purpose : to compare results of different methods for true corneal power determination and intraocular lens (iol) power calculation formulas in 10 eyes of 7 patients with previous radial keratotomy (rk) with or without astigmatic keratotomy methods : in this case series study, we determined the corneal power of 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy wit...

Longshore transport experiments were conducted in a large-scale physical model to evaluate predictions of the CERC formula with measured longshore sediment transport rates. It was found that the CERC formula produced reasonable estimates if the coefficient K was calibrated and applied to waves with similar breaker type. The calibrated K values are much smaller than values that are commonly used...

In this paper we rederive an old upper bound on the number of halving edges present in the halving graph of an arbitrary set of n points in 2-dimensions which are placed in general position. We provide a different analysis of an identity discovered by Andrejak et al, to rederive this upper bound of O(n). In the original paper of Andrejak et al. the proof is based on a naive analysis whereas in ...

Partial model checking was proposed by Andersen in 1995 to verify a temporal logic formula compositionally on a composition of processes. It consists in incrementally incorporating into the formula the behavioural information taken from one process — an operation called quotienting — to obtain a new formula that can be verified on a smaller composition from which the incorporated process has be...

The surface area of electrodeposited thin films of Ni, Co, and NiCo was evaluated using electrochemical double-layer capacitance, electrochemical area measurements using the [Ru(NH[Formula: see text])[Formula: see text]][Formula: see text]/[Ru(NH[Formula: see text])[Formula: see text]][Formula: see text] redox couple, and topographic atomic force microscopy (AFM) imaging. These three methods we...

The industry standard for pricing an interest-rate caplet is Black’s formula. Another distinct price of the same caplet can be derived using a quantum field theory model of the forward interest rates. An empirical study is carried out to compare the two caplet pricing formulae. Historical volatility and correlation of forward interest rates are used to generate the field theory caplet price; an...
