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.

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.

Doktriner utgör väpnade styrkors viktigaste beskrivning avseende hur man avser använda militära medel för att uppnå politiska mål. För att tjäna sitt syfte bör doktriner utvecklas med rationella utgångspunkter som omvärldens utveckling och senaste forskning. Dock menar många att andra faktorer sprungna ur kulturella traditioner och organisationers särintressen påverkar tillkomsten av doktriner.Civil-militärt samarbete har i moderna konflikter blivit allt mer betydelsefullt. Strategier för fredsfrämjande insatser i dagens komplexa konflikter bygger i allt högre grad på integrerade insatser mellan flera olika funktioner och aktörer. Civil-militärt samarbete har dock traditionellt haft en underordnad, stödjande roll i militära organisationer.I denna uppsats undersöks forskningens roll i doktrinutveckling.

The purpose of this master thesis is to investigate how some children's librarians view their working situation. There is one main question and three subquestions at issue: How is the working situation of the children's librarians today described by agents on the library field? - Are children's librarians ascribed any value and has this changed during the last three decades'? - What is the apprehension of children's librarians and what qualities should they possess? - What is considered to be most important about work of children's librarians'? The thesis is based on qualitative interviews with children's librarians, library managers and library consultants. The interviews are analysed by the help of Pierre Bourdieu theoretical concepts; capital, habitus, field, doxa and distinction. Today, children's librarians are ascribed capital by their librarian colleagues because of their specialist qualifications.

Due to the obvious fact that one can never be hundred percent sure of what's hiddenunder the ground surface, construction work is naturally hard to project.However, many of the work methods are executed in the same way on variousprojects. The department of construction work at JM AB region öst describes a lackof follow-ups and feedback between the calculators and production managers.In this thesis we have studied the communication between these groups and alsohow they share experiences and knowledge. In order to get the full pictureof the day-to-day operations we used three methods to gather information. Studyingliterature gave basic knowledge of theories about feedback, and thenecessity of working with giving feedback. In order to understand the process ofconstruction work we made several interviews, both structured and nstructured.

This Bachelor's thesis examines and describes the ideas and ideological traits surrounding the public library within the governmental cultural policy. The Bachelor's thesis demonstrates how the public library ? even though its relevance in the modern society has shifted over time ? has maintained a connection to the governmental cultural policy and has therefore been shaped by the ideological changes in the political sphere as a whole. The main issues are: Which ideas concerning the public library's functions are expressed in the governmental cultural policy? Which ideological tendencies can be identified in the national cultural policy? Which ideas concerning the public library can be extracted through the found ideological tendencies? The method used in order to study the governmental bill is an ideology analysis based on a framework created by Dorte Skot-Hansen.

The reason why this study has been made is the fact that a substantial part of students in the upper secondary school changes their field of study, during or after their first year. The aim of this study is to find out the reasons behind such changes as well as finding out the affecting factors. The study has been made in two steps, first quantitatively by a poll study and the second step is qualitative by interviews. This research has been made in both private schools and municipal schools, with the ambition to search for differences between these two separate school forms. The study shows that no general differences can be found in a comparison between them.

AbstractThe aim of our study was that from a Preschool Manager?s perspective to describe, analyze and understand the function of special education and the Special Education Teacher?s profession within preschools. We conducted twelve interviews with Preschool Managers in two northern Swedish municipalities. From a theoretical base, we used both the relational and categorical perspectives. All answers from these interviews have been analyzed from these perspectives.

The aim of this study is to investigate into the use of discussions in the classroom to help the pupils develop a deeper understanding of mathematical concepts and operations. The empirical data contain interviews with two teachers and observations from their lessons. The purpose of the interviews was to find out what importance the teachers ascribed to the ability of their pupils to talk about mathematics, and how they organised their classes to encourage mathematical discussions. With the observations, I was able to see the interaction in the classroom and hear discussions between the teacher and the pupils, as well as between the pupils themselves.The interviewed teachers proved to share my own belief in the results of researchers like Malmer (1999) and Löwing (2006) about the importance of verbal discussion, argumentation and reflection during mathematics classes. But convictions derived from the research of others are one thing, the practical application of the wisdom in the classroom another.

This Bachelor Thesis in the area of Computer Science and Work Science describes the process of design and development of an IT-tool between the municipality of Ron-neby and TietoEnator a development and consultancy firm, the Gothenburg office. The thesis focuses mainly on the cooperation between the consultant designer and the local municipal. Through cooperation, the organisation is incorporated into the tool and the tool is incorporated into the organisation. Concepts that are central in this thesis are design, cooperation and tailoring. A question raised is, if distance work and extensive cooperation might be a good way of working in the process of design and development, when the organisation is being incorporated into the tool.

SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.

This is a study on the outcome of the Swedish Forest Agency´s mission to provide individual advice to private land owners about precommercial thinning. The study was conducted in Sala municipality and included forest owners that had received private individual advice from a Swedish Forest Agency consultant as well as forest owners that had not received individual advice. One of the central issues was to make comparisons between these two groups. The survey was carried out by telephone interviews combined with a smaller field study. The questions were designed to provide information about to what degree the forest owners had been affected by the advice and if there had been a change in the way in which precommercial thinning was performed. In terms of the amount of precommercial thinning that had been carried out, no statistically significant differences were found between the two groups.

The subject of this thesis is to ascertain the task of the public library in Swedish society today according to the employer, that is the State and the municipalities, and according to the public library itself. The thesis also tries to establish as to what extent these different actors share the same view of the task. To this purpose I have studied the library law, the target reports of municipal authorities and public libraries, and made interviews with public library representatives during the autumn of 2001. The particular consideration of this paper is whether the task is being described in active, culture making terms or in passive, service functionary terms. Initially, I describe the task according to the library law.

AbstractFor an audit organization, it is important to work toward maintaininga high error climate to handle errors in an efficient and propermanner. This means that it is important for accountants to worktowards high quality of work, reduce and manage errors that mayoccur in their daily work. Therefore, auditors must know how tohandle errors in order to improve efficiency, which can be affected byhow leadership is exercised in the workplace. The error climatemeans being able to act in a manner which will ensure a good jobtowards customers but also within the internal operations.The ethical leadership may thus have an impact on how auditorshandle the error environment both internally and externally. It is veryimportant for customers to have confidence in the business but also tomaintain the order and the general rules of society for accountingfirms.My study aims to show the thinkable relationship between ethicalleadership and the error climate.

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
