In the present scenario, power quality is an important element of power system. Different nonlinear devices like diodes, rectifiers, and furnaces are generating power fluctuation, voltage sag and swell concerns, load imbalance, voltage imbalance, and other power quality issues, which may be controlled by FACTS devices such as DVR, STATCOM, Active power filter, UPFC, and UPQC. In the present work, application of DSTATCOM in the distribution network to overcome power quality issues, meeting the reactive requirement of the load to raise power factor to unity are addressed. A novel Sinusoidal PWM (SPWM) control technique is employed to reduce the harmonics in the distribution network. It relies on weighted value convergence and is unaffected by carrier signal characteristics. In this paper, four different cases have been considered with varying supply voltages. The simulation results show that D-STATCOM works efficiently and offers very less THD for different power quality problem like voltage sag, swell, load imbalance, voltage fluctuation etc. The Voltage Source Converter is regulated using the Sinusoidal PWM method. The result indicates that the DSTATCOM and SPWM control technique is helpful for power quality improvement.

The design of a simple and efficient metasurface absorber at terahertz (THz) frequencies is an extremely difficult job. In this work, an effort has been made to design and investigate a new kind of absorber with the aid of a graphene-inspired tunable metasurface at THz frequencies. Critical performance analysis of absorber has been carried out in terms of absorptivity, normalized impedance, polarization insensitivity, and angular stability. A graphene-metasurface absorber has been found to possess an absorptivity of 96% at 6.1 THz with a corresponding absorption bandwidth of 1.4 THz. The total thickness of the absorber is only 10.2 µm accomplished with the help of a very simple design. Besides, the impact of graphene's chemical potential has been studied up to 0.7eV. The outcomes reflect the tremendous capability of the proposed metasurface configuration for THz applications.

The magnetic state in the Permanent Magnet Fault Current Limiter (PMFCL) changes from saturation to unsaturation when fault occurs in the system. Due to this nonlinear characteristic undesirable harmonics are generated in the system. This paper represents the effects of shorting ring associated with the Permanent Magnetic Fault Current Limiter for diminishing the harmonics generated in the circuit. The simulations are done using Finite Element Method (FEM) considering the hysteresis loop of the core.

Next Generation Wireless Networks are heterogeneous in nature comprising of various radio access technologies. There has been exponential growth in the number of mobile users in the recent years and the users demands have been ever-growing. Keeping multiple mobile applications running simultaneously, while the users are on the move, require high bandwidth and seamless connectivity. Connectivity to the best network among the available networks can be ensured by having an efficient Vertical Handover Decision Algorithm. The choice of the best radio access network depends upon various parameters like Received Signal Strength, Channel capacity, Cost, Quality of Service and Network coverage. Vertical Handover Decision Algorithm is an important constituent of the network architecture in heterogeneous wireless networks. In this research paper, the authors have implemented Vertical Handover Decision Algorithm using Simple Additive Weighting (SAW) and Multiplicative Exponential Weighting (MEW) techniques.

The search for low-cost practical radar absorbing structures (RAS) to decrease electromagnetic (EM) emissions has aroused interest. To strengthen electronic waste (e-waste) treatment and explore wideband absorber structure, perforated RASs are proposed and modelled with the magneto-dielectric properties of microwave heat treated e-waste composite. The investigation of proposed structures is carried out in 8.2 to 12.4 GHz (i.e., X-band). The thin and wideband single layer RAS is optimized with the help of multi-objective Jaya's optimization algorithm. As an outcome, a −16.8dB reflection coefficient (RC) is achieved in 2.4mm thick grid type RAS at 10.2 GHz exhibiting a −10dB bandwidth of 4.2 GHz. Furthermore, at a fixed optimized thickness, the proposed RAS is also examined against various oblique angles of incidence and found to be prominent. The full-wave simulation is utilized for the validation of optimized results and both are in good agreement with each other. The addition of a circular air gap in the structure regulates the composite EM characteristics at a higher frequency. It demonstrates that cavitation has magnificent advantages for the creation of wideband, lightweight, and low expense RAS for the stealth technology.

This paper describes, a wide-range low voltage Wilson Current Mirror based reflected-output Level-Shifter for swift and cost-effective voltage translation from sub-threshold level to input-output supply voltage. The level-shifter that can translate sub-threshold voltage to level of supply voltage is modeled to reduce circuit delay as well as power leakage with optimal transistors count in the designed circuit. Wilson current mirror level-shifter is designed in 0.18µm CMOS technology and is implemented using simulator such as Cadence Virtuoso & LTspice. The simulation results show that designed model can effectively translates the input low voltage levels (as minimum as 50 mV) to around 1.8 V at output levels without utilizing some multi-threshold models. The total power utilization and delay of the designed Level-Shifter of a 0.3 V / 1 MHz input level and response level (1.8 V) are 80.23 nW and 6.9 ns respectively. Also, comparative study is performed with the other designed level shifters which shows the cost-effectiveness of the designed model.

Textural segmentation and its usage for region-wise image quality improvement unfold a new chapter for texture-dependent image processing in association with fractional order calculus (FOC). Along with intensity variation, texture variation is also equally important for human as well as machine vision to discriminate between surfaces and objects even having the same intensity. Most of the vision applications deal with intensity-wise segmented frames as their raw input. The power of textural analysis along with conventional intensity-based processing can enhance the system's capability in a remarkable manner. To address the textural nature of the image and for imparting texture-dependent image restoration or enhancement fractional-order high-boost filtering (FoHBF) the framework is essentially relevant irrespective of the image domain. Spatial entropy quantile-based textural segmentation and region-wise FoHBF is employed in this paper for imparting total quality enhancement, especially for remotely sensed images.

In this paper, an adaptive RBF neural network-based sliding mode control scheme is implemented over STAT-COM to improve the voltage response of an isolated wind-diesel power system. Sliding mode control as a robust control scheme is developed on the basis of switching surface design, however, it leaves the drawback of chattering. Therefore, RBF neural network is used as adaptive control along with traditional sliding mode control to obtain the improved and chattering free voltage response. Simulations using MATLAB are carried out and the performance of the system is evaluated with the system exposed to load and wind power disturbances.

In this paper, L-pulse position modulation (PPM) is implemented with angle diversity transmitter based visible light communication (ADT-VLC) system in indoor environment. The error performance of ADT-VLC system using L-PPM modulation with perfect and imperfect CSI is presented. The closed-form expressions for BER of ADT-VLC system using L-PPM modulation with perfect and imperfect CSI are derived. In the presence of perfect and imperfect CSI, the error performance of an ADT-VLC system using L-PPM modulation is compared to an ADT-VLC system using OOK modulation. Effect of different channel estimation error values on BER of the proposed system is analyzed. The SNR distribution of ADT-VLC system using L-PPM modulation is also evaluated for higher modulation order. The analytical and simulated findings are comparable.
