where F is force in dynes and x is distance in cm. The kinetic energy variable, the flow variable that results from force, is velocity: (9.7)υ=dxdtcm/sec Velocity is directly related to the kinetic energy of a mass by the well-known equation: (9.8)E=12mυ2 Power in mechanical syste...
In the whole operation process of a compressor, the voltage space vector of a stator is modulated according to a frequency (revolving speed) set value; the amplitude and the revolving speed of the voltage space vector are adjusted; the amplitude of a revolving magnetic field of the stator is...
To our interest, the convection patterns and convective velocity have the 214 ACTA SEISMOLOGICA SINICA Vol.18 Figure 2 The convection patterns of toroidal field at Rayleigh number Ra=10 000 and r=1.74 (about 1 500 km deep) C1=0.1. (a) R-R boundary, the minimum is 0.02, the maximum ...
has with time. It’s not a function of time, and I have no idea what you’re doing by defining it as such. To the best of my knowledge, in the ODE solvers, time is a discrete, single scalar value at each step. It is not a vector.is...
Cauchy's theorem is basically a simplified version of Stokes's integral theorem (1.5). Suppose that the surface S is located in the (x, y)-plane of ℜ3 (see fig.1.6). The vector dS is then equal to dx dy (0, 0, 1), and dl points in the anti-clockwise direction. Consider fi...
Formal optimization requires a definition of a performance metric, which is normally a scalar function of adjustable parameters (typically, antenna dimensions), but might also be vector-valued in the case of multi-objective design. In this work, we do not consider multi-objective design84, ...
A variable can be a character vector, cell array, or structure. Velocity: e.g., {'U','v','w'}— Velocity state name '' (default) | comma-separated list surrounded by braces Position: e.g., {'Xe','Ye','Ze'}— Position state name '' (default) | comma-separated list ...
