The aim of this work is to design and simulate an armature and field control systems using state feedback controller based on bacterial foraging optimization (BFO) technique for controlling the speed of separately excited dc motor (SEDM). The controller's performances have been optimized based on social foraging behavior of Escherichia (E. Coli) bacteria. The state feedback controller's paramet...

Magnetoelectric multiferroic BiFeO3 (BFO) was synthesized by a simple carbonate precipitation technique of metal nitrate solutions. X-ray powder diffraction and thermo-gravimetric analysis (TGA) revealed that the precipitate consists of an intimate mixture of crystalline bismuth carbonate and an amorphous hydroxide of iron. The precipitate yielded BiFeO3 at an optimal calcination temperature of...

In this paper, Stochastic Economic Load Dispatch problem with Multiple Fuels is solved using Pareto distribution with local convex optimization by bacterial foraging approach. Bacterial foraging optimization is swarmed intelligence technique used to solve the problem of the power system. The algorithm is based on the group foraging behavior of Escherichia coli (E-coli) bacteria present in the h...

The rapid increase of digitized media because of the proliferation of networked multimedia has created many issues like related to copyright protection, easily copying and transmitting the digital data. This has created the need for various techniques which helps to protect the digital media over the internet. Digital watermarking is one of the solutions. Digital watermarking is a technique whi...

Abstract Cobalt-free perovskite oxide BaFeo 3-δ (BFO) exists in mixtures with various phase structures and exhibits poor oxygen ion conductivity, thereby limiting its application as a cathode material solid fuel cells (SOFC). In this study, the stabilization of single cubic structure BFO through doping Gd at A-site or Cu B-site lowest temperature required for synthesis such are investigated. A ...

We elucidated a number of facets regarding glutathione (GSH)-bismuth ferrite (BiFeO3, BFO) interactions and reactivity that have previously remained unexplored on a molecular level. In this approach, the cation-modified reduced GSH (or oxidised glutathione (GS·)) formed on the (111)-oriented BiFeO3 membrane (namely BFO-(111)) can serve as an efficient quencher, and the luminescence mechanism is...

To find the optimal path by interacting with multiple robots is the main research area in field of robotics. The task is to find the global optimal path with a minimum amount of computation time. Path planning has numerous application like industrial robotics, to design autonomous system etc. In this paper, we survey on three most recent algorithms namely Bacteria forging Optimization (BFO), An...

Segmentation partitions an image into its constituent parts. It is essentially the pre-processing stage of image analysis and computer vision. In this work, T1 and T2 weighted brain magnetic resonance images are segmented using multilevel thresholding and bacterial foraging optimization (BFO) algorithm. The thresholds are obtained by maximizing the between class variance (multilevel Otsu method...

Science aims to develop an accurate understanding of reality through a variety of rigorously empirical and formal methods. Ontologies are used to formalize the meaning of terms within a domain of discourse. The Basic Formal Ontology (BFO) is an ontology of particular importance in the biomedical domains, where it provides the top-level for numerous ontologies, including those admitted as part o...

Bacterial Foraging Optimization Technique is used in optimization for grid computing as they get their inspirations from evolutionary idea of natural evolution. It has been broadly accepted as a global optimization algorithm of current interest for distributed optimization and control. This algorithm is inspired by the social foraging behavior of Escherichia coli. Bacterial Foraging Optimizatio...
