Empirical study of the Bee Colony Optimization (BCO) algorithm

Expert Systems With Applications, 2013
The Bee Colony Optimization (BCO) meta-heuristic deals with combinatorial optimization problems. It is biologically inspired method that explores collective intelligence applied by the honey bees during nectar collecting process. In this paper we perform empirical study of the BCO algorithm.

Processing and properties of large grain (RE)BCO

Materials Science and Engineering B: Solid-State Materials for Advanced Technology, 1998
Abstract The potential of high temperature superconductors to generate large magnetic fields and to carry current with low power dissipation at 77 K is particularly attractive for a variety of permanent magnet applications. As a result large grain bulk (RE)-Ba-Cu-O ((RE)BCO) materials have been developed by melt process techniques in an attempt to ...

Reaction of boron atoms with carbon monoxide: matrix infrared spectra of BCO, (BCO)2, and B(CO)2

The Journal of Physical Chemistry, 1992
Infrared spectra were obtained for Ar/CO samples codeposited with laser ablated boron atoms on a 12±1 K salt window. BCO was identified as the primary reaction product, based on isotropic substitution at all atomic positions and ab initio structure and frequency calculations.

Developments in the processing of bulk (RE)BCO superconductors

Physica C: Superconductivity, 2011
The development of a practical processing method for the fabrication of high performance large, single grain bulk superconductors is essential for their cost-effective application in a variety of high field engineering devices. We discuss recent developments in the processing of these materials that enable high performance bulk superconductors to be ...

Growth Rate and Superconductivity of Y(Sm)BCO Single Crystals

Physica C: Superconductivity, 1996
Abstract A series of Y 1− x Sm x Ba 2 O 6+δ [Y(Sm)BCO] single crystals were grown by the crystal pulling method. By substitution of Sm for Y, the growth rate was obviously increased, it was nearly 2 times higher with a Sm content x of 0.119 than that of YBCO.

Novel methods to characterize bulk RE-BCO superconductors

Physica C: Superconductivity, 2005
Abstract We report on new techniques for the investigation of the radial and the axial homogeneity of top seeded melt-textured RE–Ba–Cu–O (REBCO) monoliths. Whereas the traditional Hall probe scanning technique of trapped fields at the surface of the superconductor provides only global information on the patterns of supercurrent flow, a modified ...

EBSD Characterization of Specific Microstructures in RE-BCO Superconductors

IEEE Transactions on Applied Superconductivity, 2019
Using the electron backscatter diffraction (EBSD) technique, we analyze in this contribution the microstructure of YBa2Cu3O x (YBCO) thick films with embedded a -axis oriented grains. The YBCO films were prepared by liquid phase epitaxy in air using NdGaO3 substrates.

Bee Colony Optimization (BCO)

2009
Swarm Intelligence is the part of Artificial Intelligence based on study of actions of individuals in various decentralized systems. The Bee Colony Optimization (BCO) metaheuristic has been introduced fairly recently as a new direction in the field of Swarm Intelligence.

Structural study of commercially produced (RE)BCO films

IEEE Transactions on Applied Superconductivity, 2016
Various deposition techniques used in the coated conductor industry result in the formation of different structural inhomogeneities within the superconducting film, having an impact on its electromagnetic properties. In this paper, an attempt for complex characterization of the Y(Gd)Ba 2 Cu 3 O 7-x [(RE)BCO] structure in tapes from two major producers
