Information on tree height is useful for volume estimation and site productivity assessment as such, remains one of the most important variables often measured in forest inventories. Measuring a sufficient number sample trees requires considerable sampling effort cost. In this study, we developed functions optimizing measurement Swedish long-term experiments (LTFEs). Two large datasets from LTF...

INTRODUCTION The Third National Health and Morbidity Survey Malaysia 2006 includes a nutritional status assessment of children. This study aimed to assess the inter- and intra-examiner reliability, the technical error of measurement and the validity of instruments for measuring weight, height and waist circumference. METHODS A convenience sample of 130 adults working in a selected office sett...

The purpose of this study is the definition and conception of a measurement system capable of continuously determining the level of carbon type bulk products, stored in a large-sized tank (mine shaft). This storage system has several supply circuits and a tapping circuit using motorized conveyor belts. The measurement system, associated with a data processing procedure, makes it possible to est...

A comprehensive error analysis was performed on the impulse method. To evaluate the potential errors, jump height was recalculated after altering one of the measurement or calculation techniquaes while leaving the others unchanged, and then comparing it to the reference jump height (best estimate of true jump height). Measurement techniques introduced the greatest error. Low-pass filters with c...

In many centres, height is used as a determinant for calculating predicted body weight. This predicted body weight is then multiplied to generate the desired tidal volume. The approach exhibits some mathematical effects: (1) any errors in height measurement are multiplied by 5.5 when generating the tidal volume (assuming 6 ml/kg); (2) any errors in height measurement have a greater impact on sh...

This paper presents the performance analysis of Bistatic Interferometer BAsed on Spaceborne SAR (BIBASS). As a bistatic system with general configuration, the system response of BIBASS is azimuth/range dependent. Taking into account this peculiarity, the appropriate theoretical framework is developed to make a more accurate evaluation of the performance of BIBASS. Firstly, the interferometric f...

This study explores global inequality in health status and decomposes it into within- and between-country inequality. We rely on standardized height as our health indicator since it avoids the measurement pitfalls of more traditional measures of health such as morbidity, mortality, and life expectancy. It also avoids measurement problems associated with using monetary variables such as income o...
