This paper argues that both Keynes and Minsky held a concept of financial instability which may be properly understood only in terms of structural instability, and not –as is usual-in terms of the traditional concept of economic instability, i.e. dynamic instability. Keynes is quite explicit in denying that the dynamic instability of a monetary economy is a particularly serious problem; on the ...

The dynamics of micro/nanoelectromechanical systems (M/NEMS) is a core research area in micromechanics. Due to the nonlinearities and singular nature actuation forces that emerge these systems, it has become promising challenging area. foremost objective this manuscript examine M/NEMS by approximating rational terms involved structures. An switch under electromagnetic force adopted reveal effec...

In recent years, underactuated nonlinear dynamic systems trajectory tracking, such as space robots and manipulators with structural flexibility, has become a major field of interest due to the complexity and high computational load of these systems. Hierarchical sliding mode control has been investigated recently for these systems; however, the instability phenomena will possibly occur, especia...

Dynamic instability-the switching of a two-state polymer between phases of steady elongation and rapid shortening-is essential to the cellular function of eukaryotic microtubules, especially during chromosome segregation. Since the discovery of dynamic instability 20 years ago, no other biological polymer has been found to exhibit this behavior. Using total internal reflection fluorescence micr...
