Considering the uneven distribution of convergence angle of weld line, all of confluence angle datum of weld line was exported in text format, and its arithmetic mean was used as the final value of confluence angle.
The electron beam of certain energy or convergence angle results in a certain projection while the electron beam of a different energy or convergence angle results in a different projection.
The TEM features a quad lens condenser system that independently controls electron beam intensity (spot size) and convergence angle. With more versatility and functionality than ever before in a non-aberration corrected TEM, the system is easier to use.
As the convergence angle range of SF CORDIC is [0,[pi]/8], where [pi]/8 = 0392699 is represented as 16'b0001 1001 0010 0010, we only need deal with the 13 least significant bits of the angle.
The Barrow VOR/DME RWY 25 approach shows grid courses ("040[degrees] G") and a notice, "Grid courses are true polar courses and convergence angle factor shall not be applied." While we understand true course, what is a grid course?
In a conventional two-camera, 3D rig system, the convergence angle is changed by moving the lens and the entire camera.
In this mechanism, distance is computed by measuring the convergence angle formed by the lines-of-sight from ommatidia of the left and right eyes (Baldus 1926; Barros-Pita & Maldonado 1970; Wehner 1981; Bauer 1981, 1985; Kral 1999; Kral et al.
The MIT algorithm combines several measures of the environment, including lateral separation, longitudinal separation, other aircraft velocity, convergence angle, and other aircraft heading rate.
The effect of the SEMs finite depth of field was modeled by varying the convergence angle of the incident electron beam.
In this paper, these complications are avoided by discussing the SAR fundamentals in terms of the end-to-end convergence angle of the radiation transmitted to and received from the target, since this term determines the SAR focusing action, while rotational ISAR is discussed in terms of its phase excursion.
