Verksamheten ombord på fartyg blir mer beroende av datakommunikation och många av arbetsuppgifterna ombord underlättas genom att besättningen kan nå information lagrad på annan plats. Fartygens bredbandsanslutning sker till största delen via satellitkommunikation där långa avstånd och begränsad datahastighet resulterar i att datakommunikationen blir ineffektiv. I denna studie undersöks vilken prestandaförbättring som utrustning för nätverksoptimering kan innebära för långsamma WAN-förbindelser via satellit. Undersökningen visade att det största problemet med anslutningar via satellit är den signalfördröjning som uppkommer vid långa sändningsavstånd. Detta medför att det blir prestandaproblem för datatrafiken och användare upplever anslutningen som långsam.

The aim of this thesis is to discuss and analyse the American cotton subsidies? effect on the world market in general and developing countries in particular. The amount of U.S. subsidies is substantial compared to most other countries, but a great deal of the effect is due to the USA?s significant share of the market.

The aim of this master's thesis is to present an introduction to semiological analysis of web based material, which is a hypothesis that combines the theoretical framework of classical Saussurean semiology, visual social semiotics as was developed by Günther Kress and Theo van Leeuwen, and Roland Barthes's notion of 'Myths'. Furthermore, a new tool called 'pseudo-signifier', constructed solely for the thesis, is also used in conjunction with the semiological analysis. The hypothesis is tested in a case study involving the web portal of a Swedish commune, Gothenburg (goteborg.se). A complete semiological analysis is performed on the case. The case study revealed numerous findings of interest, among others that images and texts on the web portal were sometimes used in a contradicting manner, and often in a way that symbollically excluded citizens from the portal, a fact which could be uncovered when studying underlying myths that permeated the web portal.

The purpose of this thesis is to examine whether the concept of permanent establishment, as defined in Article 5 of the OECD Model Tax Convention on Income and Capital, is applicable to electronic commerce and if so whether the current definition is able to appropriately deal with the challenges of electronic commerce.In 2003, the OECD added a new section to the Commentary on the Model Tax Convention on Article 5. The new section is a clarification on the application of the permanent establishment definition in electronic commerce.The current definition of permanent establishment in the Model Tax Convention relies on the physical presence of a foreign corporation as the threshold for source taxation. While the current definition, prima facie, might be applicable on electronic commerce, the highly mobile nature of electronic commerce might affect the current revenue distribution equilibrium between states..

The need of knowledge revolving first-time father experiences, feelings and thoughts is extensive and insight and knowledge about his emotional life in conjunction with being a dad is equally important. The purpose with this study is to investigate how men, that recently became a first-time father, manages and experience the first time with his child. We used a narrative method and interviewed seven fathers as we conducted our qualitative interview study. All the fathers went through life changes. No one talked about sacrifices, but noted rather that their lives were to become different.

Background: Low Price-Earnings ratio, low Book-to market ratio and low stock prices can give the impression that a stock is ?cheap?. Is it through systematic use of these portfolio strategies possible to beat the market index ? in other words does financial illusions exist? Purpose: To examine if the Stockholm Stock Exchange is an efficient market. Limitations: The efficiency is tested solely through the chosen portfolio strategies: low Price-Earnings ratio, low Book-to-market ratio and low stock prices.

The aim of this study was to determine a method to habituate treadmill-naive Labrador Retrievers to walk and trot on a treadmill. 17 Labradors was equipped with reflective markers glued to the skin. Their motions were captured with six 240 Hz infra-red cameras as they walked and trotted on a treadmill three times a day for two days. Also the heart-rate was recorded. We then used QTM and custom built software to analyze the measurements.

In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

The purpose of this Master?s thesis is to investigate how diversity takes shape in children?s picture books published in Sweden. Twelve picture books, which touch the aspect of diversity in the categories of gender, ages, culture, nation, ethnicities, language, class, sexuality and functional disorder, were chosen from the Swedish National Council for Cultural Affairs catalogue for youth and children?s books 2006. They have been analysed with the conception of ikonotext and with the theory of Pierre Macherey?s image in the mirror, of how literature reflects the reality of society.

By describing and analyzing a self made composition for the Swedish folk music instrument ?nyckelharpa? with emphasis on playing techique, dissonance treatment and interpretation questions are reflected upon regarding how dissonances and andvanced harmonical progressions are treated on a limited instrument such as ?nyckelharpa?. By emphasizing the traditional norm connected to the interpretation and instrumentation of traditional Swedish folk music (a traditon in which the nyckelharpa is included) and comparing the te- chniques connected to it with the recent composed material in a western classical context the possibilities and limitations in composition and interpretation are further investigated. Thus the musical experience and the documentation of the process of composing a concert for nyckelharpa provides a knowledge base for reflective analysis upon questions regarding interpretation, composition and dissonance treatment. This thesis also provides a brief summary of traditional playing and bowing technique as well as a short historical description of the Swedish traditional instrument ?nyckelharpa?..

About a year ago, Göteborgs-Posten, one of Sweden's largest daily newspapers, decided it was unprofitable to continue producing their feature-style weekend magazine, Två Dagar. Standing at a crossroads,not wanting to stop producing the weekend magazine altogether, they decided to outsource. Spoon Publishing AB, a content agency with strong ties to Göteborg, were assigned with taking over the production.Going forward, Spoon has taken over a majority of the responsibility for the conceptual work and actual production, all with the main purpose of reducing cost and increasing efficiency.Normally Spoon does content marketing for a wide range of customers in an equally wide spectra of channels, from print to radio, television and web.The main purpose of this essay has been to investigate and establish whether the journalistic integrity and quality has in fact been maintained despite the weekend magazine being outsourced. We have analyzed selected editions of the magazine, first and foremost inarticles under the vignette fashion, using a qualitative method for content analysis, scrutinizing everything from the denotation of single words to the big picture. This specific vignette contains the most frequent contributions by in-house, or at least reappearing, journalists.Perusing the material in Två Dagar, we have come to the conclusion that the magazine has indeed retained its level of quality and still reflects the same core values as before being outsourced..

The aim of this master?s project is to explore ways to perform piano music conceived dramatically. I do this through performance of Beethoven?s Appassionata Op. 57 and of Scriabin?s Piano sonata no.

The bark from prehistory ? an osteological analysis on dog bones from the Stone Age settlements of Hemmor and Gullrum at Gotland and a theoretic study of the secular and sacred roles of the dog during the Neolithic.Dog bones from two Pitted Ware Culture (around 2500 BC) settlements, Hemmor in När parish and Gullrum in Näs parish/Havdhem parish, at southern Gotland, Sweden are analyzed. The analysis contains a study of age, withers height and size estimation as well as skeletal changes and pathologies. The attempt of the analysis is to highlight the secular and sacred role of the dog during the Neolithic at Gotland. The dog bones were collected during excavations in the years 1890 and 1903 and were found across the entire surfaces of the settlements.Although there were no specific dog breeds during the Stone Age, the dogs at Hemmor and Gullrum show a wide range of size (withers height spans from 39,74 cm to 56,47 cm) and may therefore have been used for different purposes depending on their size.
