the microscopic and geomechanical properties of igneous building stones include the level of alteration, presence of micro cracks, peak strength, porosity, proportion of detrimental minerals, etc. porosity is reportedly of a devastating impact on the peak strength of igneous rocks. the quartz diorite rock samples in this study were selected from five quarries in natanz, iran and subject to micr...

We suggest that all horizons of spacetime, no matter whether they are black hole, Rindler, or de Sitter horizons, have certain microscopic properties in common. We propose that these properties may be used as the starting points, or postulates, of a microscopic theory of gravity. ∗ e-mail: [email protected]

Given that quantum theory is probabilistic, is there a fundamental physical principle that dictates the form of the quantum probability law? We will argue that, indeed, the assigned probabilities for a given test performed on a large sample of identical systems are dictated by the classical-like properties of macroscopic systems. Consider a sample of N identically prepared nonentangled spins in...

Aharonov and Reznik have recently argued that the form of the probabilistic predictions of quantum theory can be seen to follow from properties of macroscopic systems. An error in their argument is identified .

In this paper a new macroscopic k-ε model is developed and validated for turbulent flow through porous media for a wide range of porosities. The morphology of porous media is simulated by a periodic array of square cylinders. In the first step, calculations based on microscopic v2 − f model are conducted using a Galerkin/Least-Squares finite element formulation, employing equalorder bilinear ve...
