Impulse generator circuit formulas
Electrical Engineering, 1934With impulse voltage testing of electrical equipment becoming more widely used, it seems highly desirable to be able to calculate the circuit constants required to produce the desired test waves and to calculate the waves that any given circuit constants will give.

General impulsivity in binge-eating disorder
CNS Spectrums, 2020AbstractBackgroundThe nature and significance of impulse-control difficulties in binge-eating disorder (BED) are uncertain. Most emerging research has focused on food-specific rather than general impulsivity. The current study examines the clinical presentation of patients with BED categorized with and without clinical levels of general impulsivity ...

Heat generation by impulse ultrasound
Ultrasonics, 2004An original method allowing to get a system of nonlinear evolution equations for the interacting modes applies to a problem of the heat generation by non-periodic ultrasound, including impulse one. The basic idea and final equations for the thermoviscous plane flow are presented. The limit of periodic source is traced.

The Journal of the Acoustical Society of America, 1981
An acoustic impulse generator is disclosed for use in a fluid media for oceanographic, seismographic and related applications. The generator includes a housing with a piston slidably disposed therein and a passageway through which a rod attached to the piston moves. A firing chamber is attached to the housing for channeling a quantity of liquid through

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 ...

Generation of the nervous impulse and periodic oscillations
Biological Cybernetics, 1976Usually the models for the excitation and propagation of the nervous impulse are studied either in the space-clamp situation or on a model axon extended on both sides to infinity. Following Fitzhugh in the present paper the release of an impulse train at the axon hillock is studied within the scope of Fitzhugh's BVP model.

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.

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 ...
