Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

Introduction: The concept of CSR was first coined in the 1950?s and refers to corporate vol-untary work to contribute to a sustainable society. In Sweden, companies within the finance sector are among the worst when it comes to implementing CSR in their daily work. The debate on whether companies should engage in CSR activities or not, is extremely relevant nowadays. Right now we are facing a time where the demand on companies to take their social responsi-bility becomes more intensified.

the most obvious problem at Traction today is the in-between handling that demands much time and resources. The reason is that the packages are not designed with handling in mind. Several of the packages of today also have a poor degree of utilization that means there is room for a fewer number of articles. That in turn means more packages, more transports, more storage space and more staff. On the basis of a specification of demands ? which take quality and environmental influence, as well as transport, handling and economy in account ? we have developed suggestions on new packages that will facilitate handling and lower the total costs, The time of handling will in some cases abbreviate to just a few seconds with the new packages.

Detta examensarbete har utförts hos Liko AB i Alvik, Luleå. De säljer främst personlyftar för rörelsehindrade människor, och deras kunder finns i Sverige och i ett 20-tal länder till. Logistikavdelningen på Liko AB har insett att transporter från dem till deras kunder är en viktig del i deras arbete. I dagsläget anlitar de till största del Schenker AB för transport och de har liten insyn i, och dålig kunskap om, den delen. Syftet med detta arbete är att kartlägga hur transport från Liko AB till kund fungerar i dagsläget.

ABSTRACT Introduction: During the past 40 years the ambulance service in Sweden has evolved from mainly being a source of transport to today?s high-tech caring facilities that enable qualified care to start already in the patient?s home. This first level of care is now provided by registered nurses and registered nurses with specialist training in pre hospital care.At the same time as the care provided is becoming more advanced, results from studies demonstrate that the amount of dispatches to patients that lack the need for ambulance care and transport is increasing. Nurses in pre-hospital care possess the knowledge, training and authority to perform an initial assessment of patients and also treat patients according to local and national guidelines. After the treatment it would sometimes be possible for the patients to remain at home without having to use ambulance transport to an emergency department or in other cases find other means of transport to hospital.

Detta arbete kom till på inrådan från Jordbruksverket som tagit emot telefonsamtal från hästägare som haft problem med att få titta till sina hästar i samband med färjetransporter. Regelverket kring transport av djur är omfattande och detaljerat och man måste ta hänsyn till både den nationella djurskyddslagstiftningen och EU:s regelverk, Rådets förordning (EG 1/2005). Jordbruksverket var främst intresserade av efterlevnaden vad gäller de regler som hanterar tillsyn av hästarna samt ventilation och placering/fixering av transporten på färjan. Enligt transportföreskrifterna (DFS 2006:9) ska transporten placeras nära ett friskluftsintag och hästarnas tillstånd ska kontrolleras varannan timme under färjeöverfarten. Det är länsstyrelsens djurskyddskontrollanter som har i uppdrag att kontrollera lagens efterlevnad, både på land och till sjöss.Transport av djur ökar risken för lidanden såsom hunger, törst, obehag, smärta, frustration rädsla och oro.

SAMMANFATTNINGEnergianvändning under produktion av nya byggnader är en aspekt på den angelägna miljöfrågan, men än saknas både regleringar och undersökningar. I denna studie görs en jämförelse av energianvändning och utsläpp vid byggnation och transport av byggmaterial för två nybyggda hus ägda av Gavlegårdarna AB på Sjåaregatan 19 och Maskinistgatan 19: Gävle. Strand Etapp 2 kallas projektet på Sjåaregatan 19 och Maskinisten kallas projektet på Maskinistgatan 19 i denna undersökning. Målet för studien har varit att fastställa vilket av dessa två projekt som har haft lägst energianvändning samt utsläpp av växthusgaser vid resningstillfället, dvs. under projektens produktionsskeden.

Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.

Behovet inom FM att transportera militära förband i fredstid inför en övning eller vid mobilisering, har alltid varit stort inom Sverige. I och med att FM ominriktades så uppstod bl.a. förändringar av förbandstyper. Detta i kombination med den tekniska utvecklingen på civil och militär sida, kommer troligen att medföra både problem och möjligheter vid transport av militära förband i framtiden. Uppsatsens syfte är att analysera vilka möjligheter FM kan komma att ställas inför, avseende utnyttjande av civil och militär transportutrustning i framtiden.

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

Purpose: This study aims to examine the price transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.

I detta examensarbete undersöks vad som lockar med bilen som vardagligt transportmedel hos invånare i Malmö. Som en del i detta, identifieras faktorer bakom valet av transportmedel. Malmöbors tankar kring sin egen miljöpåverkan samt vilka utmaningar vi står inför när det gäller att gå emot ett mindre bil-dominerat samhälle diskuteras. Metoden bestod i att genomföra samtalsintervjuer med sex personer som samtliga bor i Malmö och som har körkort och tillgång till bil. Resultaten tyder på att bilens attraktion består i de fördelar den tillhandahåller, såsom lastutrymme, sparad tid, frihetskänsla och oberoende.

Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

We travel more nowadays. The increasing travel rate generates greenhouse gases which in the long run cause an increasing number of natural disasters over the world. Car traffic is a major contributor to this development. Out-of-town shopping centres have historically good accessibility for car traffic. This study aims to look into what are the factors that influence the choice of transport mode for dwellers in the outskirts of a town when going to out-of-town shopping centres.
