Coherent structures and turbulence
Journal of Fluid Mechanics, 1986This is a personal statement on the present state of understanding of coherent structures, in particular their spatial details and dynamical significance. The characteristic measures of coherent structures are discussed, emphasizing coherent vorticity as the crucial property.

Structural Coherence Mathematics
Structural Coherence Mathematics (SCM) is a symbolic framework that reconstructs physics, identity, and cosmology from a single ontological principle: return. In SCM, an identity persists only if it returns — coherence is not assumed; it is structurally defined.openaire +1 more source
Visualization of Coherent Structures
1994The visualization of coherent structures is illustrated in two-dimensional flows as rotating and stratified fluids. The visualization is based on the development of dye concentration for measurements of the gross properties of the structures, and on a particle tracking method, which provides detailed knowledge of the flow field.

Coherent Structures in Plasmas
1984Both laboratory and cosmic plasmas are extremely non-equilibrium media. This fact is especially evident for laboratory plasmas, since the ionized gas cannot be in equilibrium with the cold walls of a vessel in which plasma is sustained. (We do not consider here the case of a weakly ionized thermal gas within a hot-walled vessel).

Rationality: Coherence and Structure
2000In this paper, it is argued that the standard decision theoretic axioms provide core principles action-guiding preferences of rational agents should be required to satisfy. This, however, does not involve a commitment to consequentialism.
