Modulation of non-linear waves in a viscous fluid contained in an elastic tube
(Pergamon-Elsevier Science, 2001-06)
In the present work, utilizing the non-linear equations of a prestressed thin elastic tube filled with an incompressible viscous fluid the propagation of weakly non-linear waves in such a medium is studied. Considering ...
Solitary waves in fluid-filled elastic tubes: weakly dispersive case
(Pergamon-Elsevier Science, 2001-03)
In the present work, employing the nonlinear equations of an incompressible, isotropic and elastic thin tube and the approximate equations of an incompressible inviscid fluid, the propagation of weakly nonlinear waves, in ...
Solitary waves in elastic tubes filled with a layered fluid
(Pergamon-Elsevier Science, 2001-04)
In this work, we studied the propagation of weakly non-linear waves in a prestressed thin elastic tube filled with an incompressible layered fluid, where the outer layer is assumed to be inviscid whereas the cylindrical ...
Strategies for the evolution of sex
(American Physical Soc, One Physics Ellipse, 2001-12)
We find that the hypothesis made by Jan, Stauffer, and Moseley [Theory Biosci. 119, 166 (2000)] for the evolution of sex, namely, a strategy devised to escape extinction due to too many deleterious mutations, is sufficient ...
Interactions of nonlinear acoustic waves in a fluid-filled elastic tube
(Pergamon-Elsevier Science, 2001-03)
In the present work, the nonlinear interactions of two acoustical waves propagating in a fluid-filled elastic tube with different wave numbers, frequencies and group velocities are examined. Employing the multiple-scale ...
Effect of annealing temperature on determining trap depths of quartz by various heating rates method
(Pergamon-Elsevier Science, 2001-12)
The aim of this study is to determine the trap parameters (trap depth E, frequency factors) of quartz using various heating rates method and also to investigate the effect of annealing temperature on determining trap depths. ...
Localized travelling waves in a prestressed thick elastic tube
(Pergamon-Elsevier Science, 2001-10)
In the present work, by using the exact non-linear equations of an incompressible inviscid fluid contained in a prestressed thick elastic tube, the propagation of localized travelling wave solution in such a medium is ...
Evolutionary route to diploidy and sex
(National Academy of Sciences, 2001-11-20)
By using a bit-string model of evolution, we find a successful route to diploidy and sex in simple organisms. Allowing the sexually reproducing diploid individuals to also perform mitosis, as they do in a haploid-diploid ...
Nonlinear waves in a viscous fluid contained in a viscoelastic tube
(Birkhauser Verlag, 2001-11)
In the present work the propagation of weakly nonlinear waves in a prestressed viscoelastic thin tube filled with a viscous fluid is studied. Using the reductive perturbation technique in analyzing the nonlinear equations ...
Strategies for the evolution of sex
(American Institute of Physics Inc., 2001-12)
The maintenance of a macroscopic sexual population is addressed. As a scenario, the mechanism of random conversion to sex, in the presence of a constant rate of mutation is examined. This scenario is very closely related ...
