We show that resonant coupling and entanglement between a mechanical resonator and Majorana bound states can be achieved via spin currents in a 1D quantum wire with strong spin-orbit interactions. The bound states induced by vibrating and stationary magnets can hybridize, thus resulting in spin-current induced 4π-periodic torques, as a function of the relative field angle, acting on the resonat...

The work investigates alternative capacitive sensing topologies for microelectromechanical systems, that simultaneously enable large quasi-stationary sensitivity, comparable to parallel-plates configuration, and large quality (Q) factor. In agreement with the model predictions, about 3-fold larger Q factor and 2-fold larger resonant sensitivity are obtained on the optimized geometry. © 2015 The...

We study the topology of Floquet states and time-averaged optical conductivity lattice model a thin topological insulator subject to circularly polarized light using extended Kubo formalism. Two driving regimes, off-resonant on-resonant, two models for occupation states, ideal mean-energy occupation, are considered. In real part DC Hall is shown be quantized while it not distribution. The trans...

An accurate model named as the Modified Wolff Model (MWM) is presented as an efficient CAD tool for determination of resonant frequency of the dominant and higher order modes under the multi-layer condition in thin and thick circular microstrip patch antennas. The effects of dielectric cover on the resonant frequency obtained from MWM have been compared against the result of theoretical method ...

This paper presents a new control approach for mitigating friction-induced vibration (FIV) issued from the mode-coupling mechanism. The key idea is to put friction system onto cascade of independent subsystems by using first-stage control. Then, second-stage defined and proven be much more efficient controlling both transient stationary regimes FIV. Asymptotic stabilization formally demonstrate...

Soft Switcing techniques have recently been applied in the design of dc-ac converters, in order to achive better performance, higher efficiency, and power density. One of the soft switching techniques uesd in inverters is resonant dc links. These topologies have some disadvantages such as irregular current peaks, large voltage peaks, uncotrollble pulse width, etc. Another soft switching method ...

The characteristics of subseasonal circulation variability over the South Pacific are examined using 10-day lowpass-filtered 700-hPa geopotential height NCEP–NCAR reanalysis data. The extent to which the variability in each season is characterized by recurrent geographically fixed circulation regimes and/or oscillatory behavior is determined. Two methods of analysis (a K-means cluster analysis ...

This paper presents a linear stability analysis of natural convection in a horizontal layer of a viscoelastic nanofluid. The Oldroyd B model was utilized to describe the rheological behavior of a viscoelastic nanofluid. The model used for the nanofluid incorporated the effects of Brownian motion and thermophoresis. The onset criterion for stationary and oscillatory convection was derived analyt...
