The eigenvalue analysis of the pendulum systems ranging from single pendulum to quintuple indicates that natural frequency increases with degree of freedom for equal mass and length of each pendulum in a MPS. The results show that the natural frequency of a distributed pendulum system is larger ...
or species, is the existence of differences among its members; and the first step in an enquiry into the possible effect of a selective process upon any character of a race must be an estimate of the frequency with which individuals, exhibiting any given degree of abnormality ...
Results convey that the resonant frequency declines with the rising thermal conductivity ratio and body size. For a heat-conducting cylinder contained inside a differentially heated square cavity at its middle, a numerical analysis of laminar convective flows is conducted out by Jami et al. [41],...
When the order of the derivatives and integrals are non-integers in the classical partial differential equations, then we have a new kind of differential equations called fractional differential equations (FPDEs). The importance of fractional differential equations comes from their wide applications in ...
The viscosity was measured against increasing shear rates from 0.1 to 100 s−1, and dynamic moduli were measured by oscillatory tests at 1 Hz frequency with increasing stresses from 100 to 104 Pa. Material characterizations The elemental composition of pre-treated ceramic platelets was ...
Natural characteristics of thin-wall pipe of the compressor under uniformly distributed pressure were presented in this paper based on a cylindrical shell model. In the traditional method, the beam model was usually used to analyze the pipe system. In ac
This gives a quarterly-frequency series of forecasts, although from the first to the fourth quarters the actual horizons are 4, 3, 6, and 5, and the target moves from the current to the next year's growth rate between the second and third quarters. An alternative solution is to take a...
We used the corneal signal as a template to remove the artifact and filtered out the high frequency components. Amplitude of the grating reversal response was measured as the peak-to-peak voltages in the VEP waveform between 0 and 100 ms. The natural grating acuity is typically defined in ...
Time sequence can be regarded as the superposition of different frequency components. High-pass filter is to separate the smooth sequence with certain change trend from the variable time sequence and divide the time sequence into the fluctuating cyclic component data and the smoothly changing trend ...
