This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

Abstract The main purpose of this study was to investigate if and how the employees in elderly care experience stress and which underlying causes they understand to be important in their work situation. The purpose was also to investigate whether Karaseks and Theorells demands and control models could be used to explain the employees feelings of stress and to see in which categories the participants are in. Furthermore, the purpose was also to understand the participants work situation and to describe the factors and remedies the employees perceive to contribute to the stress levels at their workplace. 81 questionnaires were distributed at three different locations, two of which were in Ronneby and one in Örebro. 56 people answered the questionnaires.

The Swedish Armed Force is one of the largest authorities in Sweden and has as its primary mission to be responsible for Sweden's military defence. Their unique activity - to participate in armed combat ? requires leaders who can make quick and rational decisions in uncertain and conflicted environments. This study aims to gain an understanding of how individuals with leadership roles in the Swedish Armed Forces are experiencing their leadership in relation to the organization's structure and culture. In order to achieve the purpose of the study, the following research question was created: How do individuals with leadership roles experience the influences of the organization's structure and culture on their formal leadership? The theoretical starting point is Weber's organization theory, Schein's organizational culture theory, and different definitions of leadership.

AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

The accounting of today results in reports that are valued according to one kind of value.There are advocates who recommend that the accounting should be expanded by one orseveral columns, which would enable that other methods of valuation could be used. In thisessay we examine how the ?multi column reporting? can alter the outcome of a financialanalysts? valuation procedure.In this essay we used existing theories about the financial analysts? usage of information toreach the lack of information we found and which we aim to erase whit this essay. To do thiswe studied decision theories and theories regarding information processing, and by interviewswith three financial analysts. After we collected the information needed for the analyses, wethen also compared the results of the interviews with related theories.The theories about decision in this essay concern whether a decision is based on rationality,bounded rationality or irrationality.

There are several methods and models within the areas of software engineering on how to proceed during a software development process. For each of these methods and models there are benefits and drawbacks, depending on how you choose to look at them. A difference of principle between the different models is that they either advocate iterative development or not. In parts of software engineering one makes use of different methods depending on which is most fitting in a specific situation. There are several methods on how to recieve more qualitative data from the end-users during the requirement collection, but the reappearing pattern is still user centric participation, which means that the user participates more actively in part of or the entire development process.

Today, there are a number of different models and methods used to estimate the equity value of a company. A common tool for valuating stock prices is the usage of different multiples. This is a method used to determine the value of a company, by examining and comparing the financial ratios of relevant peer groups. The disadvantage with this method is that it does not take all the important aspects, such as risk, investments and capital structure, into consideration. However, this study investigates if the key value, called discounted cash flow (DCF), can be integrated with the valuation of the multiples.

In this essay, I discuss one of the recurring dilemmas for a working recreational pedagogue, namely the hard task of cooperation with parents. As a recreational pedagogue, I am required to work by the curriculum Läroplan för grundskolan, förskoleklassen och fritidshemmet 2011. This policy document talks about what my responsibilities are, including establishing collaboration with parents in terms of the children?s development and education. It happens, however, that the pedagogue and the parent's ethical positions differ.

In agricultural educations you learn to use different economic planning tools, as basis for decision. The purpose and goal of this work has been to find out if economic planning tools are used by the farmers in Sweden. We choose to do an investigation through personal interviews, and used an inquiry to get as equivalent answers as possible from the farmers. This work contains a literature study with relevant facts about the questions that is brought up in the inquiry. This study of literature explains shortly some different calculation methods and bases for decision. It also contains useable information that is important to know before an investment. The questions that are asked to the farmers have focused on the use of calculation methods and economical planning tools.

Today many industrial companies invest a lot of resources on research and development to resist the tough competition on the global market. This leads to a high risk game when the companies start many development projects, with uncertain outcome where some of the projects have to be terminated prematurely. The main purpose with this study is to identify factors, both internal and external, that influence the decision to terminate projects prematurely in Swedish development projects. Factors mentioned in the literature will be compared with case studies on three Swedish industrial companies to demonstrate the most important ones when taking such decisions. First a literature study was made to identify basic terms, a general project model and factors affecting the decision.

Since the 9/11-attacks several nations have been confronted with a new international threat, its nature traces back to the political- and religious- radical movements of the 20th century Cold War. Ever since, various states have been under threat by terrorist organizations around the world due to mainly participating in worldwide counter-terrorist interventions created by western alliances. In Sweden, amongst other countries, the state took security-precautions that would imply total control of information throughout the territorial borders. The assigned proposition was accepted by the Swedish parliament in June 18th 2008, after this date wild spread criticism was still in effect ever since the Swedish government first publicly announced the proposition in May 8th 2007. This study emphasizes on understanding why the Swedish government chose to present this proposition to parliament, in order to complete this task the study will present the motives and the alleged threats that were the core of the proposition and its value-maximizing goal of creating a new surface for Swedish homeland security.
