[en] Due to worldwide energy consumption increase, different energy strategies are growing in order to reduce fossil fuel consumption, increase renewable energy impact and increase energy efficiency. Renewable energy impact in the electric grid is increased by combination with energy storage systems. Energy storage systems storage energy during low consumption periods and insert energy during high power demand time. The efficiency and the stability of the electric grid are improved. The thesis work is focused on the energy improvement of Li-ion based energy storage systems. To improve the energy of series connected Li-ion energy storage system balancing systems are required. The thesis deals with the analysis of unbalancing processes in series connected Li-ion cells and the balancing system design to improve the Li-ion battery pack energetic behavior. The search of a low complexity active balancing system to compete against the passive balancing system is one of the most important research lines.

[eu] Mundu mailako energia kontsumoa igotzen ari denez, araudi energetiko berriak sortzen ari dira erregai fosilen kontsumoa murritzeko, energia berriztagarriak ezartzeko eta efizientzia energetikoa handitzeko. Energia berriztagarrien ezartzea eta beraien erabilpena sare elektrikoan, asko hobetzen da metatze sistemen laguntzarekin. Metatze sistemek energia batzen dute kontsumo txikiko uneetan energia txertatuz sare elektrikora kontsumo handiko aldiuneetan, sare elektrikoaren efizientzia eta egonkortasuna hobetuz. Tesi lana litio ioizko metatze sistemen energia efizientzia hobetzean datza. Litio ioizko metatze sistemak litio zelden serie konekzioak dira. Seriean konektatuko sistema hauen efizientzia hobetzeko beharrezkoa da sistema orekatzaileak erabiltzea zelden artean sortutako desberdintasunak konpentsatzeko. Tesi hau zelden arteko desoreken analisian eta desoreka hauek konpentsatzeko beharrezkoak diren oreka sistemen diseinuan zentratzen da. Oreka sistema aktibo konpetitiboen diseinua, oreka sistema pasiboekin lehiatzeko da tesiaren lan inguru nagusienetakoa.

[en] Dependable electrical power distribution systems demand high reliability levels that cause increased maintenance costs to the utilities. Often, the extra costs are the result of unnecessary maintenance procedures, which can be avoided by monitoring the equipment and predicting the future system evolution by means of statistical methods (prognostics). The present thesis aims at designing accurate methods for predicting the degradation of high and medium voltage underground Cross-Linked Polyethylene (XLPE) cables within an electrical power distribution grid, and predicting their remaining useful life, in order inform maintenance procedures. However, electric power distribution grids are large, components interact with each other, and they degrade with time and use. Solving the statistics of the predictive models of the power grids currently requires long numerical simulations that demand large computational resources and long simulation times even when using advanced parallel architectures. Often, approximate models are used in order to reduce the simulation time and the required resources. In this context, Field Programmable Gate Arrays (FPGAs) can be employed to accelerate the simulation of these stochastic processes. However, the adaptation of the physicsbased degradation models of underground cables for FPGA simulation can be complex. Accordingly, this thesis proposes an FPGA-based framework for the on-line monitoring and prognosis of underground cables based on an electro-thermal degradation model that is adapted for its accelerated simulation in the programmable logic of an FPGA.

[eu] Energia elektrikoaren banaketa-sare konfidagarriek fidagarritasun maila altuak eskatzen dituzte, eta honek beraien mantenketa kostuen igoera dakar. Kostu hauen arrazoia beraien bizitzan goizegi egiten diren mantenketa prozesuei dagokie askotan, eta hauek eragoztea posible da, ekipamenduaren monitorizazioa eginez eta sistemaren etorkizuneko eboluzioa aurrez estimatuz (prognosia). Tesi honen helburua lurpeko tentsio altu eta ertaineko Cross-Linked Polyethylene (XLPE) kable sistemen eboluzioa eta geratzen zaien bizitza aurreikusiko duten metodo egokiak definitzea izango da, banaketa-sare elektriko baten barruan, ondoren mantenketa prozesu optimo bat ahalbidetuko duena. Hala ere, sistema hauek oso jokaera dinamikoa daukate. Konponente ezberdinek beraien artean elkar eragiten dute eta degradatu egiten dira denboran eta erabileraren ondorioz. Estatistika hauen soluzio analitikoa lortzea ezinezkoa da gaur egun, eta errekurtso asko eskatzen dituen simulazio luzeak behar ditu zenbakizko erantzun bat lortzeko, arkitektura paralelo aurreratuak erabili arren. Field Programmable Gate Array (FPGA)k prozesu estokastiko hauen simulazioa azkartzeko erabil daitezke, baina lurpeko kableen degradazio prozesuen modelo fisikoak FPGA exekuziorako egokitzea konplexua izan daiteke. Beraz, tesi honek FPGA baten logika programagarrian azeleratu ahal izateko egokitua izan den degradazio elektrotermiko modelo baten oinarritutako monitorizazio eta prognosi metodologia bat proposatzen du.

[en] This PhD dissertation analyzes the performance of second generation digital video broadcasting (DVB) systems in mobile terrestrial environments and proposes an iterative detection algorithm based on factor graphs (FG) to reduce the distortion caused by the time variation of the channel, providing error-free communication in very severe mobile conditions. The research work focuses on mobile scenarios where the intercarrier interference (ICI) is very high: high vehicular speeds when long orthogonal frequency-division multiplexing (OFDM) blocks are used. As a starting point, we provide the theoretical background on the main topics behind the transmission and reception of terrestrial digital television signals in mobile environments, along with a general overview of the main signal processing techniques included in last generation terrestrial DVB systems. The proposed FG-based detector design is then assessed over a simpli ed bit-interleaved coded modulation (BICM)-OFDM communication scheme for a wide variety of mobile environments. Extensive simulation results show the e ectiveness of the proposed belief propagation (BP) algorithm over the channels of interest in this research work. Moreover, assuming that low density parity-check (LDPC) codes are decoded by means of FG-based algorithms, a high-order FG is de ned in order to accomplish joint signal detection and decoding into the same FG framework, o ering a fully parallel structure very suitable when long OFDM blocks are employed. Finally, the proposed algorithms are analyzed over the physical layer of DVB-T2 speci cation. Two reception schemes are proposed which exploit the frequency and time-diversity inherent in time-varying channels with the aim of achieving a reasonable trade-o among performance, complexity and latency.

[en] The main objective of this study is to analyze the perception of teachers in the Com-pulsory Secondary Education stage regarding the STEM educational model, due to its influen-ce on the implementation of teaching-learning processes. Therefore, teachers are the main drivers of the implementation of the STEM model, and the practices that will be carried out will depend on their perception around this framework. In order to achieve this objective, 12 teachers of Natural Sciences, Technology and Mathematics of 5 educational centers of all the networks of Gipuzkoa have been interviewed in depth, using a previously designed script. The results show that teachers have a similar vision to the educational field STEM and, above all, they point out the need for time, resources and quality training for the design, implementation and evaluation of STEM projects, as concluded in many previous studies.

[en] Many mechanical components such as, bearing housings, exible couplings and spines or steel wires are simultaneously subjected to fatigue and fretting damage. Fretting phenomenon arises when two bodies are in contact subjected to relative movement of small amplitude, producing damage to the contacting surfaces. Depending on the magnitude of the stresses two types of failure may occur: fretting wear and fretting fatigue. While the former is dominated mainly by wear mechanism, the second is dominated by crack nucleation and its subsequent growth. Both damage mechanisms can cause catastrophic failure of such mechanical devices. In this research work, scientific and technological knowledge on numerical simulation of coupled wear, crack nucleation and propagation due to fretting and fatigue phenomena has been developed. The main results of this scientific research are: Development of a 2D numerical model of coupled fretting wear and fatigue phenomena that combines wear, crack initiation and its subsequent propagation. This numerical model has enabled to increase knowledge on coupled fretting wear and fatigue phenomena and establish criteria for the development of a 3D model. Experimental analysis item of wear and fretting fatigue in small diameter wires that can feed and validate the 3D numerical model. Development of a 3D numerical model for life assessment on coupled fretting wear and fatigue phenomena in thin steel wires. The numerical model has been validated with experimental results obtained with the developed ad-hoc tribometer.

[eu] Osagai mekanikok degradazio fenomeno ezberdinak jasaten dituzte beraien erabilpenean, hauetako garrantzitsuenetariko batzuk nekea eta fretting-a direlarik. Degradazio fenomeno hauek jasaten dituzten osagai mekanikoen artean malgukien akoplamenduak, egituretako artikulazioak edo kable metalikoak aurki daitezke. Kable metalikoetako barneko hari kontaktuen artean sortzen den anplitude txikiko irristadura da fretting fenomenoaren adibide bat. Kontaktu hauen esfortzu magnitudeen arabera, bi degradazio mota ezberdindu daitezke: fretting bidezko higadura eta fretting bidezko nekea. Kable metalikoen kasuan bi fenomeno hauen arteko konbinaketa da garrantzitsua. Higadura honek, tensio kontzentradore bezala jokatu dezake kableek duten neke ahalmena murriztuaz.

[en] The aim of the present paper is to analyse and characterise the way in which teacher educators work with student teachers when conducting analyses of their own practice by means of selfconfrontation interviews. The corpus of this work consists of 10 self-confrontation interviews carried out by 5 teacher educators. The role of those teacher educators was analysed using the transcriptions of the interviews and 9 categories were identified. Two categories were found to be the most common: demanding specifications and creating controversy. Differences were also found as regards teacher educators' profile. As a result, in-depth training for teacher educators has been considered as needed.

[en] In current industrial environments, the software of embedded systems have to cope with the increasing complexity and robustness requirements at runtime. One way to manage these requirements is having the software component's behaviour model available at runtime (models@run.time). In this paper, we present a model-driven approach to generate software components which are able both to provide their internal information in model terms at runtime and adapt their behaviour automatically when an error or an unexpected situation is detected. Thanks to this introspection ability at runtime, the software components are able to adapt automatically from their normal-mode behaviour to a safe-mode behaviour which was defined to be used in erroneous or unexpected situations at runtime.

[en] In the belief that students pursuing a Master's degree in Teacher Training in the Hu-manities and Social Sciences should reflect on society and society's view of teaching, and therefore also keeping in mind that they should consider what the social context of teaching should be, we will try to answer the following three questions: 1) What is the function of social knowledge today? 2) Why and for what purpose do we teach the social sciences? and 3) What content do we wish to transmit? In answering the first two questions, we will think about and reflect on what kind of paradigm we wish to promote in the social sciences, and that will lead us to propose answers to the third question. In any case, before we answer the final question, reflection is needed with those who intend to become teach-ers of knowledge, so that they will be able to consciously explain why and for what purpose they de-cided to promote a given model of the social sciences.
