Near infrared reflectance spectroscopy (NIRS) provides an opportunity to measure cowspecific organic matter digestibility (OMD) from fecal samples. In this study individual digestibility measurements from a trial with 47 cows were investigated. Digestibility increased when lactation progressed. The repeatability estimates between different lactation stages were low which suggests that several f...
We present and evaluate an automatic method to define anatomical coordinate systems (ACSs) for 3D bone models of isolated arthritic knee. The method has acceptable repeatability and can also be used for the bone shape alignment. Keywords— 3D bone model, automation, shape alignment, medical imaging, shape analysis.
Analysis of heart rate variability (HRV) has become a popular non-invasive tool for assessing the activities of autonomic nervous system. Most of the methods were hired from techniques used for time series analysis. Currently used methods are time domain, frequency domain, geometrical and fractal methods. A new technique, which searches for pattern repeatability in a time series, is proposed fo...
the milk and milk fat production records of 28 holstein herds in khorasan razavi province were analyzed in this study. the records were based on 305 days of milking and were from the first to third milking periods and two times milking per day. the fixed effects of herd-year-season and age of dam at parturition as covariate were fitted in the models of analyses. the (co)variance components were...
A theoretical study was performed to determine the accuracy and repeatability of multiple one-dimensional pulse sequences in the quantification of glutamine concentration at 3 T. Variable repeatability (12% to > 50%) and significant absolute error (-50% to +70%) were noted for the eight pulse sequences considered. Data acquired in vivo using three of the pulse sequences used for simulation matc...
A major difficulty in evaluating in-vivo knee joint kinematics during walking is the artifacts created by movement of the skin and soft tissue relative to the underlying bones. An attachment system called exoskeleton has been proposed to remedy this problem; its precision is known as well as the repeatability of its calibration method. The objective of this study was to verify the intraand inte...
OBJECTIVE To assess the repeatability of measuring the pulsatility index of the uterine arteries using transvaginal color Doppler at 23 weeks of gestation. PATIENTS AND METHODS The pulsatility index was measured in 100 women with singleton pregnancies attending for routine transvaginal Doppler examination of the uterine arteries at 23 weeks. To assess the repeatability of different components...
BACKGROUND We studied the repeatability of the ambulatory arterial stiffness index (AASI), which can be computed from 24-h blood pressure (BP) recordings as unity minus the regression slope of diastolic on systolic BP. METHODS One hundred and fifty-two hypertensive outpatients recruited in Nijmegen (mean age = 46.2 years; 76.3% with systolic and diastolic hypertension) and 145 patients enroll...
This report presents the results of the repeatability evaluation for a friendly competition for formal verification of continuous and hybrid systems. The friendly competition took place as part of the workshop Applied Verification for Continuous and Hybrid Systems (ARCH) in 2017. In its first edition, thirteen tools have been applied to solve benchmark problems for the six competition categorie...
UNLABELLED The repeatability of rest and hyperemic myocardial blood flow (MBF) measurements using 82Rb PET has not been evaluated. The aim of this study was to investigate the short-term repeatability of such measurements. METHODS Fifteen healthy volunteers underwent rest and pharmacologic stress 82Rb PET, repeated 60 min apart. RESULTS There was no significant difference in repeated rest M...
