Clustering of Geo-tectonics using GNSS data
Prof. em. Dr.Shunji Murai and Hideo Suzuki
If comparisons are made between the newly defined dynamic geo-tectonic map and the existing geo-tectonic and fault maps, the new image map shows much better relations with the distribution of earthquakes. It means that the dynamic geo-tectonic map would be much more useful for the prediction of earthquakes, as more than 70% of larger inland earthquakes occurred near the boundaries of the different clusters...

Detection of pest infestation area by visible bands vegetation indices
SitiNurfarhanaMd Noor and Abdul Rashid Mohamed Shariff
Indices T2 and T4 were able to show the infestation area clearly by producing images that have more colour contrast. A comparison between T2 and T4 indices showed both indices to have stability. However, T4 is more reliable due to smaller value of standard deviation.This study investigates the ability of different vegetation indices in detection of pest infestation area from UAV-RGB images...
