An Improved Array Steering Vector Estimation Method and Its Application in Speech Enhancement

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We propose a robust microphone array for speech enhancement and noise suppression. To overcome target signal cancellation problem of conventional beamformes caused by array imperfections or reverberation effects, the proposed method adopts arbitrary ...

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle

open access: yessteel research international, EarlyView.
Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training

open access: yesSymbolic Interaction, EarlyView.
We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...

A New Multichannel Microphone Technique for Effective Perspective Control

open access: yes, 2011
This paper introduces a new multichannel microphone technique that was designed to produce multiple listener perspectives. A listener perspective paradigm and the related spatial attributes are also proposed for the evaluation of spatial quality in ...

Using Microphone Arrays to Detect Moving Vehicle Velocity

open access: yesArchives of Acoustics, 2013
The noise of motor vehicles is one of the most important problems as regards to pollution on main roads. However, this unpleasant characteristic could be used to determine vehicle speed by external observers.

Laser-Based Command Injection Attacks on Voice-Controlled Microphone Arrays

open access: yesTransactions on Cryptographic Hardware and Embedded Systems
Voice-controlled (VC) systems, such as mobile phones and smart speakers, enable users to operate smart devices through voice commands. Previous works (e.g., LightCommands) show that attackers can trigger VC systems to respond to various audio commands ...
