Mathematical methods in the applied sciences
The center task of this paper is to give the qualitative and quantitative investigations into the nonlinear dynamics of the new extended Korteweg–de Vries–type equation for shallow‐water waves.

Phase Portraits of Quantum Systems
Few-Body Systems, 2013We formulate a general approach to construct phase portraits of a quantum system in the Fock–Bargmann space. This approach is applied to simple model problems and two-cluster nuclei as well.

IEEE transactions on power electronics
A hybrid parallel-connected system with grid-following (GFL) and grid-forming (GFM) converters can be characterized as a high-order nonlinear dynamic system when performing transient synchronous stability analysis, which cannot be analyzed clearly by the

Phase portrait analysis of super solitary waves and flat top solutions
Physics of Plasmas, 2018The phase portrait analysis of super solitary waves has revealed a new kind of intermediate solution which defines the boundary between the two types of super solitary waves, viz., Type I and Type II.

Consider a dynamical system of two coupled ordinary differential equations (ODEs) of the general structure $$ \dot{x} \equiv \frac{{dx}}{{dt}} = P(x,y),\dot{y} \equiv \frac{{dy}}{{dt}} = Q(x,y) $$ (5.1) where P and Q are known functions of the dependent variables x and y and the independent variable has been taken to be the time t.

Phase portrait of the matrix Riccati equation
SIAM Journal on Control and Optimization, 1986The matrix Riccati equations \(dK/dt=B_{21}+B_{22}K-KB_{11}- KB_{12}K\) (where \(K=K(t)\in {\mathbb{R}}^{m\times n}\) is variable and \(B_{12}\in {\mathbb{R}}^{m\times n}\), \(B_{22}\in {\mathbb{R}}^{m\times m}\), \(B_{11}\in {\mathbb{R}}^{n\times n}\), \(B_{12}\in {\mathbb{R}}^{n\times m}\) are constant matrices) and \(dK/dt=-Q-A'K-KA+KLK\) (where \(K=

Phase portrait in conversation processes
2006Our goal was to extract information on communicative process evolution avoiding simplification and classification. We analysed 50 motivational research interview made from students during their university course. The nature intrinsically interactive of the dialogue concretises, shapes and evolves within time dimension.

At the present time, it is apparently difficult to give a general and exhaustive definition of the phase portait of CDSs considered here. At the present stage of development of the theory, it can be adequately done for a second-order CDS defined on the plane or on a two- dimensional manifold (Sec. 34).

Bifurcations of Phase Portraits
2000The situation that we shall be concerned with in this chapter is the following: we consider a differential system that depends on auxiliary parameters (as in Chapt. 5, we may talk about control parameters, hidden parameters, imperfection parameters, … ) and we wish to understand how the phase portrait changes as the parameters vary.
