This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters.
Undervattensvågbrytare - En modellstudie
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

GRAVMONUMENTET I HÄLLSTAD: ETT VISUELLT SKÅDESPEL FRÅN 1100-TALET
The aim of this master thesis is to study the reliefs of a Romanesque tombstone from 1130 AD, with the intention to form a plausible understanding of their meaning. During the course of the investigation, my main focus will be on collecting materials of an iconographical and historiographical nature, as they appear in previous studies. I will also use performative analysis when examining the tombstone. Consequently this thesis can be seen as a survey of history and place; early Christian iconology as well as the experience of the viewer. As a result, the 900-year-old tombstone will not only be seen as a memorial in this text, but also as a performance of one man?s faith and as representing the core message of the early Christian church.The tombstone is a rarity in Swedish art history and well worth a closer examination.
Passiv face time - En studie av passiv face time på ett företag med flexibla arbetsförhållanden
The purpose of this study is to examine how employees in an organization using flexible work practices, experience that passive face time influences the evaluated of them. Further, the study aims to understand to what extent that perception of passive face time motivates the employees to spend more time at the office than is necessary for their work situations. The study concludes that employees in general perceive that passive face time does influence how they are evaluated and that this perception motivates employees that are relatively newly employed by the company to spend more time at office..

This was due to lack of maintenance. Since the lab has been an important element in teaching, the University had decided to get the engine functional again. This thesis project has been a request of Mälardalen University.The task we were assigned to was:1.
Mot en grönare organisation : Niscayah i en säker framtid
This paper covers how a company must act to become ?greener? and yet still increase profitability with the main emphasis on the inner structure of the company. The research is focused on the Swedish security systems company Niscayah AB, part of the multinational corporation Niscayah Group with approximately 6000 employees. A company can be assumed to consist of seven parts (strategy, systems, structure, super-ordinate goals, staff, skills and style) that have to cooperate for the firm to be able to become more environmentally friendly. Also, the economic performance is of importance and therefore that too is examined.
Inverkan av stora mängder halm som underlag i grisningsboxen på den nyfödda smågrisens temperaturreglering :
The aim of the present study was to evaluate the effects of large amounts of straw
in the farrowing pen on thermal regulation of the newborn piglet in different
weight classes. 20 sows were given 15 kg of straw in the farrowing pen
2 days prior to until 7 days after parturition. A control group of 18 sows
had no straw in the pen. 6 litters from each treatment were observed.
Measurements of piglet body temperature were made at 0h, 2h, 4h, 8h and 24h
after parturition. At ?8h? the body temperature of the piglets in the Straw group
were significantly higher (P=0,0149) than the piglets in the Control group.
Kompensering av reaktiv effekt vid vindkraftverk

Utveckling av ett kliniskt användbart status för patienter med reumatoid artrit som har höftledsplastik: statuset avser nedre extremitet
Det är vanligt att en patient med reumatoid artrit (RA) förr eller senare behöver ersätta sin höftled/leder med plastik. Efter en höftplastikoperation är vissa rörelser olämpliga för patienten att utföra. Idag finns inget status för bedömning av patienter med RA, som samtidigt tar hänsyn till en eventuell höftplastik. Syftet med den här studien var att utforma ett kliniskt användbart status för bedömning av RA-patienter som har höftledsplastik. Syftet med studien var också att statuset ska bidra till att göra statustagning för RA-patienten säkrare, i avseende att minska luxationsrisken.
Kunskapens värde. Mot en dygdepistemologisk position
"The Value of Knowledge - Towards a Virtue Epistemological Position" The classical question, first posed in Plato's Meno, concerning the value of knowledge constitutes the starting point of this essay. Value analysis has long been neglected in epistemologist's accounts until its re-emergence with the tradition called ?virtue epistemology?, in particular with scholars following Ernest Sosa. Like virtue ethics virtue epistemological accounts changes the focus from the object to the agent, i.e. from knowledge to intellectual virtue.
Redovisning till verkligt värde - En fallstudie av svenska investmentbolag
According to the current regulations described in IAS 27 - Consolidated and Separate Financial Statements, an investment company is required to consolidate all entities that it controls. However, this thesis outlines the creation of a new system, where those entities are instead measured at fair value, taking changes in fair value into account in the income statement. By recalculating the consolidated accounts for five major investment companies in accordance with the new system, this investigation concludes that the new system would provide investors with more relevant but less reliable accounting information. In addition, the historical financial performance of Investor, Industrivärden, Ratos, Kinnevik, and Lundbergföretagen, is evaluated using their recalculated consolidated financial statements. The evaluation indicates that the overall volatility in the companies' consolidated financial statements would have been higher during the time period 2005-2009, in comparison to official reports..
Överföring av digital video via FireWire
Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes the development of a system that receives digital video signals through FireWire. The standard for FireWire, which is a high performance serial bus, is under development. Today the standard of the bus supports transmission of data with a speed of up to 400 Mbit/s.
