Metaheuristics algorithms are the most popular and robust algorithms for the optimization of the real world problems like pitch control of an aircraft system. This paper introduces Differential Evolution technique for the weighted multi-objective optimization based designing of the fractional order PID controller. The optimized values obtained from the techniques have been implemented for the Pitch control of an aircraft system to obtain the desired robust response. In this paper a mixed sensitivity H∞ problem is designed and simulated using Matlab. It has been shown that the design of FOPID using multi-objective Differential Evolution technique gives better results than tuning of classical PID using Differential Evolution.

In the present study, the aim is to demonstrate the application of the Adomian Decomposition Method (ADM) to obtain a closed form solution of a stepped fin space radiator with temperature-dependent thermal parameters. The effect of internal heat generation is also considered. The thermal conductivity and surface emissivity are considered to be linearly-dependent on the temperature. For validating the employed methodology, the simplified ADM results from the present study have been compared with relevant results available in the literature, which are found to be in good agreement. The effect of pertinent performance parameters such as thickness reduction factor, step length ratio, aspect ratio, radiation-conduction, non-dimensional thermal conductivity and emissivity parameters along with heat generation number on the temperature distribution has been reported. Furthermore, the temperature distribution of the stepped fin space radiator has been compared against that of the straight fin space radiator. It has been found that the local temperature distribution in case of a stepped fin is less as compared to that of a straight fin space radiator. Thus, from enhanced heat transfer point of view as well as from less weight consideration, a stepped fin space radiator is concluded to perform better than a straight fin.

The analysis of a permanent magnet synchronous motor (PMSM) for the traction application with wheel slip control has been presented in this paper. The application demands of Permanent magnet synchronous motor (PMSM) drives in electric traction have been increased to a great extent. The proposed PMSM drive has been integrated with the traction load model which provides us with extremely useful insight into the nature of traction load. The simulation results clearly indicate a high load torque during the acceleration which reduces once the acceleration period is over and the train resumes pure rolling motion. The proposed traction drive has been modeled with wheel slip control strategy which demonstrates how the wheel slip ratio can be controlled to make optimal use of force of adhesion between train wheels and track so as to allow maximum acceleration. The proposed scheme has been modeled to operate at any desired slip. The traction drive accelerates under the influence of slip ratio controller at the desired slip until the reference speed is reached. Once the train reaches the desired speed, the speed controller takes control and maintains the speed at desired value.

This paper has focused entirely on Swarm Intelligence based routing protocols especially Bee-Inspired based routing protocols for providing multipath routing in Wireless ad hoc networks (WANETs). WANETs influence an agent-based routing protocol that defines numerous rules including that most the participating nodes follow. Using routing technique, nodes are interconnected jointly so for that reason reduces computational and resource costs. Swarm Intelligence uses agent-like entities from insect's societies to become metaphor to refurbish the routing problem. But it is been observed the fact that Bee-Inspired routing has not yet used compression algorithm to make use of the bandwidth in more proficient manner. Therefore this paper has proposed a LCBEEIP protocol that is utilized BEEIP protocol with the feature of Loss Less data compression. The experimental brings about the proposed technique have clearly shown the fact that proposed technique outperforms over the current techniques. The proposed method has achieved up to 99.9167 packet delivery ratio.

Security and surveillance related technologies are rapidly growing day by day in the modern world to provide the security to the person and to the property. The biometric system is the only one that can provide accurate, secure and reliable scheme for personal verification. Biometric systems are broadly categories into two types: Uni-modal and Multi-modal. By comparing both these systems, it is clear that multi-modal biometric systems are gathering more popularity as it has the capability of dealing challenges involved in uni-modal biometric systems such as: non-universality, captured data noise, variations between same class, spoof attacks and unacceptable error rates. This paper will discuss various levels of information fusion, fusion techniques used at different levels and comparison among these fusion levels.

As sensor nodes are resource constrained, so it is mandatory to use these resources in an efficient way. Energy consumption is one of the important metrics that needs to be utilized carefully, to prevent connectivity holes. Many location based energy aware routing protocols (PAGER-M, GEAR, OGF, ALBA-R) already developed to route data packets, minimize energy consumption and to extend the lifetime of sensor nodes. These protocols do not consider the death of first node as a metric and there is unbalanced energy consumption among the sensor nodes. As a result, some nodes drain out their energy which leads to the connectivity holes in the network. In this paper, we developed BERP (Balanced Energy Routing Protocol), a protocol for energy efficient routing in wireless sensor networks. To balance energy among nodes, this protocol selects alternative paths to deliver data from source to destination. In addition to this, BERP checks the energy level of all sensor nodes continuously and declare the node as a connectivity hole whose residual energy is nearly zero. This protocol broadcasts the information of connectivity holes in the network. The simulation results confirm that BERP performs better in terms of packet delivery ratio, end to end latency, energy consumption and throughput.

Compact and multiband antennas are effectively demanded in wireless handheld devices for multiband operations. The design of multiband Planar Inverted-F Antenna (PIFA) for mobile handheld or portable devices applications is presented in this paper. The designed antenna comprises of a rectangular planar element placed above the Rogers Duroid 5880 substrate. The ground plane resides at the bottom side of the substrate. The ground plane dimension is 37×35 mm2 which makes it a very compact antenna. The antenna provides a multiband operation for covering the DCS1800 UL band (1.70 GHz), 4G LTE (2.3 GHz), WiBRO (2.35 GHz), Wi-Fi/Bluetooth 802.11g (2.4 GHz), m-WiMAX (2.5 GHz), WiMAX (3.5 GHz) and Wi-Fi 802.11a (5.2 GHz) communication standards. The proposed antenna is simulated & fabricated. The simulated and fabricated results are in good agreement with each other.

Data security has become the major issue now in these days, especially for the use of internet. Now trending, cloud computing needs secure, fast and area efficient cryptographic techniques.

The recent advances in power electronics have led to the development of the Flexible Alternating Current Transmission Systems (FACTS). FACTS devices require fully rated capacitor and reactor banks in order to supply/absorb reactive power. These requirements can be escaped by employing solid state synchronous voltage sources. The family of FACTS devices based on Voltage Source Converters (VSC) consists of STATCOM, SSSC and UPFC. The high cost of these VSC based FACTS controllers is found to be the major hindrance to their widespread use. Novel and cost effective converter based FACTS topologies have been proposed which make use of presumably existing passive components also and thus regarded as hybrid in nature. The different HPFC configurations devised by the investigator have been implemented on a Multi-Machine system and simulated using MATLAB/ SIMULINK. The comparison of simulation results shows that HPFC is a better option for damping power system oscillations and thus enhancing the stability of the system.

Due to the frequent usage of mobile phones these days, its harmful effects on biological systems has become a rising concern. Various international organizations like International Commission on Non-ionizing Radiation Protection (ICNIRP), U.S. Federal Communications Commission (FCC) and Institute of Electrical and Electronics Engineers (IEEE) have set safety guidelines on portable devices to limit the harmful effects of Radio Frequency (RF) radiations. Specific Absorption Rate (SAR) is a quantity that has been used by researchers to evaluate these safety limits on mobile phones. Exceeding these limits, leads to detrimental effects in biological systems. This paper discusses effects of RF radiations emitted by mobile phones on human body in terms of their SAR values. The SAR values are computed on human models to evaluate their effect on various body organs. Parameters affecting SAR values like age-related differences in RF absorption in human head models, mobile antenna tilt angle with respect to head and effect of using mobile phones inside elevators have been discussed. Moreover, methods for SAR reduction to limit RF exposure have also been analyzed.
