A shear force on the skin, perpendicular to the forces applying pressures, is thought to be a contributing factor to the formation of decubitus ulcers . The gage described here has been designed to give some quantitative information about the extent of shear forces that exist between human skin and a support medium. The basic operating principle of the device is the measurement of relative moti...

The WSR-57 radar a t Sacramento provides an opportunity to observe mountain effects on precipitation and on radar echo patterns. Radar patterns representing a wide range of weather situations are described and interpreted in light of concurrent gage precipitation measurements. The frequent underestimation by radar of rainfall on windward slopes is attributed to the small drop size and low forma...

The time interval between initiation of surface convergence and the subsequent response of visible cloud growth to this convergence was examined for nine cases of convection that occurred over the FACE 1973 and 1975 mesonetworks in south Florida. Clouds ranged in size from small echoes with a few towers to merged lines or large clusters of towers, but they met a series of observational criteria...

Modified least squares method (LSM) is developed that take into account errors in input standard signals for calibration of measuring devices. Calibration of the differential pressure gage by the standard control-point setting mechanisms is demonstrated in the paper as an example. The accuracy of the coefficient estimates changes when the errors of the control-point setting mechanisms are taken...
