  2. 1. Green Logistics through Modal Shift - exploring the role of the transport capacity contract

    Author : Fredrik Eng Larsson; Teknisk logistik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green logistics; modal shift; mode choice; capacity management; supply chain contracting; intermodal transport;

    Abstract : Among policy-makers in Europe the modal shift - a shift från polluting modes of freight transport to less polluting modes - has been a popular suggestion for reducing CO2-emissions of transportation. In particular, intermodal road-rail solutions, where a combination of road and rail transport is utilized to move trailers and containers, have been stressed as an important measure to reach de desired reduction in emissions.

  4. 2. Continuously Variable Split-Power Transmissions with Several Modes

    Author : Per Mattsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuously variable transmission; variator; speed ratio range; ratio coverage; traction drive; mode shift; CVT; planetary gear; power split; IVT; infinitely variable transmission; epicyclic gear train; hydrostatic variator;

    Abstract : A continuously variable transmission (CVT) of split-power design consists of a variator and an arrangement of planetary gears. A black box model describing such transmissions is presented. The model can be used for synthesis as well as loss-free analysis of split-power CVT concepts in general. READ MORE

  6. 4. Robust Visual Object Tracking mean shift, particle filters and point features

    Author : Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PF; MSEPF; mean shift; visual object tracking; RANSAC; SIFT; SURF;

    Abstract : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state ofthe object and how it changes over time, in recursive video frames. READ MORE

  7. 5. Cost-effective maintenance of railway track geometry : a shift from safety limits to maintenance limits

    Author : Iman Arasteh Khouy; Peter Veit; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : Railway infrastructure is a complex system which comprises different subsystems. Long life span is one of the important aspects of this prime mode of transport. However, the useful life of its assets is highly dependent on the maintenance and renewal strategy used during the assets’ life cycle. READ MORE
