on the meteorological site at the Experiment station, evapoEvaporation from fibreglass pans painted silver was less than ration from the metal pan was greater. from Class 'A' (metal) pans. Painting the fibreglass pans with dark paint decreased the difference in evaporation but the seasonal differences were not uniform. It was also shown that placing a screen over both types of pans decreased ev...

In this paper, highly efficient and simple monochrome blue, green, orange, and red organic light emitting diodes (OLEDs) based on ultrathin nondoped emissive layers (EMLs) have been reported. The ultrathin nondoped EML was constructed by introducing a 0.1 nm thin layer of pure phosphorescent dyes between a hole transporting layer and an electron transporting layer. The maximum external quantum ...

Image segmentation is very essential and critical to image processing and pattern recognition. This survey provides a summary of color image segmentation techniques available now. Basically, color segmentation approaches are based on monochrome segmentation approaches operating in di!erent color spaces. Therefore, we "rst discuss the major segmentation approaches for segmenting monochrome image...

A new approach to generate a pattern for any object of binary image is proposed. One of important compression techniques of any monochrome images without losing the information is chain code encoding principle. It is segmenting the connected component of each region at point of boundary. The boundary is located by selecting the point with coordinates and then transmitted. This continues to reac...

Images of outdoor scenes captured in bad weather suffer from poor contrast. Under bad weather conditions, the light reaching a camera is severely scattered by the atmosphere. The resulting decay in contrast varies across the scene and is exponential in the depths of scene points. Therefore, traditional space invariant image processing techniques are not sufficient to remove weather effects from...
