TL;DR: In this paper, the authors derived rate laws for transformations in which the new phase nucleates on grain boundary surface, grain edges, or grain corners, and in which a new phase grows with constant radial velocity.

TL;DR: The effects of couple stresses in fluids are considered in this paper, where a series of boundary value problems are solved to indicate the effects of the couple stresses as well as for experiments measuring the various material constants.
Abstract: The effects of couple stresses in fluids are considered. Linearized constitutive equations are proposed for force and couple stresses. A series of boundary‐value problems are solved to indicate the effects of couple stresses as well as for experiments measuring the various material constants. It is found that a size effect comes in which is not present in the nonpolar case (couple stresses absent).

02 Mar 1987TL;DR: In this paper, the half-bridge series resonant, parallel resonant and combination series-parallel resonant converters are compared for use in low output voltage power supply applications, and it is shown that the combination seriesparallel converter, which takes on the desirable characteristics of the pure series and the pure parallel converters, removes the main disadvantages of those two converters.
Abstract: The half-bridge series resonant, parallel resonant and combination series-parallel resonant converters are compared for use in low output voltage power supply applications. It is shown that the combination series-parallel converter, which takes on the desirable characteristics of the pure series and the pure parallel converter, removes the main disadvantages of those two converters. Analyses and breadboard results show that the combination series-parallel converter can run over a large input voltage range and a large load range (no-load to full-load) while while maintaining excellent efficiency. A useful analysis technique based on classical ac complex analysis is also introduced.

TL;DR: A method for adaptively optimizing the signal-to-noise ratio of an array antenna is presented and the relation of the adaptive array to sidelobe cancellation is shown, and a real-time adaptive implementation is discussed.
Abstract: A method for adaptively optimizing the signal-to-noise ratio of an array antenna is presented. Optimum element weights are derived for a prescribed environment and a given signal direction. The derivation is extended to the optimization of a "generalized" signal-to-noise ratio which permits specification of preferred weights for the normal quiescent environment. The relation of the adaptive array to sidelobe cancellation is shown, and a real-time adaptive implementation is discussed. For illustration, the performance of an adaptive linear array is presented for various jammer configurations.

TL;DR: In this article, a basic feedforward algorithm for executing this type of current vector torque control is discussed, including the implications of current regulator saturation at high speeds, and the key results are illustrated using a combination of simulation and prototype IPM drive measurements.
Abstract: Interior permanent-magnet (IPM) synchronous motors possess special features for adjustable-speed operation which distinguish them from other classes of ac machines. They are robust high powerdensity machines capable of operating at high motor and inverter efficiencies over wide speed ranges, including considerable ranges of constant-power operation. The magnet cost is minimized by the low magnet weight requirements of the IPM design. The impact of the buried-magnet configuration on the motor's electromagnetic characteristics is discussed. The rotor magnetic circuit saliency preferentially increases the quadrature-axis inductance and introduces a reluctance torque term into the IPM motor's torque equation. The electrical excitation requirements for the IPM synchronous motor are also discussed. The control of the sinusoidal phase currents in magnitude and phase angle with respect to the rotor orientation provides a means for achieving smooth responsive torque control. A basic feedforward algorithm for executing this type of current vector torque control is discussed, including the implications of current regulator saturation at high speeds. The key results are illustrated using a combination of simulation and prototype IPM drive measurements.
