Grayscale images are fundamental to many image processing applications like data compression, feature extraction, printing and tone mapping. However, some information is lost when converting from color grayscale. In this paper, we propose a light-weight high-speed decolorization method based on human perception of temperatures. Chromatic aberration results differential refraction light dependin...

a succession of late campanian- early maastrichtian is analyzed from gurpi formation with regard to the calcareous nannofossils. correlation matrix was applied for the first time to the entire nannofossil assemblage to reconstruct environmental conditions. a detailed quantitative calcareous nannofossil analyses is performed on samples in order to further investigate the climate events, and inte...

As a means of extending the significance of findings in experimental psychology and nonvisual psychological lighting research to digital game research, the present study was designed to investigate the impact of warm (reddish) and cool (bluish) simulated illumination in digital game worlds on game users' affect and play performance. In line with some previous findings, we predicted that lightin...

Growth of largemouth bass, Micropterus salmoides, was tested under constant (1 5" C, 29" C) and cyclic ( I 8 h at 15" C, 6 h at 29" C) temperature conditions. Six groups of 10 fish each were tested; one group under each constant condition, and four groups in the thermocycles. The four latter groups differed in the timing of their feeding; one group each was fed at the start and middle of the wa...

BACKGROUND Seasonal variation of flow-mediated vasodilation (FMD) remains controversial. A large cohort study showing that FMD was highest in summer and lowest in winter has been performed in a cross-sectional manner on different populations in different seasons, and the results for the same population were not compared. METHODS FMD was compared between the cool season (14.4 ± 4.4°C) and warm...

The light-emitting-diode (LED) revolution has drastically decreased the quality of United States’ night sky. LEDs are brighter than sodium doublet lighting fixtures they replacing, causing an increase in light pollution. Emerging technology promises to replace high-color-temperature LED with lower-color-temperature that reduces High-color-temperature, or “cool-lighting” causes unnecessary amoun...

Piglets from birth to wean at 21 days of age were subjected to heat lamps with either constant power output (CO) of 175 W or variable power output (VO) from 175 W at birth to 100 W by weaning time. Each type of heat lamp had either clear or red radiant rays. The effects of lamp output and color on heat lamp usage (HLU) and average daily gain (ADG) of the piglets were examined for a cool air tem...
