Optical potential for antikaon-nucleus strong interactions are constructed using
elementary antikaon-nucleus potentials determined previously. The optical potentials
are used to determine the existence of a kaon hypernucleus. Modern three
dimensional visualization techniques are used to study model dependences, new
methods for speeding the calculation of the optical potential are developed,...
The parameters of separable coupled channels s-wave potentials for the strong
KN interaction are determined from low energy K⁻p scattering data with
additional constraints from π⁻p π∑K° production data. The shifts and
widths of the Coulomb bound states in kaonic hydrogen are calculated with
these potentials and compared with experiment....
The objective of this thesis is to develop and
computationally test a new algorithm for the class of
network models with generalized upper bound (GUB) side
constraints. Various algorithms have been developed to
solve the network with arbitrary side constraints problem;
however, no algorithm that exploits the special structure
of...
Linear transformation for dimension reduction is a well established problem in the field of machine learning. Due to the numerous observability of parameters and data, processing of the data in its raw form is computationally complex and difficult to visualize. Dimension reduction by means of feature extraction offers a strong...
The bulk of the theory on error control codes has been developed under the
fault assumption of random (symmetric) errors, where 1 → 0 and 0 → 1 errors are
equally likely. In the past few years, several applications have emerged in which the
observed errors are highly asymmetric. This...
We have developed SearchPak, a machine independent parallel searching tool on shared and distributed memory machines. It can be used for combinatorial optimization problems and OR-parallel computations as well. Both depth-first and best-first search of the state space can be performed using the SearchPak. With SearchPak, a user just provides...
This thesis develops a model for locating field offices for the
Motor Vehicles Division of Oregon. The locations are determined by
minimizing the total cost to the Public. This is reasonable because
the Public finances the operation and the opening of the offices
through tax dollars, and it bears the...
The objective of this investigation is the development
of improved techniques for the estimation of robustness for
dynamic systems with structured uncertainties, a problem
which was approached by application of the Lyapunov direct
method. This thesis considers the sign properties of the
Lyapunov function derivative integrated along finite intervals
of...
