Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Study on blind estimation of Speech Transmission Index in room acoustics [PDF]

open access: yes, 2011
Speech transmission index (STI) is one of the objective measurements that assess speech transmission quality in the room acoustics. This paper proposed a method for blindly estimatingSTI based on the concept of the modulation transferfunction (MTF).

An Experimental Study of Acoustic Comfort in Open Space Banks Based on Speech Intelligibility and Noise Annoyance Measures

open access: yesArchives of Acoustics, 2017
Tasks requiring intensive concentration are more vulnerable to noise than routine tasks. Due to the high mental workload of bank employees, this study aimed to evaluate acoustic comfort in open-space banks based on speech intelligibility and noise ...

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

open access: yesAdvanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Influence of artificial mouth’s directivity in determining Speech Transmission Index [PDF]

open access: yes, 2005
In room acoustics, one of the most used parameters for evaluating the speech intelligibility is the Speech Transmission Index (STI). The experimental evaluation of this STI generally employs an artificial speaker (binaural head) and listener ...

Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...
