Learning tasks from demonstration is key to the flexibility of robots and their accessibility to non-programmers. We present a task learning framework that combines the strengths of discrete and continuous representations. The robot learns a set of criteria and expectations to represent the goal of a demonstrated task. The task consists of performing actions that fulfill expectations on objects...

Despite the fact that epistemic connectives are sometimes interpreted in concrete structures defined by means ofruns and clock time functions, one of the things which strikes one when studying multiagent logics is how abstracttheir semantics are. Contrasting this fact is the fact that real agents like robots in everyday life and virtual charactersin video games have strong links wit...

This paper uses a market potential approach to examine the evolution of the rail transport network of China and its spatial distributional impacts on local accessibility, with a particular focus on high-speed rail improvements. Accessibility is measured by using a “market potential” function that was derived from the general equilibrium model of the economic geography literature, and is empiric...

Bei der Implementation von Webauftritten gewinnt die Berücksichtigung der Barrierefreiheitsprinzipien aufgrund zunehmender mobiler Internetnutzung eine weiterhin steigende Bedeutung. Von unterschiedlichen internationalen Organisationen, wie z. B. der Web Accessibility Initiative, wurden Barrierefreiheitsrichtlinien entwickelt, darunter die WCAG 2.0, die als Grundlage für Entwickler, aber auch f...

A fundamental issue to improve the accessibility to information resources is how to efficiently deal with huge amount(s) of data. In this respect, ontology driven techniques are expected to improve the overlap between the Cognitive Space applied by the user and the Information Space, which is defined by the information providers. In this paper we describe a powerful method to extract semantic g...

Institutional Repositories (IRs) are predicated on contributions by members of a university community, particularly faculty members. In fact, faculty contribution is considered one of the success factors for an IR even though several studies have found a low rate of faculty submission. In order to learn how we might be able to address this problem, the present study investigated factors that mo...

We study the structure and evolution of the downtown Minneapolis, Minnesota skyway network. Developed by private building-owners, the network evolved from tree-like to grid-like over the course of 50 years. We find that decentralized forces with the goal of maximizing individual buildings’ profitability shaped the network. Our analysis shows that a building with greater office size, a sign of g...

This work presents the development of an HTML5 library that allows the building of LO's (Learning Objects) compatible with the SCORM (Shared Content Object Reference Model) standard and the way in which they have been implemented within the “Learning Management, Capture of Experience and Content Repository” (GACER, for its acronym in Spanish) learning platform from the National Institute of Ele...
