For 3D-MIMO systems with ZF receivers in RC-LN fading channel, the optimal BS antenna tilt angle [[theta].sup.*.sub.tilt] (regarding the lower bound) is the mean value of vertical angles of the N users, i.e., [[theta].sup.*.sub.tilt] [approximately equal to] [N.summation over (n=1)] [[phi].sub.n]/N.

Each laser is mounted at a specific vertical angle to a spinning head moving at a rate of 5 Hz to 15 Hz.

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.

So, again dragging your weary accomplice out to the shooting range, if he is 1.7m in height and appears in the reticle at a vertical angle of 10 mils, he should be 170m distant.

The vertical angle ([[theta].sub.V]) to the research boat position (GPS) or theodolite position (TH) can be calculated using the relationship using the distance from the position (D) and the theodolite station height (h):

An additional wire was positioned to determine the variation of the vertical angle, calculated by protractor.

ISLAMABAD -- MNA Sheikh Rasheed Ahmed's car was hit by a "stray bullet coming down from the sky" on Thursday night, which was at terminal end of its trajectory at a low velocity and came at a vertical angle, police investigation revealed on Friday.The bullet partially pierced the top sheet of the car's trunk and got stuck.

Soldiers get a more accurate aim-point that automatically adjusts for range, ammunition and vertical angle. The reticle wirelessly transmits to a semitransparent helmet-mounted display.

The RECON rangefinders w/VAC (Vertical Angle Compensation), use "Bracket" targeting technology for easy aiming, and the VAC technology incorporates and adjusts its ballistics compensation automatically for archery as well as firearms.

The accuracy of measurement is based on a proper performance of geodetic tasks using appropriate measuring instruments that must undergone metrological verification or calibration processes valid for all kinds of measurements, such as a flat and vertical angle or length, distance measurements or monitoring construction deformation.

The vertical angle of the tug line decreases horizontal tug power as shown in Fig.

The all-new Micro II from OptiLogic certainly fits the bowhunting bill thanks to an extremely small form factor and Vertical Angle Compensation technology.

Several studies have been done on the evaluation of electromagnetic fields due to lightning channel with the assumption that the lightning channel strikes the ground at a vertical angle [2].

King reasons that long casts not only allow for maximum water coverage, but at a horizontal rather than vertical angle, when he drags the rig along bottom, it hops over bumps, which really gets the tail of the worm dancing.

The other sources generally produce errors that are constant (because vertical angle does not change between measurements performed at different azimuths); therefore residuals from the mean of half the difference between front face and back face measurements are to be considered when determining odd orders from Eq.
