  1. 6. Minimisation of Chromium Leaching from Low-Alloy Electric Arc Furnace Slag by Mineral Modifications

    Författare :Ida Strandkvist; Fredrik Engström; Rainer Backman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slag; leaching; minerals; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Iron and steel are produced continuously as a vital part of modern life. The largest by-product of metal production is slag. Slag is an essential part of the production of steel since, in the furnace, the molten slag removes impurities from the metal. When the slag which consists of oxides, solidifies minerals form.

  3. 7. Analysis and control of a hybrid vehicle powered by free-piston energy converter

    Författare :Jörgen Hansson; Mats Leksell; Chandur Sadarangani; Anders Malmquist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-piston energy converter; FPEC; series hybrid electric vehicle; SHEV; power management; energy management; powertrain evaluation; equivalent consumption minimisation; ECMS; linear engine; Electrical engineering; Elektroteknik;

    Sammanfattning : The introduction of hybrid powertrains has made it possible to utilise unconventional engines as primary power units in vehicles. The free-piston energy converter (FPEC) is such an engine. It is a combination of a free-piston combustion engine and a linear electrical machine. LÄS MER

  4. 8. On power loss minimisation for heavy vehicles with axle-wise and modular electrical propulsion and friction braking

    Författare :Sachin Janardhanan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction brakes; powertrain; power loss; electric machines; Heavy vehicles; topology;

    Sammanfattning : The main challenges for battery electric heavy vehicles are improving the payload capacity and driving range for different applications. These are mainly influenced because of battery power density, different vehicle configurations, and powertrain design. LÄS MER

  5. 9. Privacy-Preserving Transparency-Enhancing Tools

    Författare :Tobias Pulls; Simone Fischer-Hübner; Stefan Lindskog; Jaap-Henk Hoepman; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Sammanfattning : Transparency is a key principle in democratic societies. For example, the public sector is in part kept honest and fair with the help of transparency through different freedom of information (FOI) legislations. LÄS MER

  7. 10. Statistical Physics of Protein Folding and Aggregation

    Författare :Giorgio Favrin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Two State; Physics; Fysik; Statistics; operations research; programming; aktuariematematik; programmering; operationsanalys; actuarial mathematics; Statistik; Simulations; Aggregation; Protein Folding; Fysicumarkivet A:2004:Favrin;

    Sammanfattning : The mechanisms of protein folding and aggregation are investigated by computer simulations of all-atom and reduced models with sequence-based potentials. A quasi local Monte Carlo update is developed in order to efficiently sample proteins in the folded phase. LÄS MER
