- Entirely too long ago, I posted that I had a paper about data analysis
- using fractals, and that I would post the reference. Well, here it
- (finally!) is, if anyone is (still) interested:
-
- Turbulent Combustion Data Analysis Using Fractals, W. Strahle, AIAA
- paper 90-0729, 28th Aerospace Sciences Meeting, Jan. 1990.
-
- The abstract reads:
-
- This paper investigates several types of data analysis, based upon fractal
- geometry concepts, using time series generated in turbulent combustion
- research. The techniques are quite general and may be used for other
- turbulent flows. Investigated are the generalized fractal dimension,
- multifractal probability density function, fractal filtration, multifractal
- spectrum, and fractal interpolation and its possible connection with
- chaotic dynamics. It is concluded that several of the techniques are
- useful for a) new visual depiction of the data, b) discrimination of
- portions of data traces as noise-contaminated, c) separation of wanted and
- unwanted high or low frequency events, and d) interpolation between sparse
- data points in either short run time or low data acquisition rate situations.

- Sorry for the delay!
