Parallel implementation of optical symbolic substitution logic using shadow-casting and polarization.
We propose a parallel implementation method for optical symbolic substitution logic. The method uses shadow-casting principles for the efficient implementation of fundamental operations required in symbolic substitution logic; namely, image replication, spatial shifting, and combination. The use of light polarization allows for the implementation in parallel of several substitution rules withou...

متن کاملThroughput enhancement for optical symbolic substitution computing systems.
It is shown that by taking advantage of the superposition property of optical signals, one can further improve the performance of optical symbolic substitution processors.
متن کاملCasting a long shadow in the classroom
"What does one do when the giants pass away?" remarked a very famous microbiologist to me, soon after the death of Carl Woese in late 2012. I teach microbiology and introductory cell and molecular biology at a small undergraduate institution; Woese's example and contributions have long been part of every class I teach, and with good reason. Thus, I didn't know quite what to say to my colleague ...
متن کاملThe Weather-Beaten Dorsal Hand Clinical Rating, Shadow Casting Optical Profilometry, and Skin Capacitance Mapping
Laypeople commonly perceive some skin xerosis and withering (roughness) changes during winter on some parts of the body, particularly on the dorsal hands. The aim of the study was to assess the withered skin surface changes occurring during the four seasons. A total of 47 menopausal women completed the study. A group of 31 volunteers were on hormone replacement therapy (HRT) and 16 were out of ...
