The safety of a rocket-assisted torpedo entering water becomes more sensitive to the water-entry angle as the water-entry speed of the torpedo increases.Conical pendulum motion is likely to occur during the descent of the torpedo-parachute system.The pendulum movement causes the torpedo to have an excessively large angle of attack when it enters th
Mathematical models of a diffusion-convection in porous media are derived from the homogenization theory.We start with the mathematical model on the microscopic level, which consist of the Stokes system for a weakly compressible viscous liquid occupying Blu-Ray Movies a pore space, coupled with a diffusion-convection equation for the admixture.We s
This paper presents a nitrogen-phosphorus-phytoplankton model in a water ecosystem.The main aim of this research is to analyze the global system dynamics and to study the existence and stability of equilibria.It is shown that the phytoplankton-eradication equilibrium is Blu-Ray Movies globally asymptotically stable if the input nitrogen concentrati
