Den amerikanske flygvapenöversten John A Warden III har lagt fram en teori om att man kan se på fienden som ett system av system för att hitta hans svagheter. Teorin bygger på att skapa en bild av fienden genom en fördefinierad indelning i subsystem bestående av fem ringar. Denna bild skall därefter kunna brytas ner i ytterligare subsystem bestående av samma fem ringar som till slut avslöjar fiendens tyngdpunkter. Uppsatsen prövar om Wardens teori går att applicera på Al-Qaida..

Sammanfattning Projektarbetet syftar till ett åtgärdsprogram för brandskyddet på SSAB- tunnplåts gamla fartygsmanufakturbyggnad i Luleå. De resulterade brandskyddsförslagen fastställdes genom riskidentifieringar och undersökningar av lokalens verksamheter. Analyser utfördes på de valda riskobjekten samt bearbetades med ett flertal metoder. Rapportens huvudsakliga beslutsstöd är ett datorbaserat simuleringsprogram, Fire Dynamics Simulator. Programmet genomför bland annat beräkningar på brand- och rökgasspridning, effektutveckling och temperatur i lokalens brandceller, på dess material och fordon.

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 this study is to examine how four educators in two different departments at two different preschools in Stockholm, selects children's literature in preschool and how literature is used in the activities and how much influence children have in the choice of literature. Based on qualitative interviews as a method we have interviewed pedagogues to get answers to our questions. We will also interview some children to find out how involved they are in the purchase of literature on the departments we examined. We consider the social cultural perspective to be a well rounded starting point for our survey, because the theory gives us the opportunity to study how the interaction and meetings between educators and children develop for each reading encounter. And through the analysis a thorough display between educators and children towards literature will be shown.

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).

 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 aim of this masters thesis is to examine the supply of magazines and periodicals for young people at the library. We also examine young peoples reading of magazines and periodicals and compare the librarys selection with what young people read. The main questions of this thesis are: What do young people do at the library on their spare time? What weekly magazines and periodicals do young people read? What range of magazines and periodicals do the city- and the school library have? Where is the department located and how is it designed? What kind of relationship is there between young peoples reading and the selection? To answer these questions we have done an interview with a librarian and a questionnaire among 13-16 year old children. We found that it is not often that young people read their magazines and periodicals at the library.

This study is about inmates, who reflect upon their time in school, their experiences of school and how different things have influenced and affect them later in life. The aim with this study is to examine how different kinds of school related issues have affected the inmates in different ways. The aim is also to look at how school can spot in early years, children within the danger zone and provide for those children, so that they can be helped in different ways and so that they can be able to achieve different in life, not to end up becoming criminals later in life.The main questions in this study are:How did the chosen inmates experience their time in school?Can you by looking at research tell that these persons already in their childhood were children within the danger zone?What kind of school related issues could have contributed to a criminal lifestyle later in life?The result of this study shows that all five have been children within the danger zone. In all five cases there have been school related issues that have affected those men.

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.
