Inverse Generalized Gamma Distribution with it's properties [PDF]
المجلة العراقية للعلوم الاحصائية, 2020 : In this paper, we introduce a new life time distribution . This distribution based on the reciprocal of Generalized Gamma (GG) random variable . This new distribution is called the Inverse Generalized Gamma (IGG) Distribution in which some of the ...

Computing hypergeometric functions rigorously [PDF]
, 2016 We present an efficient implementation of hypergeometric functions in arbitrary-precision interval arithmetic. The functions ${}_0F_1$, ${}_1F_1$, ${}_2F_1$ and ${}_2F_0$ (or the Kummer $U$-function) are supported for unrestricted complex parameters and ...

The Clumpiness of Cold Dark Matter: Implications for the Annihilation Signal [PDF]
, 2002 We examine the expected signal from annihilation events in realistic cold dark matter halos. If the WIMP is a neutralino, with an annihilation cross-section predicted in minimal SUSY models for the lightest stable relic particle, the central cusps and ...

A note on polylogarithms and incomplete gamma function
, 2020 In this paper, we firstly introduce the polylogarithms and incomplete gamma function. Then, we claim that there is a relation between polylogarithms and a generalization of incomplete gamma function. Secondly, we give a formula related to polylogarithms.

Asymptotic Inversion of Incomplete Gamma Functions [PDF]
Mathematics of Computation, 1992 The normalized incomplete gamma functions are defined by \[ P(a,x)={1\over{\Gamma(a)}} \int_ a^ x t^{a-1} e^{-t}dt, \qquad Q(a,x)={1\over{\Gamma(a)}} \int_ x^{+\infty} t^{a-1} e^{-t} dt, \] where \(a>0\), \(x\geq 0\). The author is interested in the \(x\)-values that solves the following (equivalent) equations: \(P(a,x)=p\), \(Q(a,x)=q\), where \(a>0\)

Uniform asymptotics for the incomplete gamma functions starting from negative values of the parameters [PDF]
, 1996 We consider the asymptotic behavior of the incomplete gamma functions gamma(-a,-z) and Gamma(-a,-z) as a goes to infinity. Uniform expansions are needed to describe the transition area z~a in which case error functions are used as main approximants.

Investigation of charge sharing among electrode strips for a CdZnTe detector [PDF]
, 2001 We have investigated charge sharing among the anode strips of a CdZnTe (CZT) detector using a 30 micrometer collimated gamma-ray beam. We compared the laboratory measurements with the predictions from our modeling of the charge transport within the ...

Chemical Engineering CommunicationsWhen analyzing materials non-isothermally using the Arrhenius equation under linear heating, a temperature integration is necessary. While the frequency factor in this equation is typically assumed to be constant, it can actually vary with temperature ...

Unified Performance Analysis of Mixed Line of Sight RF-FSO Fixed Gain Dual-Hop Transmission Systems [PDF]
, 2014 In this work, we carry out a unified performance analysis of a dual-hop fixed gain relay system over asymmetric links composed of both radio-frequency (RF) and unified free-space optics (FSO) under the effect of pointing errors. The RF link is modeled by
