Geochemical Phase Diagrams and Gale Diagrams
The problem of predicting the possible topologies of a geochemical phase diagram, based on the chemical formula of the phases involved, is shown to be intimately connected with and aided by well-studied notions in discrete geometry: Gale diagrams, triangulations, secondary fans, and oriented matroids.
متن کاملImprobable Creativity
We begin with a number of basic facts about creativity and a brief history of the idea. These provide criteria that any definition of the term should meet and help guide us to a new definition of creativity. This definition is independent of cultural appropriateness or the perceived value of creative objects, ideas which have encumbered previous investigations. We briefly defend our definition ...
متن کاملStability of a thermodynamically coherent multi-phase model
We analyze a hyperbolic system of conservation laws in dimension one, which is a drastic simplification of a multi-phase or multi-velocity fluid model. The domain of hyperbolicity is compact, which is a characteristic of multi-phase models. Our main result is the stability of the domain of hyperbolicity. Due to the degeneracy of the model on the boundary of the hyperbolicity domain, rarefaction...
متن کاملIce XV: a new thermodynamically stable phase of ice.
A new phase of ice, named ice XV, has been identified and its structure determined by neutron diffraction. Ice XV is the hydrogen-ordered counterpart of ice VI and is thermodynamically stable at temperatures below approximately 130 K in the 0.8 to 1.5 GPa pressure range. The regions of stability in the medium pressure range of the phase diagram have thus been finally mapped, with only hydrogen-...
متن کاملOn thermodynamically consistent schemes for phase field equations
This paper addresses the issue of thermodynamically consistent derivations of field equations governing nonisothermal processes with diffuse interfaces and their implications for interface conditions in the associated sharp interface theories. We operate within the framework of extended irreversible thermodynamics, allowing gradient terms to be present not only in the free energy and entropy de...
