During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

The purpose of this quantitative study was to examine the relation between sporting events, where alcohol is served, and the attitude towards alcohol among adolescents. We conducted a survey with 195 respondents, all of whom was students of Swedish upper secondary school. The respondents were between 15 and 18 years of age. The data were analyzed using theories of attitudes and norms. We also analyzed the data using previous research.

In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.

Syftet med examensarbetet har varit att undersöka möjligheterna för ett system till Skogsvårdsstyrelsen Värmland/Örebro, där uppgifter ska registreras i handdator vid fältbesök och därefter verifieras och slutlagras i Skogsvårdsstyrelsens databaser. Under arbetets gång har olika skogsorganisationer och företag intervjuats för att ta reda på om de har någon lösning som skulle kunna passa för Skogsvårdsstyrelsen. De lösningar som används av andra organisationer/företag har analyserats för att få fram för- och nackdelar med de olika varianterna. Slutprodukten innefattar inte någon prototyp på hur uppgiften skulle lösas utan föreslår olika verktyg som skulle kunna användas. Arbetet har grundats på litteraturstudier om införande av GIS i organisationer samt intervjuer och brevkontakt med personer och företag som arbetar med eller har kunskaper om fältGIS.

The aim of this study was to examine care managers and how they understand and use their discretion. We used a qualitative method and the data was gathered by semi-structured interviews. We interviewed eight care managers in four different municipalities in southern Sweden. The theoretical approach we used was Michael Lipsky?s theory about street-level bureaucracy.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

Examensarbetet behandlar matteidrott, vilket är ämnesövergripande undervisning inom skolämnena matematik och idrott och hälsa. Där idrotten ska ses som medlet för att nå fram till målet som är matematiken. Det vill säga att examensarbetet handlar om laborativ matematik med kroppen som konkretiserande verktyg.Syftet med examensarbetet är att försöka ge ett didaktiskt bidrag genom vilket traditionell matematikundervisning möjligen kan utvecklas. Genom genomförandet av en fallstudie ur ett sociokulturellt perspektiv undersöka om elevers referensbilder i matematikområdet geometri kan utvidgas genom den matematik de genomför inom ämnet idrott och hälsa.Undersökningens data samlades in genom ett tillvägagångssätt som benämns som mixed methods i metodlitteratur, vilket bidrar till studiens två infallsvinklar. En med intervju för insamling av kvalitativ data och en med enkät (matematikdiagnoser) för insamling av kvantitativ data.

Background: Funds have become a more popular way for investments. After the financial crisis in 2008 there was some sectors that shown a better results than other depending if the sector was affected by the economic situation or not. Therefore can  investments in sector funds be a good way to get a high return, but it also has a high risk.Problem: Has the risk any impact on the return considered funds in sectors that is affected by the economic situation relatively to sectors that isn?t affected by the situation in the economy?Purpose: Determine whether sector funds risk has any impact on the return. Also if there are any differences between sectors depending if they are affected by the economic situation or not.

The purpose of the study is to analyse the representations of Jewish festivals and how they affect the teaching in three textbooks for Religious Education 1 in Secondary Upper Education. The textbooks are Religion och livet (2007) written by Börge Ring, Religionskunskap för gymnasiet (2009) written by Lars-Göran Alm and Religion 1 för gymnasiet (2012) written by Lennart Göth, Katarina Lycken Rüter and Veronica Wirström. The basis for the study is the phenomenological perspective as described by Émile Durkheim and in particular Carl-Henrik Grenholm and Karl-Johan Illman. It tells that religion cannot purely be understood as a religious belief without its rituals. This phenomenological perspective on religion both the curriculum and syllabus encourages.

This study examines differences between private and state-owned companies' sustainability reports for the year 2010. Three state-owned companies and three private companies in three different industries have been examined. An effort has been put to explaining if differences are related to the owner or to the industry. The basis for this is that the state owned companies are required to present a sustainability report according to shareholder demands, while the private owned aren?t obligated to present their sustainability efforts.The study has a qualitative basis, and empirical data have been collected by the authors.

Methodology: The methodological approach adopted for this work is quantitative; using secondary data from the internal database from the company. The analytical model is tested through statistical analysis using the data?s obtained from the databases.

Syftet med denna studie var att, med hjälp av ett neuropsykologiskt testbatteri, undersöka huruvida kognitionen är påverkad gällande uppmärksamhet och exekutiva funktioner hos patienter som lider av multisystemsjukdomen Dystrofia Myotonika typ 1. Syftet var också att, med hjälp av självskattningsskalor, undersöka hur de drabbade själva uppfattade sin situation i detta avseende. Insamlade data från en patientgrupp bestående av 33 individer med konstaterad Dystrofia Myotonika typ 1 jämfördes med data från en kontrollgrupp bestående av 25 friska individer. Resultatet visade att patientgruppen genomgående presterade sämre än kontrollgruppen på de neuropsykologiska testerna. Resultaten på självskattningsformulären gick i linje med detta, vilket tyder på att patientgruppen, generellt, delvis är medveten om sina kognitiva svårigheter.

Under de senaste åren har det utvecklats en rad nya applikationer på internet, så kallade sociala medier, där användare kan interagera med varandra på ett sätt som tidigare inte varit möjligt. Antalet användare av sociala medier, ökar ständigt och företag börjar inse potentialen att använda dem i sin marknadsföring. Syftet med denna uppsats var att undersöka och förklara hur marknadsföring i sociala medier skiljer sig från traditionell marknadsföring samt hur de olika delarna av sociala medier kan användas i marknadsföringsprocessen. För att kunna göra detta har vi samlat in och studerat både primär och sekundär kvalitativ data. Primär data har vi erhållit genom intervjuer med tre personer som dagligen arbetar med marknadsföring inom sociala medier.
