More and more people in our society take part in adult education. In this study, eight students in adult education, the majority with a diagnosis such as ADHD and/or reading- and writing disorders/dyslexia,have been interviewed about their current study situation. The interviews have so party treated topics related to earlier schooling and the future. Earlier studies and available literature is to a large extent written from the perspective of children?s and adolescents? study situation and the question is if this is applicable to students in adult education.

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

The aim of this thesis project is to produce an algorithm for finding a topologicalrepresentation of a polygon, called a straight skeleton, using floating pointarithmetic. Various straight skeleton algorithms are examined and discussed witha focus on time complexity and one is chosen for implementation. This implementationis then compared with the open source library CGAL with regards torunning time. The result is an algorithm which is based on an algorithm by Felkeland Obdrzalek and which, for polygons with more than five thousand vertices andthree significant digits representing points, runs around 25% faster than CGALsimplementation. Complications regarding the use of floating-point arithmetic arealso discussed..

Today, a large proportion of wood supplied for the Swedish forest industry is bought from private forest owners while forest companies at the same time provide the forest owners with services such as logging services and transportation. Today, forest companies work extensively with keeping the time used for transport and logging short. But what does the private forest owners think about the time required for the timber deal, also called lead time, and the different parts of the timber deal. In this thesis, the forest owners? perception of the different lead times in their contracts with Stora Enso and their communication with the purchasers is examined.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Att skriva enhetstester är en viktig del i nya populära systemutvecklingsmetoder som extreme programming. Med testdriven utveckling skriver man testerna innan den källkod som skall testas. Ett vanligt problem med dessa tester är att de blir beroende av delar i systemet som inte är intressant för själva testen. Mock objekt är en teknik som gör det enkelt att isolera tester från allt som inte är relaterat till det som skall testas.Det finns två sätt att se på mock objekt. Den traditionella synen är att mock objekt skall användas som ett verktyg vid isolering av externa system.

One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands. The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.

This study aimed to investigate written and oral narrative in adults. The participants consisted of 30 subjects aged 32-79 years. They produced one picture elicited and one free narrative, both written and orally. The written narratives were recorded in a keystroke logging program and the oral narratives were transcribed orthographically. Data from all the narratives were analyzed according to: number of words, words/minute, active writing time, total process time, number of characters and number of characters in the final text.

Purpose/Aim: The purpose of this thesis is to study the interaction between seller and buyer in a mobile phone store. The specific research questions under investigation are:Are there any underlying factors behind mobile purchase, and if so, what are they? Are mobile purchases driven by lifestyle factors and do customers try and create identities when purchasing new mobile phones?Material/Method: The study employs an ethnographic method when trying to answer the posed research questions. I have under a period of two weeks studied the seller-buyer interaction in a mobile phone store. In order to further increase the accuracy of my findings, I have complemented my observations with a sample of buyer and seller interviews.Main results: The observations and interviews were initially studied in isolation, resulting in different themes.

Titel: Den osminkade sanningen - En lönsamhetsanalys av en sminkavdelning idagligvaruhandelnBakgrund och problem: Svinn i detaljhandeln innebär problem för lönsamheten idetaljhandelns organisationer. Om en fullständig kostnadskalkyl görs på en avdelning idetaljhandeln som idag är lönsam, framstår avdelningen därefter fortfarande som lönsam?Syfte: Syftet med studien är att, med hjälp av en kalkyl, göra en analys på lönsamheten på ensminkavdelning i en dagligvarubutik, samt att jämföra detta resultat med liknande underlagfrån en jämförbar butik. Vidare syftar studien till att om möjligt ge förslag till förändring samtatt utöka det empiriska underlaget kring kalkylering inom svenska organisationer.Metod: Undersökningen har genomförts med hjälp av kvalitativa metoder såsom intervjueroch bearbetning av insamlad data.Resultat och slutsatser: Butikerna i studien visade varierande lönsamhet, såväl positiv somnegativ beroende på hur beräkningarna genomförs. Denna lönsamhet skiljde sig från vadbutikerna enligt sina metoder beräknade.Förslag till vidare forskning: Utförande av en liknande studie, fast på en annan avdelningsåsom en charkavdelning eller fruktavdelning.

The visual complexity in real-time applications, like computer games, is increasing with customer demands on vissual apperance. This trend is supported by even better graphics cards from the hardvare industry. This must be taken into consideration when the architecture of a new graphics engine is to be designed. The engines renderer is responsible of generating a picture of scene data. The renderer must cope with increasingly more complex scenes, and must be able to render them depending on available hardvare capasity.

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.
