Utveckling av en dynamisk Simuleringsmodell av en skotare

The predominant forestry harvesting method is based on the harvester-forwarder method, theharvester folds, branches and cuts trees, and sorts the logs into piles, while a forwarder transportsthe logs to a landing area.This master thesis work is about realization of a dynamic forwarder simulation model, and itspurpose is to provide an integrated forwarder simulation model in MATLAB/SimMechanicswhere the forwarder is based on a concept using pendulum arms to connect wheels and chassis.Active suspension control is developed and implemented into the simulation model, and finallycompared in simulation with passive suspension.In a first step, an integrated forwarder simulation model is developed, containing a simplifiedforwarder model, a tire-to-ground interaction model and a test track model. The simplifiedforwarder model is based a rigid multi-body system with a spring-damper suspension of thependulum arms. The tire-to-ground interaction model calculates the reaction forces, friction fromthe ground and applies the propulsion force. The test track model is a simplified version of thereal test track in Skogforsk. The propulsion wheel torque control is used to regulate theforwarder speed.

Samband mellan virulensgener och VTEC-infektioner : Riskklassificeringssystem för VTEC

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.

Bergkyla och bergvärmeutredning för industrilokalen Rödbergsmyran 5 i Umeå, Västerbotten.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

Harry Martinson - en tidsresa i lyriken och dess förändringar

The aim of this study is to examine the significance of having a music department at the public library in Enköping, and how the organization of the phonograms is handled. The different areas examined are the reason of the reintroduction of a music department, its budget, its users, the work with selection, the marketing, statistical data concerning loans, the work with classification, indexing, and organization of the phonograms and the future of the music department. The empirical material consists of qualitative interviews with staff connected to the music department at the public library in Enköping. For the theoretical frame, Sanna Taljas discourse analysis of music libraries in Finland is used. Talja presents three discourses which all show different views on what kind of material a music library should contain.

Byggregler för brandskydd inom industrin: en jämförelse studie

I dagsläget finns tydligt regelverk som anger hur byggnader skall uppföras, dock saknas hjälpmedel för att kraven skall anses tillgodosedda på stora och komplexa byggnader som finns inom industrin, skall dimensioneras för att tillfredsställande brandskydd ska uppnås. Detta resulterar i att analytisk dimensionering (dimensionering baserad på uträkningar till skillnad mot förenklad dimensionering vilken i princip följer de allmänna råden) som regel måste användas även vid mindre byggnationer. Syftet med examensarbetet är att påvisa eventuella oklarheter i det existerande regelverket (Boverkets byggregler, BBR) 1 för brandskydd av industribyggnader i Sverige, där reglerna för förenklad dimensionering inte är anpassade för byggnader med industriell verksamhet. Målet är att om möjligt komma fram till hur man skall resonera vid dimensionering av brandskyddet i dessa byggnader utifrån en diskussion om rådande lagstiftning och de skillnader som påvisats mellan Sveriges och andra länders regelverk. Arbetet består av en litteraturstudie av de regelverk som finns för brandskydd i Sverige, där de avsnitt som är problematiska för industribyggnader lyfts fram.

Förnybar energi ur ett kvinnligt och manligt perspektiv : En attitydundersökning med avseende på att kartlägga hur synen på fönybar energi påverkas av om individen är kvinna eller man

Abstract The extraction and usage of energy give rise to immense environmental problems which helps to accelerate climate change. Energy is an important resource for the community and there are a variety of different types of energy sources available, that are either classified as renewable or non-renewable energy sources. The usage of renewable energy sources cause less environmental impact than the usage of non-renewable energy, which in turn means that the energy?s strain on the environment is strongly affected by the type of energy source used.The aim of the study is to describe to what extent attitudes towards renewable energy are affected by whether the individual is male or female, by examining the hypothesis regarding how women have a closer connection to nature and to a larger extent shows on an pro-environmentally friendly behavior than men, and if it also can be detected on issues related to renewable energy and thus imply that women have a friendlier approach towards renewable energy than men. A number of ecofeminist believe that women have a stronger bond with the nature through her embodiment as a woman and by her maternal role, which according to previous research also leads to the fact that women shows on a more extensive environmental behavior.Through a qualitative research method in the form of semi-structured interviews has three female and three male respondents been asked questions with regards to the environment, individual responsibility and energy.
