The purpose of this essay was to determine whether signs as alternative and augmentative communication is one possible resource for children?s language development. Based on my research questions How educators perceive the importance of SAAC as possible resources to enhance children's communication?, For which children is SAAC used? and How does educators perceive child?s best in communicative interactions? have I interviewed six educators in two different kinds of municipalities with different kind of positions.In my background I lift the importance of communication for the human being, what happens to the children who doesn?t get stimulated to their language and child?s best. My literature has shown that children need to have an incentive to acquire a language and that SAAC is mainly created for children with special needs.

Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.

The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.

This thesis investigates how Ericsson AB should do to achieve fast and secure handover when roaming in a WLAN. It also provides a security analysis of the system that the wireless access point is part of. The reason for this is that Ericsson is selling an access point called the ABS 2200 aimed at the public hotspot market. The premise was that they wanted a standardized way of handling the roaming issue. At the outset the 802.11F standard looked like a good alternative (in fact the only standardized alternative).

Copyright is a part of the intellectual property rights. This ancient occurrence became during 19th century observed by the legislation. Great economical interests and values made it necessary to create rules concerning how the exploitation would take place. Several important conventions were created during this century. For example, the Parisconvention (1883) and the Bernconvention (1886).

There are various investments to suit different investors, what affects the investor is the risk he/she takes with the investment and also the awareness  the investor has. According to different theories a higher risk gives even a higher yield to compensate for the extra risk the investor takes.In this paper, we discuss and compare two different forms of savings, Swedish closed-end funds and Swedish mutual funds to examine what alternative that generates highest returns in relation to the risk.To help, we use different evaluation measures that adjusts the different investments risk so that you can compare how well the investments have performed regardless of the risk they have. This will give us an answer about what investment form that have performed the best between 2002.01.01-20010.12.31. Five Sweden mutual funds and five closed-end funds have been selected to participate in the survey.To evaluate this, it is primarily quantitative data, analyzed in the evaluation measures. The results obtained in the survey show that Swedish closed-end funds have performed far better during the selected time period.

The purpose of the present pilot study was to evaluate the parentalintervention ComAlong at the Division of Child Language, for parents ofchildren with severe language impairment. ComAlong is one of the parentalinterventions developed in the AKKTIV project. AKKTIV stands foraugmentative and alternative communication ?early intervention. Thepresent study consists of a case study, a compilation of course evaluationsand an interview with the two leaders of the course.

The Gift 2.0 - A Museological Study of donations of Objects and its Underlying Motives, is a study in order to explain why people choose to donate items for museums, rather than any other alternative.The empirical study consists of qualitative, semi-structured research-interviews conducted with seven selected curators from various museums, with extensive experience of the subject acquisition. I have chosen to only examine Swedish cultural-historical museums. The hypothesis that I assumed was first and foremost that the heritage sphere is what Pierre Bourdieu calls a field. The reason that people would donate objects to museums, is that the donation itself brings cultural capital to the donor, from people with the same habitus. Since I felt that Bourdieus theory of field, capital and habitus could not explain all the reason why people donate items to museum, my second hypotheses was that certain objects are what Annette Weiner called inalienable possessions, objects that at any cost may not be sold or bartered away.

This M.Sc. thesis is a material application evaluation commissioned by the advanced body engineering department at SAAB Automobile AB. The purpose of the thesis is to evaluate implementation of the innovative sandwich design material Hybrix into an automobile body. Today the most commonly material used in the body is galvanized steel sheets and by shifting material to Hybrix several problematic issues have to be dealt with. Hybrix is an innovative sandwich sheet that inherits thin stainless steel face sheets and a stainless steel fibrous core.

Detta examensarbete omfattar produktutvecklingen av en komponent till en mätutrustning som ska mäta flytbarheten hos smält metall.

Arbetet har även utvärderat ett för gjuteribranschen nytt formmaterial som alternativ till dagens gjutsand. Tester har gjorts för att se om återvunnet (material x) går att använda som formmaterial till högtemperaturapplikationer..

The present study concerns a concept development of a product idea that Bengt Magnuson, associate professor, had when a heavy storm caused a widespread power failure of long duration. With a basic power-producing unit one should be able to get through a power loss. The product could also be useful for other tasks if different modules are connected, e g grass mower or snow-blower.According to the product idea the basic unit will be able to produce electric power enough for a fridge, freezer, TV, and a few electric lamps. Normally the basic unit can be used e g as a mower, when such a module is attached. An increased number of tasks would make the contraption useful and tempting for those who do not own an electrical power set in reserve.

This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.

Syftet med detta examensarbete var att undersöka hur lärare använder olika laborativa material i sin matematikundervisning i år 1-3 och hur detta överensstämmer med det sätt som upphovsmännen till materialen avser. Mina frågeställningar har bland annat varit: Vad är laborativa material?, Hur använder lärare laborativa material i matematikundervisningen i år 1-3?. För att söka svar på dessa frågor har jag genomfört en litteraturstudie, och en kvalitativ intervjustudie med åtta lärare som använder laborativa material i sin matematikundervisning. Resultatet visar att det finns skillnader mellan hur lärare använder vissa laborativa material och hur materialens upphovsmän beskriver att materialen ska användas.

Syftet med undersökningen är att undersöka, beskriva och analysera kring hur vida det finns ett bra substitut till bomull. Undersökningen kommer att belysa hur marknaden ser ut i dag och vilka material som används. Vidare utreds parametrarna funktion, kundnytta och hållbarhet, som kan komma att spela roll i valet av material för producenter av yrkeskläder. I dagsläget finns det inget solklart val av material som skulle kunna mäta sig med bomullen gällande de parametrarna som uppsatsen tar upp. Vad man väljer att använda istället för bomull beror mycket på hur företagen väljer att fokusera gällande just funktion, kundnytta och hållbarhet.

The purpose of this study was to examine how teachers act when it comes to play with constructions in preschool. The purpose was also to find out what kind of material the children have to work with and what they do with the things that the children made. The study was based on qualitative semi-structured interviews. Semi-structured interviews was choosen  to get out as much information as possible, with open questions in a semi-structured interview you can get the information that is relevant for the study. The results show that there are different kind of material available in preschool, but knowledge of the subject is missing and demanded by teachers. The material are pretty similar, some of the teachers use material from the forest while others don?t.
