Determination Of Particle Size Distributions From Acoustic Wave Propagation Measurements, Ashok S. Sangani, Peter D. M. Spelt, Michael A. Norato, Lawrence L. Tavlarides Jan 1999

Determination Of Particle Size Distributions From Acoustic Wave Propagation Measurements, Ashok S. Sangani, Peter D. M. Spelt, Michael A. Norato, Lawrence L. Tavlarides

Ashok S. Sangani

The wave equations for the interior and exterior of the particles are ensemble averaged and combined with an analysis by Allegra and Hawley @J. Acoust. Soc. Am. 51, 1545 ~1972!# for the interaction of a single particle with the incident wave to determine the phase speed and attenuation of sound waves propagating through dilute slurries. The theory is shown to compare very well with the measured attenuation. The inverse problem, i.e., the problem of determining the particle size distribution given the attenuation as a function of frequency, is examined using regularization techniques that have been successful for bubbly liquids. It …

Field-Programmable Smart-Pixel Arrays: Design, Vlsi Implementation, And Applications, Sherif S. Sherif, Stefan K. Griebel, Albert Au, Dennis Hui, Ted H. Szymanski, Harvard Scott Hinton Jan 1999

Field-Programmable Smart-Pixel Arrays: Design, Vlsi Implementation, And Applications, Sherif S. Sherif, Stefan K. Griebel, Albert Au, Dennis Hui, Ted H. Szymanski, Harvard Scott Hinton

H. Scott Hinton

A smart-pixel array is a two-dimensional array of optoelectronic devices that combine optical inputs and outputs with electronic processing circuitry. A field-programmable smart-pixel array (FP-SPA) is a smart-pixel array capable of having its electronic functionality dynamically programmed in the field. Such devices could be used in a diverse range of applications, including optical switching, optical digital signal processing, and optical image processing. We describe the design, VLSI implementation, and applications of a first-generation FP-SPA implemented with the 0.8-μm complementary metal-oxide semiconductor–self-electro-optic effect device technology made available through the Lucent Technologies–Advanced Research Projects Agency Cooperative (Lucent/ARPA/COOP) program. We report spice simulations …

Graphic Novels And The Reluctant Reader, Gail De Vos Jan 1999

Graphic Novels And The Reluctant Reader, Gail De Vos

Gail de Vos

What has happened to influence this change? First, the quality of comic books, particularly graphic novels, is now formally acknowledged. Graphic novels, the sturdy, lengthy comic books that contain one story or a set of related stories, are now being sporadically reviewed in selection journals as well as being the focus of a large number of recent articles. But the most compelling reason is wider awareness of our highly visual culture and its impact on our youth. Far from receiving stories from television and film passively, readers of comic books are actively constructing meaning from the text and illustrations and …
