A New Regional Localization Method for Indoor Sound Source Based on Convolutional Neural Networks

IEEE Access, 2018
At present, the sound source localization methods based on microphone arrays can be roughly classified into three categories: the controllable beamforming technology based on a maximum output power, the high-resolution spectrogram estimation technique ...

Ferroelectric Dynamic‐Field‐Driven Nucleation and Growth Model for Predictive Materials‐To‐Circuit Co‐Design

Advanced Materials, EarlyView.
This study presents a compact dynamic‐field‐driven nucleation and growth (DFNG) model that captures ferroelectric switching behavior under arbitrary voltage waveforms. It enables extraction of time‐dependent domain wall velocity and growth dimensionality, which can then be extended to device‐level modeling.

Surround Sound for Large Audiences: What are the Problems?

, 2007
When replaying surround sound to large audiences it is inevitable that some people will not be in the ideal central listening position relative to the loudspeakers. As a result of this, their surround sound experience is degraded.

Identification and qualification method of moving noise sources for the maglev flight tunnel

Kongqi donglixue xuebao
The maglev flying wind tunnel is a novel conceptual aerodynamic testing facility operating on the "object-moving and wind-static" principle, which poses new challenges for the localization and evaluation of moving sound sources in acoustic testing.

Local Soundness for QBF Calculi

EasyChair Preprints, 2018
We develop new semantics for resolution-based calculi for Quantified Boolean Formulas, covering both the CDCL-derived calculi and the expansion-derived ones. The semantics is centred around the notion of a partial strategy for the universal player and allows us to show in a local, inference-by-inference manner that these calculi are sound.
