Dynamic optimization flow control

42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004
In this paper, we introduce a class of flow control problems in a network which involves dynamic optimization. As opposed to the static flow control problem where the source rates are determined as a result of a static optimization problem, in our formulation the rates are adjusted according to the solution of an infinite-horizon discounted optimal ...

Information flow dynamics in the brain

Physics of Life Reviews, 2012
Timing and dynamics of information in the brain is a hot field in modern neuroscience. The analysis of the temporal evolution of brain information is crucially important for the understanding of higher cognitive mechanisms in normal and pathological states. From the perspective of information dynamics, in this review we discuss working memory capacity,

Flow Dynamics in the Human Aorta

Journal of Biomechanical Engineering, 1993
The aorta is the major blood vessel transporting blood pumped by the left ventricle to the systemic circulation. The tricuspid aortic valve at the root of the aorta provides a centralized flow with nearly uniform velocity profile into the ascending aorta.

Flow dynamics of the crocodilian heart

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1989
We report for the first time the flow events corresponding to the pressure patterns in the left and right aorta (LAo and RAo) during the cardiac cycle in the caiman (Caiman crocodylus ssp). These experiments show a complex LAo flow pattern; an initial small anterograde flow in the early systole is reversed to a backflow at midsystole.

Gas Dynamics and Reacting Flows

1996
Let us consider a fluid in a local thermodynamical equilibrium. Then we know from thermodynamics that the thermodynamical state of the fluid is completely determined by any two thermodynamic variables. Most often, we shall note by the same letter the corresponding mathematical functions, though they differ.

Reactions in flows with nonhyperbolic dynamics

Physical Review E, 2004
We study the reaction dynamics of active particles that are advected passively by 2D incompressible open flows, whose motion is nonhyperbolic. This nonhyperbolicity is associated with the presence of persistent vortices near the wake, wherein fluid is trapped.
