Weakly non-linear waves in a tapered elastic tube filled with an inviscid fluid
(Pergamon-Elsevier Science Ltd, 2005-07)
In the present work, treating the artery as a tapered, thin walled, long and circularly conical prestressed elastic tube and using the longwave approximation, we have studied the propagation of weakly non-linear waves in ...
Small molecule desorption prior to dissolution of a polymeric glass
(Wiley Subscription Services, Inc., A Wiley Company, 2006-07-15)
Poly(methyl methacrylate) (PMMA) discs in various molecular weights (M-w) were prepared by free-radical polymerization. Pyrene (Py) was introduced during polymerization as a fluorescence probe. In situ steady state ...
Two remarks on a generalized Davey-Stewartson system
(Elsevier Ltd, 2006-03-01)
We present two results on a generalized Davey-Stewartson system, both following from the pseudo-conformal invariance of its solutions. In the hyperbolic-elliptic-elliptic case, under some conditions on the physical parameters, ...
Quarantine region scheme to mitigate spam attacks in wireless sensor networks
(IEEE, 2006-08)
The Quarantine Region Scheme (QRS) is introduced to defend against spam attacks in wireless sensor networks where malicious antinodes frequently generate dummy spam messages to be relayed toward the sink. The aim of the ...
The sectoral sweeper scheme for wireless sensor networks: Adaptive antenna array based sensor node management and location estimation
(Kluwer Academic Publishers-Plenum Publishers, 2006-12)
We introduce a novel sensor node management and location estimation method referred as sectoral sweeper (SS) scheme that uses an adaptive antenna array (AAA) at a central node in wireless sensor networks (WSNs). With the ...
The conformal Penrose limit and the resolution of the pp-curvature singularities
(IOP Publishing, 2006-01-21)
We consider the exact solutions of the supergravity theories in various dimensions in which the spacetime has the form M-d x SD-d where M-d is an Einstein space admitting a conformal Killing vector and SD-d is a sphere of ...
Reordering of polystyrene gel due to multiple swelling in organic vapor fast transient fluorescence technique study
(Elsevier Science SA, 2006-07-31)
Reordering of disc-shaped polystyrene (PS) gels due to multiple swelling, under organic vapor was studied by using Fast Transient Fluorescence (FTRF) technique. Disc-sbaped polystyrene gels were prepared by free radical ...
Reflection and transmission of nonlinear waves from arterial branching
(Elsevier Ltd, 2006-10)
In this work, treating the arteries as a prestressed thin walled elastic tube and the blood as an inviscid fluid, we have studied the reflection and transmission of nonlinear waves from arterial branching, through the use ...
Phase transitions of kappa-carrageenan gels in various types of salts
(John Wiley & Sons Inc, 2006-11-05)
Sol-gel and gel-sol phase transitions of K-carrageenan in various types of salts were studied using photon transmission technique. Here, LiCl, NaCl, KCl, MgCl2, CaCl2, and SrCl2 were chosen as the proper salts for the ...
Equivalent dose in quartz from young samples using the SAR protocol and the effect of preheat temperature
(Pergamon-Elsevier Science Ltd, 2006-09)
Major concerns in the dating of samples younger than a few hundred years by the optically stimulated luminescence (OSL) technique are thermal transfer and partial bleaching. Thermal transfer during preheating enhances the ...
