Considering that the verification phase is usually performed based on the peak velocity or power attained at the incremental test, protocols with longer or less steep stages followed by submaximal verification phases could end up using intensities below the critical power for some subjects.
The check whether it is possible to use the 2005-look up table primary designed for heated pipes also for heated rod bundles gives the surprising result that the bundle critical power for five data sets of three different bundles and different power distributions are predicted by a simple method described above using the 2005-look up table within the accuracy reported by the authors of this table.
During ophthalmic surgery large numerical apertures are advantageous because the threshold irradiance for optical breakdown can already be surpassed at lower pulse energies (considering laser powers below the critical power for self-focusing) [ 5].
This is a legitimate concern when dealing with microjoule, low numerical aperture beams, for example, since the peak powers for these beam conditions often exceed the critical power for self-focusing, especially when employing pulse energies well above the threshold for damage.
At focusing conditions with numerical apertures NA ≤ 0.9 [ 28], which is generally the case in ophthalmic applications especially in the posterior eye segment, the pulse peak power required for optical breakdown is higher than the critical power for self-focusing [ 8, 29], therefore self-focusing is present.
In addition, the phenomenological based dryout modeling for the determination of thermal margins in BWR requires spacer model to be incorporated for evaluating the critical power of a fuel assembly.
But Mr. Kim's most concerted efforts seem to be directed at the military, the critical power base for his son.
The ability to operate highly efficient, pollution-free, distributed-generation power plants on either natural gas or HD-5 grade propane is of interest to the U.S. Army and the U.S. Department of Homeland Security as secure power for critical power operations.
A method for determining critical power spectral density matrix models for earthquake excitations which maximize steady response variance of linear multiply supported extended structures and which also satisfy constraints on input variance, zero crossing rates, frequency content and transmission time lag has been developed.
Justice Stevens is irreplaceable for many reasons, not the least of which is a critical power he has held for the last 17 years as the Court's most senior justice.
