Stochastic Distribution

The basis of the Chou-Yang model is made up of a stochastic and non-stochastic distribution and has been successful in describing forward-backward multiplicities.[1] This project examines data drawn from CERN’s 7 TeV run where we revist the Chou-Yang model’s components. It also approaches phenomenological descriptions for cluster sizes from forward-backward multiplicaity correlation strength by the E735 collaboration.[6] For the stochastic binomial component, it examines the variance of the charge asymmetry parameter z with regards to fixed total charged multiplicities n. The fitting of the Generalized Multiplicity distribution along with the linear least square fitting of the forward backward multiplicity is analysed. The parameters for the Generalized Multiplicity Distribution is presented along with an investigation on the cluster size r.[3] This serves as an extention to the work done by W.Y Wang’sWeighted GMD model at7TeV, however the nonweighted GMD model is used here.[7]

Valid Time

We discuss first the valid time interval of a formula found in the literature which gives the theoretical distance run by a liquid which rises along a capillary tube as a function of time. A non-linear least square fitting of experimental data to this theoretical curve allows the measurement of the kinematic viscosity of the liquid. The goodness of the fitting for three different sets of experimental data given in the literature is above 99%.

In the present work, geodesic trajectories in Kerr-de Sitter geometry is used to fit the rotation curve of galaxies and estimate the values of mass M, Kerr parameter a, and cosmological constant  Ë. In this work, non-linear least square fitting of rotational velocity is used to estimate the some of the parameters. These estimates are mass in the range of (0.12±0.02) x1010 M to (70.37±11.26) x1010 M, the Kerr parameter in the range of  (0.7044±0.1127) to (0.9990±0.1598), and the cosmological constant in the range  of (1.790±0.286) x10-49 km-2 to (7.523±1.204) x10-42 km-2 for positive value of Ë while - (3.983±0.637) x10-41 km-2 to - (1.860±0.298) x10-42km-2 for negative value of Ë. The negative Ë values are found only for some galaxies with large recessional velocity. This suggests that the transition from anti-de-Sitter to de-Sitter phase with the deposition of vacuum energy may have occurred between the formation of these different galaxies.

Good Agreement

The real and imaginary part of complex dielectric constant for InAs(001) by adsorption of oxsagen atoms has been calculated, using numerical analysis method (non-linear least square fitting). As a result a mathematical model built-up and the final result show a fairly good agreement with other genuine published works.
