[en] The automation of industry in general and the use of industrial robots in assembly lines in particular has considerably increased in the last two decades. Although industrial robots have received significant attention from academic research, there is a lack of contributions focused on the predictive maintenance of these complex systems. In the era of the fourth industrial revolution, improvements in industrial sensorization, data analysis and cyber-physical infrastructures, allow to address the predictive maintenance of industrial robots from a data-driven perspective. This research work reports on experimental evidence of reliable data-driven techniques for the predictive maintenance of industrial robots. This thesis presents four main contributions: the diagnosis of the health status of an industrial robot using visionbased techniques, the feasibility of using torque sensors to diagnose the conditions of industrial robots in real industrial environments, the optimization of the standby pose of robots with genetic algorithms and the design and implementation of a practical data acquisition network for real world industrial scenarios, respectively.

[eu] Industria automatizazioak orokorrean eta zehazki muntaketa-kateetan robot industrialen erabilerak gorakada handia izan du azken bi hamarkadetan. Nahiz eta mundu akademikoak sakon jorratu duen robotika, ikerketa hutsune nabaria dago sistema konplexu hauen mantenketaren arloan. Gaur egungo sentsorizazio teknologiek, datuen analisiak eta infraestruktura ziber-fisikoen aurrerakuntzek, ikerketa hutsune hau betetzeko datuen analisian oinarritutako soluzioak proposatzea ahalbidetzen dute. Lan honetan jorratzen den ikerketa robot industrialen mantenketa prediktiboan datza. Horretarako, datuen analisian oinarritutako ikerketaz baliatuz. Tesian zehar hurrengo lau ekarpen nagusi aurkeztuko dira: Robot industrialen osasun egoeraren diagnosia ikusmen teknikak erabiliz, torke sentsoreen erabilgarritasunaren azterketa roboten osasunaren diagnosirako, roboten itxarote posizioaren optimizazioa algoritmo genetikoak erabiliz eta industrian inplementagarria den roboten monitorizaziorako sare arkitektura baten diseinu eta inplementazioa.

[en] This research identifies the wind energy as the main renewable source. In order to improve its LCoE, SiC semiconductors are proposed, together with different voltage levels and topologies. After analyzing various configurations, two that improve current LCoE are found. The first considers current cost of SiC, and uses a two level topology, achieving little improvement. The second considers the expected cost reduction of SiC due to technological maturity, and it is shown that a three level NPC is the best topology, with higher LCoE improvement.

[eu] Ikerketa honetan energia eolikoa energia berriztagarri nagusi bezala identifikatzen da. Beraren LCoEa (Levelized Cost of Energy ingelesez) hobetzeko, SiC erdieroaleak proposatzen dira, baita tentsio maila eta topologia berriak ere. Konfigurazio ezberdinak aztertzen dira, LCoEa hobetzen duten bi aurkituz. Lehenengoak, gaur egungo SiC-en kostua kontuan izanik bi mailako topologia erabiltzen du, hobekuntza txikia lortuz. Bigarrenean, teknologiaren heldutasunagatik iritsiko den kostu jaitsiera aurre ikusten da, eta hiru mailako NPC (Neutral Point Clamped ingelesez) topologia erabiltzea dela onena ikusten da, LCoE hobekuntza handia lortuz.
[en] This bachelor's thesis aims to standardize the production lines of solar panels. The process has been divided into different phases, starting from the programming and simulation of the line, continuing with its actual implementation and fine-tuning, and concluding by documenting the process for future projects. To achieve this goal, the student has been involved in the real project of Meyer Burger, being engaged from the beginning to the end. In order to carry out this work, TwinCAT 3 applications have been used for programming, Visual Components Professional for simulation, iX Developer for the human-machine interface, and Easy Starter for the start-up of the lines. In this context, TwinCAT 3 acts as the central core, connecting and coordinating the functions of the other three applications. The result of this work is documented in this present paper with the purpose of facilitating and providing guidance for future projects.

[en] Transversal cutting processes are usually employed for metal coil cutting or precut reduction operations. The final result of a cutting operation, in terms of sheared edge quality and process forces, is dependent on the process parameters and on the material's behavior. In order to determine the effects of the process parameters, an hydraulic blanking prototype is employed to perform transversal cutting operations on a High Strength Steel plate with 10 mm of thickness. These results will help to understand the force requirements of the process and to meet customers' sheared edge quality requirements.

[en] The Internet has become the backbone of the lives of today's children and teenagers. The advantages of the net are many, but it also has risks. The consequences of some online actions can harm the well-being of children and adolescents. That is why it is important to work on preventive measures for the responsible use of the Internet from an early age. The aim of the #IzanDig project is to raise awareness of the need for these preventive measures and involve all educational agents in this work. This paper analyses the productions made by the 384 students who participated in the project in one of the proposed forums to identify the requests they make and the commitments they assume. They refer mainly to the importance of privacy and require the support and care of adults (family and teachers).

[en] Socioeconomic and cultural changes taking place in the far and near environments have a direct impact on our language and cultural identity. We focused on the use of the Basque language by the new students at MU-HUHEZI, and on their perception of Basque culture, in order to identify the reasons for changes observed in the profiles of these new students. In a four-year project designed for this purpose, the students first read the book EOSKOLA during the 2017-2018 academic year. They then had an interview with the author and completed a questionnaire. The results indicate that the students' language use and cultural perceptions are diverse, and that in order to address this, it is necessary to review both language competence and the curriculum, with greater attention to the Basque dimension.

[eu] Ingurune urruti zein hurbilean gertatzen ari diren aldaketa sozioekonomiko nahiz kulturalek eragin zuzena dute gure hizkuntza- eta kultura-identitatean. MU-HUHEZIra datozen ikasle etorri berrien euskararen erabilerari eta euskal kulturaren pertzepzioari jarri diegu arreta, ikasle berrien profil horietan sumatzen diren aldaketen arrazoiak identifikatzeko. Helburu horrekin diseinatu zen lau urteko proiektuan, ikasleek EOSKOLA liburua irakurri behar izan zuten 2017-2018 ikasturtean; ondoren, elkarrizketa bat izan zuten egilearekin, eta, azkenik, galdetegi bati erantzun behar izan zioten. Egindako lanketatik ateratako emaitzek adierazi digute ikasleen hizkuntza-erabilera zein kultura-pertzepzioa askotarikoak direla, eta horri erantzuteko hizkuntza-konpetentziaren zein curriculumaren berrikuspena egitea —euskal dimentsioari arreta gehiago jarriz— beharrezkoa dela.
[en] Nowadays, students present difficulties in choosing to continue their academic career (Pérez and Aldas, 2019). Therefore, in this study it was wanted to take steps that will help to fill the gap of orientation in the choice of a university degree. Thus, a research has been conducted to identify the skills and interests of students and reconcile them with the skills of the labor branch. Through Artificial Intelligence and Big Data, the final objective of the project is to provide students with additional orientation data in the future and to create personalized itineraries.

[eu] Egungo ikasleek beren ibilbide akademikoan jarraitzeko hautaketan hainbat zailtasun izaten dituzte (Pérez eta Aldas, 2019). Hori dela eta, ikasleen orientazioan laguntza eskaintzea nahi izan da ikerketa honetan, ikaskuntza pertsonalizatuan oinarrituz. Horrela, ikasleen konpetentziak eta interesak identifikatu eta horiek lan-adarreko konpetentziekin uztartzeko ikerketa egin da. Inteligentzia Artifizialaren (IA aurrerantzean) eta Big Dataren bidez, etorkizunean ikasleei orientaziorako datu gehigarriak ematea eta ibilbide pertsonalizatuak sortzea da proiektuaren helburu nagusia.
[en] The series connection of power semiconductor devices allows the operation at voltage levels higher than the levels allowed by one single semiconductor. However, due to individual parameter differences of the series connected devices it is difficult to ensure a proper voltage balance between the series connected power devices and if any semiconductor exceeds its maximum blocking voltage it will fail. Because of its gate controllability and its low gate energy requirements, the IGBT is the preferred choice when high number of switching devices must be connected in series. In this research work an IGBT gate driver has been developed which will control the behaviour of the IGBT during the switching process. In consequence, this gate driver should ensure a proper voltage balance between the series connected IGBT devices. Basically, this PhD research work deals with the analysis and the modelling of the behaviour of the IGBT / Diode, proposes an active gate control and shows its validity for the series connection of IGBT / Diode devices. Finally, voltage source converter topologies are briefly compared for reactive power compensation applications at Medium Voltage utility grids. The required blocking voltage capacity is achieved by means of the series connection of power semiconductor devices.

[eu] Potentzi erdi eroaleen serie elkarketak, erdi eroale batek jasan dezakeena baino tentsio maila altuagoan lan egitea ahalbideratzen du. Hala ere, erdi eroaleen arteko ezaugarri ezberditasunak direla eta, zaila egiten da tentsio banaketa egokia zihurtatzea. Erdi eroaleetariko batek bere gehienezko tentsio maila gainditzen badu honek huts egingo du. Erdi eroale asko seriean elkartu behar direnean IGBT-a izaten da aukerarik hobetsiena bere kontrolagarritasuna eta behar duen ateko energia maila baxua dela eta. Ikerketa lan honetan IGBT baten ateko "driver"-a garatu da. Honek IGBT-aren konmutazio prozesua kontrolatu behar du eta aldi berean, seriean elkarturiko IGBT-en artean, tentsio banaketa egokia lortu. Funtsean, ikerketa lan honetan IGBT eta Diodo-aren analisia eta modelatua erakusten dira. Modu berean "driver"-ean erabilitako kontrola eta bere baliozkotasuna IGBT/Diodo-en serie elkarketarako erakusten dira. Azkenik, Tentsio Ertaineko sarera zuzenean konektaturiko Tentsio Iturri Bihurgailuen arteko konparaketa bat egin da. Sareko tentsio maila altua dela eta erdi eroaleen serie elkarketa derrigorrezkoa da.

[en] This thesis presents the results obtained from the study about the effect of organizational, individual and contextual factors on adaptation and turnover intention of Spanish repatriates. Traditionally, the literature has been focused on investigating the impact of organizational practices on repatriation but recent new studies suggest that this approach is insufficient. According to those, individual and contextual factors are also influencial on repatriation. Thus, a model that combines both perspectives has been developed: on one hand it takes into account the traditional or organizational perspective (which includes organizational and managerial variables) and on the other hand the emergent or proactive perspective (which includes individual and contextual variables). The results support the view of taking both perspectives into consideration. It is confirmed that, in addition to the managerial factors of the organization, there are some other characteristics of the individuals and their context that will also affect their return, which could be very helpful for determining and prioritizing actions when companies manage international assignments. Finally, the research proposes two empirically validated models: one for adaptation upon return and the second one for turnover intention on repatriation. Both describe a series of relationships among the analyzed variables, which as a result, show some guidelines for reaching a complete adaptation and a non turnover intention of the repatriates.

[eu] Tesi honek espainiar langile errepatriatuen egokitzapenean eta enpresatik alde egiteko intentzioan aldagai enpresarialek, pertsonalek eta langilearen ingurunearekin erlazionatutakoek duten eraginaren inguruko ikerketaren emaitzak aurkezten ditu. Tradizionalki literatura langilearen errepatriazioan aldagai enpresarialek duten eraginaren ikerketara bideratu da; baina gaur egungo hainbat ikerketek ikuspegi hau nahikoa ez dela adierazten dute. Hauekin bat, garrantzitsua da aberriratze prozesuan aldagai pertsonalek eta ingurenekoek duten eragina aztertzea. Hau dela eta, bi ikuspegiak konbinatzen dituen eredu bat sortu da: tradizionala edo enpresariala (enpresa kudeaketari lotutako aldagaiak barne hartzen dituena) eta suspertzen ari dena edo proaktiboa (honek, gizabanakoari eta inguruneari lotutako aldagaiak biltzen ditu). 10 Lortutako emaitzek ikuspegi biei ematen diete euskarria. Beraz, hau egiaztatzen da: enpresaren kudeaketaz gain, langilearen itzuleraren emaitzan eragina duten norbanakoaren eta bere ingurunearen baldintzatzaile batzuk ere badaude. Hau oso erabilgarria izan daiteke nazioarteko mugikortasunaren kudeaketaren inguruan enpresek martxan jarri behar dituzten ekintzak erabaki eta lehenesteko. Azkenik, lan honek balioztatutako bi eredu enpiriko proposatzen ditu: lehenengoa, itzuleran ematen den egokitzapena aztertzeko eta bigarrena enpresa usteko asmoa lantzeko. Biek eskaintzen dituzte aztertutako aldagaien arteko erlazioak eta, horien bitartez, langile errepatriatuen egokitzapena eta enpresa usteko asmo eza lortzeko bideak azaltzen dira.
[en] Skin ulcers are a serious threat to public health system, and, although wound healing is a natural process, a proper dressing can improve the healing process. In this work, platelet rich plasma (PRP) coated polycaprolactone (PCL) wound dressings have been designed by means of electrospinning. PCL is a biocompatible and biodegradable synthetic polymer. PRP, in turn, offers growth factors to the dressing, which are significant in the healing. To enable an effective addition of PRP, functionalization of PCL fibre meshes has been carried out by immersing them in alkaline dissolution of different concentrations. In this way, a novel wound dressing that aids in the regeneration of damaged skin layers has been developed.

[en] The present study aims to explore the written production of scientific arguments of Se-condary Education students in Basque, Spanish and English at the discourse and lexicogram-matical levels. Argumentation elements (following Toulmin) were analysed in the texts written by 34 years 9 students, and the employed lexicogrammar was identified through a discourse analysis. Across-language similarities were found both in the use of argumentation elements and in the lexicogrammatical resources employed.

[eu] Ikerketa honen helburua da, Derrigorrezko Bigarren Hezkuntzako (DBH) ikasleek zientziaren eremuan euskaraz, gaztelaniaz eta ingelesez ekoizten dituzten argudioak maila diskurtsibo eta lexiko-gramatikalean aztertzea. Horretarako, DBH 3ko 34 ikaslek idatzitako testuetan argudiaketa elementuak aztertu dira, Toulminen eredua erabiliz, eta horiek ekoizteko erabilitako baliabide lexiko-gramatikalak diskurtso-analisiaren bidez identifikatu. Emaitzek antzekotasunak erakutsi dituzte hiru hizkuntzen artean, bai argudiaketa-elementuen ekoizpenean, baita baliabide lexiko-gramatikalen erabileran ere.
[en] The train traction, a mainly induction machine dominated sector, is leading towards smaller and more efficient machines in the last years. The permanent magnet machines meet the ideal characteristics in order to accomplish a reduction in size and a boost in the efficiency with respect to the induction machines. In this thesis, a design methodology for permanent magnet machine design for train traction has been developed. Design problems have been identified and the requirements of the application have been studied. Then, a methodology consisting of three stages has been developed; analytical pre-design, finite element analysis and thermal analysis. Initial dimensions are obtained in a rapid way from the analytical pre-design, and these dimensions are then optimized in the finite element analysis stage. Once the electromagnetic design has been verified, the machine is thermally analyzed, verifying that it meets all the thermal requirements. Loss analysis tools that take the effects of the converter into account have been integrated in the methodology with an acceptable level of precision. Furthermore, a magnet loss analysis method that combines the precision of the numerical analysis and the speed of analytical calculation has been developed. The methodology can be used either for surface mounted or interior permanent magnet machines, and considers geared and gearless topologies.Finally, a 120kW prototype has been designed and manufactured for a surface mounted geared machine case and the methodology has been validated by experimental tests.

[eu] Trenen trakzioa, indukzioko makinek menderatzen duten sektore bat, geroz eta makina txikiago eta efizienteagoetara jotzen bideratzen ari da azken urteetan. Iman iraunkorreko makinek ezaugarri egokiak biltzen dituzte indukziozko makinekiko tamainan murrizketa bat eta efizientzian igoera bat lortzeko. Tesi honetan trenen trakziora zuzenduta dagoen imanezko makinen diseinurako metodologia bat garatu da. Diseinuaren problematika identifikatu da eta aplikazioaren errekerimenduak aztertu ondoren, hiru etapatan banatuta dagoen metodologia bat garatua da: aurre-diseinu analitikoa, elementu finituetan analisia eta analisi termikoa. Aurre-diseinu analitikotik lehenengo dimentsioak lortzen dira era azkar batean. Dimentsio hauek elementu finituetako analisi etapan optimizatzen dira. Behin diseinu elektromagnetikoa baieztatua dagoela, makina termikoki aztertzen da, errekerimendu termikoak betetzen dituela baieztatzeko. Metodologiaren barnean bihurgailuarengatiko efektuak kontuan hartzen dituzten galeren kalkulurako erremintak integratu dira, prezisio gradu onargarri batekin. Gainera, imanetan ematen diren galeren analisirako metodo bat garatu da, zenbakizko kalkuluaren zehaztasuna eta kalkulu analitikoaren azkartasuna batzen dituena. Metodologia hau imanak gainazalean zein errotorearen barruan dituzten makinentzat da baliogarria, eta abiadura aldagailudun eta gabeko kasuak aztertzen dira. Azkenik, 120kW-ko prototipo bat diseinatu eta eraiki da imanak gainazalean dituen abiadura aldagailudun makina batentzat eta metodologia entsegu esperimentalen bidez balioztatu da.
