This master thesis studies distributed Navigation which isa function implemented in a future network based combat information system to improve the accuracy in Navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the Navigation worse. The distributed Navigation function uses position and Navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed Navigation, a simulation environment has been produced in Matlab.

The purpose of this paper is to explore web use and web Navigation behavior. This paper presents findings from qualitative research based on interviews and diarie studies. The basis of this study is Eli Parisers work about ?the filter bubble?. As personalization systems shape our experience of the web, based on who we are, our bubble of knowledge and information becomes smaller.

The purpose of this study is to examine which aspects of blogs and blog design that are important to blog readers but also to find new ideas for blog design. From a qualitative standpoint we have examined how seven users experience that blogs design, structure and functionalities affects the general experience of the blog. The study also examines how the users wish to interact with a blog. During two design workshops we let seven active blog readers imagine and sketch out the design and functionalities they would like in a blog. We put this in relation to theories about the anatomy of blogs, methods of design, social Navigation and virtual communities.The major finding is that the aspects most important to blog readers are Navigation, structure and social interaction.

Visuella vägledande element kan höja eller sänka en spelupplevelse. Därför har vi gjort en studie kring hur man kan uppnå intuitiv visuell Navigation med fyra beprövade visuella vägledande element, nämligen ljussättning, färgkulör, färgmättnad samt objektplacering. Dessa element har använts för att skapa ett visuellt språk i en bana som vi har låtit ett antal respondenter spela och simultant kommentera. Resultaten har varit som väntat, att ljussättning fungerar som det starkast vägledande elementet, samt att respondenterna reagerade på, samt vägleddes av, nämnda element..

Today, we can see that social Navigation is embedded in different kinds of websites, but there is still little support for social Navigation in the web browser. Our main concern has been how we construct a tool that fills this hole in the web browser. By letting the theory, the prototype and the focus group serve as input/output to each other we could create a better overview of how the different pieces were intertwined. This has been a crucial mental model for us to obtain since it has helped us to understand how we could realize the theory through our prototype and thereby come to the conclusion of what aspects of the theory that we should put forward to further development. After constructing the prototype we thought that it would support social Navigation, but realized after analyzing the discussion of the focus group that we are not there yet.

The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial Navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.

Navigation är ett centralt begrepp i spelanvändning, trots att det ofta ses som ett nödvändigt ont. Det här arbetet intresserar sig för upplevelsen av Navigation i två typer av programvara ? spel och nyttoprogram. Detta arbete går ut på att granska hur upplevelsen av Navigation i programvara är beroende på användarnas förväntningar ? om användarna tror sig använda programvara för nytta eller för nöje.

C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing Navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.

This is a study that was conducted during a three day exercise of the Swedish Armed Forces called ?Amfibieförbandet?, which is shortened as AMF, in Gothenburg. During the exercise three scientists followed the crew on the boats and this is one of the studies that became the result of the observation made during the exercise. The boats that was used during the three days were the boat called ?Stridsbåt 90H? by the Swedish armed forces.

This thesis explores different ways of Navigation in virtual environments. It also investigates how virtual environments can support human memory. Tests are done using a self made virtual model of Orkanen Library, Malmö högskolas school library. Among the different Navigation tests that were done, a visual guidance in form of a line on the ground leading to the goal is showed superior when navigating a virtual environment but that people prefer legible landmarks instead. Tests were also done which show that a 3D-model of a real location supports context based memory.

This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a Navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.

Detta arbete har utförts i samarbete med företaget Compute och fokuserar på att utveckla Navigationsstöd för webbportaler med bokningssystem. Arbetet har delats upp i tre specifika mål: (1) integrera Information Foraging Theory (IFT) och Graphical User Interface principles (GUI-principer) genom att applicera dessa vid utvecklng av Navigation för webbportaler med bokningssystem (2) konkretisera hur navigering kan förbättras på en webbportal med bokningssystem, utifrån ovanstående teroier och (3) arbetet skall resultera i en lista med rekommendationer som kan tillämpas vid utveckling av Navigation. För att kunna  integrera IFT och GUI-principer har dessa i kombination med en teroertisk studie tillämpats vid prototyping. Prototyperna användes som verktyg för att konkretisera hur Navigationen kunde förbättras på portalen. Prototyperna utvärderades och resulterade i en lista med rekommendationer.

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

The annual cost of home care services of transport in Falun/Borlänge, is now at 31 million kronor. It is clear from previous research that it is possible to reduce these costs through a restructuring of the existing home-help service. The restructuring aims to have a higher proportion of older people, who are in need of care, to live in special accommodation, in order to reduce transport costs. Therefore there is a need for systems that allow home-help service to plan their operations in such a way that transport is working as efficiently as possible. Through better planning, there are profits to be done.
