The Time Adaptive Self Organizing Map for Distribution Estimation
The feature map represented by the set of weight vectors of the basic SOM (Self-Organizing Map) provides a good approximation to the input space from which the sample vectors come. But the timedecreasing learning rate and neighborhood function of the basic SOM algorithm reduce its capability to adapt weights for a varied environment. In dealing with non-stationary input distributions and changi...

Determination of radiological map of radionuclides distribution in soils around of Shazand oil power plant
In this study, 34 soil samples were collected from the east of the Shazand power plant to the Arak city, with a length of 25 km. The specific activities of radionuclides of 226Ra, 232Th, 40K, and 137Cs were determined using gamma-ray spectrometry method. Gamma-ray spectra registered to employ high purity germanium (HPGe) detector with 30% relative efficiency. Specific activities of correspondi...
