WorldAmong environmental sociologists, ecological Marxists argue that there is an association between capitalism and ecological destruction/disorganization. This argument suggests that capitalism and nature are in contradiction with one another, so that the ...

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Analytic mode matching for a circular dissipative silencer containing mean flow and a perforated pipe [PDF]
, 2007 An analytic mode matching scheme that includes higher order modes is developed for a straight-through circular dissipative silencer. Uniform mean flow is added to the central airway and a concentric perforated screen separates the mean flow from a bulk ...

Dissipative Structures in Supersonic Turbulence
Physical Review Letters, 2009 We show that density-weighted moments of the dissipation rate, $ε_l$, averaged over a scale $l$, in supersonic turbulence can be successfully explained by the She and Lévêque model [Phys. Rev. Lett. {\bf 72}, 336 (1994)]. A general method is developed to measure the two parameters of the model, $γ$ and $d$, based directly on their physical ...

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Model reduction of dissipative systems by balanced truncation
, 2008 Given a dissipative system behavior with general supply rate, say a ?Sigma-dissipative system, we propose a balanced truncation method to obtain a reduced-order system behavior which is again ?Sigma-dissipative.

Self Organization Analysis of Soil Erosion
Shuitu baochi yanjiu, 2007 The dissipative structure about soil erosion was analyzed by using the theory of dissipative structure,and a model about soil erosion organization’s form was established.The authors analyzed three soil and water conservation measures: biological measures,

A Drive towards Thermodynamic Efficiency for Dissipative Structures in Chemical Reaction Networks
Entropy, 2021 Dissipative accounts of structure formation show that the self-organisation of complex structures is thermodynamically favoured, whenever these structures dissipate free energy that could not be accessed otherwise.
