Fear of heights and visual height intolerance
Current Opinion in Neurology, 2014The aim of this review is, first, to cover the different aspects of visual height intolerance such as historical descriptions, definition of terms, phenomenology of the condition, neurophysiological control of gaze, stance and locomotion, and therapy, and, second, to identify warranted epidemiological and experimental studies.Vivid descriptions of fear

Sitting height and sitting height/height ratio references for Turkish children
European Journal of Pediatrics, 2014Sitting height (SHt) measurements and sitting height/height (SHt/Ht) ratio are important criteria in the diagnosis of growth problems and particularly in the diagnosis of dysproportionate growth. It is known that body proportions are related to genetic influences and show variations among different populations.

On the Height of Multidimensional Height-Balanced Trees
IEEE Transactions on Computers, 1986It is shown that the worst case height of a k-dimensional height-balanced tree, \(k\geq 2\), is the same as that of an AVL-tree, to within an additive factor of 2k-2.

Periodica Mathematica Hungarica, 2003
The naive height \(H(\alpha)\) of an algebraic number \(\alpha\) is defined to be the maximum of the absolute values of the coefficients of its minimal polynomial. Define the metric height of \(\alpha\) by \(\widehat{H}(\alpha) = \inf \{H(\alpha_1) \cdots H(\alpha_s)\}\), where the infimum is taken over all \(s \geq 1\) and all algebraic numbers ...

The heights for the time measurement and the time for the heights measurement
2018 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2018Measuring the time is something essential to humans: all our activities are marked by atomic clocks found in research laboratories, in companies and in many satellites above us. In this context, a common International Time scale has been necessary for several centuries.

The association of body height, height variability and inequality
Anthropologischer Anzeiger, 2016Body height is associated with environmental conditions. It has been suggested that under poor conditions when inequality within a population increases, also the variability in height tends to increase. We studied the association of body height, within-country variability in height and geographic and historic origin in 767 growth studies carried out in

Human Factors: The Journal of the Human Factors and Ergonomics Society, 2000
We examined the influence of backrest inclination and vergence demand on the posture and gaze angle that workers adopt to view visual targets placed in different vertical locations. In the study, 12 participants viewed a small video monitor placed in 7 locations around a 0.65-m radius arc (from 65° below to 30° above horizontal eye height).

Final height, target height and the community.
Georgian medical news, 2014Height varies with age, and it varies with historic time. Final height is determined by endocrine parameters and genetics, by nutrition and health, by environmental factors, by birth weight, early growth, BMI, and developmental tempo. European populations of the 19th century were short, but their shortness did not result from growth impairment at all ...
