Angular distance along the ecliptic from the vernal equinox eastward.
According to (8), if the
angular distance of a particle to the direction of the target is more than distance T, it will be multiplied by 0 and will not be used.
In Figure 7(c) the two peaks are not distinct due to the high noise in the signal (SNR = 5 dB) and a small
angular distance of the sources.
Further simulations with latitudes between 84[degrees]-89[degrees] N and a latitude
angular distance of 1[degrees] (Fig.
We can observe that: (a) MRT is minimal when cue-target distance is equal to 180[degrees] (259 ms); (b) MRT increases as cue-target
angular distance decreases and, (c) the magnitude of inhibition (MRT delay) is influenced not only by
angular distance between cue and target locations but also depends on whether cue and target are located in the same or in different quadrants.
c being the spherical
angular distance given by (3).
In conditions of heavy fog -- which will be our focus here -- only the rear lights of the vehicle in front are visible, and the distance to that vehicle is perceived on the basis of the visible characteristics of the car's lights: their angular size, their luminance, and the
angular distance between them (if there are two).
The two right spherical triangles and one spherical triangle of Fig 5 allow the calculation of the
angular distance from the roll axis and the target (j):
Even though the starlit bodies are separated by an
angular distance of just 70 arcseconds--a minuscule fraction of the width of the full moon as seen from Earth--the near-infrared sensor was so tiny that it could only record the infrared light from one galaxy at a time.
Horizontal positions are usually specified in one of two ways: 1) Latitude and Longitude, which specify the
angular distance from a reference point on the earth's surface taking into account the fact that the surface is curved; and 2) Rectangular or Cartesian coordinates, which specify the horizontal distances at right angles from a reference point and which ignore the curvature of the earth's surface.
The Helen Keller National Center Act of 1992 defines an individual who is deaf-blind as an individual "who has a central visual acuity of 20/200 or less in the better eye with corrective lenses, or a field defect such that the peripheral diameter of visual field subtends an
angular distance no greater than 20 degrees, or a progressive visualloss having a prognosis leading to one or both of these conditions; who has a chronic hearing impairment so severe that most speech cannot be understood with optimum amplification, or a progressive hearing loss having a prognosis leading to this condition; and for whom the combination of impairments ...
If B's distance from the earth can be determined, the increase in the
angular distance between A and B can be determined and, using the known time between the observations, B's transverse velocity can be calculated.
