. The first one focusses on the structural properties of digraphs ...
222Rn as a tracer for air mass transport characterization at 100-m-high tower in the south-west Spanish coast
Es los últimos años se han llevado a cabo importantes trabajos de investigación, tomando el gas radón como elemento de evaluación en modelos de transporte atmosférico y así estimar el flujo de partículas. Además la utilización ...
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 ...
3D mapping and path planning from range data
This thesis reports research on mapping, terrain classification and path planning. These are classical problems in robotics, typically studied independently, and here we link such problems by framing them within a common ...
3D Partial scans models for people recognition with a RGB-D sensor
Research developed in this thesis is motivated by a vision of a future where social activities and personalized services are delivered in intelligent environments, entering a new era of more natural and wholesome human-machine ...
3D pose estimation in complex environments
Although there has been remarkable progress in the pose estimation literature, there are still a number of limitations when existing algorithms must be applied in everyday applications, especially in uncontrolled environments. ...
3D printing of aluminum alloys under different extrusion techniques
(English) This doctoral research evaluated the feasibility of using various aluminum-based feedstocks in additive manufacturing (AM) to develop cost-effective and environmentally friendly alternatives to traditional metal ...
3D printing of zirconia-based ceramic materials
(English) Zirconia stands out among oxide ceramics for its superior mechanical properties. This approach resulted from the significant research that has been conducted since the discovery of the tbughening capabilities of ...
3D simulation of magneto-mechanical coupling in MRI scanners using high order FEM and POD
Magnetic Resonance Imaging (MRI) scanners have become an essential tool in the medical industry due to their ability to produce high resolution images of the human body. To generate an image of the body, MRI scanners combine ...
3D-printed biomimetic bone
(English) Over 2 million bone grafting procedures are performed each year. In the last years, synthetic calcium phosphates have drawn the attention of the researchers for their close similarity to the mineral phase of bone ...
3D-printed biomimetic bone grafts: clinical validation and improvement strategies
(English) Bone defects pose a major clinical and socio-economic burden and there is a clear need for new bone grafting strategies that take into account the physical-chemical properties of the native bone, to help treat ...
3D-printed polymeric bioresorbable stents for cardiovascular applications
(English) Bioresorbable stents (BRS) have been envisioned as a revolution in the treatment of coronary heart disease. Ideally, stents would initially retain sufficient radial strength after implantation to prevent vessel ...
4H-SiC Integrated circuits for high temperature and harsh environment applications
Silicon Carbide (SiC) has received a special attention in the last decades thanks to its superior electrical, mechanical and chemical proprieties. SiC is mostly used for applications where Silicon is limited, becoming a ...
5G and its impact on the automotive industry
(English) The 5th generation of mobile communications has been designed to address the unstoppable demand of data bandwidth. However, it also gives support to a range of vertical industries with different Quality of Service ...
858: la crisis de la solvencia: un modelo económico-financiero para un entorno en transición.
Esta investigación nace del análisis de la economía española, fuertemente anclada en el sector construcción y se centra en la investigación de alternativas para afrontar un cambio de modelo. En efecto, la Sociedad española ...
A Bayesian approach to robust identification: application to fault detection
In the Control Engineering field, the so-called Robust Identification techniques deal with the problem of obtaining not only a nominal model of the plant, but also an estimate of the uncertainty associated to the nominal ...
A bioeconomic analysis of the coastal fishery of Pernambuco State, North-eastern Brazil
Los conceptos bioeconómicos modernos invocan la importancia de definir los derechos de propiedad posibles de ser llevados a cabo dentro del contexto de gestión. La investigación pesquera debe considerar las expectativas ...
A census for curves and surfaces with diophantine stability over finite fields
An algebraic variety defined over a field is said to have Diophantine stability for an extension of this field if the variety does not acquire new points in the extension. Diophantine stability has a growing interest due ...
A Cobertura da Unité d'Habitation de Marselha e a Pergunta de Le Corbusier pelo Lugar Público
La bibliografía existente sobra la Unidad de Habitación de Marsella de Le Corbusier - una de las más importantes propuestas de vivienda colectiva del siglo XX -, se basa esencialmente en el estudio del conjunto de viviendas ...
A code for multiphase reactive transport modeling of concentrated solutions under extreme dry conditions
La modelació del transport reactiu multifàsic (TRMF) involucra la simulació del flux de fases fluïdes, el transport de compostos químics i energia, i les reaccions químiques. La majoria dels codis de transport reactiu ...
