Triggering the Hf Breakdown of the Atmosphere by Barium Release
RF ionization rates for mixtures of air with bariurn are computed using a Fokker-Planck code. It is shown that there is an optimum mixing ratio of barium to air, significantly ower than unity, which maximizes the ionization rate for a given value of incident RF power density and frequency. Rocket injection of barium at a selected height reduces ignificant/y the RF breakdown threshold for the mi...
متن کاملEffects of agriculture on wood breakdown and microbial biofilm respiration in southern Appalachian streams
1. Agriculture causes high sediment, nutrient and light input to streams, which may affect rates of ecosystem processes, such as organic matter decay. In the southern Appalachians, socioeconomic trends over the past 50 years have caused widespread abandonment of farmland with subsequent reforestation. Physical and chemical properties of streams in these reforested areas may be returning to pre-...
متن کاملTriggering BTeV
BTeV is a collider experiment at Fermilab designed for precision studies of CP violation and mixing. Unlike most collider experiments, the BTeV detector has a forward geometry that is optimized for the measurement of B and charm decays in a high-rate environment. While the rate of B production gives BTeV an advantage of almost four orders of magnitude over ee B factories, the BTeV Level 1 trigg...
متن کاملTriggering Scheduler
In this paper we present the performance analysis of two nite queues coupled by a triggering scheduler Customers waiting for service have rst to pass the scheduler and then experience service by their dedicated server The scheduler is permitted to gather a custo mer from a particular queue only if the corresponding server is idle An application of this model can be found in job shop like manufa...
متن کاملBreakdown analysis
It is a widely-supported tenet in human-computer interaction that the meaningful unit of analysis is not the technical device alone, but the technical device together with the person interacting with it; the reason is that what is a relevant property of a technology is only understandable with respect to the specific goals and resources activated during its usage. This basic reflection should a...
