Sammanfattning Idag finns många interaktiva tjänster, till exempel publika webbtjänster. Dessa tjänster väljer användaren själv om han/hon vill använda sig av. Detta betyder att produkten bör vara enkel och behaglig att använda, annars tappar man användare och eventuella kunder. Det finns ett flertal teorier och guidelines för hur man gör en webbplats användbar. I denna rapport har vi valt att behandla de teorier som rör navigering och informationsstruktur och jämför dessa med Blekinge Tekniska Högskolas webbplats.

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

För att ta reda på hur väl en Multi-Agent-Systems-bot kan stå sig mot andra, icke-MAS-bottar, så har vi implementerat en bot till brädspelet Arimaa. Botten är implementerad i C++ och den kan spela mot andra bottar, eller människor, genom Arimaas officiella hemsida. Syftet har varit att skapa en fullfjädrad bot som både klarar av att spela korrekt, och att spela bra. För att ta reda på om MAS är en bra designfilosofi för Arimaa så har vi utmanat ett antal av de bottar som andra människor skapat och lagt upp på hemsidan. Alla bottarna har under tiden de legat uppe blivit rankade genom tävlingar och utmaningar och flera av dessa har tävlat om stora pengar, vilket betyder att människor har lagt mycket tid på dem.

For many years, there has been a housing shortage in Sweden. Many have been expecting a construction boom in the housing sector, but that has yet to arrive. With the current legislations and guidelines surrounding modern, energy efficient housing; production costs have increased dramatically in recent years. As a result, having a negative effect on housing production despite the high demand for homes.This exam work is carried out on a construction project of Sjötorpshus AB and its purpose is to evaluate how to optimise the construction process for the production of a new residential settlement, "Kv.Hunden", located in Katrineholm. In an interview with the company's MD, Pär Knutsson, four main issues were defined to focus on.

The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.

NMD 100 is a notes and media dispensing machine, manufactured by De La Rue Ltd, located in Flen, Sweden. The customers, mainly bank offices, have expressed a need for a more comprehensive description of errors occurring from time to time in their machines. In order to acquire a BSc-degree in Computer and Electronics Technology at the University of Linköping I have carried out a diploma work, regarding new computer programs to fulfil the customers? wishes. The machine NMD 100 is connected to its PC through handshaking.

In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.

Tårsubstitut används mycket bland linsbärare och personer med torra ögon. Detär vanligt nuförtiden att arbete i kontorsmiljö och vid datorer ger problem medtorra ögon, Computer vision syndrome (CVS), och att dessa personer dåanvänder tårsubstitut. Ofta står det i tårsubstitutens bipacksedel att de kan geproblem med dimsyn en stund efter applicering.Tidigare studier har visat att aberrationerna i ögat ökar vid applicering avtårsubstitut och möjligtvis är det anledningen till att dimsynen uppkommer.Syfte: Syftet med studien är att ta reda på hur mycket synkvaliteten påverkas avtvå olika tårsubstitut och hur lång tid den påverkas.Metod: Metoden innebar att närvisus och aberrationer mättes på 30 patienter (60ögon) först utan tårsubstitut. Sedan applicerades det första tårsubstitutet(Systane) i höger öga och ytterligare en mätning av närvisus och aberrationerutfördes. Därefter gjordes ytterligare 5 mätningar av aberrationerna, en var fjärdeminut.

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.

Abstract Svanvik, Robin (2013). Läs: spela! En jämförande studie av elevers uppfattningar om datorspel, skönlitteratur och lärande. Svanvik, Robin (2013). It Reads: Play! A comparative study of students' beliefs about computer games, fiction reading and learning. This essay is part of a masters degree of pedagogy and investigates the experiences of 10 high-school students concerning playing computer-games-off-the-shelf (COTS) on the one hand, and reading fictional, printed novels on the other. The aim of this study was to learn more about the students' thoughts about playing COTS and reading novels; also, what differences and similarities there might be between these activities. Furthermore, I wanted to know what they thought they might learn from these activities. The theoretical point of departure for the study is twofold: Firstly, a theory of learning as expressed by Illeris (2007) and, secondly, a sociocultural perspective on learning, represented by Säljö (2000, 2005/2010) which includes the educational benifit of both playing COTS, represented by Gee (2007), and reading fiction, represented by Probst (1990) and Langer (1995). The method used in this study is mainly qualitative by nature.

Internet is the future and VoIP (Voice over Internet Protocol) is growing in use. Companies are starting to realise the benefits with VoIP. Skype is the number one soft phone on the market but it doesn't satisfy the needs of companies (e.g. transfer calls, redirects calls and so forth) and leaves therefore a gap. The purpose of this master thesis is to provide Objektor AB (thesis initiator) with tips on how to design a usable soft phone that they know is based on relevant human computer interaction research.The method used in the thesis has been iterative development.

Costs of maintenance on agriculture machines is something that many farmers has a low knowledge of, it can depend on low interest or that the farmer don?t have enough time. To make it easier for the farmers they can use many computer programs which are available on the market. In this program they can calculate their costs of maintaince on their agriculture machines, for example STANK and JTI machine calculation program. Most of this program is using Svensson (1987) costs model whish was made in Sweden in the middle of 80 decade in a large study.

AbstractEmilia Rönnberg.Barriers to physical activity in adolescents in their late teens. Vetenskaplig C- uppsats HT 12 Physical activity has been essential to human health and well-being since several thousand years. In Sweden, it has been shown that both adults and young people are less physically active than the rest of Europe- a large proportion of young people today do not meet the recommendations for physical activity (60 minutes per day). The purpose of this study was to determine what proportion of young people, i.e. high school students, did not meet the recommendations for physical activity.
