Sistema para la adaptación de servicios a nivel de presentación y de navegación en portales web

Este documento describe SADI, un sistema de adaptación al despliegue de información en sistemas basados en la Web, se analiza el proceso de caracterización y enriquecimiento de servicios de información base, agregando características de visualización y de interacción para generar interfaces dinámicas y adaptables con base en atributos del usuario, de la empresa proveedora del servicio y del dispositivo de consumo. Para el sistema propuesto, SADI se definen los modelos de caracterización de servicios, de componentes de interfaz, de identidad visual y de despliegue, además, se propone el proceso de adaptación y se desarrolla un prototipo de implementación.This paper describe sSADI, a display adaptation system oriented to web-based system which analyzes the process of characterization and enrichment based on information services, adding interactive and visualization features to generate dynamic and adaptive interfaces based on user attributes, the company that which provides the service and the consumer device. For the proposed system, SADI characterization defines service models, interface components, visual identity and display, and then, it proposes the adaptation process and develop a prototype implementation.Magíster en Ingeniería de Sistemas y ComputaciónMaestrí

Pervasive handheld computing systems

The technological role of handheld devices is fundamentally changing. Portable computers were traditionally application specific. They were designed and optimised to deliver a specific task. However, it is now commonly acknowledged that future handheld devices need to be multi-functional and need to be capable of executing a range of high-performance applications. This thesis has coined the term pervasive handheld computing systems to refer to this type of mobile device. Portable computers are faced with a number of constraints in trying to meet these objectives. They are physically constrained by their size, their computational power, their memory resources, their power usage, and their networking ability. These constraints challenge pervasive handheld computing systems in achieving their multi-functional and high-performance requirements. This thesis proposes a two-pronged methodology to enable pervasive handheld computing systems meet their future objectives. The methodology is a fusion of two independent and yet complementary concepts. The first step utilises reconfigurable technology to enhance the physical hardware resources within the environment of a handheld device. This approach recognises that reconfigurable computing has the potential to dynamically increase the system functionality and versatility of a handheld device without major loss in performance. The second step of the methodology incorporates agent-based middleware protocols to support handheld devices to effectively manage and utilise these reconfigurable hardware resources within their environment. The thesis asserts the combined characteristics of reconfigurable computing and agent technology can meet the objectives of pervasive handheld computing systems
