Dark energy and dark matter are two of the biggest mysteries of modern cosmology, and our understanding of their fundamental nature is incomplete. Many parametrizations of couplings between the two in the continuity equation have been studied in the literature, and observational data from the growth...
The Stability of Solitary Waves The Korteweg-de Vries equation, which describes the unidirectional propagation of long waves in a wide class of nonlinear dispersive systems, is well known... TB Benjamin - 《Proceedings of the Royal Society A Mathematical Physical & Engineering Sciences》 被引量: ...
In the direct mode, two motion vectors of both directions are derived from a motion vector of a co-located block in a neighboring picture on the basis of a temporal redundancy characteristic that motion continuity is constantly maintained between two adjacent pictures. This direct mode has an ...

angles is also discussed.A three-dimensional wind field can be constructed using the dual-Doppler equations from FAST data using the two radial velocity estimates and vertical integration of the continuity equation with a boundary condition of no vertical motion at cloud top and the Earth's ...
This secular equation was derived by expanding directly a six-order determinant originated from the traction-free conditions at the top surface of the layer and the continuity of displacements and stresses through the interface between the layer and the half-space. Since the expansion of this six-...
It is also assumed that the dispersed phase is well described by a "Boltzmann-type" equation and Eulerian "continuity", momentum and fluctuating kinetic energy equations for the dispersed phase are obtained. A k - turbulence model for the continuous phase is used. A gradient transport model is...

The continuity and boundary conditions for the resulting self-adjoint integro-differential equation are explicitly constructed. A variational principle is then set up by devising a self-adjoint Lagrangian whose minimum property is equivalent to the symmetrized Boltzmann equation with the associated ...
where ΣLADj is the cumulative leaf area density (m²/m³) from the top of the forest (j = n) down to the height layer j = i+1. The parameter k in Equation (8) represents the average light extinction coefficient (k = 0.2 for near-infrared or infrared signals with wavelengths ...
