Non-uniform rational B-spline (NURBS) interpolator has been widely used in modern manufacturing systems to machine arbitrary geometries with great relief of the data flow bottleneck and feedrate fluctuation. However, in practice, real-time feedrate does not always meet the computer numerical control (CNC) command exactly subject to the system dynamics. To solve this problem, we present a real-t...

An analysis is reported here for three-time level integration methods following the global spectral analysis (GSA) described in High Accuracy Computing Methods , T.K. Sengupta, Cambridge Univ. Press, USA. The focus is on the second order Adams–Bashforth (AB2) and the extrapolation in time (EXT2) methods. Careful distinction is made for the first time step at t = 0 by either Euler forward or fou...

A multistep flux-corrected transport (MFCT) scheme is developed to achieve conservative and monotonic tracer transports for multistep dynamical cores. MFCT extends Zalesak twotime level scheme to any multistep time-differencing schemes by including multiple highorder fluxes in the antidiffusive flux, while computing the two-time level low-order monotone solution. The multistep time-differencing...

A numerical simulation of steady and unsteady two-dimensional flows past cylinder with dimples based on highly accurate pseudospectral method is the subject of the present paper. The vorticity and streamfunction formulation of two-dimensional incompressible NavierStokes equations with no-slip boundary conditions is used. The system is formulated on a unit disk using curvilinear body fitted coor...

There are still mathematical predictions in the fight against epidemics. Speedy expansion, ways and procedures for pandemic control require early understanding when solutions with better computer-based modeling prognosis developed. Despite high uncertainty each of these models, one important tools public health management system is epidemiology models. The fractional order shown to be more effe...

The aim of this work is to design a stochastic framework solve the fractional-order differential model based on breast cancer progression during immune-chemotherapeutic treatment phase, including certain control parameters such as anti-cancer medications, ketogenic diet and immune boosters. developed considers tumor density throughout chemotherapy treatment, well an response normal cell–tumor c...

We analyze the behavior of an ensemble time integrators applied to semi-discrete problem resulting from spectral discretization equations describing Boussinesq thermal convection in a cylindrical annulus. The are cast their vorticity-streamfunction formulation that yields differential algebraic equation (DAE). comprises 28 members: 4 implicit-explicit multistep schemes, 22 Runge-Kutta (IMEX-RK)...
