The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet. The purpose is to give companies a clear view of what it is that influence the consumer into buying theirs products, and how this group responds to different strategies and factors.

The development of five individual pupils? writing abilities, as reported by six of their teachers, is analysed. The thoughts and reflexions inspired by the everyday interaction between the teacher and the pupil suffering from some kind of reading and writing disability are presented. The purpose is to capture what was unique and characteristic in the measures that triggered a positive response in the pupils. Some of the questions answered in this study are: How does the phenomenon of reading and writing disabilities manifest itself in the classroom, and what are the consequences for the individual pupil of the various pedagogical measures available?One conclusion that may be drawn from this study is that there is no cut-and dried method for working with pupils suffering from reading and writing disabilities.

TitelGod, don't you ever feel like everything we do and everything we've been taught is just toservice the future?1FörfattareTor KindahlKursMK1500: Examensarbete i Medie- och kommunikationsvetenskapTerminVT2011SyfteAtt undersöka vilken typ av mediekunskaper eleven kan utveckla i den svenskagymnasieskolan (Gy2011) och hur detta ska förstås i relation till forskning inom MediaLiteracy samt utbildningsfilosofier och politiska ideologier.Metod och materialECA (Ethnographic content analysis) och styrdokument för gymnasieskolan.HuvudresultatMediekunskaperna handlar mer om att orientera eleven i olika mediekunskapsområden samtgrundläggande färdighetsträning som både gäller hur man använder media och hur medier kananvändas för att sprida budskap - i synnerhet till olika målgrupper. De handlar mindre om attbelysa intressekonflikter, normer och värderingar i samhället. Mediekunskaperna igymnasieskolan är följaktligen en snäv gestaltning av vad som förespråkas inom MediaLiteracy-forskningen. Man kan av samma orsak även konstatera att kunskaperna i hög grad ärinordnat under vad Englund kallar den vetenskapligt rationella utbildningskonceptionen..

The educational underachievement of children in foster care has been known for a long time. This study aimed to compile and analyze the current knowledge about interventions, intended to improve foster children?s school achievements. The method used was a systematically undertaken narrative review. Despite a comprehensive searching strategy, only ten relevant studies were found, indicating that little has been done to improve the educational outcomes for children in public care.

In this essay I have chosen to take a closer look at gold figure foils (Swedish ?guldgubbar?), find their context and analyze it. I have analyzed some earlier studies about gold figure foils that were found in Scandinavia.The focus of my study is based on the locations of the findings. Another important aspect is to discuss if the encountered gold figure foils that were folded and cut looked like that due to intentional motives or not.My conclusion is that when it comes to the locations of the findings they are mostly found in houses irrespective of if it´s in a posthole, wall or house foundation.The other conclusion is that the gold figure foils could have intentionally been manipulated before they ended up in the ground..

Virtual Communities is an increasingly common phenomenon on the Internet. Most of the Virtual Communities are operated and maintained on a non-profit basis with a direction towards entertainment. However, as more state administrated and commercial services become web-based, we believe that the number of Virtual Communities with a community-based or commercial direction will increase in a near future. In this thesis, we describe our participation in, and studies of, a number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?.

This essay represents a chronological and contextual analysis of clay pipes that have been found in the urban settlement of Västergarn during seminary excavations between 2006 ? 2012, conducted by Gotland University. Clay pipes can be dated closely and are useful means for dating and interpreting archaeological contexts from the early modern period, such as house foundations. There have been excavated four house foundations in Västergarn with different sorts of clay pipes dating to the post-medieval period. Can they tell which people used them or which country they were produced? By discussing the meaning of clay pipes in early modern society on Gotland this essay tries to answer these questions..

With inspiration from Bitzers situational analysis a phenomenografic method has been used, influenced by Brown & Levinsons´s theory of politeness, to find perceptions concerning constraints (in Bitzer´s sense in his model of the rhetorical situation) in Internet-based communication. Based on three qualitative interviews, this essay has found that the perceptions are closely linked to views of what constitutes formal and informal contexts, varying due to the gender or age of the informant. Netspeak is not considered appropriate, with some exceptions, in any formal situation. However, the perceptions regarding decorum in informal situations differ in nature, based mainly on what kinds of associations and connotations are produced by elements found in netspeak. Since perceptions regarding informal situations vary, there is a large risk of misunderstanding, which this essay aims to survey..

Syftet med den här studien var att ge en bild av vad som sker i mötet mellan lärare, elever och skönlitterära texter i grundskolans senare år. Jag ville undersöka hur lärarna planerar sina lektioner utifrån skönlitteraturen och kursplanen i svenska och vad som händer under själva processen. För att samla in data använde jag semistrukturerade kvalitativa intervjuer. Jag intervjuade fyra svensklärare på fyra olika grundskolor. Resultatet påvisar att läsning av skönlitterära böcker har en given plats i skolan och att lärarnas främsta syfte är att motivera och inspirera elever till läsning.

The aim with this thesis is to develop a plugin; Lovefish, for the purpose of allowing non-realistic renderings (NPR) for visualisation in Newtek Lightwave3D. The main purpose with Lovefish is to offer textured tones, something that has not been offered before by any previously existing shader for Lightwav3D. The textured tones are a substantially widening of what is possible to imitate in the field of classical art techniques. Among others has a number of SIGGRAPH papers has been the foundation and a source of inspiration for what has been achieve in this project. Further has this thesis treated a number of questions: what is non-photorealistic rendering is and how it works; an overview of the Lightwave3Ds software development kit (SDK)..

Dagens teknologiska utveckling har bidragit till vårt mediaintensiva samhälle som iallt större utsträckning har övergått till ett konsumtionssamhälle. Trots Sverigesrestriktioner gällande marknadsföring riktat till barn, står barn för stora delar avlandets konsumtion, vilket inte minst förstärkts genom internets utveckling. Dagensbarn är rikare än någon annan generation genom tiderna, vilket är något företag i daguppmärksammat vid utformandet av marknadsföring och produkter. Varumärken harfått en större betydelse på den konkurrenssatta marknaden, inte minst bland barn.Uppsatsens syfte är att identifiera och fördjupa diskussionen kring barnskonsumtionsmönster i yngre åldrar. Uppsatsen belyser den varumärkesmedvetenhetsom råder i åldrarna 6-10, samt identifierar likheter respektive skillnader gällandebarns relation till klädmärken.Studiens huvudsakliga teorier är varumärkesvärde, visual literacy och grupptryck,vilka sammankopplas med den insamlade empirin för att svara på hur barns relationtill klädmärken ser ut.

In modern health care, the quality registry is anexcellent tool to monitor everyday work. Collected data forms a foundation, presented as online reports, from which local work efforts to refine care quality can be performed. All reports are coded manually by specially trained developers. This is a tedious process and hence becomes a bottleneck in the strive for improvement.This thesis evaluates whether an extended way of dealing with reports can fit into the existing work situation, with main focus on the idea of creating custom reports directly within a quality registry. It provides a set of conclusions regarding today's usage of reports as well as the users' general and specific needs within the area.

As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..
