Many Robots Make Short Work
Abstract Indoor mobile robots are becoming reliable enough in navigation tasks to consider working with teams of robots. Using SRI International’s open-agent architecture (OAA) and SAPHIRA robot-control system, we configured…

The Saphira Architecture for Autonomous Mobile Robots
Mobile robots, if they are to perform useful tasks and become accepted in open environments, must be autonomous: capable of acquiring information and performing tasks without programmatic intervention.

Word Predictability After Hesitations: A Corpus-based Study
We ask whether lexical hesitations in spontaneous speech tend to precede words that are difficult to predict. We define predictability in terms of both transition probability and entropy, in the…

Handling Compound Nouns in a Swedish Speech-Understanding System
This paper describes and evaluates a simple and general solution to the handling of compound nouns in Swedish and other languages in which compounds can be formed by concatenation of…

Disfluencies in Switchboard
Disfluencies are prevalent in spontaneous speech, and are relevant to both human speech communication and speech processing by machine. This paper reports selected results on Switchboard and two comparison corpora…

Automatic Linguistic Segmentation of Conversational Speech
We present a simple automatic segmenter of transcripts based on N-gram language modeling. We also study the relevance of several word-level features for segmentation performance. Using only word-level information, we…

Modeling Pitch Range Variation Within and Across Speakers: Predicting F0 Targets when “Speaking Up”
We study F0 variation produced by "speaking up", as part of a larger study of pitch range variation within and across speakers. We provide a function to predict target F0…

Unusual ribulose-1,5-bisphosphate carboxylase/oxygenase genes from a marine manganese-oxidizing bacterium
Initial DNA hybridization screening showed that SI85-9A1 possesses a gene similar to cbbL, the gene coding for the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO; EC 4.1.1.39). However, no RubisCO enzyme activity was…

Using Crest Line to Guide Surface Reconstruction from Stereo
We propose an approach to interleave surface reconstruction from multiple images and feature extraction using object-centered representation optimized to conform to the surface shape.
