cutoff
Let Γ be a smooth compact convex planar curve with arc length dm and let dσ=ψ dm where ψ is a cutoff function.
      
The short-wave cutoff boundary of the capillary wave spectrum is established.
      
Thus, as the particle concentration increases, the central jump in compression [shock wave] moves in the direction of the nozzle cutoff, while the Mach number on the axis of the jet in front of the forward jump diminishes.
      
The results of an experimental study of a flow of rarefied gas of density ~10-5 g/cm3 beyond the cutoff of a hypersonic nozzle (M?11) by means of an electron beam with energy up to 43 keV are presented.
      
A study is made of the propagation of three-dimensional acoustic perturbations in a two-dimensional gas flow in axisymmetric channels of variable cross sectional area at frequencies near the cutoff frequency.
      
The dissociating molecules are simulated by cutoff harmonic oscillators.
      
Role of two-dimensional acoustic wave cutoff in the instability of subsonic MHD flows
      
High-frequency pulse generators based on SOS diodes with subnanosecond current cutoff time
      
The output power-amplification unit is based on an inductive storage and SOS diodes with subnanosecond current cutoff time.
      
Physical processes in the semiconductor structure of a SOS diode operating in the subnanosecond current cutoff mode are considered.
      
Daily aerosol samples (3500 m3/d) were collected onto glass-fiber filters with an aerosol sampler having an aerodynamic cutoff diameter of 10-15 μm depending on the wind speed.
      
It is shown that monolithic current amplifiers with collector-base cross coupling can ensure a single-stage amplification up to 40 dB in the frequency range from 0 to 0.1fc (wherefc is the cutoff frequency of the transistors).
      
Transistors based on such nonuniform structures may have the cutoff frequency of 1000 GHz or even higher.
      
Instead of the cutoff wavelength, which is proportional to the length of the specimen, the definition involves the radial wavelength, which can be evaluated by applying the Fourier transform to the SPM micrograph [1].
      
A new approach is proposed to the design of high-order switched-capacitor LPFs of megahertz cutoff frequency for communications channel selection.
      
A fifth-order Chebyshev LPF with a 1-MHz cutoff frequency is thus synthesized and fabricated in a 0.35-μm CMOS technology.
      
The LPF consumes less than 10 mW from a 3-V power supply and exhibits a third harmonic distortion better than -54 dB in response to a 1-V sinusoidal input at the cutoff frequency.
      
It is shown that the use of membranes with an average pore size higher than the cutoff diameter for the particles to be removed from the suspension will be profitable only for the first 15-20 min of operation.
      
The decay behavior is determined by the minimum frequency of these traveling waves (because it must be higher than the cutoff frequency).
      
The frequency separating these spectral regions is determined as the cutoff frequency of the coherence function and is directly related to the component of the current in the direction perpendicular to that of signal propagation.
