Gradually truncated log-normal in USA publicly traded firm size distribution
Autor: Hari M. Gupta, Gabriel A. Queiroz, Daniela R. de Aguiar, José R. Campanha, Charu G. Raheja
Publikováno v: Physica A: Statistical Mechanics and its Applications. 375:643-650
We study the statistical distribution of firm size for USA and Brazilian publicly traded firms through the Zipf plot technique. Sale size is used to measure firm size. The Brazilian firm size distribution is given by a log-normal distribution without

POWER LAW DISTRIBUTION IN EDUCATION: EFFECT OF ECONOMICAL, TEACHING, AND STUDY CONDITIONS IN UNIVERSITY ENTRANCE EXAMINATION
Autor: Fábio Roberto Chavarette, José R. Campanha, Hari M. Gupta
Publikováno v: International Journal of Modern Physics C. 14:449-457
We studied the statistical distribution of student's performance, which is measured through their marks, in university entrance examination (Vestibular) of UNESP (Universidade Estadual Paulista) with respect to (i) period of study — day versus nigh

Tsallis statistics and gradually truncated Lévy flight—distribution of an economical index
Autor: Hari M. Gupta, José R. Campanha
Publikováno v: Physica A: Statistical Mechanics and its Applications. 309:381-387
Tsallis postulated a generalized form for entropy and give rise to a new statistics now known as Tsallis statistics. In the present work, we compare the Tsallis statistics with the gradually truncated Levy flight, and discuss the distribution of an e

POWER LAW DISTRIBUTION IN EDUCATION: UNIVERSITY ENTRANCE EXAMINATION
Autor: Hari M. Gupta, Jos E R. Campanha, Fernando Dagnoni Prado
Publikováno v: International Journal of Modern Physics C. 11:1273-1279
We studied the statistical distribution of candidate's performance which is measured through their marks in university entrance examination (Vestibular) of UNESP (Universidade Estadual Paulista) for years 1998, 1999, and 2000. All students are divide

The gradually truncated Lévy flight: stochastic process for complex systems
Autor: Hari M. Gupta, José R. Campanha
Publikováno v: Physica A: Statistical Mechanics and its Applications. 275:531-543
Power-law distributions, i.e. Levy flights have been observed in various economical, biological, and physical systems in high-frequency regime. These distributions can be successfully explained via gradually truncated Levy flight (GTLF). In general,

The gradually truncated Lévy flight for systems with power-law distributions
Autor: José R. Campanha, Hari M. Gupta
Publikováno v: Physica A: Statistical Mechanics and its Applications. 268:231-239
Power-law distributions have been observed in various economical and physical systems. Levy flights have infinite variance which discourage a physical approach. We introduce a class of stochastic processes, the “gradually truncated Levy flight” i

Integrated Services Digital Networks (ISDN): Structure and Services
Autor: Hari M Gupta
Publikováno v: IETE Journal of Education. 35:97-103
In this paper the concepts of ISDN are introduced. The need for ISDN and standard ISDN interfaces are described. It is followed by the description of the transmission structure. The ISDN services and users' view of these services have been presented.

Size limiting in Tsallis statistics
Autor: José R. Campanha, Hari M. Gupta, Sidney J. Schinaider
Power law scaling is observed in many physical, biological and socio-economical complex systems and is now considered as an important property of these systems. In general, power law exists in the central part of the distribution. It has deviations f
