Extended incomplete gamma functions with applications

Journal of Mathematical Analysis and Applications, 2002
In this paper the authors introduce the following functions \[ \gamma (\alpha,x; b,\beta)= \int^x_0 t^{\alpha-1} e^{-t-bt^{-\beta}} dt,\;x\geq 0,\;b\geq 0, \] and \[ \Gamma (\alpha,x;b, \beta)=\int^\infty_x t^{\alpha-1} e^{-t-bt^{-\beta}}dt,\;x\geq 0,\;b\geq 0, \] and call them extended incomplete gamma functions.

Clinical Outcomes of SEEG‐Guided Radiofrequency Thermocoagulation in Children With Focal Drug‐Resistant Epilepsy: A Multicenter Real‐World Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Stereoelectroencephalography‐guided radiofrequency thermocoagulation (SEEG‐RFTC) has emerged as a safe and effective minimally invasive treatment for children with drug‐resistant focal epilepsy. Although evidence from real‐world studies remains limited, numerous pediatric cases have demonstrated promising outcomes. This retrospective

The Gamma-Weibull-G Family of Distributions with Applications

Austrian Journal of Statistics, 2018
Weibull distribution and its extended families has been widely studied in lifetime applications. Based on the Weibull-G family of distributions and the exponentiated Weibull distribution, we study in detail this new class of distributions, namely, Gamma ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

A gamma type distribution involving a confluent hypergeometric function of the second kind

Revista Técnica de la Facultad de Ingeniería, 2012
In the present work a new gamma type distribution is obtained which involves a confluent hypergeometric function of the second kind. A generalized form of the incomplete gamma function and its complementary are introduced to obtain some statistical ...

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...
