This Master Thesis covers the concept of Green Cars. The background to the research area is the high and rapidly growing number of cars, which together with other factors ad to the pollution of the environment. Under the Kyoto agreement the signing members agreed to lower the emissions of green house gases, further on the EU has a 3-pillar strategy on carbon dioxide and cars. Included in the EU strategy is a voluntary commitment from the car industry to reduce carbon dioxide emissions from new cars. The easiest way of lowering the emissions is by using alternative fuels and engines.

The object of this thesis is to discuss the limits of the hypertext concept. The issue is whether the concept of hypertext necessarily depends on the conditions of the electronic media and www, or if the concept of hypertext more likely is founded on certain textual structures and strategies. In the light of contributions to hypertext theory during the 1990s, this thesis compares different views on hypertext, and concludes with an evaluation. The poem it the authors own translation of the original Danish title det, written in 1969 by the system-poet Inger Christensen, is the object of this case study. The poem is analysed with respect to its structural organisation and literary composition.

Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

The paper contains comment, clarification and criticism, even constructive criticism, of some theses that have been put forward by Laurence Bonjour in his In Defense of Pure Reason.It presents a concept of experience that deals with the relation between cognizer and object of experience that has a great similarity to that of Bonjour. Through analysis it is shown that the concept of a priori entails that Bonjour has two concepts of a priori, a narrow and a broad one. The narrow one is, in my own words: According to moderate rationalism a proposition p is a priori justified if and only if you apprehend that p must be true in every possible world. This doesn?t mean that Bonjour doesn?t believe in an epistemological, metaphysical and semantic realm.

This project includes development of new packaging for dry spices and an investigation of how to automate the production line. The preliminary investigations show needs of an environmental friendly packaging possible to re-close. After screening for suitable materials three concepts were developed, a stand-up pouch, a plastic jar and a metal can. The pouch was excluded in a concept choosing process. In this process it was also decided to further develop the metal can concept.

The global market is becoming increasingly integrated and to keep up with growing competition and to achieve even greater success, companies expand to foreign markets. Previous studies have shown that the concept of psychic distance has an important impact on international performance regarding small and medium-sized enterprises (SME). The aim of our study is to provide the reader with a deeper understanding of how psychic distance influences export performance regarding Swedish SMEs. Through a single case study of a Swedish SME, we chose to research three different markets in three different continents. Our findings show that psychic distance influences export performance through export marketing strategy and active learning.

This essay set out to propose a problematic interpretation of the socio-cultural perspective on learning. Its purpose is to show how the socio-cultural perspective on learning defines the concept of knowledge in an incomplete way. The aim becomes then that of giving a more comprehensive description of this concept, and, to this end, to construct a new, broader pedagogic discourse. The investigation starts with a deconstructive analysis of Roger Säljö?s socio-cultural text in order to point out the incompleteness of the concept of knowledge.

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.

AbstractThere is a lot of confusion when it comes to defining Special Education. An example of this appears here by a statement from Assarson (2007) "Special Education initiates a special pedagogy, but contains no innate sense of what is the special component in it" (p. 52, authors? translation). This study is an attempt to clarify the elements of the concept.

In a society where adults set the conditions for children?s play and generate modern and at times technically advanced products, fundamental characteristics like simplicity, opportunities for motor skills training and learning tend to be neglected. Owing to this, the Linköping-based company Time In wants to introduce a new multifunctional product, which differs from other products in shape and function and lives up to the often overlooked, basic characteristics in a toy.With Time In as the assigner, the purpose of this master thesis has been to use simple means to produce a "learning by playing" concept. Since Time In sells toys and products suitable for children in nurseries and preschools, the development of the products has therefore included a study of nursery and preschool environments.The thesis has been carried out within the Product Design subject area at the Department of Management and Engineering at Linköping University. Concept development has been done in three phases: the Preparation phase, the Design phase and the Presentation phase.

Within the framework of the concept of Network Based Defence (NBF) services should be available in the network, in order to increase the aggregate capacity. A common situation picture is one of these services.The aim of this paper is to answer the problem "What are the main problem areas in the creation of a situation picture in the land arena, with the help of the technical sensors that exist today?" and to develop a basis for continued research in the field situation in the concept Networking Enabled Command, Control and Collaboration (NEC3) at JCDEC (Joint Concept Development and Experimentation Centre). To answer the problem, a descriptive method is to be used in descriptions of the land arena, the information arena and the sensors and a deductive method is used when analyzing the asensors in the land arena.The problems that exist in the creation of a common situation picture, is that different types of obstacles makes it difficult for the sensors, the large number of people who are not combatants and that it is difficult to judge if a civilian vehicle is a threat, then it could be driven by civilians or by combatants..

The aim of the essay is to investigate how the term ?Third world? is constructed in media. With this I intend to make a historical survey of the conception. With the help of Swedish newspapers and their description of the concept, I am going to answer the following questions: How is the concept ?Third world? constructed in script, in a historical context and in modern time? Is there a tendency of racism in the term?The method I used was discourse analysis.

The aim of this study is to discuss the implementation of Swedish integration policy from the perspective that public officials, so called front-line bureaucrats, are the real creators of this policy. The concept of integration is far from unambigous; it can have different meanings depending on the theoretical perspective applied. This give topical interest to the question of how the concept is conceived on the national level versus the implementation level. I also aim to uncover how these front-line bureaucrats look upon their role as creators of integration policy. My material consists mainly of interviews with front-line bureauctrats.
