    Author : Joakim Axmon; Matematisk statistik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forestry; Silviculture; detection of decay.; Norway spruce; X-texture mode; signal subspace enhancement; partial forward-backward averaging; ESPRIT; state-space; Prony; frequency analysis; SIMO; impact response; Modal analysis; impact excitation; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Electrical engineering; Elektroteknik; Signal processing; Signalbehandling;

    Abstract : This doctoral dissertation concerns two-dimensional frequency estimation for modal analysis of single-input multiple-output impact responses from circularly cylindrical objects. The application is within detection of internal defects in trunks of spruce. READ MORE

  4. 2. Truck tyre rolling resistance : Experimental testing and constitutive modelling of tyres

    Author : Jukka Hyttinen; Lars Drugge; Jenny Jerrelind; James Busfield; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Truck tyre; PRF; filler reinforced rubber; ambient temperature; rubber testing; parametrisation; Finite-element simulation; Lastbildäck; PRF; gummi; förstärkande fyllmedel; effekt av omgivningstemperatur; gummiprovning; parametrisering; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Global warming sets a high demand to reduce the CO2 emissions of vehicles. In the European Union heavy-duty road transports account for 6 % of the total greenhouse gases and one of the main factors affecting these emissions is related to the rolling resistance of tyres. READ MORE

  5. 3. The Impact of Non-synchronous Generation on Power Systems Dynamics

    Author : Harold Chamorro; Mehrdad Ghandhari; Jonas Persson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Due to the increasing integration of Renewable Energy Sources (RES), and the installation of High Voltage Direct Current (HVDC) systems, more power is injected to the AC grid based on power electronic converters. This kind of power injection is called non-synchronous generation in this thesis. READ MORE

  6. 4. Modeling the mechanical performance of natural fiber composites

    Author : Erik Marklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : Due to environmental concerns the interest in use of renewable and recyclable materials has dramatically increased over the recent years. Wood and other lignocellulosic fiber reinforced polymers have large potential as structural materials due to the high specific stiffness, high specific strength and high aspect ratio of the fibers.
