The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.

In the 1940s the Swedish town planning was inspired by the English city development with the concepts of neighbourhood and community planning. In order to promote democratic development and solidarity the ideal would be to create community centers with full service. Community centers are part of the building of the suburbs during the postwar period. The buildings in Sweden from 1940 - and -50s were built with the intentions to be good homes for all regardless of income, class and status. Collective solutions to individual problems were characteristic of the Swedish policy during this time.

This master thesis was conducted at Motala Wire Works Ltd (MWW) in Motala during the autumn and winter of 2007-2008. The thesis named ?Future layout of Motala Wire Works? focuses on making a better planed layout for the factory, which also take in to consideration future changes.Motala Wire Work produces wire mesh products of varying sorts for the white goods industry. The factory was started by Electrolux during the 1950?s.

An increasing number of applications are becoming more or less network based today.The traditional architecture for network based applications is client-server, but as usageof download services are going up, so is the Peer-to-Peer architecture. This report is acomparison between the Peer-to-Peer and client-server model, and can serve as a basiswhen a decision between them needs to be taken. In the report, the performancebetween the different architectures is compared in different contexts. Our basis is ageneral implementation of both architectures in a test that is derived from a previousreport. On top of this, the performance of the different architectures are measured,implemented in a gaming-context.

Syftet med vår undersökning var att undersöka om extrem-/äventyrssport hade en plats i kursen idrott och hälsa A. Vi valde att skicka ut förfrågningar till 20 skolor i Malmö och grannkommunerna, av dessa fick vi svar från tio och endast fyra ville delta i undersökningen. Detta gjorde att vår undersökning omfattar fyra intervjuer med utbildade idrottslärare på fyra olika gymnasieskolor i sydvästra Skåne. I vårt resultat kom vi fram till att tre av lärarna hade extrem-/äventyrssport vid ca fem lektionstillfällen per termin, och en hade inga lektioner alls med denna typ av aktivitet. Det var många faktorer som spelade in när lärarna beskrev varför de inte hade så många lektionstillfällen med anknytning till extrem-/äventyrssport bland annat tid, resurser, skaderisk, engagemang och förutsättningar i närmiljön. Alla lärare vi intervjuade hade en positiv inställning till extrem-/äventyrssport i skolundervisningen och skulle gärna vilja få in fler lektioner med denna form av aktivitet, eftersom det hjälper att stärka elevers självkänsla, ger en allsidig träning och är ett bra verktyg för teambildning. Tre av dem såg det som väldigt viktigt att idrottsundervisningen i skolan följde med i utvecklingen, anammade de nya aktiviteter som ungdomar sysslar med utanför skolan och att extrem-/äventyrssport hade blivit ett stort fenomen i samhället.

The game industry is growing by every year but for some reason the research surrounding it hasn't caught up with its rapid expansion. This study aims at expanding the knowledge surrounding one of those areas, player motivations. An empirical model has been used to identify which interaction has the highest impact on player motivation in story-driven roleplaying-games. By conducting semi-structured interviews with eight different game developers using the GameFlow model to explore the use of interactions to sustain the motivation of the player a new criteria has been identified. This additional criteria was: Alive, and it was shown to have a high impact on motivation in story-driven roleplaying-games.

Studies have shown that politicians are significantly more likely to become victims of violent crime than other citizens in Sweden. In fact increasing political rank and engagement are directly proportionate to increased risk for violence. Threat towards politicians is not only dangerous to the individuals involved but also to the democratic system as a whole.Political scientists the world over have done a lot of research on democracy, but I have been unable to find a single method or theory that examines how violence, threat and harassment affect political leaders and democratic systems.The aim of this study is to expand the existing model made by Tommy Möller, professor in political science. In his model he presents 11 factors that affect political leaders ability to act. My aim is to develop his model by adding a 12 th factor ?violence, threat and harassment?.

Title: Bottleneck management through materials administration Course:  4FE05EAuthors:  Mikael Karlsson and Johannes Mueller  Examiner: Helena ForslundKey words:  Bottleneck management, material management, process description, timber, proceduresPurpose:   The objective of this study is divided into three parts, all three parts of the purpose aim for the same goal. Namely, to improve the material management so that this enables the bottleneck in the planing mill to keep a continuous  flow, and thereby minimizing the risk for production stops at LB-Hus.  Part.  1:  Identify  and  analyze the material management  connected to  the planing mill  in order to identify problem areas.Part.2:  Identify  improvement potential  in the material management connected to the planing mill.  Part.3: Suggest improvements in the material management connected to the planing mill. Theoretical framework: Process mapping, inventory accounting, balance safety, inventory availability / service levels, safety stock and reorder point, forecasting and routine descriptions.Empirical foundation:  Interviews carried out at LB-House,  illustrated with the help of process maps and a description of each process.  Conclusions:  To work with  the  suggestions  given  and  to  follow  clear procedures  in  all  processes would  result in  a more  efficient  inventory management,  it would also present  a  solution  to  the problem regarding the planing mill being a bottle neck.Suggestions for further research: Review and map the information flow from demand to production start.

Every organization goes through the same lifecycle. Through every step in the transformation to a better organization the communication structure changes. In this report there are examples of the communicational disadvantages that is connected to the communicational structure.By choosing to not have a formal communicational design, the manager takes a risk in spreading the information, the interaction, the control and the balance in creativity and constraint.This case organizations problem is that some parts of the organization has made more progress in the communicational structure than other parts. In this case the Collectivity structure has met the Formalized structure.Tha structural differences has came to affect the way of sharing information and it has become a situation where the information about the products is not stored in a safe way from a quality point of view. There is a gap between the two different ways of communicate.In this report I have created a model to identify problems in the communication structure.

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.

The purpose of this study is to examine the phenomenon ?Living library?, where people are lent out instead of books. First it is looked into what the Living library means to the person who is borrowing a living book and what it means to the living book itself. Than the Living library is put in a public library context. This is done through a case study of the city library of Helsingborg and the city library of Malmö.

Background: We have identified the combination of Knowledge Management and Human Resource Management as interesting because of this constellation has been mentioned scarcely in previous studies. There also seem to be some interesting correlations with personnel turnover.Aim: The aim of this study is to describe and understand the theoretically best combination of Human Resource Management and Knowledge Management, by creating a model. The model is also going to be tested empirically through consulting firms, to see if they meet the ideal combination. With this model we also want to describe in what way the different combinations of strategies will affect the personnel turnover.Definitions: A huge part of this study concerns the theoretical area Human Resource Management, which we have entitled HRM. Similarly, Knowledge Management has been entitled KM.Completion: The study is designed both as a literature review and as a comparative case study in which empirical data has been collected through qualitative interviews with four Swedish management consulting firms.Results: The best combinations of KM and HRM are according to this study that strategies should consist of a thoroughgoing personalization or codification.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews.

The neo-classical conception of the market place does not provide a framework to account for ethical or moral action. As a result, the neo-classical model is unable to explain the impact of ethical and moral issues on business sustainability present in the modern economy. To address this limitation, this thesis investigates whether theories of ethics can help explain the motivations and actions of stakeholders within the field of Corporate Social Responsibility (CSR). In addition, the thesis explores whether theories of ethics are presented differently within aspects of the stakeholder model. Semi - structured interviews were conducted with various stakeholders within the CSR sector, including a NGO, a commercial firm and a CSR consultancy firm.
