Flow i fokus : processen att göra ett spel genom research through design
Starting out as a minor form of amusement, the game industry has become one of the most lucrative andsuccessful in the entertainment business competing against giants such as television, movies and music.As the internal competition within the developer community grows companies work hard at discoveringnew ways to attract and keep customers. By having a playcentric approach focusing on user experiencethey hope to achieve that goal. This thesis describes the process of designing a game with focus on theplayer. We apply the concept of flow on game development and investigate through research throughdesign if we are able to create a game that keeps the player in flow.Play tests showed several elements such as control issues and too difficult challenges early in the game,affecting the possibility for players to experience flow while playing. These negative factors came to becalled flowleakers.
Enighet om Europa Applicering av diffusionsteorin på utvecklingen av attityden till Europeisk policyintegration 1999-2009
Public opinion has increasingly become a political force in the European integration process. At present, it appears that the people?s attitude towards the European integration is relatively skeptical. How can we expect that the attitude towards European integration will evolve in the future? This paper tests the extent to which diffusion theory can serve as a model to explain the development of attitudes to European integration policy in Sweden from 1999 until 2009.
Arbetsmiljövänliga låsvätskor i stötdämpare
This master thesis is a study of anaerobic thread lockers and is done in cooperation withÖhlins Racing AB, which is a Swedish manufacturer of vehicle suspensions.The suspension in vehicles is constantly exposed to high vibration levels and a suspensionunit has several screw- and cylindrical joints. As an extra safety precaution so that thecomponents in the suspension doesn?t fall apart when using the vehicle, an anaerobicthreadlocker is added in these joints. The handling of these threadlockers is not totallyharmless and could lead to allergic reactions, and therefore there are Swedish laws to limit theuse of these. However, new types of anaerobic threadlockers have recently been launched onthe marked that are not considered under this law.

We designed a website for a small clothing store and conducted usability tests, in order to evaluate the users clicks and eye movements in relation to design choices on the website. The aim of this study was to research how these tools can be integrated in usability testing and how results from the tests can be used to improve usability. We were able to use the recordings of clicks and eye movements and make design changes based on the findings.
Nytta, skada och kostnader vid screening för bröstcancer med mammografi
The efficacy of screening for breast cancer with mammography has been a subject of controversy during the last decades. However, the general opinion is now that screening reduces mortality in breast cancer (Zackrisson, 2006). It is nevertheless important to weigh the efficacy against the harm and costs associated with screening. Cost-utility and cost-effectiveness analysis of screening have generally failed to incorporate side effects such as anxiety and discomfort related to screening tests and the following diagnostic tests (Gyrd-Hansen, 2000). This study seeks to include such side effects in a cost-utility analysis.
Avståndsvarnare till Mobiltelefon
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.

Laboratory tests for sperm quality and fertility in stallions
Syftet med denna litteraturgenomgång var att presentera några av de vanligast förekommandelaboratorietesterna som används idag vid utvärdering av spermakvalité hos hingstar. Engranskning har också gjorts för att försöka utröna om det går att förutse hingstars fertilitetutifrån resultaten av dessa tester. De metoder som presenteras analyserar motilitet, morfologioch funktion hos spermierna i ett ejakulat. För att kunna fullfölja en befruktning krävs det attspermien uppfyller vissa kriterier. Detta för att kunna ta sig fram till äggcellen och smältasamman med denna och bilda ett embryo.
Gymnasieelevers upplevelser av hälsoprojekt : -en kvalitativ intervjustudie
Studies show that children?s and adolescents health decreases, especially the mental health. There are today many health methods that flourish in the school area. Methods that is external and used as individual interventions and methods that have the intention to integrate health in all aspects of the school curriculum.Research on health projects often show what the intervention or method has produced. Few studies have been found who discuss the pupil?s own experience regarding health projects.
Lokal konservering av bok med mögelskador Förstärkning med Klucel® G
The aim of this paper is to make a plan for local treatment with Klucel® G of a book with moulddamage. The biggest problem concerned handling the book without loosing fragments and tohandle pages that were stuck together. In some places as many as six pages where stuck togetherand it was not possible to separate them without loosing material or breaking them. The otherproblem concerned the use of waterbased adhesives that might cause tidelines and paperdistortions as seen in another volume. The use of Klucel® G dissolved in ethylalcohol functionedvery well as strengtheners and also as an adhesive for lamination.
Begreppsbubblor/Visuella representationer i matematikundervisningen : En studie om bemötandets och undervisningens betydelse och möjligheter för elever med koncentrationssvårigheter
The aim is to examine how students with attention difficulties may demonstrate their mathematical understanding through visual representations. A curiosity about how students think about mathematics, national tests and Concepts cartoons has also permeated the study. With help of observations combined with interviews and actively work for a week, the study shows an idea of how visual representations can help students with concentration difficulties to stay focused on their tasks. I chose a selection of pupils to do some mathematical tasks from the national tests which they had not been able to solve before. Now in the form of Concepts cartoons, which I designed, they managed to solve the same mathematics data. In my study treatment and interaction reveals as key pillars for a successful educational work with the students with concentration difficulties. Thus, all pupils who previously have been unable to solve these assignments on the National test were now able to show their mathematical understanding supported by visual representations..
Polyfona positioner i pendlande praktik
The purpose of this study is to contribute to our knowledge about what methods? teachers say they use in the work with pupils? early reading acquisition, and how they evaluate the pupils´ reading development. I also like to find out what educational interventions teachers believe that pupils with reading difficulties need, and how they say they work to meet the needs of these pupils. The project is based on the following questions: What methods do teachers say they use in the work with pupils early reading acquisition? What extra resources do teachers consider that pupils with reading difficulties need? How do teachers evaluate children's reading development? In order to answer my questions, I've done qualitative interviews with three teachers, at two schools, in two medium-sized municipalities.
Konstruktion av testrigg för moderna ångexpandrar
This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.
VD-karusellen : En eventstudie om en VD-avgångs påverkan på marknaden
The goal of this study is to examine how the market reacts when information about the exchange of a CEO becomes public. It also examines factors such as gender and whether the departure was voluntary or not, discerning if the market behaves differently concerning any of these aspects.To achieve this, the study was performed using an event study. The selection consisted of 48 companies on the Stockholm Stock Exchange, who had during the years 2005 to 2008 underwent a change in leading management. These units were submitted to hypothesis tests, to determine if an abnormal return was attained during the event window. The tests were performed on the units as a whole, and divided up after gender and whether the departure was voluntary or not.The results of the study show no statistically significant abnormal return caused by the announcement of a CEO exchange.
Design and Analysis of an All-optical Free-space Communication Link
Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.
