A Digital Synthesis Model of Double-Reed Wind Instruments [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2004
We present a real-time synthesis model for double-reed wind instruments based on a nonlinear physical model. One specificity of double-reed instruments, namely, the presence of a confined air jet in the embouchure, for which a physical model has been ...

Physical Modeling of the Ancient Greek Wind Musical Instrument Aulos: A Double-Reed Exciter Linked to an Acoustic Resonator [PDF]

open access: yesIEEE Access, 2021
We present a simulation method for the auralization of the ancient Greek double-reed wind instrument Aulos. The implementation is based on Digital Signal Processing and physical modeling techniques for the instrument’s two parts: the excitation ...

Quasistatic nonlinear characteristics of double-reed instruments [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2007
This article proposes a characterization of the double reed in quasistatic regimes. The nonlinear relation between the pressure drop, Δp, in the double reed and the volume flow crossing it, q, is measured for slow variations of these variables.

Biomass and methane yield of giant reed (Arundo donax L.) as affected by single and double annual harvest

open access: yesGCB Bioenergy, 2021
The replacement of silage maize with giant reed as energy crop has been proposed as a mean for reducing the need of irrigation water as well as monetary and environmental costs of cultivation.

Saving Reed Lands by Giving Economic Value to Reed [PDF]

open access: yesMires and Peat, 2014
Discussions about the need for renewable energy, the need for nature conservation, the need to double the world’s food production to eliminate hunger, the need to reduce carbon dioxide emission, and the wish to reduce dependency on dwindling oil ...

Factors influencing low incidence of double brooding in the Great Reed Warbler

open access: yesJournal of Ornithology, 2023
AbstractDouble brooding, the laying of a second clutch after successfully fledging young from a first nest in a season, is a common reproductive strategy among short-lived birds to increase annual breeding success. Nevertheless, there is widespread intra- and interspecific variation in the probability of producing a second clutch.

Re-Contemplating the Classification of Multiple Reeds

open access: yesAsian-European Music Research Journal, 2021
The 2011 Revision of the Hornbostel-Sachs Classification of Musical Instruments by the MIMO Consortium categorises the “reedpipes with double (or quadruple) reeds” (422.1) according to the number of pipes, bore shapes, and finger holes, as it does to ...

Cloning and characterization of a Phragmites australis phytochelatin synthase (PaPCS) and achieving Cd tolerance in tall fescue. [PDF]

open access: yesPLoS ONE, 2014
The production of phytochelatins (PCs) provides an important means for plants to achieve tolerance to cadmium (Cd) toxicity. A reed gene encoding PC synthase (PaPCS) was isolated and its function tested through its heterologous expression in a strain of ...

A new classification of wind instruments: Orofacial considerations

open access: yesJournal of Oral Biology and Craniofacial Research, 2019
Background/objective: Playing a wind instrument implies rhythmic jaw movements where the embouchure applies forces with different directions and intensities towards the orofacial structures.

Classification and Monitoring of Reed Belts Using Dual-Polarimetric TerraSAR-X Time Series

open access: yesRemote Sensing, 2016
Synthetic aperture radar polarimetry (PolSAR) and polarimetric decomposition techniques have proven to be useful tools for wetland mapping. In this study we classify reed belts and monitor their phenological changes at a natural lake in northeastern ...
