The authors evaluated the accuracy of topographic measurements with the laser tomographic scanner using a model eye. Diameter, depth, and shape at different axial lengths of four sample holes that simulated optic nerve heads in phakic and aphakic conditions were determined by confocal imaging. The computer-generated cross-section profiles of the simulated optic nerve heads corresponded well wit...

This paper considers an Type I Generalized Half Logistic Distribution. We discussed the scale (σ) and shape (θ) parameters estimation using the median ranks method (Benard‟s approximation). Rama Krishna(2008) 1 studied the Type I Generalized Half Logistic Distribution scale (σ) and shape (θ) parameters estimation using the Least Square Method in two step estimation method. Also we computed Aver...

In very large vocabulary hypothesis-verification systems, the fine acoustic matcher is usually the most time consuming, so that the main concern is reducing the preselection list length as much as possible. Traditionally, these systems use a too high fixed preselection list length, increasing computational demands over the really needed. The idea we are proposing is estimating a different prese...

This paper studies the performance of block coding on an additive white Gaussian noise channel under different power limitations at transmitter. New lower bounds are presented for minimum error probability codes satisfying maximal and average constraints. These tighter than previous results in finite blocklength regime, yield a better understanding structure good limitation. Evaluation these sh...

carbon nanostructures are famous structures which are used in several industries such as separation, treatment, energy storage (i.e. methane and hydrogen storage), etc. a successful modeling of activated carbon preparation is very important in saving time and money. there are some attempts to achieve the appropriate theoretical modeling of activated carbon preparation but most of them were almo...

the static pull-in instability of beam-type micro-electromechanical systems is theoretically investigated. two engineering cases including cantilever and double cantilever micro-beam are considered. considering the mid-plane stretching as the source of the nonlinearity in the beam behavior, a nonlinear size-dependent euler-bernoulli beam model is used based on a modified couple stress theory, c...
