An unfortunate result of this attempt to show the intersection of life and art is a diminishment of the dark imagination of the artist: it is not a profound vision of human suffering and limitations that produces the dark currents of Oates's work but instead the working out of "traumas"- some rather few incidents that pale in comparison with those of innumerable humans, living or dead, and indeed with the sufferings of Oates's own fictional characters.
Although there are dark currents present (a painting on the wall behind her is of the mythical Last Judgment), the soft source of light from a high window and her quiet concentration suggest an affirmation to her mysterious measuring; she is absorbed in one of those moments when peacefulness and musings reign to a deep and feeling degree.
This may force the researchers to measure dark currents every few days rather than once a month, Hester says.
Past experience indicates that this should dramatically reduce the variability of dark current and lower the top-to-bottom variation of the CCDs.
34] Although the details of how this layer impacts the performance of CCDs have not been fully investigated, many devices demonstrated transfer of charge at frequencies as low as 1 MHz, which indicates that dark currents are very low.
The Model 6482's 2nA current measurement range is ideal for measuring dark currents and other low currents with 1fA resolution.
Still, the first-time helmer stumbles at times, playing parts of the pic too broadly--the woman-and-dog subplot has a sitcom feel that undercuts some of the pic's dark currents.
Handel says this theory is strongly supported by past experiments and can provide a mechanism for the dark currents.
35um CMOS we can provide sensitivities and very low dark currents that meet leading edge industry requirements at very attractive prices.
Hall at the Institute for Astronomy, University of Hawaii, demonstrated mean detector dark currents for (lambda)co = 5.
