This paper introduces three-phase induction motor drive system with function of harmonic current injection for non-linear load using Matlab/Simulink. The drive system consists of two converters. A single-phase grid-connected converter which is the first converter in the drive system is regulated by PI controller of DC-link voltage control loop, and switched by hysteresis control. Moreover, the converter is able to generate harmonic current to eliminate harmonic current in grid with harmonic detection algorithm. The other is three-phase three-leg voltage source inverter for three-phase induction motor drive controlled with close loop V/F speed control. The simulation results revealed that the motor could keep speed constant rated speed, having been taken rated load torque at 10 Nm. Furthermore, the grid converter could keep DC-link voltage constant at 540 V for rated voltage of the motor, improved grid current waveform being like sinusoidal waveform and eliminated harmonic of grid current.

The study on the concentration changes of the radioactive substance 18F-FDOPA in striatum is one of the important technique to diagnose the Parkinson’s disease (PD). In research, the compartment model is applied to study the area proportions of 18F-FDOPA through the brain in the striatum area and consider different concentration levels at a given time t. In particular, we adopt compartmental dynamic model to study the behaviour of 18F-FDOPA over times after the injection. We also compute the modelling errors and give subsequent discussion about our results.

In this research, a genetic algorithm combined with a method of moments (MoM) software were utilized to optimize a microstrip patch antenna with a complicated structure to achieve tri-band characteristic. The design consisted of a probe-fed air-substrate single-layer patch antenna loaded with three asymmetrical U-slots. When the three U-slots with appropriate dimensions were suitably placed on the patch, three desired bands formed. The optimal solution to the design problem was obtained by using the genetic algorithm. The optimization strategy and procedure used in this work are discussed. The simulation of the antenna operations was performed to verify the reliability of this optimization method. The proposed antenna provided three bands at 1.935 − 2.027 GHz, 2.59 − 2.705 GHz and 3.106 − 3.289 GHz with the maximum gains of 8.34, 8.75 and 7.56 dBi respectively, at the center frequencies of each band. The proposed antenna is applicable for WCDMA and WiMAX applications.

This paper describes the investigation of a frequency reconfigurable equilateral triangular microstrip patch antenna (ETMPA). An equilateral triangular microstrip patch is designed using C-shape slots based DGS ground structure to enhance the bandwidth requirements. Here the frequency reconfigurable triangular microstrip patch antenna is proposed by modifying the C-shape slots width by using two MPP4203 RF PIN diodes. The frequency reconfigurability of DGS ground based ETPA is analyzed at 1.93 GHz and 3.78 GHz for L and S band based satellite and 4G mobile communication (E-UTRA 43 band), respectively. The Ansoft HFSS simulation based radiation patterns shows a gain of 2 dB at 1.93 GHz and 2.4 dB at 3.78 GHz resonant frequencies for proposed triangular microstrip patch design.

Emergency settings are actually being strengthened by using Information and Communication Technologies (ICT) for the dynamic deployment of a Public Safety Network (PSN). A PSN is built on top of existing public service networks to help first responder teams in performing critical tasks. However, current solutions expose limitations when starting-up a PSN such as provisioning effective communication links for first responders, as key point to successful emergency management, as well as incorporating autonomous self-management capabilities to decide when, where, and how to deploy emergency services dynamically. In this context, this paper reviews the current state of the art and showcases the main challenges for PSN provision, taking into account new 5G mobile networks to deploy virtualized emergency services in future mobile communications dynamically.

This work explores the photonic enhancement of a nitrogen-vacancy center quantum emitter in order to achieve improvement in photon collection efficiency. Finite element methods were used to simulate the effect of diamond nanopillars on the emission pattern and the resulting collectible photon efficiency. All emitter dipole orientations in a <111> diamond substrate were considered, with nanopillar diameters ranging from 10 nm to 1000 nm. When compared to the bulk emission, the collection efficiency was found to have an optimal enhancement of up to 60%, which is nearly 4 times the intrinsic bulk emission value for on-axis nitrogen-vacancy centers. The collection efficiency enhancement in these proposed structures could improve the measurement fidelity of the quantum state, resulting in advancement toward real-world applications of quantum technology.

This paper presents the optimal fractional order model identification of the pressure process control system by the cuckoo search (CS) algorithm. The accurate model the pressure process control is required for analysis and design. The fractional order model is based on the fractional calculus. Therefore, the orders of transfer function model can be extended from integer to real number. Consequently, the fractional order model is more accurate than the integer order model. The fractional order system identification problem can be set as the modern optimization problem. The objective function receives from the integral of the absolute error (IAE) between the output of actual pressure process control and the output of candidate model within search space. The CS algorithm solves the optimal parameter of the fractional order model of the pressure process control in order to minimize the objective function. From simulation results, the fractional order model identified by the CS algorithm can give high accuracy, once compared with the integer order model identified by the CS algorithm.
