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.

The National Libraries task to save and preserve the national cultural heritage has turned to a new challenge in a digital world. The preservation of born-digital material for future use requires not only saving the digital object itself but also information about the object, preservation metadata. This is a relatively new issue and the library community has very little experience in this area. It has become evident that international cooperation is necessary to solve the task and that the development of international standards is of fundamental significance. This thesis investigates what has been done to meet the problems with the fast obsolescence of digital material with the focus on metadata.

Abstract During object-oriented system development, programming should be preceded by analysis and design to assure that the system fulfils the demands of the customer and simplify during the development phase and documentation. When modeling the analysis and design phases, several different notations may be used. One of these is the UML (Unified Modeling Language) which this thesis will cover. The aim is to compare the use of the UML i practice versus what is said in the literature. The investigation is built upon interviews at different companies to receive their reflections about the UML.

Social enterprises make up one of the groups of participants that provide welfare services financed by public funding. The object of this study is to describe and analyze from a theoretical point of view which conditions, in what fields, by which division of responsibility and finally through what decisions these social enterprises are allocated a place in the market for social welfare services. The company that has been the object of study offers services in the field of social welfare and in employment. In the study a triangulation of qualitative methods has been used: studies of literature on the subject, recurrent interviews and observations and also reviews of documents. The results have been analyzed from theories on the space available on the market for social services, on social economy and on social capital in the form of strong, weak and bridging bonds.

This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region. For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn. It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams. The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient. One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..

When different type of programs are developed one wants to make these adjustable to future changes and requirements. It must be done a good design of the program from the beginning to make it possible to continue development of it without having to redo big parts of it to high costs. In the area of object orientation there are design pattern, which can be used to design systems that can be adjusted to new changes in an easier way. I have in this thesis chosen to take a closer look at how to design a program that sends SMS to cell phones through a system of an operator. One requirement on the program is that it has to be possible to change what operator to send though in an easy way.

The goal of the project was to create an extension to Internet Explorer forStatens Tjänstepensionsverk (SPV) which would give the staff the experience ofSingle sign-on (SSO) to external web service providers as well as manage andupdate their passwords in a secure manner. The survey focused on the providersPalasso, ProCompetence and Wera. The extension was created as a BrowserHelper Object (BHO) with C# in .NET. The solution was implemented as aCOM object in a DLL-file that was running in-process with the browser. Theprogram used a locally stored XML file containing URLs, usernames andencrypted passwords to the providers.

 Purpose/Aim: The goal of this thesis is to examine access and knowledge computers and the Internet among the senior-year students of Anacostia High School. Do the students of this facility have the same opportunity as the residents from better socioeconomical backgrounds or are they being excluded from the technology? Material/Method: To approach the thesis goal I have used a quantitative method. More specifically, a questionnaire was handed out to the senior year students at Anacostia High School. Main results: The study has shown that most of the students of Anacostia had in some way access to computers and Internet.

As we dwell in the northern part of Europe, we who livethrough its gloomy winters need to find shelter in the warmthof our homes which cater to our well being. The object ofthis project lies in designing both a flexible, sturdy, and reliablepiece of furniture that yields to one?s intrinsic needs.The aim is to offer a piece of furniture that induces suchcomfort and exudes a feel good haven and refuge to each andevery one of us..

The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background. This study shows that the dog ERG has both ON- and OFF-responses and that these responses can be separated by prolonging the flash duration over 50 ms. The dog OFF-response waveform was more similar to the cat OFF-response than the human OFF-response (Frishman, 2006; Zrenner and Gouras, 1979). In this study six female three-year-old Beagle dogs were included. Both background and flash stimuli were provided by LEDs (light emitting diodes) with a wavelength of 470 nm, a wavelength that is absorbed almost as effectively by the canine M/L-cones as by the S-cones. These stimuli gave ERGs with both ON- and OFF-responses.

The object of this essay was, first, to study what advantages parliamentary members in the participating countries argue that their country gains when university students study abroad via ERASMUS, and, second, to study two factors that might affect what advantages that are emphasised by the parliamentary members in the participating countries. To achieve this object, two research questions were posed regarding what advantages of the ERASMUS Programme are mentioned in the parliamentary debate in three countries, United Kingdom, Sweden and Germany, and regarding whether the parliamentary debate is different between the countries as concerns what advantages are emphasised. Subsequently another two research questions were studied, regarding whether the countries? different positions in Europe and the existence of euroscepticism in these countries affect what advantages of the ERASMUS Programme are emphasised in the parliamentary debate. The study was carried out using argumentation analysis, in which the arguments for participation in the ERASMUS Programme presented in the parliamentary debates were compiled and grouped together according to whether they refer to economic and professional advantages or to cultural and social advantages.

I want to, but how? My work is a research of the creative process. I have asked myself how ideas take form and how materials can become bearers of ideas. The work has been treated as an action rather than an object. The result shows my research and my interpretation: the process and result are the same..

Hästen är ett stäppdjur som under en lång tid utvecklat sin flyktinstinkt samt specifika beteendemönster som spänd kroppshållning och fnysningar. Dessa beteendemönster visar sig vid rädsla och har som funktion att varna artfränder för möjlig fara. Utvecklingen av ovanstående beteenden har haft en stor betydelse för artens överlevnad. Att snabbt fly från saker som hastigt dyker upp i synfältet, är hästens främsta sätt att skydda sig mot fara. Flyktinstinkten har haft så stor betydelse för hästens överlevnad att den inte går att träna bort. Hästens flyktinstinkt ligger ofta bakom flertalet av alla hästrelaterade olyckor som sker.
