The new focal length allows a horizontal angle of view of up to 82.4 degrees.
The limit periodic interval is 9.0 m, with the corresponding presplitting horizontal angle is 0[degrees].
Nakipoglu et al (2008)  have measured sacral horizontal angle (SHA) between the base of sacrum and the horizontal plane.
Moreover, the average of horizontal angle of the streamlines, vector, and locus of maximum velocity at different levels were subsequently determined and the results have been analyzed.
The drift of icebergs in the open ocean is typically largely determined by the balance of the forces illustrated here: drags exerted by surface winds and ocean currents (acting at a horizontal angle [phi] to each other), the Coriolis force associated with the iceberg's velocity, and the pressure gradient force associated with the sea surface slope, [theta].
Field survey involved collection of 9 disturbed samples and 5 undisturbed soil samples at depth of Im by box method.The topographic survey using Total Station was for slope distance, vertical angle, and horizontal angle from a setup point to a foresight point.
In addition, the site says&nbsp;users should not&nbsp;look all the way up or down because the app is limited to capturing the horizontal angle only; thus, the illusion of looking into a world in 360&nbsp;degrees wears thin on top and at the bottom.
To solve this problem, a method of visibility testing for 3D objects based on horizontal angle (HA) and Vertical Projection Angle (VPA) is proposed and the processing of Continuous Visible Range Query based on this visibility testing method is presented.
where [[phi].sub.n] = arctan([[increment of y].sub.n]/[[increment of x].sub.n]) denotes the horizontal angle between the BS antennas boresight and the nth user in the horizontal plane, and [[phi].sub.n] = arctan ([DELTA][z.sub.n]/[square root of [([[increment of x].sub.n]).sup.2] +[([[increment of y].sub.n]).sup.2]]) indicates the vertical angle between the horizon and the line connecting the BS to the nth user.
The control points are placed as they form four zenith-horizon lines at horizontal angle 0, 100, 200 and 300 grads respectively.
