This thesis envisions a public space populated with active visible surfaces which appear different to a camera than to the human eye. Thus, they can act as general digital interfaces that transmit machine-compatible data ...

This work presents a wearable heart monitor at the ear that uses the ballistocardiogram (BCG) and the electrocardiogram (ECG) to extract heart rate, stroke volume, and pre-ejection period (PEP) for the application of ...

The Web is a convenient platform to deliver information, but reading web pages is not as easy as it was in 1990s. This thesis focuses on investigating techniques to enhance web pages on desktop and mobile browsers for two ...

In the theoretical framework described in this thesis, attention is part of the inference process that solves the visual recognition problem of what is where. The theory proposes a computational role for attention and leads ...

This thesis presents a unified computational framework for the study of emotion that integrates several concepts and mechanisms which have been traditionally deemed to be integral components of intelligent behavior. We ...

Mobile devices nowadays contain state-of-the-art technologies and are considered "smart". However, we and others around us are often interrupted or embarrassed by these smart devices because the calls and messages received ...

The proliferation of inexpensive video recording hardware and enormous storage capacity has enabled the collection of retail customer behavior at an unprecedented scale. The vast majority of this data is used for theft ...

Double-gate MOSFETs represent a significant solution to transistor scaling problems and promise a dramatic improvement in both performance and power consumption. In this work, a planar lithographic process is presented ...
