Optimal reactive power flow is an optimization problem with one or more objective of minimizing the active power losses for fixed generation schedule. The control variables are generator bus voltages, transformer tap settings and reactive power output of the compensating devices placed on different bus bars. BiogeographyBased Optimization (BBO) technique has been applied to solve different kind...

The main part of the magnetic fluxgate sensor is the magnetic core, the hysteresis characteristic of which affects the performance of the sensor. When the fluxgate sensors are modelled for design purposes, an accurate model of hysteresis characteristic of the cores is necessary to achieve good agreement between modelled and experimental data. The Jiles-Atherton model is simple and can reflect t...

Orthodontic preparation for surgical treatment of skeletal Class III malocclusion involves joint planning with an oral and maxillofacial surgeon to address the functional and esthetic needs of the patient. In order to allow surgical manipulation of the jaws in the preoperative phase, the need to achieve a negative overjet through incisor decompensation often leads the orthodontist to extract th...

Biogeography is the study of distribution of biological species, over space and time, among random habitats. Recently developed Biogeography-Based Optimization (BBO) is a technique, where solutions of the problem under consideration are named as habitats; similar to chromosome in Genetic Algorithms (GAs) and particles in Particle Swarm Optimization (PSO). Feature sharing among various habitats,...

P. ARAVINDHABABU Professor of Electrical Engineering, Annamalai University, Annamalainagar-608002, Tamil Nadu, India [email protected] Abstract The dynamic economic emission dispatch (DEED) presumes a lot of significance to meet the clean energy requirements of the society and simultaneously minimizes the cost of generation. The biogeography based optimization (BBO), inspired from...

The recent discovery of two-dimensional (2D) superconductivity at the interface $\mathrm{Ba}\mathrm{Pb}{\mathrm{O}}_{3}$ (BPO) and $\mathrm{Ba}\mathrm{Bi}{\mathrm{O}}_{3}$ (BBO) has motivated us to study in depth electronic structural properties relation between them this particular heterostructure, by means first-principles calculations. Our results indicate that breathing distortions, charge ...

In this work, the dispersive shock wave (DSW) solution of a Boussinesq Benjamin–Ono (BBO) equation, standard equation with dispersion replaced by nonlocal dispersion, is derived. This DSW derived using two methods, fitting and from simple Whitham modulation equations for BBO equation. The first these yields edges DSW, while second complete solution. As could not be set in Riemann invariant form...
