In physics and cosmology, digital physics is a collection of theoretical perspectives based on the premise that the universe is describable by information is a form of digital ontology about the physical reality. According to this theory, the universe can be conceived of as either the output of a deterministic or probabilistic computer program, a vast, digital computation device, or

The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond (1958) or Azzaroni (1984) or by using special batchgrinding tests interpreted in the content of population balance models (Lo and Herbst 1986).

May 06, 2019 · What''s more, maths can''t be the "mirror" of anything in nature if the two are identical in the first place. In other words, any mathematical models which are said to "perfectly capture nature" (or causality) can only do so because nature (or causality) is already mathematical. If that weren''t the case, then no perfect modelling (or perfectly precise equations) could exist.
Background Nurses working in hospital environments are at risk for burnout. Exposure to nature has psychological benefits, but the effect of hospital gardens on nurse burnout is less understood. Objective To compare the effect on nurse burnout of taking daily work breaks in a hospitalintegrated garden with the effect of indooronly breaks.

Fluid (gas and liquid) ﬂows are governed by partial diﬀerential equations which represent conservation laws for the mass, momentum, and energy. Computational Fluid Dynamics (CFD) is the art of replacing such PDE systems by a set of algebraic equations which can be solved using digital computers.
This paper presents comparisons between recently proposed PartiallyAveraged NavierStokes (PANS) method with the Large Eddy Simulation (LES) for the flow around the Ahmed bluff body. PANS model changes seamlessly from Reynolds Averaged NavierStokes (RANS) to the direct numerical solution of the NavierStokes equations (DNS) as the unresolvedtototal ratios of kinetic energy and dissipation

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
