This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.

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..

To become old and live in an institution could mean that the habits and routines they have obtained during their lifetime and are used to may become changed. There are fixed norms and rules which the elderly more or less have to adjust to. The aim of this study was to describe how nursing staff attitudes influence on elderly care takers meal situation. The method of this study was a literature review. The result showed that norms and rules not always are adjusted to caretakers? wishes and needs.

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.

Matsvinn förekommer i hela livsmedelssystemet och har en negativ påverkan på både miljö och samhällsekonomi. Miljökostnaden för varje kilo matsvinn blir högre ju mer förädlad varan är. Denna studie har utförts på uppdrag av Regionservice Måltid inom Västra Götalandsregionen. Syftet är att identifiera vårdspersonalens uppfattningar om bakomliggande orsaker till orörda matbrickor på två sjukhus i avsikt att belysa möjliga förbättringsåtgärder. Frågeställningarna är: Vilka rutiner har medarbetarna på respektive avdelning kring beställning av matbrickor? Hur sker beställning och avbeställning av matbrickor på respektive sjukhus? Vad är grundorsaken till orörda matbrickor? Vad kan avdelningarna respektive köket göra för att minska antalet orörda brickor? I studien används en kvalitativ metod där empiriska underlag bygger på intervjuer och kortare observationer.

The subject of this thesis is studying how physical libraryenvironments express ideas on the function of the library, asstated in guiding documents. The ?physical library? isdefined as everything inside the library building, andexcludes the library architecture, focusing on things likefurniture, furnishing and the arrangement of physical media.The two questions asked in this thesis are: What aspects ofthe idea of a public library?s function, as expressed in theguiding documents of the library, are possible to study in thephysical library environment? In what ways can theseaspects be studied in the physical library environment?The study of the thesis is divided into two parts, a ?prestudy?and a ?main study?. In the pre-study aspects areidentified by reading guiding documents from differentpublic libraries, and analysing the result together withprevious studies on physical library environments. In themain study three Swedish public libraries (located inHelsingborg, Åstorp and Klippan) are visited, and theirenvironments are studied based on theory on what items andmeans of expression can influence the experience of thelibrary function.The four aspects that are identified in the pre-study areculture, education, accessibility, and development.According to the results of the main study, culture isexpressed in the library environment through aesthetics,education through the environment being inviting andstimulating for studies, accessibility by the environmentbeing inviting, functional and democratic, and developmentby modernity.

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.

To give a realistic impression in a driving simulator for nighttime driving, there are many challenging aspects to consider. One of the most important aspects is the illumination caused by the headlights of the own vehicle. To give a realistic impression there is the need to consider the characteristics of the headlight in use to be able to represent main and dipped beam, but also to represent different models and types of headlights. Another important aspect is the dazzling effects caused by the light cast by other vehicles upon the driver. These effects are not only important to give a realistic and visually appealing simulation, but also to simulate blinding effects which may affect the drivers ability to perceive the traffic environment to a large degree.

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.
