Penumbra Suecica : Den negativa fo?reningsfriheten i Sverige mo?ter Margin of appreciation

This paper discusses if Margin of Appreciation is compatible with the idea of universal human rights. Through the case of Negative freedom of association in Sweden, it studies the phenomenon that Giorgio Agamben has called the State of exception.The questions that are discussed and answered are 1) How does the rights theories of Jack Donnelly and Ronald Dworkin relate to Margin of appreciation, and 2) How has Margin of appreciation been applied in cases concerning the negative freedom of association in Sweden, in the European court for human rights. These questions and answers are then used in the discussion on how Margin of appreciation affects the concept of universal human rights. .

Logikbaserade dokumentåtervinningsmodeller

The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

Öppenhet och kostnad för eget kapital: En studie på den svenska marknaden

Previous research has discussed how voluntary disclosure relates to the cost of equity capital. Theories of estimation risk support a negative association between disclosure and cost of equity capital, as empirically documented by Botosan (1997) among others. In this Bachelor thesis we investigate whether such a relationship exists on the Swedish capital market. Using the CAPM to estimate the cost of equity capital and a disclosure index based on Aktiespararen?s annual evaluation of corporate disclosure, we test a model where disclosure explains cost of equity capital.

Vilka möjligheter har barn till fysisk aktivitet i fritidshem? : En intervjustudie

This study is based on a statistical analysis of fundamental key ratios on the Stockholm Stock Exchange during the period 2004-2012. In total 35 financial ratios of 90 companies were tested, ultimately five ratios remained within the 5% significance level. These ratios were ROA, P/B, Total Yield, EV/EBIT and Operating Margin. A custom made investment model was created based on the purpose to achieve a risk-adjusted excess return. The results in general did not show any significant difference in return between the model's portfolio and index.

Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations

The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.

Rocchio, Ide, Okapi och BIM : En komparativ studie av fyra metoder för relevance feedback

This thesis compares four relevance feedback methods. The Rocchio and Ide dec-hi algorithms for the vector space model and the binary independence model and Okapi BM25 within the probabilistic framework. This is done in a custom-made Information Retrieval system utilizing a collection containing 131 896 LA-Times articles which is part of the TREC ad-hoc collection. The methods are compared on two grounds, using only the relevance information from the 20 highest ranked documents from an initial search and also by using all available relevance information. Although a significant effect of choice of method could be found on the first ground, post-hoc analysis could not determine any statistically significant differences between the methods where Rocchio, Ide dec-hi and Okapi BM25 performed equivalent.

Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

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).

Sinnesstämningens påverkan på det verbala flödet

Results from previous studies have showed that people with depression has an impaired verbal fluency. The aim of this study was to investigate whether individuals with depression also generate more words containing negative valence. Controlled Oral Word Association test were administered to a group of 13 mildly depressed individuals and a group of 20 non depressed individuals. The fluency and valence of the words produced was analyzed.The results showed no significant differences between the groups regarding either verbal fluency or negative valence. However, a significant positive relationship was found between a negative mood and negative valence.

Rekommendationer eller konversationer - Effekten av innehållet i word of mouth på mottagarens inställning till det omtalade företaget

We investigate the effects of various types of word-of-mouth (WOM) messages on consumer bahavior. The message is varied along two dimensions where one is valence and the other is whether or not it contains an explicit call for certain behavior or attitude change. We use an experiment in the form of a web-based survey. Five different scenarios were designed to represent neutral, positive, and negative WOM. The latter two came in two different versions - one with a recommendation and one without.

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.

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.

Att leva med bröstcancer. En litteraturstudie om kvinnors syn på bröstcancer och uppfattning om det sociala stödet

This study describes how the women lived with breast cancer. The purpose with this study was to describe the womens' view on the disease and the understanding they hade on the social support they were depended on. The method was a study of literature with article reviews according to Polit et al., 2001. As theoretical frame of reference we choose Carnevalis model, Everyday life -Functional state of health. The result showed that the following four groups were formed: Support, positive and negative support off nursing staff and significant others.

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.
