Characterization and modeling of aperiodic pressure oscillations in combustion chambers
Classification of the long-term dynamical
behavior of pressure oscillations in a
laboratory combustion chamber has been
performed using methods of modern dynamical
systems theory. The method involves the
construction of a phase-space representation
from a single pressure record or time series using
the time-delay embedding method. The
pointwise correlation dimension of the resulting
attractor in phase-space provides a lower
bound on the number of modes that participate
in the oscillations. The results show that the
oscillations are quasiperiodic with a dimension
near two over an order of magnitude of
amplitudes. Quasiperiodicity is a result of the
incommensurate frequencies of the system
acoustic modes. A model for the dynamics is
constructed by converting the governing
equations to a kicked-oscillator model. When
compared with the experimental data, the
model results have similar pressure and
velocity spectra and the attractor dimension
verifies that quasiperiodic oscillations are
present
The Utility of Naturalness, and how its Application to Quantum Electrodynamics envisages the Standard Model and Higgs Boson
With the Higgs boson discovery and no new physics found at the LHC,
confidence in Naturalness as a guiding principle for particle physics is under
increased pressure. We wait to see if it proves its mettle in the LHC upgrades
ahead, and beyond. In the meantime, in a series of "realistic intellectual
leaps" I present a justification {\it a posteriori} of the Naturalness
criterion by suggesting that uncompromising application of the principle to
quantum electrodynamics leads toward the Standard Model and Higgs boson without
additional experimental input. Potential lessons for today and future theory
building are commented upon.Comment: 7 pages, no figure

Premises for Reforming the Regulation of Securities Offerings: An Essay
Cox discusses six fundamental tenets that should guide the regulation of public offerings of securities. It is assumed that regulation is to be re-examined from the ground up, with no political or regulatory constraints
