Computational fluid dynamics techniques for fixed-bed biofilm systems modeling : numerical simulations and experimental characterization
(Universitat Politècnica de Catalunya, 2018-12-13)
Tesi
Accés obertThis thesis is focused on the development of one-phase and multiphase models using computational fluid dynamics (CFD) techniques to analyze biosystems behavior at mesoscale. In the first part, the operation of a fixed-bed ... -
Compiler and runtime based parallelization & optimization for GPUs
(Universitat Politècnica de Catalunya, 2018-12-13)
Tesi
Accés obertGraphics Processing Units (GPU) have been widely adopted to accelerate the execution of HPC workloads due to their vast computational throughput, ability to execute a large number of threads inside SIMD groups in parallel ... -
Physics-based motion planning for grasping and manipulation
(Universitat Politècnica de Catalunya, 2018-12-04)
Tesi
Accés obertThis thesis develops a series of knowledge-oriented physics-based motion planning algorithms for grasping and manipulation in cluttered an uncertain environments. The main idea is to use high-level knowledge-based reasoning ... -
Prospects of distributed electricity generation and services based on small scale biomass systems in Ghana
(Universitat Politècnica de Catalunya, 2018-12-03)
Tesi
Accés obertAccess to energy is crucial to human welfare; no residential, commercial or industrial activity can be conceived without energy supply. At the same time, current dependence on fossil fuels and their negative effects on ... -
Sustainability and firm performance : evidence from corportate and farm level
(Universitat Politècnica de Catalunya, 2018-12-04)
Tesi
Accés obertThis thesis approaches the question of sustainability and firm performance. In the contemporary business model, firm performance measurement must take into account not only economic profits, but also environmental and ... -
Aggressive undervolting of FPGAs : power & reliability trade-offs
(Universitat Politècnica de Catalunya, 2018-11-19)
Tesi
Accés obertIn this work, we evaluate aggressive undervolting, i.e., voltage underscaling below the nominal level to reduce the energy consumption of Field Programmable Gate Arrays (FPGAs). Usually, voltage guardbands are added by ... -
Habitar el casco antiguo : el uso residencial como modo de conservación contemporáneo
(Universitat Politècnica de Catalunya, 2018-12-03)
Tesi
Accés obertThe Historic Center in the contemporary city is a place that objectively and subjectively contains a local representation and at the same time it is a global place immersed in a tourist network of historic cities. The ... -
The generative, analytic and instructional capacities of sound in architecture : fundamentals, tools and evaluation of a design methodology
(Universitat Politècnica de Catalunya, 2018-12-04)
Tesi
Accés obertThe disciplines of space and time form two domains to which it is daring to compare, since it is obvious that they are of a different nature. Music happens in time, while architecture happens in space. However, from the ... -
Nutrient recovery from waste water treatment plant by sorption processes : technical and economic analysis
(Universitat Politècnica de Catalunya, 2018-11-29)
Tesi
Accés obertIn the last years has been performed a huge number of research related to nutrients (mainly N and P) recovery from waste water in order to promote their reuse and also to avoid eutrophication. Recovering nutrient from waste ... -
Remobilització dels contaminants orgànics persistents en els ecosistemes polars costaners
(Universitat Politècnica de Catalunya, 2018-11-12)
Tesi
Accés obertPersistent organic pollutants (POPs) constitute an heterogeneous group of chemical substances of great environmental relevance. Its persistence, bioaccumulation, long-range transport potential and negative effects on health ... -
Hardware runtime management for task-based programming models
(Universitat Politècnica de Catalunya, 2018-11-26)
Tesi
Accés obertTask-based programming models allow programmers to express applications as a collection of tasks with dependences. They are simple to use and greatly improve programmability by using software runtimes to exploit task ... -
Syntrophic acetate oxidation in the anaerobic digestion of nitrogen-rich wastes : from microbial interactions to process optimization
(Universitat Politècnica de Catalunya, 2018-11-09)
Tesi
Accés obertThe anaerobic digestion (AD) consists of a cascade of syntrophic interactions between several microbial groups that result in the breakdown of biodegradable organic matter in the absence of oxygen, resulting in the production ...
