Moreover, we show that liquidity assumptions are not needed to the same extent as in classical option pricing theory because continuous trading is not necessary to replicate ILWs when using cat bonds; that is, astatic hedging approach is sufficient, which also reduces transaction costs and possible tracking errors.

In published scientific research, the results of the analysis are presented and methods for synthesizing two-mass electromechanical systems (EMS) based on various optimization criteria are proposed, as a rule, without consideration of the interaction effects of subsystems [7-9], therefore it is of interest to investigate electric drives with an astatic system of automatic regulation and minimization of vibrational components of processes under the action of variable friction forces and optimal (limiting) electromechanical interaction.
The wavelength of the resonances can be tuned in astatic way, by properly engineering the nanostructure composition, shape and size, or a dynamic way through changes in the surrounding medium (its temperature, refractive index, illumination, and so on) [1-7].
