In your Face(book) users! En studie om socialt login och människans strävan efter konsistens

Concern about personal privacy continues to grow among online users along with the fact that new technologies help online companies to share user's private information. Still the usage of online entities such as social networks and e-commerce sites continue to increase. This raises the question of why online users act in such a contradictory and irrational way.Our study examines what impact one recently developed application called social login, which is provided by several social networks and used by millions of online companies, has on consumer's evaluation of online brands when they are primed for various types of information concerning privacy issues. Our assumptions are built up on the theory of cognitive, dissonance and suggest that there will be no differences in evaluation of the brands due to the human need to rationalize their existing behavior and attitudes when they receive new or contradicting information. The potential effects are measured by a manipulation presented in a survey distributed in an online environment to a sample of users (n=,154).

Automobike: en cykel med aktiv balans

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

Ekonomelevers extrajobb under gymnasietiden : Utvecklingsmöjligheter för studie- och yrkesvägledningen

The knowledge of early employment experiences has evolved over the last decade in countries such as Australia and Great Britain. In Sweden, this type of research is still unusual and the aim of this study was to break new ground by highlighting some areas that could be of extra interest in the Swedish early employment research to come. A focus in the study was to give an overview of what job sectors school students work in; and the amount of jobs aquired through school-organized work placement, private social networks or personal marketing of own merits. In addition to this, a multi variate analysis was carried out to find patterns in the picture of early employment experiences among students at upper secondary school. The findings of the study has relevance for ways of conducting career counselling and therefore the general aim of this study is to point out the importance of developing the practises of vocational psychology.A survey among 74 teenaged school students with economics as their main subject has been carried out in a mid-size Swedish city May 2012.

Indoor Positioning Using WLAN

This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.The project was carried on behalf of Sigma, a Swedish software consulting company..
