in this paper a new method is presented which minimizes the destructive effects of measurement noise belonging to delays between receiver sites in accuracy of locating targets. for this purpose the geolocation equations are re-written by considering measurement error, therefore a cost function is introduced subject to position of sites, time difference of arrival of signals and measurement nois...

Gastric tonometer PCO2 measurement may help identify gut ischemia in critically ill patients but is frequently associated with large measurement errors. We tested the hypothesis that small bowel tonometer PCO2 measurement yields more accurate information. In 10 anesthetized, mechanically ventilated pigs subject to progressive hemorrhage, we measured gut oxygen delivery and consumption. We also ...

MEASUREMENT OF THE PARITY VIOLATING ASYMMETRY IN ELASTIC ELECTRON SCATTERING OFF Pb SEPTEMBER 2014 JONATHAN WILLIAM WEXLER, JR., B.A., HAMILTON COLLEGE M.S., UNIVERSITY OF MASSACHUSETTS AMHERST PH.D., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by Krishna Kumar The Lead Radius Experiment (PREX) was carried out in order to provide a modelindependent measurement of the RMS radius √ 〈r2 n〉 of the...

Serum BTP measurement is sometimes believed to be an alternative marker of glomerular filtration rate (GFR) assessment. The aim of the present work was to investigate the correlation between creatinine, cystatin C, and BTP values in sera and to compare the diagnostic efficacy for serum BTP and cystatin C with the glomerular filtration rate estimate. 25 individuals were tested. GFR was estimated...

In recent years, some researches have been done on simultaneous monitoring of multivariate process mean vector and covariance matrix. However, the effect of measurement error, which exists in many practical applications, on the performance of these control charts is not well studied. In this paper, the effect of measurement error with linearly increasing variance on the performance of ELR contr...

This study provides an evaluation of the latest Particulate Matter-Portable Emissions Measurement Systems (PM-PEMS) under different environmental and in-use conditions. It characterizes four PM measurement systems based on different measurement principles. At least three different units were tested for each PM-PEMS to account for variability. These PM-PEMS were compared with a UC Riverside’s mo...

In a two-view setting, we are interested in finding the most likely camera poses T w 1 and T w 2 , both in the space SE(3) of 3D poses, and 3D points Pw j ∈R3, with j∈ 1..n, which we can do by minimizing the re-projection errors f (T w c ,P w; p) = ‖h(T w c ,Pw)− p‖Σ associated with each measurement p ∈ R2. Above, the measurement function h : SE(3)×R3→ R2 predicts the measurement p from the unk...

If r 1, and m and n are each a multiple of (r + 1)2 + r2, then each isomorphic component of Cm ×Cn admits of a vertex partition into (r + 1)2 + r2 perfect r-dominating sets. The result induces a dense packing of Cm × Cn by means of vertexdisjoint subgraphs, each isomorphic to a diagonal array. Areas of applications include efficient resource placement in a diagonal mesh and error-correcting cod...

INTRODUCTION: Gd-DTPA (MagnevistTM) is one of the most widely used MRI contrast agents (CAs) today. The relaxation enhancement of Gd-DTPA depends on its relaxivity which in turn depends on factors like magnetic field strength, macromolecular content, pH and temperature.[1, 2, 3, 4] Knowledge of relaxivity is essential in many MRI areas. The Gd-DTPA concentration ([Gd]) is calculated from signal...
