The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Climate change is the modern society?s common issue. The developed countries areconsuming more than what is sustainable, and the climate change due to the use offossil fuels can be seen clearly. EU has specified goals, in order to stop furtherdamage, which demand that every member state have to reduce its energyconsumption by 20 % before 2020 and 50 % before 2050, relative to 1995.The Swedish government uses a number of instruments to encourage reduction in theusage of energy, but every individual has to contribute to reach the goals.With increasing energy price the cost of living is going up. A lot of people are lookingfor ways to save energy and not be affected as much by the increasing price.Investments for insulation, replacement of windows and replacing old heating systemfor a new efficient heat pump is getting more and more common.This thesis is about investigating the possibilities in becoming independent from buyingenergy for households.

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 student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

How can former military area I5 in Östersund, Sweden, evolve into Stadsdel Norr ("The Northern Quarter") ? an attractive part of the town center? In a theoretical part of the essay the significants of well functioning towns and streets are investigated. The history of Östersund and I5 is shortly reviewed. Present recommendations concerning city design are presented along with guidelines from Vägverket (National Road Administration) for urban streets. The conclusion reached is that a fundamental structure of streets and roads, public and private spaces, is crucial for the possible future development of an area.

The world?s population reached more than 6.9 billion people in July 2011. It is expected that the population growth during the next 40 years will take place mostly in low-income countries and the population increase will be 2.3 billion people during 2011-2050. A rapid urbanization is also expected to result in 57.7 per cent of Africa?s population living in urban areas in 2050.

Trafiksimulering är ett användbart verktyg då olika typer av vägar ska studeras. Statens väg och transportforskningsinstitut, VTI, har under de senaste åren utvecklat en ny landsvägssimuleringsmodell, Rural Road Traffic Simulator (RuTSim) (Tapani 2005). För att en simuleringsmodell ska vara användbar måste den ge en god överrensstämmelse mot verkligheten. Syftet med detta examensarbete är därför att utvärdera RuTSim, genom att kalibrera och validera två 2+1-vägar och en vanlig landsväg med mötande trafik. Detta både för en implementerad frifordonsmodell samt befintlig modell med trafikinteraktioner.

Denna uppsats analyserar ?det fria? i en översättning ? alltså de kriterier som utmärker en fri översättning. Dessutom analyseras texttrogenheten utifrån ekvivalensbegreppet.I detta syfte ligger tyngdpunkten på en analys av semantiska tillägg ochutelämningar i måltexten. Dessutom studeras översättning av engelska namn, talspråk, svordomar och metaforer, samt ändring av syntaxen i måltexten. Materialetbestår av de två svenska översättningarna av Jack Kerouacs roman On the road, nämligen På drift från 1959 och På väg från 2008, som jämförs med originaltextenoch med varandra.

Sverige har som mål att år 2020 reducera energianvändningen för bostadssektorn med 20 procent och med 50 procent till år 2050. För att målen ska uppnås fordras fler energisnåla nybyggnationer och energieffektivisering på ombyggnationer.Av alla nybyggnationer som har produceras i Sverige är mindre än 1 procent energisnåla nybyggnationer. Studier visar att en av orsakerna till den låga marknadsutvecklingen för lågenergihus beror på att lågenergihus är generellt mellan 2 till 10 procent dyrare än traditionellt byggda hus. Andra orsaker är att många byggherrar inte känner till fördelarna att bygga energieffektivt. Det har även visat sig att byggherrar har för lite kunskaper om energieffektivisering och saknar förmågan att tänka långsiktigt vilket har bidragit att många byggherrar inriktar sig på kortsiktiga ekonomiska resultat istället för hela byggnadens livscykel.Syftet med den här rapporten var att beräkna merkostnaden och livscykelvinsten för nyproduktion av minienergihus och passivhus.

The purpose of this thesis is to investigate the democratization process in Kurdistan on the basis of consolidation democracy with focus on arenas defined by Linz and Stepan (1997), namely economic, political, legal, civil society and arenas of state bureaucracy. Furthermore, I intend to explain Kurdistan?s road toward democratization in Kurdistan from 1991 until today, with a focus on the years 2003-2012. The main results are that Kurdistan has developed conditions that support a future consolidation of democracy. However, there are weaknesses in the economic situation, rule of law and the arena of bureaucracy.

A lot of houses built during the Million Homes Programme are in need of major renovation. Today?s technology and materials are better than in the 60?s and 70?s. Both Swedish government and the European Union have set climate goals regarding energy consumption by 2020 and 2050. Achieving these goals would require better standards in buildings than the Building regulations demands, such as Umeå municipality?s construction requirements for new buildings.The report aims to investigate if a renovation of apartment buildings from the Million Homes Programme can reach Umeå municipality?s construction requirements.

The visions of the United Nations concerning sustainable development and conservation of biodiversity can only be realized if the human population succeeds in creating coexistence between human and wildlife. Landscape architects are able to influence on how landscapes are to be maintained and developed. The negative impact of infrastructure on wildlife has become a critical problem in Sweden and other parts of Europe. Wildlife crossings has been developed as a solution for the problems of road barriers in the landscape. The crossings are made to give animals a better opportunity to cross roads.

This paper examines which media messages related to happiness that can be found in interviews with famous people in the four largest lifestyle magazines in Sweden for the age group 16-34. The magazines are Cosmopolitan, Elle, Café and King. Depending on which magazine the reader chooses to read he/she will be presented with different roads to happiness. Common for all examined magazines are happiness factors related to personal goals, determination and work. Often in a causal connection where the goal orientation and determination is tied together with success in work and career for the interview persons.
