Abstract Spin injection from ferromagnet into nonmagnetic semiconductor is theoretically investigated for the case when the electric current in ferromagnet/semiconductor structure depends on time. The study of switching on/off dc current showed that the time dependence of the magnetization at any point inside semiconductor does not obey the ...

How are storm time injections different from nonstorm time injections?
Journal of Atmospheric and Solar-Terrestrial Physics, 2004Abstract One of the key elements of storms and substorms is the injection of energetic particles into the region of near geosynchronous orbit, that is, the sudden flux enhancement in the energy range of tens to hundreds of keV. This paper reports the observational results on how such injection features during storm times are different from those of ...

Injection locking of punched-through-injection transit-time oscillators
Proceedings of the IEEE, 1973Injection-locking experiments have been conducted with the punched-through-diode oscillator, and the results have agreed well with theory. This confirms the nature of oscillations to be of a negative-resistance type and not of a relaxation type.

TIME DELAY FOR INJECTION SPRAYERS
Transactions of the ASAE, 1998Lag times were measured for one boom section of an inline injection sprayer system. Lag time is defined as the time period between when an injected pesticide rate changed and when the new pesticide rate reached nozzles on the boom. Lag time factors investigated were: number of active nozzles, boom size, travel speed changes, and pesticide viscosity.

An injection/circulation-timing switch for angiography
Albrecht von Graefes Archiv f�r Klinische und Experimentelle Ophthalmologie, 1978An injection/circulation-timing switch was developed to simply and precisely initiate the timing unit of the fundus camera for angiographic documentation. After starting the timer, the switch, mounted on the syringe used for injection of the tracer material, subsequently provides documentation of the total elapsed time of injection.

Real-time locally injective volumetric deformation
ACM Transactions on Graphics, 2021We present a highly efficient method for interactive volumetric meshless shape deformation. Our method operates within a low dimensional sub-space of shape-aware C ∞ harmonic maps, and is the first method that is guaranteed to produce a smooth locally injective deformation in 3D ...
