  • DALD:-Distributed-Asynchronous-Local-Decontamination Algorithm in Arbitrary Graphs 

    Rahmaninia, M.؛ Bigdeli, E.؛ Zaker, M. (Shahid Rajaee Teacher Training University, 2014-04-01)
    Network environments always can be invaded by intruder agents. In networks where nodes are performing some computations, intruder agents might contaminate some nodes. Therefore, problem of decontaminating a network infected ...

  • The Application of Multi-Layer Artificial Neural Networks in Speckle Reduction (Methodology) 

    Pishgoo, M.R.؛ N. Avanaki, M.R.؛ Ebrahimpour, R. (Shahid Rajaee Teacher Training University, 2014-04-01)
    Optical Coherence Tomography (OCT) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. An inherent characteristic of coherent imaging is the presence of ...

  • A-New-Closed-form-Mathematical-Approach-to-Achieve Minimum Phase Noise in Frequency Synthesizers 

    SamadiGorji, S.؛ Zakeri, B.؛ Zahabi, M.R. (Shahid Rajaee Teacher Training University, 2014-04-01)
    The aim of this paper is to minimize output phase noise for the pure signal synthesis in the frequency synthesizers. For this purpose, first, an exact mathematical model of phase locked loop (PLL) based frequency synthesizer ...

  • Optimum Design of a SRM Using FEM and PSO 

    Ranjkesh, M.؛ FallahChoolabi, E.؛ Pourjafari, M. (Shahid Rajaee Teacher Training University, 2014-04-01)
    Nowadays the use of the Switched Reluctance Motors (SRMs) has been considerably increased in various home and industrial applications. Despite of many advantages of this type of motors, such as simple structure, low cost, ...

  • THD Analysis in Closed-Loop Analog PWM Class-D Amplifiers 

    Amiri, P.؛ Kohestani, M.؛ Seifouri, M. (Shahid Rajaee Teacher Training University, 2014-04-01)
    In this paper, we investigate the parameters affecting Total Harmonic Distortion (THD) and Power Supply Rejection Ratio (PSRR) in PWM Class D Amplifiers (CDAs) on the basis of linear models with feedback. From our mathematical ...
