Among public facilities, facilities belonging to Multi-Group (I) include high-rise buildings, tunnels, and subway stations, and the location of Shelter in Place (SIP) is an important factor in the safety of citizens.However, subway evacuation maps usually induce evacuation to ground level or the tunnel of a subway platform without considering the l

The paper presents two methods to improve the efficiency of supersonic flow simulation using arbitrarily shaped unstructured grids.The first method promotes increasing the numerical solution convergence rate and is based on the geometric multigrid method for initialization of the flow field.The method is used to obtain the initial field of distribu

Background and Objectives: The goal of the paper is to study the influence of noise on generalized synchronization in unidirectionally coupled systems with a complex topology of attractor.As the systems under study, two models of chaotic systems with two-sheeted topologies of attractors such as Lorenz and Chen systems are considered.Materials and M
