Absence of diffusion through fractal interface

Maksimenko, V.V.; Andreev, G.B. - In: Physica A: Statistical Mechanics and its Applications 300 (2001) 3, pp. 339-349

The diffusion of molecules through the fractal interface between two “transparent” media is considered. Such a surface … possesses unique properties—its volume has a finite value. It is shown that the effective diffusion coefficient is equal to zero …

Business cycles and monetary policy asymmetry: An investigation using Markov-switching models

Tan, Siow-Hooi; Habibullah, Muzafar Shah - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 297-306

This study assesses empirically the effects of monetary policy on four ASEAN economies in different states. The idea of asymmetry is being examined by using the relatively popular technique of non-linear modeling—Hamilton's Markov regime-switching model. The findings confirmed the existence of...

A local non-parametric model for trade sign inference

Blazejewski, Adam; Coggins, Richard - In: Physica A: Statistical Mechanics and its Applications 348 (2005) C, pp. 481-495

We investigate a regularity in market order submission strategies for 12 stocks with large market capitalization on the Australian Stock Exchange. The regularity is evidenced by a predictable relationship between the trade sign (trade initiator), size of the trade, and the contents of the limit...

Fractal structure with a typical scale

Anazawa, Masahiro; Ishikawa, Atushi; Suzuki, Tadao; … - In: Physica A: Statistical Mechanics and its Applications 335 (2004) 3, pp. 616-628

In order to understand the characteristics common to distributions which have both fractal and non-fractal scale … fractal and non-fractal regions, we take those of personal income and citation number of scientific papers. We show that these …

Fractals of forbidden words and approximating their box dimensions

Huang, Cheng-Xing; Peng, Shou-Li - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 2, pp. 703-716

This paper provides the construction of the fractals defined by more than two forbidden words. Some properties of the table structure in the Hao’s frame representation are emphasized because they are the key to drawing the fractals. The recurrence formula are not only used in the enumeration,...

A Monte Carlo method for simulating fractal surfaces

Zou, Mingqing; Yu, Boming; Feng, Yongjin; Xu, Peng - In: Physica A: Statistical Mechanics and its Applications 386 (2007) 1, pp. 176-186

A Monte Carlo method is presented for simulating rough surfaces with the fractal behavior. The simulation is based on … is related to the effects of scaling constant G and the fractal dimension D of the profile of rough surface. The larger …

Can randomness alone tune the fractal dimension?

Hassan, M.K; Kurths, J - In: Physica A: Statistical Mechanics and its Applications 315 (2002) 1, pp. 342-352

terms of fractal dimension, we show that the fractal dimension increases with increasing order and reaches its maximum value …
