Study on Zero Crossing Detection in CRM Totem-pole PFC Converter
… Based on an understanding of the delay mechanism, ZCD delay compensation techniques are discussed and compared. Second, the coupling mechanism of dv/dt switching noise as common-mode noise in the ZCD circuit is analyzed. Upon understanding this coupling mechanism, a shielding technique …

The design and construction of a laboratory facility for the measurement of reactor moderator parameters
… blocks in each foil channel is facilitated by a coupling mechanism. Five source positions permit operation with reduced harmonics. The neutron distribution in the pile was proven to be symmetric by horizontal and vertical traverses. By means of a diffusion length measurement, which gave an "L” of …

Experimental methods to examine the role of vibrational excitation in the singlet-triplet spin-orbit coupling in acetylene
… has been observed to have a complex spin-orbit coupling mechanism where the first excited singlet state S couples to the triplet state T3 which is then coupled to the dense manifold of vibrational states in the T, 2 electronic states. A description of theories imperative to this study is …

Phase planes in the universe : chaotic cyclic universes and kicking Chameleons
… in the early universe, unless constraints on its coupling mechanism are significantly increased. It is shown that the addition of a Dirac-Borne-Infeld (DBI) correction - a consistent, high energy modification - to the Chameleon dynamically renders it weakly coupled to matter. This is done without …

Passive harmonic generation at spring contacts
… second paper, we show that the maximum E-field coupling occurs at a location slightly offset from the trace center. The E-field coupling to a shielded H-field probe at such a position leads to differential mode coupling which the standard shield of an H-field probe is unable to suppress. The …
