How can we enable novice users to create effective task plans for collaborative robots? Must there be a tradeoff between generalizability and ease of use? To answer these questions, we conducted a user study with the CoSTAR system, which integrates perception and reasoning into a Behavior Treebased task plan editor. In our study, we ask novice users to perform simple pick-and-place assembly tas...

A major deficiency in state-of-the-art automatic speech recognition (ASR) systems is the lack of robustness in additive and convolutional noise. The model of auditory perception (PEMO), developed by Dau et al. (1996a) for psychoacoustical purposes, partly overcomes these difficulties when used as a front end for automatic speech recognition. To further improve the performance of this auditory-b...

In this section, we briefly present the formalism we use. This formalism aims at describing the state of a system and its dynamic behaviour in an algebraic framework [DG 94]. It was first introduced in a case study on a formal specification of the embedded safety part of an automatic subway pilot [DM 91], [Dau 92], [DGM 93], in order to cope with the large number of variables whose values made ...

HYPOTHESIS Performance in tone perception and production are correlated in prelingually deafened pediatric cochlear implant (CI) users across individuals. Demographic variables, such as age at implantation, contribute to the performance variability. BACKGROUND Poor representation of pitch information in CI devices hinders pitch perception and affects perception of lexical tones in cochlear im...

Background; Methadone maintenance therapy (MMT) is an evidence-based approach for opiate addiction treatment. While its effectiveness in reducing opiate use has been evidently verified, unanswered questions with respect to the cultural scenarios for MMT programs remain unanswered. This study was conducted to explore understanding address MMT initiation among a women-recruited sample of persons ...

OBJECTIVE The purpose of the present study was to test the hypothesis that cochlear implant (CI) users' music perception is correlated with their lexical tone perception, and the two types of perception share similar mechanisms in electric hearing. DESIGN A lexical tone perception test and a pitch interval discrimination test were administered to a group of CI users and a group of normal-hear...

Perception of safety and comfort of bicycle infrastructure is an important factor influencing the use of bicycles. Cyclists can be found all over India. In urban areas presently, mostly captive riders choose to bicycle as no other viable options of travel are available to them. This study discusses perceptions of these captive riders as compared to a group of not yet riding (potential) cyclists...
