Today's communication solution between the vehicle and trailer is one many see as anon-viable solution, then breakdowns on both the lights and cables are common. Now, anew innovation enters the market, a system that can transmit wireless control signalsbetween the vehicle and trailer.Parvus and Zap, the two solutions that the projekt group has come up with during thisthesis work carried out over the last year on Utvecklingsingenjörsprogrammet.Technologists Peter Jägevall and Christopher Åberg has developed this project on theirown. The group has developed various concepts and chosen to work on, two of them.The project has resulted in this report and a prototypeThe solution that the group has developed is a wireless communication between vehicleand trailer. The project team has developed new power-efficient LED lighting fixtures inorder to implement an internal power source in the trailer. The result of this has becomea maintenance-free and wireless product to trailers.

This Master of Science thesis project handles issues around managing data from the digital tachographsystem. European legislation states that companies must download the data of the digital tachograph systemand store it for at least one year for control purposes. The system stores data on the vehicle unit located inthe driving compartment and on smart cards personal for each driver.Acquiring data from the previous analogue tachograph was done instantaneously since the data wasphysically printed to a circular paper chart when driving. To acquire data from the digital system one mustperform a download from the vehicle unit and later transfer it to some form of backup solution for longterm storage. Data must also be downloaded from the driver smart cards.Download of data from the vehicle unit is the most time consuming task and may take up to 30minutes pervehicle.

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Over the past few years the Åland islands have attracted growing internationalattention as an example of how to successfully secure the position of a minorityregion, and in the current situation the government of Åland has an intention toextend the efforts of spreading the example of Åland. The purpose of this essay isto shed light on the political discussion about the example of Åland, andinvestigate the underlying political reasons for emphasizing the example of Ålandinternationally. Through interviews with leading politicians on Åland I analyzeÅland as a norm entrepreneur. The research shows that besides altruism, selfinterestis a factor behind emphasizing the example of Åland. The essay showsthat the theory of norm entrepreneurship also can be applied on an autonomousarea, but instead of influencing international organizations themselves, theautonomous area use norm entrepreneurship as a tool for influencing domesticpolitics..

This essay is a philosophical investigation of the relation between children and their play. My aim is to see if children are autonomous when it comes to their play. Is there a moral boundary between those who take part in the play and those who do not? This topic is especially important when it comes to the moral status of a child in the Swedish pre-school. How should educationists act when it comes to children?s play?  Through an analysis of the notions of play and autonomy I show that play can be understood as something of a moral value to the child and if children should be seen as autonomous when it comes to their play.

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

Bakgrunden till studien är att forskningen visar att elever i svårigheter utvecklas mest kunskapsmässigt och mår bäst socialt av att inkluderas i klassens undervisning. Trots detta finns det väldigt ofta en önskan att exkludera dessa elever eftersom många lärare inte anser sig klara elever med specialpedagogiska behov inom den ordinarie undervisningens ram. Detta har lett till en rättvise- och inkluderingsdebatt såväl som en debatt med ekonomiska förtecken. Frågor som lyfts är ?Var mår eleverna bäst och finns det metoder som fungerar så att alla elever kan inkluderas?? Min studie syftar till att undersöka möjligheten till ett inkluderande arbetssätt i engelskundervisningen med hjälp av Europeisk Språk Portfolio och Autonomous Learning.

At the plant of Sandvik do Brasil in São Paulo there is a need for improving the transport of inserts between the plant building and the stock building. The idea is to install a system with an Automated Guided Vehicle (AGV) to take care of this transportation. The purpose of this report is to present which demands there are on the system and to find the best solution according to the demands.To conclude this work a study was made of the plant and the AGV technology was examined. Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load vehicle using inductive wire as guiding system..

This report is an assessment of the feasibility of using aerial photographs to estimate number of stems per hectare in young forest stands, used together with upper height to determine the need for pre-commercial thinning or ordinary thinning cutting. Aerial photo-interpretation was conducted in 2007 on assignment of Stora Enso Skog AB. A mean height function based on stand age produced with data from Bergvik Skog AB?s 2006 forest inventory assessment was used as a proxy for upper height and used together with photo-interpreted number of stems per hectare to determine the need for thinning cutting according to Bergvik Skog AB?s definitions. The test area is located north of Falun on Bergvik Skog AB?s land.Flight altitude was approximately 900 m above ground and the aerial photos were taken by L&L Flygbildteknik AB.

The subject of this bachelors degree project is an interior layout for road ambulances.Landstinget Västernorrland (LVN) wanted a layout concept that would be used to com- municate their design intentions to the ambulance producers during their purchase process.Designing ambulance interiors is an extremely complex process since there so many fac- tors to take into consideration. It ?s not just about taking the equipment and place it where there is space left in the cabin. You have to start with the user in focus and the tasks that are to be performed in the ambulance environment.It ishard to find design solutions that will fit 100% of the ambulance personnel?s working routines for 100% of the tasks.

Good comfort for the driver of a construction machine is crucial. Gearshift comfort is an important part of the total comfort. Volvo Construction Equipment Components has a simulation environment of the powertrain, SimPow, which is implemented in Matlab/Simulink. SimPow is mostly used for simulation of control strategies and performance. In order to be able to study gearshifting comfort, Volvo has an interest in developing new models for SimPow.

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

When farm animals are transported there are several factors that can affect their welfare. If the vehicle has an accident the welfare of the animals transported will probably be compromised. The aim of this study was to make a survey of accidents with animal transportation vehicles in Sweden. The survey included the number of accidents from January 2000 to May 2014, the cause of the accidents and how the animal welfare was affected by the accident. The authorities which were likely to have reports about accidents involving animal transports were contacted. There were no collected records about transportation accidents and the authorities referred to eachother for information.

When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.
