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!.

Hälsoeffekter från trafikbuller vid Bäckegatan

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 hjälp 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 utvärdering 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.

Utvärdering av arkitektur för underhåll av ett Back Office-system

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..

Optimerad signal av omgivningstemperatur på tunga fordon

SammanfattningScanias lastbilar har under de senaste åren haft en snabb utveckling när det gäller elektronik och styr - reglerteknik. En givare som inte har haft samma utveckling är yttertemperaturgivaren som introducerades i Scanias lastbilar 1987. Totalt finns det idag 10 olika ECU-system som använder sig av givarsignalen. Det har visat sig att yttertemperaturgivaren i Scanias lastbilar visar för högt värde i vissa körfall. Stora avvikelser på yttertemperaturvärdet har inte varit ovanliga när motorn har varit varm och lastbilen färdats i hastigheter under 30 km/h eller kör på tomgång, till exempel vid ett rödljus.

ASB lika med SAB? En jämförelse av dokumenttitlar i de båda 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 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.

Tekniska och sociala faktorers inverkan på relationer i affärsnätverk - En kavalitativ studie av ett producerande företag

Bakgrund: Relationer har en central roll vid byggandet av företagsnätverk. Rapporten delar upp relationerna i tekniska och sociala relationer. Påverkan av tekniska system eller andra tekniska lösningar är tydlig och viktig att arbeta med för att uppnå en långsiktig affärsrelation. I rapporten undersöks hur tekniska lösningar påverkar de sociala faktorerna i en B2B relation. Fallföretagets perspektiv tas som utgångspunkt i rapporten och hur relationer med befintliga återförsäljare inom deras affärsnätverk påverkas av olika tekniska system.

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 värmebehov för kombinerad kontors- och laboratoriebyggnad utan traditionellt värmesystem

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 väg genom en romersk stad. -Från 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..

Prestationsmått: Ett verktyg för styrning - eller en rapport bland alla andra. Om mellanchefers tillämpning av prestationsmått 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.

Replikering av komplexa kunskapssystem : En fråga om organisatorisk integration

Background: Many authors consider knowledge to be a significant source for competitive advantage. Replicating companies found their competitiveness on an ability to leverage its knowledge base by replicating its business model in new contexts, a process often referred to as the McDonalds approach. Several authors emphasize that an efficient method for knowledge transfer may increase the risk for imitation. Purpose: The purpose of this study is to examine in an explorative manner how strategies for replicating complex knowledge systems are employed and developed. Furthermore, our ambition is to explore the notion of replication strategy.

Bilden av kvinnan i Library of Congress Classification En genusstudie av Library of Congress Classifications första och senaste upplaga

I have done a comparative gender study of Library of Congress Classification from 1900 and 2001. I have also used a hermeneutic method and ideological critics to find out what picture of women the both systems shows. In my comparative study of the both systems I have found low update of classes which relates to women in the new classification system. Men seem to be a norm in the system, because men are not defined in classes related to both men and women. But many classes related to women are named Women as and Women in The study also shows that women are more related to subjects about family and marriage than men are.
