Analysis on catastrophe effect of political risk diffusion on multinational oil and gas pipelines

open access: yesYou-qi chuyun, 2021
With more energy imported by China, the business on construction and operation of multinational oil and gas pipelines is increasing rapidly. The unique political attributes of multinational oil and gas pipelines are likely to bring about complicated and ...

Theory of a Slow-Light Catastrophe [PDF]

open access: yes, 2001
In diffraction catastrophes such as the rainbow the wave nature of light resolves ray singularities and draws delicate interference patterns. In quantum catastrophes such as the black hole the quantum nature of light resolves wave singularities and ...

Gradient catastrophe and flutter in vortex filament dynamics

open access: yes, 2011
Gradient catastrophe and flutter instability in the motion of vortex filament within the localized induction approximation are analyzed. It is shown that the origin if this phenomenon is in the gradient catastrophe for the dispersionless Da Rios system ...

Bistability and instability of dark-antidark solitons in the cubic-quintic nonlinear Schroedinger equation [PDF]

open access: yes, 2011
We characterize the full family of soliton solutions sitting over a background plane wave and ruled by the cubic-quintic nonlinear Schroedinger equation in the regime where a quintic focusing term represents a saturation of the cubic defocusing ...

Multi-attribute decision-making method with triangular fuzzy numbers based on regret theory and the catastrophe progression method

open access: yesMathematical Biosciences and Engineering, 2022
The purpose of this paper was to develop a novel triangular fuzzy method for multi-attribute decision-making to eliminate the influence of indicator weights on scheme selection and account for the regret psychology of decision-makers.
