The Journal of the Acoustical Society of America, 1982
Apparatus for controlling a release of pressurized fluid, to generate an acoustic or shock wave impulse for use in underwater reflection seismic surveys. Compressed air is supplied to the acoustic impulse generator and is used both to provide the compressed air acoustic impulse and to retain two piston members in sealing engagement with each other to ...

Journal of Scientific Instruments, 1938
This paper describes a thyratron circuit for the production of voltage impulses of rectangular wave form whose time of duration and frequency can be varied over a wide range. The frequency range is 4-200 impulses per sec. and the time of duration of the impulse is variable from 3 to 100 per cent of the time of a complete cycle. The maximum value of the

Impulse Product Parameter in Landslide Generated Impulse Waves
Journal of Waterway, Port, Coastal, and Ocean Engineering, 2010Subaerial landslide generated impulse waves were investigated in a prismatic wave channel based on Froude similitude and granular slide material. The tests included the following seven governing parameters: still water depth, slide impact velocity, slide thickness, bulk slide volume, bulk slide density, slide impact angle, and grain diameter.

Generalities for Impulsive Systems
2019Necessary definitions and theorems, concerning differential equations with impulses at fixed moments, are introduced for the reader to be ready for comprehension of the main body of the book. This is, first of all, a description of piecewise continuous functions and their points of discontinuity.

The mechanism of impulse generation in excitable cells
Kybernetik, 1974Auf der Grundlage eines verallgemeinerten Membranmodelles fur den Ionentransport wird eine Beziehung zwischen Ionenleitwert und Membranpotential als modellmasige Bedingung fur die Impulsauslosung definiert. Hierdurch ist es moglich, die Impulsform und die Umsetzungskennlinie zwischen Eingangssignal und abgegebener Impulsfrequenz fur verschiedene ...

Singularly impulsive or generalized impulsive dynamical systems: Lyapunov and asymptotic stability
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004In this paper we present singularly impulsive or generalized impulsive dynamical systems. Dynamics of this system is characterized by the set of differential, difference, and algebraic equations. They represent the class of hybrid systems, where algebraic equations represent constraints that differential and difference equations need to satisfy ...
