For NaOH/0.3% ORS-41/1.2 g/L HPAM solutions,with decreasing NaOH concentration from 1.5% or 1.2% to 0.1%,the viscosity vz shear rate and the storage modulus vz oscillation frequency curves are shifted upwards,that is,their viscosity and viscoelasticity become higher.
The analysis of mechanical grain-size composition and grain-size parameter is emphasized, they are frequency curves, accumulative frequency curves, normal probability accumulative frequency curves, grain-size median, mean size, standard deviation, skewness, kurtosis.
The grain size parameter of 64 sediment samples obtained from MS-2000 Laser Grain Size Analyzer has been illustrated in the frequency curves, cumulative frequency curves on probability scale, and modal curves.
The probability plots showed two or three segments, the transetion points of which were 6φ and 8φ, were not matched with the lower "valley" points at the corresponding frequency curves, revealing that there existed some mixing between the sub-populations.
The computation process of the frequency factors,Φ p and K p used in hydrologic frequency analysis,is very complex. While ap-plying the GAMMAINV function of Excel,theΦ p and K p can be evaluated quickly and easily. By applying skillfully the schematics of Excel,Hazen probability paper is drawn,then the hydrologic frequency distribution curve.
It is shown that this proposed method can be used to extract the maximum frequency waveform precisely from the strong background noise and can be applied further to clinical vascular diseases diagnosis.
This approach was tested using simulated and clinical Doppler ultrasound signals together with other three methods. The relative error of maximum frequency waveform estimation using this method is 20 times smaller than the one using the traditional methods at most.
In the frequency domain, the Short Time Fourier Transform method for the extraction of spectrum parameters is given as an example, while the feature extraction of maximum frequency waveform from carotid arteries using wavelet transform is another example in transform domain.
Here the frequency curve shows the typical structure of a bifurcation problem, which is definitely not controlled by viscous effects but by instabilities of the interaction of flow and phase transition process.
Non-stationary signal denoising using Time-Frequency curve surface fitting
It was also first observed that the frequency curve of the sensor resulting from the reaction of IgM antigen and antibody undulated in the experiment.
Beforehand, the previously incomplete frequency curve in the presence of uptake inhibition was extended at the lower end.
This study investigated the effects of opiate receptor-specific agonists on reward and motor functions in either the accumbens core or shell, using the intracranial self-stimulation (ICSS) rate-frequency curve-shift method.
By displaying the change of signal energy on two dimensional time-frequency images based on time-frequency analysis, a new mathematical morphology method to distinguish target from nonlinear time-frequency curves is presented.
Analyzing conductance-frequency curves of metal-insulator-semiconductor structures subject to surface-potential fluctuations and
Overlapping of frequency curves in nonconservative systems
It is shown for a bilayer piezoelectric transducer that the reduced Young's modulus and the thermal diffusion coefficient of the experimental object can be found from the amplitude-frequency and phase-frequency curves.
Increasing the electron-phonon coupling constant λ affects the particle-hole polarization operator in two possible ways to weaken temperature dependence and to make flatter frequency curves.
