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...

In this paper, a generalized Adams-Moulton method that is a m-step method derived by using the Taylor’s series is proposed to solve the satellite orbit determination problem. We show that our proposed method has produced much smaller error than the original Adams-Moulton method. Finally, the accuracy performance is demonstrated in the satellite orbit correction problem by giving a numerical exa...

High-accuracy schemes have been proposed here to solve computational acoustics 4 and DNS problems. This is made possible for spatial discretization by optimizing 5 explicit and compact differencing procedures that minimize numerical error in the 6 spectral plane. While zero-diffusion nine point explicit scheme has been proposed 7 for the interior, additional highaccuracyone-sided stencils have ...

This paper proposed the high-precision satellite orbit prediction process at the user end for the real-time precise point positioning (PPP) system. Firstly, the structure of a new real-time PPP system will be briefly introduced in the paper. Then, the generation of satellite initial parameters (IP) at the sever end will be discussed, which includes the satellite position, velocity, and the sola...

The Adams apportionment method is the only divisor method that consistently favors small districts relative to the Hamilton method. The Jefferson method is the only divisor method that favors large districts relative to the Hamilton method. These statements hold for the Balinski and Young [3] interpretation of "favoring small/large districts," and for the partial "majorization ranking" introduc...

in this paper, a new spectral-iterative method is employed to give approximate solutions of fractional logistic differential equation. this approach is based on combination of two different methods, i.e. the iterative method cite{35} and the spectral method. the method reduces the differential equation to systems of linear algebraic equations and then the resulting systems are solved by a numer...

This paper studies on the mechantronic system of parallel robot by using interface technique between ADAMS and MATLAB software. MATLAB/Simulink is used to model the control concepts which drive the dynamics of the system based on sensor feedback, while ADAMS is used to model the mechanical parts of the system that are influenced by the geometric layout and by external loads and forces. The simu...

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...
