Genom litteraturstudier samt praktiskt arbete med förbättringar av programvaran File Secure har ett antal lämpliga designmönster för konfigurationshantering i Java identifierats och applicerats. Den typ av konfigurationshantering som här avses innefattar inläsning från en databas till en objektrepresentation, samt ett grafiskt gränssnitt som låter användaren modifiera datat. Det antas att mängden data är förhållandevis liten, vilket har gett upphov till vissa förenklingar. Resultatet av arbetet presenteras i form av ett mönsterspråk för konfigurationshantering, innefattande designmönstren Domain Model, Active Record och det befintliga mönsterspråket Model - View - Controller. Detta kan appliceras i många olika sorters system..

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

Developed model for easier animal welfare assessment- with examples from dairy cows in loose housingAnimals in captivity are completely dependent on human care. If captive animals are prevented from exhibiting their natural behavior, they may suffer. Animal welfare inspectors, who insure that the animal welfare legislation is followed, use a checklist to assess the situation in the husbandry. This checklist contains only two levels of assessment, which may result in a lack of detail in the assessment of the husbandry. The objective of this report was to develop a more detailed model that provides an overview of the situation in husbandry.

Due to the forest industry downsizing, many communities in rural forest regions in Canada and Sweden are facing problems to survive. In order to create community sustainability, resilience and well-being in remote forest regions, the view on the forest resources has shifted towards multiple use, through the concept of sustainable forest management (SFM). Beside the economic and ecological elements of sustainability, the social forest values are needed, contributing to the human well-being, local participation, stakeholder collaboration, human rights and cultural connection. In this thesis the embodiment of the social component of SFM within Prince Albert Model Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners and facing similar challenges as rural boreal forest regions, the two model forests are compared through analysis of projects and activities, conducted interviews and organization documents. Looking at projects mentioned as successful by the interviewees, they all have elements from the social values of SFM. The direction can be explained by the introduction of the Forest Communities Program in Canada, demanding the Model Forests to work towards community stability and resilience, the Model Forest organization concept itself and the way global focus are increasing around social forest values. In the future, it may be important that the role of the MFs enable some kind of political authorization and legitimacy in order to improve conflict solving and indigenous rights equality.

Making accurate predictions of private consumption expenditures is a difficult task. This thesis examines if consumer confidence can be used to forecast consumption. Using regression analysis, the link between consumer confidence and private consumption expenditures is analyzed for Sweden between the years 1994 and 2005. Two different models are estimated. In the first model consumption is regressed only on consumer confidence, while model two is extended to contain more variables.

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

The furniture retail industry in Sweden has gone trough large changes during the last decades. Today the industry is tough and in the maturity stage where few new companies enter, especially if they do not have a unique offer. The furniture companies have become larger and fewer, the changes have lead to difficulties for smaller and medium sized companies to grow and be profitable.Our purpose is to analyse, evaluate and compare three smaller companies in Stockholm with the intention to find what kind of marketing strategies they are using to survive on the Swedish market. First we interviewed the three companies to see what they do to survive on the market, then we asked 100 persons to fill in a questionnaire to see if they had the same opinion as the companies described.With help from theories we prepared questions which laid the foundation to the empirical part of the essay.The result from this study shows that the three companies differ from each other when it comes to using relationship marketing and placing the customer in the centre. All of them are aware of the importance of doing so, but because of different limits and possibilities they can not fully adjust everything to the customer.

This paper is the result of a study of competition and cooperation in regard to tourism between the five largest municipalities in Norrland in northern Sweden. The municipalities are Luleå, Skellefteå, Umeå, Sundsvall and Gävle. The aim was to study the relation between competition and cooperation between these municipalities. An important theoretical aspect in this study is coopetition, where competition and cooperation occur at the same time. The studies on coopetition in the Nordic kontext is limited and the main literature on coopetition study the relationship between firms. This study however takes a geographical standpoint and aims to fill the gap in the literature on how competition and cooperation are connected to each other between chosen municipalities. To do this the tourism strategies of the municipalities were studied thoroughly. These written strategies provided information about how the municipalities view their competitive advantages and disadvantages and some general information about how they cooperate with the nearest regions. To find out how the municipalities think about competition and cooperation with the other four specific municipalities interviews were made with experts on the tourism field in each municipality. The results show that the municipalities do not have established strategies for how they are to be competitive compared with other specific municipalities. They do not see it as profitable to compete, instead they should complement each other. At the same time however, most of the municipalities mostly cooperate with municipalities in a short distance from them, and due to lack of resources only briefly or not at all with the municipalities studied here..

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

In the thesis we have shown that it is possible with current technology, to buildneighborhoods that are largely self-sufficient. We have obtained some information aboutongoing work in the field of energy efficient buildings and active house which we have usedto develop a model. The feasibility study for Ranagård we have e.g been forced tofollow laws on groundwater covered, resulting in the construction of basements for singlefamilyhome is not possible. The model that we have built up overtime has been the central part of the work. The model illustrates very well what an activehouse neighborhood means and potential of such an area.

Mergers between companies has become more and more common in Sweden and in the rest of the world with the motive to increase the competitive strength in the current markets and has an important role within organisational development of companies. When organisations merger there is not only buildings and objects that are put together but also their individual organisational structures, people, values and cultures. This can be a difficult process and can affect many people in how they think conscious as well as unconscious, feel and react.The purpose of this thesis is to gain a deeper understanding of how employees are affected following a merger when changes in the organisational culture come up, and how these changes are expressed.This thesis is delimited to investigate only one company, Skruf Snus AB and only focus on their business and employees in the region of Stockholm. The thesis contains a qualitative investigation with semi structured interviews that has been carried out with eight employees at Skruf Snus AB. The thesis is partly based on a model of Schein which describes the different levels in organisational culture and partly on some theories about reactions to change in relation to the integration between the employees following a merger.The results of the investigation indicate that with a merger the whole organisational culture is affected and therefore also the employees.

In a world where digital media is becoming a greater part of people?s everyday and working lives it is plausible to assume that the upcoming generation of pupils expect the teaching media to adapt thereafter. It is this assumption of an increased demand that Natur & Kultur is hoping to be able to meet. This thesis has been a stage in the process of producing digital material in the subject of mathematics for high school students. Specifically the aims of this thesis have been to make a rough description of the largest competitive companies? products within the same market, explore and put together a brief theoretical foundation of contemporary research and produce concrete examples of ideas for digital applications.

AbstractIn this thesis we aim to extend the current theories about a concept called persona. A persona is a model of a user, mostly based on qualitative research and made with such accuracy that it to some extent can be used as a replacement of a real user in a development process and as a communicative tool. We will present a way of constructing this persona without meeting the actual users and follow up with interviews from the organization using them. This will lead to a model over the process of introducing personas as a concept in an organization,previously not familiar with the concept. The model is adapted to also work for projects and organizations where the concept is already known..

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.
