This report is part of the major thesis carried out at Stoneridge Electronics in Bromma,Stockholm during autumn and winter 2005-2006. The background to the thesis is the trendwithin the automotive industry where color displays have become more common for presentationof information to the driver, a trend that has come to the commercial vehicle market. Thepurpose of the thesis has been to evaluate whether programmable logic, with respect to FPGAtechnology, could be suitable for display control and graphics generation of these more complexcolor displays in automotive environment.Within the scope of the thesis the FPGA technology has been investigated, i.e. whatopportunities and threats there are with aspect to environmental and security requirements. Inaddition, the market of FPGAs and pre-built IP-cores has been investigated.

In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration?s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied.

Deferred shading är en renderingsteknik som har blivit allt mer populär i och med att hårdvaraukraven för tekniken inte längre är ett hinder. Ett problem med deferred shading är fortfarande hur transparenta objekt ska hanteras. Rapporten utvärderar två olika deferred pipelines som hanterar transparent geometri på olika sätt, de två renderingsmetoderna är Inferred Lighting samt Light Pre Pass med framåtrendering för hantering av transparent geometri..

Nya typer av krigföring, så som COIN-operationer (Counter insurgency), ställer nya krav på flygstridskrafterna. Utvecklingen av det bemannade stridsflyget har, om man jämför med UAV (Unmanned Aerial Vehicle), trots detta stått relativt stilla. Obemannat stridsflyg har samtidigt utvecklat förmågor som gör funktionen till en värdig konkurrent på det moderna slagfältet. Syftet med denna uppsats är att undersöka huruvida obemannat stridsflyg kan överta det bemannade stridsflygets plats inom ramen för COIN-operationer. Detta avser jag uppnå genom att undersöka hur väl de båda funktionerna svarar uppmot de krav som ställs på ett stridsflygplan i en operation med inslag av COIN.

In this study a case study was conducted at the Transport Agency. The government agency is seeking better alternatives to its current ways of keeping track of important dates stated in legal documents. The agency wants to explore the possibility for an IT-solution for keeping track on those dates. In the case study change analysis was conducted on the vehicle type approval process. Qualitative interviews were conducted with a section manager, vehicle type and component approvers, and with a system administrator and a system manager at the Transport Agency in Borlänge.

This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.

High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

The main purpose with the BVS10 is to enable transportation of material and personnel thru tough terrain.

My bachelor?s dissertation concerns the creation of a proposal for interior decoration of the Boland High School?s canteen. I have been in contact with personnel, students and the school principal through the duration of the project. In the end, substantive changes of lighting, interior decoration and movement were proposed for the canteen. In the proposal I have focused on accentuating the school?s profile, on creating smaller spatial configurations within the larger configuration of the room, lowering the noise level, creating a good movement flow, increase the number of seats and creating a pleasant environment in which to eat..

This is a thesis presents a differential gear which is found in a tracked vehicle called BvS10. The tracked vehicle is manufactured by BAE Systems Hägglunds AB in Örnsköldsvik, Sweden. The differential gear has a bolted house. The differential meets the requirement specifications, but the problem is that the bolts are sheared off because of the extreme torque that the differential is exposed to resist.Previous report on the differential show pictures of bolts which have been sheared off at the threads. This report is also includes three lists that explain seven different proposals which some are approved and some are not, and the report also presents the force, tensile, and shear stress.In a bolted connection there is both axial tension stress and radial shear stress, which can lead to wear out and broken bolts.
