The task for this thesis is to design a tool that is used to cut-out preforms of thermoplastic adhesive and also to make an estimate of costs for the stamping tool. The tool is used in the repair process at the MCM production line. The result of gathered information has affected how the design of the stamping tool has developed. The handling of thermoplastic adhesive in the repair process is one of the factors that influenced the design. The adhesive is sensitive for exposure to moisture. Therefore an automated feeding system of the adhesive is not recommended. The users wished for an automated stamping tool.

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

Stratego is a boardgame not very different from chess, that contains hidden information. Because of this, existing programs play at beginner level. The purpose of this thesis is to adjust a minimax algorithm so that it passes the demands of Stratego, and then build a Stratego agent around it. Tests with existing minimax algorithms leads to the development p-e-minimax. This algorithm uses two different values in its nodes to simulate the different information available to the agent and its opponent.

This essay examines the process of fair value accounting of financial assets in a Swedish commercial bank, in contrast to the theoretical approach stated by IASB. The theoretical background contains a review of the academic standpoint on fair value accounting and historical cost accounting, a detailed description of fair value accounting according to current and future IASB regulation and on the American FAS 157 regulation. The empirical case study describes the process of valuing and classifying financial assets into level 1 and level 2 of the fair value hierarchy. The analysis describes how the legal requirements for classification are interpreted and applied in practice when valuing bonds and derivatives. The authors provide an explanation as to why the majority of financial assets are valued mark to model rather than mark to market as well as a suggestion on how the share of market valued assets can be increased..

The purpose of this masters thesis is to examine the fanzine, a form of amateur publication, in Sweden, both in the traditional paper form and the more recent electronic form. It deals with what is distinctive about the fanzine as a publication and also as a social and cultural product. It also looks upon how the fanzine uses the Internet and the new possibilities it brings. The people behind 18 fanzines, 10 electronic and 8 in paper, have answered a questionnaire about how they produce, publish, distribute and promote their fanzines, what they think about the fanzine as a mode of expression, and how they use the Internet. The masters thesis uses theories within cultural studies as a theoretical approach to the fanzine.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

The purpose of this study is to highlight how a ring road and an external retail establishment may affect the city commerce. Umeå is the study object with interesting undergoing changes including a new external retail area south of the city and a new transport route that will lead the through traffic around the city.The study is based on a review of previous studies and a qualitative method. Four interviews were conducted with people who have a connection to commerce and/or municipal planning and where considered able to contribute with rich and relevant information. The result shows that the commerce in Umeå will be significantly strengthened in the context of a new external commercial establishment when the city?s overall attractiveness increases.

The aim of this thesis is to study the teaching methods that provide the greatest learning effect for children in grades 6 in the subject of physics. One class was divided into three equal groups, each group was educated in a specific way. The three teaching methods that have been investigated are: film with reflection, laboratory work and traditional lecture- teaching. The research question of the study is: "Which method of three selected, causes the greatest understanding of the properties of air??.

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

The number of young women who self-mutilate in different ways has increased dramatically in recent years. Self-mutilation is a way of trying to feel better for the moment. People who self-mutilate often have some other underlying illness such as borderline disease. Women are overrepresented in this group of people and their behaviour is often rooted in a history of childhood trauma, sexual abuse, and psychic maltreatment. The aim of this study is to reveal thoughts about the future among young women who self-mutilate.

The purpose of this examination is to identify how notions of Swedishness is created artistically, and from where these notions come. My method is to make a study on exhibition catalogues on the theme Swedishness/Nordism, with focus on the contemporary Swedish artist Peter Johansson. With a retrospect of his childhood in Dalecarlia, he investigates a Swedish iconography with it?s roots in national romanticism, which for more than one hundred years has been preserved and exploited of the tourist industry to market Sweden. It?s this monotonous iconography that Johansson deconstructs to make it appear like something else ? namely an iconography based on ethnic purity, which pushes away the foreign and protects the own.

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.

It becomes increasingly more important that, as a new buisness, both to be seen and heard in an increasingly harder competition situation where the range of similar products and services increase. It requires a well planned and well thought visual profile to succesfully stand out on the market. To give a good impression, this profile should be both distinct and aesthetically appealing. In the making of a new profile it requires creativity to succesfully think in new directions and to separate from the competition.This practical report presents the production process for a designsolution to the new website Röstförmedlingen (Voice agency), a commission from the production and commercial bureau Bartos media. The task in this project was to create a graphic profile and a lofi-prototype that would represent Röstförmedlingen as a buissness.

This essay examines migration paths through Sweden. There has been a debate in August 2010 that Sweden is regarded as a backdoor for non European immigrants to come over Denmark. It has been discovered through Denmark?s statistics and is regarded as negative by the Danish government. Denmark and Sweden are two countries that are socio- , economically- and culturally similar, but went in two different directions, especially with immigration policy.

Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.
