Permutation decoding the binary images of certain double-parity reed-solomon codes
2010 IEEE International Symposium on Information Theory, 2010We introduce two permutation decoder designs for the binary images of double-parity [n, n − 2, 3] Reed-Solomon (RS) codes over binary extension fields F 2 m. The codes considered are limited to have zeros {1, α}, where α is any primitive element in F 2 m.

Flow regimes at the output of oboe double-reeds
The Journal of the Acoustical Society of America, 2006Measurements of the quasistatic nonlinear characteristic curve for double reeds show systematic deviations from an elementary model of a reed instrument based on a spring model associated to a Bernoulli flow input into the reed. These deviations were previously explained by the pressure recovered by the flow as it expands in the conically divergent ...

The Double-Reed Aerophone in India
Yearbook of the International Folk Music Council, 1975A recent article by Jairazbhoy in Ethnomusicology is perhaps the first cogent account of the oboe in India. Here I wish to offer a few comments on his paper and give some supplementary material and ideas.

The Burmese Double-Reed "Nhai"
Asian Music, 1971According to several informants the small nhai has only been used in its present form for about 25 years. Before this, they say, there was one pitched only a fourth above the large nhai, and this is the type described by U Khin Zaw in his article "Burmese Music"2 written about 1940.

Double-peak in the dissipation of NbSe2 vibrating reeds
Physica C: Superconductivity, 1992Vibrating reed (VR) and electrical resistance measurements were performed on single-crystal NbSe2 with hexagonal c-axis approximately parallel or perpendicular to an applied magnetic field, H. Field-cooling data revealed two peaks in the reed dissipation, 1/Q.

Prevalence of Medical Problems among Double Reed Performers
Medical Problems of Performing Artists, 2001One aspect of double reed performance warranting consideration involves the biomechanical stress placed on the human body through the performance of these instruments. At present, inadequate information exists that can effectively answer questions regarding the types of physical problems experienced by oboe and bassoon players and the percentages of ...

Aspects of vibrato and micromodulation in double reed instrument sounds
The Journal of the Acoustical Society of America, 2008The perceived naturalness of real and synthesized oboe and bassoon vibrato sounds has been investigated in several perception experiments. The stimuli were generated by means of a currently developed synthesis and analysis framework for wind instrument sounds (first presented at 152nd ASA meeting), based on the pulse forming theory.

Period doubling in free reeds coupled to pipe resonators
The Journal of the Acoustical Society of America, 2004An earlier study investigated behavior of the reed–pipe combination consisting of an American organ reed installed at the closed end of a cylindrical pipe. Over a wide range of pipe lengths and playing pressures, the sounding frequency is slightly below a pipe resonance frequency and can be pulled considerably below the natural frequency of the reed ...
