Of course this equation can be derived in a more rigorous way like other conservation laws, using Gauss’ theorem. The spatial mass density ρ = ρ(t, x) induced by f determines the gravitational potential U according to Newton’s law for gravity, subject to the usual boundary condition at...
Kay's mathematical mixing expression, the Tammann鈥揟ait equation, and empirical equations were used to describe the dependence of the density (蟻, kg/m3) of the mixtures on the volume percentage (v%) of biodiesel mixed with diesel and the temperature variance (T, K). In addition, ...
Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. (Nikola Tesla)Interestingly though, once we have a logical language which describes the mathematical relationship ...

“Black Swan” event. By evaluating the maximum site intensity from this event, we obtain the design site intensity including a technically meaningful safety factor. For the calculation of Arias intensity, we may use an empirical prediction equation as for example (Travasarou et al., 2003) or ...
The motion of a basketball as it leaves a player's hand and passes through the net can be modelled using the equation h=2+1.1x−0.1x2 , where h m is the height of the basketball above the groupd and x m is the horizontal distance travelled. " 根据图可以知道在y轴上的y=2的地方...

Additionally, a sedimentation–dispersion model, similar to the approach proposed by Cova (1966) has been implemented to represent the gravity-driven advective flow of agglomerated, suspended UO2 powder particles, as well as gas-bubble induced turbulent mixing in the suspension.
