This master of science thesis is focusing on how the fault handling on hardware connected toa control unit on a Scania vehicle is working. To the hardware counts buttons levers, sensorsand CAN. The work has been concentrated upon how the fault handling is working and if it ispossible to find any new fault modes.The control unit that has been studied is called the Coordinator and is the core in Scanias threenetworks of control units. The Coordinators work is to transmit messages between the threenetworks and to process signals from buttons, levers and sensors. The values is then usedinternally or is sent to other control units on the CAN networks.

Since the spring 2003 the tenant-owner home association the Terrace in Upplands Väsby municipality lies straight under the approach route to Arlanda Airport?s new third landing chute. Noise levels of over 70 dB have been measured in the area, which exceeds National Board of Housing?s, values for traffic noise at a terrace in connection to housing. By using the method of hedonisk pricing the essay tries to find out if there exists a willingness to pay to reduce the noise in the area.

Syftet med uppsatsen är att utvidga kunskapen om generella resmotiv hos äldre turister på besök i Stockholm. Detta för att bidra med kunskap som kan förbättra produkterna för och marknadsföringen mot denna målgrupp.Äldre turister är en intressant grupp att undersöka då de ofta behandlas utifrån stereotypa uppfattningar och antaganden om likhet. Gruppen är dock på inget sätt homogen. För att förstå gruppen bättre är det nödvändigt att använda sig av undersegment. Undersökningen intresserar sig för om det är fruktbart att göra undersegmenteringar med hjälp av variablerna resvana och livssituation.

Stålindustrin förser såväl människor som samhället med många nödvändiga byggstenar. I Sverige finns tolv ståltillverkande anläggningar och hela 80 % av stålet exporteras. Som alla andra tillverkande industrier har den flera miljöaspekter att ta hänsyn till, men stålets nytta väger tungt och därför är det av stor vikt att genom forskningsprojektet Stålkretsloppet nå hållbar utveckling. Miljöskyddslagen, miljöbalken och ett ökande miljöengagemang har lett till arbete med miljöfrågor. Syftet med den här studien var att undersöka hur allmänhetens riskperception, attityd och oro gentemot stålindustrin ser ut.

This study examines use and users of information and records originating in the context of a contemporary police organisation. This area of research has only been of focus for a relatively few researchers. This in contrast to use and users of historical archives which has been in centre for more studies. The study is conducted with a quantitative method structuring data from 120 selected registered matters containing user queries. The research questions addressed are:- what user categories use the records of the authority- which are the ways of contacting the authority preferred by the users- which are the identifiers provided by the users and how well are they matched by the search artefacts available to the staff of the authority- what information and records are sought-after by the users.For comparing the identifiers provided to the search artefacts has been selected the two most frequently used registry systems within the authority.

The primary purpose of this paper is to find the determinants of first-day returns on the Stockholm Stock Exchange. Our research will cover the 1996 ? 2004 periods. Our secondary purpose is intended to find a profitable trading strategy with regard to future IPOs on the Stockholm Stock Exchange. By using regression analysis, focusing on company specific factors and the IPO process, we hope to find a function exhibiting statistical significance, determining future first-day returns from which construction of a profitable trading strategy will be possible.

Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.

This paper aims to analyze the effect of the American Subprime crisis of 2007 through the perspective ofHaynes Minsky?s model according to Charles Kindleberger. The investigation revolves how the anatomyof a financial crisis develops and how it is applicable to the Subprime crisis. More specific conclusionsare derived from applying Minsky?s model to the three largest American indices; Dow Jones industrialaverage, S&P500 and NASDAQ.To deepen the analysis the Case-Shiller home price indices acts as a second parameter tocompliment Minsky?s perspective with Robert J.

Energifrågor och energieffektivisering blir alltmer uppmärksammat i dagens samhälle. Kostnadssituationen för energi är idag helt annorlunda mot vad den var för 30 år sen, priset är numera mycket högre. Speciellt påverkar detta gamla sjukhus där det är installationstätt och det finns aktivitet som pågår i stort sett dygnet runt. Här finns det helt klart en hel del pengar att spara in, frågan är bara var och hur? Detta examensarbete innehåller en energikartläggning av kirurgibyggnaden på Universitetssjukhuset i Malmö, i rapporten ofta benämnd som byggnad 33, samt även en fördjupning kring området ventilation avsedd för operationssalar. Rapporten redovisar inledningsvis en energibalans av byggnaden som har åstadkommits med hjälp av simuleringsprogram, uppmätta värden och beräkningar.

Cultivable land is a limited resource and agriculture contributes to some of the most serious environmental problems facing the planet like, global warming, eutrophication and loss of biodiversity. The specialized, industrial agriculture with monoculture and extensive input of external energy, commercial fertilizer, and chemical pesticides are all essentially unsustainable. An adaptation to other methods of production is necessary to preserve the environment for future generations. The aim of this study is to describe the factors that distinguish sustainable from unsustainable agriculture. The results will be used to examine if and how the European Union (EU) works in order to create a more sustainable agricultural industry and to analyze the preconditions for such development.

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.

Lepidosaphes ulmi ? kommasköldlusen har dykt upp som skadegörare i svenska äppelodlingar de senaste åren. Svenska äppelodlare har efterfrågat mer information kring kommasköldlusen och dess naturliga fiender, och därför gjordes denna litteraturstudie. Kommasköldlusen är en pansarsköldlus med ett hårt skyddande skal. Även äggen läggs under skalet och de är därför svåra att bekämpa.

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.
