No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.

An approach for localizing abnormal sound sources in converter stations using mobile microphone arrays

open access: yesZhejiang dianli
The acoustic signals generated by power equipment such as converter transformers and AC filters tend to contain crucial status information. Traditional methods relying on manual auscultation to locate equipment faults suffer from subjectivity, low ...

Reflection-Aware Sound Source Localization

open access: yes, 2017
We present a novel, reflection-aware method for 3D sound localization in indoor environments. Unlike prior approaches, which are mainly based on continuous sound signals from a stationary source, our formulation is designed to localize the position ...

Subordination of related party claims in insolvency: A suggestive framework for Asian regimes

open access: yesInternational Insolvency Review, EarlyView.
Abstract Related party loans, due to their inherent nature, warrant a higher threshold for scrutiny when compared to loans extended by unrelated parties. Why were these monies advanced as loans, carrying higher priority in insolvency, rather than being invested as share capital?

Cochlear Implantation in Autoimmune Inner‐Ear Disease: Outcome and Patient‐Reported Benefit

open access: yesThe Laryngoscope, EarlyView.
This study demonstrates that patients with secondary autoimmune inner‐ear disease (AIED) achieve significant improvements in speech perception and quality of life following cochlear implantation. Although AIED patients may show slightly lower performance in noisy environments compared to controls, their subjective hearing benefit converges with matched

A Time Delay Estimation Method Based on Wavelet Transform and Speech Envelope for Distributed Microphone Arrays

open access: yesAdvances in Electrical and Computer Engineering, 2013
A time delay estimation method based on wavelet transform and speech envelope is proposed for distributed microphone arrays. This method first extracts the speech envelopes of the signals processed with multi-level discrete wavelet transform, and then ...

Has Ambisonics come of age? [PDF]

open access: yes, 2008
Ambisonics was developed in the 1970’s as a flexible, psycho-acoustically aware system1. Developed at the same time as Quadraphonics2, Ambisonics is an often mis-understood system that was far ahead of it’s time.

Multi‐Frequency Electrocochleography Results in Fewer Drop Alarms During Cochlear Implant Insertion

open access: yesThe Laryngoscope, EarlyView.
A novel multi‐frequency electrocochleography (ECochG) algorithm used during cochlear implant electrode insertion is associated with fewer drop alarms and an increase in optimal insertion track patterns. Multi‐frequency ECochG may provide a more accurate assessment of the cochlear microenvironment when compared to single‐frequency ECochG.

A machine learning assisted method for rapidly annotating benthic megafauna in large volumes of marine imagery

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Recent technological advancements have rapidly expanded our capacity for collecting image data in the marine environment, but processing images into meaningful ecological metrics remains a manual, time‐consuming, and biased process. This is particularly challenging with electro‐optical cabled imaging systems which generate images at a rate ...
