Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Background: Oil is the most dominating source of energy of today, it constitutes for more than 40 per cent of the worlds total energy consumption. This together with the fact that stock in oil companies has soared on the stock exchanges around the world makes oil a very interesting topic to write within. In order to gain knowledge in how to value oil companies, the authors will collect information from theory and through a questionnaire. By applying the information gathered to three companies listed on the Stockholm Stock Exchange the authors will reach an objective picture of valuation of oil companies.Purpose: To investigate how shares of stock are valuated in the oil exploring and producing industry, and what specific measures and metrics that are used in the valuation of stocks in Exploring and Producing (E&P) companies.Method: By using a qualitative approach for this thesis, the authors will investigate how the valuation of oil companies works and what measures that should be applied. The authors will use a part descriptive and part explorative study.

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

The purpose of this master thesis is to present a model that illuminates the important factors when deriving technical information from market data within a company. For companies to be able to become and stay competitive in the market, product quality is an important factor. Whilst good product quality leads to customer satisfaction and loyalty, lack of quality brings costs in service and replacements. To improve product quality, the developers need information and knowledge about what quality issues affect existing products. Most companies gather data from market about known issues, but in order eliminate known quality issues in new products; this data has to be transformed into information and knowledge.

Today we are living in a knowledge-society where knowledge sharing is of utmost importance for companies in order to keep their competitiveness. Therefore, it is a much debated issue - in both the academic and the corporate world - in what way one should handle the knowledge which continuously is created within companies. The aim of this study is to describe how practitioners share tacit knowledge within a large knowledge company. By that we aim to get an answer to how the chosen theoretical models regarding tacit knowledge relate to the empirical world. In this study we will focus on tacit knowledge in contrast to explicit one.

It is important, for companies operating on a homogeneous product market, to understand and adapt to customer needs. Since coffee is a homogeneous product in food retail it is vital for coffee companies to work extensively with differentiation and the fierce competition. The prevailing homogenity makes it difficult for companies to develop the product itself and must therefore work to create added value to the product.The purpose of this thesis is to carry out a study on consumer decision-making when purchasing homogeneous products, and to examine how companies work to strengthen their brand and gain market share in a homogeneous product market. The market that this thesis highlights is the coffee market.To answer the purpose of this thesis the writers have conducted a questionnaire survey regarding consumers? decision-making process and interviewed two marketing managers for two major actors on the coffee market.

Background: As companies are operating in more globally and complex environments, the need for risk control is accelerating. In an ever-changing environment, companies cannot merely focus on traditional risks, which include financial and insurable risks. To maintain competitiveness, companies need to extend their risk management to include all risks, traditional as well as operational and strategic risks. Purpose: The purpose is to describe and position risk management for Telecom operators, in comparison with the risk management literature, with regards to structure, processes, learning process, visions and benefits. In addition, our aim is to link risk management perspectives with the different strategies for knowledge management.

As a result of increased property prices on apartment buildings in Halmstad many local investors thinks that the market behaves illogical. This because these investors can?t find any profitability in many real estate transactions. The valuation between different investors on the same object therefore goes their separate ways. One example of this is a property in central Halmstad which starting price was about 23 million SEK.

Investor Relations is a function used by companies to compete for capital by creating relations with investors. It is a young function, earlier practiced by the same people who had responsible for exercising the Public Relations.Investor Relations has evolved a great deal lately but there are still no concrete theories behind the function. The aim though is clear and there are literature explaining how to practice the different parts. The most research within Investor Relations uses the theory of Relationship Marketing. Lately the two authors Hägg and Preiholt have started to examine what they call Financial Marketing since Investor Relations is about relations between actors on financial markets primarily.In this paper, we examine the aspect of information in Investor Relations.

This thesis is using the theory of participatory democracy to show how one can work to increase the participation in the society, between elections as well as during elections. For a couple of years now many traditional democratic countries have been struggling with low voting rates. Hence this, I find it interesting to study what has been done to cope with this problem. The government in Sweden had a project working on how to make more people involved in the democratic process, especially people that to a lesser extent participate in this process. In this thesis two projects will be studied, Möllevångsgruppen and Unga väljer Miljö i Malmö.

Handling product returns has become a critical activity for organizations as the volume of gods flowing back through the supply chain rapidly increases. Few research studies have published specific empirical data concerning the reverse logistics practices of companies. Information technology and information support has long been recognized as a competitive weapon ? capable of enhancing company performance and achieving efficient reverse logistics. Reverse logistics is very unlike the forward, as it is more reactive and also has less visibility.

Problem discussion: Long-term supplier relationships have become more common. Hence, supplier evaluation is a critical activity for many companies. However, making a relevant supplier evaluation is time consuming. Therefore, it is important to decide which of the suppliers to put an extra effort on. Should all suppliers be evaluated in the same way? Previous, focus has been on purchasing of direct material.

As the environmental awarenesshas increasedin recent decadessohas the society?s demand forenvironmentalresponsible companies(Ammenberg, 2004).One way for companies to take responsibility and work with environmental issues is to implement anenvironmental management system(EMS). EMSserves as a tool for companies to systematically work with environmental issues and develop the company's environmental efforts. ISO 14001 is theEMSaccording to whichthat the majority of companies today choose to get certified(Brorson & Almgren, 2007). The introduction and operation of the ISO 14001 requires significant financial and human resources and it can therefore be questioned whether the environmental managementsystem is adaptable forall companysizes.The purpose of this studyis to examine whether EMScan provide environmental and economic benefits for companies of all sizes and ifthe conditions to get certifiedaccordingto ISO 14001 is the same for large and smallcompanies.A literature study was made to collect information on company'simplementation of ISO 14001.

The purpose of this paper is to examine and analyze past development of mutual funds in large and small mutual fund companies and see if there are any differences between these two segments. Limitations on the number of funds have been made by choosing Nordic mutual fund companies that invest in emerging markets over an 11-year period. The study is made on 66 mutual funds managed by 13 mutual fund companies in which the segment of small fund companies includes seven fund companies with assets under management less than 100 billion SEK and the segment of large mutual fund companies includes six fund companies with assets under management more than 400 billion SEK. In the comparison of the segments the Sharpe ratio has been used to calculate the risk-adjusted return. The study shows small differences of the risk-adjusted return between the segments.
