    Abstract: This paper proposes, a DFT-based OFDMA with phase modulation (DFT-OFDMA-PM) system. One main advantage of the phase modulated system is the constant envelope (CE) resulted signal, i.e, 0 dB PAPR, the second advantage is the ability to improve the diversity of multipath channels. These advantages have been exploited in the proposed system of this pa... Show More

    Abstract: In response to the controversy over whether machines can think and the queries on artificial intelligence (AI), this paper clarifies that the essence of simulation and AI (i.e. simulation intelligence) should be pursuing assimilation (similartaxis) as well as keeping dissimilation to a prototype (natural intelligence). Both commonness and obvious o... Show More

    Abstract: In the newfangled world, electrical energy is the most important thing, and we cannot live without it. The recent research has predominated that petroleum by-products are available only for a few hundred years. This paper is especially clear to meet out that. After some years, the mineral oil in the transformer needs to be changed due to its degrad... Show More
  • Fault Location in the Transmission Network Using a Discrete Wavelet Transform

    Published: Jun. 25, 2019
    Abstract: In this paper, a discrete wavelet transform (DWT) has been utilized for processing the current signal in order to fault-location evaluation in network transmission using pre-fault and post-fault current data of both the terminals of a transmission line. In fact, the basis of the work is based on the information recorded before the fault at the end ... Show More
  • An Efficient Fault Detection of FPGA and Memory Using Built-in Self Test [BIST]

    Published: Jul. 02, 2019
    Abstract: In this paper, a new technique for localization of fault detection and diagnosis in the interconnects and logic blocks of an arbitrary design implemented on a Field-Programmable Gate Array (FPGA) using BIST is presented. This technique can uniquely identify any single bridging, open or stuck-at fault in the interconnect as well as any single functi... Show More
  • Tuning Pi Controller Bases on Chemical Reaction Optimization Algorithm

    Abstract: This paper we present Chemical Reaction Optimization (CRO) algorithm for determining optimal parameters of PI controller. The model of doubly fed induction generator (DFIG) is used as a plant in this paper. Tuning PI controller using traditional method such as Ziegler-Nichols (ZN) method usually produces large overshoot and Integral time absolute e... Show More
