  2. 11. On Medium Access for Wireless Ad-hoc and Sensor Networks

    Author : Arash Tahmasebi Toyserkani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MAC; Transmission range; Interference range; Taffic Safety; Sensor Networks; TDMA; CSMA;

    Abstract : The medium access control (MAC) is a sub-layer of the data link layer, thesecond layer of the open system interconnection (OSI) model. The MAC sub-layeris responsible for organizing the access to the shared channel and it is due tothis important responsibility that the performance of networks is substantiallyinfluenced by the MAC protocol.

  4. 12. Long-range decision models in mining

    Author : Nils-Erik Norén; Handelshögskolan i Stockholm; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Decision models for optimizing decisions in mining. Two principal models are presented:1) For optimizing the rate of production in a mine2) For optimizing the cut-off grade. The models are based on dynamic programming and simulate the economic consequences of alternative decisions. Computer programs containing the models are presented. READ MORE

  5. 13. Magneto-sensitive rubber in the audible frequency range

    Author : Peter Blom; Leif Kari; Luigi Bregant; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magneto-sensitivity; Rubber; Audible frequency range; Amplitude dependence; Vibration isolator; Fletcher-Gent effect; Stiffness; Acoustics; Akustik;

    Abstract : The dynamic behaviour in the audible frequency range of magneto-sensitive (MS) rubber is the focus of this thesis consisting of five papers A-E. Paper A presents results drawn from experiments on samples subjected to different constant shear strains over varying frequencies and magnetic fields. READ MORE

  6. 14. A Two-Stroke Range Extender Engine For Heavy Duty BEV applications

    Author : Lennarth Zander; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas exchange; after burner; single cylinder; Two-stroke engine; Range extender; BEV; Battery electric vehicles;

    Abstract : A back-up range extender (REX) is proposed to support battery electric vehicles (BEV) for heavy duty applications. A single cylinder crank case scavenged two-stroke SI-internal combustion engine (ICE) with a turbocharger system is considered powerful and small enough to be installed directly on the existing electric machine in the electric powertrain.
