Abstract

Since ancient times, humanity has been curious about the possibility of other worlds similar to Earth in the vast universe. While this question has intrigued scientists and dreamers alike, in recent years we have gained valuable clues thanks to technological advances and space missions. One of the most exciting destinations in our search for Earth-like celestial bodies is Titan, Saturn's largest moon. Although Titan differs in several fundamental aspects from our planet, it possesses amazing features that have sparked the interest and imagination of scientists. With its dense atmosphere composed mainly of nitrogen and its presence of liquids in the form of lakes and seas, including hydrocarbons such as methane and ethane, Titan has become a key study object for understanding planetary processes and the possibility of life in extraterrestrial environments. different from those we know on Earth. In this introduction, we'll explore Titan's fascinating features and how they bring us closer to answering the fundamental question: Is there an Earth-like celestial body in the universe?, Research conducted by Collazos Sánchez J.

19. Adapting Codesign Techniques for the Construction of a Learning Environment of a Written Second Language for the D/deaf.

Abstract

In Brazil, many D/deaf persons use the country's official sign language, Libras, to communicate and develop a sociocultural identity. For most Libras users, learning how to read and write in Portuguese, the country's official written language, is a challenge. To address the problem, we present a framework for codesigning accessible technologies for and with D/deaf persons. In this paper, we describe and analyze the case study of an environment to support the teaching–learning process of written Portuguese as a second language. Our main contribution is the documented experiences of codesigning with D/deaf and hearing participants, through individual and collaborative work, which increased confidence and creativity and enhanced empathy through sharing own experiences. Various types of participants were included through the entire framework process, and important values were reinforced, such as ownership and self-determination. [ABSTRACT FROM AUTHOR]

43. SOCIAL METRICS APPLIED TO SMART TOURISM.

Abstract

We present a strategy to make productive use of semantically-related social data, from a user-centered semantic network, in order to help users (tourists and citizens in general) to discover cultural heritage, points of interest and available services in a smart city. This data can be used to personalize recommendations in a smart tourism application. Our approach is based on flow centrality metrics typically used in social network analysis: flow betweenness, flow closeness and eccentricity. These metrics are useful to discover relevant nodes within the network yielding nodes that can be interpreted as suggestions (venues or services) to users. We describe the semantic network built on graph model, as well as social metrics algorithms used to produce recommendations. We also present challenges and results from a prototypical implementation applied to the case study of the City of Puebla, Mexico. [ABSTRACT FROM AUTHOR]

Abstract

This paper proposes a set of evaluation criteria that can be applied to assess ergonomic, usability and collaboration aspects of multitouch surfaces and their applications. Multitouch surfaces are technologies that are becoming popular among users. Our proposal takes into account elements that are used for usability evaluation of interactive systems as well as features that have been suggested by researchers and developers for multi-touch surfaces and their applications. We illustrate how our proposed criteria can be applied by means of a case study, which has produced encouraging results., Las superficies multitáctiles son tecnologías que empiezan a tener un elevado uso. Se toman como referentes aspectos utilizados para la evaluación de usabilidad de sistemas interactivos, así como las características que los investigadores y desarrolladores sugieren que deberían tener las superficies multitáctiles y las aplicaciones desarrolladas. Se presenta una propuesta inicial de criterios que deberían tenerse en cuenta para incluir aspectos de ergonomía, usabilidad y colaboración en el momento de realizar evaluaciones para estas tecnologías. Se ilustra cómo se pueden aplicar los criterios propuestos a través de un caso de estudio que cuenta con resultados promisorios.

Abstract

En instituciones de educación superior (IES), es común que la evaluación de la investigación se realice con base en indicadores que de forma cuantitativa, estiman la calidad de productos científicos. Este documento describe un modelo de gestión de datos compartidos de publicaciones y proyectos, con diseño adaptable a otros productos, que permite la recolección de datos y su descripción con estándares de metadatos, con el propósito de agregar valor práctico a los datos de las IES y posibilitar la colaboración entre profesores al hacer público la producción de los usuarios. El modelo se ha implementado como una aplicación web diseñada desde la perspectiva de los sistemas de organización y sus diferentes niveles de conocimiento. Los usuarios de la aplicación web realizan tareas como inserciones, bajas, consultas, reportes y exportación de datos al formato Bibtex. Las consultas se llevan a cabo a nivel personal, general o bien, se puede acceder a la producción de cualquier otro usuario.
