Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

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.

This thesis work aims to describe the prerequisites for a distributed treatment platform for real-time sharing of rounds performed by paediatric oncologists. The work started during the autumn 2004 and is directly aimed at improving the situation for the thirty or so specialist treating children with cancer. The work is not limited to the description of such a platform but also to select suitable software and hardware for the implementation of the platform and further more to coordinate the implementation. The production of several documents describing the platform is also part of this work.

Ett flygsäkerhetsarbete bygger på ett förtroende mellan individen och organisationen. Det finns en brist inom Försvarsmakten rapporteringssystem, där fördelningen av rapporter med avseende på mänskliga misstag, är avvikande från vad som anses som normalt inom flygverksamhet. Varför avviker rapporteringen i FM från normalbilden? Ett perspektiv som kan förklara denna avvikelse är rättvisekulturperspektivet.Syftet är att diskutera huruvida den ojämna fördelningen av avvikelserapporter med avseende på mänskliga misstag i FM flygsäkerhetsarbete kan förklaras ur ett just culture perspektiv med fokus på regler och styrdokument .Resultatet är att FM inte är att anse som en rättvisekultur. Framförallt är detta på grund av den bristfälliga kulturella grunden, disciplinsystemet och skyddandet av rapporteringssystemet..

Financial bubbles are characterized by a large increase in the economic growth on the market as a whole or in specific industries. The change gives rise to an increase in the capital needed to finance this growth. Companies typically have a choice between equity and debt capital to finance its business and the mix of these types of capital is often referred to as the company?s capital structure. There has been a lot of research done in the field of financial bubbles and ofcapital structure, as of yet no studies seem to address these two areas in combination.The aim of this study is to examine if financial bubbles affect a company?s capital structure and through this also examine if the supposed changes in capital structure can be generalized.The study comprise of two identical time-series which examines the changes in leverage and the choice of financing during the Swedish real estate bubble in the early nineties and the IT-crash at the end of the 2000th century.

The aim of this study is to study how sustainability policies are implemented and perceived in the operations of a Swedish fashion company. The fashion industry is affected by strict controls when it comes to transparency and reporting of sustainability efforts. This contributes to a strong focus on sustainability. The theoretical framework revolved around institutional theory where the phenomenas of decoupling and recoupling were central. A qualitative case study was conducted where interviews were the primary source of data.

Banks carry a great responsibility when it comes to the financial systems in our society. Disturbance in the credit system affects both lender and borrower. All financial institutions must therefore carefully estimate their risk exposure. This assessment enables them to cover themselves from losses with appropriate capital buffers as main guardian. In order to prevent bank crises and also to maintain financial stability in general, new regulations concerning analysis and preventive actions were introduced on the 1st of February 2007.

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.

As most developed countries Norway has an ageing population meaning that the number of pensioners is predicted to grow rapidly over the coming years. As a consequence the Norwegian pension system will not be able to provide for these future pensioners. Meanwhile, a rising number of early retirees and disability pension claimants is diminishing the real retirement age. Also the individual pension amount is growing while the pension system itself reaches maturity. In short, major reforms are needed in the Norwegian pension system.

The aim of this essay is to see how the IOGT, local politicians and the local newspaper acted in the city of Hedemora in Sweden in connection with the referendum held in 1922 whether or not to ban the use of alcoholic beverages. To accomplish this I have examined protocols from local IOGT-groups, the town council and the local newspaper Södra Dalarnes tidning. I find that the local IOGT not only worked with the issue of alcohol but served as an institution that deepened democracy and education in the local community through discussions, study circles and applying pressure on local politicians. The locally elected bodies in turn were generally in favour of the good work the IOGT did, although not always overwhelmingly so. Many of the local politicians that handled the issues of alcohol were themselves active members in organisations promoting absolutism.

In this thesis we study the development of post-earnings announcement drift (PEAD) in the Swedish equity market from 2000 to 2009. By forming portfolios based on the stock price reaction to quarterly reporting we show that the characteristics of PEAD have changed. We demonstrate that negatively surprising companies show a positive drift during a holding period of six months sufficiently large to render the trading strategy unprofitable. This development holds from 2005 and onwards and these results contradict many a study which finds the same portfolio construction to be indeed profitable. We argue that this development is a trend that will not only affect our study but future studies as well..

The purpose of this essay is to examine how two riding schools work with their safety. Riding is one of the most popular sports in Sweden but also very dangerous. Sweden has a lot of riding schools and almost half a million that rides. Therefore it?s very important that riding, and especially riding at riding schools has the highest level of safety with regards to harmful events.The purpose leads to the overarching research question for this essay, which is: How does the Safety work look at two riding schools in the area of Karlstad? Out of this question, seven specified research questions have been constructed.
