Vibration Attenuation by Periodic Foundations
Vibration attenuation to horizontal propagating waves by using periodic foundations is investigation. Periodic structure theory is introduced to design a new type of isolation foundations, which has a special frequency band gaps (or ‘attenuation zones’) that can barrier waves/vibrations propagation. Materials usually used in civil engineering are used to fabric periodic foundations with the uni...
متن کاملBroadband Hybrid Wireless Broadband
Wireless access networks are evolving rapidly and hold the promise of significantly altering the landscape for broadband competition. In a companion paper, we explained why wireless networks are unlikely to converge toward the sort of broadband platform network exemplified by wired Next Generation Access Networks. In this paper we present in more detail the future architecture we see most likel...
متن کاملBroadband Vibration Energy Harvesting Techniques
The continuous reduction in power consumption of wireless sensing electronics has led to immense research interests in vibration energy harvesting techniques for self-powered devices. Currently, most vibration-based energy harvesters are designed as linear resonators that only work efficiently with limited bandwidth near their resonant frequencies. Unfortunately, in the vast majority of practic...
متن کاملGlobal attenuation of broadband noise fields using energy density control
The performance of the energy density control algorithm for controlling a broadband noise is evaluated in a one-dimensional enclosure. To avoid the noncausality problem of the control filter, which often happens in a frequency domain optimization, analyses presented in this paper are undertaken in the time domain. This approach provides the form of the causally constrained optimal controller. N...
متن کاملNonlinear Optimal Control Techniques for Vibration Attenuation Using Magnetostrictive Actuators
This paper addresses the development of a nonlinear control design for attenuating structural vibrations using magnetostrictive transducers operating in nonlinear and highly hysteretic operating regimes. We consider as a prototype a thin plate subjected to exogenous pressure waves and controlled via Terfenol-D transducers at the plate edges; however the methodology is sufficiently general to en...
