In the present manuscript, a discrete-time predator-prey system with prey immigration is considered.The existence of the possible fixed points of the system and topological classification of coexistence fixed point are analyzed.Moreover, the existence and the direction for both Neimark-Sacker bifurcation and flip bifurcation are investigated by Ped
In this work, Charm we introduce a new concept of the stream function and derive the equation for the stream function in the three-dimensional case.To construct a basis in the space of solutions of the NavierStokes system, we solve an auxiliary spectral problem for the bi-Laplacian with Dirichlet conditions on the boundary.Then, using the formulas
A set of systematical optimum operational parameters for wind turbines under various wind directions is derived by using combined momentum-energy and blade-element-energy concepts.The derivations are solved numerically by fixing some parameters Lenses at practical values.Then, the interactions between the produced power and the influential factors
This paper concentrates on improving a text-based human-machine interface integrated into a robotic wheelchair.Since word prediction is one of the most common methods used in such systems, the goal of this work is to BEDHEAD improve the results using this specific module.For this, an exponential interpolation language model (LM) is considered.First
In the context of globalization, some companies have developed beyond the perspectives of their borders, becoming multinational companies.This way of development confers multiple advantages that can generate efficiency, competitiveness and profit.The decisions on which companies base their choice of states Patchouli take into account aspects such a
