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.

ABSTRACTIn this study I have analyzed, throughout a gender perspective, two textbooks Den levandelitteraturen and Upplev litteraturen which are purposed to be used as teaching materials inSwedish schools in the subject of Swedish when teaching the history of literature. The intentof this study was to provide a gender analysis of two textbooks and the focus was on thepresentations of female and male writers, because they have not been studied earlier. In thisstudy, a qualitative text analytic method was used to achieve the best results as possible.Theories used in this study were Yvonne Hirdman?s and Raewyn Connell?s theories. Hirdmanclaims that there are differences between men and women at different levels in the societywhile Connell believes that this is a myth because, according to her, men and women arepsychologically alike.

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.

This essay examines teaching in source criticism in upper secondary school history education. Two questions are to be answered: 1. What are the conditions like for teaching source criticism? 2. What opportunities for further development in teaching source criticism are there? In order to set a standard for what knowledge and skills in source criticism the students need, I design a four step model for good source criticism based on the historical science.

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.

The aim of this study was to examine how the interviewed primary teachers in two schools situated in the Stockholm area understand themselves as teachers in relation to their image of the good teacher. The research questions were: How do the informants discuss their image of the good teacher? How do the informants describe their own role as a teacher?A qualitative method, by interviews made with four primary teachers, was used to collect data for the examination. The results from the interviews were analyzed and discussed from the theories and earlier research concerning the role of the teacher and what they describe as the good teacher. The theoretical connection of this study was based on the theories of Vygotsky, Piaget, Bruner, Dewey, Dreikurs, Kounin and Glasser concerning the relationship between the role of the teacher and learning.

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.

This is qualitative study of, four teacher´s views on the use of iPad in teaching and learning. In addition, I will examine the disadvantages and advantages of iPad use as a teaching tool in preschools.My questions are:What is the practical use of tablets in preschools today?Are preschool teachers using the tablet as a teaching tool? If so, how?Is the use of tablets in preschools contributing to children´s social interaction, as well as between children and teachers` social interaction?The purpose of this study was to find out how the four teachers uses the iPad as a teaching tool in the interaction between children in preschool. I have chosen to use Vygotsky?s and John Dewey´s theories.

The purpose of this discourse-analytical study is to investigate teachers? beliefs about writ-ing and writing instruction and how their beliefs and writing instruction can be understood in relation to the Lgr11 syllabus in Swedish. The study included five teachers who teach in grade 6 of primary school, where I applied Roz Ivani??s theories of written discourses, based partly on interviews with teachers and classroom observations of teaching, partly on the Swedish curriculum for grades 4?6. The result shows that teachers move within creativi-ty, process, genre and social practice discourse, while the skills of discourse and the socio-political discourse lack matching.

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..

This study focuses on teachers? and pupils? experiences of their use of one-to-one computers in civics education in Swedish upper secondary school. The experiences of teachers and pupils will also be put in relation to the content of the formal curriculum. The aim of this study is to investigate whether the access of one-to-one computers has changed teaching and learning within civics. The theoretical approaches used are both Tomas Kroksmark?s theory about traditional versus innovative learning and Ruben Puentedura?s SAMR-model.

The purpose of this thesis is to carry out a qualitative study of the perceptions of language teachers as to their role in the teaching of values and morals to pupils. Five language teachers have been interviewed about their perceptions of how values are taught and their role therein. The interviews serve to investigate the reality of teaching values to pupils in a Swedish secondary school and the work involved in this on-going process, this being with a view to having a better understanding of just how important a role the teaching of values plays in the daily working life of a teacher. Terms such as fundamental values and morals can be difficult to define as they are highly personal and can differ from person to person depending on one?s background, experiences and family circumstances, for example.

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.
