Accurate energy spectrum for power-law potentials with trigonometric basis: The optimal length
Accurate energy spectrum power-law potentials trigonometric basis optimal length
2010/11/11
We propose an optimal length for accurate calculation of eigenvalues and eigenfunctions of power-law potentials with trigonometric basis functions. We show that, this proposal make us free from using ...
The Anderson-Darling test of fit for the power law distribution from left censored samples
Power law distribution Complexity Goodness-of-fit EDFbased tests Anderson-Darling Asymptotic distributions Type II censoring Maximum likelihood estimation
2010/4/28
Maximum likelihood estimation and a test of fit based on the Anderson-Darling statistic is presented for the case of the power law distribution when the parameters are estimated from a left-censored ...
Fitting the Log Periodic Power Law to financial crashes: a critical analysis
Log Periodic Power Law financial crashes critical analysis
2010/4/27
A number of papers claim that a Log Periodic Power Law (LPPL) fitted to financial market bubbles that precede large market falls or 'crashes', contain parameters that are confined within certain range...
Point Processes Modeling of Time Series Exhibiting Power-Law Statistics
point processes 1/fnoise stochastic differentiale quations power-law distributions
2010/4/27
We consider stochastic point processes generating time series exhibiting power laws of spectrum and distribution density (Phys. Rev. E 71, 051105 (2005)) and apply them for modeling the trading activi...
Generating more realistic complex networks from power-law distribution of fitness
Power-law Scale-free networks Complex networks Fitness model
2010/7/5
In this work we analyze the implications of using a power law distribution of vertice’s quality in the growth dynamics of a network studied by Bianconi and Barab´asi. Using this suggested distri...

Hamilton-Jacobi Approach for Power-Law Potentials
Hamilton-Jacobi equation Power-law potentials
2010/10/13
The classical and relativistic Hamilton-Jacobi approach is applied to the one-dimensional homogeneous potential, V(q) = aqn, where a and n are continuously varying parameters. In the non-relativistic ...
Power-Law Distributions for the Citation Index of Scientific Publications and Scientists
Power-Law Distributions the Citation Index Scientific Publications and Scientists
2010/10/15
The number of citations of a scientific publication or of an individual scientist has become an important factor of quality assessment in science. We report a study of the statistical distribution of ...
