One of the possible ways to address the constantly increasing amount of heterogeneous and variable internet traffic is the evolution of the current optical networks towards a more flexible, open, and disaggregated paradigm. ...
This dissertation is an experimental research project into the mechanical effects of the ultrasonic vibration-assisted ball burnishing process on the surface integrity of surfaces machined through ball-end milling. Due to ...
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 ...
3D food printing is a precise digitalized process that is based on monitoring the characteristics of the printed substrate in accordance with the process parameters. In this thesis mashed potatoes were first mixed with ...
In the current economical context, the use of waste material with economic potential should be a priority. In this sense, the increasing production of electrical and electronic equipment waste (WEEE) makes these materials ...
En aquest treball tractem tres metodologies diferents -no paramètrica, paramètrica i semiparamètrica- per tal de considerar els patrons de dades amb valors no observats en un context d'anàlisi de la supervivència. Les dues ...
Nowadays biopolymers are a good alternative to petrochemical polymers. One of these biopolymers is Poly[(R)-3- Hydroxybutyrate] (PHB) which is produced from renewable resources by various microorganisms and, after its use ...
Compton cameras are used for radiological imaging, which can be useful in environmental applications and especially in determining the position of hidden sources. Current Compton cameras are based on pixelated detectors ...
Textile wastewater often shows high color concentration, containing a large range of organic chemicals, with high chemical oxygen demand as well as hard-degradation materials. Therefore, understanding and developing effective ...
Cotxes, camions, tractors, avions... tots necessiten els neumàtics com a component imprescindible per al seu funcionament. Malauradament, degut al desgast per ús, els neumàtics tenen una vida útil limitada que obliga a ...
In this thesis, different theoretical approaches designed to study a wide interval of length- and/or time-scales have been used to examine the microscopic properties of chemical systems with varying degrees of complexity ...
Structure is fundamental in shaping the types of computations that neuronal circuits can perform. Explaining the laws that determine the connectivity properties of brain networks and their implications in neuronal dynamics ...
La present tesi es basa en l'estudi dels processos de bioremediació com a tecnologies de descontaminació d'aqüífers.<br/>Concretament, es pretén estudiar la desnitrificació i la decloració reductiva com a tecnologies de ...
Alzheimer's disease (AD) is a neurodegenerative disorder that constitutes the most common dementia pathology. It represents a global epidemic that expands exponentially as the life expectancy increases with no yet useful ...
La patata es una fuente de carbohidratos, de versátil preparación y presentación. Dependiendo del proceso de cocción y de las características morfológicas y nutricionales de la patata estos efectos pueden ser positivos o ...
The magnetically confined plasmas study is one of the most promising research fields in the present days due to the high perspectives of unlimited and clean energy that fusion has generated. In this framework, the stellarator ...
A cell is a the basic structural and functional unit of every living thing, it is protein-based an that regulates itself. The cell eats to stay alive, it grows and develops; reacting to the environment, while subjected to ...
Graphene is the first of the 2D-material family. It is formed by carbon atoms arranged in a honeycomb lattice, which confers it intriguing physical properties that are still being discovered nowadays. A fundamental advantage ...
(English) The most common composite materials for strengthening building structures are divided into two dif ferent types based on the matrix’s composition, organics (polymers) or inorganics (cement, lime). The hybrid ...
The hydro-mechanical behaviour of soils during freezing and thawing is a coupled multi-physics process that has important practical applications. To cite but a few examples, on artificial ground freezing –to provide ...
