This research was performed with the objective of evaluating the accuracy of spectral angle mapper (SAM) classification using different reference spectra. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) digital images were applied in the SAM classification in order to map the distribution of hydrothermally altered rocks in the Kerman Cenozoic magmatic arc (KCMA), Iran...

We have studied 1/f spectra in the human EEG(electroencephalogram), which are considered to be the characteristics of the self-organizing phenomena. In this paper we obtain 1/f spectra for neural network models: simplified models of the brain. In practice, we employ the coarse-graining method to a neural network model and obtain a 1/f spectrum. Furthermore we carry out computer simulations with...

We prove that under suitable circumstances, the spectra of a Schrödinger operator on the three intervals [0,1], [0, a], and [a, 1] for some a ∈ (0, 1) uniquely determine the potential q on [0,1].

The validity of three-component fitting of protein circular dichroism (CD) spectra in the peptide absorption region with basis spectra for helical, /?-sheet and unordered structure is examined by matrix rank analysis of protein CD spectra. It is shown that a three-component basis can be justified for several proteins within the limits of experimental error of the spectra. It is suggested that t...
