Dr. Gurmukh Singh of the Department of Computer and Information Sciences recently published a research article, “Multifractal detrended moving average analysis of particle density functions in relativistic nuclear collisions” in Physica A: Statistical Mechanics and its Applications.
The article was written in collaboration with Dr. A. Mukhopadhyay from North Bengal University located in Raja Rammohanpur, India. The research involved the collection, analysis and stimulation of two large data sets obtained from two important experiments conducted at two national and international labs, Brookhaven National Laboratory located in Long Island, New York, and the European Center of Nuclear Research in Geneva, Switzerland.
The research article focused on the investigation of a single particle and the density fluctuations of produced mesons in relativistic collisions induced by two heavy-ion beams of 28Si at 14.5A GeV and 32S at 200A GeV. A large number of multifractal parameters obtained from the data analysis of these two big data sets were systematically compared with the events simulated from the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model under similar boundary conditions.
Through the investigation it was observed that that the single particle density functions in both experiments concerning big data sets were multifractal in nature. The degree of multifractality in the simulated event samples was almost equivalent to the corresponding empirical data. The results found throughout this study were interesting because they differed significantly from data formerly reported by the same two big data sets.
Part of the work has also been published in the Proceedings of the 5th Joint Conference of the Upstate Chapters of the American Statistical Association (UP-STAT Conference 2016): Data Science, Statistical Practice, and Education held recently at Canisius College in Buffalo.
Dr. Singh is involved in two international collaborations and mentors junior and senior undergraduates working on research studies. Michael Lewis, a senior Computer and Information Sciences major, is studying under Singh. Mr. Lewis presented his work at the 18th Annual Student Research and Creativity Exposition and also has been selected to present at the Consortium for Computing Sciences in Colleges-Northeastern Region (CCSCNE-2016) at Hamilton College on April 30.
