El estudio del comportamiento mecánico-resistente de la obra de fábrica, como material de construcción, empleado en diversidad de edificaciones tanto de carácter histórico como actual, ha sido materia de interés relativamente ...
Esta tesis analiza las relaciones entre el pensamiento urbanístico y los debates paisajísticos en São Paulo en la primera mitad del siglo XX, enfocando como los planes urbanísticos para la ciudad incorporaron los parques ...
The most common decisions to be taken in the design of logistic systems are related to the location of facilities and the management of vehicle fleets.<br><br/>In this thesis, we study three of the optimization problems ...
Les dades composicionals són vectors les components dels quals representen proporcions respecte d'un total, i per tant estan sotmesos a la restricció que la suma de les seves components és una constant. L'espai natural per ...
This Doctoral Thesis addresses aspects of interest for hydraulic infrastructure managers, such as investment decision support tools, in order to provide both decision support and the justification tools which are required ...
La tesis se inscribe en un doble ámbito científico formado por la Estadística y la Pedagogía. El objetivo de la tesis es la investigación de modelos estadísticos y estrategias de análisis que puedan ser de utilidad en el ...
The present thesis deals with the foundations for solving the decision problem of site selection for a feasibility study of gas-fired power plants, based on realistic and practical statements, under a business approach. ...
The study of stellar winds (SW) in the context of X-ray bursts (XRB) performed in this thesis has two main motivating issues. The first is whether or not the heavy elements produced from nucleosynthesis in XRBs can escape ...
This thesis investigates how school building architecture was developed according to modern principles between 1956 and 1968 in the Mediterranean area (Barcelona and Valencia) as a response to the relationship between form, ...
La tècnica (el seu poder transformador, però també la fascinació que produeix) és al centre dels debats culturals de principis de segle XX, també als de l'arquitectura. Així, en el cas català, dins del programa cultural ...
The notion of the Islamic city evoked in comparison with European cities and their modernization process and often criticized for its Eurocentric nature, acknowledges the characteristics’ existence that are shared by ...
Polymers are becoming preferred materials in biomedical applications because of their vast diversity of properties, functionalities and applications. Properties as mechanical strength, stability against degradation, ...
The purpose of this PhD thesis was to investigate the sensitivity of the rheological, thermal, mechanical and fracture behaviours on the topological changes induced in two commercial PLA grades. PLA 2002D and PLA 4032D ...
Development of polymeric biomaterials with tailored properties is essential for expanding biotechnologies and, therefore, proposing novel solutions for diagnostic and treatments in modern medicine. In order to contribute ...
