The same hydrograph is generated 15 times and the mean values are found by calculating the average of all hydrographs. The time varying mean is obtained by using FFT, moving average, wavelet and EMD methods. The best time varying mean is selected according to prescribed criteria. Then, the 15 time series are processed and the stream-wise and transversal turbulence intensities are obtained. The mean of the product of fluctuations is also determined. © 2010 Academic Journals.Conference Object Citation - WoS: 2Citation - Scopus: 4Symbolic Computation of Petri Nets(Springer, 2007) Iglesias, Andres; Kapçak, SinanPetri nets are receiving increasing attention from the scientific community during the last few years. They provide the users with a powerful formalism for describing and analyzing a variety of information processing systems such as finite-state machines, concurrent systems, multiprocessors and parallel computation, formal languages, communication protocols, etc. Although the mathematical theory of Petri nets has been intensively analyzed from several points of view, the symbolic computation of these nets is still a challenge, particularly for general-purpose computer algebra systems (CAS). In this paper, a new Mathematica package for dealing with some Petri nets is introduced.
