Abstract:

The use of fibre reinforced concrete (FRC) as a construction material has expanded beyond the traditional applications since the publication of design codes and guidelines. In fact, the industry is demanding FRC with increasing structural responsibilities and, in some cases, with the fibres as the only reinforcement. Despite the remarkable advances in the fibre reinforcement technology and the publication of design guidelines, questions continue to arise regarding the performance, the characterization and the modelling of the material. The definition of the constitutive model of FRC and th

Abstract:

Pervious concrete is a special material with high permeability usually obtained by reducing the amount of fine aggregates in the composition of concrete. The properties of pervious concrete not only depend on its composition but also on the construction methods. The compaction process has a direct influence on the values of permeability and mechanical properties achieved. In fact, depending on the level of compaction applied, the same composition might give a highly pervious or even an almost impervious concrete. The interest of the scientific and technical community about pervious concrete ha

Ubiquitous wireless multimedia communications are becoming a reality. Users will be able to communicate and access information etc. just about anytime, anywhere and will always be connected to the network. Telecommunication operators now consider multimedia services as revenue generators. However, the success of multimedia services in attracting customers also depend on the capability of the network to guarantee Quality of Service (QoS). Hence, the topic of multimedia QoS provisioning constitutes an important research area. The research of multimedia QoS provisioning can be divided into two pa

Abstract:

A series of aluminia and titania promoted, silica- supported chromium (III) acetate catalysts were characterized using X-ray photoelectron spectroscopy (XPS) prior to, and after, activation in oxygen at 780 C. The results indicated that Cr (VI) was formed in each case as a result of the activation process. Increased promoter metal binding energies implied an interaction between the promoter and silica support. It is proposed that there is insertion of aluminium and titanium atoms into the silica network, which leads to formation of surface silicates. A qualitative measure of the metal dispersi

Abstract:

Users require applications to help them obtaining knowledge from the web. However, the specific characteristics of web data make it difficult to create these applications. One possible solution to facilitate this task is to extract information from the web, transform and load it to a Web Warehouse, which provides uniform access methods for automatic processing of the data. Web Warehousing is conceptually similar to Data Warehousing approaches used to integrate relational information from databases. However, the structure of the web is very dynamic and cannot be controlled by the Warehouse desi

Abstract:

Lab-on-a-chip arrangements are ever more frequently used for the miniaturization of chemical and biochemical analysis. In these arrangements, all the manipulations of analyte transport, separation, mixing with reactants and detection are integrated and implemented at the scale of a microchip of several cm in size. This makes possible a dramatic reduction in the required amounts of analytes and reactants, as well as in the time of analysis. Besides that, automation and high-throughput operations (due to parallelization) become much easier than in the conventional "macro-laboratory" environments

Weight reduction is one possibility to reduce fuel consumption and emission of transportation vehicles. Sheet metals are often used in automotive and aerospace applications and therefore the weight reduction achieved by reducing the sheet metals thickness is an important contribution to weight reduction.

To prove a maintained safety for parts with a decreased weight Finite Element (FE) simulations are commonly used. This leads to a high demand on the simulation precision

Therefore, classical models should be extended in order to reproduce more complex features of behaviour linked to the soil structure.

Abstract:

In the past decades, composite materials (which are usually classified into fibre-reinforced composites and particle-reinforced composites, depending on the geometry of the reinforcements) have been widely applied in tissue engineering as implant scaffolds. A lot of work has been done on the bulk mechanical properties of these composites. However, there is lack of nanomechanical characterization of such composites, which is crucial for understanding the cell-material interactions at small scale, and further optimizing the design of scaffold materials to promote the formation of new viable tiss

Abstract:

Cette thèse s’inscrit dans un objectif à long terme de contrôle et de pilotage en temps réel du séchage des produits céramiques. Pour cela, cette étude se décompose en deux volets. Une première partie expérimentale qui porte sur la détermination en temps réel des paramètres de séchage (température de l’échantillon, teneur en eau et variations dimensionnelles par méthode optique). Une seconde partie, quant à elle, consiste à étudier l’évolution des propriétés physiques des matériaux pendant le séchage pour ensuite construire un modèle numérique macroscopique qui utilise ces données expérimental

Abstract:

Dans cette thèse, on présente des outils de modélisation pour étudier des structures à bandes interdites photoniques non-linéaires et des microcavités. Premièrement, une CMT et une BPM non linéaires ont été développées pour prouver la propagation de solitons spatiaux dans une structure périodique composée d'une série de guides droits. Suite à ces résultats théoriques notables, des fonctions actives sont envisagées grâce à ces régimes. Une autre méthode a ensuite été développée pour modéliser en trois dimensions des cavités optiques ayant une symétrie circulaire telles que des microdisques. La

Abstract:

Mestrado em Engenharia Eletrónica e de Telecomunicações<br>Gallium nitride (GaN) high electron mobility transistor (HEMT) technology has been revolutionizing the RF power amplifier (PA) market. Its potential, versus existing technologies, such as Silicon (Si) Laterally-Diffused MOS(LDMOS), is yet to be completely explored. However, the lack of good characterization and modelling of charge carrier trapping related phenomena has been hampering PA designers from extracting this technology’s promised performance. Hence, GaN HEMT trapping has been given a great amount of attention by the sci
