Starting with the Langevin equation, the Ito calculus leads to the Fokker-Planck Equation, ((partial deriv)p)/((partial deriv)t) = (partial deriv)/((partial deriv)x) (partial deriv)/((partial deriv)x) (ap) - bp, (1) describing the motion of a particle undergoing diffusion a(x,t)...
Thekey feature of the PFEM is the use of a Lagrangian description to modelthe motion of nodes (particles) in both the fluid and the structure domains.Nodes are thus viewed as particles which can freely move and even separatefrom the main analysis domain representing, for instance, the effect...
It derives equations of motion to evaluate the contact force by reflecting the effects due to the truncation of kernel support by boundary. While their technique is known to be effective to handle arbitrary geometry in SPH, it is not straightforward to apply it in the MPS schemes. Here, ...

Suppose the position of a particle in motion at time t is given by the vector parametric equation \vec r(t) = < 3(t-2)^2, 6, 2t^3-6t^2 > a) Find the velocity of the particle at time t. Use the given acceleration function to fin...
The derivation of the equations of motion diverges from a direct application of the Euler–Lagrange equations, as these lack a general form in the fractional Laplacian context. Instead, we rely on specific technical aspects of fractional calculus. The first crucial element is a well-known inversion...
Back in school, I remember that it wasn’t until I started taking classes in physics that calculus made any kind of real sense to me. I just need diagrams to function. In that spirit, I thought it would be nice to go overFitts’s Law, a staple in the HCI diet, with a few visual...
