ZEROES OF GENERALIZED FRESNEL COMPLEMENTARY INTEGRAL FUNCTIONS

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2016
Theoretical upper and lower bounds are established for zeroes of a parametric family of functions which are defined by integrals of the same type as the Fresnel complementary integral.

A Novel Gamma Distributed Random Variable (RV) Generation Method for Clutter Simulation with Non-Integral Shape Parameters

open access: yesSensors, 2020
Sea clutter simulation is a well-known research endeavour in radar detector analysis and design, and many approaches to it have been proposed in recent years, among which zero memory non-linear (ZMNL) and spherically invariant random process (SIRP) are ...

Temperature dependent developmental time for the larva stage of Aedes aegypti

open access: yesMathematical Biosciences and Engineering, 2022
We first verify that the time from the emergence of larva to the emergence of pupa (i.e., the duration of the larva stage) for Aedes aegypti is approximately gamma distributed, provided that the pupation process is successful.

Angular characteristics of multipath propagation in an indoor industrial environment

open access: yesIET Microwaves, Antennas & Propagation, 2021
The characteristics of multipath components (MPCs) are addressed in an industrial environment at 1.3 GHz by means of measurements with a multidimensional channel sounder.

Markov chain modeling of daily rainfall in Lay Gaint Woreda, South Gonder Zone, Ethiopia

open access: yesJournal of Degraded and Mining Lands Management, 2018
Information on seasonal Kiremet and seasonal Belg rainfall amount is important in the rain fed agriculture of Ethiopia since more than 85% of the population is dependent on agriculture particularly on rain fed farming practices.

Large Sample Comparison of Parameter Estimates in Gamma Raindrop Distributions

open access: yesAtmosphere, 2020
Raindrop size distributions have been characterized through the gamma family. Over the years, quite a few estimates of these gamma parameters have been proposed. The natural question for the practitioner, then, is what estimation procedure should be used.

On Generalized Gamma Distribution and Its Application to Survival Data

open access: yesInternational Journal of Statistics and Probability, 2019
The generalized gamma distribution is a continuous probability distribution with three parameters. It is a generalization of the two-parameter gamma distribution.

A New Family of Extended Lindley Models: Properties, Estimation and Applications

open access: yesMathematics, 2020
There are many proposed life models in the literature, based on Lindley distribution. In this paper, a unified approach is used to derive a general form for these life models.

The variance-gamma ratio distribution

open access: yesComptes Rendus. Mathématique, 2023
Let $X$ and $Y$ be independent variance-gamma random variables with zero location parameter; then the exact probability density function of the ratio $X/Y$ is derived.

Integrated assessment of crop productivity based on the food supply forecasting

open access: yesAgricultural Economics (AGRICECON), 2015
Climate change scenarios suggest that long periods without rainfall will occur in the future often causing instability of the agricultural products market.
