In this study, the performance of three different self organization feature map (SOFM) network models denoted as SOFM1, SOFM2, and SOFM3 having neighborhood shapes, namely, SquareKohonenful, LineKohonenful, and DiamondKohenenful, respectively, to predict the critical factor of safety (Fs) of a widely-used artificial slope subjected to earthquake forces was investigated and compared. For this pu...
METHODS: Ocular wavefront maps were obtained from 19 normal eyes using a ShackHartmann aberrometer. The tenth Zernike order fit was considered to be the real wavefront of the eyes. Different fittings from second to ninth Zernike orders were computed and compared with the tenth order. The ratio of the root mean square (RMS) error between the different fittings and the original wavefront was calc...
PURPOSE To improve the reliability of corneal topographic data through the development of a method to estimate the magnitude of misalignment between successive corneal videokeratography (VK) maps and eliminate the effect of misalignment on the repeatability of topography data. METHODS Anterior and posterior topography maps were recorded twice for 124 healthy eyes of 124 participants using a P...
Here we present a new approach to calculating the square root of a quadratic matrix. Actually, the purpose of this article is to show how the Cayley-Hamilton theorem may be used to determine an explicit formula for all the square roots of $2times 2$ matrices.
land use maps are the most essential information in the hand of natural resources managers.in the present research, to prepare dahat abbas land use map, landsat etm+ (1386) data was used. the image was geometrically corrected with root mean square error of less than 0.47. for classification, artificial neural network, support vector machine and maximum likelihood methods were used.finally, thel...
