Simulations of a mortality plateau in the sexual Penna model for biological ageing [PDF]

, 2005
The Penna model is a strategy to simulate the genetic dynamics of age-structured populations, in which the individuals genomes are represented by bit-strings.

Comparative Study with Applications for Gompertz Models under Competing Risks and Generalized Hybrid Censoring Schemes

Axioms, 2023
In reliability and survival analysis, the time-to-failure data play an important role in the development of the reliability and life characteristics of the products. In some cases, these kinds of data are modeled using a competing risks model.

Constraining properties of GRB magnetar central engines using the observed plateau luminosity and duration correlation [PDF]

, 2014
An intrinsic correlation has been identified between the luminosity and duration of plateaus in the X-ray afterglows of Gamma-Ray Bursts (GRBs; Dainotti et al. 2008), suggesting a central engine origin.

Modelling the lactation curve of dairy cows using the differentials of growth functions [PDF]

, 2008
Descriptions of entire lactations were investigated using six mathematical equations. comprising the differentials of four growth functions (logistic. Gompertz, Schumacher and Morgan) and two other equations (Wood and Dijkstra).

New Modified Gompertz Probability Distribution With Flexible Hazard Functions

Journal of Probability and Statistics
This paper introduces a new probability model called the modified Gompertz distribution from the base Gompertz distribution by combining its hazard function with first and second degree polynomial (linear and quadratic) functions.

The Modified Beta Gompertz Distribution: Theory and Applications

Mathematics, 2018
In this paper, we introduce a new continuous probability distribution with five parameters called the modified beta Gompertz distribution. It is derived from the modified beta generator proposed by Nadarajah, Teimouri and Shih (2014) and the Gompertz ...

Evidence for the Gompertz Curve in the Income Distribution of Brazil 1978-2005

, 2008
This work presents an empirical study of the evolution of the personal income distribution in Brazil. Yearly samples available from 1978 to 2005 were studied and evidence was found that the complementary cumulative distribution of personal income for 99%

Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

[0,1] Truncated Exponential Marshall-Olkin-Gompertz Distribution: Properties and Applications

Tikrit Journal of Administrative and Economic Sciences, 2020
In this paper, a new compound distribution termed as [0,1]Truncated Exponential Marshall-Olkin-Gompertz (TEMO-Go)is introduced. Several essential statistical properties of TEMO-Go distribution were studied.
