Sonographic estimation of fetal weight in term pregnant women
Introduction: Deviation from normal fetal weight and growth contribute to morbidity and mortality in the perinatal period. Over 50 formulas for EFW (estimated fetal weight) have been published and yet the ideal formula has not been determined. The objective of this study was to evaluate the accuracy of sonographic estimation of fetal weight using Hadlock formula in comparison to birth weight....
متن کاملPitfalls in Parameter Estimation for Delay Diierential Equations Department of Mathematics Pitfalls in Parameter Estimation for Delay Diierential Equations
In honour of Bill Gear on the celebration of his sixtieth birthday. Abstract Given a set of data fU(i) u(i ; p ?)g corresponding to the delay diierential equation u 0 (t; p) = f(t; u(t; p); u((t; p); p); p) for t t 0 (p); u(t; p) = (t; p) for t t 0 (p); the basic problem addressed here is that of calculating the vector p ? 2 R n. (We also consider neutral diierential equations.) Most approaches...
متن کاملPitfalls in Parameter Estimation for Delay Differential Equations
Given a set of data {U(γi) ≈ u(γi; p )} corresponding to the delay differential equation u′(t; p) = f(t, u(t; p), u(α(t; p); p); p) for t ≥ t0(p), u(t; p) = Ψ(t; p) for t ≤ t0(p), the basic problem addressed here is that of calculating the vector p ∈ Rn. (We also consider neutral differential equations.) Most approaches to parameter estimation calculate p by minimizing a suitable objective func...
متن کاملEstimation of Fetal Weight
Both low birth weight and excessive fetal weight at delivery are associated with an increased risk of newborn complications during labor and the puerperium. The perinatal complications associated with low birth weight are attributable to preterm delivery, intrauterine growth restriction (IUGR), or both. For excessively large fetuses, the potential complications associated with delivery include ...
متن کاملEstimation of Fetal Weight by Clinical Methods and Ultrasonography and Comparing With Actual Birth Weight
Introduction: Assessment of fetal weight is a vital factor in antenatal care, not only in the management of labor and delivery but also in identifying fetal weight disorders. Objective: This study compares the accuracy of clinical methods and ultrasonography in Estimating Fetal Weight (EFW) with Actual Birth Weight (ABW) in term pregnant women. Materials and Methods: This diagnostic test eval...
