The purposes of this project are threefold. First, to ascertain how the Calderon test might be used in testing Iowa Type A asphaltic concrete mixes. Second, to determine whether or not the Calderon test may be correlated with the Iowa Stability, the Marshall Stability, or the Hveem Stability tests. Third, to establish, if possible, mix design crite

This study was concerned with the factors involved in the perception of depth from a binocular disparity. A binocularly observed configuration of constant convergences, constant visual size, and having constant binocular disparities was made to appear at two different distances in a monocularly observed field-of-view. Both the perceived frontoparal

A simple technique is presented for calibrating an electronic system used in the plotting of erythrocyte volume spectra. The calibration factors, once obtained, apparently remain applicable for some time. Precise estimates of calibration factors appear to be limited by errors in measuring hematocrit and/or mean channel. For consistent determination

The cat ciliary muscle was shown to respond to both parasympathetic and sympathetic nerve impulses in vitro. Sympathetic responses were directionally opposite to parasympathetic responses and are interpreted as active contractions of the radial muscle layer. Such contractions in the intact eye should result in accommodation of the eye for distant v

Measurements were made of the transient response of PDR-8 earphones. These data indicate that the original estimate of the onset-duration of auditory stimuli can be revised downward to 0.8 ms. Implicit in the results is a caveat on the faith one should have in the output of commonly used earphones with short- or single-transient inputs.
