TL;DR: In this article, a non-combustion flavor-generating article uses electrical energy to power a heating element which heats tobacco or other flavorants, and the energy delivered to the heating element is regulated to maintain the flavorgenerating medium at a relatively constant operating temperature.
Abstract: Methods and apparatus for releasing flavor components from a flavor-generating medium using an electric heating element are provided. A non-combustion flavor-generating article uses electrical energy to power a heating element which heats tobacco or other flavorants. The flavor-generating medium is formed into a packed bed. Energy delivered to the heating element is regulated to maintain the flavor-generating medium at a relatively constant operating temperature to ensure a relatively constant release of flavor.

TL;DR: In this paper, the numerical modeling of reset programming in NiO-based resistive-switching memory is addressed, and it is shown that reset transition is self-accelerated as a consequence of a positive feedback between the thermal dissolution of the conductive filament and local Joule heating in the CF bottleneck.
Abstract: This paper addresses the numerical modeling of reset programming in NiO-based resistive-switching memory. In our model, we simulate electrical conduction and heating in the conductive filament (CF), which controls the resistance of the low resistive (or set) state, accounting for CF thermal-activated dissolution. Employing CF electrical and thermal parameters, which were previously characterized on our NiO-based samples, our calculations are shown to match experimental reset and retention characteristics. Simulations show that reset transition is self-accelerated as a consequence of a positive feedback between the thermal dissolution of the CF and local Joule heating in the CF bottleneck, which can account for the abrupt resistance transition in experimental data. Finally, the model is used to investigate the reduction of the reset current, which is needed for device application.

TL;DR: In this article, the authors reviewed the results from confinement scaling experiments on tokamaks with strong auxiliary heating and made an attempt to draw these results together into a low-density ohmic confinement scaling law, and a scaling law for confinement with auxiliary heating.
Abstract: Recent results from confinement scaling experiments on tokamaks with ohmic and strong auxiliary heating are reviewed. An attempt is made to draw these results together into a low-density ohmic confinement scaling law, and a scaling law for confinement with auxiliary heating. The auxiliary heating confinement law may also serve to explain the saturation in tau/sub E/ vs anti n/sub e/ observed in some ohmic heating density scaling experiments.

06 Apr 1984TL;DR: In this paper, an electrical heater containing spoolable, steel sheathed, mineral insulated cables was used to heat underground earth formations at a substantially uniform rate of more than about 100 watts per foot at temperatures between about 600° and 1000° C, with a pattern of localized electrical resistances which are correlated with the heat conductivities of the earth formations and the heat stabilities of materials providing power and support for the heater.
Abstract: Long intervals of subterranean earth formations are heated at high temperatures for long times with an electrical heater containing spoolable, steel sheathed, mineral insulated cables which have high electrical conductivities, enabling them to heat the earth formations at a substantially uniform rate of more than about 100 watts per foot at temperatures between about 600° and 1000° C., with a pattern of localized electrical resistances which are correlated with the heat conductivities of the earth formations and the heat stabilities of materials providing power and support for the heater.
