PURPOSE To compare intraocular pressure (IOP) measurements of the Ocular Blood Flow (OBF) pneumotonometer, Goldmann applanation tonometer, and Tono-Pen in eyes with normal corneas of various thicknesses. METHODS IOP was measured with an OBF pneumotonometer, Tono-Pen and Goldmann applanation tonometer in random order in 181 eyes with normal corneas.… (More)
A highly accurate model predicts microcomputer price based on benchmark performance by analyzing the impact on predicted price of fluctuations in system configuration and benchmark results.
The nonlinear least squares problem is a special case of the unconstrained minimization problem. While a large number of new algorithms have been developed in recent years, both for general unconstrained minimization and the least squares case, comparative studies are limited. Further, there has been practically a revolution in algorithm testing and… (More)
