[en] Noise and vibration of electrical machines is a major concern. Changes in the machine design to improve its ef f iciency can lead to unacceptable vibrations. Tools to predict its vibratory and acoustic performance at the design stage need to be developed. An improved f inite element model has been developed to analyse the vibration behaviour of a permanent magnet synchronous motor (PMSM) using the f inite element software ABAQUS. All components and subsets of the machine have been modelled and validated by experimental modal analysis (EMA) performed on them. Some modelling issues have been overcome so that an accurate enough model has been reached. The laminated stator, as it is formed by a pack of several steel sheets, has been treated as an orthotropic material and windings have been considered a solid orthotropic part as well. The rotor-shaf t assembly has also been verif ied by EMA. The bearings that join the rotor to the assembly of the stator have been represented by radial springs. The electromagnetic forces are applied to the whole machine model in order to obtain the vibration response. These forces are obtained from the magnetic air-gap flux density which has been obtained with a 2D f inite element model developed by FLUX. Finally, it has also been obtained the experimental acoustic power that the machine emits.

[eu] Makina elektrikoen zarata eta bibrazioa kezka garrantzitsuak dira. Beronen efizientzia hobetzeko burututako aldaketek bibrazio maila onartezin bat ekar dezakete. Ondorioz, makina hauen portaera bibroakustikoa aurreikusiko duten erremintak garatzea nahitaezkoa da. ABAQUS softwarearen laguntzaz, iman iraunkorreko motor sinkrono baten bibrazio portaera aztertzeko modelo bat garatu da, elementu finituen metodoa erabiliz. Makinaren osagai eta azpimultzo guztiak analisi modal esperimentalen (AME) bidez balioztatuak izan dira. Gainera, modelizazio aspektu batzuk hobetu egin dira, beraz modelo fidagarri bat sortu da. Estatore laminarra, altzairuzko zenbait xaflez osatuta dagoenez, material ortotropo bat bezala kontsideratu da, eta harilkatua ere solido ortotropo bezala kontsideratu dira. Errotore-ardatz azpimultzoa ere AME-ren bidez balioztatua izan da. Bestalde, errotorea multzoarekin lotzen duten errodamenduak malguki erradial batzuen bidez modelizatu dira. Gainera, bibrazioaren erantzuna zein den lortzeko, makina osoaren gain indar elektromagnetikoak aplikatu dira. Indar hauek estatore eta errotorearen hortz eta poloen artean dagoen fluxu magnetikoaren dentsitatearen bidez lortu dira. Horretarako, 2Dko elementu finituen modelo bat garatu da FLUX-en. Amaitzeko, igorritako potentzia akustikoaren neurketa esperimentala ere burutu da. Hitz gakoak: Motor elektrikoak, Bibrazioak, Inposatutako erantzuna, Zarata elektromagnetikoa.
[en] In the following pages, presents the research concerning the Corporate Management Model of Mondragon Group. This model is based on the paradigm of quality and has been implemented in cooperative group from the early 90s. To carry out the investigation, has followed a sociological perspective based on neo-institutional theory. Regarding the methodology used, this has been a combination of a longitudinal analysis with the case study applied to Ederlan Fagor cooperatives and AMPO, both cooperatives of reference within the Mondragón Group, although the latter came out in 2008. The longitudinal analysis on the one hand, will allow us to know the origin of the Mondragon Cooperative Experience as a social construction and its evolution over time, from the analysis of the cognitive, normative and regulate aspects. Moreover, the case study will reveal the adequacy and implementation of the Corporate Management Model to two specific organizational and institutional realities that have followed its own development. Thus, the cooperative Fagor Ederlan has chosen the implementation of lean manufacturing, while the cooperative AMPO has opted for re-engineering and leadership. In this way, each of them has tried to optimize its business results at achieving economic efficiency and the organizational and institutional change.

[eu] Ondorengo orrietan, Mondragon Taldeko Gestio Eredu Korporatiboaren inguruan ekindako ikerketa jasotzen da. Gestio Eredu Korporatiboa kalitatearen paradigman oinarrituta dago eta 90. hamarkadatik aurrera Taldeko kooperatibetan implementatu izan zen. Ikerketa hau gauzatzerakoan, ikuspegi soziologikoa jarraitu da eta teoria neoinstituzionala izan da aukeratutako oinarri teorikoa. Metodologiari dagokionez, alde batetik analisi longitudinala eta bestetik, Fagor Ederlan eta AMPO, kooperatibak aztertzerakoan, "case study" metodologia aplikatu izan da. Analisi longitudinalaren bidez, Arrasateko Esperientzia Kooperatiboa eraikuntza sozial gisa ulertuta, bere sorrera eta eboluzioaren berri izango dugu, alderdi kognitiboak, normatiboak eta reguladoreak kontutan izanik. "Case study" metodologiak berriz, Gestio Eredu Korporatiboa nola egokitu eta inplementatu den antolakuntza zehatzei ezagutzeko aukera emango digu. Egokitze horretan, kooperatiba bakoitzak bere eredu propioa garatu du. Horrela, Fagor Ederlan kooperatibak, lean manufactuting sistema aplikatu du, bere ereduaren ezaugarri nagusiena bihurtuz. AMPO kooperatibak berriz, reingenieria eta lidergoaren bidea aukeratu du. Era honetan, kooperatiba biek, helburu sozioekonomikoak hobetu eta eraldaketa organizatiboa eta instituzionalaren bidetik abiatu dira. Biek Mondragón Taldeko kooperatibak izateagatik nabarmendu dira nahiz eta AMPOk 2008.urtean Taldetik atera zen.
[en] In this thesis it has been investigated the effectiveness of using shape memory alloys to improve the performance of composite materials under impact loads. This task has been carried out on two fronts, the understanding of the thermomechanical behavior of NiTi at impact strain rates, and the using of this knowledge to manufacture a composite material pCBT/FC/NiTi, in which the reinforcement of NiTi increases the energy absortion at impact and improves the damage tolerance of the composite. To reach this goal, it has been necessary the developement of a specific characterization methodology for impact strain rates, which is able to obtain fundamental properties of materials at strain rates between 1 and 103 s-1, with higher accuracy than employing the conventional tensile-impact test; and the developement of a phenomenological model that can predict the mechanical behavior of NiTi at impact.

[eu] Ondorengo tesian, material konposatuen talkarekiko portaera hobetzeko, "forma memoriadun aleazioen" erabileraren eraginkortasuna aztertu da. Hau burutzeko, alde batetik NiTi-ren portaera termomekanikoaren ezagutzan sakondu da eta bestalde, ezagutza hau erabiliz, pCBT/FC/NiTi material konposatu berria fabrikatu da. Material honetan, NiTi-ren errefortzuak, talka aurrean energia xurgatzeko gaitasuna haunditzen du eta konposatuaren kaltearekiko tolerantzia hobetzen du. Honetarako, beharrezkoa izan da 1 eta 103 s-1 abiadura bitarteetan materialen funtsezko propietateak eskuratzeko gai den talka karakterizazio metodologi espezifiko baten garapena, honen zehaztasuna, ohizko talka-trakzio saiakuntza baino haundiagoa delarik. Beharrezkoa izan da ere, talka aurrean NiTi-ren portaera mekanikoa iragartzeko gai den izaera fenomenologikodun eredu baten garapena.
[en] The aim of this study was to explore audiovisual consumption in teenagers aged from 12 to 16 in 2011 in the province of Gipuzkoa (Basque Country). Given the crucial role of peers in teenager development, the relationship between individual and peer group media consumption patterns has been studied. The impact of the digitizing audiovisuals through new ways of consumptions was also assessed. Data was gathered through a survey carried out on 852 subjects throughout the province, 26 in-depth interviews and the content analysis of 16 Tuenti social media profiles. Results helped us conclude that old and new audiovisual consumption patterns coexist after the digitalization. In addition, the influence of peers on the adolescent media consumption is remarkable.

[eu] Ikerlan honen helburua da ezagutzea 12 eta 16 urte bitarteko gaztetxo gipuzkoarren ikusentzunezko kontsumo-ohiturak, betiere nerabezaroan funtsezkoa den lagun-taldearekin duen harremana kontuan hartuta (jakiteko ea harremanik dagoen ikus-entzunezko kontsumo indibidualaren eta talde-kontsumoaren artean). Landa lana 2011n burutu zen: 852 galdetegi, 26 sakoneko elkarrizketa eta 16 neraberen Tuentiko profilen eduki-azterketa baliatu ziren ikerketa osatzeko. Ikerlanak deskribatzen duen testuinguruan aro analogikoko ikus-entzunezko praktikak eta kontsumo-ohitura berriak uztartzen dira, digitalizazioaren ondorioz sortu direnak. Horrekin batera, lagun-taldearen eragina nerabezaroan nabaria da.
[en] After exposing the shortcomings of regional innovation systems and smart specialisation strategies with regard to the technical training, the provision of technological services to SMEs and local development, this paper shows how Vocational Education and Training (VET) centres could contribute to solve them. For that, it is necessary to turn unitary VET centres into multi-functional VET centres. The performance of the new non-traditional functions by the VET centres depends on the prevalent type of centre, and internal and external factors to them. The analysis of the case of Navarre allows us, on top of illustrating the previous points, to draw some orientations about how the transformation of the VET centre model should be undertaken.

[en] This article examines the different forms of consumption and interaction that young people employ with television and online video content. The aim of this study is to know whether audience behaviour changes depending on the type of medium. The study presents the most significant statistical results of a survey of 475 young students conducted at Mondragon University. After carrying out a factorial analysis and two multiple generalized linear regressions, our results show that it is statistically impossible to describe audience attitude as a dichotomy between passive television viewers and active internet users.

[en] In a precarious socio-labor reality, The Mondragon Cooperative Experience remains as an organizational and mode of production alternative. However, there are so many sociological differences between the first generation of cooperative members and the young generations coming to work. Cultural values, identification processes and social meanings of the Cooperative Model are changing. In this research, we investigate the way of cooperativism transmission is happening in young generations, pointing out the social definitions of cooperativism and its strategic challenges.

[en] In recent years, due to the socio-economic development, the wishes of the society have been changing. Nowadays, instead of material goods, the society is looking for emotional and social goods. As a consequence, the market has developed beyond products and services, focusing on offering Experiences. So in design, as it is a discipline directly connected to the environment, the same development has occurred. However, in industry there is still a long way to go in order to integrate the concept of Experience in their developments. Therefore, there is a big gap regarding to Experience Design methods and tools for the industrial digital systems. In this context, Diseinu Berrikuntza Zentroa of Mondragon University (DBZ-MU) together with DANOBATGROUP S.COOP, is working on the creation of new tools for the development of the Experiences of those digital systems. In this article, one of those tools is presented, the User Interface Experience Capturer (UIEC). Thanks to this tool it is possible to capture the experiences that the user has with the interactive systems, so that way afterwards an interaction that fulfils the motivations and emotional needs of the user could be created.

[eu] Azken urteotako aldaketa sozio-ekonomikoa dela eta, gizartearen nahiak aldatuz joan dira. Gaur egun, behar materialak baino, gizarteak beharrizan emozional eta sozialak betetzea ditu helburu, ondorioz, merkatuak produktu eta zerbitzuetatik haratago doan eboluzioa jasan du, esperientziak eskaintzean zentratuz. Neurri berean, diseinuan, inguruari guztiz lotutako disziplina izanik, esperientziaren alorrean ari da lanean. Hala ere, industria, behar guztiz materialetara zuzenduta egonik, egoera honetara egokitzeke dago oraindik. Horren erakusle, bertako inguru digitaletako esperientzien diseinurako metodo eta erraminten hutsune handia dagoela identifikatu da. Kontestu honen baitan, Mondragon Unibertsitateako Diseinu Berrikuntza Zentroa (DBZ-MU) DANOBATGROUP S.COOP-ekin elkarlanean, inguru digital horien esperientziara bideratutako erraminten sorreran ari da lanean. Horren adibide da artikulu honetan aurkezten den erraminta, Erabiltzaile Interfazeen Esperientzia Hartzailea (EIEH). Erraminta honi esker, erabiltzaileak sistema interaktiboekin dituen esperientziak jasotzen dira, ondoren bere motibazioak betetzen dituen eta lotura emozional eraginkorragoa ahalbidetzen dituen interakzio berriak diseinatu ahal izateko.
[en] Ageing of the population together with the increase of life's quality in developed societies, has lead to a change of population needs from the health point of view. Dentist placing dentures are increasingly fewer, since the large development in oral implantology has attributed a sign of quality and durability to dental implants. However, the exigency level and product life tend to increase, which attracts attention to the development of more durable materials and surfaces and more compatible, from mechanical and biological viewpoint. In this thesis dissertation, a promising alloy in the area of oral implantology has been characterised. Ti13Nb13Zr alloy has not only a much many similar mechanical properties comparing to the bone, but it also has biocompatible alloying elements. Corrosion and tribocorrosion characterisation of the alloy has been carried out to study the mechanical request due to mastication events in an aggressive environment such as saliva. Results were very similar to the widely used materials, i.e. commercially pure titanium, which converts Ti13Nb13Zr alloy in candidate material for oral implantology applications. Two different ways have also been studied to enhance metal protection. On the one hand, the addition of corrosion inhibitors through mouth-rinses, an innovative faith that could became an essential accessory to control corrosion and alloy degradation. On the other, thermal oxidation of Ti13Nb13Zr, a cost effective thermal treatment, that has shown to reduce the degradation rate in more than a 200 %.

[eu] Osasunaren ikuspuntutik, biztanleriaren zahartzeak eta bizitza kalitatearen igoerak biztanleriaren beharrak aldatzera eraman dituzte. Gero eta dentista gutxiagok hortzordeak jartzen dituzte hortzik gabeko pazienteetan. Honen arrazoi nagusia, inplantologia oralaren garapena hortz inplanteetan jarri duen kalitate zeinua eta iraunkortasuna izan da. Hala ere, eskakizun mailek eta produktuaren bizitzak handiagotze joera dute eta materiala edota gainazal iraunkorragoak eta bateragarriagoak, bai mekanikoki eta biologikoki, garatu behar dira. Tesi doktoral honetn, hortz inplanteetan erabiltzeko aleazio berri bat karakterizatu dugu. Ti13Nb13Zr aleazioak hezurrarekiko propietate mekaniko antzekoagoak izateaz gain, aleazio elementu biokonpatibleak ere badauzka. Hortz inplanteek mastikazioa jasan behar dutenez ingurune oldarkor batean (listua), korrosio eta tribokorrosioarekiko karakterizazioa aurrera eraman dugu. Lortutako emaitzak, egun asko erabiltzen den materialaren antzekoak izan dira, CpTi4. Beraz, Ti13Nb13Zr aleazioa inplantologia oralerako material hautagaia bihurtzen da. Are gehiago, materialaren babesa sustatzeko bi alternatiba ikertu dira. Alde batetik, korrosio inhibitzaileak listuan gehitzea irakuzketen bidez; apustu interesgarri bat, nahitaezko osagarri batean bihurtu litekeela inplanteen korrosio eta degradazioa kontrolatzeko. Bestalde, oxidazio termikoak Ti13Nb13Zr aleazioan, tratamendu termikoa kostu lehiakorrean, materialearen degradazio abiadura % 200-ean murriztea erakutsi du.
