We study the problem of estimating surface area boundary ∂S a sufficiently smooth set S⊂Rd when available information is only finite subset Xn⊂S. propose two estimators. The first makes use Devroye–Wise support estimator and based on Crofton’s formula, which, roughly speaking, states that (d−1)-dimensional enough mean number intersections randomly chosen lines. For purpose, we an such lines wit...

The purpose of this study was to determine the body surface area (BSA) based on the alginate method, to derive formulae for estimating BSA, and to compare the error of the present formula to previous formulas obtained from other countries. We directly measured the entire body surface area of 34 males (20-60 years old, 158.5-187.5 cm in height, 48.5-103.1 kg in body weight) and 31 females (20-63...

Echocardiographic data from 92 younger normal subjects (1 month to 23 years of age) and 136 older normal subjects (20-97 years of age) were pooled and analyzed to obtain prediction equations for normal echocardiographic values. Using a bivariate regression model with the assumption that variability is constant as a percentage of the expected value, we developed regression equation and graphs th...

The average dosage rate of digoxin given in a group of infants, when related to body surface area, was twice as high (and when related to body weight, five times as high) as that employed for the maintenance therapy of adult controls. The resulting ...

Demetrius A Miminas is a Postgraduate MSc Student at Cardiff University and a Trust-grade Plastic Surgeon at Russells Hall Hospital, Dudley Group of Hospitals NHS Trust, Dudley, West Midlands Measurement of wound size and, more specifi cally, surface area is an important aspect of assessing any wound. With regards to burn wounds this measurement, expressed as percentage of the total body surfac...

A method for the fast generation of solid molecular surfaces is described. Based on a three dimensional grid, a template driven procedure generates the so called “contact surface“, also known as Connolly surface. The main advantages of this method are its good perfarmance and that it directly generates continuously tessellated

In this chapter the theory of scattering of elastic surface waves is described. Since surface waves are guided along the surface of materials, the scattering properties of surface waves are useful for probing the heterogeneity of the material near the surface as well as perturbations of the free surface. This has applications in the detection of surface defects (Steg and Klemens, 1974) and in s...
