چکیده
Radio antennas switch signals in the form of radio waves using different frequency bands electromagnetic spectrum. To avoid interruption, each station is assigned a unique number. The channel assignment problem refers to this application. A geometric mean labeling connected graph G an injective function h from vertex set, V(G) set natural numbers N such that for any two distinct vertices x and y G, h(x)·h(y)≥diam+1−d(x,y). number h, rgmn(h), maximum G. rgmn(G) minimum value taken over all In paper, we present theorems calculating exact paths cycles. We also novel algorithm determining upper bound given graph. verify bounds obtained coincide with paths, cycles, stars, bi-stars.

A Novel Multicast Tree Construction Algorithm for Multi-Radio Multi-Channel Wireless Mesh Networks
Many appealing multicast services such as on-demand TV, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. When multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. Designing a good multicast tree to route data packets could enhance the...
متن کاملA Novel Algorithm for Digital Distance Relaying
Distance relays are used to protect EHV and HV Transmission lines. Over the past decades many algorithms have emerged for digital distance relays. These are based on the calculation of the transmission line impedance from the relaying to fault points. In this paper a novel method for digital distance relaying is proposed. In the method the tracking procedure is implemented. The method uses the ...

متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
The geometric mean algorithm
Bisection (of a real interval) is a well known algorithm to compute eigenvalues of symmetric matrices. Given an initial interval [a, b], convergence to an eigenvalue which has size much smaller than a or b may be made considerably faster if one replaces the usual arithmetic mean (of the end points of the current interval) with the geometric mean. Exploring this idea, we have implemented geometr...
