A cusp catastrophe model for alluvial channel stability

Shui kexue jinzhan, 2012
The self-adjustment of an alluvial channel is a complicated process with various factors influencing the stability and transformation of channel patterns.Although the formation of alluvial channels has been extensively studied,the problem of the alluvial

Disentangling phase transitions and critical points in the proton–neutron interacting boson model by catastrophe theory

Physics Letters B, 2014
We introduce the basic concepts of catastrophe theory needed to derive analytically the phase diagram of the proton–neutron interacting boson model (IBM-2). Previous studies [1–3] were based on numerical solutions.

Catastrophe models and the expansion method: A review of issues and an application to the econometric modeling of economic growth

Discrete Dynamics in Nature and Society, 1997
Many negative reactions to Catastrophe Theory have been triggered by overly simplistic applications unintended and unsuited for statistical-econometric estimation, inference, and testing.

Mechanism for the formation of the high-altitude stagnant cusp: Cluster and SuperDARN observations [PDF]

, 2006
On 16 March 2002, Cluster moved from nightside to dayside, across the high-altitude northern cusp during an extended period of relatively steady positive IMF BY and BZ. Combined Cluster and SuperDARN data imply the existence of two reconnection sites: in

Investigating Stock Market Crashes Using Cusp Model: A Study on Tehran Stock Exchange [PDF]

Faslnāmah-i Pizhūhish/Nāmah-i Iqtisādī, 2012
Stock market crashes are important, both for investors and academics. Since Catastrophe Theory is a strong tool for explaining nonlinear phenomena, in this paper we apply Catastrophe theory and fit stochastic Cusp Catastrophe model to Tehran Stock ...

Non-linear Dynamic Shifts in Distress After Wildfires: Further Tests of the Self-Regulation Shift Theory

Frontiers in Psychology, 2020
Worldwide exposure to explosive wildfires has become increasingly common. The psychological impact of these fires is substantial, demanding a deeper understanding of post-wildfire adaptation.
