Ítem Revisión de lineamientos para el desarrollo de contenido educativo para televisión digital interactiva(Universidad Icesi, 2012-01-01) Abadia Quintero, Iván AlbertoColombia is in a migration from analog television to digital television, a fact implies do a authors review, which demonstrate the processes of creating applications for this medium, which interaction plays a important role. This is why it is vital for future developers and builders for digital television applications, understanding the different types of content that can be performed, their characteristics and particularly, the aspects and the design guidelines to consider in the development of this applications, know what could be the role of digital TV in learning contexts and how this medium represents a new option for communication and learning processes. The article shows a compilation of different positions related to creating content for digital television: methodologies for this purpose, interaction and design guidelines, and proposals for the usability evaluation for educational and interactive content for digital television.Ítem Metodología para la determinación de la huella ecológica en el área de exhibiciones del zoológico de Cali(Universidad Icesi, 2012-01-01) Torres Quintero, Sory Carola; Restrepo Montes, Luis Ángel; Moreno Duque, Marcela; López Astudillo, AndrésThe design, development and calculation of the Ecological Footprint are a universally accepted concept to measure and dimension the impact of human activities on natural resources. This article is the result of the investigation conducted at the Zoo of Cali (Colombia), in which an instrument was designed, applied and validated to determine the ecological footprint of the exhibition areas the different species of animals between July and November 2009. This is the first experience in Colombia to measure the footprint in a Zoo, which regards this service as a unique and exceptional activity. The development of this trail involved the lifting of eco maps and operational processes of each exhibition, as well as evaluating the types of resources consumed and the amount of waste they generate, to proceed to the calculation of the overall impact. The article is accompanied by an Excel tool, available for download at the site of the magazineÍtem Análisis espectral de parámetros fisiológicos para detección de emociones(Universidad Icesi, 2012-01-01) Valderrama Cuadros, Camilo Ernesto; Ulloa Villegas, Gonzalo VicenteThis paper show a literature review in the field of emotions detection. Show the strength of aplications of Brain Computer Interfaces (BCI) and what the functionality of it is. Explain how work with neourosignal and how to extract information using Discrete Wavelet Transform to recognize some characteristics that are present in the signal. Also explain the methods which are used for classification the signals. The purpose of the review is established a basis for the development of a project which want define the behavior of brain signal's when a person sees a commercial advertisement.Ítem Automated image analysis method for p-vivax malaria parasite detection in thick film blood images(Universidad Icesi, 2012-01-01) Millán, Jorge; Alarcón Ramirez, Andrés; Yunda, LeonardoAn image analysis method for Malaria parasite detection in thick film blood images is described. The developed method uses a combination of AGNES [Absence of gradients and Nernstian equilibrium stripping] and Morphological Gradient techniques in the image segmentation stage. Wavelet-based feature extraction is followed by a neural network classification stage. Principal Component Analysis (PCA) is used to reduce the number of features and improve the performance of the neuronal network. The true positive rate for determining a specific parasite was of 77.19%, while a 76.45% was obtained in determining at least a parasite in a microscopy image.Ítem Vol. 10 No. 20, Enero/Marzo 2012 / SISTEMAS & TELEMATICA(Universidad Icesi, 2012-01-01) Universidad IcesiEsta edición incluye: Presentación; Método automatizado de análisis de imágenes para detección del parásito de la malaria p-vivax en imágenes de gota gruesa; Metodología para la determinación de la huella ecológica en el área de exhibiciones del Zoológico de Cali; Análisis espectral de parámetros fisiológicos para la detección de emociones; Revisión de lineamientos para el desarrollo de contenido educativo para televisión digital interactiva; y la reseña del libro: El camino de Steve Jobs (Jay Elliot).
