Abstract Topological photonic crystals, which offer topologically protected and back-scattering-immune transport channels, have recently gained significant attention for both scientific and practical reasons.Although most current studies focus on dielectric materials with weak dispersions, this study focuses on topological phases in dispersive mate
Grinding is a critical method for enhancing the quality of worm tooth surfaces, and its process optimization has long been a significant research focus; however, existing methods Solid spoon are insufficient in addressing the nonlinearity and complexity inherent in the grinding of complex surfaces.In this study, a three-objective optimization funct
Meta-heuristic algorithms have become an arising field of brightening lotion research in recent years.Some of these algorithms have proved to be efficient in solving combinatorial optimization problems, particularly knapsack problem.In this paper, four meta-heuristic algorithms are presented particle swarm optimization, firefly algorithm, flower po
Education has a momentous and influential role in developing Cultural Art this country.The specific function of educational management may not be fully depended on the central government.In line with local autonomy era, local government (municipality) must also be able to initiate and play its extended role in order to enhance the educational quali
