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.

De internationella klimatförhandlingarna handlar om att hitta lösningar för att stabilisera halten av växthusgaser i atmosfären och att uppnå tvågradersmålet. För att uppnå målet finns olika utsläppsmål att sträva mot. Ett är ett utsläppstak där varje land inte får släppa ut mer än 2 ton CO2-ekv/capita per år för att tvågradersmålet ska uppnås. Ett annat utsläppsmål är att minska de nationella utsläppen med en viss procentsats. EU:s del i minskningen ligger på 80-95 % till 2050.Som en del av arbetet mot målet presenterade EU i mars 2011 en färdplan för ett utsläppsnålt samhälle.

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

The population growth and urbanisation in low-income countries bring issues of poor living standards and miserable sanitation conditions onto the agenda. If well-functioning waste management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities. This master?s thesis project is performed with the intention of developing functional decentralised waste management units in the city of Pune, India.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Modeprodukter har en mycket kort livslängd och modebranschen förändras snabbt. Tiden är därför essentiell och utgör en betydelsefull konkurrensfaktor. Genom att reducera tid i försörjningskedjan kan ett företag vinna marknadsandelar samt höja sin lönsamhet. RFID är en teknik som kan användas för att reducera tid samt förbättra logistiska processer i försörjningskedjor. Trots att denna teknik har börjat spridas, används den generellt inte hos svenska modeföretag.

People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).

The heating of companies premises is today functional with electrical heating and heating offossil fuel. The energy cost for these kinds of heating in buildings has heavily increased duringthe last years and the influence on the environment has become more visual. This leads to thatenterprises today become more anxious to render energy more effective and find alternativesolutions to their ancient heating systems. This is something that Skandinaviska kraftprodukterAB in Halmstad has become aware of.The purpose with this examination is to find the most cost-efficient and environmental measuresfor the office and workshop premises of SKP AB. Where one of the bigger things is to find agood alternative for their current oil furnace, which was heating the workshop.

The veterinary handling of wildlife, both in zoos and in the wild, commonly requires that the patients need to be captured and immobilized for examination or treatment. This emphasises the need for quick, on-site, laboratory equipment, in order to minimize the analysis time and thus the stress for the animal and also in order to increase the possibility of starting relevant treatment early on. The aim of this pilot study was to determine whether Serum Amyloid A (SAA) could be a measured in blood samples from bottlenose dolphins (Tursiops truncatus), Asian elephants (Elephas maximus) and South American tapirs (Tapirus terrestris). SAA rises to its maximum about 24 hours after the introduction of an inflammatory agent in companion animals. This also correlates with the estimated time it takes for animals at Kolmården Wildlife Park to be examined and having blood samples collected after being observed as sick. The study also evaluated whether the Eurolyser SOLO, using a turbidometric immunoassay (TIA) developed for human diagnostics, could be used for such analysis. This pilot study was a retrospective analysis of SAA in convenience sampled frozen serum, collected from dolphins, elephants and tapirs.

Ett vanligt problem för fjärrvärmeföretag är svängningar i den dagliga efterfrågan på fjärrvärme. När efterfrågetoppar sker i fjärrvärmenätet behöver fjärrvärmeföretagen oftast använda sina topplastpannor, vilka vanligtvis drivs på både dyra och miljöovänliga bränslen. Ett sätt att åtgärda detta problem har traditionellt varit att använda en ackumulatortank som värmelager. Men med ny och billigare mät- och styrsystemteknik har kommersiella lösningar börjat växa fram där istället byggnader kan användas som värmelager.Syftet med examensarbetet är att undersöka de tekniska och ekonomiska möjligheterna för att använda byggnader som värmelager i ett fjärrvärmesystem och jämföra det med att använda en ackumulatortank som värmelager. Det förs en diskussion om hur ett samarbete skulle kunna se ut mellan fjärrvärmeföretag och fastighetsägare för att möjliggöra användningen av byggnader som värmelager.

Detta examensarbete utreder lönsamheten i en systemlösning för termiskt akviferenergilager tillsammans med ny VVS-teknisk lösning i fastigheterna kv Hästskon 9 och 12 vid en föreslagen framtida helrenovering. Dessutom utreds förutsättningar för miljöklassning i energi- och miljöcertifieringssystemet Miljöbyggnad avseende energianvändning, dagsljuskomfort, solvärmelast och termisk komfort för om- och tillbyggnadsförslaget med målsättning på nivå GULD.Genom att utnyttja akviferen under fastigheterna kvarteret Hästskon 9 och 12 idag kan man åstadkomma mycket låg energianvändning med en säsongsenergiverkningsgrad via kylmaskiner för värme- och kylaförsörjning på 5,6. En LCC-kalkyl visar att det finns en energikostnadsbesparing för fastighetsägaren Vasakronan omkring 3,65 MSEK per år jämfört med dagens situation om den beskrivna akviferlösningen används. Det ger en återbetalningstid om cirka 4,5 år på investeringen som måste göras. Energiklassning i Miljöbyggnadssystemet för befintliga fastigheter är troligtvis möjlig utan andra åtgärder än akviferlagersystemet, men då med BRONS eller möjligtvis SILVER nivå.Vid ett framtida om- och tillbyggnadsförslag får fastighetsägaren cirka 13 000 m² ytterligare uthyrbar lokalyta för handelslokaler och kontor.
