Strong and weak head-related transfer functions: The eHRTF analytical framework [PDF]

open access: yesJASA Express Letters
This article introduces an analytical framework for modeling head-related transfer functions (HRTFs) from a listener-centered perspective. The distinction between strong (or general) HRTFs, aiming for idealized physical acoustic fidelity, and weak (or ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Study of capabilities of hybrid scheme for advection terms approximation in mathematical models of compressible flows

open access: yesТруды Института системного программирования РАН, 2018
The hybrid method for approximation of advective terms is proposed in order to resolve flows in the wide Mach numbers region. This hybrid method is based on the Kurganov-Tadmor (KT) scheme and projection method PISO (Pressure Implicit with Splitting ...

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.

Investigation of the adequacy of the acoustic field model in the closed space [PDF]

open access: yes, 2013
In order to model the sound propagation as adequately as possible in the closed space and its interaction with obstacles, the assessment of several excitation sources and the sound transmission through the obstacle should be taken into account, which is ...
