A satisfiability modulo theories approach to constraint programming
In this thesis we focus on solving CSPs using SMT. Essentially, what we do is reformulating CSPs into SMT. The obtained results allow us to conclude that state-of-the-art SMT solvers are a robust tool to solve CSPs. We ...
Adaptive urban modelling for solar energy simulations
In summary, this thesis proposes to address the problem of simulating physical effects in large urban environments through the use of procedural rules and Level-of-Detail techniques, in order to reduce the computational ...
Advanced techniques in trajectory data analysis for anomaly detection and map construction
With a large amount of trajectory data generated every day, there is a high demand for developing advanced techniques to discover the underlying information instead of dull and heavy manual work. This thesis focuses on the ...
Aportacions de l'anàlisi composicional a les mixtures de distribucions
The present thesis is a compendium of three original works produced between 2014 and 2018. The papers have a common link: they are different contributions made by compositional data analysis to the study of the models based ...
Augmented film narrative by use on non-photorealistic rendering: from 3D cinema to virtual reality
It is stated that non-photorealistic rendering (NPR) triggers specific ocular behaviors that can have a real effect on the way of perceiving a cinematic narrative. The transdisciplinary interest of this thesis lies in ...
Avenços en els fonaments matemàtics de l’anàlisi composicional de dades: convexitat i normes Lp. Aplicació a la regressió lineal LASSO amb covariable composicional
ENG- Compositional data are a special type of multivariate data where the variables represent parts of a whole. These data are commonly encountered in fields such as geology, biology, economics, and chemistry, where the ...
Compositional methodology and statistical inference of family relationships using genetic markers
The present thesis is a compendium of three research articles produced between 2015 and 2019. The three articles are different contributions based on compositional statistical methodology and statistical inference of ...
Continuity and interpolation techniques for computer graphics
In Computer Graphics applications, it is a common practice to texture 3D models to apply material properties to them. Then, once the models are textured, they are deformed to create new poses that can be more appropriate ...
GPU parallel algorithms for reporting movement behaviour patterns in spatiotemporal databases
In this thesis we treat and solve various problems related to movement pattern detection by designing and implementing parallel algorithms using the GPU. We first propose a GPU pipeline based algorithm to report the ’Popular ...
Gràfic de control T2 de Hotelling per a dades composicionals
Compositional data are defined as vectors of components that represent parts of a whole and contain relative information (e.g. %, ppm, mg/l...). CoDa are widely found in chemical, pharmaceutical and food industries among ...
High dynamic range content acquisition from multiple exposures
The limited dynamic range of digital images can be extended by composing different exposures of the same scene to produce HDR images. This thesis is composed of an overview of the state of the art techniques and three ...
Imaginación visual: nuevo paradigma en interfaces cerebro-máquina
This doctoral thesis focuses on the study of the use of visual imagery for the construction of brain-computer interfaces (BCI) non-invasive. Although the construction of brain-computer interfaces is already is a reality, ...
Medical imaging applied to teaching and meat science
Medical imaging has greatly progressed to become an essential technology in current clinical processes. However, advances in diagnostic imaging have not been applied to the same extent to other fields such as education and ...
Medical imaging techniques for the analysis and measurement of composite materials
The purpose of this thesis is the research and development of methods, algorithms and tools for the analysis of composite materials. In order to improve their properties, one must employ specific techniques in order to ...
Methods for remote stock monitoring using depth sensors
RGB-D cameras return images like an ordinary camera but in addition to color, depthmaps where each pixel value represents the distance to a point of the scene are also obtained. Although originally conceived for gaming and ...
Multimodal visualization based on mutual information
Medical imaging and 3D volumetric visualization are a standard routine for patient diagnosis and treatment. Multimodal visualization plays an important role in medical diagnosis and treatment, because it makes findings ...
New solutions to control robotic environments: quality control in food packaging
Machine vision systems and artificial intelligence techniques are two active research areas in the context of Industry 4.0. Their combination allows the reproduction of human procedures while improving the performance ...
Noves tecnologies i aplicacions innovadores per l'ensenyament d'assignatures d’empresa en estudis d’enginyeria
The present doctoral thesis explores an e-learning proposal fruit of using Information and Communication Technologies (ICT) with the objective of improving students’ learning experience. The proposal aims to facilitate the ...
Parallel spatial data structures for interactive rendering
The main question explored in this thesis is how to define novel parallel random-access data structures for surface and image spatial data with efficient construction, storage, and query memory access patterns. Our main ...
Perceptual information-theoretic measures for viewpoint selection and object recognition
Viewpoint selection has been an emerging area in computer graphics for some years, and it is now getting maturity with applications in fields such as scene navigation, volume visualization, object recognition, mesh ...
