Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

In this essay we aim at finding an appropriate flash estimator of the quarterly Swedish private consumption (PK). With the aid of the statistics program TRAMO we study if monthly data from the consumer survey (HIP) and retail industry (DH) can be used in a transfer function model (TFM) to forecast PK. In the work of assessing the state of the market and the business trend, fast information from the national accounts is needed for making decisions for the economic politics in Sweden. A way to speed up the information process is to use leading economic indicators to asses this development. Another way to get information faster is to use a flash estimate.

AbstractThe purpose of this thesis is to analyse the basis of Russian diplomacy, and by doing that develop the analytical instruments available, in order to improve the comprehension between the parties in negotiations. Descriptions of the national characteristics of Soviet and Russian diplomacy are made by an analysis of memoairs and other examinations of their negotiating behaviour. To ensure the result of the characteristics two case studies of the non-nuclear proliferation negotiations are made, followed by a comparation between the Soviet and Russian diplomacy. From these results, I analyse the groundworks of russian diplomacy, using three theories about how ideology, national identity and prevailing self-image can affect the national negotiating behaviour. The results show that there have been changes in only some parts of the negotiating behaviour and that there is a need for all three theories to explain different parts of the complex system of Russian diplomacy which is based on the plurality of culture, ideology, language, ideology and history..

The purpose with this essay is to study police students perception of men?s and women?s role taking and behavior in a group. The question that is presented is if a group?s efficiency can depend on which gender the members of the group have. There are many theories about the concept male and female and the meaning of these words.

The purpose of this study is to examine and explain why three Swedish public libraries failedin their ambition to act as information services for small and medium-sized firms (SMF). To support this purpose two major assumptions are made:1) Public libraries who plan to run this kind of "business" must act with the same means as "professional" services.2) The service must be adjusted to the information needs of the customer.Based on these assumptions sixteen factors which are crucial to the "success" for this kind of service are presented.Applied to the information services of Lidkoping, Sölvesborg and Västervik, these factors reveal a number of shortcomings and mistakes made by the libraries.To understand this result these information services are seen as parts of a traditional Swedish public "library-thought". It is shown that, fundamental ideas in the way the public libraries are defined, like the responsibility to act in a neutral and democratic way, also characterised the three information services.These ideas together with the opinion of SMF as a "rational" information-consumer resulted in information services who did not meet the information-needs and information-behaviour of SMF..

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.

Lameness from the carpus is not unusual in the horse. Multiple soft tissue structures such as tendons, ligaments, the joint capsule and synovial structures can be the originating source. All these structures can be examined with ultrasound, although a description of a systematic examination method is lacking. That is ? which structures, what they look like in an ultrasound examination, how to look at them in the best way, and in what order.

The purpose of this essay was to in a specific project for unemployed youths between 18 and 24 years, from an ecological point of view, examine how the youths experienced their unemployment and also to compare the purpose and structure of the project with the participants' experience.Important questions in my essay were how the unemployment affected the youths' identity and social circumstances, if the participants found the project meaningful, and experienced that they could influence how the project was formed, if the purpose of the project was in accordance with the youths' experience and how the ecological perspective could be used to understand the situation of the youths.To answer these questions one interview was made with one of the employees and five interviews were made with participant youths.The results of the essay was that the youths' experience of the project were very much individual. All of the participants found something in the project meaningful and most of them thought that it was possible to influence the project in some way. Something that both the youths and the employee pointed out as important was the employees and their supporting role..

ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.

The aim of this essay is to do a queer reading of the early Swedish pentecostal movement, with a special focus on the women within the movement. The main empirical material is Gustaf Emil Söderholms Den svenska pingstväckelsens historia part I and II, published 1927 and 1928, in addition to this a selection of articles from the Swedish pentecostal magazine Evangelii Härold has been used. The theoretical framework consists of Judith Butler's concepts of heterosexual matrix and performativity, as well as interpellation, and of Adrienne Rich's concept of a lesbian continuum. The analysis shows that the evangelist role, as well as the charismatic practices of the movement, made it possible for women to take the position as leader and teacher of congregations, and thereby take up a male subject position. The role as evangelist also made possible a life outside of the heterosexual norm, within the lesbian continuum..

The goal with my project was to explore what it is that distinguishes Berlin as a city and then translate that into abstract patterns. The patterns are made for wallpaper and are presented in a book as a collection.After spending six months almost constantly abroad visiting many different citys I began to wonder what it is that makes a city unique. Sometimes it feels as though cities are reduced to the sum of their famous sights. But of course a city is more than that. It?s the people who live in it, the history, architecture and culture.

When it comes to investigating the motives behind activism, the members of political study have a lot to say. I aimed to critiqually rewiev this in my thesis. I asked the question ?What do the actor themselves claim lay behin their decision to become motivated?? To highlight this complex dilemma, I sought to discuss new social movement theory by comparing it to reality. This includes a literate examination on contemporary political science approaches, and a study of two organisations in the south of Sweden, choosen not to despise any excisting theory, but to give it a sense of reality.

During the late twentieth century, political and societal changes gave rise to an increased interest in performance evaluation in public organizations. This development also affected libraries in the public sector. The main concern for this master thesis is performance measurement in libraries. In this study two different types of libraries are investigated, one public and the other academic. My aim is to find out if and how performance measurement appears in the libraries annual activity reports.

We can see an increasing middle age population in large parts of the world. People are healthier when they retire than they were before. As people grow older, physical and mental changes occur that can make the use of cars more complicated. The possibility to travel by car is important for many people to keep the connection with the society and to feel independent. How can Volvo cars face the needs of this growing target group?The purpose of this project is to make a car concept that responds to those needs, it is therefore important to maintain the values of Volvo cars.

An inquiring study of literature has been conducted, about the human colour perception (theimpression of colours). The colour has been examined, both as conscious and subconscious signal,and reasons for it?s influence have been exammed.The practical parts of the degree project have been carried out in active collaboration with thecustomer, The Association Hedemora Assistansservice (HASS), which offers handicapped persons astimulating spare time by personal assistance. A graphical profile-programme and an informationfolderhave been produced, easy received by both handicapped (with defective vision) and normallysighted persons. The graphical profile-programme was made in collaboration with the customer.Concerning the information-folder HASS took the main responsibility for the choice of photographswhile layout, text writing, colour-reproduction, original-production and connecting printing workswere made independently.
