Neural network application to unit commitment by Gray code

IEEE/PES Transmission and Distribution Conference and Exhibition, 2003
This paper introduces a unit commitment method based on artificial neural network (ANN) in which Gray code is used for encoding. Comparison of Gray code with binary and decimal codes is discussed. The experimental results indicate that the proposed ANN algorithm can significantly reduce the execution time in unit commitment based on binary codes, the ...

GRAY MARKETS IN THE UNITED STATES

Journal of Consumer Marketing, 1988
This paper examines the gray market for consumer products, with a particular emphasis on the reasons for gray market growth, the distinct channels of distribution for gray market products, and the means by which the gray markets may be terminated. Secondary emphasis is provided on the factors that lead to gray market emergence and on the impact of ...

Graying: gerontobiology of the hair follicle pigmentary unit

Experimental Gerontology, 2001
The visual appearance of humans derives predominantly from their skin and hair color. The phylogenetically ancient biochemical [corrected] pathway underling this phenomenon is called melanogenesis and results in the production of melanin pigments in neural crest-derived melanocytes, followed by its transfer to epithelial cells.

Hepatozoon griseisciuri INFECTION IN GRAY SQUIRRELS OF THE SOUTHEASTERN UNITED STATES

Journal of Wildlife Diseases, 1976
Blood films and selected tissue sections from 270 gray squirrels (Sciurus carolinensis) from 18 sites in 11 southeastern states were examined for Hepatozoan griseisciuri. This parasite was found in 110 (41%) squirrels from 17 of the 18 sites. Data suggested transmission of the parasite apparently occurs throughout the year and increases from spring to ...

DISEASES DIAGNOSED IN GRAY FOXES (UROCYON CINEREOARGENTEUS) FROM THE SOUTHEASTERN UNITED STATES

Journal of Wildlife Diseases, 1992
Diagnostic findings were reviewed on 157 sick or dead gray foxes (Urocyon cinereoargenteus) from the southeastern United States examined during the period 1972 through 1989. Most foxes (n = 118) originated from Georgia; fewer animals were from Florida, Kentucky, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Virginia and West ...

Ultrasound B‐scanning with a gray scale video hard copy unit

Journal of Clinical Ultrasound, 1975
AbstractA gray scale hard copy unit has been adapted to an ultrasound B‐scanner equipped with a video gray scale system and a conventional hard copier and a Polaroid camera. Comparative recordings were made of all three methods. The new hard copy unit produced a better gray scale image than Polaroid film, with reduction of cost and elimination of the ...
