The aim of this thesis project is to produce an algorithm for finding a topologicalrepresentation of a polygon, called a straight skeleton, using floating pointarithmetic. Various straight skeleton algorithms are examined and discussed witha focus on time complexity and one is chosen for implementation. This implementationis then compared with the open source library CGAL with regards torunning time. The result is an algorithm which is based on an algorithm by Felkeland Obdrzalek and which, for polygons with more than five thousand vertices andthree significant digits representing points, runs around 25% faster than CGALsimplementation. Complications regarding the use of floating-point arithmetic arealso discussed..

Abstract One of the essential conditions of the co-operating within the EU is that homogeneous conditions of competition prevail within the entire common market. The competition policy in the EU should guarantee that the competition is not distorted in a way that would prevent or create difficulties for the free mobility of goods and services between the member countries. The policy of competition should also guarantee that no new protectionistic obstacles will be formed, regardless of if it is being done by actions taken by member countries or as a result of actions taken by companies in order to set limits to the competition. Companies putting to an abuse their dominant position on the common market, or on a substantial part of it, is irreconcilable with the idea of the common market in case it could interfere with the trading between member countries, and is thus prohibited. The purpose of this dissertation is to describe the collective dominance from the view of the commission's interpretation of the practice of article 82 in the EG - treaty.

I mitt examensarbete har jag valt att försöka undersöka i vilken utsträckning det i en hemmastudio är möjligt att återskapa ett sound från en professionell inspelningsstudio. Denna fråga är intressant för mig då jag fastnade för hur en produktion lät i ljudbilden. Dels instrumentuppsättningen och deras rytmisering men främst soundet på helheten i mixen. Det kändes luftigt, stort och brett i lyssningsspektrat trots att det inte var så mycket instrument. Jag har alltid velat utveckla min förmåga att skapa och producera musik men har inte tillgång till så mycket kvalitativ utrustning.

The purpose of this study was to develop recommendations for using more efficient lighting and better graphic design to create a more uniform structure in the exhibition hall ?Road to the past? in Jönköping County Museum by answering the following questions at issue:1) How are the objects in the exhibition hall ?Road to the past? exposed today?2) How can you use lighting and graphic design to create structure in the exhibition and strengthen the expression in the exhibition?Our work is based on observations and open group interviews. We observed the exhibition hall ?Road to the past? during day and evening. In the same hall, we observed a guided tour that we followed up with open group interviews.

The legal courts in Sweden have developed a case law wherein the application criteria for being eligible to acquire unemployment insurance have become strict and rigid. This is in particular true when it comes to professional athletes who cannot make a living on their athlete wage. It is the 9th to 11th section of the Swedish Law (1998:238) on Unemployment Insurance that set the determinants for who of the unemployed is to be considered as being of disposal to the labour market. The strict and extensive interpretation of the relevant sections has been based upon a literal reading of the relevant preparatory works to the law in question. A substantial amount of relevant cases as well as preparatory works have been examined to investigate whether there is a need for revising this case law.

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.

The purpose of our report was to analyze the effects of youth drug abuse on the families concerned. Youth drug abuse made us wonder about the effects on the family as a whole, of those involved with drug abuse. To answer this question, we decided to employ an empiric study in the form of interviews with four teenagers, five parents and four drug counselors. Because our intent was to understand rather than try to measure the problems involved, we decided on a qualitative method. Our method built upon semi-structured interviews using open questions, where the interviewees were free to express their own thoughts and opinions.

In this Masters thesis we investigate query expansion using an electronic thesaurus. We formed 30 topics from the library and information science field. For each topic three searches were made in the bibliographic database LISA Library and Information Science Abstracts via CSA Cambridge Scientific Abstracts. LISA has an electronic thesaurus attached. We used this thesaurus to form baseline queries, baseline queries expanded with synonyms, and baseline queries expanded with both synonyms and related terms.

The fundamental prohibitions against anti-competitive agreements and abuse of a dominant position are set out in the EC Treaty, articles 81 and 82 respective CL 6 and 19 §. EU: s objectives can be said to promote economic and social development within the community. These objectives will be achieved, among other things, through the establishment of a common internal market. In order to achieve a common market, where companies from different nations compete on equal conditions, it is not enough to prevent the member states from distortion of competition in the market. The free competition and thereby the advantages the common market is assumed to create, can also be limited through measures taken by companies.

Uppsatsen tar upp problemen med det ojämna uttaget av föräldraledighet mellan könen. Männen tog år 2004 endast ut 18,7 procent av föräldrapenningdagarna, kvinnorna tog ut 81,3 procent. Detta medför en stor skillnad mellan kvinnor och män, i förutsättningarna på arbetsmarknaden. Föräldralagstiftningen är till för att underlätta och stötta föräldrar vid barnafödande, och möjlighet att förena föräldraskap och arbete. Familjen får lagstadgad ledighet och ekonomiskt stöd under barnets första tid, och den är i sin utformning könsneutral.

Computational thinking was brought to the forefront in 2006 by Jeannette Wing. Computational thinking is a problem solving method that uses computer science techniques.The thesis is analyzing computational thinking and how it could be applied to graph theory. Characteristics and main fields from computational thinking is being analysed. This analysis is applied to graph theory to see the potential in developing a proposal for how an exercise can look for an introductory course in discrete data types. Only basic knowledge of graphs is required to perform the exercise.

Introduction: Parents have been shown to be of great importance in preventing cannabis use among adolescents. Parenting practices such as control, open communication and good relations within the family have shown to be protective factors, whereas lack of communication and weak social and emotional support have been associated with an increased risk for cannabis use among adolescents. Aim: The aim of the study has been to explore parents? perceptions about their own importance in preventing cannabis use among adolescents. Method: A qualitative method consisting of focus group interviews has been used to fulfill the aim.

The aim of this Master?s thesis is to explore the meaning of literature forliterate immigrants in regards to identity and integration. The study is based onqualitative interviews with eight Swedes of various backgrounds, but with thecommon experience of an immigration process. In addition to being migrants, therespondents are also public library users who have an interest in literature and whoread literature during their leisure time. To analyze the empirical material ananalytical framework, consisting of a number of analytical concepts from Libraryand Information Science, Literature Science, and Sociology, has been used.

The fertility of dairy cows is of great importance in order to maintain high production. The decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.
