The use of externally bonded fibre reinforced polymers, FRP, for strengthening reinforced concrete (RC) beams or columns is an alternative to other traditional strengthening techniques due to its high strength-to-weight ...
This thesis develops a new structural strengthening technique: converting existing reinforced concrete structures to composite sections by inserting connectors after controlled demolition with high-pressure water. The key ...
Según estudios estadísticos a nivel mundial, una de las principales causas de fallos en puentes corresponde a problemas relacionados con la interacción entre estructura e hidráulica produciendo altos costos humanos y ...
The post-war industrialized housing between 1955 and 1985 in Belgrade has been analyzed with its special focus on the transformation capacity on spatial, technical and environmental leveL for future refurbishment. The focal ...
In Spain the housing refurbishment hasn’t reached the 25% respect new construction, even though more than the half of the house has been built before 1980. Besides, the construction environmental impact is one of the highest ...
One of the central problems in computer vision is the automatic recognition of object classes. In particular, the detection of the class of human faces is a problem that generates special interest due to the large number ...
In this thesis, we exploit the hierarchical information associated with images to tackle two fundamental problems of computer vision: video object segmentation and video segmentation. In the first part of the thesis, we ...
El impacto de la contaminación del aire es un tema crítico para el medioambiente y el clima. Una mala calidad del aire es un tema de importancia para la salud pública, especialmente en ambientes urbanos. El material ...
This work consists of two parts, both related with regression analysis for interval censored data. Interval censored data x have the property that their value cannot be observed exactly but only the respective interval ...
El análisis de supervivencia trata de la evaluación estadística de variables que miden el tiempo transcurrido hasta un evento de interés. Una particularidad que ha de considerar el análisis de supervivencia son datos ...
La regulación de la actividad de la distribución, aspecto sobre el cual versa esta tesis, ha presentado un horizonte cambiante en los últimos años. Tales cambios se hallan relacionados con aspectos como:<br/>Retribución ...
The deployment delays for EUVL, forces IC design to continue using 193nm wavelength lithography with innovative and costly techniques in order to faithfully print sub-wavelength features and combat lithography induced ...
The Cerda project defines for the first time Barcelona as a metropolis, providing the territorial incorporation framework to other municipalities for more than 150 years. Oasis and center of a larger metropolitan territory. The ...
By using Reinforcement Learning (RL), an autonomous agent interacting with the environment can learn how to take adequate actions for every situation in order to optimally achieve its own goal. RL provides a general ...
En esta tesis se presenta una alternativa a la formulación clásica de elementos finitos basada en elementos de arista (edge elements) y las ecuaciones de Maxwell curl-curl. Este enfoque alternativo se basa en elementos ...
This paper considers the current status of our planet as well as the particular conditions of the economic crisis in Spain in order to propose an analysis of the efficiency involved in reconditioning the skin of the existing ...
One of the top priorities of European countries is to reduce energy consumption and greenhouse gas (GHG) emissions in the built environment. To reach this goal, urban renewal processes are seen as a core strategy towards ...
o:<br/><br/>La investigación pretende contribuir a profundizar en el conocimiento de las circunstancias en que las organizaciones desarrollan la habilidad de adquirir o explotar conocimiento de fuentes externas, denominada ...
Els organismes vius estan composats d'elements químics, principalment C, H, O, N, P i S. L'estudi d'aquests elements essencials és una eina molt útil que permet moure'ns entre diferents nivells d'organització biològica, ...
(English) Environmental inequality metrics require complex analyses between social, economic and environmental variables at different scales. The current research develops metrics within this framework to determine ...
