Modellering av indunstning på Södra Cell Mönsterås
Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.
Empiriska växelkursmodeller för den svenska kronan - Är det någon som fungerar?
The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..
Olika fönster mot samma omvärld ? En undersökning av omvärldsbevakningen på Stockholms stadsbibliotek och Akademibokhandeln i Stockholm
The aim of this thesis is to explore how a bookstore chain and a public library meet the needs of their customers through environmental scanning. The empirical material is derived from six semi-structured interviews with six informants, three from each organization, together with an analysis of internal documents. The method used is a case study and the theoretical framework is based on models used in the process of environmental scanning, as described by Choo, Hamrefors and Hedin & Sandström among others, and which facilitate a comparison of the environmental scanning of the two organizations. The results of the study indicate that the library, as a public organization with a mission in society, perceives the environment as society as a whole and all its members as their users, whereas the bookstore concentrates on the sectors of the environment that affect their sales. The consequences of these different views are that the library is more active in the environment and uses surveys as a basic source of information, while the bookstore is more passive, and relies on statistics for information.
Aktiv marknad: Nivåer av verklighet: - En fallstudie på svensk storbanks tillämpning av IFRS 7 och IAS 39, med avseende på fördelningen av finansiella tillgångar i level 1 och level 2
This essay examines the process of fair value accounting of financial assets in a Swedish commercial bank, in contrast to the theoretical approach stated by IASB. The theoretical background contains a review of the academic standpoint on fair value accounting and historical cost accounting, a detailed description of fair value accounting according to current and future IASB regulation and on the American FAS 157 regulation. The empirical case study describes the process of valuing and classifying financial assets into level 1 and level 2 of the fair value hierarchy. The analysis describes how the legal requirements for classification are interpreted and applied in practice when valuing bonds and derivatives. The authors provide an explanation as to why the majority of financial assets are valued mark to model rather than mark to market as well as a suggestion on how the share of market valued assets can be increased..
Modell för dimensionering av AGV-system inom tung industri
Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.
Som om min kropp inte är min...: Bilden av unga kvinnors sexualitet i svensk ungdomslitteratur
The purpose of this Masters thesis is to examine how young womens sexuality is described in Swedish youth novels. The analysis is based upon eight books of which four were published during the period from 1970 to 1975 and four books were published during 2000 to 2005. The theoretical framework is based on a gender theoretical perspective where Yvonne Hirdmans theories about a gender system and Ylva Elwin-Nowaks and Heléne Thomssons ideas about gender construction are crucial. Also Anthony Giddens theories about sexuality in the late modern society are used, where the plastic sexuality and the pure relationship are central ideas. The method is based upon textual analysis, and a model of analysis is constructed with its basis in the theoretical attempt.

Kosovo - Självständighetens betydelse och möjligheter : En fallstudie i demokratiutveckling
The aim of this study is to examine the democratization process of Kosovo in the years after the countries independence was assured. Two central questions for the case study consist of whether a democratic improvement in the country has occurred and which factors, positive and negative, are present to further improve or impede the democratizationprocess. The study builds upon two central definitions, democratic states and democratization in order to gain theoretical background to be able to measure these two quite abstract expressions. A socioeconomic model is used to measure favorable or negative developments within Kosovos society and the findings of this model confirms the hypothesis of modernization theory, namely that increased socioeconomic development increases the chance of a positive democratizationprocess. There has been a positive democratic development aswell as socioecomic progress but since the nature of this study is merely descriptive and not explanatory, it doesnt make claims on the explanatory power of modernization theory.
Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt
This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.
Modellering av en panna med rörlig rost :
The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.
Radioräckviddsberäkningar för flygande plattformar
There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.
Adaptiv katalysatormodell för reglering
This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.
Utmattningsdepression : En studie om det moderna arbetslivets relation till psykisk ohälsa utifrån fem kvalitativa intervjuer
The purpose of this essay is to try to understand the relationship between the structures of modern working life and the development of burnout. By using the method of qualitative interviews we wanted to see if the Effort-Reward Imbalance Model could be applied to the data we had collected. Two questions have been highlighted in our research: ? Is it possible to establish a relationship between the structures of modern working life and the development of burnout among the subjects interviewed? ? Is it possible to explain the development of burnout among our interviewed subjects through the Effort-Reward Imbalance Model? Our theoretical frames are the general theories of the modern society and the modern working life as developed by Anthony Giddens, Ulrich Beck and Zygmunt Bauman. We have also used Johannes Siegrist?s medical-sociological Effort-Reward Imbalance Model (ERI-Model).
