  1. 21. The Influence of Customer Agreements and Planning Principles on Rail Freight Performance

    Författare :Lars Backåker; Lundgren Jan; Johanna Törnquist Krasemann; Stefan Engevall; Markus Bohlin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rail freight planning; trip plan generation; routing and scheduling; dynamic assignment;

    Sammanfattning : Rail freight transportation is recognized worldwide as a suitable transportation mode when it comes to long haul transportation of heavy commodities. The industry is also known to be capital intensive, highly dependent on infrastructural developments and requires thorough planning of operations. LÄS MER

  3. 22. At the crossroads of bioenergy and agriculture in developing countries : Challenges and prospects for fossil fuels replacement and CO2 abatement in the case of Thailand

    Författare :Wathanyu Amatayakul; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; bioenergy plantations; land-use decision; developing countries; CO2 abatement; ethanol program; Thailand; wood crops; CDM;

    Sammanfattning : Studies estimate that the potential contribution of biomass to the global primary energy supply from cultivation of crops for energy is substantial in the long term, from about 50 to 240 EJ/year in 2050. Most of this biomass is projected to come from cultivation in developing countries. LÄS MER

  4. 23. Reflective Spatial Haptic Interaction Design Approaching a Designerly Understanding of Spatial Haptics

    Författare :Jonas Forsslund; Eva-Lotta Sallnäs Pysander; Petra Sundström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : With a spatial haptic interface device and a suitable haptic rendering algorithm, users can explore and modify virtual geometries in three dimensions with the aid of their haptic (touch) sense. Designers of surgery simulators, anatomy exploration tools and applications that involve assembly of complex objects should consider employing this technology. LÄS MER

  5. 24. Intelligence Partitioning for IoT : Design Space Exploration for a Data Intensive IoT Node

    Författare :Irida Shallari; Mattias O'Nils; Muhammad Imran; Andreas Gerstlauer; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IoT; Internet of Everything; smart sensor nodes;

    Sammanfattning : The technological shift towards the Internet of Everything has resulted in an ever-increasing interest in smart sensor nodes. The required deployment of these nodes in a variety of environments, powered by constrained energy sources such as energy harvester or conventional batteries, is reflected in the significant constraints in terms of energy consumption for the smart sensor node.
