Nonlinear vibration energy harvesting by intentional excitation of high-frequency dynamical instability
… linear oscillator (primary system) subjected impulsive loading. This primary system is coupled to a lightweight, damped oscillating attachment (nonlinear energy sink, NES) via a thin wire, which generates an essential geometric cubic sti ness nonlinearity. Various electromechanical coupling …

Theoretical and experimental studies of the dynamics and acoustics of forced ordered granular networks
… chain respond at integer multiples of the excitation period, and which correspond to local peaks of the maximum transmitted force at the chain’s right, fixed end. In between these resonances we detect local minima of the maximum transmitted forces corresponding to anti-resonances, where …

Tfdtlm: a New Computationally Efficient Frequency Domain Tlm Based on Transient Analysis Techniques
… is the computational efficiency, where a single impulsive excitation could yield information over a wide frequency range. Also, it may be more natural and realistic to model non linear and frequency dispersive properties in the time domain rather than in the frequency domain. However, in some …

Absorption and emission processes in organometal trihalide perovskites
… to state that the majority of band-edge optical excitations at room temperature are free carriers, as it happens in inorganic semiconductors. Whether photoexcitations result in bound or unbound electron-hole pairs is not a problem of minor importance, because the design of optoelectronic devices …
