Control of propulsion systems for supersonic cruise aircraft
The propulsion control requirements of supersonic aircraft are presented. Integration of inlet, engine, and airframe controls is discussed. The application of recent control theory developments to propulsion control design is described. Control component designs for achieving reliable, responsive propulsion control are also discussed

Numerical Simulations of N=(1,1) SYM{1+1} with Large Supersymmetry Breaking
We consider the SYM theory that is obtained by dimensionally
reducing SYM theory in 2+1 dimensions to 1+1 dimensions and discuss soft
supersymmetry breaking. We discuss the numerical simulation of this theory
using SDLCQ when either the boson or the fermion has a large mass. We compare
our result to the pure adjoint fermion theory and pure adjoint boson DLCQ
calculations of Klebanov, Demeterfi, and Bhanot and of Kutasov. With a large
boson mass we find that it is necessary to add additional operators to the
theory to obtain sensible results. When a large fermion mass is added to the
theory we find that it is not necessary to add operators to obtain a sensible
theory. The theory of the adjoint boson is a theory that has stringy bound
states similar to the full SYM theory. We also discuss another theory of
adjoint bosons with a spectrum similar to that obtained by Klebanov, Demeterfi,
and Bhanot.Comment: 12 pages, 4 figure
R-parity-violating SUSY and CP violation in B --> phi K_s
Recent measurements of CP asymmetry in B --> phi K_S appear to be
inconsistent with Standard Model expectations. We explore the effect of
R-parity-violating SUSY to understand the data.Comment: Equations corrected. Conclusions unchanged. Latex, 6 pages, one fi
meson transparency in nuclei from resonant interactions
We investigate the meson nuclear transparency using some recent
theoretical developments on the in medium self-energy. The inclusion of
direct resonant -scattering and the kaon decay mechanisms leads to a
width much larger than in most previous theoretical approaches. The
model has been confronted with photoproduction data from CLAS and LEPS and the
recent proton induced production from COSY finding an overall good
agreement. The results support the need of a quite large direct -scattering contribution to the self-energy
