This master thesis investigates the possibilities of using GPS-information from trains to create a model of a railway system, register the routes of the the trains and predict how the trains will travel in the railway system.The thesis work was done at Icomera AB which is a company that specializes in internet connected vehicle solutions.We describe how the GPS-information is sent from the trains in the form of samples and investigate limitations and possibilities with the available information. About three million samples from 83 SJ-trains were analysed and the samples were filtered with the intent of removing erroneous information. We here found that about 30 % of the samples from the trains were unreliable.A solution for how the samples from the trains can be used to create a model of the railway system traveled by the trains is presented. We use a large set of historical samples and use cluster nodes and Hermite curves to generate a graph that represent the railway system with stations, nodes and the railway itself. A fully automatic solution is not presented since it did not fit into the time frame of the thesis; instead we created a simple tool which can be used to manually finish the model of the railway system.Furthermore, we describe how the railway system and the samples from the train can be used to register the routes the trains travel.

Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

Students at Jönköping School of Engineering were given an assignment from Jönköping municipality, to evaluate their decision support system, QlikView. The students have also developed proposals for improvement with focus on usability.The Jönköpings municipality has currently got 11000 employees and consists of nine different administrations. The target group for QlikView is approximately 600 first-line managers.The intention of QlikView is that the users can get an overall picture of their business by having all information in just one system.The purpose of the thesis is to obtain a picture of what the users think about the system today and present relevant suggestions for improvement, which the Jönköping municipality can use when the introduction of the new version of QlikView takes place. The research questions that the study aims to answer are:? Has QlikView got a user friendly interface?? How can the interface be improved to become more user friendly?Theories that this work is based on is Jacob Nielsens ten usability principles and Ben Schneidermans eight golden rules.

I denna rapport har vi undersökt om och hur faktorer i människa- datorinteraktions teori påverkar användandet av ett datalager. De faktorer vi undersökt är informationsbehov och användbarhet. Användbarhet innefattar användarvänlighet, användaracceptans, användaranpassning samt användarkompetens. Då ett datalager lagrar data som samlas in från verksamhetens övriga system finns möjligheten att söka information direkt från källdatabaserna istället för från datalagret. Detta var fallet för slutanvändarna vid Norrbottens läns landsting.

In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.

I denna uppsats undersöks huruvida HPM (High Power Microwaves) kan användas som enverkansform i framtida luftvärnssystem för att bekämpa kryssningsmissiler. Studien undersökervilket hot kryssningsmissiler kan utgöra, hur de är konstruerade och hur HPM kan påverka dem.Uppsatsen redogör för hur det nya luftvärnskonceptet är uppbyggt och vilka krav på förmågor somställs på framtida luftvärnssystem. Den undersöker även hur ett HPM-system är uppbyggt ochvilken verkan det kan ha på elektriska system i en kryssningsmissil. Vidare diskuteras vilkeneffekt tre olika HPM-system kan ha mot kryssningsmissiler kopplat till de krav som ställs iluftvärnskonceptet.Huvudslutsatsen indikerar att HPM-system kan ha verkan mot kryssningsmissiler. HPM-systemkan nyttjas främst i scenarier där det ställs höga krav på eldhastigheten mot kryssningsmissiler påkorta avstånd.

The purpose of this Master thesis is to examine theinformation use and information seeking behaviour amongpersons who actively work with information. For this study,interviews have been conducted with a group of six personswho work with information in information intensiveorganizations. The aim is to answer the following questions:What kind of information is connected to the respondents?work tasks? What is the purpose of their search forinformation? Which information sources do they use and whatkind of information sources do they demand? The theoreticalframework consists mainly of Wilsons information needs andinformation seeking model.The results of this study show that none of the respondentshad any strategic model for their work with information. Theinformation that the respondents were searching for is ofdifferent content and depends on the organization in which therespondent operates.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

This thesis project has been written and accomplished in cooperation with HABO AB. The objective of the project was to develop a standard stated packaging system. The background to this is that HABO is not pleased with the system currently in use. The system which HABO is currently using consists of to many sizes. The largest benefit of a standard stated system is that it becomes much easier to organize the packaging with the aid of a computer program.
