Det problem som denna uppsats hade för avsikt att besvara var varför hemautomation inte används i fler hem. Genom resultaten från en enkät som distribuerades kunde slutsatsen att kostnaden för de befintliga lösningar som finns på marknaden idag inte låg i den prisklass våra respondenter ansåg rimlig. Författarna utvecklade då problemet och ställde sig frågan om en hemautomationslösning verkligen måste ha en så hög kostnad som de befintliga lösningarna har idag. För att belysa detta problem implementerades en egen kostnadseffektiv lösning där respondenternas mest önskvärda funktioner togs i beaktande och en testmiljö implementerades utefter dessa. Resultatet blev en hemautomationslösning med stor potential och med en betydligt lägre kostnad än dagens befintliga lösningar..

The municipality of Kalmar have a problem, how to reach and communicate with young people in Kalmar. In today?s changing media environment it gets more difficult to stand out and reach audience with messages and especially with the new forms of media that has revealed. Therefore, we have been commissioned to develop recommendations on how the municipality of Kalmar can communicate with young people in Kalmar.  The purpose with this study is to investigate which media channels young people in Kalmar use and their attitudes towards social media in particular. We wanted to find out how the municipality should communicate to reach them and what attitude youths have against the municipality in general.

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

The purpose of this paper is to analyze Martti Ahtisaari?s comprehensive reportfor Kosovo, CPS, based on theories about democracy, democratization andmulticulturalism. The essay is a way to make a contribution to research on howthe international community can contribute to democratization processes ingeneral, as the CPS gives the expression and democratization of contextscharacterized by multicultural problems in particular. In this paper, we implementa qualitative text analysis of our main material CPS. The qualitative text analysiscan be applied in studies as ours when sought contents of the text are hidden underthe surface.

I have studied how network in a broad sense can affect decision-making. The primary purpose is to see if the political initiative somewhere disappears when it comes to understand the relations between power, actors and politics. The study discuss in a theoretical area that concerns the reliability in neoinstitutionalism to use as an analytical instrument. Some criticism is given to the theoretical standpoint in the sense that there is no power perspective included in the theory. I include a discussion about a concept of power, which I include to the theory.

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

SAMMANFATTNING När man i tidigare undersökningar studerat betesgång för mjölkkor har klimatet på betet inte beaktats. En höglakterande ko producerar mycket värme som hon måste avge till sin omgivning för att kunna bibehålla sin kroppstemperatur. De sätt som djuret kan avge värme på är begränsade och påverkas av flera klimatfaktorer samt djurets genetiska och biologiska förutsättningar. Antalet dagar som registreringar gjordes under denna studie blev av flera olika anledningar få, 18 dagar. Klimatet utomhus under studien registrerat som globtemperatur varierade från 22,4 till 34,7ºC. Då djurskyddslagen skall främja djurens hälsa och djurets naturliga beteende fick en grupp 126 höglakterande kor möjlighet att välja uppehållsplats under tiden 26 juli till 11 augusti. 2004. Korna fördes ut på betet vid niotiden på förmiddagen och var därefter fria att gå in och ur stallet efter egen vilja tills de togs in för kvällsmjölkning omkring klockan tre påeftermiddagen.

If you have access to wood, a wood burning boiler is a cheap way to heat your home, but it is certainly not the most convenient option. Wood requires many operations and management, which takes time. One way to reduce this workload is to have a modern boiler with automatic ignition. Enertech/CTC has a desire to create an accessory with automatic ignition to a modern wood burning boiler. Today there is no boiler on the market that can ignite firewood automatically without the introduction of paper and sticks.

Every year, approximately 700 000 individuals´ visit an emergency ward in Sweden as a result of injuries and to the emergency ward at Umea University hospital (NUS) about 12 000 injured arrive every year. This study is a retrospective cross-sectional study that surveys injuries caused by crashes among 153 pedestrians and 53 bicyclists, who have been injured in a geographically well defined area during the period January to June 2009. The aim of this study is to survey injuries among pedestrians and cyclists and to examine what preventive measures could reduce these injuries in the Umeå municipality. The results show that falls caused by slipper surface are common among both pedestrians (71 %; n = 109) and bicyclists (32 %; n = 17). Almost one third of the pedestrians (34 %; n = 43) were in the age of 65 or older.

Music has always been an important form of communication and it can be found in many different contexts including aesthetical, cultural and emotional forms. In the globalized society of today music can be distributed fast through radio, TV, CD: s and the Internet. For many people consumption of music is an important part of the daily life and it can contribute to shape an individual?s attitudes and personality.The main purpose of this study is to find out whether there are any differences between men and women?s musical preferences. I will apply an explorative approach using qualitative interviews to describe what causes the differences.

An energy calculation model for Swedish houses   that is fast, flexible and user-friendly has been developed within the   framework of this thesis.  The model   also provides a set of actions which may be investigated in the model based   on savings and payback period. Energy use in a house depends on the technical   conditions, such as building envelope and heating systems, which outdoor   climate the house is exposed to and who lives in the house. Energy use for a   house can be divided into heating, hot water and household electricity. There   are several methods to calculate the energy use of a house. This report   summarizes the methods that may be suitable for a fast and user-friendly   calculation model.

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept which is far more complicated than measuring how much built surface that needs to be covered. It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.
