Investigation about effect of high amounts of nitrogen and source of nutrition on winter triticale productivity was carried out in a stationary field trial in the Sumadija region, in Central Serbia.
Therefore, holding it in its place against a stationary field housing to give the required braking effect.
The bottom line is this: If you shoot for the stationary field, you run a high risk of coming up short, looking at a fence row, power line or other obstacle before you reach that stationary field.
where a(0,0) = 1, ([p.sub.1], [p.sub.2]) is the order of field, and x(m, n) is output of the model, and the driving input field, u(m, n), is a 2D white zero-mean stationary field having variance of [[sigma].sup.2.sub.u].

The position update for motion with control is P(t + [DELTA]t) -P(t) + [DELTA]t x f(P(t)) + [DELTA]t x u(t) for a stationary field f(*) and P(t + [DELTA]t) = P(t) + [DELTA]t x f(P(t), t) + [DELTA]t x u(t) for a nonstationary field f(*, *).
Now, how a harmonic source [PI]0 = [p.sub.0][e.sup.ikr]/r, pumping electromagnetic energy in the limited closed domain, can produce a stationary field? Leonhardt and Philbin [5] emphasize this fact, 'in order to maintain a stationary regime we must supplement the source by a drain at the image'.
When the eyes are fixed on the screen the discs appear faint and still, but when the patient shifts their gaze the stationary field appears to move with them in the same direction, rather than seeming to move in the opposite direction as would normally happen.
This system consists of a 3-phase stationary field generator which AC output is rectified by a group of rectifiers.
Stationary field is a field not changing with time (stable), to simplify calculations usually considered as one-dimensional.
Faria (electrical engineering, Instituto Superior Tecnico, Lisbon) focuses on the governing laws and concepts without delving too deeply into specialized areas, and provides students with a basic understanding of stationary field phenomena, slow time-varying fields and rapid time-varying fields.
