Programming model abstractions for optimizing I/O intensive applications
This thesis contributes from the perspective of task-based programming models to the efforts of optimizing I/O intensive applications. Throughout this thesis, we propose programming model abstractions and mechanisms that ...
Structural damage monitoring based on machine learning and bio-inspired computing
For a few decades, systems for supervising structures have become increasingly irnportant. In origin, the strategies had as a goal only the detection of damages. Furthermore, now monitoring the civil or military structures ...
Investigación sobre la aceptación de los usuarios de los sistemas electrónicos de gestión de recursos humanos (e-HRM) en una empresa del sector de la automoción
This research investigates factors that impact the use of digital systems for HR management at SEAT, a car manufacturing firm of the Volkswagen Group. Electronic Human Resource Management (e-HRM) is not a completely new ...
HPC memory systems: Implications of system simulation and checkpointing
The memory system is a significant contributor for most of the current challenges in computer architecture: application performance bottlenecks and operational costs in large data-centers as HPC supercomputers. With the ...
Model order reduction of coupled thermo-hydro-mechanical processes in geo-environmental applications
In a large number of geo-environmental applications, it is essential to model coupled processes that depend on several design parameters such as material properties and geometrical features. Thermo-hydro-mechanical (THM) ...
Modelling thermo-mechanical response of metal canister disposed in engineered barrier systems
The main objective of this thesis is to describe and implement a rate-dependent (viscoplastic) constitutive equations for copper based canister using a single internal state variable and use it for modelling disposal schemes ...
Direct numerical simulation of multi-phase flow in complex media
In numerous applications, two-phase liquid-gas transport at sub-millimeter length scales plays a substantial role in the determination of the behavior of the system at hand. As its main application, the present work focuses ...
El espacio a partir del plano: el neoplasticismo en la arquitectura contemporánea
The Dutch De Stijl group was born at a time of common interest among avant-garde artists and architects of the first half of the 20th century in the purification of the means of expression, based until then on a tradition ...
Connectivity sharing for wireless mesh networks
Internet access is still unavailable to one-third of the world population due to the lack of infrastructure, high cost, and the digital divide. Many access-limited communities opt for shared Internet access where they build ...
Assessing the socio-economic impacts of flash floods for early warning at regional, national, and continental scales
Flash floods are one of the most devastating natural hazards, claiming numerous lives and tremendous economic losses. One of the main reasons for their catastrophic potential is the limited time available for precautionary ...
Improvement of down-aisle stability and ductility for unbraced adjustable pallet racking systems
Pallet racking systems are structures intended to store products. Their proper structural design is of paramount importance as its collapse can lead to significant economic losses and even human. This type of structures ...
Calcium phosphate cements and foams: characterization of porosity and use as local drug delivery devices
The topic of this Philosophy Doctor Thesis tallies with the national project MAT2012 of the BBT group of UPC: "Pore4Bone: Biomimetic calcium phosphates: tailoring porosity from the nano- to the macroscale for osteoinduction, ...
Diseño e implementación de un laboratorio destinado a la validación clinica de ayudas para la percepción y movilidad en pacientes con limitación de campo periférico
People with peripheral visual field loss perceive limited information about the environment and present severe problems in achieving successful orientation and mobility. In recent years, virtual and augmented reality systems ...
Modeling and identification of power electronic converters
Nowadays, many industries are moving towards more electrical systems and components. This is done with the purpose of enhancing the efficiency of their systems while being environmentally friendlier and sustainable. ...
Heterotopía en Foucault y su utilidad en el análisis de la arquitectura posmoderna: la singularidad generalizada
This thesis looks at the original notion of heterotopia, followed by its interpretations and applications of different authors and disciplines. The course that takes this notion -from the strange to the generalised-, becomes ...
A new computational approach to topology optimization in solid mechanics problems
This doctoral thesis addresses topology optimization problems at a single scale. Based on this purpose, a new topology optimization approach is developed in order to improve existing and widespread techniques in the research ...
Environmental and occupational characterisation of coals and dust from coal mining
The main objective of this PhD thesis is the study of coal mine dust patterns produced by different types of mining operations and different types of coal. In addition, the potential links between oxidative potential (OP) ...
Exploration and discovery of sponge assemblages on the continental shelf and slope of the Catalano-Balearic Sea by means of non-invasive techniques
Sponge assemblages dominate several distinctive, hard-bottom environments, being one of the most important structural organisms at several locations around the world. Although the Mediterranean sponge fauna is among the ...
Innovation of the process-equipment system in a context of sustainability
In search to contribute to the current fight against climate change, the industrial sector is immersed in a transition to the Circular Economy (CE) to achieve resource efficiency through the redesign of products and ...
Mejora de la eficiencia en la compensación de agujas náuticas
The objective of this thesis is to improve the efficiency in the compass adjustment. First, a complete, orderly, synthetic and updated study on this matter is performed, including the state of the art, as well as the ...
