If the Ricci tensor of a n([greater than or equal to] 3)-dimensional compact Riemannian manifold, (M,g), is negative semi-definite everywhere and negative definite at some p [member of] M, then (M,g) admits no orthogonally conformal vector field.
According to the ISO 14242, the femoral ball head in the Simulator is placed at the cross-section point of the three orthogonally related rotational axes with the specified ranges of the angular motions; the accuracy of reproducing is [+ or -] 3[degrees] at the maxima and minima of the motion and [+ or -] 1% of the cycle time for phasing.
Magnetic field components [H.sub.x], [H.sub.y], [H.sub.z] can be measured experimentally using orthogonally oriented magnetic sensors and compared with calculating results given from
The trait adjectives were selected such that the breadth and valence of the trait varied orthogonally. Explicit attitudes were assessed using semantic differential, feeling thermometer and rating scale measures.
The sanitary napkin has a longitudinal centerline and an orthogonally located lateral centerline, which make up longitudinal and lateral directions, respectively.
For example, the ratio of the orthogonally polarized LP components shown for the CP horn is [1.015e.sup.j1.489] at the angle of maximum radiation (0.13 dB amplitude difference and 85[degrees] phase difference), corresponding to a measured axial ratio of 0.72 dB.
Although the workstations are arranged orthogonally, the overall impression is of fluid informality.
Thoracic eye rhabdoms are described as lacking the orthogonally orientated layers of microvilli typical of rhabdoms in other Crustacea, and they often contain irregular arrays of microvilli - some of which may be expanded to form vesicles within the rhabdom (Van Dover et al., 1989; O'Neill et al., 1995; Nuckley et al., 1996; Kuenzler et al., 1997).
Two separate comb drives linked to dedicated connecting rods are micromachined orthogonally on a silicon wafer.
In the amplitude measurements, two sets of antennas with dipole-type patterns (loops or Adcock antennas) are arranged orthogonally. Signals arriving at the two antennas induce a voltage relative to the polarization and radiation pattern for each antenna.
