Critical Height Sampling for Stand Volume Estimation
Forest Science, 1985Abstract Critical height sampling as a technique for estimating stand volume without using volume tables is explained. Based on point sampling for tree selection, the stand volume estimator is the product of the point sampling basal area factor and the sum of critical heights of trees in the sample.

Optical remote sensing of tree and stand heights
2015Ce chapitre explique dans un premier temps pourquoi les mesures de hauteur des arbres sont si importantes en écologie et pour les gestionnaires forestiers. Il présente ensuite deux techniques de télédétection, le lidar et la photogrammétrie numérique, qui peuvent être utilisées pour étendre ces mesures (qui sont fastidieuses par des approches de ...

Prediction of the pubertal growth spurt by measurement of standing height
The European Journal of Orthodontics, 1983A method of predicting the onset of pubertal growth spurt is described. It is based on growth records of 105 children and requires the routine measurement of standing height. The method identifies a point in a patient's development which anticipates the occurrence of the peak in height velocity.

A comparison between various definitions of forest stand height and aerodynamic canopy height
Agricultural and Forest Meteorology, 2010A consistent measure of forest canopy height is required for among-site comparisons of meteorological properties and for comparison of model results such as distributions of wind and other scalars calculated by large eddy simulations with observations.

Mapping the Zone of Eye-Height Utility for Seated and Standing Observers
Perception, 2000In a series of experiments, we delimited a region within the vertical axis of space in which eye height (EH) information is used maximally to scale object heights, referred to as the “zone of eye height utility” (Wraga, 1999b Journal of Experimental Psychology, Human Perception and Performance25 518–530).

Influence of Head Height on Arterial Blood Pressure in Standing Horses
American Journal of Veterinary Research, 1980SUMMARY Eighteen horses were used to investigate the influence of head position on arterial blood pressure, measured indirectly at the coccygeal artery. Head height significantly altered systolic pressure, diastolic pressure, pulse pressure, and mean arterial pressure, such that head-lowering decreased and head-raising increased all variables.

The need to accommodate monitor height changes between sitting and standing
Ergonomics, 2019Recently, the rate at which sit-to-stand workstations are being introduced into the workplace has seen a dramatic increase. Aside from adjusting the height of the desk when transitioning from sitting to standing, there is a lack of literature regarding the necessary adjustments to other equipment associated with the workstation.

Biparietal Thinning: Accidental Death by a Fall from Standing Height
Journal of Forensic Sciences, 2017AbstractBiparietal thinning resulting in bilateral and symmetrical resorption and loss of thickness of the parietal bones is an uncommon to rare condition in the anthropological and clinical literature. This enigmatic condition of unknown etiology was first reported in the 18th century and has been variously described as a nonmetric trait, anatomical ...

[Relations of standing height, sitting height and weight of male Americans].
Anatomischer Anzeiger, 1985Based on log/log graphs correlating weight with standing and sitting height of U.S. Americans as given by Altman and Dittmer (1962) allometric relations between both heights are tested and found to give relatively good results. With lacking dates of age the standing and sitting heights can only be put in loose time junction by comparison with the ...

Shoot height, weight and standing crop in relation to density of monospecific plant stands
Nature, 1979DESPITE great differences in architecture and supporting tissue, monospecific stands of single-stemmed plants ranging in size from a moss to a tree follow a simple rule relating shoot dry weight and standing crop to density. We describe here an equation for this relationship which remains true for almost any fully occupied plant stand dominated by a ...
