Fitting the Cusp Catastrophe in R: A cusp Package Primer [PDF]

open access: yesJournal of Statistical Software, 2009
Of the seven elementary catastrophes in catastrophe theory, the “cusp” model is the most widely applied. Most applications are however qualitative. Quantitative techniques for catastrophe modeling have been developed, but so far the limited availability ...

Roadway rock burst prediction based on catastrophe theory [PDF]

open access: yesScientific Reports
In order to quantitatively calculate the critical depth and critical load of mines affected by rock burst, and to achieve effective prevention and control of rock burst in coal mines, this paper proposes a mechanical model for predicting the occurrence ...

Catastrophe control of aphid populations model

open access: yesMathematical Biosciences and Engineering, 2022
Considering the effect of the natural enemy on aphid populations, the corresponding model with delay is built. The model is analyzed using the qualitative theory of differential equations and catastrophe theory etc.

Research on the Traffic Flow Control of Urban Occasional Congestion Based on Catastrophe Theory

open access: yesJournal of Advanced Transportation, 2021
Aimed at the problem of occasional congestion control, the cusp catastrophe theory is used to establish the catastrophe model of the urban road system under occasional congestion, finding breakpoints and analyzing stability after urban road system ...

On the Butterfly Catastrophe Model and Stability of Finite Periodic Solutions for Some Non-Linear Differential Equations [PDF]

open access: yesKirkuk Journal of Science, 2023
In this work, we find the results for the folded part projection of the butterfly catastrophe model onto the control space, using methods from catastrophe theory to obtain stability and the catastrophic behavior of finite periodic solutions for some non ...

Pricing catastrophe reinsurance under the standard deviation premium principle

open access: yesAIMS Mathematics, 2022
Catastrophe reinsurance is an important way to prevent and resolve catastrophe risks. As a consequence, the pricing of catastrophe reinsurance becomes a core problem in catastrophic risk management field. Due to the severity of catastrophe loss, the Peak

A two-step method for cusp catastrophe model construction based on the selection of important variables

open access: yes工程科学学报, 2023
Sudden transition is a widely existing phenomenon in engineering practice. When the state of the system experiences sudden abrupt transition, calculus-based traditional mathematical modeling methods has low accuracy.
