This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The aim of this Master thesis is to investigate the similarities and differences between a traditional and a new classification scheme. Two classification systems are compared, "The Swedish Library Classification System" the SAB-system - and Yahoo!. The SAB-system has been used in Swedish libraries since the beginning of the 20^th century, and Yahoo! has been online since 1994. Yahoo! has a Swedish version of its international original, which is used in this study to get a similar starting point with the SAB-system. The method used for this is a content analysis, which in this case is not a quantitative analysis.

Detta arbete tar upp iden om att datorspel kan användas som ett hjälpmedel för att förstå och hantera komplexa system, för den enskilde spelaren såväl som för forskare. Arbetet fokuserar på ett antal kritiska faktorer: möjligheter, problem och frågeställningar, samt tar upp en diskussion kring möjligheten att se datorspel som världar, lika verkliga som vår egen, då vi ser på det från en position innanför systemet, genom speljaget som en agent i den virtuella världen, och vilka implikationer detta kan få för hur vi kan lära oss att förstå och hantera komplexa system.Vi lever i en verklighet i vilken vi omges av komplexa system, både sådana vi skapat själva och sådana som finns naturligt. Det är en paradox att den teknologiska utvecklingen som strävar efter att förenkla vår tillvaro också undantagslöst komplicerar den. Att försöka hitta nya vägar att kunna lära oss att förstå och hantera dessa komplexa system är därför viktigt, och här presenteras datorspelet som ett tänkbart redskap för att göra just detta..

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

The aim of this empirical study was to investigate how nurses on a ward within the emergency clinic deal with analgesia prescriptions and the pain management documentation. The used method was divided into chart reviews and qualitative interviews with nurses in clinical practice at the ward. This means that both a qualitative and quantitative approach was desired. The results incline that nurses generally apply to the laws and restrictions surrounding the nursing discipline, as used in pain treatment. Thus they generally fulfill the obligations accounting to documentation.

 This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.

Syftet med arbetet har varit att undersöka om en viss arkitektur kan användas för att underlätta utvecklingen av ett Back Office-system till ett befintligt och komplext verksamhetssystem.För att gränsa av arbetet och hitta de delar som var intressanta att fokusera på genomfördes intervjuer med tre olika personer som hade olika syn på ett Back Office-system genom sin yrkesroll. Intervjuerna resulterade i ett antal önskemål för vad man ville uppnå med ett Back Office-system.Arbetet resulterade i en arkitektur som kan användas för att underlätta utvecklingen av ett Back Office-system till det befintliga verksamhetssystemet samt till verksamhetssystemet självt. Arkitekturen har utvärderats genom att man först ställde en mängd krav på den och sedan studerade hur den klarade av en mängd nya krav som delvis var relaterade till de gamla kraven.Alla tester som gjorts visar på att arkitekturen är väl designad och lätt att underhålla samt att den kommer underlätta den fortsatta utvecklingen av verksamhetssystemet och dess Back Office-system..

The purpose of this Masters thesis is to compare the scheme structure of two national classifications system, namely the Swedish SAB system and the German ASB. It has been assumed that there are no major differences between the two models of classification systems or the main classes into which documents are placed. The classification theory and subject analysis, which form the basic theory on which my research is based, are taken from Dahlberg, Langridge and Rowley. A comparison of 30 monographs classified in the SAB system Sveriges allmänna biblioteksförening and in the German ASB system Allgemeine Systematik für öffentliche Bibliotheken showed that the classification structure was primarily responsible for determining where a particular document was placed. However, despite the fact that the subject in various documents may be similar, my research will demonstrate that the structure of the two codes also depends on different interpretations of the main subject in a document.

The purpose of this essay was to compare the Swedish and the Japanese pension system and see if there were any big differences or similarities. I was looking for answers to such questions as if the systems were modelled with the problematic demographic situation in mind and also how these two countries had tried to manage the problems. Path dependency was also a central conception when I studied the reforms of the two pension systems. I mainly used literature and Internet sources in my study. There were many books on the Swedish pension system and the debates that had been going on since the 80's.

In this paper we have studied possible future uses for Additive Manufacturing (commonly referred to as 3D-printing) in Space. More specifically we have sought to establish how Additive Manufacturing can be used to construct structures on the Moon. Our studies have shown that Additive Manufacturing has great potential for establishing colonies on not only the Moon, but perhaps even further away from our home planet. With Contour Crafting-technology in combination with ISRU (In Situ Resource Utilization) we could, with material already present in the sediment layers of the Moon, construct advanced structures without having to transfer any extra material from Earth. This would lower the costs of establishing a colony on the Moon to such extents that it could actually be fiscally possible..

This report is based upon an experimental study of exit sign luminescence in different environments. The purpose is to evaluate the lowest luminescence of an exit sign, based upon Swedish regulations. Scientific experiments have been conducted in a controlled environment, where exit sign luminescence was graded by an evaluation group. The results of these have been verified by similar experiments that took place in two department stores. The final result of the study is guidelines for appropriate exit sign luminescence in different environments..

In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built.The energy needed for the heating of the building was simulated using VIP+.The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency.

The report is the result of a master thesis at ENEA AB during the fall of 2009. Itaims to create a specification of flash memory management system which focuseson power efficiency and low RAM usage for embedded systems, and to design andimplement a prototype of such a system to facilitate further development toward thecreated specification. The system used by ENEA today is a Flash Translation Layer(FTL). It has a complex structure which prohibits modifications and customization,therefore a new flash memory management system needs to be developed.The suggested solution uses a translation layer called Metadata FTL (MFTL), wherefile system metadata and userdata are separated from each other in order to improveperformance. The partition holding userdata uses a block-level mapped translationlayer system called Fully Associative Sector Translation FTL.

The purpose of this paper is to make an analysis of the urban Roman water system. I have chosen to work with the system as a general field, not as a case study of a single town. In my opinion such a study would not give a proper and fair view of the subject. Therefore, this paper will discuss the different parts of the system, each one for itself and name examples wherever possible, to give a wide survey of the reality of the Roman water supply system. The aim is to give the reader a clear picture of different solutions used in the time of the early Roman Empire and a good understanding of the subject..
