Indirect torque measurement methods can be performed in a variety of ways, depending on the specific situation and available tools. One such way is to measure displacement, or speed rotation shaft use this information calculate moment using inertia equation. For this, it necessary know angular acceleration, which measured gyroscope accelerometer. Another voltage current electrical circuit conne...

A technique for measuring the voltage dependent capacitance of pixels by using a low cost integrated circuit and some common laboratory equipments is proposed. The error in measurement ranges from 1 to 2% and this technique can be used for indirect measurement of various parameters of the liquid crystals.

1. Direct intra-arterial blood pressure (radial artery) has been compared with indirect blood pressures using a regular sized adult cuff and a thigh cuff, with a mercury sphygmomanometer, in 24 hypertensive patients aged 62--84 years, and in 16 hypertensive patients aged 29--59 years. 2. The patients were studied because they were suspected of having a false elevation of their indirect blood pr...

BACKGROUND To evaluate the agreement between cranial and facial classification obtained by clinical observation and anthropometric measurements among school children from the municipality of Envigado, Colombia. METHODS This cross-sectional study was carried out among 8-15-year-old children. Initially, an indirect clinical observation was made to determine the skull pattern (dolichocephalic, m...

This study assessed the accuracy of indirect blood pressure (BP) measurements by simultaneously performing three kinds of indirect BP measurement on the left arm (auscultatory, microphone and oscillometric methods) and a direct BP measurement on the left arm. The subjects were 34 hospitalized patients, ranging in age from 18 to 73 years (average 47.5 years). Highly significant correlations in s...

BACKGROUND Due to physiological and cognitive changes that occur with aging, accurate physical activity (PA) measurement in older adults represents a unique challenge. The primary purpose of this study was to systematically review measures of PA and their use and appropriateness with older adults. A secondary aim was to determine the level of agreement between PA measures in older adults. MET...
