The world we live in becomes more globalized as a result of new communication media. Communication occurs over greater distances which leads to increased travel. In the report AR5, by IPCC, it is showed that the human impact of climate change is clear and that something has to be done. Therefore its very important to change the human impact. A part of it is to change the way we travel within the service which leads to the purpose of the thesis.

The fork lifter chipper truck is a concept which has been developed for harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.

One of the most distinguishing features for companies today is that they must have a close collaboration and keep up a good relationship with their suppliers. This is important for the companies chance of survival and for them to compete in their markets. This essay will discuss the subject of Scania?s long-term collaboration with their suppliers. The purpose of the essay in this case study is to analyze if a long-term cooperation with a supplier is of essence upon renegotiations of continued collaboration.

This Masters thesis is made as the first of two visitor surveys of three urban forest areas. These areas are; Skutan recreational area in Haninge, Ugglevikskällan on Norra Djurgården in Stockholm and the Paradiset Reserve in Huddinge. The study is made in cooperation with the managers of the three areas operating within the European Union Life Project regarding Urban Woods for People. The goal has been to collect data through studies of visitors and close by residents in the three areas. The results are to be used as primary values for the follow-up as well as a basis for managerial decisions. The interviews and surveys are also constructed in a fashion so that they can be used for the follow-up study. For the Skutan recreational area the mode of contact was by sending forms to the nearby residential areas.

Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.

The main aim in this Master thesis is to analyse how an ideological view may have influenced the shape of hierarchies with a specific concentration on the concept of fiction genre in the latest versions of the systems SAB and DDC. Our thesis is that no theoretical classification scheme can be recognized as objective. With an ideological/institutional perspective we look at the structures behind these systems. As a vehicle we use the hermeneutic circle to show the play between part and unit by focusing and analysing three different levels: the content level the concept level the ideological level. The first level is in the shape of a historical background and an analysis of concept with focus on content.

Syftet med denna uppsats är att jämföra/analysera förmågorna till Suppression of Enemy Air Defences (SEAD) hosJAS 39 och en svensk UCAV år 2015. Årtalet 2015 är valt för att flera bedömare anser att det är först vid dennatidpunkt som en Unmanned Combat Air Vehicle (UCAV) har en utvecklingsnivå som tillåter att de sätts in i SEADuppdrag.I uppsatsen redovisas vilka krav som ställs på en plattforms sensorer och bekämpningsförmåga för attgenomföra ett SEAD-uppdrag mot två utvalda typer av mål. Därefter sker en jämförelse mellan de båda farkosternasförmåga att detektera respektive bekämpa de båda målen. Resultatet visar att JAS 39 som bemannad plattform har enfördel i de fall då operationer är hårt styrda av Rules of Engagement (ROE), särskilt gäller detta vid fredsbevarandeoperationer. Uppsatsen visar även att flygplanradarns förmåga att upptäcka och identifiera markmål är beroende avinförandet av en SAR-mod.

The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.

Det finns två stationer på Boxholm Stål AB med produktionssågar. Den ena är en bandsåg och två fasmaskiner med hanteringsutrustning för transport mellan såg och fasar samt en automatisk buntmaskin. Fasarna på den stationen är utslitna och håller inte de toleranser som Boxholm Stål AB har på sina produkter. En önskan att kunna planfräsa ändarna har också tillkommit vilket utrustningen i dagsläget inte klarar av. Det innebär att fasarna ska bytas ut.

Som ett resultat av attackerna mot USA den 11 september 2001 förklarade dåvarande president George W Bush krig mot terrorismen den 20 september samma år. Sex dagar senare undertecknade Bush ett direktiv vilket auktoriserade den civila amerikanska underrättelsetjänsten Central Intelligence Agency att utföra riktat dödande mot fördefinierade individer i syftet att förhindra nya attacker från terroristnätverket Al Qaeda, talibanerna och associerade styrkor. Bush initierade det amerikanska bruket av så kallade ?drone strikes? i anslutning till krigsförklaringen med intentionen att eliminera misstänkta terrorister utan möjlighet till en rättvis rättegång, Obama-administrationen har valt att fortsätta utöva policyn. Syftet med studien är att fastställa huruvida USA:s juridiska rättfärdigande och bruk av folkrätt i relation till genomförandet av riktat dödande och användandet av obemannade luftfarkoster i kriget mot terrorismen kan betraktas vara förenligt med doktrinen för just war theory och gällande internationell rätt.

When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.

Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling. The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.

During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.

Ökande behov av vård i dagens samhälle kräver ett väl utvecklat transportsystem för eneffektiv vård. För att en god vård räcker det inte bara utveckla vår hälsovård, utan det måsteockså utveckla transportsystem och materialflöde inom sjukhuset. Undersökningsobjektet avdenna studie är transportsystem i Södersjukhuset, där i nuläget all transport sker ikorridorerna via förarstyrda truckar.Korridorer är de mest besökta rummen i sjukhusen. Det är således viktigt att se till att ha entrygg och trivsam miljö i korridorerna. Därför krävs det tillsyn till en hel del normer ochbestämmelser som framförallt boverket ställer på dessa byggnader.I detta arbete har kulvertarna (korridorerna) på Södersjukhuset undersökts.
