The development of synthetic bone substitutes with enhanced osteogenic properties is urged by the global ageing population. Sintered calcium-phosphate (CaP) ceramics are the most widely used synthetic biomaterials for bone ...
Quantum mechanics was developed as a response to the inadequacy of classical physics in explaining certain physical phenomena. While it has proved immensely successful, it also presents several features that severely ...
The frequency of occurrence of an accident is a key aspect in the risk assessment field. Variables such as the human factor, which is a major cause of undesired events in process industries, are usually not considered ...
Aquesta tesi està dedicada a l'estudi de la utilització de informació morfosintàctica en el marc dels sistemes de traducció estocàstica, amb l'objectiu de millorar-ne la qualitat a través de la incorporació de informació ...
As distributed electronic systems grow to include thousands of components, from grid to peer-to-peer nodes, from (Semantic) Web services to web-apps to computation in the cloud, governance of such systems is becoming a ...
Nowadays, Information and Communication Technologies and Internet play an important role supporting everyday objectives. The speed of tasks performance, the easy access to all kind of information and the possibility of ...
In this research work, an analysis is first undertaken on the hazard regarding people exposed to floods in urban areas. Several experiments with people were carried out in order to determine the stability limit to pedestrians, ...
La estimación del esfuerzo respiratorio durante el sueño es de una importancia crítica para la identificación correcta de eventos respiratorios en los trastornos respiratorios del sueño (TRS), el diagnóstico correcto de ...
Context: Probabilistic selling is the strategy that the seller creates an additional probabilistic product using existing products. The exact information is unknown to customers until they receive the probabilistic products. ...
Given an elliptic curve E over the complex numbers (CC) given by y^2 = x^3 + ax + b, there exists a lattice L in CC such that the group E(CC) of complex points on E is isomorphic to the complex analytic group CC/L. This ...
Wildfires are an ecological phenomenon inherent to earth dynamics and widely spread over the globe. In addition to the environmental impact, when wildfires grow beyond controllable magnitudes, they pose a principal threat ...
En esta tesis se realiza el análisis y la síntesis de inversores bidireccionales con aislamiento en alta frecuencia. Entre las aplicaciones que se contemplan podemos destacar: sistemas de alimentación fotovoltaicos, sistemas ...
This thesis presents a characterization of the charge structures of thunderstorms and lightning leader development, and their relationship with the emissions of terrestrial gamma ray flashes (TGFs). The results include a ...
(English) Getting to give added value in the different products that are nowadays in the market has not been easy. Since many years ago we have worked on the addition of fragrances in different articles. This added value ...
This research investigates factors that impact the use of digital systems for HR management at SEAT, a car manufacturing firm of the Volkswagen Group. Electronic Human Resource Management (e-HRM) is not a completely new ...
(English) Total Compensation is currently understood as the set of elements, not exclusively financial, that employees receive as compensation for their work. In this sense, it can be a decisive factor in attracting and ...
(English) We perform quantum simulation on classical and quantum computers and set up a machine learning framework in which we can map out phase diagrams of known and unknown quantum many-body systems in an unsupervised ...
The techniques for detection of the atmosphere constituents and their distribution in the space have evolved in the last years driven by needs in the environmental, meteorological and climate science fields and backed by ...
Esta investigación está conducida a la resolución del problema de encontrar soluciones rentables para el despliegue de redes de fibra hasta el hogar (Fibre to the Home - FTTH). En una red de FTTH, el equipo transmisor-receptor ...
In this PhD it has been analyzed the antioxidant activity of five plants: Camelia sinensis, Gentian lutea, Betula pendula, Convolvulus arvensis and Arctostaphylos uva-ursi. An Electronic Paramagnetic Resonance has been ...
