In the assembly process of airframe structures there are many drilled holes and on some parts the holes are mainly drilled manually with pneumatic handheld drilling machines. During conventional drilling in metal, burrs appear. To remove these burrs the parts of the structure must be separated and deburred before they can be put together for fastening. This is a time consuming measure and therefore expensive. To facilitate this process and lower production costs some parts of the process needs to be automated.A part of this thesis was a project in co-operation with Saab, Novator, Specma Automation and the University of Linköping.

The health care sector Öster has the highest average absence due to short-time sickness in Örebro. It is the short-term absence that has the highest costs for the organisation, not just in money, but also in quality disturbances and administrative work. Health care sector Öster is divided into four areas with a manager for each. We have chosen to conduct our research within the special housings in area one and four, since these two had the lowest and highest short-term absences.The purpose with the research is to examine short-term absences among the health care personnel in the health care sector Öster, see what the absences depend on, and what can be done to solve the issue. We will compare the absences in the area with the highest respectively lowest short-term absences in order to see if there are any prominent differences between the two.

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

AbstractThis is a thesis done in cooperation with the firm Somas and University of Karlstad. The project is an independent final examination part of the program in Innovation and DesignEngineering comprising 22.5 points, and performed by Mia Myrén Zreloff during spring term 2012. In parallel and collaboration, Fredrik Kjellin performs a similar job for the same company and with the same extent, but for the Program in Mechanical Engineering.The client and supervisor at the company have been Magnus Jansson and Anders Josefsson. At Karlstad University has technical supervisor been Hans Johansson, and in the design- and development process it was Monica Jakobsson. Examiner has been Fredrik Thuvander, professor in the Faculty of Technology and Science at Karlstad University.The mission has been to make a basis work for the company's own development and make a computational model to calculate, visualize and implement materials and other solutions in the manufacture of the company's ball valves.The project has undergone three major phases that included thorough study of the company, production, the problem and product.

Bakgrund: Forskningen kring projekt har under senare år ökat i omfattning. En anledning är att projektorganiseringen utgör ett sätt att samla ett antal specialister för att få dem att samverka mot ett gemensamt mål. Utöver de interna relationer som uppstår i projekt förekommer det även involvering av interorganisatoriska partners i samarbetet vilket är speciellt vanligt i byggprojekt som karaktäriseras av en hög grad av interorganisatorisk specialisering. Problemformuleringar: Den utpräglade specialiseringen inom byggprojekt fordrar som all annan typ av specialisering, samordning och koordinering av resurser med den skillnaden att det här handlar om samordning över de organisatoriska gränserna. Det som denna studie behandlar är därför de relationer byggföretag har till sina underentreprenörer i samband medbyggprojekt.

This study analyses the economic consequences due to ethanol production in Eastern Sweden. The analyses consider the cooperative and the farmers as one vertically integrated company. The area that found the market in this study is illustrated in figure 1. The analyses assume that all members act jointly with the objective of maximizing joint profits at the farm level as well as at the cooperative firm. A mathematical model is created to calculate the optimal use of arable land.

ur society is today in a phase of development in environmental and sustainable thinking. Alarming reports show changes in climate caused by our load and exhaust of resources. The energy usage contributes to a big part of it, by its emission of carbon dioxide. The built environment uses around 40 % of the total energy consumption in Sweden and requests to strongly reduce it are presented from both EU and national level.This thesis brings up the subject of green building with a focus on how we can create more energy efficient buildings in projects of new construction. Since the construction industry today often fails to pass on the knowledge between different projects, as a return of experiences, the construction company Skanska suggested the topic for this thesis.

This master of science thesis intends to examine how the established innovation theoriesinteracts with the social and cultural phenomena arising from the reduction in communicationcosts as a result of the development of the internet.The aim is to present a knowledge inventory of attitudes to and experiences of an openapproach, with emphasis on collaborative innovation, in product and service developmentdriven companies in different fields. The studied theories and the empirical results forms thebasis for an analysis of how companies can benefit from the diversified knowledge that existsoutside their borders as well as an exploration of the potential for this kind of knowledgeexchange to act as a catalyst for innovation.The theoretical part of the study is based essentially on two tracks: (1) innovation theories witha focus onopen innovation and user innovation, and (2) a broad review of how theories ofdiversified knowledgeand collective intelligence has become possible to apply in an innovationcontext. The empirical part of the study is based on material obtained from semi-structuredinterviews with respondents from six companies.The results show that companies have implemented unstructured innovation initiatives withoutany formal links to the structured product development processes, which are part of thecompanies core activities. The main conclusions include the following insights: There is a needfor structured links between the unstructured initiatives and the core activities, which makes itpossible to take promising ideas to market. The companies also have to lose some control of theunstructured initiatives; consequently it is impossible to pinpoint what the outcome will be.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

The economic conditions for Swedish dairy farmers are constantly changing. The numbers of producers are declining and the economic conditions for dairy production are weakening debilitating. To improve the economic situation for a farm a hired contractor is a possible solution since previous studies show that machinery cooperation may be beneficial for the farmers. The aim of this study is to examine the possibility for farmers to cut costs by hiring a contractor for harvesting silage. A comparison between using own machinery and hire a contractor is the starting point of this study. Another aim is to discuss the farmer?s decision process when achieving today?s situation and to determinate what factors affect their decisions. The study is based on cases selected from four farms that today have chosen not to or only to some extent, hire a contractor for harvesting silage.

The bioenergy market has been introduced relatively late in a perspective of the Swedish forestry. Nowadays branches and tops are used more frequently as bioenergy after harvesting. Therefore, it has developed a competitive situation between pulpwood and bioenergy. This situation has even established some questions. Two examples of these are: ? At what top diameter should the final piece of pulpwood be crosscut to get the best economically result? ? Should the top diameter, at the final piece of pulpwood, be crosscut at a thicker or smaller diameter than what is done today? The purpose of this report is to answer these two questions when the harvesting is made motor manually in beech stands.

Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this case bridges or culverts have to be built. There are many different kinds of culverts and depending on what type you choose and how you place the culvert, the watercourse and the water organisms can be harmed in different ways.

Sweden's government says in the bill 2008/09: 140 that military service should be suspended and replaced with a system based on voluntary recruitment. In the essay, I will make an argument analysis of the parliamentary debate on the bill from the 12th of June 2009 with the following questions: On what is the different side?s argument based on? Are the arguments essentially and factually substantiated? Is there a clear political party tendency among the for-/counter arguments? The method is a "Pro et contra" analysis, a logical systematization of the arguments. The analysis will take start in the headline; Conscription should be suspended in favour of a voluntary system based on contract employed soldiers. The presentation of arguments in the analysis will be guided by the chronological order.

Background: Theoretical, it?s been questioned why dividends exists in companies based upon the fact that there is a separation between ownership and control. According to the agency theoretical perception, dividends is used as a manner to unify the interest of this separation, which in turn lower the agency cost, and increase the efficiency of companies.Purpose: The aim of this master thesis is to scrutinize and analyse the association between Swedish firms? owner structure and owner types and their inclination to dividend.Method: We attack the problem with a hypothetical-deductive research method by using the existence of a universal theory, the agency theory. From our theoretical framework we propose a set of hypotheses.
