Abstract: Estimates of the root mean square change in density at 1, 7, 12, 18, and 25 km are presented for lags of one through 24 hours. The lag variability at all of the heights considered increased with an increase in time. The ...

Abstract: Temperature measurements within 200 mi of the airport, and for altitudes up to 60,000 ft, will be necessary for calculating the fuel requirements of supersonic transports. In order to determine an adequate time and space ...

Abstract: The relatively new concept of wave-based control is extended to general, finite-dimensional, linear, time-invariant systems, with or without damping. The new models offer an explanation for how systems of springs and masses ...

Abstract: As a preliminary phase in a predictive mass‐transport modeling study, ground‐water samples were collected from an unconfined, landfill‐contaminated aquifer over a five‐month time period. The dilution effect of recharge ...

Abstract: Merritt, B.C. has a history of suffering damages from ice-jam and open-water floods. The most damaging flood on record happened in the city in 1991 due to an ice jam on the Coldwater River. A numerical ice-jam model is ...

Abstract: Necessary and sufficient conditions for solving flow-constrained networks are developed. These conditions are predicated on the interrelation between the decision variables specified and the network-flow hydraulics. They ...

Abstract: This paper presents an experimental and computational study of the effect of severe inlet temperature distortion (hot streaks) on the efficiency of the MT1 HP turbine, which is a highlyloaded unshrouded transonic design. ...

Abstract: An explicit algorithm is presented for directly determining a variety of design, operating, and calibration parameters for pipe networks. The problem solution is based on the reformulation of the steady‐state network ...
