Algoritmer för objektdetektering i SAR och IR-bilder
The first part of the thesis consists of a brief introduction to the general principles of target detection and the sensor-systems used. In the following part there is a theoretical description of the algorithms this thesis focuses on. The detection algorithms described in this paper are called Cell Average, Ordered Statistics, 2parameter and Gammadetector. Two different discriminators called Extended Fractal Features and Quadratic Gamma Discriminator are also described. The algorithms are tested on three different types of data, simulated SAR-pictures, authentic SAR-targets and IR-pictures.
Vulkanisk svaveldimma : Risken att det drabbar Sverige
In the year 1783 a fissure eruption from Laki in the southern part of Iceland produced a large amount of volcanic gases during a period of eight months. The volcanic gases and aerosols spread across the northern hem sphere due to ideal weather conditions and had a substantial impact on the environment, human health and also climate effects. This, so called dry fog, caused severe health problems, which led to death casualties, killing animals, crops and other vegetation. The consequence was a widespread famine which was aggravated by a hard and long winter in 1783/84. Analysis shows that the Icelandic volcanoes are the primary risk to produce dry fog that can affect Sweden.
Den representativa demokratin och kompetenskraven : En studie av kompetensnivå och kompetenskrav på kommunpolitiker
The local politicians in Sweden are responsible for a great deal of the welfare system why one would assume that there are a lot of demands put on them - demands for certain skills or a certain level of competence. I have in this study tried to find out how the demands on the local representatives concerning the demands for competence and the actual level of competence among the politicians are affecting the local politics. This was done through investigating how the local politicians are perceiving their level of competence and the demands put on them, but also how the employees are perceiving the demands and the level of competence put on the politicians. The study was made in the municipality of Gislaved in Southern Sweden. I was using both quantitative method (an opinion poll among the politicians and employees in the municipality) and qualitative method (interviews with three politicians and three employees and literature studies).In order to investigate the demands for competence I split the concept into ?soft? competence (socially and emotionally based skills), and ?hard? competence (skills based on knowledge, education and experience).
Eslövs stadspark : stadsparken som inte var en stadspark men som vill bli
Eslöv received its city privileges in the year 1911 and to celebrate the city?s 100th jubilee it has been decided, among many other things, to reinvigorate the City park. This master thesis presents a new proposal for the design of the City park. As a basis for the new proposal a study of the public park is made in a social and structural context as well as a study of the history of the Eslöv City park. The history of the Eslöv City park is somewhat unclear, especially if there has ever been a one design for the whole park?
To create a picture of the public park in general, a study of literature has been made and to describe the history of the City park I Have researched the city archive in Eslöv.
Pausgympa och koncentration : Elevers upplevelser av pausgympa i klassrummet
The purpose with this study was to see the relation between gymnastic pause and concentration to find out the students in a first grade experiences and thoughts about gymnastic pauses in the classroom. I have made a qualitative study to fulfill my purpose, I have observed students before and after the gymnastic pauses, carried through gymnastic pauses with the pupils and interviewed pupils in group.Previous research shows that the good working atmosphere and concentration has improved when pupils have had gymnastic pauses but it is difficult to say how it looks in the long term when the research doesn?t show that.In my study, it appears that the gymnastic pauses make it calmer in the classroom. Some of the pupils believe that they have had a better ability to concentrate after the gymnastic pauses while some pupils believe that they have not had a better ability to concentrate. Some pupils say it's good to get a break to carry on with the schoolwork during the entire lesson.
Kan professionell skepticism användas för att förutse revisorers beteende?
Auditors have a big role in society. The question of auditor independence has been debated frequently after the financial crisis. Long auditor tenure with clients has both advantages and disadvantages so the question is hard to solve.One of the traits that are encouraged with auditors is professional skepticism. An important part of professional skepticism is the personal skepticism of the auditor. The purpose of this dissertation is to investigate if a high professional skepticism can increase auditor independence by increasing profession identification and decreasing client identification.
Ledarskapsutbildning inom byggingenjörsprogrammet vid Högskolan i Halmstad
The purpose with this essay is to examine different roles of leadership in the working environment by interviewing ex-students that have taken their degree from Halmstad Högskola and its construction program. How do these ex-students handle to be in a position of power in their everday life and how do they handle decision making? Do they find that the education they have recieved in any way has helped them in regard for leadership or do they rather conclude that further education in the area of leadership would be beneficial? These are the questions that I set out to shed some light over in this essay. This study consists of one part theory and one empirical part. The empirical part was accomplished by interviewing ex-students from Halmstad Högskola and this part was later compiled with relevant theories on the subject which were obtained from books , internet and various databases.The results from the interviews show that the general point of view is that the subjects containing leadership in their education hasn't really helped them.
En vältränad och hälsosam kropp - eller bara en täckmantel för vad det egentligen handlar om? : En innehållsanalys av träningstidningarna Body och Fitness
The aim with this Essay is to examine the two most read magazines in Sweden covering the areas of exercising, fitness, bodybuilding, diets and ?wellness? ?Fitness and Body. Fitness?s target group is predominantly woman, while Body is almost exclusively read by men. The analysis is first done quantitatively, by systematically categorising the contents of the magazines.
Deltidsarbetandes företrädesrätt till högre sysselsättningsgrad
During the 20th century Sweden faced an increased proportion of workers registered as part-time unemployed, especially in the care sector. However, due to many valuable efforts, aimed at solving the problem of part time unemployment and political decisions, the number of people who are part-time unemployed has declined since the late 20th century. We have investigated part-time workers preferential right to extending their working hours. According to Section 25 a of the Employment Protection Act, part-time employees who have submitted an interest in increasing their working hours has a preferential right to increased working hours, with the assumptions that full-time employment with the employer will meet a labor need that the employee has sufficient qualifications for.Qualitative interviews have given us information about how Karlstad Community and a private care company deal with part-time unemployment and their workers preferential right to extending their working hours. We have found that people who work for Karlstad Community have an opportunity to choose their number of workings hours, thanks to a political decision made in Karlstad Community, aimed at solving the part time unemployment in the care sector.

The most frequent cause to exercise was ?enhance my condition?.
Prognostisering av slitdelar : hur ska Väderstad-Verken öka sin servicegrad?
The agricultural plantingmachines are used just a few weeks every year. That means that the supply of service and spare parts have to be good to make the timeliness costs low at the agricultural hard working periods. The machines wear down successivly when they are used. The wear is harder on some parts than the others on a machine. Spare parts can be dicided into consumables.
Robotstudio för bearbetning
Projektet ProFlexA syftar till att automatisera gjutgodsrensning av stålgjutgods vid lågavolymer genom att använda ny adaptiv teknik såsom flexibla fixturer och gripdon samtkraftstyrning. Projektet bedrivs av Linköpings Tekniska Högskola och Lunds TekniskaHögskola med stöd av tre gjuterier i Mellansverige samt systemintegratörer och leverantörer.Automatisering av gjutgodsresning har länge varit föremål för både forskning ochkommersiellt intresse. Det finns idag fungerande lösningar främst riktat mot aluminiumgodsoch högre produktvolymer.Syftet med examensarbetet var att undersöka huruvida Robotstudio, och mer specifikt desstilläggsmodul Machining, var lämpligt för användning vid gjutgodsrensing. För att detta skallvara möjligt på hårdare material krävs kraftstyrning, vilket finns som tillval i den tidigarenämnda tilläggsmodulen.För att ha möjlighet att testa machiningmodulen och få en uppfattning om vad Robotstudio ärkapabelt till genomfördes först en självstudie av programmet. Som delmål för instuderingengenererades en visuell robotcell enligt ett av ProFlexA:s tidigare koncept förgjutgodsrensning.

Hjälp! Eleven sa svartskalle! : En kvalitativ intervjustudie om hur lärare bemöter främlingsfientlighet i klassrummet.
In a multicultural society such as Sweden opposition between different ethnical groups can be hard to avoid. In the educational arena there is legislation and there are guidelines that aim to avert any kind of xenophobia directed at individuals or groups. As teachers occupy the end point of the educational chain the execution of these guidelines is for the most part left up to them.This paper aims to study how teachers handle situations where xenophobia is present and if so how they work preemptively against it. It also takes a closer look into the notion of professionalism within the teacher force with the aim of trying to answer whether teachers reach the requirements of professionalism. To do so we apply Gunnar Berg?s definition of the term 'professionalism' together with other scholars' thoughts on the subject.
