This paper presents an approach to compensate for the effect of thermal expansion on structure industrial robot and thus reduce repeatability difference in cold warm conditions. In contrast previous research this area that deals with absolute accuracy, article is focused determining achievable repeatability. To unify increase repeatability, measurements highly accurate sensors were performed un...

The objective of this project was to develop and test a software system for the kinematic analysis of total joint arthroplasty (TJA) implants. Using a supervised iterative optimization algorithm (simulated annealing), the system iteratively adjusts the pose of an implant model to maximize correlation between the model's pose and the pose of an actual implant in a x-ray image. A graphical user i...

An experimental study has been conducted on the hydrodynamics of a stage mixer-settler to obtain an appropriate design. In this paper several tests was performed to investigate full factorial design of experiments. Since each test was repeated seven times, the repeatability of the test was confirmed (P=1 bar and T=25 °C). Sauter diameter was determined by photographing both the mix...

Background Recent developments in cardiovascular magnetic resonance (CMR) perfusion have made it possible to rapidly acquire multiple slices continuously without the need for any ECG-triggering. Promising results have been shown for visual assessment and quantification of perfusion using self-gated techniques [1-3]. This work compares the repeatability of a free breathing ungated acquisition us...

We have been made aware that the estimate of individual repeatability that we used in our study (i.e. the intraclass correlation coefficient) overestimates repeatability, and that calculating repeatability using the analysis of variance-based method, as described by Lessells & Boag [1]), is a more appropriate estimate. Consequently, we have recalculated repeatability using this more appropriate...

PURPOSE To assess the three-dimensional repeatability of thickness measurements for epithelium, stroma, cornea, flap, and residual stromal bed using the Artemis very high-frequency (VHF) digital ultrasound arc-scanner (ArcScan Inc). METHODS Five consecutive measurements were obtained for 10 eyes of 10 patients 1 year after LASIK using the Artemis VHF digital ultrasound arc-scanner across the ...

the present research was designed to examine the genetic analysis of egg weight, egg yolk weight and egg albumen weight of bovan neva black laying hens at 25, 51 and 72 weeks. for this purpose, thirty birds were selected from the layer flock in the babcock university teaching and research farm. they were individually housed in separate labeled battery cage. a total of thirty eggs were collected...

BACKGROUND Several 3D multi-segment foot models (MFMs) have been introduced for the in vivo analysis of dynamic foot kinematics. However, reproducibility of a model should be checked and ascertained before clinical utilization of a MFM. The purpose of this study was to determine the reliability of recently introduced MFM with a 15-marker set by assessing the participant's stride-to-stride (intr...

Selection of body sway parameters according to their sensitivity and repeatability For the precise evaluation of body balance, static type of tests performed on a force plate are the most commonly used ones. In these tests, body sway characteristics are analyzed based on the model of inverted pendulum and looking at the center of pressure (COP) movement in time. Human body engages different str...
