Fractal Dimensions and Singularities of the Weierstrass Type Functions
نویسنده
چکیده
A new type of fractal measures Xs 1 < s < 2, defined on the subsets of the graph of a continuous function is introduced. The J-dimension defined by this measure is 'closer' to the Hausdorff dimension than the other fractal dimensions in recent literatures. For the Weierstrass type functions defined by W(x) = A-aig(Aix), where A > 1, 0 < a < 1, and g is an almost periodic Lipschitz function of order greater than a, it is shown that the %-dimension of the graph of W equals to 2 a, this conclusion is also equivalent to certain rate of the local oscillation of the function. Some problems on the 'knot' points and the nondifferentiability of W are also discussed.

Fractal random series generated by Poisson-Voronoi tessellations
In this paper, we construct a new family of random series defined on R, indexed by one scaling parameter and two Hurst-like exponents. The model is close to TakagiKnopp functions, save for the fact that the underlying partitions of R are not the usual dyadic meshes but random Voronoi tessellations generated by Poisson point processes. This approach leads us to a continuous function whose random...
متن کاملPedotransfer functions for estimating soil moisture content using fractal parameters in Ardabil province
Extended abstract 1- Introduction Soil moisture curve is an important characteristic of soil and its measurement is necessary for determining soil available water content for plant, evapotranspiration and irrigation planning. Direct measurements of soil moisture coefficients are time-consuming and costly. But it is possible to estimate these characteristics from readily available soil propert...
متن کاملChains with Fractal Dispersion Law
Chains with long-range interactions are considered. The interactions are defined such that each nth particle interacts only with chain particles with the numbers n±a(m), where m = 1, 2, 3, ... and a(m) is an integer-valued function. Exponential type functions a(m) = b, where b = 2, 3, .., are discussed. The correspondent pseudodifferential equations of chain oscillations are obtained. Dispersio...

متن کاملThe Hausdorff Dimension of Graphs of Weierstrass Functions
The Weierstrass nowhere differentiable function, and functions constructed from similar infinite series, have been studied often as examples of functions whose graph is a fractal. Though there is a simple formula for the Hausdorff dimension of the graph which is widely accepted, it has not been rigorously proved to hold. We prove that if arbitrary phases are included in each term of the summati...
