Durada dels símptomes i supervivència en el càncer simptomàtic del tub digestiu
Sólo una minoría de estudios sobre la demora diagnostica en el cáncer del tubo digestivo han analizado su influencia sobre la supervivencia, y los que lo han hecho muestran resultados discrepantes: una demora mayor se ha ...
Duration-Based Measures as an Alternative to Studying Union Formation and Fertility
Aquesta tesi té com a objectiu oferir una perspectiva alternativa a l’estudi de la demografia familiar mesurant la durada dels esdeveniments d’unió i fecunditat i desenvolupar tres nous índexs per a una millor comprensió ...
DVFS power management in HPC systems
Recent increase in performance of High Performance Computing (HPC) systems has been followed by even higher increase in power consumption. Power draw of modern supercomputers leads to very high operating costs and ...
Dynamic adaptation of user profiles in recommender systems
In a period of time in which the content available through the Internet increases exponentially and is more easily accessible every day, techniques for aiding the selection and extraction of important and personalised ...
Dynamic assessment of structural building components.
The development of methods that correlate the measure of dynamic parameters with the condition of the structure has received a considerable attention from the engineering community in the last few years. In the field of ...
Dynamic behavior of type IV collagen at cell-biomaterial interface
The initial molecular events that take place at biomaterials interface mimic to a certain extent the natural interaction of cells with the extracellular matrix (ECM). In this thesis we describe the fate of adsorbed type ...
Dynamic computer-assisted surgery for the placement of dental implants
[eng] INTRODUCTION: Computer-Assisted Surgery (CAIS) in Dentistry has been designed with the purpose of minimizing discrepancies between preoperative planning and the final position of the implant. Dynamic CAIS (dCAIS), ...
Dynamic Covalent Capsules based on Calix[4]pyrrole Scaffolds
Aquesta tesi descriu l'assemblatge de caixes i càpsules moleculars basades en enllaços imina que tenen cavitats amb interiors polars. Investiguem l'autoassemblatge dinàmic assistit per una molècula que serveix de “plantilla” ...
