Enklare korglutning

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

Strindbergsbilden idag : En analys av åtta litteraturhistorier för gymnasiet

The purpose of this study has been to analyze the image of Strindberg in today's upper secondary school. How is the author portrayed in the textbooks and teaching aids, and which parts of the authorship does the textbook and teaching aids authors choose to focus on?  This work has been implemented in the form of a textbook and teaching aids survey where eight textbooks for the upper secondary school from 1989 to 2008 has been analyzed with focus on the sections that consider Strindberg and his authorships.What emerges when studying these textbooks and teaching aids is that they give a rather synonymous picture of the man and the author Strindberg. Big focus is aimed on private life and the scandals that the author more or less voluntary became a part of. The majority of the textbooks treats matters as ?the misogynist? and ? the critic of society? and the so called Inferno crisis, and also when one discusses the literary works it is done in the light of the author's own life and accomplishments.When it comes to the author's literary production it is a very limited selection that is presented to the students.

Det ryska barnbibliotekets roll och överlevnad i dagens Ryssland : En fältundersökning på barnbiblioteket i Pskov

In an international perspective the Russian children s library is a unique institution, being solely committed to children up to 14 years of age. In Russia of today it is, however, being exposed to hard pressure as the economical and social conditions have changed dramatically since the collapse of the USSR. My interest lies in examining this change of living conditions for the children s libraries and how this in turn affect their work and role in the present state. In order to view this change in a longer perspective, I compare the situation for children s libraries during the time of communist regime with that of today using documents about and from children s libraries. I have studied its legal position and conditions, financial and political state, and how the modern society affects children and youth, especially their daily cultural life.

Det nazistiska hotet i Tidens spegel 1932-1939 : Arbetarrörelsen i spänningsfältet mellan demokrati och diktatur

The purpose of this study is to examine the effect the Nazi threat had on the swedish labour movement between 1932 and 1939 and to enrich what kind of pre-understanding they had about the fall of the Weimar Republic and the upcoming and effects of the Third Reich.Brought by the development in Germany, a debate and struggle took place in the Social Democratic journal Tiden over the meaning of concepts and there ability, in the hands of demagogs, to overthrow democratic structures. The concept of socialism and its concepts attribute play a major part in this investigation. By establishing fields of tension such as - nation vs internationalism, socialism in theory and in practice, political democracy vs evolved democracy and the diverse principles of neutrality, the first principle meaning the defending of national boarders, the other meaning not only defending your own country but taking an active part in defending democracy in the world - I was able to observe the movement and change of concepts within this fields. The result showing that the concept of socialism and near related attributes, in the hands of national socialists had undertaken a wast change of meaning, which applied in the Swedish debate threatened to undermine the power and force of the Social Democrats applied in the political discourse in Sweden. To defend itself and strengthening the Social Democratic hegemony as well as maintaining the goal of evolved democratic expansion, they were forced to win the confidence and votes of the middle class.

Kina i Afrika : En studie av Kinas afrikapolicy

Since the beginning of the new millennium, China has opened itself to the outside world and in an enormous pace increased its contacts and relationships with other countries. The trigger to these dramatic changes of economic and foreign policies is the insight that China can no longer sustain its rapid economic growth, largely based on industrial production, on energy and raw materials from China alone.Good relations with African countries have been of highest priority in China?s strategy of ?Going global?. The new African policy is based on the two principles of mutual benefit and non-interference in internal affairs ? as opposite to the West?s strategy of structural adjustment programmes (SAP), which include massive interference in internal affairs.

Femtio Nyanser av Co-branding - En kvantitativ studie om effekterna av co-branding på konsumenters varumärkes- och produktutvärdering beroende av kvalitetssegment och hedoniska shoppingmotivationer

The retailing industry has an extremely high density of brands. In order to differentiate its offer, both retailers and suppliers, are constantly forced to come up with new ways to launch their products. A collaborative strategy between two brands is called co-branding, which means that both the private label and the supplier's brand are displayed on the new product packaging. Several studies have shown that a co-branding strategy is successful, but many operators are still reluctant to use co-branding in fear of long-term losses due to potentially damaged business relations. The objective of this study is to explain how the product- and brand related value for customers, retailers and suppliers is affected by co-branding between private labels and national brands.

Medlemmarnas syn på lantbrukskooperativa företag : en jämförelse mellan föreningar av olika storlek

During the last decade several cooperatives have struggled against many problems. Especiallyin North America several cooperatives have been forced to reconstruct, merge or have beenpurchased by other firms. There are many reasons behind these problems, but one observationmade on these cooperatives implies that they have one thing in common. The cooperatives areall very large and have a complex business structure.Lantmännen is one of the largest cooperatives in the Nordic Countries with its main office inSweden. In Nilsson et al.

Agricultural and forestry business owners? perceptions of banks

Over the course of the past the agricultural sector has been characterized by radical market changes. Changing market conditions have forced owners of agricultural and forestry businesses to make further investments. This increase in investments has led to a greater need for external capital, which has increased the relationship between banks and owners of agricultural and forestry businesses. The financial sector is characterized by strong rivalry, which forces banks to create strategic positions in the financial market. Since agricultural and forestry businesses are generally seen as secure customers by banks, due to high property and land values, the competition between banks with agricultural and forestry businesses as customers has amplified.

Förbehandlingstekniker och LCA för rötning av organiskt avfall : Modellkonstruktion och Utvärdering med ORWARE

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

BIM i produktionen vid väg- och anläggningsprojekt

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

?Jag jobbar som polis men jag brukar inte säga att jag är en polis? : En kvalitativ studie om polisyrkets påverkan på den enskilde individen med fokus på roller samt emotioner

The purpose of this study is to gain a better understanding about the police profession's impact on the singular individual, with a focus on roles, regions and emotions. The main question is to understand if and then so, how individuals outside of work will be affected of the profession and professional events. In order to answer this question I carried out six semi-structured in-depth interviews with police officers who worked at the main office in a police region in a midsize city in Sweden. To ensure reliability and allow readers to conduct their own assessments the quotations in this study are anonymous. The analysis of the collected material is based on selected parts of Goffman's theories about dramaturgical perspective as well as selected emotion theories.
