PURPOSE Functional Reach Test scores were examined for the effects of traditional and alternate methods and subject characteristics. METHODS Eighty subjects aged 7 to 16 years were tested. Effects of measurement method (from finger-to-finger or from toe-to-finger) and style of reach (1 or 2 arms) were investigated. Five subject variables were analyzed for interactions among the methods and gr...

Height is one of the most important dimensions of trees, but few observers are fully aware of the consequences of the misapplication of conventional height measurement techniques. A new approach, the sine method, can improve height measurement by being less sensitive to the requirements of conventional techniques (similar triangles and the tangent method). We studied the sine method through a c...

BACKGROUND AND OBJECTIVES Estimation of GFR in children from serum creatinine measures in regional databases is limited by a lack of height data. Furthermore, the ability of GFR estimating equations to quantify changes in GFR over time is unknown. Two methods of estimating GFR when height is unknown and the ability of several GFR equations to quantify GFR changes over time were evaluated. DES...

Triangulation method, conoscopic holography method and interferometry method are analyzed for effective measurement of micro burr geometry, which is formed in micro drilling. To select proper sensor, cylinder with 0.5mm diameter is measured and the result shows that conoscopic holography method is effective for measuring highly inclined surface. Burr with 1.0mm height and 30μm height are measur...

Periodic measurements of plant height could be used to calculate growth rate and have potential for characterizing spatial variation of plant response to inputs and field conditions. A corn plant height measurement system using stereo machine vision was developed. A test apparatus was developed, which consisted of an x-y translating sensor platform with a CCD camera and an imaging stage for cam...

For this purpose, a SICK LMS 291 LIght Detecti...

BACKGROUND The causes of the "dual burden" of stunting and obesity remain unclear, and its existence at the individual level varies between populations. We investigate whether the individual dual burden differentially affects low socioeconomic status Peruvian children from contrasting environments (urban lowlands and rural highlands), and whether tibia length can discount the possible autocorre...
