This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

In Dar es Salaam, as in many cities in developing countries, green areas are decreasing due to the fact that the growth of buildings, infrastructure and services has become a priority. As the population increases more buildings and infrastructure are needed and much of the building activity takes the form of uncontrolled settlements, which encroaches the public green space. Dar es Salaam has approximately three million inhabitants, of which about 70 percent are living in informal settlements. The aim with this study is to make a design proposal for a park and recreation area where the Msimbazi river basin in the centre of Dar es Salaam is today. The basin consist of a few playing fields, footpaths and some urban farming, but apart from this it mostly consists of unused grasslands, swamps and forests. Because it is an unsafe place and badly connected to the rest of the city infrastructure, it has become a barrier. The annual flood combined with the constant still shallow water creates a good breading ground for malaria mosquitoes.

The purpose with the study was to find a pattern in the behaviour of dairy cows which could be related to their social rank. A behavioural study was conducted at the University Cattle Research Centre (Kungsängen) in Uppsala, Sweden. The study included 12 lactating dairy cows, 6 high ranked and 6 low ranked. The cows were housed in a loose housing barn with an automatic milking system (AMS) to which they had access 24 hours a day. During the experiment the total number of cows in the barn was 46.

Friytande bilpooler tillåter envägsresor med start och slut vid vilken parkeringsplatssom helst inom ett avgränsat driftområde, vanligen en stadskärna. Till skillnadfrån traditionella bilpooler, vari bilar alltid ska återlämnas där de hämtats, finns riskatt fordon blir olämpligt fördelade. Driftoptimering genom dynamisk prissättning utvecklades i detta arbete med målet att möjliggöra ett kostnadsffektivt sätt att säkerställa tillgänglighet av fordon, och därmed lönsamhet, i friytande bilpooler.Två modeller för dynamisk prissättning utvecklades, samt implementerades i en prototyp av en IT-lösning för friytande elbilspooler. Grunden till den första modellenutgjordes av en verifierad modell för kostnadsminimering av stationsbaserade bilpooler med envägsresor. Modellen är baserad på MILP och hämtades ur Alvina Keksavhandling Decision support tools for carsharing systems with exible return time and stations (2006).

Wind is used as an energy source all over the world. To be able to use this effectively, there is a need for as good forecasts and forecast models as possible. One of these models is Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®) that is used to calculate short time forecasts. This model is used here to calculate wind speeds at two different areas in Västra Götaland, Bengtsfors and Vänersborg. There are also wind measurements with SODAR stations for these areas.

Problemformulering: Järnvägstransporter av gods har på senare år tappat storamarknadsandelar till vägtransporterna. Orsakerna är många, enav dem kan konkretiseras till en betydande envägstrafik vilketär en direkt följd av dålig lastsäkringsutrustning i vagnarna.Målsättning: Målet med projektet är att utveckla ett koncept för ny typ avlastsäkringsutrustning som kan integreras till befintligvagnpark. Utrustningen ska alltid finnas i vagnen och hamöjlighet att lastsäkra flera typer av produktflöden menframförallt palleterat gods.Förutom grundläggande krav på hållfasthet för de krafter somuppkommer vid rangering och transport ska utrustningensamtidigt vara så liten som möjligt både vad gäller vikt ochvolym.Metod: Projektet är i grunden en produktutveckling vilken består av enstegvis utarbetad modell av Ulrich och Eppinger när välproblemet hade identifierats. Dessförinnan krävdes dock ennormativ studie för att klargöra de problem som åligger ochsom behöver lösning. Informationsinsamlingen har framföralltbestått av kvalitativ data av både primär och sekundär karaktär.Slutsatser: Författarna anser att en förändring i dagens konservativabransch är önskvärd för att stärka järnvägens konkurrenskraft.Integrering av författarnas lastsäkringsutrustning skulleinnebära en stärkt marknadsposition för järnvägens roll somgodstransportör.

Problem StatementAfter the hurricane Gudrun in January 2005 EON Elnät Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk.Additional new transformers, more than planned, have been bought. This is due to the dysfunctional transformer flow from the demolished power supply to projects, were the new power supply is built, the general picture is complicated, since the reconstruction involves other companies and many employees at E.ON.PurposeThe purpose of this master thesis is to map and understand the existing transformer flow. The objective is to make a recommendation on how to increase the level of E.ON? s transformer recycling.Methodthe authors have worked with a system approach, including both qualitative and quantitative data.

Several technical solutions are ready to step forward as the new generation of propellant, and this report aims to explore the possibility of commercializing fuel cell cars. The report is based on current research and data from today's technology and engineering solutions that are estimated to be commercially realized before 2020.A mapping of today?s different fuel cell options has shown that the most suitable fuel cell option is the Proton Exchange Membrane Fuel Cell, which uses hydrogen as fuel. The report is focusing on a techno-economic well-to-wheel analysis of hydrogen and the energy balance and costs in a system perspective. The basis for this analysis consists of two centralized methods of production, steam methane reforming (SMR), and alkaline water electrolysis.

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.

The Swedish market for vehicle inspection is re-regulated since June 2010. More than four years after the re-regulation there are eight companies in the market. Two of these companies are a result of the former monopolist's owners divided the business among themselves. The remaining six companies have entered the market through acquisitions or by building up their business from scratch, these are known as new entrants in the study. The competition has developed slowly and the former monopolist still has the highest market share.

Målet om ett långsiktigt ekologiskt hållbart Sverige kan inte nås utan en hållbar transportpolitik och infrastruktur. Järnvägen ses generellt som ett mer miljövänligt transportslag och ett ökat nyttjande av denna är därmed viktigt. Det leder dock till ett ökat behov av drift, underhåll och viss nybyggnation, samt till behovet av att se till dess miljöpåverkande faktorer. En miljöanpassad offentlig upphandling, således en hållbar upphandling av dessa entreprenader är ett steg närmare en hållbar utveckling. Syftet med miljökrav vid upphandling är att minska järnvägssektorns negativa miljö- och klimatpåverkan, och att främja miljöarbetets utveckling.

The purpose of this thesis is to identify the most important establishment criteria for companies whointend to do a new establishment. There are differences between regions regarding attraction on startup.Some regions have few new businesses while others continuously expanded its activities in variousfields. The biggest focus on the thesis is the Gävle- Borlänge region where MellansvenskaHandelskammaren is active.Mellansvenska Handelskammaren saw a need for the assignment after the magazine ?IntelligentLogistik? ranked the Gävle region at 15:th place and Falun/Borlänge at 20:th place in the list over thetop 25 best logistics locations in Sweden. This made them wonder what could be made to develop intoa better area with more amenities and a better place in the ranking of the magazine.

In recent years many cities have seen an increase in bicycle traffic. This is a development that benefits both the environment and the individual cyclist. When the need for bicycle parking is not met several problems arise such as an increase in bicycle thefts, jammed sidewalks and a decreased interest in using bicycles. My aim with this paper has been to answer the question of how to create parking facilities in an urban environment based on cyclists' needs. Through a literature survey, following the method "Trattmodellen" (the funnel model) the question has been answered and divided under the headings cyclist, bike, bicycle racks, bicycle garage and bicycle operators and hosts.

Utvecklingen inom järnvägssektorn går mot snabbare och mer effektiva transporter, dock begränsas utvecklingen av att det krävs nya och mer utvecklade spår och tåg för att uppnå det. Med dagens infrastruktur och tågmodeller är hastigheter på 200 km/h det maximala. Behovet att öka kapaciteten och införa höghastighetstrafik i Sverige utreds i nuläget. Med höghastighetstrafik avses hastigheter på minst 250 km/h. Banverket har som förvaltare av järnvägen ett sektorsansvar för miljön och således även buller.
