Entire Solutions in Delayed Lattice Differential Equations with Monostable Nonlinearity

SIAM Journal on Mathematical Analysis, 2009
Summary: We consider the following delayed lattice differential equations: \[ u_n'(t)=D\sum_{i\in \mathbb Z\setminus \{0\}} I(i)[u_{n-i}(t)-u_n(t)]-du_(t)+\sum_{i\in \mathbb Z} J(i)b(u_{n-i}(t-\tau)),\tag{1.1} \] where \(D>0\) is a given constant, \(\tau\geq 0\), \(I(i)=I(-i)\geq 0\), \(J(i)=J(-i)\geq 0\), \(\sum_{i\in\mathbb Z\setminus\{0\}} I(i)=1\),

Spreading speeds and monostable waves in a reaction-diffusion model with nonlinear competition

Journal of Mathematical Analysis and Applications, 2022
The authors study the cooperative Lotka-Volterra system with nonlinear competition \begin{align*} u_t&=u_{xx}+(1-u)(a_1v^2-u) \\ v_t&=dv_{xx}+rv(1-v-a_2(1-u)^2) \quad \text{in }\mathbb{R}\times (0,\infty), \end{align*} where \(r\), \(d\), \(a_1\), \(a_2\) are positive constants satisfying \(a_1>1 ...

A nonlinear monostable filter for bipolar pulse signal detection

Mechanical Systems and Signal Processing, 2007
We investigate a nonlinear bistable system as a nonlinear filter for bipolar pulse signal detection. This nonlinear system usually shows the phenomenon of stochastic resonance (SR) by adding noise. To thoroughly discuss the detection performance of the nonlinear system, we tune the system parameters to obtain the optimal detection performance.

Uncertainty Analysis of Excitation Conditions on Performance of Nonlinear Monostable Energy Harvesters

International Journal of Structural Stability and Dynamics, 2019
Nonlinear energy harvesters were found to be sensitive to excitation conditions. In order to reveal the influence mechanism of the excitation condition on the energy harvesting performance, this paper presents an uncertainty analysis for nonlinear monostable energy harvesters (NMEHs).

Computational and Experimental Efficiency Investigation of Nonlinear Energy Harvesting Systems Based on Monostable and Bistable Piezoelectric Beams

ASME 2021 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, 2021
Abstract Piezoelectric energy harvesting from vibrating structures under nonlinear oscillations has been proved quite promising, with a large amount of scientific works focusing on the maximum energy harvested. However, the detailed dynamic response of an electromechanical coupled nonlinear vibrating system and the interaction between ...
