First of all, the governing equations of motion of cables unwinding from a cylindrical spool package were systemati-cally derived using the extended Hamilton’s principles of an open system in which mass is transported at each boundary. And the modi-fied finite difference methods are suggested to...
Derivation and testing of explicit equations of motion for polymers described by internal coordinates General Lagrange's equations of motion for a system of polymeric molecules are obtained in an explicit form. They can be used for simulating molecular dyna... AK Mazur,VE Dorofeev,RA Abagyan - ...

Cylindrical coordinatesA change of variables on the Cartesian equations will yield the following momentum equations for r, φ, and z:The gravity components will generally not be constants, however for most applications either the coordinates are chosen so that the gravity components are constant or ...

摘要: To analyze electromagnetism in spinning media, we use, differently than previous works, a relativistic description of rotations. We give the form of Maxwell's equations in the laboratory and corotating frames in terms of cylindrical coordinates. Possible applications are discussed....
We further apply our method to the Navier–Stokes equations of motion in polar coordinates. This paper is organized as follows: In Section 2, we derive the off-step discretization for a scalar nonlinear 3D parabolic equation, and then extend the method to a quasi-linear equation. In Section ...
