Shrinking hyper-sphere based Artificial Bee Colony algorithm

Abstract: Artificial Bee Colony (ABC) is a popular swarm intelligence based approach used to solve nonlinear and complex optimization problems. It is a simple to implement and swarm based probabilistic algorithm. As the case of other swarm based algorithms, ABC is also computationally expensive due to its slow nature of search process. The solution search equation of ABC is significantly influenced by a random quantity which helps in exploration at the cost of exploitation of the search space. Therefore, to balance the exploration and exploitation characteristics of the ABC, Shrinking Hyper-Sphere based local search approach is developed and hybridized with in the ABC solution search process. The proposed algorithm is named as Shrinking Hyper-Sphere based ABC (SHABC). The experiments over 14 well known benchmark functions of complex in nature, show that the SHABC algorithm perform better than the original version of ABC and its latest variant, namely Modified ABC (MABC) in most of the experiments.

A novel design of micro-gripper with enhanced displacement

Abstract: This paper presents performed design simulation on COMSOL 5.0 of reduced size micro-gripper for micro-robotics and micro-surgery field application. The performance of this proposed reduced size design of bi-morph electro-thermic actuated micro-gripper is optimized in terms of material optimization as well as dimensional optimization because these are the greatly affecting factors. The investigated results show very good agreement with the electro-thermal actuation operating mechanism. During simulation we limit operating voltage range from 0 to 2 volts.

Extended elliptic-type integrals with associated properties and Turán-type inequalities

Abstract: Our aim is to study and investigate the family of $(p, q)$ -extended (incomplete and complete) elliptic-type integrals for which the usual properties and representations of various known results of the (classical) elliptic integrals are extended in a simple manner. This family of elliptic-type integrals involves a number of special cases and has a connection with $(p, q)$ -extended Gauss’ hypergeometric function and $(p, q)$ -extended Appell’s double hypergeometric function $F_{1}$ . Turan-type inequalities including log-convexity properties are proved for these $(p, q)$ -extended complete elliptic-type integrals. Further, we establish various Mellin transform formulas and obtain certain infinite series representations containing Laguerre polynomials. We also obtain some relationship between these $(p, q)$ -extended elliptic-type integrals and Meijer G-function of two variables. Moreover, we obtain several connections with $(p, q)$ -extended beta function as special values and deduce numerous differential and integral formulas. In conclusion, we introduce $(p, q)$ -extension of the Epstein–Hubbell (E-H) elliptic-type integral.

Solar PV based grid interfaced system with power quality improvement

Abstract: Above paper present the development of Solar PV based system with grid interfacing involving power quality improvement measures by using a L-C filter. And a three-phase voltage source converter is used in place of an inverter for interfacing between the DC-Voltage produced by solar and the grid having AC-transmission line. A MPPT technique is also used in this system to enhance the efficiency of the PV array irrespective of the variable climatic conditions. So that maximum power could be extracted from the solar PV array and connected to the grid.

Mixed Method Application in Order Reduction of Discrete System

Abstract: In this manuscript model order reduction of the higher order discrete time state space model is done. The mode selection method and Continued Fraction Cauer second form is being used. The numerator part is derived by mode selection method and denominator part is calculated by Continued Fraction Cauer Second Form. The method is applied in a fourth order discrete time transfer function. The obtained lower order is compared with the original discrete time higher order system and second order reduced transfer function available in literature. The comparison of characteristics plot of the original transfer function with second order proposed and reduced order available in literature is done by the step response and pole zero mapping.
