SOUND TRAVELING-WAVES IN WIND INSTRUMENTS AS SOLUTIONS TO NON LINEAR NON HOMOGENEOUS GAS DYNAMICS EQUATIONS
, 905
"... Abstract. The sound propagation is usually described by a linear homogeneous wave equation, though the air flow in a duct is described by the gas dynamics equations, using a variable cross section, which corresponds to a non linear non homogneous system. The aim of this paper is to exhibit a common ..."

fullfills some condition which corresponds exactly to the general shape of the wind instruments. The conclusion is that in the wind intruments, the shape yields linearity. 1. The gas dynamics models with source terms The duct is supposed to have a cylindrical symetry along its axis which can be a straight
Sound Synthesis By Simulation Of Physical Models Of Musical Instruments
, 2003
"... Over the last decades, several powerful sound sythesis techniques have appeared on the consumer market. This is due to both the increased computation power of processors and the re-emergence of software-based synthesis. At the same time, the need for simple user interfaces to control complex intrume ..."

intrument models has become apparent. In this thesis, the digital waveguide technique is used to build models for wind and string instruments. These models allow the simple use of natural haptic interfaces for the measurement of the input parameters, without the need of complex parameter mapping.
A MULTI-SCALE PERSPECTIVE OF TRMM-LBA CONVECTION
"... Abstract-This study presents an overview of Amazonian convection from the perspective of both ground and satellite intrumentation, with particular emphasis on radar observations of two MCSs that occurred during the TRMM-LBA field campaign. The MCSs formed in different meteorological regimes, based ..."
