Ítem Análisis, modelamiento y simulación de redes enmalladas basadas en el estándar 802.16-2004.(Universidad Icesi, 2005-07-25) Bustamante Miller, Roberto; Hincapié Reyes, Roberto CarlosThe following article is a presentation of mesh networks based on IEEE Standard 802.16-2004. Though it provides a general description of this standard, it also includes specific characteristics of mesh networks. It also discusses technology issues associated with existing gaps found in the above mentioned standard which have not yet been resolved. It also describes typical problems of mesh networks which hinder implementation of these kinds of networks besed on this or any other standard. The last section of this paper presents information on the progress being made as the result of the joint effort of the universities involved in this project, including the conclusions that heve been drawn so far.Ítem Sistemas y Telemática - No. 6 - Julio/Diciembre 2005(Universidad Icesi, 2005-07-01) Universidad IcesiEsta edición incluye: Arquitecturas tecnológicas y modelos de negocio para un operador de Hotspots inalámbricos WI-FI.

Due to this, it is very important the implementation of new and better technologies in these institutions and thus be able to increase the educative level. This work is based on the knowledge management theories, widely used in organizational environments in order to implement a system that can develop new knowledge and abilities in the Colombian students.Ítem Estudio cualitativo de arquitecturas orientadas a computación móvil(Universidad Icesi, 2006-10-11) Aedo Cobo, José Edinson; Vallejo Velásquez, Mónica AydéThe increase of the wireless networks has created a significant growth in demand for portable devices with different types of services such as text processing, connectivity to different networks, remote data base access and multimedia processing. In order to respond to these requirements, a number of different hardware architectures have been proposed recently, designed principally to integrate useful characteristics such as high performance for multimedia functions, energy efficient handling, small size and a low complexity. This work presents a general analysis of several architectures designed principally for real time multimedia processing in mobile applications. This article describes the advantages of these architectures and raises comparison strategy among them.Ítem Entorno para la visualización y la práctica con sistemas humanos a través de la Web (WESST - HS)(Universidad Icesi, 2006-10-11) Guerra Chávez, Lady J.; Navarro Newball, Andrés Adolfo; Lenis Trujillo, Javier A.; Vélez Beltrán, Jorge AlbertoThis paper presents the development of a Web Environment for Surgical Skills Training on Human Systems (WESST - HS). WESST - HS was conceived in order to satisfy the need to have a generic specification of an organ which could be further used within a surgical simulation. The initial goal was reached and surpassed; at the end, it was found that in medicine is better to treat organs like systems and that WESST - HS could be used independently. The generic specification is included in a web enabled Java application that lets the user interact with system’s and part’s information like shape, size, weight and color. Also, it is possible to display, scale, rotate and translate a three dimensional (3D) representation of the human systems from a file. This article is a description of the elements analyzed and developed in all the stages of the project.Ítem Public-Resource Computing: Un nuevo paradigma para la computación y la ciencia(Universidad Icesi, 2006-10-11) Osorio Betancur, Juan DavidThis article explores the Public-Resource Computing concept, an idea that has been successfully developed in the scientific community a few years ago, which involves the use of spare computational resources available in the millions of PCs in the world connected to Internet. We discuss the SETI@home project, the most successful example of this concept, and we describe the BOINC (Berkeley Open Infrastructure for Network Computing) platform, a software system created to make it easy for scientist to create and operate public-resource computing projects.Ítem Arquitecturas tecnológicas y modelos de negocio para un operador de Hotspots inalámbricos WI-FI.(Universidad Icesi, 2006-10-11) Varela, Claudia P.; Escandón, Alfredo; Castillo, Hector F.; Murillo, Sandra L; Millán, Andrés Felipe; Zúñiga Cañón, Claudia LilianaThis paper presents technology architectures and business models in wireless hotspot Wi-Fi service providers market. Besides to describe a business and technology model for Broadband Wireless Network (RIBA) of EMCALI Local Service Provider, this could be implemented in the Wireless Hotspots Colombian Providers.
