Simplification of a Three-Constant Intraocular Lens Calculation Formula to a Single-Constant Approach: The Haigis Formula [PDF]
DiagnosticsBackground/Objectives: To derive and validate a simplified modification of the Haigis intraocular lens (IOL) power calculation formula by reducing the three-constant effective lens position (ELP) model to a single constant while introducing an optimized ...

Unique-Solution Single-Sample Complex Dielectric Characterization Through Linear Phase Approximation
IEEE Open Journal of Antennas and Propagation, 2022 This paper presents a transmission-only (TO) approach that solves the long-standing problem of transmission phase ambiguity. The approach considers a linear frequency-dependent phase approximation to derive the phase mode value analytically and uniquely ...

Constant Leverage And Constant Cost Of Capital: A Common Knowledge Half-Truth
Estudios Gerenciales, 2008 A typical approach for valuing finite cash flows is to assume that leverage is constant (usually as target leverage) and the cost of equity, Ke and the Weighted Average Cost of Capital, WACC are also assumed to be constant.
