Interaction of the westerlies with the Tibetan Plateau in determining the Mei-Yu termination [PDF]
, 2020 This study explores how the termination of the mei-yu is dynamically linked to the westerlies impinging on the Tibetan Plateau. It is found that the mei-yu stage terminates when the maximum upper-tropospheric westerlies shift beyond the northern edge of ...

Performance of Halbach magnetized brushless AC motors [PDF]
, 2003 The steady-state performance of Halbach magnetized brushless ac machines when operated in constant torque and flux-weakening modes is investigated both theoretically and experimentally, with particular emphasis on the influence of cross-coupling magnetic

Tropical Pacific influences on the North Atlantic thermohaline circulation [PDF]
, 2003 Most global climate models simulate a weakening of the North Atlantic Thermohaline Circulation (THC) in response to enhanced greenhouse warming. Both surface warming and freshening in high latitudes, the so-called sinking region, contribute to the ...

, 2015 Non-local thermodynamic equilibrium (NLTE) effects in diagnostically important solar Fe I lines are important due to the strong sensitivity of Fe I to ionizing UV radiation, which may lead to a considerable under-population of the Fe I levels in the ...

Strongly nonequilibrium flux flow in the presence of perforating submicron holes [PDF]
, 2005 We report on the effects of perforating submicron holes on the vortex dynamics of amorphous Nb0.7Ge0.3 microbridges in the strongly nonequilibrium mixed state, when vortex properties change substantially. In contrast to the weak nonequilibrium - when the

Improvement torque performances of interior permanent-magnet machines
CES Transactions on Electrical Machines and Systems, 2019 Due to their excellent efficiency, power density and constant power speed region, interior permanent-magnet (IPM) machines are very suitable for electric vehicles (EVs). This paper proposed a new IPM rotor topology, which can offer high reluctance torque,

Eruption of a Kink-Unstable Filament in Active Region NOAA 10696
, 2005 We present rapid-cadence Transition Region And Coronal Explorer (TRACE) observations which show evidence of a filament eruption from active region NOAA 10696, accompanied by an X2.5 flare, on 2004 November 10.
