This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.

AbstractAccording to 3 § in the Equal Opportunities Act should employer fulfil their commitment to their employees and work targeted for the equality in working life. In the report we account for 3?11 §§ Equal Opportunities Act, in purpose to show employer obligations to work actively work for equality between the sexes. This is the main focus of the article and the answer to one of our issue of law. We have also written about how equality work and how the Equal Opportunities Act has grown up, how it work in today?s society and the thoughts about the future.The growth of equality work, the Equal Opportunities Act and a short history are partially written from European law, the Swedish government official reports and in government bills.

The purpose of this Masters thesis is to examine literature on current media events. We see a close relationship between this literature and the media society where we relate Manuel Castells theory of the network society. In this thesis we have chosen books which give different views on three major media events in Sweden: 1 the assassination of Anna Lindh, the former Swedish Minister for foreign Affairs; 2 the Knutby murder and; 3 the Tsunami disaster in Southeast Asia. These books combine fact and fiction in their writing which in media science is called faction. This form of writing has similarities to genres like new journalism and documentarism and can be problematic for the reader in terms of genre expectations because of the mix of fact and fiction.

This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

AbstractTitle: The Swedish real estate companies choices of valuation within investment properties and its further effects on the qualitative characteristics of accounting.-A study of the Swedish real estate companies listed and non - listed on the stock market, after the application of the international rule board.Background and Problem: From January 2005, all companies, listed on a stock market within the European Union, are required to prepare their consolidated accounts using common set of International Accounting Standards, IAS/IFRS. In Sweden, this opportunity has also been given to non-listed companies, to voluntary implement these rules in their consolidated accounts. One difference between Swedish accounting rules and contemporary International rules, deals with the accounting treatment of investment properties, which foremost affects the real estate market?s accounts. In contrast to the Swedish Financial Accounting Standards Council?s recommendation RR 24, the new standard, IAS 40, permits a choice between different accounting alternatives.

The purpose of this Master's thesis is to contribute to a betterunderstanding of children's free time reading book practices by studyingpupils in the school library and their processes of finding and borrowingbooks for themselves to read silently in the classroom, so called free timereading books. The study also includes observations of the staff's role,particularly the school librarian's in supporting pupil's book selection.The empirical material consists of field notes from an etnographic studywhere pupils in 4th grade (aged 10-11) and staff were observed duringthree school library visits. The theoretical framework is inspired byLennart Björneborn's concepts of information practices in libraries:serendipity, integrative library interface, mediation flow and affordancespaces.The study shows that pupils' search for free time reading books in theschool library is relatively routine-based at the same time as it isspontaneous. The process is an interplay with factors such as time,display and interaction in the integrative library interface. In the presenceof adults, finding books becomes an imposed task for the pupils.

Det övergripande målet är att skapa förutsättningar för en effektiv reservdelsberedning och det förebyggande underhållet.

 This thesis is based upon the assumption that in Swedish school today it is a wide gap regarding the information flow when pupils are switching school. This was one of the reasons Skolverket published a report clearly stating that this is the case. The purpose of this thesis is to examine and describe how teachers are working in a teacher team at transitions to see and understand what their work may mean individually, in a group and to the school as an organisation. The questions at issue is to see how the teachers cooperate during transitions and how they notice students in need of extra support and students level of knowledge during transitions. The two last questions at issue is first to see how teachers approach parent?s expectations on the school and the teachers, secondly it is to examine what implications their work will have on the school.

BackgroundAccording to the Swedish Statistics Central Office (SCB) there were 2 064 000 detached houses in Sweden in 2009. The same year Nordea Bank released a report which described an increased interest in private finances among 2,4 million Swedes. Within the area of private finances lies that which concerns real estate. We argue that a house (detached house) is one of the most financially valuable assets a person will ever own and thus the increased interest in private finance is justified.In regard to this, the financial valuation of the property becomes an issue. When discussed, people mostly refer to the market value, which is the estimated value of the property on the open market.

Title: Internal Communication Approach ? A study of the internal communication-channels of the ICA Administration. Background: The ICA Administration is in the process of generating an organizational change with the purpose of improving their external communication. The internal communication, on the other hand, has been put aside and is missing guidelines at the present.  Since the ICA Administration does not know how the staff uses the internal communication-channels they cannot optimize nor develop them. As the literature shows, it is important to choose the channel that is most appropriate for the type of information that it is meant to communicate. Choosing the wrong channel, or using it wrongly, can bring problems consisting of the staff experiencing to receive less information than needed in their daily work. Purpose: The purpose of this thesis is to explore and describe the internal communication between the employees of the ICA Administration from the existing communication-channels and their usage. Method: Through the initial interviews with the staff, the internal communication-channels of the ICA Administration were determined.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

Workplace accidents in Sweden have in recent years increased. Companies are at the same time putting a greater emphasis on preventing accidents and inform about safety and risks. Therefore there is a need to know how to visualize this safety information. This study is based on a part of a project proposed by the industrial company AB Wahlquists Verkstäder, in which they want to visualize their safety information for new employees and existing staff, and also for temporary contractors and apprentices. The purpose of this study is to see what is required of the visualization of safety information and what guidelines that should be followed.
