This study is concerned to check the validity and applicability of a five parameter viscoelastic model for harmonic wave propagating in the non-homogeneous viscoelastic rods of varying density. The constitutive relation for five parameter model is first developed and validity of these relations is checked. The non-homogeneous viscoelastic rods are assumed to be initially unstressed and at rest....

We give sufficient conditions for the tautness of a transversely homogenous foliation defined on compact manifold, by computing its base-like cohomology. As an application, we prove that if is non-unimodular then either ambient closure leaves or total space associated principal bundle fiber over S 1 .

A more realistic way to describe a model is the use of intervals which contain required values parameters. In practice we estimate parameters from set data and it natural that they will be in confidence intervals. present study, study Non-Homogeneous Markov Systems (NHMS) processes for basic are We call such Set (NHMSS). First relative expected population structure memberships prove under certa...
