Purpose The purpose of our study was to investigate the changing nature of volatility during the last 80 years. Like in an American study, we tried to find some trends in the risk of stocks and bonds that would have an impact on the balance of a portfolio of stocks and bonds. At the same time we investigated the influence of inflation on the choice of portfolio. Methods We have used standard statistic tools and formulas to obtain our results. In most cases it was a matter of calculating average and standard deviation.

The first of January 2005 all companies listed on a stock exchange within the European Unionhad to implement International Financial Accounting Standards (IFRS) in their annual report.But is this regulation for the good or worse and does the benefits outweigh the cost? The goalwith the regulation is to make it easier for investors, shareholders and other stakeholders tomake financial decisions, compare domestic as well as international companies at the samecondition. One of the differences with the introduction of the new regulation is IFRS 3 thathandles business combination and how goodwill and intangible assets from the acquiredcompany should be accounted for. The objectives of our dissertation is to identify those listedcompanies that have made one or more acquisition between the years 2005 to 2006 andmeasure their level of disclosure concerning goodwill and intangible assets through theacquisition. We concluded trough the results that positive accounting theory and systemorientated theory didn?t explain all the verities in the companies? disclosures.

New laws and recommendations within corporate governance during the last years have affected the way board of directors work. The board is said to have and fulfill three roles: a control role, a service role and a strategy role. These roles could be understood by three theoretical theories: the agency theory, the resource dependence theory and the stewardship theory. The purpose of this study is to investigate whether, and if so how, the board work differs between two small firms based on these roles, given that one of the firms is a publicly listed firm and the other is a privately owned firm. Using a qualitative case study as research method we find that the board work differs between the two companies when it comes to these roles.

Bakgrund: Från och med den 10 mars 2000 är det tillåtet för publika svenska börsföretag att handla i egna aktier. Det är intressant att belysa hur möjligheten att återköpa aktier uppfattas i Sverige. Syfte: Syftet med denna uppsats är att klargöra hur möjligheten att återköpa egna aktier påverkar ledningen och aktieägarna i ett aktiebolag. Genomförande: Vi har studerat artiklar och litteratur om ämnet återköp. Besöksintervjuer har genomförts på Assa Abloy, Electrolux, Investor, Skanska, Robur Kapitalförvaltning och Handelsbanken Markets.

This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used. Anevaluation of the bagdryers capacity andcapability was necessary.The work started with gathering ofinformation from suppliers of the usedcomponents and from the responsibleengineers for this equipment. Aneducation to learn how the equipmentworked and how to operate it were taken.That was followed by the creation of astudy plan were the tests were plannedto test different parameters effect onthe drying result and to see if thebagdryer managed to handle the bags ofthe correct format in the pace that theequipment should be designed for.The test results detected a need ofdesigning a unit with a function thatholds the bags in place while passingthrough the dryer in order to attainhigh quality results. The results werelater used for optimization of thedesign.

A co-operation is established when a group of people, sharing the same preferences and values, come together in order to satisfy a common need. The co-operative association should be democratic, governed and supervised by its members and open to everyone. The purpose of this article is to, from our ideal type, study similarities and differences regarding the corporate governance of the consumers? and the producers? co-operative movement. The motive behind our choice of alignment is that the mechanisms of corporate governance often are described from the perspective of the joint-stock company, making it valuable and interesting to study these mechanisms from the co-operative point of view.

Den här rapporten behandlar ett system som använder en databas som lagringsplats för loggar. En bra metod för att hämta ut dessa loggar saknades och databasdesignen behövde förbättras för sökningar i loggarna. En applikation för att hämta och söka i loggposter från databasen skapades. En undersökning om hur databasdesignen kunde förbättras genomfördes också. Båda delarna gjordes i ett projekt för att de hörde ihop.

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions. A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.

Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.

I denna magisteruppsats undersöks eventuella långsiktiga samband mellan den svenska aktiemarknaden och aktiemarknaderna i Tyskland, Storbritannien, USA och Japan. Detta sker genom en kointegrationsanalys med Engle-Grangers metod. Undersökningen omfattar åren 1992-2010 och resultaten visar inga tecken på att det skulle existera några långsiktiga samband mellan den svenska aktiemarknaden och någon av de utländska aktiemarknaderna. Resultaten ger därmed indikationer om att den svenska aktiemarknaden tillsammans med de utländska aktiemarknaderna i undersökningen är kollektivt effektiva i åtminstone den svaga formen enligt Fama (1970). Då inga långsiktiga samband existerar bör även portföljdiversifiering mellan den svenska aktiemarknaden och de utländska aktiemarknaderna i undersökningen fungera effektivt på lång sikt..

Since January 1 2005 all companies listed on a regulated stock exchange within the EU are required to present their consolidated accounts in conformity with IFRS. Among many other consequences goodwill will no longer be amortized over its useful life but instead annually tested for impairments in accordance with IFRS 3. The aim of this paper is to scrutinize the impairment test of goodwill as outlined in IAS 36 and analyze its implications. We conclude that the impairment test will probably lead to the recognition of internally generated goodwill in the consolidated accounts. We also conclude that the impairment test on highly aggregated levels will probably hasten the pace of this recognition since internally generated goodwill is used to shield acquired goodwill from impairments.

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.
