The aim of the present paper is to investigate of some properties of periodic solutions of a nonlinear autonomous parabolic systems with a periodic condition.We investigate parabolic systems of differential equations using an integral manifolds method of the theory of nonlinear oscillations.We prove the existence of periodic solutions in an autonom
Aiming at the correlated and cascading failures caused by large-scale Quadra disasters,a post-disaster service restoration scheme was proposed.This scheme utilized global service bandwidth concession and the limited lifetime of local links to mitigate resource crunch in the post-disaster network.According to their bandwidth and holding time require
In electrical engineering, Brushless Direct Current (BLDC) motors are frequently used in mechanical applications because of their effectiveness, strong torque, and small design.Nevertheless, reaching peak performance and making accurate adjustments to parameters can be difficult when using a simple, customized Proportional Integral Derivative (PID)

Abstract Background Small supernumerary marker chromosomes (sSMC) are additional centric chromosome fragments too small to be identified by banding cytogenetics alone.A sSMC can originate from any chromosome and it is estimated that 70% of sSMC are de novo, while 30% are inherited.Cases of sSMC derived from chromosome 5 (sSMC5) are rare, accounting
