Modelling, Analysis and Calculation of Cerebral Hemodynamics
Mathematical models of cerebral hemodynamics, applicable to humans and rats have been developed and analysed with the purpose of reaching a deeper insight to which degree experimental results on rats can be extrapolated to humans and to clinical management of patients. These models include regulation mechanisms involving the small cerebral arteries and

A delayed mathematical model for testosterone secretion with feedback control mechanism
A mathematical model describing the biochemical interactions of the luteinizing hormone (LH), luteinizing hormone‐releasing hormone (LHRH), and testosterone (T) is presented. The model structure consists of a negative feedback mechanism with transportation and secretion delays of different hormones. A comparison of stability and bifurcation analysis in

A nonlinear two‐species oscillatory system: bifurcation and stability analysis
The present paper dealing with the nonlinear bifurcation analysis of two‐species oscillatory system consists of three parts. The first part deals with Hopf‐bifurcation and limit cycle analysis of the homogeneous system. The second consists of travelling wave train solution and its linear stability analysis of the system in presence of diffusion.

Diffusive instability in a prey‐predator system with time‐dependent diffusivity
An ecological model for prey‐predator planktonic species has been considered, in which the growth of prey has been assumed to follow a Holling type II function. The model consists of two reaction‐diffusion equations and we extend it to time‐varying diffusivity for plankton population.

Parametrically excited nonlinear systems: a comparison of two methods
Subharmonic resonance of two‐degree‐of‐freedom systems with cubic nonlinearities to multifrequency parametric excitations in the presence of three‐to‐one internal resonance is investigated. Two approximate methods (the multiple scales and the generalized synchronization) are used to construct a first‐order nonlinear ordinary differential equations ...

Shift of bifurcation point due to noise induced parameter
The object of the paper is to see the effect of small stochastic parametric perturbation on a nonlinear interacting system exhibiting Hopf bifurcation. The method is based on the technique of Markov diffusion approximation.

Periodic solutions of second order Hamiltonian systems bifurcating from infinity [PDF]
The goal of this article is to study closed connected sets of periodic solutions, of autonomous second order Hamiltonian systems, emanating from infinity. The main idea is to apply the degree for SO(2)-equivariant gradient operators defined by the second

Computation of periodic solution bifurcations in ODEs using bordered systems [PDF]
We consider numerical methods for the computation and continuation of the three generic secondary periodic solution bifurcations in autonomous ODEs, namely the fold, the period-doubling (or flip) bifurcation, and the torus (or Neimark–Sacker) bifurcation.
