A Computational Approach to the Synthesis of Chiral Sulfoxides
La síntesi de sulfòxids quirals ha estat investigada teòricament considerant dos dels mètodes més avançats: l'oxidació asimètrica de sulfurs amb peròxid d'hidrogen catalitzada per vanadi i el mètode DAG. El mecanisme ...
A computational micromechanics investigation of longitudinal strength in unidirectional fibre reinforced composites
The use of Fibre Reinforced Polymers (FRP) composites has grown in popularity over the last few decades. They offer outstanding mechanical properties combined with a low density, making them an excellent solution for many ...
A Computational Model for the Construction of Knowledge-based Collaborative Learning Distributed Applications
en català:<br/><br/>Un camp de recerca important dins del paradigma del Computer-Supported Collaborative Learning (CSCL) és la importància en la gestió eficaç de la informació d'esdeveniments generada durant l'activitat ...
A computational model of eye guidance, searching for text in real scene images
La cerca d’objectes de text en imatges d’escena reals és un problema obert i una àrea de cerca molt activa la visió per computador. S’han proposat un gran nombre de mètodes basats en l’extensió dels mètodes des de l’anàlisi ...
A computational re-assessment of sexual dimorphism in the human cranium beyond traditional morphometrics: geometric morphometric methods and neural network analysis
L'objectiu principal d'aquesta tesi de doctorat és avançar en l'estudi i la comprensió del dimorfisme sexual en els cranis humans moderns. Per aconseguir aquests objectius, primerament explorem quines són les característiques ...
A computational study of intervertebral disc degeneration in relation to changes in regional tissue composition and disc nutrition
Up to 85% of the world population suffers from low back pain, a clinical condition often related to the intervertebral disc (IVD) degeneration (DD). Altered disc cell nutrition affects cell viability and can generate ...
A Computational toolkit to boost precision oncology with pharmacogenomics
Durant la darrera dècada la seqüenciació massiva de pacients de cancer ha permés avançar de forma significativa el coneixement sobre les bases moleculars del càncer. Un cop assolit aquest primer pass, el repte que tenim ...
A confidence framework for the assessment of optical flow performance
L’Optical Flow (OF) és l’input d’una gran varietat de Sistemes de Suport a Decisions (DSS) com ara assistència a la conducció, guia UAV o diagnosis mèdic. En aquestes situacions, l’absència de ground truth ens obliga a ...
A connective ethnography of a file sharing practice: The bulgarian case
Esta tesis llamada "Etnografía conectada de una práctica de intercambio de archivos: El caso búlgaro", tiene como objetivo proporcionar una comprensión acerca de las actividades de intercambio de archivos, teniendo en ...

A contribution of budding yeast to unravel aging. Entry into quiescence relies on the transceptor Mtl1 by sensing nutrients and regulation of signaling pathways
Saccharomyces cerevisiae is a premier model system to study ageing in post mitotic cells. In this study, we show that Mtl1, member of the Cell Wall Integrity pathway (CWI), plays a positive role in Chronological Life ...
A contribution to chemical process operation support: new machine learning and surrogate models based approaches for process optimization, supervision and control
In the chemical process industry, the decision-making hierarchy is inherently model-based. The scale and complexity of the considered models (e.g., enterprise, plant or unit model) depend on the decision-making level (e.g., ...
