This paper deals with a quasilinear parabolic system coupled via both Roshe Run Canada
nonlinear reaction terms and nonlinear boundary flux. As the results of the interaction among the multi-coupled nonlinearities in the system, some appropriate conditions for global existence and global nonexistence of solutions are determined respectively.
This paper is devoted to the main problem of external ballistics, i.e., the problem of finding a trajectory of a material point, which starts in the given initial set, reaches the given target set at time to be determined, and satisfies the dynamics law as well as some optimality constraint, while the absolute value of its initial velocity is given.
A 4-point interpolatory subdivision scheme with a tension parameter is analysed. It is shown that for a certain range of the tension parameter the resulting curve is C1. The role of the tension parameter is demonstrated by a few examples. The application to surfaces and some further potential generalizations are discussed.
