Välfärdseffekten av en konkurrensutsatt tågmarknad
The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.
Möjligheter och begränsningar i molnet
Idag väljer många företag och kommuner att placera data i molnet istället för på en lokal server, detta medför nya problem som tidigare inte varit aktuella. Datainspektionen har påpekat brister i hur två kommuner använder molntjänster för att lagra personlig data då de ställer sig tveksamma till molnleverantörernas hantering av data samt insynen till molnleverantörerena. I detta arbete kommer det undersökas hur den svenska personuppgiftslagen fungerar när data läggs ut i en molntjänst. Resultatet av uppsatsen kommer även visa på de olika säkerhetshoten som finns i molnet och se vad säkerhetsexperter säger för att ta reda på om kommuner och företag är medvetna om och uppmärksammar samma hot. För att ta reda på detta har intervjuer genomförts med en svensk molnleverantör, företag som utvecklar tjänster mot molnet, privatpersoner som nyttjar molnet och experter inom säkerhet från Blekinge Tekniska Högskola, BTH.
Den moderna kommunikationen : En rapport om instant messaging och hur det används av unga vuxna studenter.
This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.
Effektiv datahantering för simuleringsbaserad ruttoptimering
Det här examensarbetet undersöker hur en databaslösning kan utformas för simuleringsbaserad ruttoptimering. Då det finns få relaterade arbeten inom ämnet syftar detta arbete till att undersöka hur en lämplig databaslösning kan utformas och ge riktlinjer för detta. Databaslösningen innefattar både lagring av data samt åtkomst och hantering av data. Då simuleringsbaserad optimering ofta är avancerad innebär detta att en stor och komplex mängd data måste hanteras. Simulator och optimerare använder denna data under själva optimeringsprocessen, vilket ställer krav på effektivitet och snabb åtkomst. Arbetet är inriktat på ett praktiskt problem där sophantering av containrar simuleras och optimeras.
LCC-kalkyler i byggbranschen : förutsättningar och tolkning av resultat
Background:Life-cycle costing (LCC) is an investment calculation that takes intoaccount operating costs throughout the investee lifecycle. LCC calculations are mainly usedto evaluate investments that have no revenue side. Attempts to apply the LCC calculations forbuilding-related investments have occurred since the 1980s. Despite the advantages ofusing LCC calculations, use has not passed through in full. The main obstacles have beenidentified as a lack of relevant input data, and insufficient experience of workingwith LCC calculations.
Observiaire och film som analysmetod för cykeltrafik : En fallstudie på Götgatan i Stockholm där omställningen till supercykelbana utreds
The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.
Gröna miljöer på skolgården : som plats för utomhuspedagogik
School ground development is becoming increasingly popular in Sweden today and local community settings are also seen as an important resource for education. The debate today raises the question about the whole city?s pedagogic potential. Outdoor education is a pedagogy that comprises outdoor learning with focus on the sensual experiences. Connection to the classroom education is an important part of the pedagogy and so is the place for the tuition.But how should the place for the tuition, i.e.

Bearbetning av GPS-data vid Flyg- och Systemprov
At Flight and Systems test Saab AB, a post-processing software is used to process GPS data. A new software by the name GrafNav has been purchased and the purpose of this master thesis therefore became, partly to make a judgment regarding GrafNav?s ability to estimate position, velocity and accuracy, partly to if needed improve the estimate and finally find one or several methods to estimate the position and velocity accuracy. The judgment of GrafNav was performed partly by a comparison to the former post-processing software (PNAV) and partly by a comparison to the airplane?s inertial navigation system (INS).
Insamling av data från en linjär bildsensor med bearbetning i LabVIEW
Insamling av data med hjälp av en linjär bildsensor, I/0 modul och LabVIEW i realtid för analys.Uppgiften innefattar val av skanner och I/O modul samt utvärdering av den insampladeinformationen. I rapporten beskrivs det också hur olika enheter synkroniseras med varandra..
Framtagning av korrigeringsfaktorer för enhetstider och kapaciteter : Ett sätt att öka kvalitén på Skanskas normallägen.
Skanska is using work schedules that are specifically designed for employees in the production. These work schedules are called best practice. These are guides containing technical descriptions, design references, capabilities, etc. for work activities. This support function facilitates the work preparation and planning of future work.

Working Caital Policy : Ett sätt att driva verksamheten
The working capital describes the short-term financial position and focus on cash flow and the actual inflow and outflow of money in the company. Working capital is part of the company's financing and consists of the company's current assets and current liabilities. There are resources that are used in the daily activity and can be optimized. The more effective they are in circulation, the higher value they create. The control of working capital is called Working Capital Management and has its basis in the company?s Working Capital Policy.
Deterministisk Komprimering/Dekomprimering av Testvektorer med Hjälp av en Inbyggd Processor och Faxkodning
Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.
Luova. En föränderlig sittmöbel för det offentliga rummet
The aim of this project was to design a furniture that raises thoughts and curiosity about how to relate to people you share furniture with. Luova, a changing piece of furniture for public spaces is a bench where the user can choose the degree of social interaction. Furniture for public spaces has a diverse audience ranging from children to adults. Some come alone, others in group. Some are sitting down for a short time while others stay for longer.
