In the case of Eq. (49) with directional thrust, it is evident that the same radius can be obtained in two modes: a low lift configuration with higher vertical thrust component, or a higher lift configuration and lower vertical thrust component, but also with a downward directed thrust, without changing the aircraft configuration.
A pulse of high-frequency sound is transmitted downward from a directional sound source usually mounted a meter or two above the bed.
When an electrode is directed downward into the cortex it picks up responses in individual units at successive depths; units having the same directional sensitivity are arranged in columns so that the receptive fields of successive neurons are similarly oriented.
But when a user puts enough force on the home button (more than just a standard click) it can extend to just a bit beyond the surface of the display, giving it leeway to move left, right, up and down and accept input on the x- and y- axis, as well as the z-axis (a downward press from above, the only directional input supported by the current home button design).
Therefore, only if the oil spot is sufficiently large can its movement be seen by satellite equipment such as SAR [3] or airborne visual tracking using observance geometry involving the direction of camera observation in various planes of light polarization in relation to the directional distribution of the downward solar light [4].
We found a directional asymmetry in vertical OKR; downward motion induced a smaller number of ETMs compared with the upward motion in our stimulation paradigm (Figure 6B).
The directional system is made sufficiently bottom-heavy (pendulous) to counteract the downward pull of the vertical component of the Earth's magnetic field, which would otherwise cause the system to tilt.
We found that in WT embryos, the intercalation directionality is not very prominent during doming, but a clear animal vegetal directional bias is established during early epiboly, with similar upward versus downward intercalation distribution along this axis.
Another issue is that current LEDs generally provide only "directional light" rather than a 360-degree glow, meaning they are better suited to downward facing streetlights and ceiling lights than to many lamp-type settings.
