Emergent behaviors and scalability for multi-agent reinforcement learning-based pedestrian models
2017
This paper analyzes the emergent behaviors of pedestrian groups that learn through the multiagent reinforcement learning model developed in our group. Five scenarios studied in the pedestrian model literature, and with different levels of complexity, were simulated in order to analyze the robustness and the scalability of the model. Firstly, a reduced group of agents must learn by interaction with the environment in each scenario. In this phase, each agent learns its own kinematic controller, that will drive it at a simulation time. Secondly, the number of simulated agents is increased, in each scenario where agents have previously learnt, to test the appearance of emergent macroscopic beha…
Islands of biogeodiversity in arid lands on a polygons map study: Detecting scale invariance patterns from natural resources maps.
2016
Many maps (geology, hydrology, soil, vegetation, etc.) are created to inventory natural resources. Each of these resources is mapped using a unique set of criteria, including scales and taxonomies. Past research indicates that comparing results of related maps (e.g., soil and geology maps) may aid in identifying mapping deficiencies. Therefore, this study was undertaken in Almeria Province, Spain to (i) compare the underlying map structures of soil and vegetation maps and (ii) investigate if a vegetation map can provide useful soil information that was not shown on a soil map. Soil and vegetation maps were imported into ArcGIS 10.1 for spatial analysis, and results then exported to Microsof…
Psychometric analysis of a perception scale on the usefulness of Moodle in the University
2014
Because of the relevance acquired by the learning management systems in higher education, and the spread of use of the Moodle platform in many academic institutions, a scale of perceived usefulness on the use of Moodle in this context is designed. Furthermore, the study tested the psychometric validity of the scale. The aim is to provide a reliable and valid instrument to measure the students’ perception about the usefulness of Moodle. From the population of university students in Educational Sciences field, the study obtained a sample of 754 subjects. The results show that the scale evaluates the utility of the platform adequately in five dimensions: content, activities, assessment, intera…
Business Model Canvas Should Pay More Attention to the Software Startup Team
2020
Business Model Canvas (BMC) is a tool widely used to describe startup business models. Despite the various business aspects described, BMC pays a little emphasis on team- related factors. The importance of team-related factors in software development has been acknowledged widely in literature. While not as extensively studied, the importance of teams in software startups is also known in both literature and among practitioners. In this paper, we propose potential changes to BMC to have the tool better reflect the importance of the team, especially in a software startup environment. Based on a literature review, we identify various components related to the team, which we then further suppor…
Un estudio de aplicación de las técnicas informáticas a la investigación histórica. El comercio mediterráneo franco-español a fines del siglo XVIII
1983
Durante el siglo XVIII buena parte de la vida económica, cultural y de las comunicaciones de los pueblos de la vertiente mediterránea, tienen en el mar su vehículo más importante. Las ciudades portuarias se convierten en los centros de tráfico de personas y mercancías; con ellas, las ideas y los nuevos conocimientos industriales. Todo da lugar a un tráfico efervescente que, por sí sólo, justifica el interés de su estudio. Aunque abundan los trabajos que abordan o uno solo de los tráficos o relaciones generales sin clasificar, los modernos métodos cibernéticos permiten establecer relaciones entre los diferentes datos disponibles que dan lugar, más fácilmente, a una visión más amplia y comple…

Efficient Transport Protocol for Networked Haptics Applications
2008
The performance of haptic application is highly sensitive to communication delays and losses of data. It implies several constraints in developing networked haptic applications. This paper describes a new internet protocol called Efficient Transport Protocol (ETP), which aims at developing distributed interactive applications. TCP and UDP are transport protocols commonly used in any kind of networked communication, but they are not focused on real time application. This new protocol is focused on reducing roundtrip time (RTT) and inter packet gap (IPG). ETP is, therefore, optimized for interactive applications which are based on processes that are continuously exchanging data.ETP protocol i…
Including functional usability features in a Model-Driven Development Method
2013
The Software Engineering (SE) community has historically focused on working with models to represent functionality and persistence, pushing interaction modelling into the background, which has been covered by the Human Computer Interaction (HCI) community. Recently, adequately modelling interaction, and specifically usability, is being considered as a key factor for success in user acceptance, making the integration of the SE and HCI communities more necessary. If we focus on the Model-Driven Development (MDD) paradigm, we notice that there is a lack of proposals to deal with usability features from the very first steps of software development process. In general, usability features are man…
E@: Art Education 3.0
2012
Utilizando un modo de expresión disruptivo y poco académico se pretende interesar a los profesores-artistas por el uso de las tecnologías de la información y comunicación para la Enseñanza Artística. Se presenta un espacio web, con formato de red social. Creada en 2009 por el grupo de investigación UAM-PR:007 “Recursos digitales para la Educación Artística”, pretende facilitar el desarrollo de actitudes abiertas y críticas ante la sociedad actual desdoblada entre el mundo real y el virtual, facilitar el aprendizaje continuo y a la actualización permanente que requiere el ejercicio de nuestra profesión.
E@: using internet as an artistic living space
2013
Abordando la red social denominada “E@” (www.arteweb.ning.com) como obra artística, nos preguntamos ¿Qué vemos? ¿Qué nos parece? ¿Qué es?. Los miembros de esta red trabajan en ella como artistas (creadores de imágenes) y también como docentes (arquitectos del conocimiento). Utilizan Internet para crear y exponer sus trabajos artísticos y docentes. Sus usuarios son invitados a implicarse en su propia formación como ciudadanos críticos y comprometidos, para el desarrollo de sus propias competencias culturales y artísticas. Se explicará dicha Red entendida como CASA, sin ubicación geográfica determinada, usada como espacio artístico habitable. Como casa-cimiento, respondiendo a unas caracterís…
