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].
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 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.
n]) denotes the horizontal angle between the BS antennas boresight and the nth user in the horizontal plane, and [[phi].
The control points are placed as they form four zenith-horizon lines at horizontal angle 0, 100, 200 and 300 grads respectively.
State-of-the-art EF11-24mm f/4L USM delivers unrivalled image quality and versatility in both wide-angle and close-up shots, covering horizontal angle of view at 117[degrees] and a diagonal angle of view of 126[degrees]
So, once Biggar's legs went above a horizontal angle - and slow motion replays showed 100% that they did - referee Jerome Garces was obliged to start with a red card and work down.
In CT-scan anteversion is measured as neck condylar angle (NC)=neck horizontal angle (NH)--condylar horizontal angle (CH) in neutral rotation of hip, or in internal rotation of hip measured as neck condylar angle (NC) =neck horizontal angle (NH) + condylar horizontal angle (CH).
If calibration of horizontal angle measures can be realized implementing different types of horizontal precise rotary tables (of different accuracy) available in industry, calibration of vertical angle measurements is a serious problem since very special instrumentation is needed for this task.
