  2. 1. Suspended forestry machines for sustainable forestry

    Author : Abbos Ismoilov; Ulf Sellgren; Kjell Andersson; Viktor Berbyuk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Abstract : Cut-to-length (CTL) logging is a mechanized two-machine solution. The harvester processes treestems into smaller logs and a forwarder transports the logs from the logging site to a landing areaaccessible by trucks. READ MORE

  4. 2. Evaluation, Transformation, and Extraction of Driving Cycles and Vehicle Operations

    Author : Peter Nyberg; Lars Nielsen; Erik Frisk; Jonas Fredriksson; Linköpings universitet; []
    Keywords : ;

    Abstract : A driving cycle is a representation of how vehicles are driven and  is usually represented by a set of data points of vehicle speed  versus time.  Driving cycles have been used to evaluate vehicles for  a long time. READ MORE

  5. 3. Measurement-Based Modeling of Wireless Propagation Channels - MIMO and UWB

    Author : Johan Kåredal; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; personal area networks; MIMO; channel modeling; Propagation; channel measurements; vehicle-to-vehicle communicationa; ultra-wideband;

    Abstract : Future wireless systems envision higher speeds and more reliable services but at the same time face challenges in terms of bandwidth being a limited resource. Two promising techniques that can provide an increased throughput without requiring additional bandwidth allocation are multiple-input multiple-output (MIMO) systems and ultra-wideband (UWB) systems.

  6. 4. Perspectives of Aerodynamic Drag and Cooling Airflow for Heavy-Duty Trucks - Reconsidering European Total Length Legislation

    Author : Helena Martini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooling airflow; CFD; under-hood design; soft nose; truck-trailer combinations; inlet duct; outlet duct; aerodynamic drag;

    Abstract : Increasing fuel prices and constantly lowered emission legislation forces the vehicle industry to develop new methods for propelling vehicles and to optimize existing technology. Trucks constitute a significant proportion of the transportation system; consequently it is of great importance to ensure as low an impact as possible on the environment. READ MORE

  7. 5. Evaluation, Generation, and Transformation of Driving Cycles

    Author : Peter Nyberg; Lars Nielsen; Erik Frisk; Richard Stobart; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Driving cycles are important components for evaluation and design of vehicles. They determine the focus of vehicle manufacturers, and indirectly they affect the environmental impact of vehicles since the vehicle control system is usually tuned to one or several driving cycles.
