With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

Cover Story is a project, which students at Lillholms - and Ekholms School worked in during spring and fall of 2009. Several school subjects were integrated in project; social studies, art and Swedish, to empower the students to create, implement and design a magazine. The purpose of the project was to give the students the opportunity to fantasize about the future and their dreams by creating their very own Cover Story. During the project I realized that the student?s selection of magazine genre had a direct relation to the gender of the students themselves.

The purpose of this report is to evaluate different methods for identifying states in robot models. Both linear and non-linear filters exist among these methods and are compared to each other. Advantages, disadvantages and problems that can occur during tuning and running are presented. Additional measurements from accelerometers are added and their use with above mentioned methods for state estimation is evaluated. The evaluation of methods in this report is mainly based on simulations in Matlab, even though some experiments have been performed on laboratory equipment.The conclusion indicates that simple non-linear models with few states can be more accurately estimated with a Kalman filter than with an extended Kalman filter, as long as only linear measurements are used.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

In this investigation has an attempt to find out whether so called transplanting shock depends on the moving and transplanting of trees, to other conditions, or if it is due to the imbalance between the root to shoot ratio. Seventy trees of Prunus avium have been part of the investigation and these trees have been divided into four different groups depending on methods of production, untouched on the field, trees still on the field but with root pruning, trees moved and planted into Root-Control-Bag, trees moved and planted into Spring-rings. To be able to answer the question, measurements of the length of the terminal shoots and the lateral shoots and the dimension of the stem growth have been done and also has a visual judgment of the trees vitality been performed. The result shows that it is not only the move of the trees that gives them transplanting shock, but rather the loss of roots which gives an imbalance between the root and crown..

In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.

ABSTRACTTitle: Elle & Café ? a study of fashion magazines cover pages.Number of pages: 38Author: Greta SimonssonTutor: Amelie HössjerCourse: Media and Communication Studies DPeriod: Spring Semester 2008University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The purpose of this essay is to:? Analyze the cover images from the 2007 editions of the magazines Elles and Café, using semiotic analysis.? Analyzes eventual resemblances or differences between the two magazine's cover images based upon the result of the semiotic analysis.Material and methods: The study of Elles's and Café's cover pages has been done using a model built upon semiotic analysis, developed with the purpose of suiting observation and examination of cover pages of fashion magazines. The cover pages were analyzed from the categories character, context, and environment.Main results: The main results include the observation that both Elles and Café chooses well-known figures from women's fashion industry as prime characters on their covers. In Elles, all main characters are famous women emerging from the music, television and fashion industries. The women in Café are known for similar professions.

During the time between 1660-1680 the nobility in Sweden came to be a gigantic landowner with 65 % of the total amount of land, but only 20 years later they lost almost half of their possessions. The eighteenth century was on its way ? a period in history were ?ordinary? people started to question the nobility?s right to be excused from tax, at the same time as farmers and the ?middlegroup? started to appropriate more and more land from the nobility and the Crown.Through King Gustav III:s document of 1789, land became free to own to whoever it was ? except from the prime nobility?s land; but the Swedish Parliament followed the wind of change, and 1809/10 this land was also free to own. At the end of 1840, the nobility owned about 19 % of the land in Sweden, and the farmers and middlegroup owned 69 %. The tide had turned...But Öja parish showed a different development compered to the rest of Sweden.

Upon marketing the system in Europe and the USA cost savings generated from reduced work force have been prevailing. Since the cost of labour is much lower in the Asia Pacific region other factors have to be stressed. The parameters of flexibility and quality assurance may however cover any initial investment in a production system. Our purpose is to value flexibility and quality in a manufacturing context, applied to DAS, in order to use it in investment calculations. In order to make an adequate estimation of different companies, due to problems associated with acquiring correct figures, the Key Success Factors needs to be examined so that the gathering of numbers can be conducted with more focus.

This thesis is a report of the practical aspects and the problems of classification and documentation of a collection of memorabilias from the Crown Princess Couple's Wedding in Stockholm 2010. The collection contains 38 objects collected by Nordiska museet [The Nordic Museum], Sweden's largest museum of cultural history. Nordiska museet has a total collection of over 1,5 million items collected since 1873. My ambition in this thesis has been to describe my work with the classification and documentation of these new objects and their context. One of the main problems was how to combine the modern objects with the old existing collection within the two classification systems used at the museum.

På grund av ökad urbanisering och exploatering av grönområden i stadsnära miljöer fragmenteras och reduceras arters habitat vilket bland annat ligger till grund för den globalt minskade biologiska mångfalden. För att stärka och förbättra arters möjlighet till spridning i landskapet, och därmed säkra en hög biologisk mångfald, efterfrågas insamling av data och utveckling av nya metoder för att identifiera ekologiska kärnområden och för att analysera habitatnätverk. Syftet med den här studien är därför att 1) kartera och sammanställa biotoper i en biotopdatabas utifrån tolkning av infraröda flygbilder med digital stereofotogrammetri, 2) undersöka olika metoder att samla in data med hjälp av laser- och höjddata, och 3) att tillämpa landskapsekologisk analys på underlag i biotopkarteringen.Resultatet validerar att tolkning av infraröda flygbilder med digital stereofotogrammetri är en utmärkt källa för att kartera biotoper som medför en tolkningsnoggrannhet på 86 %. Valideringen av kateringen genomfördes med fältkontroller som utvärderades i felmatriser. En metod har även undersökts baserat på tidigare studier för att uppskatta busk- och krontäckning med hjälp av laserdata, men eftersom det saknas validering av resultatet bör den användas som en indikator för att visuellt uppskatta busk- och krontäckning i dagsläget.

Bakgrund: Inom investering förekommer ett flertal tumregler och myter. En myt som cirkulerat bland investerare är att framsidor i branschtidskrifter, benämnt Cover Stories, skulle utgöra en indikator för en contrarian strategi. Våren 2007 presenterade den första studie där det undersöktes om Cover Stories hade utgjort indikatorer för enskilda företag i USA. Vi kommer att undersöka om Cover Stories i Affärsvärlden och Veckans Affärer utgjort en indikator på den svenska marknaden under tidsperioden 1987 till 2006. Utfallen av våra resultat kan eventuellt bidra till att investerare inte fattar beslut utifrån en felaktig myt om samband inte kan påvisas.

Feline Odontoclastic Resorptive Lesions (FORL) is a painful disease that affects feline teeth and that is increasing in prevalence. The ethiology is still rather unknown. However, research on the ultra structure of the feline tooth may help us understand why FORL is so prevalent in cats and not in other species. Since the ethiology is still unknown, there is yet no profylaxis. The pathogenesis is rather well known; the hard structure of affected teeth gradually undergo odontoclastic resorption and resorptive lesions are often partly replaced with bone- or cementum-like tissue.

Studies show that activity based costing (ABC) is not widespread in practice even though it has been present in the academic world since the 80's. This thesis examines the reasons for the discrepancy between theory and practice through a case study of a Swedish manufacturing company. The intension is to answer the question of what contributes to the choice of precision in product costing.We found arguments for increasing precision in product costing but not to the extent of a full-scale ABC implementation. The company's estimation of the value of increased precision. In the study three company unique factors were isolated that affected the company's estimation of value; drifting purpose of product costing, historical use of product costing and knowledge about product costing..
