More precisely, the time derivative of L is the torque that is the cross-product of r and F:Equation 4Then the angular velocity w, whose norm is the spinning speed, is derived from the angular momentum L:Equation 5where the 3x3 matrix I(t) is the inertia tensor at time t and I(t...
Equation (68) emphasizes that the shifted charge function can be taken to be time dependent, and we will assume that this time dependence is expressed as the time derivative of a fixed function f0(t). The solution for the electric field is thus of the form $${{{\bf{E}}}_{Q}^{\pr...
For example, one particular TFD discussed in Section 2.5.1 is defined as the time derivative of the squared magnitude of the “running spectrum,” that is, spectrum of the signal from −∞ to time t: (I.2.2)ρz(t,f)=∂∂t∫−∞tz(u)e−j2πfudu2. The truncation of the...
This derivation is for a multidimensional Markov process. We start with the definition of a time-derivative for a probability density but place no ... M Ullah,O Wolkenhauer 被引量: 11发表: 2006年 Controlled Markov Fields with Finite State Space on Graphs Discrete time Markov chains with multi...

Commonly used retrieval algorithms include the peak point of the first derivative (DER), the peak of the waveform (MAX), and the half-power point (HALF) [8,12,13]. Obtaining the inversion delay requires correction of numerous parameters including the receiver and transmitter orbits, ionospheric...
Find the changing of the vector potential by rewriting the ideal Equation (3) in the form of the full time derivative: 𝐀𝑡=[𝐯,curl(𝐀)]or(𝐴𝑖)𝑡=𝑣𝑗∇𝑖𝐴𝑗−𝑣𝑗∇𝑗𝐴𝑖⇒(𝐴𝑖)𝑡+𝑣𝑗∇𝑗𝐴𝑖=−𝐴𝑗∇𝑖𝑣𝑗+∇𝑖...
Time to market (TTM) is the length of time to develop a product from conception until it is released to the market and is available for sale.
Figure 5a shows the time evolving inter-fragment velocity, corresponding to the time derivative of the distance between the H3+ and COH+ products. Before dissociation occurs, the inter-fragment velocity exhibits oscillations between positive and negative values, reflecting the roaming H2 motion away ...
