A metamaterial rod as a superstrate consisting of a periodically cylindrical rod is proposed for gain enhancement of omnidirectional microstrip patch antenna. The metamaterial rod exhibits near zero permeability that it reflects partially wave. This designed technique could be confirmed by a measurement result from prototype antenna that agrees with simulation results. The results indicate that the metamaterial rod can also enhance the radiation characteristics and efficiency, the proposed antenna generates an omnidirectional pattern in the azimuthal plane with the maximum gain of 19.47 dBi. The frequency of a high gain omnidirectional antenna using metamaterial rods is designed at 920 MHz for prepaid mobile application.

The paper presents the control of shunt active power filter using the sliding mode controller. The instantaneous power theory is applied for harmonic detection to calculate the reference currents. The dynamic models of the shunt active power filter on three-phase and dq frames are proposed in the paper. The model on dq frame is used to derive the control strategy. Moreover, the stability criterion using the Lyapunov unction is also presented in the paper. The simulation results show that the proposed controller can reduce the %THD of source currents after compensation and it can regulate the DC bus voltage of shunt active power filter.

The benefit of a Full-Duplex Single-Channel (FDSC) system is the double throughput because it can transmit and receive simultaneously at the same time and on the same frequency. However, the expense of FDSC system is on the very strong self-interference signals due to the leakage of transmitting signals that interfere the receiving signals. Moreover, for MIMO systems, the problem of interferences is severely considered due to multiple transmitting and receiving antennas. So far in literatures, there have not been any suitable techniques presented to reduce the self and mutual interferences for FDSC MIMO systems. This paper present the performance of self and mutual interference cancellation by utilizing the mutual coupling model. The interferences can be eliminated by using pre-known interferences that are the mutual coupling signals. The results indicate that the channel capacity performance of the proposed technique can significantly be improved due to the reduction of the interference power. The measurement results indicate that the proposed FDSC MIMO system can suppress the self and mutual interferences signals with the reduction of 29.84 dBm received power.

In battery-operated electric vehicles, a regenerative brake system is an additional feature that recovers kinetic energy back to the battery energy storage. Due to losses in the cyclic charge/discharge of battery characteristics such processes give low energy conversion efficiency. Supercapacitor, on the other hand, has an advantage over battery in terms of recovering an intermittent energy like a regenerative braking. This work aims to examine charging/discharging efficiencies of supercapacitor in both stand-alone and hybrid modes. Experimental results have verified that supercapacitor is suitable for a storage device in electric vehicle.

Transaction-level Modeling (TLM) and bus functional modeling (BFM) are widely-used techniques for functional verification of digital systems. Many modern systems-on-chip (SoC), network-on-chip (NoC), application-specific integrated circuit (ASIC), and field-programmable gate array (FPGA) designs have been verified using these techniques. However, transaction-based techniques have almost always [1]-[14] been used only for simulation of digital designs, and until recently, were not used to design physical hardware. This paper introduces a technique to develop transaction-based hardware. With this method, the same transaction-based model can both be simulated and synthesized to hardware. Several SoC/NoC subsystems can easily be interconnected in basically the same manner as how transaction-based simulation models are being written. This approach brings the benefits of transaction-based verification (TBV) to the hardware design engineers, resulting in a greater level of simplification for complex designs.

Alternating current electroluminescent (AC-EL) display is a leading-edge technology for flat and flexible large-area light source. The AC-EL display offers high luminance with relatively low power consumption, lightweight, high resolution, good contrast and brightness, and long lifetimes. In this work, a flexible AC-EL display has been fabricated by screen-printing method. The various parameters to affect the efficiency and luminance intensity of the AC-EL have been investigated. The results show that an increase of applied voltage excitation enhances AC-EL illuminance while high excitation frequency plays an important role for high luminescence intensity. The sinusoidal signal drive also offers better illuminance than square wave drive. The relationships of voltage, waveform, and frequency with the light-emitting efficiency have been discussed in more details under systematic experiments.

This paper presents the simplified active power and reactive power control with the maximum power point tracking (MPPT) for three-phase grid-connected photovoltaic (PV) inverters. With the proposed control strategy, the perturbation and observation method is used for the simple MPPT algorithm and the current command on the rotating reference frame is regulated by the feedback and feedforward controller. In order to guarantee the all maximum power is transferred to the grid, the d-axis current or active power command is calculated from the PV power. Moreover, the design guidelines of phase-locked loop (PLL) and current controller are also presented. Validity of the proposed grid-connected inverters is confirmed by simulation.

Accuracy of location determination is one of the keys to success of any indoor positioning system. This performance metric is influenced by how reference nodes (RNs) are installed. However, most of existing research studies ignored the problem of optimal reference node placement and efficient system design for indoor positioning systems. In this paper, we propose an optimization technique that can be used to optimize the placements of reference nodes and improve the location determination performance. A mathematical formulation of reference node placement is developed as a Binary Integer Linear Programming (BILP) problem, which is an efficient approach generally applied in facility layout problems. The proposed formulation aims to minimize the number of reference nodes and search for their optimal locations in indoor positioning system. The performance study in this work is based on simulation model comparison of node placements found in the literature with the optimal node placement solutions obtained from our optimization. The results show that using optimal placement of reference nodes the indoor positioning systems can gain up to five meters of accuracy at 90% precision.

The objective of this paper is to analyze the performance of multi-input converter during fault condition at hybrid power systems. Multi-input converters are fed with several sources of energy. During fault phenomenon, the voltages of energy sources become zero. So, the output voltage of mentioned converter is affected by this change. In this paper, at the first step, one hybrid PV/Wind power system has been proposed and simulated in MATLAB/Simulink. In this part, the simulation process of the power sources and double-input DC/DC converter has been explained. The other issue which is studied at this part is introducing of a proper control strategy for the simulated double-input DC/DC converter. There are some important factors to design the controller. These factors have been studied and based on these studies; the controller is designed. The last session of this survey relates to the studying of the fault effects on multi-input converter. At this part, by inserting the fault on power sources under different conditions, the output voltage and power have been analyzed. In addition, studying the dynamic and stability of designed controller is the other part of the last session.

Writing process in hard disk drives (HDD) is affected from nonlinearity. Normally, nonlinearity is not easy to be avoided or removed since it is unexpected and caused by various sources. In this paper, we review a description of a nonlinearity behavior by using a Volterra model, and using a random binary number to generate an input data. The Volterra model can describe both linear and nonlinear parts of the read-back signals in terms of the volterra equations. In addition, we propose to use an MMSE method to equalize the read-back signals with nonlinearity using various constraints before applying the Viterbi detector. For a 2nd-order Volterra model, the results show that the equalizer with g1 =1 constraint gives the lowest MMSE values. Furthermore, as the nonlinearity level increases, the bit error rate (BER) performance degrades.
