During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

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.

Lame dogs are a common group of patients for the practicing veterinarian. In the literature it is described how a clinical examination can be performed, based on general clinical-, orthopedic- and neurological examination, and visual evaluation of the dog when standing and during motion. For research, objective gait analysis systems are also used to study clinically healthy and lame dogs during motion. The aim of this degree project was to compare objective kinematic gait analysis with a visual evaluation of dogs with different types of lameness. The project was a pilot study to show if objective gait analysis could be used as a support for the visual examination. Ten lame dogs of different breeds and with different diagnoses were included in the study. They were all patients at the University Animal hospital, Uppsala.

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted. LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

This thesis has been made in cooperation with the forestry machinery producerEco-Log in Söderhamn. The focus of the thesis has been to find a cheaper wayto open the large engine hood of the company?s harvesters. The goal was tofind a solution that could increase the value for the customers by being saferand simpler to use, or, at the least, keep these values at an equal level comparedto the previous solution.In order to make it possible to CE-mark the new solution, it was importantMachinery Directive that came into effect from the beginning of 2010.To begin with, a specification of requirements was set up. Thereafter, anumber of different basic concepts was retrieved and evaluated.

Syftet med denna uppsats är att göra en undersökning om vilka faktorer som påverkar användares närvarokänsla första gången de använder sig av en inneslutande virtuell miljö. De inneslutande VR tekniker vi har valt att fokusera på är Computer Automatic Virtual Environment (Cave) och Head Mounted Display (HMD).Forskaren Carrie Heeter beskriver tre typer av närvaro och forskarna Wallace Sadowski och Kay Stanney räknar upp faktorer som de påstår påverkar användarens närvarokänsla.Vår frågeställning är vilka likheter eller skillnader det finns mellan våra testpersoners svar och Sadowski och Stanneys faktorer. Vi intervjuade och genomförde ett test med tre testpersoner i en Computer Automatic Virtual Environment baserat på två program. Vi valde även att intervjua två experter om vilka faktorer de ansåg påverkade deras närvarokänsla första gången de använde sig av en HMD.Första programmet som testpersonerna fick pröva på var Cuevadefuego som bestod av tredimensionella bilder till skillnad från det andra programmet, Crayoland, som bestod av tvådimensionella bilder. Intervjufrågorna till testpersonerna och experterna baserades på frågor som handlade om experternas och testpersonernas reaktioner och intryck relaterat till deras närvarokänsla och vad de trodde det var som påverkade deras närvarokänsla.Resultatet av intervjuerna och testet är att det finns likheter mellan de faktorer som testpersonerna anser påverkar deras närvarokänsla och med Sadowski och Stanneys faktorer men inga direkta skillnader..

Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinderwho grinds discarded plastics to granules which later can be reused when pressure molding plastics.The company wanted help in developing a new, or alternatively extending their previous,measurement equipment. The old equipment was hard to use, required changes in the code fordifferent measurement scenarios and had a limited array of measuring quantities. Rapid had an ideaof a similar concept only with a greater number of input ports, better range of applicable sensors andan advanced yet easy to use interface. The system is supposed to be placed at Rapid's test departmentwhere it will be used as a tool for finding faults and provide data which can be used for furtherdevelopment of the granulators.The project's members accepted the task and immediately began searching for suitable componentsfor the system. After the search was completed a list of costs, limitations, sensors, I/O's anddevelopment environment was presented to Rapid's staff.

Eco-design is all about improving products environmental performances throughout the products lifecycle by including the environmental aspect into the product development process. There are a large number of different tools that can be used for this, but there are several factors that can affect which one will be the best to use. Some tools for eco-design takes comprehensive studies and can only be performed by experts, while some tools can be used more time- and cost efficient and with basic knowledge. The choice of tool should be based on the company?s situation.This report describes the research of how the design and furniture company Blå Station could include a tool for eco-design in their product development process.

This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.

A field experiment was carried out in 2006 to investigate the effects of deep rotary cultivation on sugarbeet growth. The background to the experiment was a 2005 study showing potentially higher yield, higher cleanness and higher sugar content when primary tillage was carried out to 35 cm depth with a rotary cultivator. On four field sites in Skåne (L:a Isie, Ädelholm, Stävie and Vragerup), five different treatments were compared: mouldboard ploughing in the autumn to 20 cm; mouldboard ploughing in the autumn to 20 cm + rotary cultivation in the spring to 35 cm; rotary cultivation in the autumn to 35 cm; rotary cultivation in the spring to 35 cm; and mouldboard ploughing in the spring to 20 cm. The rotary cultivator used in the treatments is manufactured by a Dutch company, Imants. The implement cultivates the soil with spade tines fitted on arms that are mounted on a horizontal rotating PTO-driven axle. Beet plants were inspected and yield determined in the experiment, and three soil parameters were examined: penetration resistance, water infiltration and infiltration of blue dye. Root shape was also examined. The site at Stävie was not harvested due to poor beet establishment. At the other sites, the highest yield was found when the soil was rotary-cultivated in the autumn.
