The integrated exposure uptake biokinetic (IEUBK) model, recommended for use by the U.S. Environmental Protection Agency at residential Superfund sites to predict potential risks to children from lead exposure and to establish lead remediation levels, requires an interindividual geometric standard deviation (GSDi) as an essential input parameter. The GSDi quantifies the variability of blood lea...

This paper studies the problem of point cloud simplification by searching for a subset of the original input data set according to a specified data reduction ratio (desired number of points). The unique feature of the proposed approach is that it aims at minimizing the geometric deviation between the input and simplified data sets. The underlying simplification principle is based on clustering ...

paleolithic lithic assemblages are traditionally described on the bases of presence of a variety of tool types(typology) and of different knapping technologies. in this study we tried to investigate whether the presence ofdifferent groups of scrapers in the mar-tarik site assigned to the middle paleolithic represent specific function orjust different stages of the reduction process and constant...

Azimuth-only target location and tracking based on image vision is a passive method, which has become research hotspot of at present. Aiming the problem bearings only UAV, this paper establishes geometric model UAV bearings, finally realizes UAV. This first analyzes data flow chart. By defining position positioning with receiving signal established. GeoGebra used to visualize data. can determin...

Invariant foliations are geometric structures for describing and understanding the qualitative behaviors of nonlinear dynamical systems. For stochastic dynamical systems, however, these geometric structures themselves are complicated random sets. Thus it is desirable to have some techniques to approximate random invariant foliations. In this paper, invariant foliations are approximated for dyna...

Abstract. This article extends the Generalized Asypmtotic Equipartition Property of Networked Data Structures to cover the Wireless Sensor Network modelled as coloured geometric random graph (CGRG). The main techniques used to prove this result remains large deviation principles for properly defined empirical measures on coloured geometric random graphs. Application of the result to some case s...

The geometric homogeneity of rollers, namely the dimension and shape deviations among rollers in a roller bearing, is one most important manufacturing errors. However, to best authors’ knowledge, no specified investigation has been carried out on effects friction torque tapered bearings (TRBs). By introducing diameter deviation distribution form with deviation, this study presents mathematic mo...
