The results proved that these methods serve as an effective tool for diagnosis.KEYWORDS: Fractal dimension, MATLAB, c-means clustering, freeman's chain code, Higuchi algorithm, Box- Counting, lacunarity, coarseness and complexity, K-NN classifier.Amrutha.M...
Other methodologies use the concept of Levy stable fractional motions to describe the evolution of a stock’s price, taking volatility into account (Kim et al.2019; Panas2001). Several studies have demonstrated that the fractal dimension is not the inverse of the self-similarity index (Fernández...
statistical time series (Gneiting et al2012; Sánchez-Granero et al.2008,2012a,b) where fractal dimension is correlated with the Hurst exponent (a fractal parameter of an economic process), which is frequently used in financial analysis to study long-memory effects in a series of stock prices...
(i.e., correlation decays as a power-law), meaning that present depends on past behavior32. Also, α is inversely related to a typical fractal dimension, so in this case, the value increases with increasing regularity (or decreasing complexity) in the time series. This software is also ...
(the head size), while Goñi et al. have suggested to take into account the values between 5 and 40% of the smallest Euclidean dimension of the object39. We estimated the smallest Euclidean dimension of the cortical ribbon segmentation by firstly computing its bounding box, i.e., the box...
is significantly lower than its embedding dimension. We show both analytically and experimentally that the fractal dimension, rather than the dimension of the space contain- ing the data set, is the real determinant of performance. In
the wakes emanating leeward of SFG is strictly a function of fractal grid dimension and downstream distance from the grid, where larger bars create bigger wakes that meet and interact further downstream from grid42. As a consequence,IT,EandU’rms,E/U∞increase withX/X*in the production region...
Once the ratio of the thin-film physical length scale to pixel dimension, i.e. r has been secured, the δ can then be determined using, δ= Yins n − Yins ×r (2) awchceurreatYeinδs is the instantaneous tip pixel coordinate and n is the total number of images processed. To ...
