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 target group of the study was employees (eleven), their managers (seven) as well as co-ordinators (two) of a maintenance department at a nuclear power plant. The training program lasted from December 2009 to May 2010. The study was in progress as of September 2009 when a decision was made at the maintenance department?s training board to carry out the evaluation.

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.

AbstractIn this essay, policy change and learning is studied in the case of the Social Democratic Party and their policy concerning independent schools. Their policy differs clearly from the right-wing parties. Between 1991 and 1994, the right-wing government made substantial reforms concerning independent schools. The question posed in this essay is whether the policy of the Social Democratic Party has changed as a result of these actions, and if they have approached their right-wing counterparts.Using the Advocacy Coalition Framework, defining a policy as a result of the values the actor holds, the question is studied by applying the theory's assumptions of policy-learning across coalitions. The argumentation of the Social Democratic Party, as it is expressed in official text documents before and after the right-wing government, is analysed.

This is a qualitative study aiming to find out how and why teachers work with art, music and movement in the English subject in the early years. In this study we have conducted a background study of previous research and as a starting point and as a point for reference we have relied on education policy documents like The Common European Framework of Reference for Languages and the Swedish curriculum for the English school subject. Our research has consisted of interviews with six teachers and ten observation occasions in a total of three different primary schools. Our result show that there seems to be a consensus in both theory and praxis when it comes to integrating art, music and movement in learning and teaching of English in the early school years. The use of methods including art, music and movement in early language learning seems to promote the language development for all students but especially for young learners that require extra support for their language development.

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.

The purpose of this study is from a teacher?s perspective to examine how schoolteachers experience the possibilities of learning from each other within their work team and to shed some light on how teachers believe that cooperation affects their ability to learn and improve on a daily basis. My research questions are: What is the general discussion among the teachers concerning daily capacity building from enhanced teamwork? How important is well-functioning cooperation between co-workers for learning and daily capacity building? What are the prerequisites for a well-functioning learning situation within the work team?The study is based on five qualitative interviews with teachers within the same school but from different teaching backgrounds based on what grade they teach, what subjects they teach, and they belong to different work teams within the school. The interviews are semi-structured.The results have been analysed from a perspective based on the theories of organisational pedagogy and learning organisations.The results implies that the work teams does not function as a forum for exchanging experiences and learning from each other.

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.

The purpose of my empirical study is to see if and how teachers meet the students needs of physical activities in the daily work in the classroom. I also want to explore how different teachers see the connection between the concepts: physical activity and learning. To fulfill the purpose, I have chosen to ask four questions that I will work on in my study.How much and what type of physical activities do the students do in a typical day at school?What happens with the students when they have had a moment of physical activities in the classroom?Do the teachers see any connection between the physical activity and the pupils' ability to concentrate?How do teachers look upon the relationship between physical activity and learning?To get answers to my questions, I have observed and interviewed five teachers. I have compiled and analyzed the results.

Syftet med studien är att bidra med sådan kunskap att det nybildade e-learningsföretaget kan skapa ett så attraktivt utbildningspaket som möjligt.

Dessutom vill vi se om det är troligt att kunden kan anamma utbildningspaketet inom en tidsperiod av ett år..

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.

Vi har i en tidigare kurs genomfört en uppgift innehållande bråk, då vi upptäckte att elever hade svårt att lära sig framförallt sammansatta bråk. Vi blev intresserade av att ta reda på hur man skapar förutsättningar för att eleverna ska lära sig bråk, vilket är denna studies syfte. Studien syftar även till att upptäcka vilka aspekter som är kritiska för att lära sig bråk samt ta reda på hur dessa kan varieras i undervisningen vid elevernas lärande av bråk.I studien används en learning study som kan ses som en typ av aktionsforskning där lärare forskar i sitt eget klassrum. Inom learning study används variationsteorin som är en guidande princip för att förstå och skapa förutsättningar för lärande. Lektionerna som genomfördes av oss, blivande lärare, vid tre olika tillfällen videofilmades.

Swedish pre-school teachers are in the middle of a debate regarding a form of general school competence that today is criticized by mass media. The training and skill development that is used today is an important tool in the development of the organization as well as the people that work in them. This study aims to explain how this training actually is performed and the opinions of the pre-school teachers that actually finish the training. Previous research in this area has primarily been focused at the types of methods that exists from an executive standpoint. This study, instead, aims to shift that focus to the individual worker.

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.

The aim of this qualitative respondent investigation is to delve into the various views that teachers have concerning the ?One-to-One project?, as well as the use of computers as an aid in teaching. One-to-One means that teachers and students will be equipped with a laptop they can use at home and at school.This essay looks at how several factors have changed as a result of this. These factors are threefold: the role of the teacher, the teaching experience, and the student´s learning process. In order to answer the mentioned questions, four interviews have been conducted at two different high schools in southern Norrland.
