Fracmemristor: Fractional-Order Memristor

IEEE Access, 2016
This paper mainly discusses an interesting conceptual framework: the fractional-order memristor (fracmemristor). It is a challenging theoretical problem to determine what the fracmemristor interpolating characteristics between the memristor and the ...

Semifluxons in Superconductivity and Cold Atomic Gases

, 2008
Josephson junctions and junction arrays are well studied devices in superconductivity. With external magnetic fields one can modulate the phase in a long junction and create traveling, solitonic waves of magnetic flux, called fluxons.

Research on Fractional-Order Sliding Mode Control of Fractional-Order Permanent Magnet Direct-Drive Wind Power System

Machines
A large number of practical systems show pronounced fractional-order features. In comparison with integer-order calculus, fractional-order calculus has been demonstrated to possess enhanced precision in the description of the dynamic behavior of complex ...

Linear and nonlinear capacitive coupling of electro-opto-mechanical photonic crystal cavities [PDF]

, 2014
We fabricate and characterize a microscale silicon electro-opto-mechanical system whose mechanical motion is coupled capacitively to an electrical circuit and optically via radiation pressure to a photonic crystal cavity.
