We revisit the reactor antineutrino anomaly using the recent reactor flux independent determination of sizable 13 by considering the full set of the absolute reactor e flux measurements. When normalized to the predicted flux of Mueller et al. [Phys. Rev. C 83, 054615 (2011)], the new world average, after including results from Palo Verde, Chooz, and Double Chooz, is 0:959 0:009 (experiment unce...

The Atlantic Meridional Overturning Circulation (AMOC) is an important component of ocean thermohaline circulation. Melting of Greenland's ice sheet is freshening the North Atlantic; however, whether the augmented freshwater flux is disrupting the AMOC is unclear. Dense Labrador Sea Water (LSW), formed by winter cooling of saline North Atlantic water and subsequent convection, is a key componen...

Motivated by observed anomalous features in cycle 23, as inferred from records of photospheric magnetic flux, we develop a flux transport dynamo–based scheme in order to investigate the physical cause of such anomalies. In this first study we focus on understanding anomalies occurring in the polar field evolutionary pattern in cycle 23, namely, why the polar reversal in cycle 23 was slow, why a...

[1] The one-dimensional model of Rudnicki and Chen [1988] for a slip-weakening dilating fault is extended to include shear heating. Because inertia is not included, instability (a seismic event) corresponds to an unbounded slip rate. Shear heating tends to increase pore pressure and decrease the effective compressive stress and the resistance to slip and consequently tends to promote instabilit...

The permanent magnet brushless DC motor (BLDCM) is typically controlled using the six-step commutation method, and flux-weakening method employed to enable operate at speeds higher than base speed. Currently, it considered that weak magnetic angle range 0-pi/3, while for deep weakening pi/3-pi/2. In field-weakening control, a forward shift of point results in circulating current flowing three-p...

This article proposes a flux-weakening (FW) control for dual three-phase permanent magnet synchronous machine (DTPMSM) based on vector space decomposition (VSD) control, where the output voltage in ?? subplane is employed feedback FW loop.

Permanent magnet machines have been used in the high-speed drive applications due to their high-efficiency, high-power-density, and wide-speed range characteristics. However, control of such permanent machine is always challenging proper flux-weakening controller design essential achieve high performance these machines. In this paper, an improved feedforward scheme for interior synchronous (IPM...
