Ítem Desarrollo de herramientas computacionales para la búsqueda de secuencias reguladoras de la transcripción en procariotas(Universidad Icesi, 2008-03-27) Pérez, Antonio; Pérez, Carlos Andrés; Falgueras, JuanThis paper deals with a PERL program for tracking the DNA sequences that join transcription factors regulating the genetic expression of prokaryotic cells. The gene sets where obtained from their expressions under the same environmental conditions. The model organism was the lactococcus lactis, an organism for which we possess its sequenced genome in gene bank format. The program found a larger number of possible regulatory sequences in the 5’ flanking region of the genes. The number of possible regulatory sequences was also determined for the amount of genes that made up the set. The program also located flanking gene sequences which could also be involved in its regulation but at a translational level. The comparison of the results with patterns obtained experimentally, was done by means of nucleotide position weight matrices, getting around 50% regulating sequences which coincide with those reported in the databases, indicating good program prediction capability, if you account for the fact that most prokaryotic cell regulating sequences have yet to be characterized by experimental methods.Ítem Implementación de una API para la interacción del guante P5 con entornos de realidad virtual desarrollados en Java y Java 3D(Universidad Icesi, 2008-03-27) Marín Tobón, César Augusto; Parra S., Ricardo Antonio; Herrera Botero, Francisco Julián; Navarro Newball, Andrés Adolfo; Escallón D., Antonio JoséThis paper presents a specifific API’s implementation process, this API allows the interaction of the P5 glove with virtual reality environments implemented in the programming language Java and its tool Java 3D. Also, an example program is implemented using the API. Then, a CPU and physical memory consumption tests is performed with the example. Finally, the conclusions obtained are specified.Ítem Lentes mágicas : Una herramienta de apoyo para la visualización en 3D(Universidad Icesi, 2008-03-27) Ortiz, Carlos Humberto; Popó, José Ricardo; Herrera Botero, Francisco Julián; Navarro Newball, Andrés AdolfoMagic lenses are tools which allow changing a work area according to specific selections and properties. This paper describes the work done aimed to extend the concept of magic lenses to allow seeing inside 3D models which are uploaded from an example application. In order to implement the lenses a ray tracing algorithm for image synthesis was used.Ítem Un modelo de referencia para la especificación y análisis de Sistemas de Información para Vigilancia en Salud Pública(Universidad Icesi, 2008-03-27) López Gutiérrez, Diego MauricioThe specification of Health Information Systems is one of the more difficult stages in a software development project, especially when the development team has a limited knowledge about health care domain, because of the complexity of health business processes. The paper presents a reference model for the specification and analysis of Information systems for Public Health Surveillance. The aim of this model is to facilitate the design of the Requirements and Analysis Models defined in traditional software development processes. The usability of the model was demonstrated by supporting the requirements specification and analysis of a public health surveillance system in the Department of Cauca, Colombia.The proposed approach enhances the reusability and interoperability of final systems and it can be extended to any information system in a different domain.Ítem Un sistema de vigilancia en salud pública para alertas tempranas(Universidad Icesi, 2008-03-27) López Gutiérrez, Diego MauricioThe paper describes a generic software architecture for Public Health Surveillance information Systems and the implementation of a reporting system for infectious diseases in rural areas, implementing such architecture. The architecture is a component-based, interoperable, flexible and open approach and the system is implemented using open source technologies. The software application has been piloted in the Department of Cauca in Colombia, in the framework of a telemedicine Project funded by the European Union Commission.Ítem Taxonomías de la visualización de información(Universidad Icesi, 2008-03-27) Guzmán Cortés, Oscar HernandoTaxonomies of information visualization are a very useful element to get a better understanding of its characteristics and approaches. This paper presents some of the main taxonomies related to information visualization. Some taxonomies are applied to specific application domains and another taxonomies are independents of its particular context of use. For both researches and users, knowledge of these taxonomies helps to choose the better development of information visualizations in their particular application areas.Ítem Vol. 5 No. 10 - Julio/Diciembre 2007 / SISTEMAS & TELEMATICA(Universidad Icesi, 2008-05-22T15:16:10Z) Universidad IcesiContenido: Desarrollo de herramientas computacionales para la búsqueda de secuencias reguladoras de la transcripción en procariotas; Un modelo de referencia para la especificación y análisis de Sistemas de Información para Vigilancia en Salud Pública; Implementación de una API para la interacción del guante P5 con entornos de realidad virtual desarrollados en Java y Java 3D; Un sistema de vigilancia en salud pública para alertas tempranas; Lentes mágicas: una herramienta de apoyo para la visualización en 3D; Taxonomías de la visualización de información
