We develop an abstract partial deduction method capable of solving planning problems in the Fluent Calculus. To this end, we extend \classical" partial deduction to accommodate both, equational theories and regular type information. We show that our new method is actually complete for conjunctive planning problems in the propositional Fluent Calculus. Furthermore, we believe that our approach c...

Recently, version 3.0a of the software package FEMLAB for solving multiphysics partial differential equations was released. In the present project we compared its performance with the previous release 2.3 and the package Fluent 6.1 in stationary laminar flow benchmark problems in two and three dimensions. It turns out that the new version is an essential improvement over the old version. It is ...

A study to further simulation research of a commercial chemical vapor deposition (CVD) reactor is presented. A simulation is created using the computational fluid dynamics software package, Fluent (version 4). The variation of gas temperature inside the reactor system, as a function of gas flow rate, is examined. Data is collected for trials of several initial flow rates and iterations. Results...

This study investigated the effect of lexical content on sentence production in nonfluent aphasia. Five participants with nonfluent aphasia, four with fluent aphasia, and eight controls were asked to describe pictured events in subject-verb-object sentences. Experiment 1 manipulated speed of lexical retrieval by varying the frequency of sentence nouns. Nonfluent participants' accuracy was consi...

BACKGROUND One contemporary view of stuttering posits that speech disfluencies arise from anomalous speech motor control. PURPOSE To verify the rest muscle tension and speech reaction time of fluent and stuttering adults. METHOD 22 adults, divided in two groups: G1--11 fluent individuals; G2--11 stutterers. Electromyography recordings (inferior orbicularis oris) were collected in two differ...

Neural control of rising and falling tones in Mandarin people who stutter (PWS) was examined by comparing with that which occurs in fluent speakers [Howell, Jiang, Peng, and Lu (2012). Neural control of fundamental frequency rise and fall in Mandarin tones. Brain and Language, 121(1), 35-46]. Nine PWS and nine controls were scanned. Functional connectivity analysis showed that the connections b...

Of 500 left brain-damaged patients with educational level above elementary school investigated with a standard quantitative battery for dissociation between oral and written expression, speech was found to be selectively impaired in seven (three with "pure anarthria," two with anarthria in the context of Broca's aphasia, and two with fluent aphasia with remarkable sparing of writing), and writi...

The Fluent Calculus has largely been focused on building agents that work individually. However, agents often need to interact with each other to learn more about their environment as well as to achieve their goals. One form of interaction is by means of communication. Effective, goal–oriented communication requires knowledge of other agents. This paper studies the problem of endowing agents wi...

The present study examined whether infant-directed (ID) speech facilitates intersensory matching of audio-visual fluent speech in 12-month-old infants. German-learning infants' audio-visual matching ability of German and French fluent speech was assessed by using a variant of the intermodal matching procedure, with auditory and visual speech information presented sequentially. In Experiment 1, ...

Williams Syndrome (WS) is a neurodevelopmental disorder of known genetic origin, characterized by serious delays in language onset yet relatively verbose, intelligible and fluent speech in late childhood and adulthood. How do motor abilities relate to language in this group? We investigated planning and co-ordination of the movement of the speech articulators (oromotor praxis) in 28 fluent-spea...
