Engineering structures are often designed and optimized to meet multiple and possiblyconflicting objectives such as the minimum weight and maximum strength.The merit of multiobjectiveoptimization is t
In this paper,we consider an S-shaped piecewise linear supply function and the totaldemand which consists of two components,the real demand and the speculative demand,andthen develop a piecewise linea
In this paper,combination of cubic nonlinearity and time delay is designed to improve theperformance of a viscoelastic isolation system with a power-form restoring force.Based on themethod of multiple
This paper reports the finding of hidden hyperchaos in a 5D hyperchaotic Burke-Shawsystem,which is obtained by adding feedback controllers to the classic Burke-Shaw system.Ofparticular interest is tha
