Using movement and intentions to understand simple events
In order to understand ongoing activity, observers segment it into meaningful temporal parts. Segmentation can be based on bottom-up processing of distinctive sensory characterist...

Aging and the Use of Context in Ambiguity Resolution: Complex Changes From Simple Slowing
Older and younger adults' abilities to use context information rapidly during ambiguity resolution were investigated. In Experiments 1 and 2, younger and older adults heard a...

Performance Lower Bounds for Existing and New Uncoded Digital Watermarking Modulation Techniques
Abstract. Many coded digital watermarking systems development requires first the selection of a (uncoded) modulation technique to be part of a coded architecture. Therefore, perfo...

Delta-sigma modulator topologies with high immunity to pattern noise
This paper addresses the problem of pattern noise encountered in single-stage delta-sigma modulators in the presence of a DC input signal. By utilizing state-space matrices, we ex...
