Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..

This two years master?s thesis is a review and exploration of the Swedish debate concerning children?s literature from the 19th century to the present, as well as the evaluation and analysis of four adaptations of the tale Red Riding Hood. The aims are to identify how ideas and values regarding the role of children?s literature in society have developed over time and to contribute with a knowledge base for continued reflection and discussion on the subject of children?s reading and mediation of children?s literature in public libraries.The theory and method used in the thesis, is primarily based on the discourse analysis of Michel Foucault. I have identified four main discourses: the educational discourse, the liberation discourse, the politicized dis- course and the popular discourse.

I denna uppsats skattas IS-kurvor för Sverige med förändringen av den reala monetära basen som förklarande variabel. Undersökningen fastställer ett starkt statistiskt samband mellan penningtermerna och BNP-gapet. Detta resultat förklaras av att samma avkastningar som avgör den aggregerade efterfrågan även är de alternativkostnadsvariabler som figurerar i penningefterfrågefunktionen..

I detta papper försvarar jag Ayn Rands metaetik mot invändningar presenterade av Charles J King. Vad är roten till alla värden? Ayn Rand menar att det är livet som är det yttersta värde och som därför gör alla andra värden möjliga och nödvändiga. Charles J. King delar inte denna uppfattning utan menar istället att det som gör värden möjliga är inte livet, utan förmågan att ha begär.

Back and forth is a study on wayshowing at events focusing on the Siesta festivalin Hässleholm. For several years the interest in festivals has increased, whichhas contribute to expansion among festivals. The Siesta festival in Hässleholm istoday one of the major festivals in Sweden, attracting 10 000 visitors each year.The festival?s strong expansion has contributed to disorientation in the festivalarea, because it has never been constant from year to year. A side effect of this isthat the orientation is a constant problem.Therefore this study aims to investigate how a clearer route guidance systems onthe Siesta Festival can be designed based on existing designprinciples onguidance and orientation and how the information can be accessable towheelchair users and those with some kind of colourblindness?Surveys among festival visitors and interviews with the festival organizers for thefestival showed which navigation strategies that are most used on festivals.

This study was conducted in the Master program at The Music Pedagogical Center (MPC) at The Royal College of Music in Stockholm. Korta musikresor (Short Music Journeys) is the Swedish term used for a receptive method of music therapy adapted from the tradition of The Bonny Method of Guided Imagery and Music (BMGIM) and the theory and practice of Expressive Arts Therapy. The KMR method uses carefully selected short pieces of music, lasting between 2 and 5 minutes, to work on various psychological problems and life- crises. The music session is conducted in a slightly altered state of consciousness with a clear focus being established beforehand in a verbal dialogue with the psychotherapist. There is also the possibility of using artwork to process and explore the imagery after the music listening.

Many of today?s societies are built on established financial structures that are controlled by states and central banks. These structures are built on a clear perception of economic systems as established but invisible institutionalised concepts that are operated by millions of organizations worldwide. An idea of counteracting against centralized economies by introducing a currency that no state or bank controlled was developed in the beginning of the 20th century. In 2008 the idea was realised by the introduction of Bitcoin, which is a digital currency and transaction system without any centralized emitter or controlling organ.

I Sverige genomförs varje år offentliga upphandlingar till ett värde av ca 500 miljarder kronor. Alla offentligt finansierade verksamheter måste följa lagen om offentlig upphandling och den formella upphandlingsprocess som lagen specificerar. Lagen är allmänt formulerad och anvisar en process där fokus ligger på förarbete och matematisk utvärdering.Cognitive Systems Engineering har vuxit fram utifrån insikten att effektiva processer kontinuerligt behöver använda såväl feedback och feedforward för att uppnå sina mål. Typiska tillämpningar är dynamiska, tätt kopplade processer där dessa behov är tydliga, men CSE som ramverk är generellt definierat och bör gälla även för en beslutsprocess på organisationsnivå. En CSE-analys har potential att förtydliga funktionella faktorer som tillåter upphandlare att genomföra effektiva och ändamålsenliga upphandlingar.I syftet att testa ovanstående hypotes genomfördes en fallstudie av Linköpings Universitets upphandling av företagshälsovård 2008.

Automatic milking systems (AMS) have been in commercial use since 1992 and have since 1998 increased a lot. The objective of this study has been to examine the development of udder health on farms converting to AMS. The study also included a comparison of how udder health developed depending on how farms handled cows with mastitis. This was because farms choose to either milk cows with mastitis in a separate barn or in the milking robot. Other studies on udder health on commercial farms have shown that somatic cell count increases both among individual cows and in the bulk milk when converting to an AMS. No differences between before and after converting to AMS in the proportion of cows treated for mastitis can be found in the literature.

The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.

The purpose of this report is to outline the development of a dynamic Microsoft Silverlight application, which will be able to present products and be administered in a simple manner. The project has been carried out at Incordia AB, a company that specializes in e-commerce, situated in Helsingborg, Sweden. Although the Silverlight application is customized for a particular site, forMicro AB (an ongoing project at Incordia), the template and the classes that are used to manage information, are developed so that they can be used in future projects for Incordia AB..

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.

Vi har undersökt hur Scandinavian Airlines Systems (SAS) årsredovisningar kanstuderas utifrån ord respektive siffror och vilket av de två som ger bäst informationför en extern intressent. Vidare har vi studerat hur väl redovisningen överrensstämmermed företagets situation. I studien har nyckeltal och analysmetoden Content analysisanvänts för att studera siffror i årsredovisningen, medans stycket ?VD har ordet? stårtill grund för analysen av text. Vårt syfte med uppsatsen är att bidra med kunskap omhur årsredovisningar kan användas av externa intressenter, det vill säga hurårsredovisningar kan belysa ett företags situation utifrån olika perspektiv.Studien bygger på både en kvalitativ och en kvantitativ metod på grund av uppsatsensuppdelning mellan att studera siffror samt tolka text.

The thesis examines how sex/gender and sexuality are represented through text and images within the Internet community Sylvia whose primary target group is girls. Through an examination of the aesthetics, the member rules and the choices that constitute the framework for the site, the study observes Sylvia as a cultural context. In relation to this setting, the ten most visited member profiles at the time for the study are more closely examined. These profiles are studied from a constructivist view of sex/gender and are analysed from the perspective of feminist and quee r theory as well as in the light of feministic debates concerning sexuality and erotica. The thesis shows how Internet as a forum and the non-heterosexual context Sylvia open up for a constructivist understanding of sex/gender and also leads to a questioning of "masculinity" and "femininity".

In Automatic Milking Systems (AMS), cows are kept in a free stall barn equipped with one or several milking units (MU). The cows? activities in the system are called cow traffic. There are three types of cow traffic systems: guided, partly-guided and free. Free systems have no gates, allowing the cows access to the feeding and resting areas at any time.
