A study was undertaken to assess the value of symphysis-fundus measurement as a screening procedure for intrauterine growth retardation. The reproducibility of this measurement was investigated in two groups of six patients, each measured six times by six different observers. The intraobserver coefficient of variation was 4.6% and the interobserver coefficient of variation 6.4%. There was no ev...

Arm span and standing height were measured in 289 boys and 337 girls aged 6-15 years who were free from physical deformities which can affect stature or arm span. The arm span exceeded height in all age groups of boys and in older girls. At the age of 7, 11 and 12 years girls were significantly taller than the boys and had longer arm span while at the age of 15 years, the trend was opposite. Th...

Changes in vertical larynx position during singing were studied in professional singer subjects using the two-channel electroglottograph recently presented by Rothenberg (1992). The evaluation of the method and the examination of the laryngeal behaviors of professionnl singers were the main aims of the study. The significance of pitch, vocal loudness and lung volume to vertical larynx position ...

This paper introduces a novel approach for performing non-invasive particle size analysis for a material stream running on a standard conveyor belt. The measurements, carried out with a 3D laser scanner and a measuring belt weigher, are accurate, robust and real world physical measures. The 3D data obtained with the laser scanner enables more accurate analysis than the spatial monochrome or col...

antitussive or expectorant activity. Cough can also be reported in terms ofits intensity, loudness, duration, pressure, flow and volume relationships, cough “resistances” can be calculated to reflect the inertial, elastic and flow-resistive components of respiration, and changes in breathing mechanics in the upper and lower airways may be recorded.’ Under the same sponsorship as the Charlottesv...

OBJECTIVES to examine differences between measured height and demi-span equivalent height (DEH) among people aged >or=65 and investigate the impact on body mass index (BMI) of using DEH. DESIGN AND SETTING nationally representative cross-sectional sample of adults living in England. PARTICIPANTS 3,346 non-institutionalised adults aged >or=65, taking part in the Health Survey for England (HS...

Light Detection And Ranging (LiDAR), is a system of laser detection and distance measurement installed on aircraft or satellites. Because of its high angular resolution, high range resolution and anti-jamming characters, the objects heights on the earth surface can be acquired precisely with LiDAR. In forestry application, LiDAR with spot size smaller than 1m can acquire thousands of laser poin...

Introduction: The validity of Body Mass Index (BMI) based on self-reported height and weight is of critical importance in the proper assessment of studies that rely on questionnaire-derived data. In this study, we evaluate the accuracy of adolescent overweight and obesity classification bpased on self-reported height and weight factors and propose a regression model for predicting the true BMI....

background: anthropometry is a branch of ergonomics that considers the measurement and description of the human body dimensions. accordingly, equipment, environments, and workstations should be designed using user-centered design processes. anthropometric dimensions differ considerably across gender, race, ethnicity and age, taking into account ergonomic and anthropometric principles. the aim o...

Managing road assets, such as roadside curbs, is one of the interests of municipalities. As an interesting application of computer vision, this paper proposes a system for automated measurement of the height of the roadside curbs. The developed system uses the spatial information available in the disparity image obtained from a stereo setup. Data about the geometry of the scene is extracted in ...
