Stroboscopic phase portrait and strange attractors

Physics Letters A, 1978
Abstract External periodic modulation of a nonlinear oscillator may lead to a chaotic output behaviour. This phenomenon is attributed to the existence of a strange attractor, which embodies essentially a folding motion as is met in Bernoulli shift or the Baker's transformation.

The phase plane portrait

1983
Since frequency response techniques and root locus diagrams are not applicable to a nonlinear process, there is an important need for a graphical tool to allow nonlinear behaviour to be displayed. This need is filled by the phase plane diagram. The method is applicable to second-order processes without input, although effects equivalent to step or ramp

Phase Portraits of the Proliferation-Quiescence Decision

Science Signaling, 2013
The ON-OFF status of the CDK2-RB bistable switch, rather than a particular time point, defines the restriction point.

Lite2Relight: 3D-aware Single Image Portrait Relighting

International Conference on Computer Graphics and Interactive Techniques
Achieving photorealistic 3D view synthesis and relighting of human portraits is pivotal for advancing AR/VR applications. Existing methodologies in portrait relighting demonstrate substantial limitations in terms of generalization and 3D consistency ...

Analyzing oriented textures through phase portraits

[1990] Proceedings. 10th International Conference on Pattern Recognition, 2002
An attempt is made to develop a solution for signal-to-symbol transformation in the domain of flowlike or oriented texture. The geometric theory of differential equations is used to derive a symbol set based on the visual appearance of phase portraits. This theory provides a technique for describing textures both qualitatively and quantitatively.

Economy Phase Portraits

1976
Topological terms like attractors and basins are expected to play an ever increasing role in the qualitative description of systems described by differential equations. This paper illustrates those concepts through a detailed study of the phase portraits of various "economic models" treated in the Energy Program of IIASA.
