In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

The purpose of our study was to examine how three teachers and four students relate to the program "Fem myror" in teaching. We have been through qualitative interviews with two teachers and one special teacher received a detailed picture of how their literacy programs made in relation to the "Fem myror." Qualitative interviews have also been made with four students, a boy and three girls, in order to examine their attitude to the program. From educators? interview answers, we think we can say that the theory and practice conform to what we read in the literature may be associated with what we observed during our time in the business. The study has shown that all teachers believe the program will be a good educational tool to take to read and write.

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..

Every business is subject to service failures. The process of correcting these failures and turning disappointed customers back into happy ones is called service recovery. This is particularly important in the hotel business, where there are many moments of truth where customers may become dissatisfied. To further complicate things, service recovery is a process where you may have to correct errors of others - people beyond your control. The research field is relatively new and there are no turn-key solutions as to how to systematically work with service recovery.

In order to validate the results from my theoretical analysis I conducted a series of interviews with a number of professionals who useBusiness Intelligence research in their work and decisionmaking process..

LEXION is the name of the largest series of combines made by the CLAAS factory in Germany. LEXION was introduced on the Swedish market 1996 and was for sale in Sweden from 1997. LMB have sold over 400 LEXION-combines in Sweden. In cooperation with the Swedish general agency we decided to make a market research on the Swedish LEXION-market. The questionnaire was supposed to give answers about capacity and technical equipment. Before I made the questionnaire I studied manuals and combines. I got 81 answers of about 325 questionnaires. That makes 25 % reply frequency.

The Barbie doll is an icon filled with meanings; this thesis discusses the Barbie doll and herfeministic potentials and subject positions using a discourse analysis. The thesis analyzeswhat sort of femininity Barbie portraits in magazines, web series and films about her.Theories being used originate mainly from gender and queer studies, where the focus is on theperformative constructions of gender and femininity. Since the material mostly consists ofmoving images some influence is taken from feminist film theorists and semiotic theory,which focuses on signs and their meaning. The thesis centres around the questions: how isBarbie?s femininity challenged, strengthened and constructed in different types of mediaabout her produced by Mattel? And is there any feminist potential in Barbie?s subjectpositions in these media forms?.

This report looks at the possibility of designing a universal adapter for Flat Blade windshield wipers in cooperation with European Automotive Supplier AB.To understand and see if this is possible, a research and an extensive patent search where done. Then to add structure to the project a Ganttschematic were developed. To generate good and solid ideas, different methods for product development were looked upon.When a method was chosen and applied, a series of concepts emerged. Now the focus was to design and construct all the pieces. The desired manufacture procedures were looked upon as well as materials.

The purpose of this master thesis was to study the librarians?assignment at the public accesses computers, especially howthe librarians perceive what their task is and what their taskshould be.In order to answer these questions a series of ten qualitativeinterviews ?inspired by the phenomenographic approach ?was conducted with librarians who were employed at smallpublic libraries in municipalities with 5 000 - 25 000residents in Sweden.The conclusions in the master thesis were that librarianshave both similarities and differences in how they perceivetheir tasks at the public computers. The most essential taskwas helping the user with information seeking. Thelibrarians also perceived that it should be included in theirduties to help users with the technical/practical issues at thepublic computers. Competence, time and assets were finallythree outlying factors which affected in what extent thelibrarians were able to help the users..

Permaculture is a design system that aims at developing sustainable human settlements and self-maintained agriculture; it may also be used for community planning. The design system of permaculture aims at mimicking a natural ecosystem; this gives the advantage to make use of all the connections and mechanisms that exist in such a system.The purpose of this bachelor thesis was to compile and spread scientific information regarding five different themes within the areas of ecology, environmental science and permaculture. This was achieved through cooperation with the permaculture inspired Ecovillage Suberbyn in southern Gotland. Information about the central parts of a permaculture ecovillage was used as material for a series of signposts that will be located around the ecovillage Suderbyn. The five selected themes were: An overview of permaculture, The forest garden, The pond, Composting and The use of human excrement and urine..

The purpose of this report is to analyze and evaluate non-profit organizations way of working with social media within the organization, from a marketing perspective. We have made observations of three organizations and completed a series of interviews with representatives within the organizations.In the report we came up with five factors that are necessary for non-profit organizations in order to receive long term donations with the use of social media; Trust, awareness, involvement, interaction and Word of mouth marketing.Our result shows that the organizations have realized the potential and benefits of using social media, but have not come very far in the process of using it properly. Our conclusion is that social media can give assumptions for long term donations, if the organizations use a customer perspective and give their customers added value..

What kind of international actor is the European Union and how shall we define it? These are questions that many have tried to answer often by addressing the apparent uniqueness of the EU itself. One of these theories is Normative power Europe. A theory whose main argument is that the EU is best perceived as a changer of norms. My aim with this thesis is to test this claim and to see if the Union should be regarded as a normative power.

The objective of this study was to examine how an IT department has been affected by the changes of increased local usage of IT, and how the usage have affected municipalities IT departments demands of IT support. In the study we explore how both the IT department and the IT support works by interviewing present and former employees at the local IT department. The current IT department have undergone a series of local changes over the last 20 years, the department has gone from only having internal users to getting the entire municipalitiy?s agencies of IT as users. It started with how the municipality began to dig down fiber optic cable in the middle of the 1990?s, and today has started to develop solutions as to how to meet the demands of future usage of IT.

The base for the study is laid during an internship at a regional office in Brussels. The study initially concentrates on the function and activities of different regional offices located in Brussels, in order to answer the core question.The main focus is to reveal an eventual change of cooperation patterns between different regional offices, and in particular the eventual redirection away from a main cooperation between offices deriving from the same national state.Through an empirical material, based on a series of interviews, an analysis is made using three hypotheses concerning the patterns of cooperation among regional offices.The notion of a coming change stated by, in particular, two older studies is used as a theoretical steppingstone with the conclusion that a change, in the way offices collaborate, has taken place..
