• #### A discrete-time queueing system with three different strategies ﻿

We consider a discrete-time Geo/G/1/inf system in which a customer that finishes its first essential service may opt to abandon the system, to receive a second optional service or to go at the head of the queue in order ...
• #### A Geo[X]/G[X]/1 retrial queueing system with removal work and total renewal discipline ﻿

In this paper we consider a discrete-time retrial queueing system with batch arrivals of geometric type and general batch services. The arriving group of customers can decide to go directly to the server expelling out of ...
• #### A Non Markovian Retrial Queueing System ﻿

Researches on retrial queues with non-geometrical retrial times is motivated by real computers and telecommunication networks, where retrial times can hardly be geometrical distributed. The inherent difficulty with ...
• #### A stepwise Cas course for solving First-Order Partial Diferential Equations ﻿

Partial Differential Equations (PDE) is a very important topic in advance Mathematics for Engineering. The three main first-order PDE problems that a basic course must deal with are: \begin{enumerate} \item {\bf Pfaff ...
• #### Advanced techniques to compute improper integrals using a CAS ﻿

Let us consider the following types of improper integrals: $$\int_0^\infty f(t)\:{\rm d}t \qquad ; \qquad \int_{-\infty}^0 f(t)\:{\rm d}t \qquad {\rm and} \qquad \int_{-\infty}^\infty f(t)\:{\rm d}t$$ \medskip Let ...
• #### An arriving decision problem in a discrete-time queueing system ﻿

This paper discusses a discrete-time queueing system in which an arriving customer may adopt four different strategies; two of them correspond to a LCFS discipline where displacements or expulsions occur, and in the other ...
• #### ¿Cómo podemos ayudar al alumnado de bachillerato con sus matemáticas en el inicio de sus estudios de ingeniería? ﻿

El objetivo principal de esta comunicación es describir la experiencia que, desde el año 2017, venimos desarrollando un grupo de Personal Docente e Investigador (PDI) de la Universidad de Málaga con el alumnado de nuevo ...
• #### Curso 0 Online de Aspectos Básicos de Matemáticas para alumnado de la Escuela de Ingenierías Industriales de la Universidad de Málaga ﻿

El objetivo principal de esta comunicación es describir la experiencia que, desde el curso 2018/2019, venimos desarrollando un grupo de 7 profesores de las Áreas de Matemática Aplicada y de Estadística e Investigación ...
• #### A Discrete-time Queueing System With Imperfect Information for the Server ﻿

We consider a discrete-time Geo=G=1=1 system in which a customer that finishes its fi rst essential service may opt to abandon the system, to receive a second optional service or to place at the head of the queue in order ...
• #### EDUMATICUS: EDUcación MATemática con TIC en Universidad y Secundaria ﻿

El objectivo principal de esta comunicación es presentar la actividad del grupo EDUMATICUS, EDUcación MATemática con TIC en Universidad y Secundaria, cuyo objetivo principal es elaborar materiales multimedia que sirvan ...
• #### Improving CAS Capabilities: New Rules for Computing Improper Integrals ﻿

There are diferent applications in Engineering that require to compute improper integrals of the first kind (integrals defined on an unbounded domain) such as: the work required to move an object from the surface of the ...
• #### Making more flexible ATISMART+ model for traffic simulations using a CAS ﻿

Traffic simulations usually require the search of a path to join two different points. Dijkstra’s algorithm [1] is one of the most commonly used for this task due to its easiness and quickness. In [2, 3] we developed an ...
• #### New functions for random samples generation using Stata 15 ﻿

In the 2017 Spanish Stata Users Group meeting, held in Madrid on October 19th, we introduced some functions for generating random samples from continuous and discrete distributions using STATA 13. In this talk, we will ...
• #### New rules for improving CAS capabilities when computing improper integrals. Applications in Math Education ﻿

In many Engineering applications the computation of improper integrals is a need. In [1] we pointed out the lack of some CAS when computing some types of improper integrals. Even more, the work developed showed that some ...
• #### A New Web-stepwise Solver for Ordinary Differential Equations ﻿

In this paper we introduce SODES (Step-wise Ordinary Differential Equations Solver) which is a new solver for Ordinary Dfferential Equations (ODE). SODES can be used not only as a solver but also as a tutorial for the ...
• #### Random samples generation with Stata from continuous and discrete distributions ﻿

Simulations are nowadays a very important way of analyzing new improvements in different areas before the physical implementation, which may require hard resources which could only be affronted in case of a high probability ...
• #### Server information mechanism in a discrete-time queueing system ﻿

This paper discusses a discrete-time queueing system in which an arriving customer may adopt four di erent strategies depending on the income information, two of them correspond to a LCFS discipline where displacements ...
• #### SFOPDES: A stepwise tutorial for teaching Partial Differential Equations using a CAS ﻿

Partial Differential Equations (PDE) are one of the most difficult topics that Engineering and Sciences students have to study in the different Math subjects in their degree. In this talk we introduce SFOPDES (Stepwise ...
• #### Simulating Realistic Traffic Flow in a Smart City ﻿

Dijkstra's algorithm is one of the most well known algorithm to solve the shortest path problem (SPP). When applied to real situations, although the shortest path can be computed with Dijkstra's algorithm, it is not always ...
• #### SMIS: A Stepwise Multiple Integration Solver Using a CAS. ﻿

Multiple Integration is a very important topic in different applications in Engineering and other Sciences. Using numerical software to get an approximation to the solution is a normal procedure. Another approach is working ...
