Some remarks on bifurcation analysis of a nonlinear vibrating system excited by a shape memory alloy material (SMA)
(2011-10-01)
In this paper, the dynamical response of a coupled oscillator is investigated, taking in consideration the nonlinear behavior of a SMA spring coupling the two oscillators. Due to the nonlinear coupling terms, the system ...

The effect of the negative coupling parameter on the spectrum of a trapped Bose gas
(SPRINGER, 2010)
The interest in attractive Bose-Einstein Condensates arises due to the chemical instabilities generate when the number of trapped atoms is above a critical number. In this case, recombination process promotes the collapse ...
One-dimensional trapped atoms: critical coupling parameter and critical number of particles
(SPRINGER, 2010)
In this paper we consider the case of a Bose gas in low dimension in order to illustrate the applicability of a method that allows us to construct analytical relations, valid for a broad range of coupling parameters, for ...
The aquaponic principle—It is all about coupling
(2022-01-01)
The aquaponic principle is the coupling of animal aquaculture (e.g. fish) with plant production (e.g. vegetables) for saving resources. At present, various definitions of aquaponics exist, some bearing the risk of ...

Cramér-Rao bound for parameter estimation in sensor arrays with mutual coupling
(Institute Of Electrical And Electronics Engineers, 2013-04)
The mutual coupling effect in a sensor array must be taken into account, since it degrades significantly the performance of the well-known signal direction finding algorithms. In this work, we derived the Cramér-Rao bound ...
Structural dependence of magnetic exchange coupling parameters in transition-metal complexes
(Elsevier, 2013-02-05)
Magnetic exchange coupling parameters are routinely calculated within same structures for high- and low-spin states, neglecting structural relaxations and temperature effects present in measurements. To estimate these ...
