   Sammanfattning : The increasing concerns for safety and environmental sustainability create demands on the development of future maritime transportation strategies. One way to meet these demands is the concept of autonomous unmanned vessels for intercontinental voyages. LÄS MER

5. 24. Simulator-Based Design : Methodology and vehicle display application

   Författare :Torbjörn Alm; Kjell Ohlsson; Martin Helander; Peter Hancock; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulator-Based Design SBD ; Human-in-the-loop simulators; Virtual prototyping; In-vehicle systems; Human-machine interaction HMI ; 3D situation displays; Adaptive interfaces; Work sciences and ergonomics; Arbetsvetenskap och ergonomi;

   Sammanfattning : Human-in-the-loop simulators have long been used in the research community as well as in industry. The aviation field has been the pioneers in the use of simulators for design purposes. In contrast, corresponding activities in the automotive area have been less widespread. LÄS MER

7. 25. Forestry machine and soil interaction for sustainable forestry

   Författare :Abdurasul Pirnazarov; Ulf Sellgren; Kjell Andersson; Sally Shoop; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CTL-logging; forestry machine; forwarder; multi-body simulations; roots; terramechanics; wheel-soil interaction; WES model; Machine Design; Maskinkonstruktion;

   Sammanfattning : More than 50 percent of the land area of the Nordic countries Finland, Norway, and Sweden are covered by dense forests and they are among the most important producers of forest products in the world. Forestry in these countries is based on sustainable management principles – reforestation follows harvesting. LÄS MER
