Youth in schools with GSAs reported less truancy, smoking, drinking, suicide attempts, and sex with...

This paper suggests the use of Gravitational Search Algorithms (GSAs) in fuzzy control systems tuning. New GSAs are first offered on the basis of the modification of the depreciation equation of the gravitational constant with the iteration index and of an additional constraint regarding system’s overshoot. The GSAs are next used in solving the optimization problems which minimize the discretet...

The Glaucoma Stereo Analysis Study (GSAS) is a multicenter collaborative study of the characteristics of glaucomatous optic disc morphology using a stereo fundus camera. Using GSAS dataset, the formulas for predicting different glaucomatous optic disc appearances were established. The GSAS dataset containing three-dimensionally-analyzed optic disc topographic parameters from 187 eyes with prima...
