In today’s lighter vehicles, EPS has had smaller breakthroughs, but not in heavyduty due to its high initial cost and lack of research. Even though there ispotential in the future when trucks may go electric. In this report, the theoreticalrequirements to implement an EPS system will be determined and investigatedalong with an in depth analysis of the electrical motor and planetary gearbox used.A preferred EPS system will consist of a Permanent magnet electric motor and aplanetary gearbox with optimized characteristics regarding voltage, cost, shape,dimensions and layout. The results lead to a theoretical EPS system that can befitted into a heavy duty truck’s engine compartment. Problems with implementingEPS, such as cost, electrical issues and limited space as well as possibilities forfuture work are discussed.

The digital development of the 1990s and early 2000s had a major effect on the Swedish media industry, including newspapers. Still, it is not clear what role academia had during this process. Therefore, the purpose of this thesis is to examine the role of the university in the digital development of the Swedish news media industry. To investigate this, a case study has been performed, focusing on the Swedish technical university KTH Royal Institute of Technology. A theoretical background was created, consisting of the three waves of digitalization by Yoo et al. (2010), the emerge of the entrepreneurial university, and the Triple Helix model. Data were collected through archival research consisting of the Swedish magazines Ny Teknik and Pressens Tidning, and semi-structured interviews with seven individuals. The results showed that the digital development of the Swedish news media industry was characterized by the rise of the Internet, which generated both new news channels and contributed to digitally develop the printing industry. The results indicate that KTH’s role in this development was to provide the industry with well-educated engineers as well as innovations through research projects, to help media companies handle the opportunities and the challenges the digital development offered. The results also indicate that KTH in some ways can be compared to an entrepreneurial university, since the university has contributed to economic activities in society. However, most of these activities would not have been possible without the participation of the media industry, demonstrating that the concept of the Triple Helix to some extent also can be applied to this case study. / Den digitala utvecklingen av 1990- och tidigt 2000-tal hade en stor effekt på den svenska medieindustrin, inklusive tidningsindustrin. Det är dock inte klart vad för roll universiteten hade under denna process. Syftet med denna uppsats är därför att undersöka universitetets roll i den digitala utvecklingen av den svenska nyhetsmedieindustrin. För att undersöka detta har en fallstudie genomförts, som fokuserar på det svenska tekniska universitetet KTH Kungliga Tekniska Högskolan. En teoretisk bakgrund togs fram, bestående av de tre vågorna av digitalisering av Yoo et al. (2010), framväxten av det entreprenöriella universitetet och modellen Triple Helix. Data samlades in genom arkivforsknings bestående av de svenska tidningarna Ny Teknik och Pressens Tidning, samt semistrukturerade intervjuer med sju personer. Resultaten visade att den digitala utvecklingen av den svenska nyhetsmedieindustrin karaktäriserades av uppkomsten av Internet, vilket genererade både nya nyhetskanaler och bidrog till en digital utveckling av tryckeribranschen. Resultaten indikerar att KTH:s roll i denna utveckling bestod av att bidra med välutbildade ingenjörer till industrin, likväl som innovation genom forskningsprojekt, vilket hjälpte industrin hantera möjligheterna och utmaningarna som den digitala utvecklingen medförde. Resultaten indikerar också att KTH i viss utsträckning kan jämföras med det entreprenöriella universitetet, eftersom universitetet har bidragit till ekonomiska aktiviteter i samhället. De flesta av dessa aktiviteter hade dock inte varit möjliga utan medieindustrins delaktighet, vilket demonstrerar att modellen Triple Helix i viss utsträckning kan appliceras på denna fallstudie.

A variety of demands have to be considered in the design of a new opera house in Galärvarvet. All possible viewpoints are important to be aware of, as is the need for the new building to be a contrast to the already existing opera house in Stockholm. The restricted site also makes a multitude of demands on the building's design. By rationalizing the layout and structure and also by making the footprint smaller, the complex building of over 30 000 square meters can be fitted and blended into the existing physical context. Unlike the existing opera house in Stockholm, the new opera house shows the rationality and the advanced technology that lies behind the scenes and becomes the character of the entire building. Through the dynamic façade, the new opera can convey any character it so desires, just like scenes do through different settings. The result is that the new opera house helps present the magic of any opera performance of any era or artistic content. / En ny operabyggnad i Galärvarvet ställer en rad olika krav på byggnaden. Den måste inte bara kunna betraktas från många olika vinklar och avstånd, utan också stå i kontrast till den redan befintliga operabyggnaden i Stockholm. Den trånga tomten ställer också en rad olika krav på byggnadens utformning. Genom att rationalisera planlösningen, strukturen och våga bygga på höjden kan det komplexa projektet på över 30 000 kvm få plats på tomten och smälter skalmässigt in i miljön. Till skillnad från den befintliga operan i Stockholm, knyter den nya Galäroperan an till rationaliteten och den avancerade tekniken som döljer sig bakom scenerna och görs här synlig för besökarna. Genom den smarta fasaden kan Galäroperan inta vilken karaktär den så önskar, på samma sätt som scenen ändrar karaktär genom scenografi. Galäroperan blir på så sätt spännande att betrakta från olika perspektiv och den dynamiska fasaden hjälper till att föra fram operans magi.

This Master Thesis is the research done in the country of Rwanda. The project leads to study the climate of this country in order to establish whether this climate could be used to produce energy from air and to implement the first wind turbine for serving the nation.   After an introduction about the historical background of wind power, the thesis work deals with assessment of wind energy potential of Rwanda in focusing of the most suitable place for wind power plants. The best location with annual mean wind speed, the rate of use of turbine with hub height for an annual production per year, the mean wind speeds for 6 sites of Rwanda based on ECMWF for climatic data for one year at relief of altitude of 100m and coordinates are reported too.   The result of energy produced and calculations were done based on power hitting wind turbine generator in order to calculate Kinetic energy and power available at the best location to the measurement over the period of 12 months, that could be hoped for long term.   With help of logarithmic law, where wind speed usually increases with increasing in elevation and the desired wind speeds at all 6 sites were used. The annual energy production was taken into account at the best site with desired wind speed at the initial cost of turbine as well as the cost of energy (COE).However, with comparison of the tariff of EWSA, the price of Wind designed in this Research per kWh is cheaper and suitable for people of Rwanda. / <p><em>Rwanda has considerable opportunities development energy from hydro sources, methane gas, solar and peat deposits. Most of these energy sources have not been fully exploited, such as solar, wind and geothermal. As such wood is still being the major source of energy for 94 per cent of the population and imported petroleum products consume more than 40 per cent of foreign exchange. Energy is a key component of the Rwandan economy. It is thus recognized that the current inadequate and expensive energy supply constitutes a limiting factor to sustainable development. Rwanda’s Vision 2020 emphasizes the need for economic growth, private investment and economic transformation supported by a reliable and affordable energy supply as a key factor for the development process. To achieve this transformation, the country will need to increase energy production and diversify into alternative energy sources. Rwandan nations don’t have small-scale solar, wind, and geothermal devices in operation providing energy to urban and rural areas. These types of energy production are especially useful in remote locations because of the excessive cost of transporting electricity from large-scale power plants. The application of renewable energy technology has the potential to alleviate many of the problems that face the people of Rwanda every day, especially if done so in a sustainable manner that prioritizes human rights.</em></p>
