INTRODUCTION Although dietitians play an important role in the anthropometric assessment, reports on measurements made by these health professionals rarely include estimates of measurement error. AIM To estimate of intraobserver precision for three common anthropometric measurements made by dietitians. METHODS Twenty six measurers performed measurements (upper mid-arm circumference, tricipi...

Professor Doob [5], in the charming introduction to his paper delivered at the last Berkeley Symposium, remarked that physicists write like physicists, while mathematicians write like mathematicians and only for posterity. I have been given to wonder at times, for whom it is that mathematical statisticians write, and specifically whether it is for statisticians. The mathematician, we know from ...

In this study, a simple and reliable square wave voltammetric (SWV) method was developed and validated for determination of diclofenac in pharmaceutical preparations and human serum. The proposed method was based on electrooxidation of diclofenac at platinum electrode in 0.1 M TBAClO4/acetonitrile solution. The well-defined two oxidation peaks were observed at 0.87 and 1.27 V, respectively. Cal...

Given floating-point arithmetic with t-digit base-β significands in which all arithmetic operations are performed as if calculated to infinite precision and rounded to a nearest representable value, we prove that the product of complex values z0 and z1 can be computed with maximum absolute error |z0| |z1| 12β √ 5. In particular, this provides relative error bounds of 2−24 √ 5 and 2−53 √ 5 for I...

Autism is a neurodevelopmental disorder characterized by problems with social-communication, restricted interests and repetitive behavior. A recent and thought-provoking article presented a normative explanation for the perceptual symptoms of autism in terms of a failure of Bayesian inference (Pellicano and Burr, 2012). In response, we suggested that when Bayesian inference is grounded in its n...

A micron-precision optical alignment system (OASys) for the PHENIX muon tracking chambers is developed. To ensure the required mass resolution of vector meson detection, the relative alignment between three tracking station chambers must be monitored with a precision of 25μm. The OASys is a straightness monitoring system comprised of a light source, lens and CCD camera, used for determining the...

This research has been conducted to establish a wheel-point device and evaluate its efficiency (precision, accuracy and time) with respect to the estimation of canopy percent in a pilot Artemisia stand in Khabr region of Baft, Kerman province, Iran in 2015. Several transects with different lengths (30, 60, 90, 120, 150 and 180 m) were established using the randomized sampling block with 5 repli...

This paper discusses the comparison between two kinds of features in clustering of some literary poems by the same author, the Romanian poet, Mihai Eminescu. Using Precision, Recall, Rand Index, Relative Precision and Purity measures we conclude that the topics of poems are better characterized by the phonemes as features than by geometric properties (described by six indicators: V/N ;A; Λ;V ar...

We propose a new approach of integrating a precision grammar into speech recognition. The approach is based on a novel robust parsing technique and discriminative reranking. By reranking 100-best output of the LIMSI German broadcast news transcription system we achieved a significant reduction of the word error rate by 9.6% relative. To our knowledge, this is the first significant improvement f...
