Nowadays, most nuclear weapons are implosion types.
The other major assembly method is implosion, in which a subcritical mass of fissile material is compressed by a chemical high explosive into a denser critical mass.
Thus, we make the following definitions: Define the window (textbf {W}^{K}_{k}) to be an implosion window if S k =0; Define the sequence {x k } to be an implosion sequence if all windows are implosion windows (i.e., if S k =0 for all k); Define the sequence {x k } to be implosion-free if it contains no implosion windows (i.e., if S k >0 for all k).
Define the window (textbf {W}^{K}_{k}) to be an implosion window if S k =0; Define the sequence {x k } to be an implosion sequence if all windows are implosion windows (i.e., if S k =0 for all k); Define the sequence {x k } to be implosion-free if it contains no implosion windows (i.e., if S k >0 for all k).
This damage, ahead of the armoured bulkhead, could have been implosion damage suffered while Hood sank, as a torpedo room that had been removed during one of her last refits approximates the site of the break.
Thus, the signals of greatest interest in characterizing Hampel filter performance are implosion-free sequences that are not median filter roots.
Finally, it is important to note that, for the filter window width considered here (K=5), the signal sequence shown in Fig. 1 is implosion-free and is not a median filter root sequence.
Included in this selection are: implosions in planar, cylindrical, and spherical coordinates, piston problems with a variety of mesh configurations including the difficult Saltzman problem, interacting blast waves, and a spherical expansion on a rectangular mesh.
Social conservatives lost ballot initiatives on everything from abortion to gay marriage.Why the conservative crack-up The obvious crack-up The right's implobviouss the implosion of the Bush presidencause
The underlying reason was the implosion of liberal America.
