The crowding of wireless band has necessitated the development of multiband and wideband wireless antennas. Because of the self similar characteristics, fractal concepts have emerged as a design methodology for compact multiband antennas. A Koch-like fractal curve is proposed to transform ultra-wideband (UWB) bow-tie into so called Koch-like sided fractal bow-tie dipole. A small isosceles trian...

OBJECTIVES The purpose of this study was to characterize anisotropy in the triangle of Koch by relating electrophysiology with anatomy. BACKGROUND Atrioventricular (AV) node fast and slow pathway characteristics have been suggested to be due to nonuniform anisotropy in the triangle of Koch. METHODS During atrial pacing, we determined the electrical activity within the triangle of Koch by mu...

The antimicrobial activity of the methanol extracts of the dried flowering aerial parts of Stachys byzantina, S. inflata, S. lavandulifolia and S. laxa (Labiatae) were studied using the disc diffusion method and determination of minimum inhibitory concentration (MIC) values against Staphylococcus aureus, Streptococcus sanguis, Escherichia coli, Pseudomonas aeroginosa, Klebsiella pneumoniae, Asp...

Preparative reversed-phase HPLC analysis of the methanol extract of the aerial parts of Stachys bombycina (Lamiaceae) afforded two acylated flavonoids glycosides, chrysoeriol 7-O-[6-O-acetyl-beta-D-allopyranosyl]-(1 --> 2)-beta-D-glucopyranoside (1) and apigenin 7-O-beta-D-(6-p-coumaroyl)-glucopyranoside (2), the former being a new natural product. The structures of these compounds were elucida...

Fractal objects have some unique geometrical properties. One of them is the possibility to enclose in a finite area an infinitely long curve. The resulting curve is highly convoluted being nowhere differentiable. One such curve is the Koch curve. In this paper, the behavior the Koch monopole is numerically and experimentally analyzed. The results show that as the number of iterations on the sma...

Real-world systems in nature can be described by complex networks. It is of current interest for researchers to construct network models depicting complex systems. In this paper, the generalized Koch network is proposed, which exhibits some properties of Koch networks. Analytical expressions involving the degree distribution, clustering coefficient and average path length for the generalized Ko...
