Hopf bifurcation analysis in a delayed model of tumor therapy with oncolytic viruses [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2021 The stability and Hopf bifurcation of a nonlinear mathematical model are described by the delay differential equation proposed by Wodarz for interaction between uninfected tumor cells and infected tumor cells with the virus.

Introduction to bifurcation-theory [PDF]
, 1991 The theory of bifurcation from equilibria based on center-manifold reductio, and Poincare-Birkhoff normal forms is reviewed at an introductory level. Both differential equations and maps are discussed, and recent results explaining the symmetry of the ...

Bifurcation analysis of a special delayed predator-prey model with herd behavior and prey harvesting
AIMS Mathematics, 2021 In this paper, we propose a predator-prey system with square root functional response, two delays and prey harvesting, in which an algebraic equation stands for the economic interest of the yield of the harvest effort.

Bifurcation Flight Dynamic Analysis of a Strake-Wing Micro Aerial Vehicle
Applied Sciences, 2021 Non-linear phenomena are particularly important in -flight dynamics of micro-class unmanned aerial vehicles. Susceptibility to atmospheric turbulence and high manoeuvrability of such aircraft under critical flight conditions cover non-linear aerodynamics

Experiment and Theoretical Analysis Study of ETFE Inflatable Tubes
International Journal of Aerospace Engineering, 2014 The load bearing capacity of an ETFE (ethylene-tetra-fluoro-ethylene) inflatable tube is tested in this paper, and a comparative study of two wrinkling theories, the bifurcation theory and the tension field theory, is carried out for wrinkling analysis ...
