Ítem Software platform for services in Colombian cities using the Living Labs approach(Ieee, 2011-12-05) Navarro Cadavid, AndrésComponent Based Software Engineering is a way to improve software modularization and to embed architectural concerns in the source code. Making explicit the architectural concerns in code helps to mitigate the problem of architectural erosion. The restructuring of legacy code with components in mind requires the use of tools to assess compliance with component programming principles. The property of communication integrity is one of the major principles for implementing software architectures. However, there is a paucity of tools for assessing the quality of code components. To cope with this issue, we define a component model in Java and a tool for identifying component types, which relies on a set of rules to statically check potential violations of the communication integrity property in Java source code. We illustrate its application with a case study and report the results of our experiments with it.Ítem TEST: Serious games for radio communications learning(Ieee, 2013-12-19) Pradilla, Juan VicenteThe game industry has suffered an impressive explosion of popularity, becoming the largest entertainment industry in the world. Games have become a sophisticated extension of the reality and an interesting way for complementing human mind utopias. Training software allows the trainee to immerse in quasi-real controlled situations that could be measured by trainers. In this work we discuss the duality existing between the training based on a serious game and a simple game, based on state of the art technologies. Then we show a training system for telecommunications technicians based on a combination between serious games and "traditional" e-learning platform. We show results for a trial made with a group of students from different disciplines (not only engineering) in order to evaluate learning outcomes using serious games versus other learning approaches. In this paper we discuss such results and make a descriptive statistical analysis of the resultsÍtem Vertical handoff algorithms - A new approach for performance evaluation(IEEE, 2010-12-06) 2010 IEEE Globecom Workshops, GC'10A myriad of Vertical Handoff Algorithms (VHA) have been proposed by researchers and networks practitioners. These algorithms allow mobile terminals (MT) to maintain the network connection when they switch from one wireless network to another one. Given the amount of proposed VHA and the need for an objective assessment of these solutions different evaluation methodologies have been proposed, becoming the problem of evaluation of VHA in an interesting challenge. However, there is no consensus on how to evaluate performance of VHA. In this paper, we address this issue by proposing a new approach for evaluating the VHA, which is based on multi -criteria evaluation and criticality analysis - a specific concept taken from the operational reliability. The new approach allows evaluating VHA using measured values of some defined parameters, which can be obtained from simulating VHA on a network simulation tool (e.g. NCTUns, NS -2, OMNET++, among others) or generic software simulation tools (e.g. MATLAB). As a test of the new model, an evaluation of five VHA is presentedÍtem Introduccion. Descripción del proyecto y del problema a resolver(Universidad Autónoma de Occidente, 2008-01-01) Navarro Cadavid, AndrésEl desarrollo del presente proyecto implica una combinación de diferentes conocimientos tanto de software como de hardware, relacionados con la computación móvil, middleware, agentes móviles y mecanismos de autenticación, que le permitan a un dispositivo móvil interoperar y desplazarse libremente haciendo uso de diferentes redes inalámbricas parn mantener su conec tividad sin que sea indispensable la intervención del usuario. Se desarrolla un mecanismo que permita movilidad semitrans parente, es decir, que permita al dispositivo móvil realizar el proceso de re-selección vertical, aunque no necesariamente Jwnd off vertical.Ítem Aprovisionamiento ágil – Clasificación de malware – Optimización Giraph.(Universidad Icesi, 2020-10-01) Gómez Manzanares, Juan Felipe; Pachon De La Cruz, Álvaro; Landínez García, Sebastián Felipe; Navarro Cadavid, Andrés; Loaiza, César; Tamura Morimitsu, Gabriel; IcesiEsta edición de Bitácoras de la Maestría es una buena muestra de la diversidad de problemas que se pueden resolver con el aporte de la informática. En el primer capítulo se trata tangencialmente un tema sobre el que hay mucha discusión, la industria 4.0, la denominada cuarta revolución industrial, con énfasis en “adaptación”. El tema del segundo capítulo es la seguridad de los dispositivos móviles que funcionan con un sistema operativo Android. El tercer capítulo presenta una solución para un problema de optimización complejo, el Rooted Distance-Constrained Minimum Spanning Tree (RDCMST), muy útil en temas con el diseño de redes de telecomunicaciones.
