Att ta steget in i en dubbel karriär genom ett Riksidrottsuniversitet eller Elitidrottsvänligt lärosäte innebär att en elitidrottare kombinerar deras idrott med akademiskastudier. Föreliggande studies syftade till att undersöka studentidrottares upplevelser av att ha en dubbel karriär och vilka krav, barriärer och resurser de upplever samt hur de hanterarkraven. Den kvalitativa studien bestod av åtta deltagare fördelat på sju kvinnor och en man, i åldrarna 20–35 (M=24,25) som utövade olika idrotter. Studentidrottarnas upplevelser samlades in genom semistrukturerade intervjuer med en intervjuguide utifrån Karriärövergångsmodellen (Stambulova, 2003) och Holistiska idrottsligakarriärutvecklingsmodellen (Wylleman, 2019). Resultatet sammanfattas genom fyra huvudteman: studentidrottares upplevda krav, barriärer, resurser och effektiv hantering. Resultatet visade att studentidrottarna bland annat upplevde höga interna krav från sig själva där de vill lyckas och maximalt prestera i allt de tar sig ann vilket upplevs krävande och stressande. Vidare upplevde de barriärer i form av externa barriärer, begränsad tid och Covid-19 pandemins negativa konsekvenser. Interna tillgångar var målmedvetenhet, erfarenhet och externa tillgångar i bland annat ekonomiskt stöd, dra nytta av andra studenter och ökad flexibilitet med distansstudier. Tre hanteringsstrategier som hjälpte studentidrottarna att hantera denna kombination var problemfokuserad hantering som innebär noggrannplanering för att få ihop livspusslet, undvikande hantering och till sist emotionsfokuserad hantering där personer i deras närhet har störst betydelse men även återhämtning. / Taking the step into a dual career through a National Sports University or Elite SportsFriendly University means that an elite athlete combines their sport with academic studies.The present study aimed to investigate student-athletes' experiences of having a dual careerand what demands, barriers and resources they experience and how they manage the demands.The qualitative study consisted of eight participants divided into seven women and one man,aged 20–35 (M=24.25) who practiced different sports. The student-athletes' experiences werecollected through semi-structured interviews with an interview guide based on The athletictransition model (Stambulova, 2003) and The holistic athletic career model (Wylleman,2019). The results are summarized through four main themes: student-athletes' perceiveddemands, barriers, resources and effective coping. The results showed that the student-athletesexperienced high internal demands from themselves where they want to succeed and performmaximally in everything they do, which is experienced as stressful. Furthermore, theyexperienced barriers in the form of external barriers, limited time and negative consequencesof the Covid-19 pandemic. Internal assets were determination, experience and external assetsin, among other things, financial support, taking advantage of other students and increasedflexibility with distance learning. Three coping strategies that helped the student-athletes dealwith this combination were problem-focused coping which involved planning,avoidant-coping and finally emotion-focused coping.

The purpose of this study was to explore the experiences of elite golf players in transitioning from active professional athletes to post-sports life. All participants in the study were male, playing at one of the two highest national levels in Sweden, either the Future Series or the Moregolf Mastercard Tour. Eight participants were recruited for the study with the requirement that they had played for at least three years at one of these top national levels, and that no more than three years had passed since they ended their careers. The study employed a semi-structured interview guide, developed based on theoretical frameworks, to conduct in-depth interviews with each participant. The information collected from the interviews was analyzed using thematic analysis to identify various themes and patterns, which then formed the results of the study. The results indicated that all participants experienced some form of challenge during their career transition from being active elite athletes to post-sport life. One of the biggest challenges among the participants was uncertainty about the future and what to do after ending their sports careers. Participants found that support from their families was a crucial resource during the end of their careers. Those who had combined sports with studies or work, dual careers, during their active sports careers found that this facilitated their transition. In terms of managing career ending, the majority of the participants highlighted the importance of having a plan B for life after sports. Participants who had not planned for life after sports were worried about their future. However, all but one of the participants began working or studying relatively soon after ending their careers, primarily driven by their own desire to pursue new goals and challenges. / Syftet med studien var att studera elitidrottande golfspelares upplevelser av karriärövergången från aktiv elitidrottare till livet efter idrotten. Samtliga deltagare i studien var herrar som spelat på någon av de två högsta nationella nivåerna i Sverige, Future Series eller Moregolf Mastercard Tour. Åtta deltagare rekryterades till studien, inkluderingskriterierna var att deltagarna skulle spelat minst tre år på någon av de två högsta nationella nivåerna samt att det maximalt fick vara tre år sedan deltagarna avslutat karriären. Studien använde sig av en semistrukturerad intervjuguide konstruerad utifrån de teoretiska ramverken för att genomföra djupgående intervjuer med varje deltagare. Materialet från intervjuerna analyserades med tematisk analys. Resultatet visade tre huvudteman; upplevda utmaningar vid karriäravslut, resurser vid karriäravslut och olika hantering av karriäravslut. En av de största utmaningarna bland deltagarna var osäkerhet om framtiden och vad man ska göra efter idrottskarriären. Deltagarna upplevde bland annat att stödet från familjen var en viktig resurs under karriäravslutet och de deltagare som under den aktiva idrottskarriären kombinerat idrotten med studier eller arbete, upplevde det som en resurs vid karriäravslut. Gällande hantering av karriäravslutet belyste majoriteten av deltagarna vikten av att ha en plan b för livet efter idrotten. De deltagare som inte hade planerat för livet efter idrotten var oroliga över hur det skulle gå för dem. Däremot började alla deltagare förutom en att arbeta eller studera relativt snabbt efter karriäravslutet och en stor anledning till det var framför allt deltagarnas egna driv att sträva efter nya mål och utmaningar.

Syftet med studien är att undersöka upplevelsen av att leva och hantera livet som professionell fotbollsspelare. Det vill säga att studien fokuserade på deltagarnas upplevelser om hur de var att spela fotboll på en professionell nivå och hur de upplevde krav, barriärer, resurser och copingstrategier som påverkade dem både inom fotbollen och i det vardagliga livet utanför deras fotbollskarriär. I studien deltog det nio intervjupersoner där samtliga var män mellan åldrarna 20–32 år (M=26,0, SD=3,20), dessa deltagare befann sig i optimeringsfasen (Wylleman, 2019). Studien har använt sig av en semistrukturerad intervjuguide som har haft sin grund i två modeller, den holistiska karriärsutvecklingsmodellen (Wylleman, 2019) samt Stambulova (2003) karriärövergångsmodellen.             I studiens resultat framkommer det att de krav fotbollsspelarna upplever mest är finansiella krav, där de upplever att de inte kan leva på fotbollen och de behöver ett jobb vid sidan av fotbollen. Den största barriären deltagarna upplevde var främst sociala barriärer eftersom fotbollen tar upp mycket av deras tid, så att deras sociala liv blir lidande. Socialt stöd från vänner,familj, tränare och partner var de största resurserna för deltagarna, de upplevde att stödet från deras närmaste hjälpte dem mycket i deras karriär inom fotbollen samt utanför. De copingstrategier som deltagarna använde sig främst var de sociala copingstrategierna som att gå och prata med någon professionell eller med familj,vänner, tränare eller partner. / The purpose of the study was to investigate the experience of living and managing life as a professional football player. That will say the studies focus is on the participants` experiences of what it is to play football on a professional level and how they experience the demands, barriers, resources and coping strategies that affect them, both in football and in everyday life outside their football career. In the study nine interviewees participated and they were all men between the ages 20-32 years (M= 26.0, SD= 3.20), these participants were in the mastery phase (Wylleman, 2019). The study used a semi-structured interview guide that has been based on two models, the holistic career development model (Wylleman, 2019) and Stambulova (2003) Career transition model.                                 The results of the study show that the demand that football players experience the most are financial demands, where they feel that they can not live on football and need a job alongside. The biggest barrier the participants experienced was mainly social barriers because football takes up a lot of their time, so their social life suffers. Social support from friends, family, coaches and partners was the participants biggest resource, they felt that the support from their loved ones helped them a lot in their careers in football and outside. The coping strategies that the participants used mainly were the social coping strategies such as going to talk to someone professional or with family, friends, coaches or partners.

The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. It is therefore crucial to obtain accurate local metal temperature predictions of the turbine blade. Accurately predicting the external heat transfer coefficient (HTC) distribution of the blade is therefore of uttermost importance. At present time, Siemens Energy uses the boundary layer code TEXSTAN for this purpose. The limitations coupled to such codes however make them less applicable for the complex flow physics involved in the hot gas path of turbine blading. The thesis therefore aims at introducing CFD for calculating the external HTC. This includes conducting an extensive literature study to find and validate a suitable methodology. The literature study was centered around RANS modeling, reviewing how the calculation of the HTC has evolved and the performance of some common turbulence and transition models. From the literature study, the SST k − ω model in conjunction with the γ − Reθ transition model, the v2 − f model and the Lag EB k − ε model were chosen for the investigation of a suitable methodology. The validation of the methodology was based on the extensively studied LS89 vane linear cascade of the von Karman Institute. In total 13 test cases of the cascade were chosen to represent a wide range of flow conditions. Both a periodic model and a model of the entire LS89 cascade were tested but there were great uncertainties whether or not the correct flow conditions were achieved with the model of the entire cascade. It was therefore abandoned and a periodic model was used instead. The decay of turbulence intensity is not known in the LS89 cascade. This made the case difficult to model since the turbulence boundary conditions then were incomplete. Two approaches were attempted to handle this deficiency, where one was ultimately found invalid. It was recognized that the Steelant-Dick postulation could be used in order to find a turbulent length scale which when specified at the inlet, lead to fairly good agreement with data of the HTC. The validation showed that the SST γ − Reθ model performs relatively well on the suction side and in transition onset predictions but worse on the pressure side for certain flow conditions. The v2 − f model performed better on the pressure side and on a small portion of the suction side. Literature emphasized the importance of obtaining proper turbulence characteristics around the vane for accurate HTC-predictions. It was found that the results of the validation step could be closely coupled to this statement and that further work is needed regarding this. Further research must also be done on the Steelant-Dick postulation to validate it as a reliable method in prescribing the inlet length scale.

While FPGAs provide flexibility for performing high performance DSP functions, they consume a significant amount of power. Often, a large portion of the dynamic power is wasted on unproductive signal glitches. Reducing glitching reduces dynamic energy consumption. In this study, retiming is used to reduce the unproductive energy wasted in signal glitches. Retiming can reduce energy by up to 92%. Evaluating energy consumption is an important part of energy reduction. In this work, an activity rate-based power estimation tool is introduced to provide FPGA architecture independent energy estimations at the gate level. This tool can accurately estimate power consumption to within 13% on average. This activation rate-based tool and retiming are combined in a single algorithm to reduce energy consumption of FPGA designs at the gate level. In this work, an energy evaluation metric called energy area delay is used to weigh the energy reduction and clock rate improvements gained from retiming against the area and latency costs. For a set of benchmark designs, the algorithm that combines retiming and the activation rate-based power estimator reduces power on average by 40% and improves clock rate by 54% for an average 1.1x area cost and a 1.5x latency increase.

À l’ère de la mondialisation institutionnelle des sociétés modernes, alors que la confluence d’une myriade d’influences à la fois micro et macro-contextuelles complexifient le panorama sociopolitique international, l’intégration de l’idéal participatif par les processus de démocratisation de la santé publique acquiert l’apparence d’une stratégie organisationnelle promouvant la cohésion des multiples initiatives qui se tissent simultanément aux échelles locale et globale. L’actualisation constante des savoirs contemporains par les divers secteurs sociétaux ainsi que la perception sociale de différents risques conduisent à la prise de conscience des limites de la compétence technique des systèmes experts associés au domaine de la santé et des services sociaux. La santé publique, une des responsables légitimes de la gestion des risques modernes à l’échelle internationale, fait la promotion de la création d’espaces participatifs permettant l’interaction mutuelle d’acteurs intersectoriels et de savoirs multiples constamment modifiables. Il s’agit là d’une stratégie de relocalisation institutionnelle de l’action collective afin de rétablir la confiance envers la fiabilité des représentants de la santé publique internationale, qui ne répondent que partiellement aux besoins actuels de la sécurité populationnelle. Dans ce contexte, les conseils locaux de santé (CLS), mis en place à l’échelle internationale dans le cadre des politiques régionales de décentralisation des soins de santé primaires (SSP), représentent ainsi des espaces participatifs intéressants qui renferment dans leur fonctionnement tout un univers de forces de tension paradoxales. Ils nous permettent d’examiner la relation de caractère réciproque existant entre, d’une part, une approche plus empirique par l’analyse en profondeur des pratiques participatives (PP) plus spécifiques et, d’autre part, une compréhension conceptuelle de la mondialisation institutionnelle qui définit les tendances expansionnistes très générales des sociétés contemporaines. À l’aide du modèle de la transition organisationnelle (MTO), nous considérons que les PP intégrées à la gouverne des CLS sont potentiellement porteuses de changement organisationnel, dans le sens où elles sont la condition et la conséquence de nombreuses traductions stratégiques et systémiques essentiellement transformatrices. Or, pour qu’une telle transformation puisse s’accomplir, il est nécessaire de développer les compétences participatives pertinentes, ce qui confère au phénomène participatif la connotation d’apprentissage organisationnel de nouvelles formes d’action et d’intervention collectives. Notre modèle conceptuel semble fournir un ensemble de considérations épistémosociales fort intéressantes et très prometteuses permettant d’examiner en profondeur les dimensions nécessaires d’un renouvellement organisationnel de la participation dans le champ complexe de la santé publique internationale. Il permet de concevoir les interventions complexes comme des réseaux épistémiques de pratiques participatives (RÉPP) rassemblant des acteurs très diversifiés qui s’organisent autour d’un processus de conceptualisation transculturelle de connaissances ainsi que d’opérationnalisation intersectorielle des actions, et ce, par un ensemble de mécanismes d’instrumentalisation organisationnelle de l’apprentissage. De cette façon, le MTO ainsi que la notion de RÉPP permettent de mieux comprendre la création de passages incessants entre l’intégration locale des PP dans la gouverne des interventions complexes de la santé et des services sociaux – tels que les CLS –, et les processus plus larges de réorganisation démocratique de la santé publique dans le contexte global de la mondialisation institutionnelle. Cela pourrait certainement nous aider à construire collectivement l’expression réflexive et manifeste des valeurs démocratiques proposées dans la Déclaration d’Alma-Ata, publiée en 1978, lors de la première Conférence internationale sur les SSP. / In an age of the institutional globalization of modern societies, the confluence of a myriad of micro- and macro-contextual factors complicates the international socio-political arena. In this context, the integration of participatory values through the democratization processes of Public Health takes on the appearance of an organizational strategy promoting cohesion among a multitude of local and global initiatives. The constant renewal of intersectoral knowledge and the social perception of risk suggest an increased social awareness regarding the limits of technical competence of social and healthcare Systems. As a legitimate international actor in the management of modern health risks, Public Health creates participatory spaces that enable interaction of intersectoral actors and constantly changing and dynamic knowledge. It is indeed a strategy of the institutional “relocalisation” of collective action, aiming to restore trust in the level of reliability of international Public Health representatives who only partially meet the current needs of population security. In this context, Local Health Councils (LHC), implemented internationally as part of decentralized Primary Health Care (PHC) regional policies, represent participative spaces that involve countless paradoxical forces of tension. The LHC provides both an opportunity to examine the reciprocal relationship between an in-depth empirical analysis of specific participatory practices (PP), as well as a conceptual comprehension of the institutional globalization defining the general expansionist tendencies of modern societies. Using the organizational transition model (OTM), we postulate that the integration of PP into LHC governance is potentially associated with organizational change in creating both the conditions and the consequences of numerous strategic and systemic translations, which are essentially transformative. However, in order for this transformation to occur, relevant participative skills need to be developed. Consequently, this participative phenomenon takes on the shape of an organizational learning process allowing new forms of collective action and intervention to be accomplished. Our conceptual model offers a set of interesting and promising “epistemosocial” considerations for an in-depth examination of the dimensions essential for an organizational renewal of participation in the complex field of Global Health. Through the OTM, we conceive complex interventions as epistemic networks of participative practices (ENPP) composed of a wide range of actors organized around a double process of transcultural conceptualization of knowledge and inter-sector operationalization of action. This process is possible through a set of mechanisms of organizational instrumentation of learning. In this way, the OTM and the concept of ENPP allow for a better understanding of the unceasing transition between the local integration of PP in the governance of complex interventions in the field of health and social services – such as LCH – and the broader processes of democratic reorganization of Public Health in a global context of institutional globalization. This could certainly help us to collectively construct a reflexive and manifest expression of democratic values proposed in Alma-Ata Declaration published in 1978 during the first International Conference on PHC.
