The technique for obtaining the vertical electric field is based on its proportionality to the Doppler velocities of type 2 irregularities as detected by coherent radars.
The Doppler velocities of type II irregularities are proportional to Ez, as given in Eq. 3 (Cohen 1973; Reddy 1977): Ez = frac{{V_{rm DII} left({1 + {varPsi}_{0}} right)}}{{sin left({varTheta} right)}}frac{{B^{2}}}{H}, (3)where ({varTheta}) is the zenith angle of the radar beam and H is the horizontal component of the geomagnetic field.
As shown, some qualitatively new effects occur: the velocity of Rayleigh type waves can be not minimal between bending waves; wave decay takes place with oscillations; under some type of anisotropy, power flow can equal zero and can change the sign.
The profound effect of parameters like material gradients (piezoelectric, dielectric and elastic) and width of the layers, on the phase velocity of Love type wave are presented graphically.
In the study, we find that piezoelectric (PE) and dielectric (DE) coefficients have more influence on phase velocity of Love type wave in comparison to other elastic parameters which should be an essential factor to control the specific characteristics of the multiferroic waveguides of Piezo-materials.
We measured swimming velocity of both type of sperm and found no difference between sneakers and consorts (consort curvilinear velocity = 167.7 ± 36.9 μm/s, n = 6, 1421 cells; sneaker velocity = 167.1 ± 33.5 μm/s, n = 3, 619 cells; Mean ± SE, Student's t-test, P = 0.745).
In addition, the results presented in this study do not show significant differences in peak torques values recorded bilaterally in knee extensors and additionally in flexors in a group of healthy subjects (Table 1) while such a statistical difference exists in patients with 60 180 s−1 angular velocities, regardless of type of performed surgery (Tables 1, 2).
This is why the level-2 expression for the energy flux in the present study can indicate the direction of the group velocity of different types of waves, an issue we shall discuss in a future study.
It has been known that the expression of the flux in (27a) can indicate the direction of the group velocity of different types of waves, in particular, mid-latitude RWs and IGWs (Hoskins et al. 1983; Plumb 1986; Haynes 1988).
Due to character of the system and regulations in practice (civil engineering, aircraft design, etc). it can be used for determination of the lowest flow velocity of various types of instability onset.
