In this thesis a model is developed for calculating the loads on the wetclutches in apowershift transmission. This thesis was done at Volvo CE in Eskilstuna and is focusedon their 4-speed countershaft transmissions. The goal of the project is to be able tocalculate the loads automatically during the transmission tests and thus acquire increasedknowledge about what occurs during operation.The model was developed by first generating a number of concepts and then evalu-ating them to decide which one should be developed further. The chosen concept wasthen developed further and implemented into the test equipment as a calculation script.The chosen loads to model were the energy absorbed in each clutch, the coefficient offriction (COF) and the slip distance. The COF was later found to give too unreliableresults to be used in any other way than as a benchmark for how well the model wasconfigured and to see any large changes in COF.The model was validated by calculating the energy absorbed in a HTE-200 seriestransmission and comparing it to a reference calculation model. It was seen that theresults from the new model are very close to the reference result. The energy lostcalculated by the new model will be equal to 94 % of the energy lost calculated by thereference model, but only when measuring the inertia phase. The energy lost is equalto 135 % when the torque phase is included. The increasing difference is believed tobe because of an error in the reference model that means it does not cover the torquephase.

The aim of this master´s thesis is design of hydralic power shift for transmission Tatra 14TS210L. The master´s thesis contains a description of the individual power shifts used by Tater as well as other truck manufacturers. This is followed by a design concept of the power shift, including FEM calculations of the shift inches and piston rods. Part of the work is also production drawings of the body of the power shift and piston rod.

The high cost of chip testing makes testability an important aspect of any chip design. Two important testability considerations are addressed namely, the power consumption and test quality. The power consumption during shift is reduced by efficiently adding control logic to the design. Test quality is studied by determining the sensitization characteristics of a path to be tested. The path delay fault models have been used for the purpose of studying this problem. Another important aspect in chip design is performance validation, which is increasingly perceived as the major bottleneck in integrated circuit design. Given the synthesizable HDL code, the proposed technique will efficiently identify infeasible paths, subsequently, it determines the worst case execution time (WCET) in the HDL code.

Denna uppsats syfte är att analysera hur musikartister använder sig av YouTube som marknadsföringsverktyg, samt vilken betydelse YouTube har för dessa artisters marknadsföring. En kvalitativ och induktiv metod har tillämpats, medan ett antal intervjuer samt en innehållsanalys genomförts som grund till det empiriska materialet. Detta för att få en inblick i musikbranschens syn på ämnet, samt även ge en objektiv bild av hur plattformen används som marknadsföringsverktyg. Slutligen menade studien att ge artister och andra arbetande inom musikbranschen, en bild av hur användandet av denna marknadsföringskanal kan förbättras för att skapa en mer effektiv marknadsföring.    Den teoretiska referensramen har utgått från tidigare teorier kring YouTubes betydelse, roller och potential inom musikartisters marknadsföring. Teorier kring YouTubes möjliggörande för artister att upptäckas av A&R personer eller nya fans, YouTubes påverkan på musikvideons roll som marknadsföringsmedel, samt teorier kring plattformens påverkan på maktbalansen inom branschen har legat som grund. Även teorier kring ett nytt fokus på opinion leaders; vem och när, samt teorier gällande relationsmarknadsföring, kommunikation, feedback och sampling har tillämpats. Slutligen har teorier kring YouTubes negativa aspekter, såsom svårigheter att sticka ut och illegal spridning setts till. I redogörelsen av det empiriska materialet ingår svar från de intervjuer som genomförts med musikartister samt nyckelpersoner inom branschen. Här redogörs även resultatet från den innehållsanalys som genomförts av de intervjuade artisternas respektive YouTube-kanaler.   I analysen sammankopplas den teoretiska referensramen med det empiriska materialet i en diskussion och analys. Detta för att jämföra tidigare teorier med branschens nuvarande syn på forskningsfrågan samt artisternas faktiska användande av plattformen. Även för att belysa vad musikartisterna har för möjligheter att förbättra sin marknadsföring via YouTube, för en mer framgångsrik marknadsföring.   De slutsatser som uppsatsen sedan mynnar ut i menar att YouTube har utvecklats till en stark marknadsföringskanal för musikartister. Plattformen är av stor betydelse för musikartisters exponeringsmöjligheter, men det krävs dock andra marknadsföringsaktiviteter för att klipp ska hittas av A&R avdelningar och nya fans. Musikvideon har en fortsatt viktig roll för artisternas exponeringsmöjligheter. YouTube skapar en möjlighet till relationsbyggande mellan artister och fans, men denna möjlighet utnyttjas ej till fullo av artisterna. Feedback via kommentarsfält skulle dock kunna nyttjas för större grad av lärande, samt för starkare relationsbyggande. En nackdel är att YouTube dock tycks vara illegal spridning av material, samt minskad kontroll över eget material. Makten över kreativiteten tycks med YouTube ha flyttats mer mot artisterna själva, men de stora aktörernas nätverk och resurser tycks dock fortsatt viktiga för att ge möjligheter att sticka ut i det enorma mediaflödet. / This paper aims to analyze how music artists use YouTube as a marketing tool, and the importance YouTube has for these artists' marketing. A qualitative and inductive approach was used, while a number of interviews and a content analysis conducted as the basis for the empirical material. This to get an insight into the music industry's views on the topic, and also give an objective picture of how the platform is used as a marketing tool. Finally, the study is meant to give artists and others working in the music industry a picture of how the use of this marketing channel can be improved to create a more effective marketing.   The theoretical framework was based on earlier theories of YouTube's importance, roles and potential in music artists' marketing. Theories on how YouTube enables artists to be discovered by A & R people or new fans, YouTube's impact on the music video's role as a marketing medium, and theories about the platform's impact on the balance of power within the industry has been the foundatioin. Theories about a new focus on opinion leaders; whom and when, as well as theories on relationship marketing, communication, feedback and sampling have also been applied. Finally, theories of YouTube's negative aspects, such as difficulties to stand out and illegal distribution has been looked into. In the account of the empirical material responses from the interviews with music artists and key people in the industry are included, as well as the results from the content analysis conducted by the interviewed artists' respective YouTube channels.   In the analysis the theoretical framework is linked to the empirical material in a discussion and analysis. This is to compare previous theories with the industry's current opinions on the research question and the performers' actual usage of the platform, also to illustrate how music artists could improve their marketing through YouTube for more successful marketing.   The conclusions of the essay is of the opinion that YouTube has evolved into a powerful marketing channel for music artists. The platform is of great importance for music artists interms of opportunities of exposure, but additional marketing activities are  however required gor the material to be found by A & R departments and new fans. The music video has a continued important role for artists' exposure opportunities. YouTube creates an opportunity to build relationships between artists and fans, but this opportunity is generally not utilized fully by the artists. Feedback via the comment field could be utilized for greater levels of learning, and for stronger relationship building. One negative aspect of YouTube is that it can be considered as a way to illegaly distribute content, and it does add to reduced control over the artists own material. The creative authority seems with YouTube have moved more towards the artists themselves rather than their labels or management, but networks and resources available to the major labels seem to remain important to provide opportunities to be able stand out in the masses f available media on YouTube.

Axial offset anomaly (AOA) in pressurized water reactors (PWR) refers to deviation of the measured neutron flux in the top half of the core from the predicted values. Among other difficulties, AOA reduces the shutdown margin, and may force the plant to reduce power output. AOA is believed to be caused by three related phenomena occurring in the core while operating at full power: sub-cooled nucleate boiling concentrated mainly in the upper half of the core, corrosion product deposition on the cladding surface (crud), and the deposition of boron within the porous crud layer in regions of vigorous sub-cooled boiling. This study replicates the conditions within the PWR primary coolant; specifically, the temperature, pressure, peak surface heat flux, coolant velocity and water chemistry are simulated in order to produce prototypical crud on an electrically heated Zircaloy-4 test element. At the conclusion of each test run, the heated Zircaloy-4 test element is rapidly isolated from the coolant in order to trap any soluble boron species that may be present in the crud layer. The results of this investigation indicate that prototypical crud with significant boron deposition can be produced. The deposited boron compound has been determined to be lithium tetraborate (Li2B4O7). Comparative experiments have been run to determine the effect of coolant pH, concentration and type of additives, and duration of exposure on the thickness of the crud deposit. The data obtained in this investigation can be used to validate mechanistic models for crud deposition and AOA in pressurized water reactors.

This thesis projct examines the implementation of Artificial Intelligence (AI) in Project Management, focusing on its impact on the working personnel. AI has the potential to improve management processes, increase efficiency, and enhance decision-making. This thesis aims to explore the implementation of AI in project management with a focus on the impact on working personnel. The study analyzes the benefits and challanges of AI implementation, the impact on the role of project managers and team members, and the ethical considerations of using AI in project management. The research incorporates a literature review and semi-structured interviews conducted with project managers from Greece and Sweden to gather comprehensive insights. The findings suggest that the integration of AI in project management can significantly benefit working personnel by reducing workload, increasing accuracy, and providing better insights. However, the implementation of AI requires careful consideration of ethical issues and proper training of personnel. / Detta examensarbete undersöker implementeringen av artificiell intelligens (AI) i projektledning, med fokus på dess inverkan på arbetsgivare. Studien innehåller en literaturgenomgång och semistrukturerade intervjuer med projektledare från Grekland och Sverige för att smala in omfattande insikter. AI har potential att förbättra projektledningsprocesser, öka effektiviteten och förbättra beslutsfattandet. Studien analyserar fördelarna och utmaningarna med AI-implementering, inverkan på rollen för projektledare och teammedlemmar, och de etiska övervägandena av att använda AI i projektledning. Resultatet tyder på att integrationen av AI i projektledning avsevärt kan gynna arbetande personal genom att minska arbetsbelastningen, öka noggrannheten och ge bättre insikter. Men implementeringen av AI kräver noggrant övervägande av etiska frågor och korrekt utbildning av personal.
