... These are plugged into plug-plate holes drilled at the predicted locations of suitable guide stars in the field of view. ... In particular, any departure from the ideal elastic curve from the tubing anchor point to the hole appears to affect the rotation angle of the plug. ... No structure of the residual plug angle appeared significant when these data were examined in 3-D. Figure 3: The plug rotation angle has a standard deviation of 54њ (201њ peak-valley). ... How large can the rotation error be? ...

... Obviously, the size of the cavern is of the order of the Schwartzman radius. ... Thus, consideration of the inverse effect of pulsar radiation on the properties of accreting plasma makes the ejection possible even when the Schwartzman radius is smaller than the capture radius. ... If the cavern radius , the condition at its boundary can be written as . ... Apart from magnetic dipole radiation, the cavern may also contain relativistic particles (which are also reflected from the cavern boundary). ...

... We investigate the hydrodynamic stability of a relativistic flow of magnetized plasma in the simplest case where the energy density of the electromagnetic fields is much greater than the energy density of the matter (including the rest mass energy). ... Numerical calculations show that in the force-free approximation, the electron-positron jet with uniform poloidal magnetic field is stable for all velocities of longitudinal motion and rotation. ... The toroidal magnetic field is . ...

... For the first balloon flight of the Nuclear Compton Telescope (NCT) we have simultaneously reduced lowenergy background and enabled hard X-ray imaging by enshrouding the top of the instrument in a tin shield (bottom had BGO shielding), with part of the shield having strategically placed holes -- a 10% open coded aperture mask working up to 80 keV in conjunction with the finely pixellated double-sided Ge strip detectors. ... Key words: Compton telescope, coded mask, hard X-ray imaging, NCT. ...

Next: CONCLUSION Up: CHIRPLET TRANSFORM SUBSPACES Previous: Nondilational Chirplet Transform . Suppose we choose a windowed sinusoidal FM signal for our mother chirplet. Such a signal has a frequency that periodically rises and falls (much like the vibrato of musical instruments or the wail of a police siren). ... Figure 14 . ... Using the warbling mother chirplet, we also computed the ``dilation-dilation'' ( ) plane of the chirplet transform (Fig. 16 ) for the pendulum data. ...
