Level Crossing Analysis of Burgers Equation in 1+1 Dimensions
We investigate the average frequency of positive slope ,
crossing the velocity field in the Burgers equation.
The level crossing analysis in the inviscid limit and total number of positive
crossing of velocity field before creation of singularities are given. The main
goal of this paper is to show that this quantity, , is a good
measure for the fluctuations of velocity fields in the Burgers turbulence.Comment: 5 pages, 3 figure
Level Crossing Analysis of the Stock Markets
We investigate the average frequency of positive slope ,
crossing for the returns of market prices.
The method is based on stochastic processes which no scaling feature is
explicitly required. Using this method we define new quantity to quantify stage
of development and activity of stocks exchange. We compare the Tehran and
western stock markets and show that some stocks such as Tehran (TEPIX) and New
Zealand (NZX) stocks exchange are emerge, and also TEPIX is a non-active market
and financially motivated to absorb capital.Comment: 6 pages and 4 figure
