Background: The research context is the synchronous teaching of a mathematics visualised through signs, as is the Colombian sign language, which is publicly accessible, especially for the schooled deaf. Objectives: To analyse the cognitive demand of four ... see more

We study the relative role of the complex pore space geometry and wettability of the solid matrix on the quantification of relative permeabilities of elementary cells of porous media. These constitute a key element upon which upscaling frameworks are typi... see more

This paper is an extension of the earlier work titled “Giving birth to vectorial coordinate geometry”, which appeared in volume 3 of MathLab journal in 2019. While the novel concept of vectorial coordinates has been applied in the said work for the deriva... see more

The separation of color points is one of the important issues in computational geometry, which is used in various parts of science; it can be used in facility locating, image processing and clustering. Among these, one of the most widely used computationa... see more

This paper presents a method of simulating sound propagation and reconstruction for the virtual reality applications. The algorithm being developed in this paper is based on a ray sound theory. If we are given 3 dimensional geometry input as well as sound... see more

With regard to increase in growth of population in metropolitan areas around the world, the development of urban infrastructures in a way that is responsive to the population has become a major concern. Today, many cities are willing to use rail transport... see more

In this paper we study the behaviour of the admissible parameters of a two-intersection set in the finite three-dimensional projective space of order q=ph a prime power. We show that all these parameters are congruent to the same integer modulo ... see more
