Since the end of the eighteenth century forest damage caused by the pathogen Gremmeniella abietina has been observed and documented. During the latest epidemic in Sweden more than 480 000 hectares forest land have been injured and this has lead to considerable economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these variables on the disease incidence. Further, the thinning performed during the time for spore dispersal and its relationship to injured stands is examined.

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room for a deeper investigation into editorial work within the framework of the thesis. Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production, printing and distribution. Production and discarding of media equipment was not taken into account.

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Artiklarna som kom fram är kvantitativa och Randomiserade Kontrollerade studier.Resultat: Resultatet av studierna visar att Bobathmetoden har positiv effekt för att klara aktiviteter i dagliga livet. Bobathmetoden visar förbättring från akuta fasen till efter behandling i ADL aktiviteter. Studierna visar att Motor Relearning Programme, Arm Basis training och Balance Performance Monitor träning har bättre effekt än Bobathmetoden i ADL aktiviteter.Arm Basis training, Motor Relearning Programme och Bobathmetoden förbättrade handfunktionen över tiden.

At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.

This essay takes the three models from Allison and Zelikow book Essence of decision and applies them on the Swedish defense system. After the cold war the Swedish defense system had to undergo changes to be a more modern defense and be able to defend Sweden against threats. To also be able to cooperate with other countries in peacekeeping operations the Swedish defense had to be reorganized. The solution was to change direction from a defense system that was organized for invasion to instead be a movable defense ready for any challenge in Sweden or abroad. This reorganization will be analyzed according to the three different models..

Mechanical scaling is one of the most complex operations of all in the mining process. The operators are using both hearing, sight and feel to read the rock and to know where to scale and where to leave. They say they go on gut feeling in great extent, something that comes with experience. The scaling machine is placed into the edge of unsecured and newly blasted rock to hammer off the blocks that has become loose after the blast, but not enough to fall down. It goes without sayingthat it is a risky job.

The study also aims to suggestwhat kind of service the library could provide accordingto the information needs and the most valued informationsources of the businesses..

Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.

Designsonder är en så kallad innovativ metod (Hanington, Methods in the Making: A Perspective on the State of Human Research in Design, 2003) som låter deltagarna i studien vara kreativa och delaktiga i designprocessen. Det finns ingen exakt definition av designsonder, men ofta handlar det om ett paket med ett antal uppgifter som delas ut till deltagarna. Exempel på vanliga övningar är att skriva en dagbok om användandet av artefakten som studeras samt att genom en engångskamera låta deltagaren dokumentera sitt användande.Denna rapport syftar till att undersöka designsonders potential som inspiration till designprocessen. Samtidigt undersöks hur metoden designsond fungerar på den aktuella målgruppen: studenter som använder Key-husets entrémiljö på Linköpings universitet. Rapporten belyser därmed problematiken med att ta steget från de tidiga faserna i designprocessen, där fokus ligger på att förstå användarna av artefakten som ska designas, till själva designandet av artefakten.

This study investigates communication and data in information systems. The paper deals, more specificly, with communication in a CRM-system implemented in a Swedish-founded company in Beijing, China. It discusses cultural, political, linguistic and gender based dilemmas that can arise from the use of a CRM-system in an international and bilingual environment. Fifty-nine interviews were conducted in Sweden and in China, either in Swedish or English. The result of this study shows that communication in the information system is affected by factors, that are not originated in technical shortcomings of the system, but rather from cultural, political, linguistic and gender based pre-knowledge among individuals.
