The present thesis work is motivated in the recent developments of wireless access technologies, which have given noticeable changes on both operator and end-user side. From the operator side, the wireless access networks have evolved from 1st generation technologies (1G) up to 3rd generation technologies (3G) during the last three decades. Additionally, 4th generation networks (4G) based in advanced radio technologies are already in development phases. The proliferation of wireless access networks yields opportunities to the end-user, however it can also induce a additional problematic due to the complexity of the network to be operated. Therefore, the end-user has the possibility to choose dynamically which access technology (access network) to connect to, in order to obtain the required service. From the moment the decisions from the users occur in a distributed, non-coordinated and generally opportunistic way, the access to wireless networks process dynamics are in a need to be studied. The present thesis work, analyses the competitive access problem by means of game theory. In particular, non-cooperative game models in which the users tend to maximize their individual utility from the access problem are considered. The thesis work presents the development and implementation of a software instrument capable of simulating game dynamics individualizing equilibria conditions and measuring the transition length to reach such equilibria (convergence time). The second part of the thesis work includes the analysis of different realistic wireless access networks considering different access strategies which are selected by the end-users and different utility function formulations with which the players “play” the game.

Vectoring is a novel technology created to expand the capacity boundaries of Veryhigh- bit-rate DSL 2 (VDSL2) systems. It mitigates the reduction of data rate and reach in VDSL2 systems caused by the crosstalk interference that appears when multiple services share the telephone network’s infrastructure. However, the implementation of vectoring on real systems faces numerous challenges that limit its potential to enhance the data rate and reach of VDSL2 systems. Therefore, evaluating its performance in close-to-real scenarios considering different technological aspects has turned into an interesting field of research that also helps in the development of new and faster technologies. This thesis evaluates quantitatively the performance of vectoring on VDSL2 systems. It proposes the extension and parametrization of performance indicators to compare and measure the impact of six different aspects on vectoring systems: network topology, binder occupancy, background noise, channel estimation errors, complexity constraints, and precoding and canceling schemes. Their evaluation requires numerical results that are obtained through a simulation tool, which is designed and implemented as part of this thesis. The obtained results and the conducted analyses give concluding guidelines for the vectoring technology and can be taken into account by manufactures and service providers for the deployment of real systems. In addition, and as a result of the objective of providing an accurate evaluation that represents well the real systems’ performance, this thesis contributes with the statistical characterization of the Far-end Crosstalk (FEXT) in a 50-pair cable binder commonly used in Germany (DTAG-40) and constructs its stochastic model. The model and the results are verified through real systems measurements, reference documents of the Broadband Forum and existing literature. Thus, the simulation tool and the characterized channel model constitute a contribution for the evaluation of DSL systems that can be used in future works.

One of the effects of the globalisation of our society is that people travel more covering longer distances, live far from their work place and consume goods from all around the world. Therefore, it is no coincidence that the transport of people and goods represents more than 25\% of the energy consumption and is one of the principal sources of pollution worldwide. Several efforts must be done to reduce the oil dependence, the energy consumption and the environmental impact of transport systems. In this perspective, the French Army (DGA) has designed and constructed the Electrical Chain Components Evaluation vehicle (ECCE). It is a mobile laboratory to evaluate under real conditions the electric components of Hybrid Electrical Vehicles (HEVs) that reduce the energy consumption and the pollution emission of conventional vehicles. ECCE permits evaluating different energy sources such as batteries, fuel cells, internal combustion engines, ultracapacitors or flywheels. The ECCE project, nowadays in a second phase\footnote{The first phase of the ECCE project is explained in Chapter 1} is developed in joint cooperation with the FEMTO-ST laboratory of the University of Franche-Comté and two industrial partners, HELION and PANHARD General Defense. It aims to study the implementation, control and energy management of different hybrid sources. As a research developed along the second phase of the ECCE project, the principal objective of this thesis is to design, to implement and to evaluate an energy management supervision system in the ECCE HEV. This thesis proposes an original energy management strategy based on expert knowledge and type-2 fuzzy logic. The design of the fuzzy logic controller is done by using knowledge engineering. This technique allows extracting knowledge from several experts using surveys. The consideration of type-2 fuzzy logic systems enables modelling the uncertainty in the answers of the experts. This thesis presents a second application of type-2 fuzzy logic: the voltage regulation of a DC/DC power converter. The principal motivation for developing this application is that it is easier to implement in laboratory at a relatively low cost and it permits a viability evaluation of type-2 fuzzy logic before an implementation in the ECCE mobile laboratory. This is useful because one of the main challenges of this thesis is to reduce the time to experimentally validate the energy management system. This is required to respect the time schedule constraints and to reduce the costs associated to gather the partners of the project at PANHARD locations in Saint-Germain Laval.

Organic semiconductors are used in many fields of photonics. Displays fabricated using organic light emitting diodes (OLED) can be found in modern smartphones and tablets, whereas organic solar cells (OPV - organic photovoltaics) are emerging with demonstrated efficiencies above 10%. Organic photodetectors (OPD) are another very interesting domain, with ultrathin active layers (order of tens of nanometers) providing performance comparable to bulk inorganic devices. Thanks to a multitude of possible compounds, parameters such as response spectrum, cut-off wavelength etc. can be easily tuned. Because of very high absorption coefficient and low refractive index, issues such as crosstalk or reflection can be minimized. Another exciting feature is the low processing temperature and thus feasibility of using a flexible foil as substrate, leading to rollable or curved photodetector arrays.The performance of organic based photodetectors has grown considerably in the recent years in terms of high speed, high frequency response and detectivity so as to match the required custom specifications for practical applications such as imaging. However, further attention needs to go towards the understanding of the effects of scaling during miniaturization of these devices, while looking for the preservation and/or optimization of their opto-electrical properties. Therefore, in this thesis, emphasis is given on the photodetectors based on organic conjugated polymer materials for imaging applications. These organic photodetector devices normally suffer from a perimeter-to-area dark current density scaling, hence, special attention is on the understanding of this scaling effect as well as optimization of the fabrication process in order to get low leakage (dark) current, and therefore, large dynamic range of the OPDs. Photodetectors with different geometries and sizes from 0.08 cm2 down to 1.95E ?5 cm2 were fabricated, using two types of edge cover layer. Isolated islands of two different organic films were patterned with photolithography in order to study the dark current mechanisms. Electrical, optical and morphological properties were characterized for both patterned and non-patterned devices. The patterning process used to fabricate the isolated devices does not affect the optoelectrical and morphological characteristics of the photodetectors, and therefore their performance. Moreover, it does not induce or accelerate degradation of the organic films. The dark current density further decreases after full patterning is performed, while preserving all device characteristics. It is proposed to replace the semitransparent edge cover layer by the opaque, if thicker films can be achieved, as it might be possible to decrease the contribution of the perimeter leakage. Once the patterning process is performed, it is possible to implement these isolated devices as photodetectors arrays for imaging applications with an Ion/Ioff ratio of 6 orders of magnitude. It is proposed to perform a theoretical study of the dark current mechanism at the interface between the polymer and the metallic contact edges to model and simulate the perimeter recombination at reverse bias conditions. Moreover, further measurements such as electroluminescent and spectroscopy might aid to characterize the carrier transport in the OPDs. The project was aimed within the R&D department of large area electronics. Moreover, all the fabrication and characterization were performed in the facilities of IMEC.

Waste management is one of the growing problems in many highly populated cities around the world, and the amount of strategies designed to solve it has changed during the last decade. It passed from land filing to incineration and mechanical biotechnology; this quick change was partially induced by the threat that garbage is for the environment, and later on by the acceleration of climate change, since the public services industry was bound to comply with the emissions reduction targets. The newest technologies are being applied in Europe and North America, giving them a new way to face their waste issues. However, the industrialized States are not the only ones with these concerns, in the developing countries, it is a matter that is becoming an structural problem, because of the population growth and the dynamics of the capitalist practice; moreover, it is difficult to solve due to low budget or lack of knowledge on the topic. In Bogotá D.C, waste management became one of the most controversial topics due to the many problems presented during the implementation of the Zero-Waste program and the past administrative issues with the Landfill Doña Juana that led to many health and land predicaments for the population. As a consequence, this dissertation seeks to create a new strategy to fix the gaps of the original policy, by designing five time-limited specific objectives, a reform to the segregation strategy and proposing the construction Anaerobic Digestion plant as the best solution for the sustainable control of bio-waste. Therefore, this work will show throughout all the chapters the background of the waste management system, the new strategies to be taken into account by the local administration, the advantages of the AD technology and the possible financing channels for the renovation of the Basuras- Cero Policy. All the information above will be use to conclude, that for the case of Bogotá D.C, the use of bio-waste as a new energy source will strengthen the recycling industry (with the establishment of a better segregation system and the construction of and AD plant) reduce the amount of waste sent to Landfill and decrease GHG emissions; and even though it is a small step, it can become the foundation for fixing some weaknesses of the economic system and some social mores.

The sum of small and big decisions made in all levels of companies determines its performance. Also, the quality of the decisions can be improved when there is information available to help decision makers in their task. All this has motivated the development of specific types of information systems aimed to provide the information necessary in the different levels of the company to support structured and semi-structured decision making. This research will be focused on a specific group of information systems to support decisions that make intensive use of historic data integrated from multiple sources; Data-driven Decision Support Systems (DDSS). On the other hand the features of the systems to support decisions together with tasks and techniques that are unique for these systems demanded the creation of specific development methodologies to perform the development process. In response to that demand, several proposals have been elaborated but there is no consensus in the field. Currently there is a debate around two development methodologies that are analysed on this paper. After the analysis of the proposed methodologies a case study organization with experience on the development of DDSS will be analysed. The research aims to understand and present the development process carried out in the organization to develop DDSS. In the analysis the influence of the existing methodologies and other sources, like traditional development methodologies and standardization is included. Finally a proposal to improve the development of DDSS in the case study organization is presented. The proposal is generated in the light of the existing methodologies and other particular proposals that deal with single tasks on the development process.

In this thesis two different studies are presented separately because each study has a different purpose even though the two studies are complementary. For the first study an available dataset for BCI is used. This dataset is consistent with the aim of the first study because it allows the implementation and development of the proposed technique for BCI based on imaginary limb movement with a small amount of electrodes. The technique I implemented trough this study is a reliable option to be used for a BCI-based on imaginary movements. In the second study a different dataset is used because the requirements for the technique to be implemented are different. Training and testing dataset are necessary to describe a practical computational technique that is applied for a single trial classification based on a Common Spatial Pattern and complemented with a linear discriminator. The training data is used to build a classifier and the testing data allows measuring the performance of the classifier implemented. After testing the classifier the good performance obtained makes this technique of great interest for any imaginary movement based-BCI.
