An Interoperable Fare Management system for public transport has been a struggle for the actors in industry of public transport. A lot of effort has been put into creating a smart card solution that enables the travellers to use the same card for paying and holding the ticket regardless geographical position in Sweden. That project has failed, mostly due to a lack of taking non-technical actors and aspects into consideration during the project process. This thesis highlights the major actors and their responsibilities. The ARKTRANS framework is used as analytical tool to identify different roles. Throughout the thesis a sociotechnical perspective is used. The developed method in this thesis is suitable for mapping of actors and responsibilities in a network surrounding a complex technical system.

Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.

The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.

This thesis was made possible by the company Verendus system AB, which is the leading developer of dealership management systems in the caravan and camper market. The goal of the thesis was to create a statistics module for a new producer system envisioned by Verendus. The new system is aimed at manufacturers and importers of caravans and campers, with the goal of enabling its users to create more effective production lines. By providing statistical data to mentioned users they will be able to predict market trends and customize their production lines accordingly. Today such software does not exist which leads Verendus to think that its arrival would lead to a success on the market.Before the development and design of the producer system began, a new agile method had to be developed, MAM (Minimum Agile Method).

Denna rapport behandlar en prisjämförelse mellan fyra olika elsystem i fyra valda referensmiljöer. Uppdragsgivaren till detta projekt är företaget Arexor som har utvecklat en ellist som de ska släppa på marknaden under hösten och därför vill ha en prisbild på marknaden idag. De olika systemen är i huvuddel Thorsmans TEK-123, KB-systems DWP, Eubiqs PTS samt det traditionella sättet med kablar och VP-rör infällda i väggen. Även en presentation av projektets uppdragsgivare Arexor och deras ETS finns att läsa om. För att kunna utgå från en realistisk bakgrund är referensmiljöerna valda så att en standard kan sättas för utformningen.

Ett företag kan göra sina för- och efterkalkyler i MPS-systemet eller i ekonomisystemet. Hur den ekonomiska uppföljningen är fördelad mellan de olika systemen är helt upp till företaget med avseende på företagets olika behov och krav.Den centrala delen av detta examensarbete är de besöksintervjuer som genomförts på fyra utvalda företag. Dessa intervjuer ligger till grund för mitt resultat och analys. Utifrån det insamlade materialet har jag besvarat den frågeställning jag hade: Hur hantering med för- och efterkalkyler sköts samt hur ekonomisk uppföljning är fördelad mellan MPS-system och ekonomisystem.Det resultat och slutsatser som jag kommit fram till finns presenterat i denna rapport. Det visade sig att de undersökta företagen sköter arbetet med förkalkyler noggrant.

Arbetet är ett examensarbete i högskoleingenjörsutbildningen, inriktning datateknik, på Linnéuniversitet. Arcoma AB är ett företag i Växjö som utvecklar och tillverkar kompletta röntgensystem. Företaget har som mål att förbättra användarvänligheten av systemet med hjälp av en LED-display. De kan förbättra systemet genom att byta ut en enhet som styr röntgengeneratorn mot LED-displayen. Detta leder till att användaren får bättre kontroll och styrning av systemet, samtidigt som patienten behandlas.I rapporten beskrivs implementering av både hårdvara och mjukvara till displayen, samt den tekniska bakgrunden som till exempel HDMI och LED-tekniken.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

This master thesis is made of two parts. The first part concerns the method and results ofdesigning a motion control system for a piece of research-equipment called BIRGIT. Theequipment is made to be used for research on eyemovements. In the second part, a computermodel of a part of the balance organ in the inner-ear is developed. The work has been done atthe Bernadotte laboratory at S:t Erik Eye Hospital.The equipment the control system is made for is a so-called rotationchair.

The forestry companies? operational planning process is these days dependent on reliable, efficient and user-friendly computer-based support systems. This study is an evaluation of Holmen Skog's current computer-based systems. The aim of this study is to: ? investigate the work pattern of the production managers when using the information system to plan the harvesting operation; ? investigate the efficiency and user friendliness of the information system with the different work patterns and to find the strengths, weaknesses and bottlenecks in the current system; ? find out if the type of object, the volume, the area of the harvesting object affects the time and work pattern; ? examine how this type of study is met by the employees and what factors that is critical to avoid feelings of intrusion. The conclusions of the study were: ? there is a large variation between the work patterns of the production managers and the time spend to perform the operational planning; ? the mainframe computer system used by Holmen Skog is clear, has short response times, is robust and conveys relevant information; ? the computer systems are however divided in many subsystems.

In Europe, the central governments are the ones to coordinate the international standards and strategies regarding GPP; Green Public Procurement. However in Spain a GPP program was introduced late and only applied to the Central Government Institutions, (AGEA) (BOE nr. 027, 2008). These means that smaller administrations, such as, Autonomous Regions, Municipalities and Town Councils were not included in the program. The absence of a national program which excludes those governments made them introduce their own criteria for GPP, and the difference in criteria varies from one government to the other.

A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.

WebGL is a standard for drawing graphics in a web browser. Currently it isn?t widely understood how consistently WebGL performs across a majority of the de- vices that support it. Determining if an image looks correct to a human observer is an interesting problem. The solution for this is useful when developing WebGL applications, since a developer could make better informed decisions during de- velopment.
