Momentum transfer and friction in the debris of rock avalanches: Discussion The well known Voellmy runout equation is routinely used to dimension protective barriers for snow avalanches. This paper shows that the Takahashi and Yoshida runout equation for debris flows can be easily adapted to snow ...
The objective of this new model is to increase the accuracy of the numerical simulations by solving the Poisson's equation for calculating the electric field, and replacing the ambipolar diffusion assumption by solving the momentum conservation equations of charged particles. This new approach removes ...
There are three main methods used for calculating option values: partial differential equations, simulation, and lattice methods (Mun, 2006b), which we introduce below. 3.2.1 Partial differential equations Partial differential equations are a continuous time, analytical, mathematical approach to valuing ...

Firstly, based on thecharacteristic equationand angular momentum conservation equation of the FFSR, the generalized Jacobian matrix is obtained. Thecharacteristic equationof calculating the thaw bulb was drawn by mathematical simplification, and a satisfied solution was obtained by difference method. ...
Transformation of the equation of conservation of momentum from rectangular to spherical coordinates yields a linearized relation between radial particle acceleration and radial pressure gradient of the same form as for the plane wave: (3.42)∂p/∂r=−ρ0∂ur/∂t There is no tangential com...
We formulate a computationally feasible method for calculating multiphoton ionization rates for atoms exposed to intense fields in the intensity regime whe... RM Potvliege,R Shakeshaft - 《Physical Review A》 被引量: 205发表: 1988年 Dissociative ionization of D_ {2} in intense laser fields: D...
For example, if v2 is greater than v1 in the equation, then P2 must be less than P1 for the equality to hold. Example 1. Calculating Pressure: Pressure Drops as a Fluid Speeds Up In Example 1 from Flow Rate and Its Relation to Velocity, we found that the speed of water in a hose...
The importance of Atomic Form Factors (f) is well-known to the scientific community. Tabulated values for f are mostly used in calculating cross-sections and Monte Carlo sampling for the coherent scattering of photons. The uses of these values are subjec
