Age-structured mathematical modelling approach to short term diffussion of E-commerce in Spain

Lombana, Iván Camilo (2011-11-21)

A compartmental model based on a nonlinear differential equation system is developed to study the diffusion and future trends in short-term of E-commerce in Spain with available official data from INE. Stability and ...
Agent-Based Model to Study and Quantify the Evolution Dynamics of Android Malware Infection

Alegre Sanahuja, Juan; Camacho Vidal, Francisco Javier; Cortés López, Juan Carlos; Santonja, Francisco-José; Villanueva Micó, Rafael Jacinto (Hindawi Publishing Corporation, 2014-10-28)

[EN] In the last years the number of malware Apps that the users download to their devices has risen. In this paper, we propose an agentbased model to quantify the Android malware infection evolution, modeling the behavior ...
An introduction to random variables, random vectors and stochastic processes

Calatayud Gregori, Julia; Cortés López, Juan Carlos; Jornet Sanz, Marc; Villanueva Micó, Rafael Jacinto (Editorial Universitat Politècnica de València, 2019-10-01)
