The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

The aim of the study was to understand professionals? perceptions and experiences of adolescent stress. In the study I interested myself further if you can identify gender-specific patterns in the professional stories about young people's stress and stress related illness. Five interviews were conducted with professionals in psychiatry and social work. The thesis took its incipience in social constructionism.

Mobility Management is about affecting and changing the demand of mobility. It?s not about what traditional planning?s been focused on; to supply for the demand. The demand of mobility is created by us humans since the traffic exists of us. That means that Mobility Management is about changing our needs.

This paper consists of a comprehensive look at the advertising industry as a whole and communication mould various guises in the context of technology development. It also describes a production in the form of a commercial for a network of ten companies called The Lodge. The result is discussed based on questions on the subject communications and marketing. The discussions of this work will then be transferred to a proposal for further research..

The education in Swedish schools today should be for all children. This means that even if a pupil has reading and writing disabilities the education should be in the classroom with the rest of the pupils. The education should include every one.The aim of my study was to investigate the education with pupils that have reading and writing disabilities. I wanted to get a deeper knowledge about working methods that are used for pupils with these problems.In my study I have used qualitative research methods. I have used group interviews and observational studies.

In modern military operations the requirements of transmitting large amounts of information have increased substantially during the last decade. This increases the demand for high-capacity radio networks. It is also very important that military decisions are made on recent and correct information and this implies that low and known delays are required. The existing military radio ommunications, within the Swedish army, do not meet the requirements for capacity and delay. We have investigated how the capacity and average delay can be improved in an Ad Hoc network with STDMA by using antenna arrays.

For the past decades, culture has been given a role as a factor for local and regional development. But what is meant by development and in what ways culture can be of importance in this aspect can be unclear. This thesis examines the perception of the role for local and regional development of one specific cultural place and network ? the cultural cooperative Not Quite in Fengersfors, Sweden. I study the way the role as developer is expressed and interpreted in the discourse of the cultural workers who are members of the network and in the discourse of public cultural policy in the region Västra Götaland and in Åmål municipality.

Studies in the recent years have showed that the preschool playground is important for both the physical and emotional development of children. The Botkyrka local government has decided to improve their preschool playgrounds in order to take advantage of these studies. The administration of childcare and education in Botkyrka is arranging a network between the different preschools where they work together to improve their outdoor environments. The network is arranging workshops and seminars where people from the different preschools can come and gain inspiration for improvements of their own preschools. The administration of properties has created a document where they describe the changes that are supposed to be made to the different outdoor environments. Through the administration of properties and the person who is responsible for the outdoor environments I was introduced to their work with the preschool playgrounds.

Dagens människa är ytterst beroende av webbtjänster och med tiden har det blivit fler och viktigare tjänster som startat upp på internet. Viktiga tjänster som internetbanker. Oftast är det bara ett användarnamn och ett lösenord som krävs för att bli autentiserad så man skulle kunna tro att användarna håller hårt i sina lösenord och att de väljer starka/unika lösenord. För många verkar det dock, enligt källor, vara ett besvär. Borde man ha associeringar för att lätt komma ihåg sitt lösenord eller är det för riskabelt? Det har visat att många tycker om att använda ord som förknippas med webbsidan.

Bakgrund: Alumninätverk är ett nätverk för tidigare anställda på ett företag eller för examinerade studenter från högskola eller universitet. Alumninätverk är ovanligt i Sverige, men i USA jobbar företagen aktivt med detta. I avslutningsskedet av en anställning kommer alumni in som en del i Employer Branding processen då ett företag vill behålla kontakten med sina före detta medarbetare.Syfte: Syftet med föreliggande studie är att få fördjupad kunskap om de för- och nackdelar som företag upplever med att inrätta alumninätverk och vilken effekt det får när ett företag inrättar ett alumninätverk.Metod: För att uppnå syftet med denna uppsats har jag genomfört en kvalitativ undersökning där jag intervjuat ett konsultföretag inom området alumninätverk för att erhålla ett expertutlåtande och fyra företag som idag driver alumninätverk för sina tidigare anställda.Slutsats: Alla företag jag har intervjuat är överens om att fördelarna med ett alumninätverk är många. Bumerangrekryteringsmöjligheten, ambassadörskapet, affärsnätverket och möjligheten att utveckla en kundkontakt i framtiden är fördelarna som främst tas upp. Min slutsats är att fler företag bör börja arbeta med alumninätverk för jag tror att generation Y kräver en strategisk Employer Brandprocess där alumni är en viktig del.

Att maximera sjukhusens och räddningstjänstens täckning av befolkningen är en viktig säkerhetsfråga som diskuteras inom bland annat hälsovårdsplaneringen. Geografiska informationssystem (GIS) kan användas som ett hjälpmedel för att analysera och presentera andelen befolkning som är utanför sjukvårdens täckningsområden och även visa variationer på täckningsområdena när anläggningar slås ihop eller läggs ned. Syftet med arbetet är att presentera en ny, vektorbaserad nätverksanalys i GIS-miljö för att undersöka hur täckningsområdena för räddningstjänsten i Uppsala kommun påverkas.För att utföra nätverksanalysen användes data från Nationella Vägdatabasen (NVDB) över Uppsala kommun. Attributen som användes från NVDB innehöll information om framförallt hastighetsbegränsningar, väghierarki, tid, restriktioner och gatunamn. Täckningsområdena beräknades med ArcGIS och tilläggsprogrammet Network Analyst och resulterade i en översiktlig karta med räddningstjänstens insatstider och även enskilda insatskartor.

The aim of this essay was to investigate how teachers in the preschool class work with literacy. How do they justify the methods used to develop children's literacy abilities? I also wanted to know to what extent teachers enable multimodal approaches within written language practices. My study considers the impact teachers' professional identity has on working methods in the preschool class. I hope this essay will help teachers reflect on their learning approach. I gathered information by interviewing three preschool teachers and one compulsory school teacher for the early years working in three different preschool classes in three different schools.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.
