Estudio de la Experiencia de Usuario mediante un Sistema de Dashboards de Análisis de Aprendizaje Multimodal [PDF]
arXiv, 2023 In the article, we present a Web-based System called M2LADS, which supports the integration and visualization of multimodal data recorded in user experiences (UX) in a Learning Analytics (LA) system in the form of Web-based Dashboards. Based on the edBB platform, the multimodal data gathered contains biometric and behavioral signals including ...

A [in]Segurança dos Sistemas Governamentais Brasileiros: Um Estudo de Caso em Sistemas Web e Redes Abertas [PDF]
arXiv, 2021 Whereas the world relies on computer systems for providing public services, there is a lack of academic work that systematically assess the security of government systems. To partially fill this gap, we conducted a security evaluation of publicly available systems from public institutions.

Estudio Teórico del espectro de emisión para un sistema microcavidad-punto cuántico en una aproximación de campo medio (Theoretical study of emission spectrum for a quantum dot-microcavity system in a mean field approximation) [PDF]
, 2015 En este trabajo, se obtiene una expresi\'on num\'erica para calcular el espectro de emisi\'on de un sistema microcavidad-punto cu\'antico usando una teor\'ia de campo medio en el formalismo de la matriz densidad. El sistema modelado es un micropilar semiconductor que contiene un \'unico punto cu\'antico en el interior de la microcavidad, este sistema ...

Extractive Summarization: Limits, Compression, Generalized Model and Heuristics [PDF]
Computaci\'on y Sistemas 21(4) (2017), 2017 Due to its promise to alleviate information overload, text summarization has attracted the attention of many researchers. However, it has remained a serious challenge. Here, we first prove empirical limits on the recall (and F1-scores) of extractive summarizers on the DUC datasets under ROUGE evaluation for both the single-document and multi-document ...

Transição de fase no sistema de Hénon-Heiles (Phase transition in the Henon-Heiles system) [PDF]
Revista Brasileira de Ensino de F\'isica, 36, 2014, 4, 4313, 2017 The Henon-Heiles system was originally proposed to describe the dynamical behavior of galaxies, but this system has been widely applied in dynamical systems by exhibit great details in phase space. This work presents the formalism to describe Henon-Heiles system and a qualitative approach of dynamics behavior.

Semi-automatic vectorization of linear networks on rasterized cartographic maps [PDF]
Revista de Teledeteccion, 10 (1998), 2005 A system for semi-automatic vectorization of linear networks (roads, rivers, etc.) on rasterized cartographic maps is presented. In this system, human intervention is limited to a graphic, interactive selection of the color attributes of the information to be obtained. Using this data, the system performs a preliminary extraction of the linear network,
