This study is about the potential advantages as an investment option in a portfolio. The study shows that the incorporation of bitcoins in a portfolio, even to a small degree, gives significant increases of both risk and return. The different studied portfolios sharpe ratio rises, which in turn shows that the risk reducing return increases when bitcoins is used as an investment option.This study is based on Virtual Currency, Tangible Return: Portfolio Diversification with Bitcoins by Brière, Oosterlinck and Szafarz. The authors of this study have compared their own results with the study mentioned and seen its similarities and differences. The study investigated a total of eleven different assets percentage return over 192 weeks ranging from July 2010 to March 2014.

Millions of animals are annually affected by human activities; in the food industry, zoos and animal shows, clothes and shoes production, furniture and pharmaceutical industry, research, as well as pet and sports animal industry. Companies working with Corporate Social Responsibility, CSR, have become more common and within this area there are great possibilities for companies to work with animal welfare. In this study five companies were interviewed and 27 companies participated in a survey regarding CSR and animal welfare. The aim of this study was to investigate opinion and approach among companies towards implementing animal welfare as a part of their work with CSR. Furthermore the aim of the study was to investigate how companies may implement animal welfare. The result showed that the vast majority of the companies participating in the study works with CSR and the main part of the companies also answered that they have implemented animal welfare. The way of working with animal welfare varied among the participants; e.g.

SWITCH- Swedish Intelligibility test for children, is a test thatmeasures intelligibility of children's speech through repetition of singlewords. The test is computer generated and consists of 1000 word listsrandomly selected for each assessment. The purpose of this study was toexamine the equivalence, reliability and validity in the word lists. Word listswere tested on ten children with typical language development (N group)and ten children with speech deviation (T group). The children were audiorecorded when they repeated two lists.

Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.

Det är uppenbart att narrativ används i spel, inte minst i offline-RPG:n (ORPG:n), där berättelserna är vad som står i centrum. Samtidigt som dessa är ett välkomnatfenomen har de också en tendens att passivisera spelaren och påverka känslan avfrihet. I hur hög grad de gör detta är till viss del subjektivt och därför är det av viktvad som motiverar ORPG-spelaren till spelandet. Denna studie har utvecklat tvåspelprototyper som baseras på motivationerna immersion respektive prestation föratt påvisa motivationsgruppernas preferenser. Studien har fokuserat på att ta reda påhur stor vikt de båda grupperna lägger på känslan av frihet, och haft som hypotes attkravet är högre hos prestationsmotiverade spelare.

Inom 3D-grafik, visualiseringar, spel och VR finns ett behov av måttriktig modellering. Traditionellt så används CAD-program för att uppnå ett exakt eller precist resultat. Men då CAD-program inte utmatar polygonal geometri så fungerar det inte att använda resultatet direkt i tidigare nämnda kategorier. Denna studie ämnar att underlätta måttriktig polygonal modellering i Autodesk Maya genom ett tillägg i form av ett grafiskt användargränssnitt. Effektiviteten av detta mäts genom tidtagning på modellering av CAD-ritningar i polygoner hos en testgrupp både med och utan tillägget samt en kvalitetskontroll där resultatet jämförs med specifikationen.

ABSTRACTThis project thesis has been written at the request of Mälardalens University, Västerås.The aeronautical engineering students at Mälardalens University and the pupils of Hässlö upper secondary school, all gets the opportunity to perform a computation lab with a real turbojet engine during their study. The goal of the lab from the University is that it should give the students applied experience from the theory part of which has been tought in the course ?Aircraft Engine Technology?.                      The pupils of the Hässlö upper secondary school are performing simpler calculations from the measured values of the equipment. This turbojet engine is located at Hässlö airport in the premises of Hässlö upper seconday school.Since the installation 1989, the engine has lost both thrust and reliability. This makes the theoretical computations made by the students inaccurate.

There is currently an ongoing discussion in Sweden about the need for weather shelter for farm animals being kept outdoors during the winter season. Currently, the national animal welfare legislation requires weather shelter providing the animals? with access to a dry and clean place to rest, but under certain conditions exemptions can be granted. The Swedish Board of Agriculture has put forward a hypothesis that there is a difference between judicial decisions in animal welfare cases dealing with weather shelters, as to whether the animal has shown to be suffering or not. The aim of the study was to highlight any weaknesses or difficulties when assessing animal welfare issues associated to the absence of or design of weather shelters.

This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.

Syftet med denna studie var att få bättre förståelse för hur datoranvändare organiserar filer och att få ökad förståelse för vilka vägar datoranvändare väljer för att komma åt filer i ett datorsystem designat efter skrivbordsmetaforen. Resultatet tolkas utifrån aktivitetsteori och distribuerad kognition samt tidigare forskning. Halvstrukturerade intervjuer gjordes med 18 datoranvändare i den ordinarie arbetsmiljön. Utöver att svara på frågor fick de också visa och förklara hur de organiserat sina filer samt hur de gick tillväga när de använde dem.Resultatet pekar på en betydande ökning i användning av datorns skrivbord jämfört med tidigare studier. Två typer av lagrad information kunde identifieras, temporär och långvarig.

This project is a learning CD-ROM production aimed at first-time parents. It is using both sound and images, moving as well as non-moving. The purpose of the production is to be an interesting alternative to traditional books. We have been looking at similar productions like drivers license educational CD-ROMs and encyclopedias for inspiration and ideas on how to proceed. In order to give the content some dynamics, we've also added the element of 3D-animated sequences. The application is supposed to be run as a simple executable file with flash embedded.

The work with this paper began with a belief that the permission aspect plays acrucial part when it comes to consumers perceptions of marketing through E-mailand SMS - especially when it comes to advertising that is received through a devicethat the consumer has a strong personal relationship with. The questions to beinvestigated was: "How do users of computers and mobile phones feel aboutadvertisement received through E-mail and SMS?" and "In what way does the usersrelationship to the computer or mobile phone affect how they feel about theadvertisement?". The study was based on a questionnaire as well as an analysis of theresponses in combination with previous research on the subject.The results showed that the majority of the respondents from this papers surveywere found to have a negative attitude toward advertisement through both E-mail andSMS. However, the respondents turned out to have a slightly higher tolerance foradvertisement through E-mail than towards advertisement through SMS.

FPGA-kort är ett bra verktyg för företag som snabbt vill kunna ta fram en prototyp för nya projekt, då de är omprogrammeringsbara så att samma hårdvara kan användas för att göra prototyper till mänger av olika system. Ett vanligt programmeringsspråk för att programmera FPGA-kort är VHDL som är ett hårdvarunära språk. Som ett komplement till VHDL är det väldigt användbart att kunna köra något mer generellt programspråk som till exempel C. Detta går att lösa genom att man använder en NIOS2-kärna i FPGA-kretsen och överför kompilerad C-kod till den från en persondator.Denna rapport kommer att beskriva hur man på ett Altera DE2 FPGA-kort kan implementera olika lösningar för att använda externa gränssnitt till en NIOS2?kärna.

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

Title: Nätdejting för olika åldrar (Netdating for different ages)Author: Henri NekmouchePurpose: The purpose of this study is to investigate what influence the medium Internethas had on building up relationships between people who have dated online, and tocompare two different age groups.Method/Material: In this study the author has conducted personal interviews with sixpeople who all have experienced Internet dating, and had their first contact with agirlfriend/boyfriend online. The questions asked were designed to help answering thepurpose of the study.Main results: This study shows that in general there is a positive view of Internet datingamong both groups. They appreciate the opportunities it provides, as they get to knowthe other persons personality first. Even so, it should be noted that they still tend to be abit ashamed to talk about Internet dating, and some don?t want to be associated with it.The communication pattern tend to be pretty much the same among both groups.
