Foodborne infections are a significant cause of morbidity and mortality in human populations. Risk assessment and public health control measures could be greatly enhanced by establishing an accurate relationship between ingested dose and infection probability, and defining minimum infectious doses. In this paper, a novel neural network model is proposed for dose–response of foodborne pathogens....

Rameshwar D. Gupta was the speaker of a seminar titled “Generalized Exponential Distributions”. Gupta received his PhD degree in statistics from Dalhousie University in 1973. He worked in the University of the West Indies, University of Saskatchewan. He joined the University of New Brunswick in 1980. He has received the Merit Award at the University of New Brunswick at Saint John four times. Pr...

For the space of gamma distributions with Fisher metric and exponential connections, natural coordinate systems, potential functions and an affine immersion in R3 are provided.

Fuzziness is ever presented in real life decision making problems. In this paper, we adapt the pessimistic approach tostudy a pair of linear primal-dual problem under intuitionistic fuzzy (I-fuzzy) environment and prove certain dualityresults. We generate the duality results using exponential membership and non-membership functions to represent thedecision maker’s satisfaction and dissatisfacti...

We propose a dynamic program to find the shortest path in a network having gamma probability distributions as arc lengths. Two operators of sum and comparison need to be adapted for the proposed dynamic program. Convolution approach is used to sum two gamma probability distributions being employed in the dynamic program.

Abstract We discuss estimating the probability that sum of nonnegative independent and identically distributed random variables falls below a given threshold, i.e., $$\mathbb {P}(\sum _{i=1}^{N}{X_i} \le \gamma )$$ P ( ∑ i = <mml...

In a recent paper in this journal, Gautschi et al. [W. Gautschi, F.E. Harris, N.M. Temme, Expansions of the exponential integral in incomplete Gamma functions, Appl. Math. Lett. 16 (2003) 1095–1099] presented an interesting expansion formula for the exponential integral E1(z) in a series of the incomplete Gamma function γ (α, z). Their investigation was motivated by a search for better methods ...
