Research on fluidic oscillators under incompressible and compressible flow conditions
One of the main advantages of fluidic oscillators is that they do not have moving parts, which brings high reliability whenever being used in real applications. To use these devices in real applications, it is necessary ...
Study and characterization of mechanical properties of wood-PLA composite (Timberfill) material parts built through fused filament fabrication
This research is based upon the additive manufacturing (AM) technology which aims to study the mechanical properties of innovative commercial wood-PLA composite material (Timberfill) and characterize its behavior. Specifically ...
Mathematical formulations of water mixing for reactive transport through heterogeneous media
The study of transport of reacting solute through aquifers is relevant in many engineering fields. Reactive transport (RT) is complex because it consists of two phenomena, solute transport and chemical reactions, both of ...
Exploring quantum many-body systems from an entanglement and nonlocality perspective
Entanglement and non-local correlations give rise to unprecedented phenomena with no classical analogue. As a result, they have settled themselves as fundamental properties in the study of quantum many-body systems, as ...
Innovative mathematical and numerical models for studying the deformation of shells during industrial forming processes with the Finite Element Method
The doctoral thesis "Innovative mathematical and numerical models for studying the deformation of shells during industrial forming processes with the Finite Element Method" aims to contribute to the development of finite ...
Balance de masa e identificación de indicadores para medir eficiencia en la gestión y procesado de materiales en las plantas públicas de compostaje de Fracción Orgánica de Residuos Municipales (FORM) de Cataluña
The importance for the good management of the waste increases day by day, due to the increase of the generation of waste .Composting is one of the most used treatments in the management of the organic fraction of municipal ...
Diffusion processes and nanoparticle growth
Es conocido que muchas propiedades de las nanopartículas, como la luminiscencia, la fotoestabilidad, la eficiencia de la radiación óptica y las propiedades eléctricas, dependen del tamaño. Por lo tanto, la capacidad de ...
Contributions to the energy management of industrial refrigeration systems: a data-driven perspective
Nowadays, energy management has gained attention due to the constant increment of energy consumption in industry and the pollution problems that this fact supposes. On this subject, one of the main industrial sectors, the ...
Estudio del mecanizado asistido por vibración
The objective of this work is to analyze the influence of assisted vibration, VAM, in the process of turning steel. Initially, the surface finish generated in a lathe displacement is studied utilizing a geometric intersection ...
Edge computing infrastructure for 5G networks: a placement optimization solution
This thesis focuses on how to optimize the placement of the Edge Computing infrastructure for upcoming 5G networks. To this aim, the core contributions of this research are twofold: 1) a novel heuristic called Hybrid ...
Arquitectura, ciencia-ficción y comic-books : vanguardias, evolución y lenguaje
Esta tesis propone como elemento de investigación al trinomio formado por la Arquitectura, la Ciencia-ficción y los Comic-books. La intención es multidisciplinar; investigando las relaciones existentes y evidenciado las ...
Encuentros con la infraestructura :Intersecciones entre infraestructuras lineales elevadas y arquitecturas de la ciudad sedimentada europea
This thesis investigates the encounters between elevated linear infrastructures and architectures of the European sedimentary city. The scalar contraposition between these two opposing urban elements (one small-grained ...
Flexural fatigue of pre-cracked fibre reinforced concrete: experimental study and numerical modelling
Fibre reinforced concrete (FRC) is recognized as suitable material for structural applications. The number of national codes that have approved it is an evidence. Structures where FRC is generally used can be subjected to ...
Hybrid non-destructive technique for volumetric defect analysis and reconstruction by remote laser induced ultrasound
This PhD thesis is devoted to the design, development and implementation of a non-contact hybrid non-destructive testing (NDT) method applied to the analysis of metallic objects that contain embedded defects or fractures. ...
Spatial modulation schemes and modem architectures for millimeter wave radio systems
The rapid growth of wireless industry opens the door to several use cases such as internet of things and device-to-device communications, which require boosting the reliability and the spectral efficiency of the wireless ...
Suelo rural metropolitano : estudios, planes y proyectos en tres regiones del Sur de Europa
This research deals with rural land treatment in the urban planning of three metropolitan regions of southern Europe from the beginning of the twentieth century to the present day, focusing on how it has contributed to ...
Resource optimization in SDN-based inter/intra data centre networks
Upon the demanding requirements brought by next-generation services, current network infrastructures are required to evolve in the way they manage different types of resources at the data layer. To this end, a set of novel ...
Manejo integrado de plagas en legumbres almacenadas mediante el uso de atmósferas modificadas y de control biológico
Spain is one of the main producing countries of chickpeas and beans in Europe and is also the main importer. Nowadays, pest control is mainly based on the application of phosphine. However, the risks on human health and ...
Optimization of interplanetari trajectories with gravity assist
Interplanetary travel is a difficult task due to the high fuel mass required to reach other planets. Minimizing the cost of the manoeuvres (and, in turn, the fuel mass) is the objective preliminary mission design. During ...
Multiapproach computational modelling of tuberculosis : understanding its epidemiological dynamics for improving its control in Nigeria
Tuberculosis (TB) is an infectious disease that is considered to be the biggest killer of mankind in the history of infectious diseases. There are still more than 10 million new TB cases every year and it causes more than ...
