A physical method for measuring speech-transmission quality
TL;DR: In this paper, a physical method for measuring the quality of speech-transmission channels has been developed, which represents an extension of the Articulation Index (AI) concept, which was developed mainly to account for distortions in the frequency domain (noise, bandpass-limiting).

Liquid-Fuel Behavior in an Aeronautical Injector Submitted to Thermoacoustic Instabilities
Julien Apeloig,François-Xavier d’Herbigny,Frank Simon,Pierre Gajan,Mikael Orain,Sébastien Roux +5 more
TL;DR: In this paper, the role of the liquid phase in the thermo-acoustic coupling which subsequently leads to combustion instabilities was investigated on an actual multipoint spray injector geometry used in real aeronautical combustors.

Reson SeaBat 8125 backscatter data as a tool for seabed characterization (Central Mediterranean, Southern Italy): Results from different processing approaches
TL;DR: In this paper, the capability of Multi-Beam Echo Sounder (MBES) system data to distinguish different seabed types in a site in the Tyrrhenian Sea (Mediterranean) is evaluated; dataset used includes bathymetric data and backscatter intensity, with the support of sediment samples and scuba investigations.

Current State-of-the-Art and New Directions in Strategic Environmental Noise Mapping
TL;DR: Current state-of-the-art developments in how the strategic noise mapping (SNM) process has progressed at the EU level since the introduction of the Environmental Noise Directive (END) in 2002 are reviewed.
Journal ArticleDOI
Red shift, blue shift: investigating Doppler shifts, blubber thickness, and migration as explanations of seasonal variation in the tonality of Antarctic blue whale song.
TL;DR: Results from vessel-based recordings of Antarctic blue whales indicate that variation in peak-frequency between calls produced by an individual whale was greater than would be expected by the movement of the whale alone, and analysis of intra-annual frequency shift at Antarctic recording stations indicates that the Doppler effect is unlikely to fully explain the observations of intra/annual pattern in the frequency of Antarcticblue whale song.

Receptive fields, binocular interaction and functional architecture in the cat's visual cortex
David H. Hubel,Torsten N. Wiesel +1 more
TL;DR: This method is used to examine receptive fields of a more complex type and to make additional observations on binocular interaction and this approach is necessary in order to understand the behaviour of individual cells, but it fails to deal with the problem of the relationship of one cell to its neighbours.
Journal ArticleDOI
An algorithm for the machine calculation of complex Fourier series
J.W. Cooley,John W. Tukey +1 more
TL;DR: Good generalized these methods and gave elegant algorithms for which one class of applications is the calculation of Fourier series, applicable to certain problems in which one must multiply an N-vector by an N X N matrix which can be factored into m sparse matrices.
Journal ArticleDOI
The use of fast Fourier transform for the estimation of power spectra: A method based on time averaging over short, modified periodograms
TL;DR: In this article, the use of the fast Fourier transform in power spectrum analysis is described, and the method involves sectioning the record and averaging modified periodograms of the sections.

Finite Element Procedures
TL;DR: The Finite Element Method as mentioned in this paper is a method for linear analysis in solid and structural mechanics, and it has been used in many applications, such as heat transfer, field problems, and Incompressible Fluid Flows.

Fox,Rod Fujita,Dennis Heinemann,Hunter S. Lenihan,Elizabeth M. P. Madin,Matthew T. Perry,Elizabeth R. Selig,Elizabeth R. Selig,Mark Spalding,Robert S. Steneck,Reg Watson +21 more
TL;DR: This article developed an ecosystem-specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine ecosystems and found that no area is unaffected by human influence and that a large fraction (41%) is strongly affected by multiple drivers.
