SmÄskalig elproduktion i urban miljö : Fallstudie av elproducerande system pÄ ett handelscentrum

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 GrÀnby 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.

SAB-systemet och Yahoo! En jÀmförelse rörande traditionell och ny klassifikation

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.

Datorspel som hjÀlpmedel för att förstÄ och hantera komplexa system : Möjligheter, problem, frÄgestÀllningar

Detta arbete tar upp iden om att datorspel kan anvÀndas som ett hjÀlpmedel för att förstÄ och hantera komplexa system, för den enskilde spelaren sÄvÀl som för forskare. Arbetet fokuserar pÄ ett antal kritiska faktorer: möjligheter, problem och frÄgestÀllningar, samt tar upp en diskussion kring möjligheten att se datorspel som vÀrldar, lika verkliga som vÄr egen, dÄ vi ser pÄ det frÄn en position innanför systemet, genom speljaget som en agent i den virtuella vÀrlden, och vilka implikationer detta kan fÄ för hur vi kan lÀra oss att förstÄ och hantera komplexa system.Vi lever i en verklighet i vilken vi omges av komplexa system, bÄde sÄdana vi skapat sjÀlva och sÄdana som finns naturligt. Det Àr en paradox att den teknologiska utvecklingen som strÀvar efter att förenkla vÄr tillvaro ocksÄ undantagslöst komplicerar den. Att försöka hitta nya vÀgar att kunna lÀra oss att förstÄ och hantera dessa komplexa system Àr dÀrför viktigt, och hÀr presenteras datorspelet som ett tÀnkbart redskap för att göra just detta..

Clashes and Education in Timor Leste

The purpose of this qualitative thesis is to describe and analyse the implementation of an education system in the newly independent state, Timor Leste. One question to be discussed is whether an emergency phase is still going on in the development of a functioning school system, or if Timor Leste already reached a capacity building phase? Via the participant's answers in field observations and interviews, the study analyses the clashes between generations, social classes and different levels in relation to the choice of Portuguese as an official language and the international environment in the country. The thesis concludes that a lot of work remains in creating a fully functioning education system. We enjoyed the writing - and hope you will enjoy the reading!.

HÀlsoeffekter frÄn trafikbuller vid BÀckegatan

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.

1553-Simulator. In-/uppspelning av databusstrafik med hjÀlp av FPGA

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).

En utvÀrdering av Peabs inköps- och avropssystem

 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.

UtvÀrdering av arkitektur för underhÄll av ett Back Office-system

Syftet med arbetet har varit att undersöka om en viss arkitektur kan anvÀndas för att underlÀtta utvecklingen av ett Back Office-system till ett befintligt och komplext verksamhetssystem.För att grÀnsa av arbetet och hitta de delar som var intressanta att fokusera pÄ genomfördes intervjuer med tre olika personer som hade olika syn pÄ ett Back Office-system genom sin yrkesroll. Intervjuerna resulterade i ett antal önskemÄl för vad man ville uppnÄ med ett Back Office-system.Arbetet resulterade i en arkitektur som kan anvÀndas för att underlÀtta utvecklingen av ett Back Office-system till det befintliga verksamhetssystemet samt till verksamhetssystemet sjÀlvt. Arkitekturen har utvÀrderats genom att man först stÀllde en mÀngd krav pÄ den och sedan studerade hur den klarade av en mÀngd nya krav som delvis var relaterade till de gamla kraven.Alla tester som gjorts visar pÄ att arkitekturen Àr vÀl designad och lÀtt att underhÄlla samt att den kommer underlÀtta den fortsatta utvecklingen av verksamhetssystemet och dess Back Office-system..

ASB lika med SAB? En jÀmförelse av dokumenttitlar i de bÄda klassifikationssystemen.

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 allmĂ€nna biblioteksförening and in the German ASB system Allgemeine Systematik fĂŒr 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.

Japan & Sverige: En komparation av pensionssystemen

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.

Simulering av vÀrmebehov för kombinerad kontors- och laboratoriebyggnad utan traditionellt vÀrmesystem

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.

Energieffektiv design av ett inbyggt flashminneshanteringssystem

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.

Vattnets vÀg genom en romersk stad. -FrÄn vattenkastellet till mottagaren.

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..

Utbildningens roll för nyttjandet av MPS-system

Tillverkande företag har under de senaste Ären stÀllts inför en förÀndrad marknadssituation, vilket innebÀr att de fÄtt förÀndra sitt arbetssÀtt frÄn en produktionsorienterad syn till en kundorienterad syn. Den kundorienterade synen innebÀr att företag snabbt mÄste kunna stÀlla om sin produktion för att tillfredsstÀlla kundens behov.MPS-system (Material- och ProduktionsStyrningssystem) Àr mycket effektiva hjÀlpmedel vid snabba beslut och omplaneringar, de ger dessutom möjlighet att ge kunder direkt besked om orderstatus. MPS-system tenderar att bli stora och komplexa, de har kontaktytor mot nÀstan alla delar i företagen.MÄnga företag idag köper MPS-system. Stora företag byter gamla förÄldrade system och allt fler smÄ och medelstora företag inför MPS-system. Kommande milleniumskiftet Àr ocksÄ en orsak till att flera företag byter sina MPS-system idag.Med detta vÀcktes intresset för att undersöka om företag som investerar i dyra MPS-system verkligen fÄr ut det de förvÀntar sig av dem.

PrestationsmÄtt: Ett verktyg för styrning - eller en rapport bland alla andra. Om mellanchefers tillÀmpning av prestationsmÄtt i styrningen av operativa enheter.

A performance measurement system can be used as a means to evaluate past performances and to communicate prioritizations. It has also been proposed that a performance measurement system can serve as a method to execute strategies, guide in operational decisions and constitute a tool for making the organization more efficient. Yet one may question if such a system will ever reach this capacity if operating managers do not utilize it as a management tool, but rather treat it as a mere report in the bunch. This paper explores how middle managers in fact apply performance measures and what obstacles there are to integrating them in the management of subunits. Furthermore it serves to investigate whether these managers experience a conflict between how they are expected to use the measures and what they deem possible to adopt.
