The stochastic model is a random field. Case calculation showed that its solution can reflect the trend and range of concentration change at any point and add probability meaning to isoconcentration to show the random change of pollution zone under influences of different factors.
This paper presents the relationship of the main factors and noise level based on the Weighted Equivalent Continuous Perceived Noise Level(LWECPN) from the measurement data of the several typical airports.
Using these monomial bases we prove that the image of the transfer for a general linear group over a finite field is a principal ideal in the ring of invariants.
Using related sequences of Lucas numbers, other 3-manifolds are constructed, their geometric structures determined, and a curious relationship between the homology and the invariant trace-field examined.
We consider varieties over an algebraically closed field k of characteristicp>amp;gt;0.
LetG be a classical algebraic group defined over an algebraically closed field.
The kernel of a certain derivation of the polynomial ringk is shown to be nonfinitely generated overk (a field of charactersitic zero), thus giving a new counterexample to Hilbert's Fourteenth Problem.
This assumption is confirmed by an analysis of statistical data on the MVR for one of the Moscow airports.
This includes professional fire fighters, plant fire brigades (nuclear power plants, airports, chemical factories), governmental disaster relief organizations and the military.
Conditions for freezing precipitation at some airports of Russia and the CIS: IV.
A through flight is a type of connection that uses the same aircraft for the flights involved, which enables connecting passengers to remain onboard rather than deplaning to locate their departure gates at busy airports.
The transformation procedure is polynomial with respect to the number of airports and flights in the schedule.
