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..

This paper tests the information signalling hypothesis on a sample of firms making open market stock repurchases. Using an earnings-based valuation model, we find that a majority of repurchasing firms are undervalued relative to their economic value. This result is consistent with previous academic studies, which claim that undervaluation is the prevalent factor explaining the observed abnormal return following the announcement of a repurchase program. We do not, however, find any evidence that the repurchase is consciously made by management to provide the market with new information. .

This Paper examine how a municipality hire employees and in what way they use relevantlegislation in the recruitment process. The purpose of this paper is to clarify one specific municipality and their recruitment process, where the selection of the candidates is in focus of the process.The premiss is that municipalities can hire whoever they want, although some legislation needs to be considered. The principle of objectivity, the precedence and prohibition against discrimination are some restrictions municipalities must be aware of and not contravene.Further on candidates have an opportunity to require probation of the legality if they experience that mistakes have been made with the recuritment. However, only members of the municipality can emphasise this request.The municipalities job advertisements conformation and demands will be clarified in the paper. Job advertisements has a validity regarding disputes refering to discrimination because only the advertisement can justify employers procedure and choise.

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.

A new shipyard on the island of Beckholmen consisting of a new ship hall and complementary workshops. The program is extended with rentable industrial space for other smaller companies to take advantage of synergies with the yard and to create an active maritime cluster around Beckholmen. By building a marina and a port at the northern shoreline of the island the shipyard can expand their potential customers to non-commercial and larger recreational boats that are becoming increasingly common in Skärgården. The port is also supplemented with a combined naval fuel station, harbor office and a small café. The boat traffic in the region gets a additional stop at the end of the port and act as an additional gateway to Djurgården. Several small retail spaces with direct access to the water is created along the promenade between the port and Djurgården. The shipyard gets a modern and efficient industry building, while the island is made available to the public again, and Beckholmen will hopefully take an equal place in the city's consciousness as it does visually in the inlet to Stockholm..

Individual adaption to the student´s needs is a recurring main theme in the new Swedish curriculum (Lgr11). The purpose of this qualitative study is to examine how teachers work with individual adjustment for students with reading and writing difficulties. The study was based on five questions;In what way do teachers organize their teaching in the classroom individually for students with reading and writing difficulties?What methods do they use for student´s with reading and writing difficulties?What difficulties do they encounter in their teaching?How do the teachers reason to curriculum goals regarding individual adaptions?How do they think about their own knowledge regarding reading- and writing difficulties and dyslexia?The method for my study was qualitative interviews. Five teachers were interviewed in semi-structured interviews.

Studiens syfte var att undersöka och analysera pedagogers erfarenheter av en skriftligutformad plan för att motverka diskriminering och kränkande behandling i förskolan. Det ären kvalitativ studie som bygger på intervjuer med pedagoger på förskolor.Frågeställningarna som låg till grund för studien var: Hur upplever pedagogerna processenkring utformandet av den skriftligt utformade planen för att motverka diskriminering ochkränkande handling? Hur beskriver pedagogerna den skriftligt utformade planens användningi arbetet att motverka diskriminering och kränkande handling? Vilka utvecklingsmöjligheterser pedagogerna kring den skriftligt utformade planen som verktyg i arbetet att motverkadiskriminering och kränkande handling?Resultatet i studien visar bland annat att pedagogerna upplever processen kring utformandetav planen som svår då det till exempel var svårt att få tag i information. Användningen avplanen beskriver pedagogerna som en punkt på dagordningen, de tycker att den användssamtidigt som den upplevs mer som en pappersprodukt än som ett innehållsförankratdokument. När det gäller utvecklingsmöjligheter kring planen ger pedagogerna uttryck för attde själva behöver mer kunskap i ämnet och planen behöver på olika sätt implementeras meri verksamheten..

This thesis has been done in order to ease the process of drawing schematics ofelectrical wiring. The need arose after demand from the government due to a seriesof incidents that took place during the revision of the nuclear power plant in year2009.The task of the project has been to create a computer program that can generate agraphical representation of the electrical components relations. The basis for theprogram has been an example of how the client wants the graphical representation tolook. During the course of the project weekly meetings have occured in which theclient has reviewed the work.The result of the project is a program written in Visual Basic Applications that can berun in Microsoft Excel.

The so called ?ByggaF-method? is a relatively new Swedish method to stop moisture from being built into a building. The method should prevent damages on buildings as a result of mould growth and moisture. The purpose of the method is to include moisture control in the entire constructionprocess, from the projecting phase and all the way to the management phase. Up until now, there is no proof if the method is profitable or not and no studies have been made on the topic.

Unlike previous research, this thesis considers the possibility of regarding the morning prayers in Swedish schools as preaching, rather than teaching. 28 morning prayers, delivered in the church of S:t Johannes in the city of Malmö during 1939-1954 by the religious teacher Astri Heimer (1889-1986), constitutes the material for analysis. The purpose of this thesis is to examine if Heimer's morning prayers may be regarded as preaching, and to discuss the significance of this, in particular considering her role as leader of morning prayers.The examination is conducted in three steps. The first step investigates how morning prayers in general ought to be understood - as teaching or preaching? This is done by describing and comparing the literary genres of religious teaching and preaching, looking into the rules and principles which define the field of application.

The purpose of this study is to portray conflict managing associated with children in a small class and what problems they may face each day at school. What types of conflicts and what consequences do teachers practice? This study is based on these following questions:Is there any difference for solving/measure for students with psychosocial problems or ADHD in a conflict or does teachers still works with the same methods?What types of conflict solving does schools use?What is important to consider with students in a small class who has psychosocial problems and ADHD to prevent conflicts?Summary: To answer my questions in this study, I´ve used qualitative methods, interviews and observations. I have used my cellphone for recording the interviews so that all content from the informers are accurate. My theoretical points concerns on having strict rules both inside and outside the classroom.

The purpose of this study is to examine what creates motivation in the workplace of a small company with a high employee satisfaction index. The case study consists of qualitative interviews that help explain what the most important motivational factors are for the experienced IT consultants in a company that was founded by a circle of friends. The study concludes that the unique and equal pay model implicates an economic risk to the individual consultant but results in liberties, synergies and benefits. These appeal more than either self-employment or work at a larger IT consultancy that several consultants have backgrounds in. An expansion is ongoing since two years back, which threatened the culture but implicated opportunities for the individual consultants.
