The aim with this study is to explore if and how linguistic learning takes places when four pairs ofstudents in grade one writes on the computer. Observations of eight students took place duringtwelve lessons to investigate what happened during their writing processes. This study isimportant because students? computer writing is a relatively new phenomenon in the Swedishprimary school.It is clear that the peer collaboration creates a complex interaction that becomes the platform, andalso the prerequisite, for successful language training. The method can clearly give students profitsin their linguistic development.

Previous research has established coaches' important role in developing elite athletes (Durand, Bush, Thomson & Salmela 1996). Athlete enhancement and assisting athletes achieve ?peak performance? has been a major objective for elite coaches as well as sports scientists (Williams & Kendall, 2007) Despite this common goal, research also question whether sports scientists and the research they pursue really effects coaches knowledge and constitute a foundation for today and tomorrows athletic performances (Bishop 2008).  This study examined elite coaches? needs and use of sport science research as well as the interaction between elite coaches and sport scientists. Following interviews of ten elite coaches, content analysis revealed that sport science is both a formal and informal resource of knowledge for coaches. Development of athletes is seen as the main objective of research retrieval and personal and/or direct contact with the sport scientist is considered to be the best way to assemble.

The aim was to evaluate and suggest improvements for the prototype TIVOLI (sign-learning via computer-based playful interaction). The game purposed to give children who need signing as augmentative and alternative communication enhanced signing skills. Three children in need of signs played TIVOLI at home during 4-5 weeks. Data contained parental interviews, Talking Mats interviews, assessment of signing competence before and after the evaluation period and game protocols. One game interaction per child was filmed.

Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.

This report is on concrete work during the winter and is implemented on Peab?s behalf. The assignment was to describe the differences between a summer- and a winter casting. While it shows the complications that exists, it also show what aids are available, both electronic via computer and physical aids.The information that I have developed is originally from theory in books, information on the internet as well as practical experience from knowledgeable people that works in construction output. Other theories are those I have learned throughout the education to become a construction engineer, including all oral sources over the years.The results I have come up with, I hope will be able to help future construction projects in the planning phase of a winter casting.

Givarna är av typen analoga och binära. Till de analoga givarna hör två stycken temperatur- och en ljusgivare.

Detta kandidatarbete är utarbetat på Blekinge Tekniska Högskola under våren 2002. I utredningen har vi jämfört röstigenkänningsprogram under en treårsperiod, program från 1999 och program från 2002. 1999 års test visade på programvaror med lång träningstid, enkla gränssnitt, stor känslighet för bakgrundsljud och låg användbarhet. Vid arbetsstart förväntade vi oss inte att hitta någon större förändring i användbarheten hos dessa program 2002, då röstigenkänningsprogram inte verkar ha stor användarskara. Utifrån följande hypotes har vi genomfört arbetet: Vi vill med vår undersökning bevisa att användbarheten inom röstigenkänningsteknologi inte har förbättrats under perioden 1999-2002. Vi har för avsikt att med hjälp av test utförda på program och demoversioner bevisa vår hypotes. I enighet med bifogad testspecifikation har vi utfört testerna. Många företag har utvecklat sina produkter och gjort dem bättre.

The main objective of this thesis is to examine the situation concerning information technology, computers and information resources for university students at a selection of universities, and their libraries, in Sweden. Another objective is to compare this situation to what is stated in policy documents on the subject, and if the size of the university matters regarding resources. The thesis starts with a discussion of several authors, Frank Webster, Paul F. Burton and Lars Qvortrup among others, and their views on the information society. These range from whether we are living in it, are in a transition period or are still in the Industrial Society.

Purpose: The objective of this study is to illustrate how participants in leaderless based projects communicate with each other. Several studies have focused on technology-supported projects, such as open source projects, with an established project manager and goal. There is a lack, to the best of our knowledge, in studies that deal with the communication pattern in a leaderless computer supported collaborative project.Method: We have chosen to use a quantitative method where we systematically group several messages according to their content. This method was used in a similar study to illustrate the communication between participants involved in an open source project. We have taken the same Kripendorff based method and adapted it to our study by adding more descriptive variables.Theoretical perspectives: Manuel Castell discusses the aspects of a new communication power that is rooted in the individual as part of a larger creative audience.

In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

AimThe purpose of the study was to investigate how upper secondary school students experience performance demands during their physical education and health classes (PE-classes). The questions were as following: Are there differing perceptions between the sexes whether students experience performance demands? In what situations do the students feel that the demands on their performance are high during PE-classes? Do the students experience of demands on performance differ whether the physical education and health teacher is male or female? Do students feel unfairly treated by the physical education and health teacher during PE-classes?MethodSeven upper secondary schools in Stockholm?s administrative district were randomly selected to participate in the survey. The principals were contacted for further information and to set a date for performing the survey. The project leaders were present during the days the surveys were taken by students in the social science and natural science programs.

Detta kandidatarbete undersöker science fiction, en av de större och vanligast använda genrerna inom medier såsom spel, film och litteratur, genom att studera dess undergrupper, de så kallade subgenrerna. Dessa är specialiserade versioner av genren i fråga och använder den inom vissa förutsatta ramar, exempelvis hur samhället ser ut eller vilken typ av teknologi det huvudsakliga fokuset kretsar runt. Genom att studera hur subgenrer är beskrivna i The Encyclopedia of Science Fiction kan man avgöra att de består av sex punkter: plats, tidsperiod, karaktärer, teknologi, narrativ och visuell estetik. Dessa punkter har använts som ramverk för att utveckla en ny subgenre; Mystech, där scenarier utspelar sig i vad som kan ses som en typisk fantasyvärld med magi och monster, men där dessa egentligen bara är teknologi majoriteten av de påverkade inte förstår sig på. För att demonstrera Mystech har två olika miljöer utvecklats, både i bild och skriven form.

Grafiska dokumentgränssnitt används av de flesta datoranvändare. Det finns i huvudsak tre typer av dokumentgränssnitt; MDI (multiple document interface), SDI (single document interface) och TDI (tabbed document interface). I ena halvan av arbetet har dessa tre analyserats utifrån en rad faktorer med målet att se om någon modells fördelar väger över de andras och om man kan skapa några riktlinjer för när det är bäst att applicera respektive modell när man utvecklar en ny programvara. Analysen är baserad på litteratur samt kvalitativ enkätundersökning och programtest. Andra delen av arbetet har ägnats åt testa om det går att programmera så att slutanvändaren kan välja den modell han eller hon föredrar.
