The value of the ratio of central core radius to the normal artery radius in the unobstructed artery is generally taken as 0.95 [15].
Instead, they begin at an optimal, central, transition radius and radiate outward to the outer edge of the disk.
For this purpose, the influences of variation of the central ring radius, on the operating wavelength have been investigated.
The storm variables such as central pressure, radius of maximum wind, speed of forward motion and direction of storm movement were extracted and the method based on standard Hydromet pressure profile, were used for the hindcast of storm wind fields.
Sensitivity of the geometric parameter is from large to small as follows: thickness, central angle, radius and separation.
All cells recorded were obtained from the area of the cortex representing the central 10° (radius) of the visual field.
Other stimulus related factors, such as eccentricity or luminance level, have a significant but comparatively small effect on reaction time within the central 30°-radius visual field in healthy young individuals.
Methods: We used a specially designed video-campimetric device equipped with a continuous infrared (IR) pupillographic fixation control (Tübingen Computer Campimeter) and recorded reaction times upon presenting horizontally moving small circular stimuli (size 26′; constant angular velocity 2°/s) starting at 16 locations within the central 30°-radius of the visual field.
Since the maximum wind-speed radius, central pressure differential, latitude of typhoon center and even surface temperature of the ocean during typhoon process affect wind-pressure distribution coefficient β more or less, further study and verification are needed to determine the method for calculating β that gives the best precision for the radial atmospheric pressure distribution of a typhoon.
As the angleβ gradually changes the central bright core radius is changed inversely proportional to sinβ.
