Antipersonnel landmines in the Colombian internal conflict: implications for technology development
(National University of Colombia, 2020) Jesus Antonio Vega Uribe; Hichem Sahli; Alain Sellier
The effort of universities, companies, and the state in Colombia to face home-made AP landmines has generated useful solutions and studies for many projects developed in the last decade, including demining processes in Colombia. Antipersonnel mines have changed in the last 15 years, due to the intermittent nature of our internal conflict. For example, as Descontamina Colombia mentions on its website, non-state armed groups cut the detonator containing the primary explosive to decrease the metal in the mine. This paper shows the aspects of the conflict that have affected humanitarian demining in Colombia, which help in the design and construction of technological devices. This article does not attempt to describe each of the typical technologies in humanitarian demining processes, but rather to show the characteristics considered in the design of two detection devices aimed at detecting home-made AP landmines.
Clasificación y detección de fallas en Sistemas Dinámicos
(Universidad de Los Andes, 2006) Javier Hernando Pardo Mayorga; Alain Sellier
In the dynamic systems a fail can occur in any moment, the fail can be present for variations in one or more parameter of the dynamic system. This paper present a fail detection in a non linear system compose by two tanks in parallel one with constant transversal area and the other one with variable area, the work is develop with adaptive observers and LAMDA classification. The application on this paper is in a non linear system, the level control in the two tank system.
