Body Mass Index is associated with endurance performance in athletes. Reported and measured values of body mass and body height in 1,618 endurance athletes (1,358 men, 260 women) showed that men and women both underestimated their body mass and overestimated their body height, leading to an underestimation of Body Mass Index. There were age and sex differences in estimates of height and weight;...

We extend an existing virtual reality terrain visualization framework to support spatial analysis tasks for geoscientific purposes. We demonstrate both interactive measurement of height profiles as well as volume measurement within polygonal footprints. In this application, virtual reality technology enables superior perception of the placement of these lines with respect to terrain features.

BACKGROUND Undernutrition is an important risk factor for childhood mortality, and remains a major problem facing many developing countries. Millennium Development Goal 1 calls for a reduction in underweight children, implemented through a variety of interventions. To adequately judge the impact of these interventions, it is important to know the reproducibility of the main indicators for under...

AIM To monitor the growth of 5 to 11 year old English and Scottish children from 1972 to 1994. No similar data are available from any other study. DESIGN Mixed longitudinal. SUBJECTS In England 7000 children were sampled in the first year, falling to 5000. In Scotland the original sample was 2000 but this was enlarged later to 3500. MAIN OUTCOME MEASUREMENTS Height, weight, weight for hei...

BACKGROUND The key to its successful application is to determine the best entry point for the vertebral screw(s). This study aimed to provide a reference for clinical anterolateral fixation through digital measurement of computed tomography (CT) data to identify relevant anatomical positions in the middle and lower thoracic vertebrae (T4-T12) of 30 adults. MATERIAL AND METHODS We performed digi...

This report presents STRUCTVIEW, a vehicle-based system for the measurement of roadway structure profiles, which uses a scanning laser rangefinder to measure various structure and roadway features while traveling at highway speed. Measurement capabilities include horizontal and vertical clearances which can be used to support issuing permits based on vehicle height.

We have recently performed a systematic review which collated seventy eight cross-sectional and prospective studies exploring waist-to-height ratio and waist circumference or body mass index as predictors of diabetes and cardiovascular disease published in English between 1950 and 2008. This review, which also employed specificity and sensitivity comparisons, indicated that waist-to-height rati...

Smoke plume height is important formodelling smoke transport and resulting effects on air quality. This study presents analyses of ceilometer measurements of smoke plume heights for twenty prescribed burns in the south-eastern United States. Measurements were conducted from mid-winter to early summer between 2009 and 2011. Approximately half of the burns were on tracts of land over 400 ha (1000...

Airborne measurement of the horizontal pressure field using differential GPS technology has been established during the last few years. Accurate aircraft measurement of the horizontal pressure gradient force requires an independent determination of the height of the airborne platform above some reference level. Here the authors demonstrate a differential GPS technique that uses data from a fixe...
