Abstract: We made an experimental investigation of the motions of the retainer in an instrument ball bearing during stable operation and during squeal. Radial motions of the retainer were measured with ...

Abstract: A stepwise multilevel scheme is developed to sequentially calibrate infiltration and roughness parameters for free-draining furrow irrigation systems. The scheme is one dimensional at each level, thereby simplifying ...

Abstract: Rational evaluation of surface irrigation systems should consider the effects of spatial variations in soil intake properties on advance trajectories and on the uniformity of infiltrated depths. The objective was to quantify ...

Abstract: Simulation of aggregate water demands by areas commanded by canal and lateral turnouts is an important input to the operation and management of the irrigation delivery system. A computer simulation model to predict these ...

Abstract: The cumulative water demand (CWD) curve was used for validating and calibrating the unit command area (UCA) model, which predicts the aggregate water demands of individual command areas for the entire crop season. During ...

Abstract: The Federal Water Pollution Control Act, which later became the Clean Water Act, handles pollution from industrial and commercial discharges differently from dredge and fill pollution associated with waterway maintenance ...

Abstract: The behavior of corner bays of flat plate floors was investigated in 11 tests of slabs on four columns. The performance of each specimen is described and related to the details of the slab‐column joints. Comparisons are ...
