Cerebral Hemodynamics and Its Oxygenation: Study of Their Baseline and Spontaneous Oscillation
… cerebral vasomotion was investigated by use of phase portrait, cross-correlation, and nonlinear dynamics analytical methods. We found that the cerebral vasomotion is temporally coherent as well as spatially coherent. The correlation lengths for temporal and spatial coherence are about 3min and …

Stability analysis and control for bipedal locomotion using energy methods
… for the first time the notion of the energy portrait analysis originated from the phase portrait. The energy plane is spanned by the total energy of the system and its derivative, and different energy trajectories represent the energy portrait in the plane. One of the advantages of this …

Catenaries in Viscous Fluid
… for the tangential angle of the body ($theta$). Phase portraits in the angle-curvature ($theta,partial_s theta$) plane are generated, that can be shown to be $pi$ periodic after appropriate scaling and reflection operations. The rich parameter space allows for different kinds of phase portraits …
