There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

Inom svensk process- och tillverkningsindustri finns det stora mängder spillvärme som sällan kommer till användning. Att hitta olika tekniska lösningar för att effektivt tillvarata denna spillvärme skapar både nytta ur ett hållbart perspektiv samt ur ett ekonomiskt perspektiv för företaget.I denna rapport presenteras en utarbetad beräkningsmodell i Excel. Beräkningsmodellen används för att uppskatta lönsamheten för anläggning av ett högtemperaturlager i berggrunden. Excel-filen ska kunna användas för företag som en första uppskattning om ett borrhålslager är ett alternativ för tillvaratagande av spillvärme. Utformningen av beräkningsmallen utgick från Xylems högtemperaturlager i Emmaboda.Beräkningsmallen testades på Xylems borrhålslager.

Detta arbete kretsar kring obemannade luftfartyg, UAV, avsedda att baseras ombord påörlogsfartyg. Regelverk och standarder tillsammans med befintliga fartygs-, helikopter- ochUAV-system utgör ett ramverk inom vilket ett scenario leder fram till grundläggande tekniskakrav för de delsystem som ingår i ett fartygsbaserat UAV-system. Kraven, som är framtagnamed spårbarhet i sjöoperativa förmågor, erfarenheter från den miljö ett luftburet system skaverka i ombord och systemexempel som visar vad som är möjligt att uppnå med dagenstekniknivå, presenteras som ett förslag till värderingskriterier och effektmått med tyngdpunktpå de krav som ställs på luftfartyget (UAV) i sig..

Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..

The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.

The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.

We have performed a case study on Acne Jeans, a creative Swedish fashion company, which initiated a cooperation with the Swedish venture capital firm Öresund. The aim of our paper was to examine what motivates a venture capital firm to transform the management control system of a creative company, into a more formal system of control. Main results: Öresund did not have an excessive impact on the management control system of Acne Jeans, due to three main reasons. First of all, Acne Jeans had a satisfactory management control system prior to the cooperation. Furthermore, the relationship between the two parties was characterized by mutual trust.

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.
