The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.

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.

This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.

The goal with this master thesis has been to evaluate and to examine the stationary resistance bridge. The resistance bridge uses a 4-point measuring to determinate the resistance, which is used in the manufacturing of the conductor. It is then used when the resistance is to be decided for coarser aluminium conductors. A conductor has to fulfil certain demands to be able to move forward in the process. One of these demands is the resistance in ohm/km, which has demands that the measure values of the resistance bridge are as true and precise as possible.

The stationary resistance bridge had been examined through various kinds of measurements to be able to see how stable the system is and how to obtain a measure value as optimized as possible.

This thesis deals with past and present political attitudes towards the Öresund bridge. It describes the decision making process which preceded the construction of the bridge, and has a short historical introduction to it. It then presents the attitudes towards the bridge of five different political parties, all represented by regional politicians. This empirical information was obtained through interviews with politicians and literature studies. The author then analyzes the empirical information with the help of the human ecological triangle developed by Steiner, and the center-periphery theories of Wallerstein and Persson.To conclude, the author describes what the central problem is in the case of the Öresund bridge from a human ecological perspective and analyzes the empirical data collected..

This report is a thesis for collegeengineering program in structuralengineering at Uppsala University andwas commissioned by the Swedishcontractor Svevia. The study aims toprovide an overview of the mostbeneficial bridge material from bothenvironmental and economic point ofview.The life-cycle analysis covers onlycarbon dioxide emissions, since it isthe most spoken of in today?s climateagenda. Furthermore, this study aims tohighlight which parts, of the systemboundary, that contributes to greatercarbon emissions for the wood- and theconcrete bridge.The life-cycle cost analysis wascalculated with a lifespan of 40 yearsand covers the basic cost of investment,operating and maintenance, anddecommissioning costs.The analyzed constructions in this studyare existing projects that are almostcompleted. Both bridges were designed tohandle loads up to 60 tons.

The accounting information system comprises budgeting, accounting, and costing. The accounting information system has, traditionally, constituted an integrated system where the different elements collaborate. If ABC is introduced this order is disturbed, since ABC is based on another logic which cannot easily be integrated with budget and accounting. ABC, therefore, is usually used parallely to the conventional costing method. There are, however, companies that have taken its ABC one step further by letting it replace the old costing model and integrate it with the accounting information system.

Ombord på moderna fartyg finns möjligheten att navigera med enbart ECDIS. ECDIS är beroende av många olika delsystem för att kunna fungera optimalt.Failure Mode and Effect Anylysis (FMEA) är ett verktyg med vilket man kan undersöka ett specifikt system för att upptäcka eventuella konstruktionsfel och brister i produktionsdesignen. Detta examensarbete har med hjälp av en FMEA undersökt ECDIS simulatorerna vid Sjöfartshögskolan i Kalmar för att ta reda på hur ECDIS påverkas när ett eller flera av delsystemen kopplade till ECDIS fallerar. Syftet med denna undersökning har varit att upptäcka konstruktionsfel, brister och begränsningar i ECDIS systemet vid simulatorerna i Sjöfartshögskolan i Kalmar. Det kunde påvisas att ECDIS i vissa fall ej har avgett de larm som enligt tillverkaren skall varsko navigatören att ett delsystem har fallerat.

The Swedish Transport Administration manage nearly 4,000 railway bridges in different condition and age around the country. These bridges is in constant need of maintenance and requires continuous inspections. This thesis is designed as a damage investigation on a single-track railway bridge south of Solvarbo in Säter municipality. The railway bridge is in operation and serves over 10,000 trains a year, everything from speed trains to freight trains. The bridge is built as a beam bridge, simply supported over a road.
