Programming models to support data science workflows
Data Science workflows have become a must to progress in many scientific areas such as life, health, and earth sciences. In contrast to traditional HPC workflows, they are more heterogeneous; combining binary executions, ...
(1, ≤ ℓ)-identifying codes in digraphs and graphs
The main subject of this PhD thesis is the study of (1,=l)-identifying codes in digraphs. The results presented in this work are divided into three parts. The first one focusses on the structural properties of digraphs ...
Exploring free-energy landscapes and microscopic interactions of selected small-molecules and proteins with cell membranes
The present Thesis is devoted to the study of the physical-chemical properties of selected small-molecules (such as amino-acids like tryptophan or hormones like melatonin) and proteins (such as KRAS-4B) absorbed in model ...
Contributions to bluetooth low energy mesh networks
Bluetooth Low Energy (BLE) has become a popular Internet of Things (IoT) technology. However, it was originally designed to only support the star topology. This PhD thesis investigates and evaluates different Bluetooth Low ...
Spectral phase control of nanoscale nonlinear optical responses
The study of light-driven physical processes generated in nanomaterials require shorter (in time, or broader in frequency) laser pulses with techniques to tailor its phase and temporal/spectral characteristics at the ...
Chemical design and validation of Ca 2+ -releasing platforms to promote vascularization in tissue regeneration
An insufficient vascularization of the wound site is often the cause of failure in tissue regeneration. The use of cell therapy or growth factors has introduced promising results, nevertheless, they are risky, expensive ...
Advances in state estimation, diagnosis and control of complex systems
This dissertation intends to provide theoretical and practical contributions on estimation, diagnosis and control of complex systems, especially in the mathematical form of descriptor systems. The research is motivated by ...
Comportamiento de un suelo compactado bajo un estado generalizado de tensiones
This thesis analyzes the hydro-mechanical behavior under a generalized stress state of a compacted mixture of sand (30%) and clayey (70%) at a low density. The experimental study focuses on the analysis of shear strength ...
Aplicación de la fermentación láctica como estrategia de transformación y valoración de matrices vegetales
In Colombia, strategies are being promoted to increase fruit and vegetable production, in order to take advantage of agricultural potential. However, there are also high food losses, low consumption and low transformation. ...
Hydroxyapatite-based materials for smart antitumor drug delivery systems, endocytic pathways and endosomal trafficking : polymers and biopolymers
Development of new drug molecule is expensive and time consuming. Improving safety efficacy ratio of “old” drugs has been attempted using different methods such as individualizing drug therapy, dose titration, and therapeutic ...
Coastal risk forecast system : fostering proactive management at the Catalan coast
The action of sea storms is one of the most complex littoral processes with deep management implications. Along the Catalan shoreline which is about 700 km long, 190 km are subject to erosion and/or flooding. Around one ...
Learning to extract features for 2D – 3D multimodal registration
The ability to capture depth information form an scene has greatly increased in the recent years. 3D sensors, traditionally high cost and low resolution sensors, are being democratized and 3D scans of indoor and outdoor ...
L’agricultura en els espais metropolitans : el cas de la Regió Metropolitana de Barcelona
Urban agriculture is defined, as the agricultural and livestock activities that are carried out within or around cities. FAO's definition includes those services offered by agrarian activity that benefit the society. In ...
Finite calculus. A stabilized finite element method for solving the Navier-Stokes equations. Application to ocean turbulence
Ocean turbulence is a classic example of turbulent motion and observations of turbulence in the ocean lack in regions of complex topography since in-situ and experimental data are complicated to obtain. As a result, ocean ...
Espacio y memoria : un viaje por las ruinas de la guerra civil española
This doctoral thesis shows the result of research conducted into the history and character of the villages that still lie in ruins in Spain, ultimately as a result of the damage caused during a war that took place between ...
Societal metabolism focused on water management : application of the MuSIASEM tool in Yucatán Península, México
This Ph.D. thesis analyzes the supply and demand of water in the Yucatan Peninsula, México (YP), from the societal metabolism of water perspective. On one hand, an estimation of water supply is made based on a monthly water ...
Contributions to aerostructures morphing with piezoelectric actuators
Since the first models developed in the late 19th century, the applications of piezoelectric materials have been progressively growing in number. The capacity of these materials to couple electric and mechanic fields makes ...
Predicción del alcance de propagación de información e influencia en redes sociales online
Online social networks (OSNs) are increasinglyused by different sectors of societywith the purpose of informing and influencing people. These sectors are: govemments, political parties, non-govemmental organizations, ...
Levitation and control of particles with internal degrees of freedom
Levitodynamics is a fast growing field that studies the levitation and manipulation of micro- and nanoobjects, fuelled by both fundamental physics questions and technological applications. Due to the isolated nature of ...
Imaging cytometry technology for environmental and biomedical applications
Early detection of microorganisms in environmental and biomedical applications is critical for the effective response to potential pathogenic treats. Most traditional methods and instrumentation for the analysis of these ...
