  1. 11. Learning Physics Through Communication During Laboratory Work : An empirical study at upper secondary school

    Författare :Jan Andersson; Margareta Enghag; Carl Angell; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Physics education; Laboratory Work; Inquiry; Communication; Discourse Analysis; Physics; Fysik;

    Sammanfattning : Laboratory work as a teaching and learning method is given prominence in the Swedish physics curriculum for upper secondary school. It is emphasised that students should be given opportunities to develop the ability to search for answers to questions, plan, conduct, interpret and present results. LÄS MER

  3. 12. Improving energy use in sawmills : from drying kilns to national impact

    Författare :Jan-Olof Andersson; Micael Öhman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Increased concern about environmental problems has amplified the public`s interest inenergy usage. The improved subsidies for biomass, together with the rising energy priceshave made biomass a desirable product on the energy market. LÄS MER

  7. 15. Route Adaptation of Charge strategies for Hybrid Vehicles

    Författare :Jan Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver model; modelling; control strategies; road model route adaptation; powertrain; charge strategies; simulation; hybrid vehicle; vehicle propulsion;

    Sammanfattning : For vehicles with energy storage devices, here referred to as hybrid vehicles, the control of the system is of great importance. The hardware system can not be judged without its control. This thesis describes a method for determining the potential of an arbitrary vehicle propulsion system for a prescribed driving mission.
