Inclusion of matter in inhomogeneous loop quantum cosmology [PDF]

AIP Conference Proceedings, 2012
We study the hybrid quantization of the linearly polarized Gowdy $T^3$ model with a massless scalar field with the same symmetries as the metric. For simplicity, we quantize its restriction to the model with local rotational symmetry.

Seismic wave reflection characteristics and wave-induced fluid flow in unsaturated porous solid [PDF]

Scientific Reports
This study examines the characteristics of seismic wave reflection and wave-induced fluid flow (WIFF) in an unsaturated porous solid half-space confined beneath an impermeable plane surface. We first present the field equations and constitutive relations

The Fundamental Formulation for Inhomogeneous Inclusion Problems with the Equivalent Eigenstrain Principle

Metals, 2022
In this paper, and on the basis of the equivalent eigenstrain principle, a fundamental formulation for inhomogeneous inclusion problems is proposed, which is to transform the inhomogeneous inclusion problems into auxiliary equivalent homogenous inclusion

Variational Approach to Modeling of Curvilinear Thin Inclusions with Rough Boundaries in Elastic Bodies: Case of a Rod-Type Inclusion

Mathematics, 2023
In the framework of 2D-elasticity, an equilibrium problem for an inhomogeneous body with a curvilinear inclusion located strictly inside the body is considered. The elastic properties of the inclusion are assumed to depend on a small positive parameter δ
