(Preliminary Report.) The model formulation and existence theory is described for diffusion of a barotropic fluid through a partially saturated poroelastic composite medium consisting of two components. This includes the Barenblatt-Biot doublediffusion model of elastic deformation and laminar flow in a fissured medium, such as consolidation processes in a system of fissures distributed througho...

Comparisons between predictions of a Biot-Allard model allowing for angle-dependent elasticity and angle-and-porosity dependent tortuosity and transmission data obtained at normal incidence on water-saturated replica bones are extended to oblique incidence. The model includes two parameters which are adjusted for best fit at normal incidence. Using the same parameter values, it is found that pr...

In this paper, natural frequencies and dynamic response of thick beams made of saturated porous materials resting on viscoelastic foundation are investigated for the first time. The beam is modeled using higher-order beam theory. Kelvin-voight model is used to model the viscoelastic foundation. Distribution of porosity along the thickness is considered in two different patterns, which are symme...

This article investigates the influence of cross-diffusion on the viscous fluid flow over a porous sheet stretching exponentially by applying the convective thermal conditions. Velocity slip at the boundary is considered. The numerical solutions to the governing equations are evaluated using successive linearisation procedure and Chebyshev collocation method. It is observed from this study that...

A new technology known as the internet of things (IoT) allows both physical and virtual items to be linked communicated with one another, creating digital services that enhance our fineness sustenance. The IoT system has a number benefits, but because its present centralized architecture, there are several problems regard data integrity, security, privacy, single points failure. future developm...

In the article number 2200357 Tomonaga Ueno, and co-workers report an ultralight single-walled carbon nanotube (SWCNT) aerogel for low-frequency sound absorption, with a hierarchical porous structure high-modulus framework. The Biot–Johnson–Champoux–Allard model indicates significant effect of high elastic modulus SWCNT on absorption.

In order for auralization to better replicate the binaural listening experience in a space, acoustic scattering in the room impulse response (RIR) must be more accurately calculated. Three models are discussed and used in room computations and auralizations: Lambert scattering, edge-diffraction models based on the Biot-Tolstoy-Medwin technique, and boss models for protuberances on reflecting su...

Stoneley waves in permeable boreholes are diagnostic of formation permeability because their propagation is affected by the dynamic fluid flow at the borehole wall. We characterize this flow using the concept of dynamic permeability. We examined the applicability of the dynamic permeability to porous media by applying it to a single fracture case and found that it agrees excellently with the fr...

Purpose Due to the rapid growth of blockchain technology in recent years, fusion and Internet Things (BIoT) has drawn considerable attention from researchers industrial practitioners is regarded as a future trend technological development. Although several authors have conducted literature reviews on topic, none examined development knowledge structure BIoT, resulting scattered research (R&...
