When the insurance benefit of a last-survivor insurance product is payable at the moment of the last insured death, exploring continuous mortality models is essential to obtain the most appropriate premium and benefit reserve. In this study, Gamma-Gompert... see more

In this paper we study the moments of order statistics corresponding to a random sample of finite size from the three-parameter Gompertz-Makeham distribution. We will derive explicit closed-form formulas for the moment-generating function of order statist... see more

We study the uniform approximation of the sigmoid cut function by smooth sigmoid functions such as the logistic and the Gompertz functions. The limiting case of the interval-valued   step function is   discussed  using   Hausdorff metric.  Various express... see more

In the present work we discuss the?usage of the framework of chemical reaction networks for the construction of dynamical models and their mathematical analysis. To this end, the process of construction of reaction-network-based models via mass action kin... see more

Aim of this study is to make parametric modeling of the COVID-19 epidemic growth curve so that the maximum value and time at that point can be obtained from the cumulative cases of COVID-19. The data used in this study is the cumulative number of positive... see more

Various parameterizations of nonlinear models are common in the literature.In addition to complicating the understanding of these models, these parameterizations affect the nonlinearity measures and subsequently the inferences about the parameters. Bates ... see more

O presente trabalho teve como objetivo análise de micro-organismos patogênicos e deteriorantes (Salmonella, Sthaphylococcus coagulase positiva, Clostridium sulfito redutores, Coliformes a 45º C e bactérias láticas) em duas marcas de apresuntado e presunto... see more

El crecimiento de una especie, así como la concentración y extracción de nutrientes en el forraje, se pueden conocer a través de modelos matemáticos. Se utilizaron las ecuaciones de Gompertz y Logistic para estudiar el crecimiento, un modelo potencial neg... see more
