Rice-field rat (Rattus argentiventer) is a rodent that has a high level of productivity. These animals attack rice plants from the vegetative to the generative phase. This research aimed to analyze and to predict the accuracy of the use of owls with mathe... see more

The purpose of this paper is to investigate several context-free grammars suggested by the Lotka-Volterra system. Some combinatorial arrays, involving the Stirling numbers of the second kind and Eulerian numbers, are generated by these context-free g... see more

Both fixed and mobile broadband technologies are adopted in Indonesia. This study aims to identify the competition model between both of them. Non-linear exponential model is employed to estimate diffusion pattern of both broadband services. Meanwhile, Lo... see more

A perturbed non-autonomous Lotka Volterra model with a diffusive term is considered. Conditions assuring non linear stability of a biological critical point are obtained also in the case in which the diffusivity coefficient is time periodic.

The models of nonlinear competing processes on the base of the modification of the Lotka – Volterra system: the Richardson arms race model, the Lanchester war or battle model, the predator-prey model are presented and studied in the article. The qualitati... see more

This work deals with the model focuses on the study of the early stage of the immune cancer competition. The approach used in this model is based on the kinetic theory of active particles (KTAP), which has been developed to modeling systems constituted by... see more

ENGLISH ABSTRACT: Technology can be identified as the result of an innovation process that may be time-dependent. Furthermore, technology is both an input to the innovation process and an output of it. When two competing technologies ... see more

In this work, a principle for getting heteroclinic orbit of a dynamical system has been proposed when the solution is known in a compact form. The proposed principle has been tested through its application to a three species Lotka-Volterra system, which m... see more

In this study, we present a Lotka-Volterra predator-prey like model for the interaction dynamics of tumor-immune system. The model consists of system of differential equations with piecewise constant arguments and based on the model of tumor growth constr... see more
