Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

Advanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

Conversion efficiency of soliton Kerr combs

Optics Letters, 2021
We investigate the conversion efficiency (CE) of soliton modelocked Kerr frequency combs. Our analysis reveals three distinct scaling regimes of CE with the cavity free spectral range (FSR), which depends on the relative contributions of the coupling and propagation loss to the total cavity loss.

An efficient method for protocol conversion

Proceedings of Fourth International Conference on Computer Communications and Networks - IC3N'95, 2002
We propose an efficient algorithm for constructing optimized protocol converters to achieve interoperability between heterogeneous computer networks. This method first generates constraints from existing protocols and imposes them to channel specifications, which removes message sequences of the channel specifications that do not contribute to system ...
