Making tabletops useful with applications, frameworks and multi-tasking
The progressive appearance of affordable tabletop technology and devices urges humancomputer interaction researchers to provide the necessary methods to make this kind of devices the most useful to their users. Studies ...
Aspects of personal information valuation in web browsing and mobile communication
The goal of this dissertation is to provide insights into how web and mobile phone call users assign value to their personal information. Two user studies are presented. The first one used a refined Experience Sampling ...
Public visualization displays of citizen data: design, impact and implications
The constant development of ubiquitous computing has enabled the pervasive integration of sensing and display technologies in everyday public settings. Urban digital screens are increasingly dominating the visual cityscape, ...
Embodied decision making and its neural substrate
Decisions are the result of a deliberative process that evaluates the suitability of specific options. Studies about decision making have been mainly conducted by using restricted tasks in which humans or animals are ...
Analysis of ensemble expressive performance in string quartets: a statistical and machine learning approach
Computational approaches for modeling expressive music performance have produced systems that emulate human expression, but few steps have been taken in the domain of ensemble performance. Polyphonic expression and ...
Finding relevant people in online social networks
The objective of this thesis is to develop novel techniques to find relevant people in Online Social Networks (OSN). To that end, we consider different notions of relevance, taking the point of view of the OSN providers ...
Exploiting implicit user activity for media recommendation
This thesis explores in depth how to use the user browsing behavior, and in particular the referrer URL, in order to understand the interest of the users. The aim is, first, to understand the preferences of the users from ...
Characterizing and modeling web sessions with applications
This thesis focuses on the analysis and modeling of web sessions, groups of requests made by a single user for a single navigation purpose. Understanding how people browse through websites is important, helping us to ...
MAC design and analysis for MU-MIMO and full-duplex enabled wireless networks
IEEE 802.11 based wireless networks, especially the infrastructure based Wireless Local Area Networks (WLANs) or Wi-Fi networks, are hugely successful, and have become an indispensable part of our life at homes and working ...
Designing wearable and playful accessories to encourage free-play amongst school aged children : conception, participatory design and evaluation
De acuerdo a los estudios sociales, la vida cotidiana ha reducido las oportunidades de que los niños puedan disfrutar del juego libre, lo cual a largo plazo, puede perjudicar su desarrollo social y físico. La investigación ...
Deep stochastic sentence generation : resources and strategies
The present Ph.D. thesis addresses the problem of deep data-driven Natural Language Generation (NLG), and in particular the role of proper corpus annotation schemata for stochastic sentence realization. The lack of multilevel ...
A self-organizing management platform for wireless sensor networks
Through advances in sensor, networking, semiconductor and energy storage technologies, Wireless Sensor Networks (WSNs) are increasingly being deployed in many important applications to enable users to access information ...
DysWebxia : a text accessibility model for people with dyslexia
Worldwide, 10% of the population has dyslexia, a cognitive disability that reduces readability and comprehension of written information. The goal of this thesis is to make text more accessible for people with dyslexia by ...
Statistical analysis of neural correlates in decision-making
We investigated the neuronal processes which occur during a decision- making task based on a perceptual classi cation judgment. For this purpose we have analysed three di erent experimental paradigms (somatosensory, ...
Generating ideas for pictorial advertisements : starting with pictorial metaphors
Behind every good advertisement there is a creative concept, a Big Idea. In contrast to the countless number of ads, a small number of patterns of effective communication (idea templates) have been uncovered, which are ...
Fluctuations in perceptual decisions : cortical microcircuit dynamics mediating alternations in conscious visual perception
Fluctuations in perceptual decisions emerge when our brain confronts with ambiguous sensory stimuli. For instance, our perception alternates between two conflicting images when presented dichoptically to our eyes, allowing ...
Exploiting wireless local area network density to improve energy and bandwidth allocation in internet access networks
Residential access networks provide always-on connectivity at a constant maximum speed and constant energy consumption. However, their usage is not constant. Users combine disconnection periods with light usage periods and ...
Design and implementation techniques for location-based learning games
Over the past few years the use of computer-supported games for learning purposes has reported many educational benefits in terms of students’ motivation and engagement towards learning. However, the comprehensive integration ...
A statistical dynamic cardiac atlas for the virtual physiological human: construction and application
This thesis is centered on the construction of a cardiac atlas to serve as a common reference frame in the Virtual Physiological Human (VPH). The construction covers the entire construction pipeline, starting from a set ...
The cerebellum and anticipatory actions: computational modeling, robotics and neuroprosthetic studies
Animals excel in skilled motor behavior, especially when compared to arti cial systems. Several adaptive and predictive motor control frameworks have been proposed to account for such performance, but the underlying ...
