dynamical variable

dynamical variable

[dī¦nam·ə·kəl ′ver·ē·ə·bəl]
(mechanics)
One of the quantities used to describe a system in classical mechanics, such as the coordinates of a particle, the components of its velocity, the momentum, or functions of these quantities.

For the analysis of the climatology of the thermodynamic (CAPE in J/kg and CIN in J/kg) and dynamical variable Omega in Pa/s on 2.5[degrees] x 2.5[degrees] resolution, data were downloaded from NOAA-CIRES 20th Century Reanalysis version 2 [22] (http:// www.esrl.noaa.gov/psd/data/gridded/data.20thC_ReanV2.html).
These differ with respect to the role that information plays in each and whether information functions as a dynamical variable in the top-down constraining process.
Each of neural structures other than striatum is modeled by a single state variable, thus [gp.sub.e], [gp.sub.i], stn and thl are represented by a single dynamical variable and they all have afferent and efferent connections, corresponding to the circuit given in Figure 1.
In principle the quantum uncertainty does not prevent knowing exactly one dynamical variable only; being the size of all ranges arbitrary by definition, one must admit even the chance [DELTA]x [right arrow] 0 that means local position of a particle exactly known.
The new dynamical variable is called momentum p; referred to the volume, it more precisely represents a temporal flow of matter, i.e., the quantity of matter crossing a unit area per unit time.
Here z is the third independent dynamical variable, [[omega].sub.f] is its characteristic rate, and k is the feedback coefficient.
admitting that both dynamical variable concur to describe any physical system, requires [[upsilon].sub.x] [less than or equal to] [[upsilon].sub.max]; eqs.
However (7) cannot be entirely expressed in terms of g because the fundamental dynamical variable is v.
However (16) cannot be entirely expressed in terms of g because the fundamental dynamical variable is v.
Among the topics are the linearity of quantum mechanics and the birth of the Schrodinger equation, sewing Greenberger-Horne-Seilinger states with a quantum zipper, deriving free quantum field theory from information theory, Casimir forces in spherically symmetric dielectric media, and some consequences of mass and proper time as dynamical variables.

We point out that the CL model is a 1D model where the dynamical variables (as the generalized coordinates) are only the function of time-evolution parameter.
Hence, the counting of degrees of freedom is carried out in the following form: there are 6 dynamical variables [A.sup.i.sub.a] and 6 independent FJ constraints [[OMEGA].sup.(0)i.sub.1], [[OMEGA].sup.(0)i.sub.2]; in this manner, the theory is devoid of degrees of freedom, and the theory is topological as expected.
