In this paper we have proposed modified optical conductivity model of graphene and simulated surface-plasmon polariton (SPP) mode propagation for different chemical potentials. We have approximated the critical value of chemical potentials which is responsible for (SPP) propagation in Single layer straight and double layer 90 Degree sharp bending using Finite Difference Time Domain method (FDTD) with SBC-Perfectly Matched Layer (PML) technique. The possible application of SPP for the plasmonic devices is discussed.

The usage of the AC induction motor (ACIM) becomes widely increased in the industrial applications as well as domestic usage, due to the new technologies of the electronic switching technologies. The speed of the ACIM is achieved through the control of the frequency of the applied voltage to the IM, this is achieved by using the inverter, whose output frequencies lies between (20 and 60) Hz. The performance of inverter will be enhanced by adding a Hybrid Fuzzy Logic Controller and PID controller to enhance the speed controller of the ACIM. A Hybrid fuzzy logic controller (FLC) and proportional-integral derivative (PID) control of an inverter for single phase AC Induction motor is described in this paper. The output voltage error and its derivative are used as input variables for the FLC to adjust the error of the system, it will be added to the output of the PID controller to enhance the performance of the system and minimize steady state error for the speed of the motor. Microcontroller (PIC16F877A) was used to generate the pulse width modulation (PWM) and to generate internal sine wave with variable frequency to control the speed of the motor accordingly.

This paper inspects a signal processing approach to determine number and distance of objects in the sea. Determining number and distance of objects in the sea are two key factors for underwater communication. Now-a-days navigation, marine experiment, fisheries, detective purposes and many other works in under water are highly dependent on this determination. However, including SONAR some conventional techniques are used in these purposes, sometimes, these techniques are complex as well as costly. Here, we try to show a statistical tool called cross-correlation technique, which is, on the other hand, a significant aspect in signal processing approach. The cross-correlation technique is used in this determination process. We transmitted CHIRP signal and used its echo effect in order to determine the number and distance of the objects in the sea. We have verified this proposed theory by a simulation from the MATLAB programming environment.

In the analysis of cascading failure, the multiple failures is necessary to take into account under a certain condition, and the occurrence probability and severity of multiple failures are varies with the change of operating mode caused by equipment maintenance. In this paper the event tree is used in the analysis on cascading failures and by use of probability approximation theory of rare event the probability order of multiple failures is divided, thus the screening process of multiple failures can be simplified. Applying this method to the analysis on cascading overload and from the case simulation results it can be seen that the proposed searching method can reflect the variation of failure probability caused by the change of operating mode well, and assess the risk of equipment maintenance better, thus the path searching of low-probabilistic and high-risk cascading failures can be further improved. The proposed method may be helpful for the research on cascading failures in depth.

This paper presents an optimum design for dispersion managed photonic crystal fibers with low confinement losses. The COMSOL multi-physics 4.2 software is used as the simulation tool. According to simulation, a five-ringed modified hexagonal photonic crystal fiber (MH-PCF) having germanium (Ge) doped silica core can be designed with a low confinement loss at 1550 nm of the order 1.026×10-14 dB/km with simultaneously nearly-zero ultra-flattened chromatic dispersion of 0 ± 0.35 ps/nm/km in a wavelength range of 1.30 to 1.65 μm as well as large effective area in a wide range of wavelengths. The fiber having a modest number of design parameters is suitable for wavelength division multiplexing (WDM) system.

Mean frequency (MNF) based EMG power spectrum analysis is presented to determine Salat associated muscle fatigue and indices. The main complexity of the parameter is a non-linear relationship between muscle fatigue and feature value, especially in large muscle and in cyclic dynamic contraction which is solved by this proposal. By this work, we can compute frequency dependent MNF for dynamic contractions and relaxations. Through Acknowledge software, FB-MNF is calculated and compared with the standard MNF. The results demonstrate that mean parameter of selected FB-MNF has a better linear relationship with muscle contraction compared to the others for different subjects. In addition, it has been observed through analysis of variance (ANOVA), compared to the traditional methods and have a significant difference (p<;0.05) between feature values among the MNF signal data of EMG power spectrum for different subjects. Furthermore, we have computed Mean Power (MNP), Total Power (TTP) and Peak Frequency (PKF) to determine both muscle load and muscle fatigue indices.

Renewable energy has to perform pivotal role in the development of present world as the globe has limited amount of fossil fuel. Wind energy is one of the prospective clean energy to provide reliable power but the intermittent nature of wind generation makes its operation and planning a major challenge to use wind as a source of power. In order to develop power system stability, it is essential for wind farm to control the frequency. In a power system different types of governor control system are used and their characteristics are also different. So, this study investigated the combined effect of different types of governor control system on the power system stability. It is examined that wind generator capacity can be increased up to 15% of the total capacity by maintaining frequency fluctuation to the acceptable limit using several number of wind generators connecting in parallel instead of similar capacity single wind generator.

In cognitive radio communication, energy and time consumption has a key role to ensure reliable primary user signal detection. A two stage (coarse fine) spectrum sensing has drawn well-deserved attention for wideband cognitive radio communication. In this paper, it is analyzed the required time and energy for sensing, switching and transmission for wideband channel with different practical scenario by coarse fine sensing. Moreover, we have proposed multi antenna assisted energy detection based signal detection for coarse fine sensing in the fading environment. An effective solution is developed by utilizing multiple antennas to minimize the sensing time and energy consumption while maintaining the quality of service (QoS). The proposed method improves the efficiency to obtain desired vacant band for data transmission with low energy compared with conventional system.

Electromagnetic (EM) fields at a point in space generated by electric/magnetic dipole embedded in a general anisotropic stratified media can be analytically solved [1] by decomposing the fields into transverse electric (TE) and transverse magnetic(TM) modes. The electromagnetic field strengths are dependent on the nature (electric or magnetic) of dipoles, their placement in the stratified media, and relative location of dipoles. A three-layer stratified media has been employed in this paper to model the environment consisting of air, seawater, seabed. The mathematical formulations provided by Tang [1] are used for EM field calculation containing both magnitude and phase information of Ẽ and H̃ fields for dipole antenna of 4 types namely: horizontal magnetic dipole along x- direction (HMDx), horizontal electric dipole along x- direction (HEDx), vertical magnetic dipole (VMD) and vertical electric dipole (VED). Parametric computational investigations are presented to delineate effects of i) the electric and magnetic properties of the media, ii) the nature and orientations of dipole sources, on EM fields at a specified observation point. It is observed that contributions from horizontal electric dipoles have comparable electric and magnetic field strengths at an observation point in the air.

This study presents a simple type of modified PCF (M-PCF) as a chemical sensor where both core and cladding are micro-structured. Different guiding properties of proposed M-PCF have been investigated for a wide range of wavelength using full vectorial finite element method (FEM). By varying pitch and hole diameter both of inner and outer layers, the relative sensitivity, refractive index and confinement loss are numerically examined and compared. At the wavelength 1.33μm it is observed that the relative sensitivity is improved 1.45 times and confinement loss is also reduced than prior work. Fabrication process and cost will be low of proposed M-PCF because of its structural simplicity.
