Scania provides a fleet management system for hauliers who want to control their fleets in anefficient way. The system includes an onboard computer with touch screen called ScaniaInteractor where the driver can access GPS navigation, order support, message service and otherfunctionalities. The purpose of this thesis is to develop a concept for Logging the user interactionon the Interactor and analyze the result which enables further development and optimization ofthe interface.A demonstration application is designed, implemented and tested for the purpose of showing thepossibilities and difficulties with Logging of interaction. The result shows that Logging is quiteeasy to implement and that the amount of produced data is small and therefore not expensive totransfer via GPRS to a central server where searching and analysis can be done. On the otherhand, the biggest challenge lies in the analysis and interpretation of the logged data and to applyit to the development of the interface.

Biofuels are getting more important as EU plans to replace fossil fuels with renewable energy sources. Because of that Sveaskog has chosen to invest in developing the handling process of Logging residue. The company has a joined organisation for handling both round wood and Logging residue. They are also working at integrating the forwarding of the Logging residue with the rest of the harvesting team. Sveaskog is currently extracting 44 % of the available amount of Logging residue.

The aim of this study was to investigate how seasonal variations affect the quality of Logging residues. The study was hosted by VIDA Energy. Logging residues can be processed and transported within different systems. Today the dominant systems are chipping at landing and bulk transportation of Logging residues. In these systems the handling of the Logging residues are carried out in the same manner up to the landings. Moisture content at the time of chipping is the primary quality parameter. Fine fractions of Logging residues are strongly dependent on moisture content in storage.

During some time there has been a debate whether or not Logging contractors? profitability can be considered poor. The contractors? situation is important for maintaining long term relationships and continuity in the forest industry. A thorough analytic picture is however missing.

The Department of Forest Products and Management, Swedish University of Agricultural Sciences has received means from Vinnova for a preliminary study of the organisation of Logging work of today and how a better Logging organisation should be brought about. This thesis reports results from qualitative interviews with nine forest machine contractors regarding the situation of their companies. The interviews have been analysed with respect to the genesis of the companies, which tasks they perform or that they could consider perform-ing, business relationships of the companies, relationships between the different partners of the companies, and the state of competition experienced by the contractors. The companies have developed either from the contractor previously being machine operator employee or from that the contractor in making has owned a machine and needed work. Their primary business is mechanised Logging.

This study has analyzed particel size distribution and needle content in chipped Logging residuals (branches and tops) delivered to the district heating plant Ryaverket in city of Borås, Sweden. Two fuel assortments has been analyzed: Chipped Logging residuals from pure softwood and from mixed fuel (connifers and broadleaves). The samples has been sieved at Linneaus University laboratory.The study of particle sizes indicates that only 53,2 % of delivered fuel is within the fuels specification (7? 45 mm). The needle content is in this study 12,4 % (dry mass) which is higher than expected..

This study was carried out at the request of the bio energy company Naturbränsle. The company handles annually 750 000 m3 of chips from Logging residues from a large area, from Östergötland in the south to Härjedalen in the north. In that area, about 50 bio fuel plants are customers. When Naturbränsle deliver chips from Logging residues to their customers, the moisture content varies from 30 % to 60 %. The aim of the study was to sort out the affecting factors on the moisture content in the chips during handling and storage processes.

This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about Logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards Logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of Logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep Logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

This piece of work develops a solution that automates protection against software keystroke loggers. Keystroke loggers can be used illegally to register a user's keystrokes and in that way acquire sensitive information. The solution was tested on two different networks and the efficiency was measured. The network represents an enterprise network that uses the operating system Windows along with the directory service Active Directory. A script was developed to solve the automation matter.

Fuel wood is currently the third largest assortment from the forest in Sweden after pulpwood and lumber. Branches and tops i.e. Logging residues are one of the assortments of fuel wood which is a common by-product after harvesting nowadays. The way to utilize, disintegrate and transport the Logging residues varies between northern and southern Sweden. Branches and tops are collected throughout the year at appropriate stands, but are consumed mainly wintertime.

The market for biofuels from the forests have had a positive development and the job initiators for this master´s thesis wanted to examine the profitability of a method for harvesting forest fuel, which was unfamiliar to them. The method was the ?long tree tops-method?, here called the LT-method. The LT-method is characterised by the fact that timber is harvested as the only roundwood assortment while the rest of the stem, which in other cases would become pulpwood, is harvested as forest fuel together with the Logging residues. The method is based on the assumption that advantages in handling of the forest fuel assortment such as increased load weights for forest hauling and truck transportation, should compensate for the lower price for pulpwood when sold as forest fuel. The aim of the study was to compare the profitability of the LT-method with the GROT-method (harvest of timber, pulpwood and Logging residues) and conventional Logging without any harvest of forest fuel, and aslo to try to identify factors affecting the profitability of the different methods.

The costs of Logging and of transportation with truck are dominating the total cost of wood delivered at industry. To support the profitability for the members' forestry the processing and handling with the timber has to be as efficient as possible. Increased length of pulpwood in thinning is one conduct that can result in higher productivity and/or lower costs. The study is scaled as a system analysis with the aim to exemplify the differences between working with 3- and 4-meter as standard length of pulpwood, related to biological aspects, timber receipts, cost of Logging and cost of transportation with truck. Important aspects are if the change is technically and biologically feasible and economically profitable.

The E-department at GETRAG All Wheel Drive in Köping have problems with the efficiency on parts of their production equipment. The equipment with the most significant efficiency problems are four automated multifunctional production cells that produces housing for rear drive units. The major part of the problem is the large amount of small stops that causes the low efficiency.The department already worked with Logging of interruptions and efficiency calculations before this project started. However this work was not done to the extent considered necessary for a systematic follow-up of the interruptions.The aim of this paper is to point out a more effective and systematic way to work with Logging of interruptions and the follow-up. In addition the equipment were studied with a method for efficiency calculation that ? if used properly- is a more powerful and a visually better method than the one used by the company today.As the initial current state analysis of the equipment was made a lack of documented knowledge about the equipment was discovered.
