When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

Allteftersom forskningen inom Human Computer interaction (HCI) fortskrider konstrueras det allt fler innovativa sätt att interagera med spelkonsoller. Då fler sätt att interagera med spelkonsoller utvecklas förbättras även förutsättningarna för spelbranschen att öka interaktionen i spelen. Den senaste generationen av spelkonsoller har kommit fram med egna lösningar och innovativa sätt att öka spelupplevelsen och interaktionen. Nintendo Wii har t.ex. en rörelsesensor som reagerar på rörelserna av handkontrollen, och Xbox Kinect reagerar med hjälp av en kamera som läser av kroppens rörelser och Playstation Move reagerar på en kombination av en kamera och en kontroll med sensorer. Handkontrollens design har inte förändrats mycket under de senaste konsol-generationerna om man bortser från Nintendo Wii som formade sin kontroll som en stav.

The use of laptops, interactive whiteboards and the Internet is step-by-step working it?s way into Swedish schools. The aim of this study is to investigate the attitudes of teachers towards using IT-related tools in their teaching. How are the tools given used as mediating tools, what new methods do the teachers find themselves discovering while using these, how do the teachers feel about digital teaching platforms and how do the IT-related tools affect students language progression? These are all questions that this study is meant to answer.

In several cases, systems that have been developed have been very time consuming and cost a lot of money, but they still do not fulfil the users requirements and requests. To make new systems better, you have to find a way to communicate that allows the developers to understand the needs of the user. The aim for our thesis is to highlight the importance of communication in system development. To investigate this we have choosen to do a study of the real-estate system. The work methods that have been used include mock-ups and informal conversations with the user, who is employed by the Church of Sweden in Ronneby.

Drink! The Marketing History of The Coca-Cola Company: A Modernization Perspective examines the development of The Coca-Cola Company?s marketing history, from the founding of the company in 1886 until today. The Coca-Cola Company has been superior on the market for over a century. It has also developed along with the urbanisation of its society, which is interesting in a modernization perspective. The essay investigates the marketing strategies of the company, with focus on three themes: gender, sponsorship and interactive culture phenomenon.

In this paper an upper level compulsory school is examined from a gender perspective. The purpose of the paper is to analyse how girls and boys acquire space in the classroom (during a Swedish lesson) and in the sports hall (during a lesson in physical education). To fullfil the purpose of this paper a seventh grade class was observed during a lesson in Swedish as well as in sports. In addition to this on pupil was interviewed. In this paper the results are compared to and measured against results from earlier research in the field. Used as a theoretical basis are Simone de Beauvoir?s theories on gender.The results attained indicate that girls and boys claims space in different ways during time in the classroom as well as in the sports hall.

This study?s aim was to explore how the social media Twitter is used by Swedish political leaders and how they manage the relationship between having both private and public conversations in a new public sphere, the social sphere. In Sweden, studies in this area are yet to grow. We achieved our aim by responding to our three questions at the issue: What kind of content is published in each of the politicians Twitter stream? Are the politicians private or public persons on Twitter? Are the politicians using Twitters interactive functions? We conducted our analysis by performing a quantitative content analysis.

This paper briefly summarizes Bergslagen as a bedrock province in order to give background to the genesis and presence of REE-bearing minerals (short for Rare Earth Elements) in the region. These mineralizations mainly occur along the REE-line, a line aproximately a hundred kilometers in length between Norberg in the north and Nora in the south with a width of a few kilometers. Situated in the southwest of Bergslagen it is currently one of only a few places in Sweden where REE-bearing iron oxide mineralizations are potentially economically viable for mining. Ore microscopy has been conducted in order to characterize an ore sample from Myrbacksfältet, one of few sulphide rich iron oxide mineralizations within the REE-line. Additionally, an electron microscope analysis of a sample from Stålklockan, a suspected REE-bearing mineralization also within the REE-line was confirmed by EDS (short for Energy Dispersive Spectrum) analysis.

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security. In order to study usability, a test group of ten persons have been used to evaluate the usability of the system.

Syftet med detta kandidatarbete var att sätta samman ett promopaket bestående av en webbsida och en demo-EP med passande grafisk design. EP:n har tre spår elektroakustisk instrumentalmusik av skiftande karaktär, samt ett stilrent men ändå suggestivt omslag. Webbsidan är till för att presentera mig själv och mitt arbete (inte bara musik), och är byggd med hjälp av HTML, PHP, CSS och MySQL..

Our bachelor thesis is a visualisation made in 3D-graphics of how the horserace track in Tingsryd perhaps will look like in the future, complete with a miletrack, steeplechase, and other horserace courses. Today, the race track is only in it?s building phase. The inner field-group in Tingsryd needed presentation material to show their eventual sponsors, so they contacted us at Media Technology, and we instantly decided to give their idea a try..

Efter fyra månader som ljudpraktikant på det svenska spelföretaget Starbreeze i Uppsala, var det dags att ta steget vidare i ytterligare fyra månader. Från ljuddesign till scriptning, idéer och tankar, samt en inblick i hur scriptning fungerar. Detta arbete handlar om framtagandet av en ljuddesign-prototyp åt ett externt företags framtida spelprojekt. En utveckling som från början var tänkt att öka kunskaperna om scriptning, och att skapa ett sammanhängande spelscenario, men som sedan utvecklades till att leda mycket längre. Förklaring: Ljuddesign = Ljudläggning av någon form, i detta fall spel.

The goal of this thesis is to investigate the W3C Geolocation API from a developer?s perspective, focused on whether it makes development of location-based applications more accessible to developers. This has been investigated by looking at available ways to locate, possible uses, the functionality offered, the necessary level of prior knowledge needed for a developer and requirements on developer tools. This has been achieved through studies in relevant areas, a thorough introduction to W3C Geolocation API functionality, and by using the API to develop two different location-based applications as a demonstration. Testing of applications, on different platforms and in different environments, in conjunction with investigation of the rest of the material has shown that W3C Geolocation API in many ways actually makes development of location-based applications more accessible for developers. The API also provides fully adequate functionality and quality to meet the requirements for development of both simple and very advanced location-based applications. Målet med denna uppsats är att undersöka W3C Geolocation API ur ett utvecklarperspektiv, fokuserat på om den gör utveckling av positionsbaserade applikationer mer tillgänglig för utvecklare.

This study has examined how social media has changed food companies way of holding contests. The study examines how food companies use contests with the help of social media and how they used to do the contests before the use of social media. We have also researched the users behaviours and opinions of companies contests on and outside of social media.In this study we have interviewed four people responsible for contests on the social media department on their respective food company. We also performed a survey that was published on Facebook and followed it up with interviews from two of the participants.This study has showed that contests on social media, as a technical aspect, have given new possibilities for the design of the contests. But there are still some unexplored areas around contests on Facebook and the companies do not know exactly what the users are demanding.
