Architecture and School: an approach about physical and educational space in teaching processes/Arquitetura e Escola: uma abordagem do espaço físico educacional colaborador dos processos de ensino

open access: yesDiversitas Journal, 2020
Primary childhood education, as a social promoter, has required the elaboration of spaces in which everyone has access, and this has significantly altered the functioning of these institutions.

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 ...

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 ...

MODELING AND EXPERIMENTAL STUDY OF A FIBER OPTIC HYDROPHONE SENSING ELEMENT [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2014
A model of the fiber-optic hydrophone sensor is suggested. Hydrophone construction comprises a malleable core made of a polymeric material with regulated elastic properties to which the optical fiber is wound. The built-in module of Comsol Multiphysics

The bag-of-frames approach: a not so sufficient model for urban soundscapes [PDF]

open access: yes, 2015
The "bag-of-frames" approach (BOF), which encodes audio signals as the long-term statistical distribution of short-term spectral features, is commonly regarded as an effective and sufficient way to represent environmental sound recordings (soundscapes ...

Model of the acoustic path of a separate-combined optical-acoustic transducer

open access: yesНаучно-технический вестник информационных технологий, механики и оптики
Ultrasonic testing methods occupy one of the key positions in flaw detection, structurescopy, in assessing the strength characteristics of materials and the stress-strain state of products.

THE CALCULATION OF HUGONIOTS IN IONIC SOLIDS [PDF]

open access: yes, 2002
The authors demonstrate the quantitative prediction of Hugoniots for an ionic crystal (NaCl) using the shell model with the best available potentials. The calculations show that these shock wave data can be predicted quite accurately by relatively simple

The effect of signal-to-noise ratio value on the error in measuring acoustic emission parameters: statistical assessment

open access: yesНаучно-технический вестник информационных технологий, механики и оптики
Modern acoustic emission diagnostic systems and complexes are a sensitive tool for detecting developing defects at an early stage when monitoring the technical condition of objects under operational loads.
