Accuracy of self-reported height measurements in parents and its effect on mid-parental target height calculation
BACKGROUND Clinical determination of mid-parental height is an important part of the assessment of a child's growth, however our clinical impression has been that parents cannot be relied upon to accurately report their own heights. Therefore, we conducted this study to assess the accuracy of parental height self-reporting and its effect on calculated mid-parental target height for children pre...
متن کاملOn the use of ICESAT-GLAS measurements for MODIS and SEVIRI cloud-top height accuracy assessment
This study reports on the first attempt to use cloud boundary and optical depth retrievals from the GLAS lidar to assess the accuracy of cloud-top heights obtained with MODIS (onboard NASA-TERRA and AQUA) and SEVIRI (onboard METEOSAT-8). Over the period from 25 September to 18 November 2003, MODIS-GLAS coincidences were only found in the Polar Regions, whilst SEVIRI-GLAS coincidences were avail...
متن کاملAccuracy and precision of measurements obtained from conventional cephalograms and CBCT scan in orthodontics linear diagnostic measurements
Background and Purpose: Due to the important role of imaging in the diagnosis and treatment plan in orthodontics, CBCT (Cone Beam Computed Tomography) images because of their three-dimensional nature, can minimize the disadvantages of two-dimensional images such as magnification, distortion, or superimposition. The purpose of this study was to evaluate the accuracy of conventional cephalograms...
متن کاملThe Accuracy of Jitter Measurements
Jitter is a variation in a waveform’s timing. The timing variation of the period, duty cycle, frequency, etc. can be measured and compared to an average of multiple periods, or can be measured as a variation from one period to the next. A jitter measurement result will typically consist of a count of the number of periods evaluated over the selected time interval, a measurement of the highest v...
متن کاملAccuracy of acoustic rhinometry measurements.
OBJECTIVES To identify the factors that influence the accuracy of acoustic rhinometry measurements recorded with commercially available equipment. STUDY DESIGN A simple model was used which consisted of a metal pipe and cylindrical inserts. These inserts comprised various lengths, and aperture dimensions were comparable to, or smaller than, the nasal valve areas of both adults and children. ...
