    Dynamic server allocation in virtual environments, using quadtrees for dynamic space partition
    (2003-01-01) Restrepo, A.; Montoya, A.; Trefftz, H.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    In actual applications of virtual environments, one of the problems that has received attention is the way to assign computational resources to those who participate in the system. In most cases, static resource allocation is used. Static allocation is simple but has several limitations, among them, the missutilization of resources. In this paper we present a proof-of-concept of a new system and report the results of experiments with a system that accomplishes dynamic resource allocation by using Quadtrees for space partitioning, in a Shared Virtual Environment.

    Improving the business processes management from the knowledge management
    (Association for Computing Machinery, 2016-01-01) Marta S. Tabares; Giraldo, Liliana; Aguilar, Luis; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    This paper proposes a model that integrates the knowledge management to the business processes management in order to improve the process performance. The proposal defines the knowledge management flow as an element that interacts with part workflows and provides rules and actions in the BPMN elements in order to improve the BPM. To achieve the aim, first, a survey was made in forty Colombian' companies in order to identify the state of the practice about business process management, knowledge management and their use through the workflows; then, different elements were identified and characterized in order to achieve the integration model proposed. This was experimented in forty business workflows of the companies analyzed. A use case shows how the interactions among model elements are, and how these can improve the process performance. This experience allowed to measuring the effect that the integration had in the business process management by means of a new metric that involve the knowledge management in the workflow. Finally, it was possible conclude that the knowledge management must be part to the BPM impacting directly the workflow, in order to improve the result offered to the organizational actors and customers.

    Simulating soft tissues using a GPU approach of the mass-spring model
    (2010-01-01) Leon, C.A.D.; Eliuk, S.; Gomez, H.T.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    The recent advances in the fields such as modeling bio-mechanics of living tissues, haptic technologies, computational capacity, and graphics realism have created conditions necessary in order to develop effective surgical training using virtual environments. However, virtual simulators need to meet two requirements, they need to be real-time and highly realistic. The most expensive computational task in a surgical simulator is that of the physical model. The physical model is the component responsible to simulate the deformation of the anatomical structures and the most important factor in order to obtain realism. In this paper we present a novel approach to virtual surgery. The novelty comes in two forms: specifically a highly realistic mass-spring model, and a GPU based technique, and analysis, that provides a nearly 80x speedup over serial execution and 20x speedup over CPU based parallel execution. ©2010 IEEE.

    TAG model: Referents to assess the level of ubiquity for a higher education institution
    (IEEE, 2012-01-01) Zea Restrepo, C.M.; Lalinde Pulido, J.G.; Agudelo, O.; Mejía, C.V.; Núñez, R.A.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
    TAG, in Spanish: Tecnología, Aprendizaje y Gestión (Technology, Learning and Management) is an ubiquitous learning model that aims becoming a point of reference for higher education institutions within their transformation processes in educational innovation. The model is built on three dimensions: Technology, Learning and Management, which are assessed through the identification of categories and properties, and their associated metrics and indicators to determine the levels of ubiquity in a higher education institution, enabling the organizacional diagnosis and the design of strategies to increment the ubiquity level. This paper introduces the conceptual guidelines that enables the definition of the main properties for each one of the TAG dimensions. © 2012 IEEE.
