  • Modified Active Constellation Extension for PAPR Reduction of Space-Frequency Block Coded OFDM Systems 

    Ferdosizadeh Naeiny, M.؛ Jafarnia Jahromi, A.؛ Marvasti, F. (Sharif University of Technology, 2010-12-01)
    In this paper, the Active Constellation Extension (ACE) technique is applied to Space Frequency Block Coded (SFBC) OFDM systems to reduce the Peak to Average Power Ratio (PAPR). For the extension of this technique to ...

  • A New Evidential Distance Measure Based on Belief Intervals 

    Khatibi, Vahid؛ Montazer, G. A. (Sharif University of Technology, 2010-12-01)
    So far, most of the evidential distance and similarity measures proposed in the Dempster- Shafer theory literature have been based on the basic belief assignment function, so as the belief and plausibility functions as ...

  • Simultaneous Coordinated Tuning of SSSC-Based Stabilizer and PSS Using Quadratic Mathematical Programming 

    Shakarami, M. R.؛ Kazemi, A. (Sharif University of Technology, 2010-12-01)
    In a Static Synchronous Series Compensator (SSSC), a controllable AC voltage is generated by a voltage-source converter. There are two control channels for controlling the magnitude and phase of the voltage. When this ...

  • Artificial Neural Networks Based Dynamic Weight Estimation with Optical Arrangement 

    B. Bahar, H.؛ safari, E.؛ A. Ghazijahani, H. (Sharif University of Technology, 2010-12-01)
    In this essay, an optical arrangement for the measurement of dynamic weight, by means of conducting a thin ray of light through it, is designed in order to enhance the measuring accuracy in the weight-estimation device. ...

  • Microwave Photonics Mixing 

    Cabon, B. (Sharif University of Technology, 2010-12-01)
    The multidisciplinary eld of Microwave-Photonics is at the convergence of photonic and microwave or even wireless technologies. In this context, the processing, conversion and transmission of microwaves, as well as high ...

  • Ontological Classi cation of Network Denial of Service Attacks: Basis for a Uni ed Detection Framework 

    SADEGHIYAN, B.؛ Varshovi, A. (Sharif University of Technology, 2010-12-01)
    In this paper we introduce the notion of a detection framework to facilitate the reasoning and cooperation process of detection and response systems. The presented framework de nes four dimensions as requirements to be ...

  • An Accurate Guidance Algorithm for Implementation Onboard Satellite Launch Vehicles 

    Marrdonny, Mohamadd؛ Mobed, Mohammad (Sharif University of Technology, 2010-12-01)
    An algorithm for guiding a launch vehicle carrying a small satellite to a sun synchronous LEO is presented. Before the launch, a nominal path and the corresponding nominal control law for the entire journey are computed. ...

  • Separated Continuous Linear Programs with Fuzzy Valued Objective Function 

    Nasrabadi, M. M.؛ Yaghoobi, M. A.؛ Mashinchi, M. (Sharif University of Technology, 2010-12-01)
    Fuzzy linear programming problems can be used to model a wide variety of practical applications in which all or some decision parameters are stated in an imprecise fashion. These problems have been investigated and ...

  • Minimum Height Path Partitioning of Trees 

    Ashoor, M.؛ Razzazi, M. (Sharif University of Technology, 2010-12-01)
    Graph partitioning is a well-known problem in the literature. In this paper, path partitioning of trees in which the given tree is partitioned into edge-disjoint paths is considered. A linear time algorithm is given for ...
