Ítem Adaptive learning objects in the context of eco-connectivist communities using learning analytics(Elsevier BV, 2019-11-01) Diego, Mosquera; Carlos, Guevara; Jose, Aguilar; Diego, Mosquera; Carlos, Guevara; Jose, Aguilar; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las ComunicacionesEco-connectivist communities are groups of individuals with similar characteristics, which emerge in a connectivist learning process within a knowledge ecology. ARMAGAeco-c is a reflexive and autonomic middleware for the management and optimization of eco-connectivist knowledge ecologies using description, prediction and prescription models. Adaptive Learning Objects are autonomic components that seek to personalize Learning Objects according to certain contextual information, such as learning styles of the learner's, technological restrictions, among other aspects. MALO is a system that allows the management of Adaptive Learning Objects. One of the main challenges of the connectivist learning process is the adaptation of the educational context to the student needs. One of them is the learning objects. For this reason, this work has two objectives, specifying a data analytics task to determine the learning style of a student in an eco-connectivist community and, adapting instances of Adaptive Learning Objects using the learning styles of the students in the communities. We use graph theory to identify the referential member of each eco-connectivist community, and a learning paradigm detection algorithm to identify the set of activities, strategies, and tools that Adaptive Learning Objects instances should have, according to the learning style of the referential member. To test our approach, a case study is presented, which demonstrates the validity of our approach.Ítem The Aesthetic Pleasure in Design Scale for Spanish Speaking Countries: A Method for the Cross-Cultural Implementation and Adaptation of Psychometric Scales(SPRINGER, 2019-01-01) Garrido-Possauner L.M.; Maya J.One of the main issues in the field of product aesthetics is the lack of consistency in the instruments and terms being used to assess it. Several scales have been used but with restricted validity and reliability; notwithstanding, the APID (Aesthetic Pleasure In Design) scale developed in English, as part of the UMA (Unified Model of Aesthetics) project, lacks these limitations. Our research, being in a Spanish speaking country, required the scale to be in Spanish to be comprised and applied to domestic respondents. The adaptation of psychometric instruments with conceptual and linguistic challenging constructs, often is difficult, as the items used to assess the construct do not always have a direct translation. Also, it is possible for the adapted version to require different items that were not considered in the original instrument in order to preserve the content’s equivalence according to the target culture. A qualitative-quantitative mixed approach is proposed in order to overcome these issues. The resulting instrument has been statistically tested, proving to be both valid and reliable for the measurement of aesthetic pleasure in design. The final scale consists of five items: bonito, hermoso, agradable, llamativo and me gusta. This paper aims to improve the understanding of how aesthetic pleasure is perceived and therefore expressed by the local respondents gaining insight into how this construct is mentally represented and categorized by the respondents. It also aims to illustrate how psychometric scales based on respondents’ vocabulary have a great potential as usability assessment instruments. © 2019, Springer Nature Switzerland AG.Ítem Construction of a repertoire of analog form-finding techniques as a basis for computational morphological exploration in design and architecture(SPRINGER, 2018-01-01) Patiño E.; Maya J.The article describes the process of constructing a repertoire of analog form-finding techniques, which can be used in evolutionary computation to (i) compare the techniques among them and select the most suitable for a project, (ii) to explore forms or shapes in an analog and/or manual way, (iii) as a basis for the development of algorithms in specialized software, (iv) or to understand the physical processes and mathematical procedures of the techniques. To our knowledge no one has built a repertoire of this nature, since all the techniques are in sources of diverse disciplines. Methodologically, the construction process was based on a systematic review of the literature, allowing us to identify 33 techniques where the principles of bio-inspiration and self-organization are evident, characteristics both of form-finding strategies. As a result, we present the repertoire structure, composed of five groups of techniques sharing similar physical processes: inflate, group, de-construct, stress, solidify and fold. Subsequently, the repertoire’s conceptual, mathematical, and graphical analysis categories are presented. Finally, conclusions of potential applications and research trends of the subject are presented. © Springer International Publishing AG, part of Springer Nature 2018.Publicación Metodología para el desarrollo de sistemas interactivos usables CIAF+HCI, a partir de la integración de CIAF y MPIU+a(Universidad EAFIT, 2012) Villegas Ramírez, María Lili; Giraldo, William J.; Trefftz, HelmuthEn este trabajo se realiza la integración de dos propuestas enmarcadas en el desarrollo de sistemas interactivos, la primera (CIAF: “Collaborative Interactive Application Framework”) enfocada en el desarrollo de la interfaz de usuario y la segunda (MPIu+a: “Modelo de Proceso de la Ingeniería de la Usabilidad y Accesibilidad”) en la evaluación de la usabilidad. Esto con el fin de tener un método disciplinado y coherente que a partir de métodos, técnicas, herramientas, modelos y bases de conocimiento permita el desarrollo de sistemas interactivos usables. Se presenta, por tanto, un marco formalizado de desarrollo metodológico, conceptual y tecnológico que integra el diseño, el prototipado y la evaluación de la interfaz de usuario en todas las disciplinas. CIAF propone una aproximación metodológica para el desarrollo de interfaces de usuario y está basada en el uso de varios modelos para representar aspectos colaborativos e interactivos. Por tal razón, se usan diferentes notaciones y técnicas. Se describe en particular la integración de tres notaciones: -1- CIAN- la cual involucra aspectos de colaboración e interacción humano-computador, -2- UML - la cual especifica la funcionalidad de sistemas informáticos, y -3- usiXML- la cual describe la interfaz de usuario para múltiples plataformas. Adicionalmente, se describe cómo el modelo metodológico se integra dentro del proceso de Ingeniería de Software por medio de OpenUP. El proceso de desarrollo de modelos y la integración de diagramas está soportado mediante herramientas de Eclipse. MPIu+a, es una propuesta para el desarrollo de sistemas interactivos que integra modelos y tareas específicos para soportar la evaluación de la usabilidad en el ciclo de vida de la Ingeniería de Software, considerándola como un atributo de calidad de los sistemas interactivos. MPIu+a incorpora el prototipado y la evaluación, como dos elementos transversales a las fases básicas de desarrollo de software (Análisis de Requisitos, Diseño, Implementación y Lanzamiento).Publicación Plan de negocios para la enseñanza de programación a niños por medio de plataformas digitales(Universidad EAFIT, 2024) Prada Vásquez, Ronny Javier; Salazar Gómez, Francisco Javier; Giraldo Hernández, Gina MaríaPublicación Possible quantum algorithms for the Bollobás-Riordan-Tutte polynomial of a ribbon graph(SPIE-INT SOC OPTICAL ENGINEERING, 2008-01-01) Velez, M.; Ospina, J.; Universidad EAFIT. Departamento de Ciencias; Lógica y ComputaciónThree possible quantum algorithms, for the computation of the Bollobás-Riordan-Tutte polynomial of a given ribbon graph, are presented and discussed. The first possible algorithm is based on the spanning quasi-trees expansion for generalized Tutte polynomials of generalized graphs and on a quantum version of the Binary Decision Diagram (BDD) for quasi-trees . The second possible algorithm is based on the relation between the Kauffman bracket and the Tutte polynomial; and with an application of the recently introduced Aharonov-Arad-Eban-Landau quantum algorithm. The third possible algorithm is based on the relation between the HOMFLY polynomial and the Tutte polynomial; and with an application of the Wocjan-Yard quantum algorithm. It is claimed that these possible algorithms may be more efficient that the best known classical algorithms. These three algorithms may have interesting applications in computer science at general or in computational biology and bio-informatics in particular. A line for future research based on the categorification project is mentioned.
