The range of simulations allows consideration of "under-merged" plumes with low plume cone angle and high plume

direction angle, or "over-merged" plumes with high plume cone angle and low plume

direction angle.

In this paper, a FOPI controller and a well-tuned conventional PI controller are applied to experimental setup of four-wheel skid-steering mobile robot for speed and

direction angle control, respectively.

A], [beta], [alpha], and [psi] represent the speed of the UVS, actual wind speed, the actual wind

direction angle between [V.

Let a be a point in R2 , and n(8) = ( cos(8), sin(8)) be a unit vector in R2 , where 8 is

direction angle.

However, the model requires precise equipment, and some useful propagation parameters cannot be obtained in the measure, such as direction of arrival, distribution of the

direction angle of arrival and angular spread.

The average bistatic NRCS results versus scattering angles from linear, CWM and Creamer (2) sea surfaces for indent angles of 0[degrees] and 60[degrees] in wind

direction angle of 45[degrees] are shown in Figures 5(a), (b) (wind speed of 3 m/s).

Two six-port networks are used to determine the beam

direction angle.

e] ([beta]) of wind pressure is expressed by wind

direction angle [beta].

Let us assume that connecting traverse passes via points P and Q that form a baseline (with

direction angle [[alpha].

Under the same initial phase of the excitation signal, but with different excitation amplitudes along the x and y directions, the results change both in

direction angle of the part motion and in covered distance towards the centre of the steady trajectory.
