Acoustics of fractal porous material and fractional calculus
(MDPI, 2021)In this paper, we present a fractal (self-similar) model of acoustic propagation in a porous material with a rigid structure. The fractal medium is modeled as a continuous medium of non-integer spatial dimension. The basic ... -
Transient Propagation of Longitudinal and Transverse Waves in Cancellous Bone: Application of Biot Theory and Fractional Calculus
(MDPI, 2022)In this paper, the influence of the transverse wave on sound propagation in a porous medium with a flexible structure is considered. The study is carried out in the time domain using the modified Biot theory obtained by ... -
Flow of a Self-Similar Non-Newtonian Fluid Using Fractal Dimensions
(MDPI, 2022)In this paper, the study of the fully developed flow of a self-similar (fractal) power-law fluid is presented. The rheological way of behaving of the fluid is modeled utilizing the Ostwald–de Waele relationship (covering ... -
On atomic state purity operator, degree of state purity and concurrence in the JC and anti-JC models
(arxiv.org, 2022)The state of an atom in a bipartite qubit, Jaynes-Cummings (JC) or anti-Jaynes-Cummings (aJC) interaction is described by a reduced density operator. The purity of the state has been measured by taking the trace of the ... -
Analysis of the impact of domestication of Warburgia ugandensis (Sprague) on its genetic diversity based on amplified fragment length polymorphism
(African Journal of Biotechnology, 2016)Warburgia ugandensis Sprague (Canellaceae) occurs in East and Central Africa and is an important multipurpose tree species. Over-exploitation of natural forests for medicinal purposes and clearance for farming threaten the ... -
