“The physiologic capabilities of the heart are enormous, and in judging the effect of any undue exertion on it, we must not regard the murmurs of the irregularity alone, but must also consider carefully, the way in which the heart is doing its work, its strength, as shown by its ability to maintain proper arterial tension, and its recuperative power. As with other muscles, not size but quality ...

Motion and intrusion detection are often cited as wireless sensor network (WSN) applications with typical configurations comprising clusters of wireless nodes equipped with motion sensors to detect human motion. Currently, WSN performance is subjected to several constraints, namely radio irregularity and finite on-board computation/energy resources. Radio irregularity in radio frequency (RF) pr...

In reality, radio range of any wireless communication device does not emulate an isotropic behavior or as modeled by theory. An isotropic antenna is a hypothetical lossless antenna having equal energy being radiated or transmitted in all directions. Along with wireless sensor networks, any wireless network suffered propagation complications including multipath propagation, shadowing and path lo...

Motion and intrusion detection are often cited among various Wireless Sensor Network (WSN) applications. A typical configuration comprises clusters of wireless nodes equipped with motion sensors to detect human motion. Currently, the performance of WSN is subject to several constraints, mainly the phenomenon of radio irregularity and finite onboard computation/energy resources. In Radio Frequen...

Let R be a commutative ring and Z(R) the set of all zero divisors R. Γ(R) is said to divisor graph if x,y ∈ V (Γ(R)) = (x,y) E(Γ(R)) only x.y 0. In this paper, we determine total vertex irregularity strength graphs associated with rings ℤp2 × Zq for p,q prime numbers.

Let G be a simple graph of n order. An edge labeling such that the weights all vertex are different and elements set modulo n, called modular irregular labeling. The irregularity strength is minimum positive integer k have If none, then we infinity. In this article, determine complete graphs.

Abstract Cement sheath is an annular structure situated between casing and formation, which designed to seal the formation reinforce borehole. However, owing surface irregularity drilling mud residue, interface cement one of weakest parts for fluid leakage causing well integrity issues, would also affect reliability bond logs. To evaluate cementation state tensile properties cement-formation in...
