(i) Angle of pitch [theta] is the intersection angle between the axis [O.sub.b][x.sub.b] and the plane [O.sub.0][x.sub.0][z.sub.0].

Figures 7 and 8 depict attitude (angle of pitch and yaw) and hydrodynamic (angle of attack and sideslip) angles during the sailing, respectively.

The dynamic process of the angle of yaw and angle of pitch is obtained by integrating the angular velocity in the y-axis and z-axis as shown in Figure 15.

Considering the case of sheath helix with each turn being isolated from the neighboring one, but still the helical winding being continuous, the dispersion behavior of fiber is analyzed under the variation of the angle of pitch of conducting helical twists, which is followed with the determination of energy flux density patterns in the waveguide structure.

We first focus on the evaluation of the propagation constants corresponding to the low-order hybrid modes in the guide using two extreme values of the angle of pitch, that is, 0[degrees] and 90[degrees].

Fibers with helical structures, which fall into the category of complex mediums, have also attracted investigators primarily because the angle of pitch of the helix in use exhibits dominant characteristics to alter the wave propagation characteristics of the guide.

Also, the introduced values of the angle of pitch are taken to be 0[degrees], 45[degrees] and 90[degrees].

The presence of helical windings at the core-inner clad boundary allows to control the flow of power through the guide by suitably adjusting the angle of pitch, which is effective in the outermost liquid crystal section as well.

Then there's a Shotgun Combo Gauge (used to measure length of pull, drop at comb,

angle of pitch and cast), the Boremaster (for measuring bore and choke dimensions, chamber length and diameter, forcing-cone length and dimensions and barrel-wall thickness), along with various fitted carrying cases and cleaning items.

This approach will make it possible to ensure motion with the increased

angle of pitch and velocity in the initial stage, which will lead to the quick AUV moving in the vertical plane.

Static flux (open circles) is very low when the blade is parallel to flow (lower than the small-angle values for either the plate or the flow-protected blade), but increases with increasingly positive

angle of pitch to values higher than those for the other models.

We find that making the

angle of pitch (of DB helix) as 90[degrees] greatly reduces the propagation of power, and therefore, a change in pitch wouldmake the guide to amplify or attenuate the signal depending upon lowering or increasing its value.
