This study investigated a method for conducting experimental analyses of academic responding. In the experimental analyses, academic responding (math computation), rather than problem behavior, was reinforced across conditions. Two separate experimental analyses (one with fluent math computation problems and one with non-fluent math computation problems) were conducted with three elementary sch...

Ten fluent speakers and nine developmental stutterers read isolated nouns aloud in a delayed reading paradigm. Cortical activation sequences were mapped with a whole-head magnetoencephalography system. The stutterers were mostly fluent in this task. Although the overt performance was essentially identical in the two groups, the cortical activation patterns showed clear differences, both in the ...

The paper reports on first preliminary results and insights gained in a project aiming at implementing the fluent calculus using methods and techniques based on binary decision diagrams. After reporting on an initial experiment showing promising results we discuss our findings concerning various techniques and heuristics used to speed up the reasoning process.

A leading computational fluid dynamics (CFD) software FLUENT is ported to the NCSA IA-32 Linux cluster with Myrinet interconnect. Scripts are written to integrate FLUENT with the open-source PBS scheduling system. Scalable performance of FLUENT is benchmarked with two engineering problems from Caterpillar Inc. and Fluent, Inc. A maximum of 64 processors are used to accommodate up to 10 million ...

We studied noun and verb naming in three main variants of frontotemporal dementia: the frontal variant(Fv-FTD), primary progressive aphasia (PPA) and semantic dementia (SD). We further distinguished PPA in nonfluent and fluent forms and restricted diagnosis of SD to subjects with progressive semantic breakdown leading to agnosia for words and objects. Fv-FTD and nonfluent-PPA named objects bett...

Most naming treatments in aphasia either assume a phonological or semantic emphasis or a combination thereof. However, it is unclear whether semantic or phonological treatments recruit the same or different cortical areas in chronic aphasia. Employing three persons with aphasia, two of whom were non-fluent, the present study compared changes in neural recruitment associated with phonologic and ...

It is often assumed that a main function of gestures is to compensate for expressive difficulties. This predicts that gestures should mainly occur with disfluent speech. However, surprisingly little is known about the relationship between gestures and fluent vs. disfluent speech. This study investigates the putative compensatory role of gesture by examining competent speakers’ and language lear...

Fluent Parallel Performance on Multi-Core System Wang Junhong Objective This benchmark work studies the performance of the parallel Fluent solver on the new multiple core system. Fluent solver was parallelised using the MPI method for communication and message exchange among processor units. Result and Findings The benchmark testings were conducted on one thread, and two, four and up to eight t...
