This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.

Keywords: ID-method, internet, security, digitzing, bank Background: The digitizing of our society continues to grow and more parts of our lives is spent on the internet. The banks are one of the institutions that is at the forefront of this development since they established themselves on a early basis. The banks meeting points have since this establishment moved from the regular bank office out on the internet. A problem that has occurred during this transfer is the possibility to positive ID a customer in a virtual world. It is essential to offer the customer methods to identify themselves that are both safe and easy to use.

In recent time, agile methods have been devoted much attention, and the concept is widely used in the IT industry in particular. An increasing number of companies are interested in this way of working. The following report is the result of a study on the ability to create value for customers in business development through the use of agile methods. We ask what the advantages and limitations of agile methods are in the creation of customer value. Grounded Theory and an initial literature review was used to answer this question.

The aim of the study was to look at a particular work group of housing supporters, whomhave implemented two special working methods in their work. The methods have been implemented by two of the housing supporters that also have special education in the methodsSOC (Sense of Coherence) and solution focused brief therapy. The study is based on anethnographic observation and analysis of documents that are used in the implementation. To analyse the information that was given at the observation and in the document I´ve used a theory which illustrates the significance of developing professions so their knowledge become legitimate. I´ve also used a theory that illustrates the importance of implementation and how it´s done at its best.

This thesis takes on a broader perspective of the modern age phenomenon we call spam. One of the aims of this thesis is to present and to compare the variety of methods used in the day-to-day fight against spam, as far they have evolved today, but also to present and discuss some alternative methods for suggested future use. The properties of a common e-mail spam are analyzed to show how the components that make up the structure in an e-mail can be used to classify spam. Furthermore I explain the naïve Bayesian classification methods, the signature-based method, the commonly used rule-based method and the challenge and response method and discuss these. The widespread use of blacklists is also explained and a close new variant to blacklisting, Turntide is presented and discussed.

AbstractThe purpose of this essay was to study women?s and men?s place in the room, the public room or the private room, in the five best sold picture books written by Astrid Lindgren and the analysis was done with a feministic perspective. A lot of children read Astrid Lindgren?s picture books and therefore this might influence what?s female and masculine. The five best sold picture books written by Astrid Lindgren is: 1) Känner du Pippi Långstrump 2) Den där Emil 3)Visst kan Lotta cykla 4) Nils Karlsson-Pyssling flyttar in 5) Kajsa Kavat hjälper mormor.

This study presents a survey of the capital budgeting methods used in investment decisions by selected Swedish firms. The study has a qualitative approach where the main goal is to increase the understanding of why firms use ?incorrect? capital budgeting methods like the payback method despite the well known fact that it is one of the most faulty methods, according to literature in business finance (Brealey. Myers). The study has specially researched the impact of company?s size, investments size, ownership structure, branch traditions and political risks influence on firms capital budgeting..

The purpose of this study was to investigate the understanding of the diagnoses ADHD and DAMP within different professional categories in the educational system, how it is being addressed and how this affect their work with children diagnosed with ADHD or DAMP. We also wanted to shed some light on the debate between Kärfve and Gillberg, about whether the diagnoses of ADHD and DAMP are social constructed problems or biological and genetic disorders. More specifically, our study was of a qualitative nature and consisted of interviews with seven persons working in six different professions within the educational system. The respondents all worked in school environments but with varied roles and thus varied experience of children with ADHD/DAMP. The interviews and literature studies revealed the complexity of ADHD and DAMP and also the diversity of the debate regarding the diagnoses.

The purpose of this study is to investigate the reading methods that pedagogues, active in classes 1-3, use in the first stage of learning to read and how they consider their own choices of methods. In the theoretical background I sort out the basic differences between synthetic and analytic methods of acquiring the skills of reading. The analytic reading method means that the skills of reading starts with the complete text in order to later analyze the parts of the text. The synthetic method approach is based on a reading method where the parts are linked as a whole. The two methods are considered antipodes but can also be looked upon as complements in the current governing documents.

This essay talks about how teachers in schools are working with a particular focus on students with autistic syndrome. The aim is to investigate the methods used for these students, who develop their learning and achieve the goals of the school. The methods that were used in this study were two interviews in two different schools in central Sweden where teachers and professionals were interviewed. One part of the study was to compare both schools to see which methods they used and when they used them. My interest for autistic students started during my practice in a school.

This major project in Building Engineering has its focus on inquiring into what methods has been used in the planning process of the residential buildingLjusbojen 1. This project has been conducted in cooperation with Kadesjös Ingenjörsbyrå AB, an engineering contractor firm which also acts as the property developer. Initially several different general methods for planning residential buildings have been presented. After the methods from the process of building Ljusbojen 1 has been analyzed compared to the general methods presented in part 1. This shows what the determining factors are during the planning process; factors such as cost, quality, time management, know-how and environmental issues.

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.

Efficient numerical methods for option pricing is an active field of research. This project has the goal to examine possible ways to improve an established method of numerical pricing. The method is based on an adaptive finite difference method in price and uses the backwards differentiation formula of order 2, BDF2, in time. The project will focus on improvements to the time integration through implementation of discontinuous Galerkin methods, dG. Empirical convergence and accuracy results are obtained for equidistant dG-methods up to order 3 and performance is compared to BDF2.
