Precipitation Variability Assessment using GIS and Geostatistical Techniques: A Study of Chamarajanagara District, Karnataka, India
Abstract: AbstractPrecipitation is an important parameter for the life cycle of living beings; also it plays a major role in global and country economic system. If there is a decline in precipitation then whole agricultural and food chain imbalance will become more. The present study is conducted to assess the spatial and temporal changes in precipitation pattern. The precipitation is interpolated using ordinary kriging to represent spatial distribution. The coefficient of …

Automatic Detection of Air Holes Inside The Esophagus in CT Images
Abstract: Automatic esophagus segmentation is a challenging problem. The wall of the esophagus consists of muscle tissue, which has a low contrast to vessels, other muscles and lymph nodes. Shape and appearance can vary a lot. It appears solid if it is empty, but it can also be filled with air, remains of orally given contrast agent, or both. Even for a human, it is often impossible to accurately delineate the …
