We study the stability characteristics of zero-velocity gap solitons in dual-core Bragg gratings with cubic-quintic nonlinearity and dispersive reflectivity. The model supports two disjointed families of gap solitons (Type 1 and Type 2). Additionally, asymmetric and symmetric solitons exist in both Type 1 and Type 2 families. A comprehensive numerical stability analysis is performed to analyze the stability of solitons. It is found that dispersive reflectivity improves the stability of both types of solitons. Nontrivial stability boundaries have been identified within the bandgap for each family of solitons. The effects and interplay of dispersive reflectivity and the coupling coefficient on the stability regions are also analyzed.

With the development of linux and μC/O dual-core embedded operating system, its research areas have been broadened wider and wider. This paper aims to illustrate its importance in engineering practice on the basis of its application in the technological process of injection molding machines and numerical control machines to arrive at its natural conclusion that dual-core system has a brighter and wider prospect by using Linux and μC /OS to solve the problems of Linux because it is more and more widely applied in engineering, mechanical control systems and many other fields such as mobile communications as well as digitalized network, and now is becoming more and more demanded with the rapid development of scientific technology.
