maximum velocity


Also found in: Acronyms.

max·i·mum ve·loc·i·ty (Vmax),

1. the maximum rate of an enzyme-catalyzed reaction that can be achieved by progressively increasing the substrate concentration at a given enzyme concentration; in cases of substrate inhibition, Vmax is an extrapolated value in the absence of such inhibition; Compare: Michaelis-Menten equation.
2. the maximum initial rate of shortening of a myocardial fiber that can be obtained under zero load; used to evaluate the contractility of the fiber.

A maximum velocity of 12 m/s is recorded for E30 while 8 m/s is arrived by the kerosene spray.
The velocity profiles are analyzed to find the flow pattern and movement of the local maximum velocity at different sections along the meander path in-between two successive bend apex regions.
Compared to the results on the direction [mathematical expression not reproducible] of posture (1), intuitively at posture (2), lower-limb end-effector's maximum velocity decreases on direction [mathematical expression not reproducible], so that slave-active joint D is able to use lower velocity to shadow lower limb's movement in this direction, where in this case assistive mechanism also can assist the lower limb much better on this direction; at posture (3), the distance between D and C" becomes much shorter, leading that even slave-active joint D uses its maximum velocity, assistive mechanism still cannot shadow and assist the lower limb on direction [mathematical expression not reproducible].
In order to better understand how our proposed velocity control and separation strategy achieves fuel-saving under the premise of guaranteeing that maximum number of vehicles can pass the intersection without idling, we implement another simulation in which all the vehicles choose the maximum velocity to pass intersections without considering fuel-saving.
This phenomenon can be realized by modifying the maximum velocity [v.sub.max] of the NS model.
The confluence of the Yangtze and Wanhe rivers is divided into the following six zones: flow deflection, flow stagnation, flow separation, maximum velocity, shear layer, and the mainstream (Best, 1987).
They indicated that numerical, ANN and experimental results could show that the maximum velocity occurs under the free-surface but the analytical solution could not.
Where N is the sample number and vmax is the maximum velocity of all mobile nodes.
In other words, personal protection might mean a light- to medium-weight jacketed hollowpoint bullet launched at near maximum velocity. Hunting loads typically have heavy jacketed or hard-cast gas-checked bullets stepping out with the most energy you can handle.
If it is the goal to set the vehicle in motion at the point in time [t.sub.0] and to return to the stillstand [t.sub.f], the possible maximum velocity decreases with the reduction of the replacement cycle's length [DELTA]t = [t.sub.f] - [t.sub.0].
