The separable form call be applied to obtain general reflection relations for a vector field at simple surfaces. Such reflection relations enable us to solve the flow equation with specified conditions at different disconnected bodies like the sphere and the cylinder. The main focus of this article...
This produces tendencies (rates of change) used by an implicit–explicit ordinary differential equation (ODE) solver to advance the state in time. The new model state xt+1 can then be fed back into another time step, or decoded into model predictions. b, The learned physics module, which ...
They managed different approaches and variables to define the resistance formula applicable to that type of granular media. Based on the analysis of the different approaches and experimental data obtained by the corresponding authors, we propose a unified general seepage equation applicable to large-...
Now consider a dynamic economic model (where agents are forward-looking) with a small enough number of state variables that the model can be solved numerically. With one of these state variables playing the role of global temperature in the above equation system, one can imagine adding a large...

Find the general solution of the given differential equation, and use it to determine how solutions behave as $ t\to\infty$ $y'+y=5\sin{2t}$ ok I did this first $u(t)y'+u(t)y=u(i)5\sin{2t}$ then $\frac{1}{5}u(t)y'+\frac{1}{5}u(t)y=u(i)\sin{2t}$ so far ...
The paper includes a detailed presentation of a "standard" CGE model (an equation-by-equation description) and its required database. It incorporates features developed in recent years in research projects conducted at IFPRI. These features, which are of particular importa...
Robert Wald, in General Relativity, equation (4.2.8) says : E = – pa va where E is the energy of a particle, pa the energy-momentum 4-vector and va the 4-velocity of the particle. How can I see this is compatible with the common energy-momentum-relation E2 – p2 =... carpinus...
