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..

Today, a large proportion of wood supplied for the Swedish forest industry is bought from private forest owners while forest companies at the same time provide the forest owners with services such as logging services and transportation. Today, forest companies work extensively with keeping the time used for transport and logging short. But what does the private forest owners think about the time required for the timber deal, also called lead time, and the different parts of the timber deal. In this thesis, the forest owners? perception of the different lead times in their contracts with Stora Enso and their communication with the purchasers is examined.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands. The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.

This study aimed to investigate written and oral narrative in adults. The participants consisted of 30 subjects aged 32-79 years. They produced one picture elicited and one free narrative, both written and orally. The written narratives were recorded in a keystroke logging program and the oral narratives were transcribed orthographically. Data from all the narratives were analyzed according to: number of words, words/minute, active writing time, total process time, number of characters and number of characters in the final text.

Introduction: More and more children and young people get the diagnosis celiac disease established. Celiac is a life-long disease, which means that the child during the rest of its life has to be on a strictly gluten-free diet. There are few studies so far, which have examined how children having a life-long disease with food treatment and increasing prevalence really experience their health related quality of life (HRQoL).Purpose: The purpose of the study was to examine how children (8 ? 18 years old) suffering from celiac valued their HRQoL and to illustrate as well whether the age of the child and its extent of disease when it was taken ill affected the child?s evaluation of HRQoL later in life. The purpose was also to compare whether the children?s parents valued the HRQoL of their children to the same extent as the children did.Method: 160 children, 54 boys and 102 girls were included in the study.

This master thesis examines online reading groups with swedish participants. The aim is, by way of introduction, to investigate what kind of online reading groups that exist and how they work. The overall question of the thesis is: how do a conversation about books on the Internet look like? The theory used is Grounded Theory and this is a methodology which has influenced the hole structure of the study. Grounded Theory apply that issues and hypothesis must be created from the collected material, and the author collected for this reason material in the form of survey answers, email-conversations, blogmaterial and articles to draw up exact issues based on this material.The material was sorted into four different categories; social reading, reading fellowship, virtual freedom and anonymity and the issues were formulated according to this categories.

The visual complexity in real-time applications, like computer games, is increasing with customer demands on vissual apperance. This trend is supported by even better graphics cards from the hardvare industry. This must be taken into consideration when the architecture of a new graphics engine is to be designed. The engines renderer is responsible of generating a picture of scene data. The renderer must cope with increasingly more complex scenes, and must be able to render them depending on available hardvare capasity.

The aim of this master-thesis is to investigate the emergence of bureaucratic drift in connection with implementation of EU-legislation in Sweden. To narrow it down I have chosen to look at the Swedish implementation of the Working Time Directive, directive 93/104/EG. To be able to fulfil the purpose of this master-thesis I have used two research questions; [1] How did Sweden implement the Working Time Directive into Swedish law? and [2] Why did Sweden omit to correct implement the Working Time Directive? To be able to understand and explain the situation I have used the principal-agent perspective as a theoretical framework. An analysis of motives has been used as analytical method.The results from the analysis show that Sweden, in order to keep the contractual model used on the labour market, which is a part of the well known Swedish model, shirked while implementing the directive and implemented as to be able to fulfil its own agenda.

In this essay I employ memory theories to examine Absalom, Absalom! by William Faulkner. How are the memories depicted and how do they function in the novel? What are the characters ?allowed? to remember? Scholars that have written about William Faulkners usage of memories and narrative time in his novels, often claim that they together represent and create a sense of determinism and/or fatalism. Even though I agreed with that opinion, regarding time and memory in a lot of Faulkners novels, I wondered if these features in the text might not represent/mean something more, beyond that. One scholar have expressed the view that William Faulkners characters resemble blind marionettes of Destiny. I instead claim that the characters themselves, via their individual memories and temporal relations, create an internal determinism, connected with cultural memory, norms and traditions. I try to examine both the individual memories, as depicted in the novel, and the novel in its entirety, using different memory theories and narratology. .

This report represents a comparison between two different tools used to create an online store that was developed by two students at the Technical University in Jönköping. The web shop will be of great benefit to both customers and administrator in a food firm known as Mattias' Livs. The company wanted an online store that facilitates the sale section and gives a full control of their stocks. The aim of this thesis is to create an online store that offers customers the ability to shop online and help the staff to operate the company in a simpler and more efficient way, which reduces the need for human resources and thus leads to less costs for the company. The aim also includes a comparison between the two different tools used to create the online store.

Boliden Mineral Ab's mine in Garpenberg, Dalarna is going through a massiveexpansion. The annual ore production is being increased from 1,4 million tons to 2,5million tons in less than two years period of time. Along this expansion thedepartment of mining techniques is administrating a project of optimizing the shortterm planning for the mining production. Garpenberg have since mid 90s storedinformation from all mining processes in a database.The information consists of time data from all the different activities required in themining process, for example charging, blasting, loading etc. The database also containstime data of delays that are affecting the production.
