Terrain representation is a basic topic in the field of interactive graphics. The amount of data required for a good quality of the terrain offers an important challenge to developers of such systems. For users of these applications, the accuracy of geographical data is generally less important than its natural visual appearance. This makes it possible to(More)
Virtual and Augmented Reality have been widely used in many scientific fields for the last two decades in order to visualize complex data and information. Although both techniques are oriented to show users complex 3D environments by means of an intuitive and easy mechanism, they use to become useless to manipulate the information in an intuitive and(More)
The changes introduced into the European Higher Education Area (EHEA) by the Bologna Process, together with renewed pedagogical and methodological practices, have created a new teaching-learning paradigm: Student-Centred Learning.

California has a renewable portfolio standard (RPS) that requires its utilities to procure 33% renewable energy generation by 2020. The increase in variable generation from solar and wind, has led to discussions of future ramping needs to maintain grid reliability. The fluctuating generation supply due to renewables will require adequate flexible generators(More)
Multi-touch technology on tabletop displays lets children interact with digital objects in collaborative and competitive ways. Multi-touch tables are not a part of classroom instruction because of high cost and lack of meaningful applications. This thesis explores possible solutions to building hardware and software that support the engagement of children.(More)
— This paper presents a twofold view of campus-wide wireless networks: Users and network managers. Providing an easy network experience to the user while keeping the wireless network secure and manageable is a key issue. This paper presents the description of the vendor-independent approach to a secure wireless local area network being implemented on this(More)
In this paper, we present a study of the lexical richness of a corpus used for training statistical language models. We also present a comparative analysis of a given oral corpus – the DIME corpus – and a corpus obtained from the web – the WebDIME corpus. The results from this analysis are interesting because they identify several weaknesses of the WebDIME(More)
