Masskattning av tunga fordon i realtid genom systemidentifiering
As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..
Datorsimulering av gruvlastare för funktionell testning
I denna rapport presenteras hur en simulatorlösning för funktionstestning av en gruvmaskin har tagits fram. Arbetet har skett i Atlas Copcos regi och består av tre delar: kartläggning i form av intervjuer, utvärdering av befintliga simulatoralternativ och slutligen val och implementation av lösning. Resultatet visar på en konceptuell prototyp, där en gruvmaskin visualiseras i en 3D-miljö tillsammans med en virtuell gruvgång. Detta möjliggör bland annat testning av autonom navigering, alltså att en gruvmaskin självständigt styr utifrån avläsning av tunnelväggar med hjälp av laser. Samtidigt tillåter lösningen också att kontrollvärden från olika sensorer, såsom vinkelgivare, kan hämtas ut ur simuleringen..
Lagerprogram för Satellitlager
Texo Application has created robots that they call for satellites; with these you can feed in storage pallets into a satellite storage. Satellite storages consist of channels in height (e.g.3 to 8 pieces) and width (e.g.3 to 100 pieces). Channels can be different long (e.g. 5 to 200 pallets). At deposit of a storage pallet the truck insert the satellite in a channel and then the pallet, the pallet is driven into the channel until it reaches another pallet or the other end.
Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China
Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.

Examensarbete G3 i företagsekonomi, 15 hp, Ekonomihögskolan vid Växjö universitet, Logistik, FE3583,VT 08.Författare: Stefan Knutsson, Linda Nilsdotter, Martin Svensson.Handledare: Helena ForslundFöretagets kontaktperson: Lars WoxnerydTitel: Södra - En studie om koldioxidutsläpp från externa transporterBakgrund: En mycket aktuell diskussion i dagens samhälle är klimathotet och människans negativa påverkan på miljön. De växande kraven på miljöarbete i företag gör att de ständigt måste utvecklas. Södra Timber har idag en uppskattad siffra på dryga 13 000 ton koldioxid som släpps ut vid distributionen av sågade trävaror. En siffra som i nuläget inte är helt tillförlitlig då schablonerna och beräkningarna är föråldrade.Syfte: Studien syftar till att kartlägga Södra Timbers koldioxidutsläpp vid kundtransporter genom att använda sig av en bättre beräkningsmetod som uppsatsen skall arbeta fram. Studien syftar också till att identifiera möjligheter till förändringar i distributionen med hänseende till koldioxidutsläpp och ekonomi.Avgränsningar: Uppsatsen är avgränsad till att endast behandla transporter som sker från sågverken i Långasjö och Mönsterås.Metod: Uppsatsen inleds med fördjupade teoretiska studier för att möjliggöra analys av det empiriska materialet.
Privatskogsägarens nettoinkomst vid avverkning under perioden 1952-2008
During the period 1952-2008, real prices of wood before taxes and charges declined. However, the actual net income has not changed by the same percentage as the price list, because taxation, driving costs and the ability to make deductions has changed. This report considers the inflation by using the Swedish consumer price index. Net income refers to the remaining income when relevant costs, taxes and fees have been paid.The purpose of this study was to examine how the private forest owner's real net income has evolved over the period 1952-2008 for three categories of forest owners. These three categories are1.
Den skogliga informationens roll i ett kundanpassat virkesflöde : en bakgrundsstudie samt simulering av inventeringsmetoders inverkan på noggrannhet i leveransprognoser till sågverk
This MSc thesis is divided into two parts. The first part deals with the need for information
from forest campartments selected for clear cutting, in connection with planning in an
integrated forest- and sawmill enterprise. A review of literature is followed by a case stud y,
where present conditions in a Swedish forest company are compared with current research in
the area. The seeond part consists of a simulation stud y, which aims at camparing the
accuracy of inventory estimates using different methods. The estimates are delivery forecasts,
covering one month consumptian of timber in a large sawmill.

Utvärdering av traktplanering på SCA Skog
This study is an analysis of a survey that harvester operators working for SCA Ångermanland Skogsförvaltning have been participating in. The purpose of this study is to try to show the harvester operators opinion about the forestry planning that SCA provides. Hopefully will this information lead to suggestion about what part of the forestry planning needs to be improved, if any is needed? Unfortunately only 30 / 60 questionnaire has been returned so no conclusion can be made, except about those who have answered the survey.
The answers of the survey indicate a number of areas that needs to be improved. The marked routes needs to be more visible and the education about timber landings must be enhanced.
