Ítem Aplicación y ventajas del conector "y posiblemente" en busquedas bipolares sobre el modelo GEFREDAlvarez Mendoza, Yigliana; Jaramillo Cobos, Roxana Andrea; Castillo Hernández, Jairo ErnestoFuzzy databases have been implemented in corporate and organizational level as an efficient and effective tool to carry out searches with values that can be vague, unknown, incomplete or null. In the same way, developments about bipolarity have allowed user to raise more flexible queries in terms of their proximity to natural language. The aim of this paper is to implement the fuzzy operator “and possibly” proposed by the theory of bipolar queries, in the generalized model of fuzzy relational databases (GEFRED). With this aim in mind, in the first part it is addressed the theoretical aspects about bipolarity and the GEFRED model that allow to think about an integration between both theories. Then, through an application, it is proposed the needed procedures and the emerging advantages of use of fuzzy operator.Ítem Arquitectura para escaneo de puertos usando agentes móvilesRocha Hernández, July Andrea; Jaramillo Cobos, Roxana Andrea; Wanumen Silva, Luis Felipe; Wanumen Silva, Luis FelipeThis article a software architecture approach for scanning ports is done using mobile agents, aiming network traffic monitoring detecting vulnerabilities in operating systems’ logic ports. The exposed architecture allows local executions in every computing device; it aggregates communication mechanisms to the agents, routes planning, choosing best route for each assigned agent in a network host, given correct task assignment in best moment and scenario achieving best mobile agent system possible takin into account that the amount of architectural details depends on each system size. This solution gives high availability of distributed environment and diminished network traffic by using intelligent agents allowing a communication to other agents informing a probability of a security attack to a certain port. The architecture is validated through Scan Mobile UD prototype, being developed in Java language technology implementing Aglets, and tested in a developed network, proving agents’ mobile effectivity to detect logical network vulnerabilities risks in proposed architecture.
