Next: Tests Using a Up: Model Updating in the Previous: Model Updating . By virtue of the MU technique, in order to achieve some critical value for data fitting, not only the number of outer iterations but also the number of inner iterations in each outer iteration is reduced. ... Even in this case, and would be two solutions that are not equal because the ``solution space'' (a set formed by all the possible solutions) without model updating is different from that with model updating. ...

... The trapping regions of high-energy charged particles surrounding the Earth are called radiation (or van Allen) belts (Van Allen et al., 1958; Van Allen and Frank, 1959). The inner one, located between about X = 1.1 - 3.3 Re (Earth radii, geocentric) in the equatorial plane, contains primarily protons with energies exceeding 10 MeV. ... The radiation belts are of importance primarily because of the harmfull effects of high energy particle radition for man and electronics: . ...

... 12a. Inner Belt . ... The inner radiation belt, discovered by Explorers 1 and 3, owes its existence to the extraordinary stability of trapped orbits near the Earth. ... If these are electrically charged, e.g. electrons or ions, they will often end up trapped by the Earth's magnetic field. ... The energetic protons which then materialize are grabbed by the Earth's magnetic field, often on trapped orbits which do not return to the atmosphere, in which the proton can stay trapped for a rather long time...

Describes how spatial region boundaries are handled. The golden rule for spatial region filtering was first enunciated by Leon VanSpeybroeck in 1986: . ... With this in mind, the rules for determining whether a boundary image pixel or table row are assigned to a region are defined below. For image filtering, pixels whose center is inside the boundary are included. ... That is, an row is inside the boundary without regard to its integerized pixel value. ...

... LWN.net FAQ . ... Read-copy-update (RCU) is a mutual exclusion technique which can operate without locking most of the time. It can yield significant performance benefits when the data to be protected is accessed via a pointer, is read frequently, changed rarely, and references to the structure are not held while a kernel thread sleeps. The core idea behind RCU is that, when the data requires updating, a pointer to a new structure containing the new data can be stored immediately. ...

The determination of the detector parameters is based on sets of images of a spatially uniform-illumination scene (flatfield frames) and without any illumination (dark frames), putting a plug in place of the filter, taken at a series of exposure times. ... We interleave before and after each exposure time in the series of flatfield frames a set of reference images at an exposure time of 1 sec to determine the possible temporal variation of the illumination level. ...
