Summary:
Hadamard matrices in their various guises arise many times in
the study of reliable communications and secure communications. The aim of this
research project is to use the theory of cyclotomy in both fields and rings
to find new number theoretic results which will then be used to obtain new with
zero or small autocorrelation functions. The significance of this research is
to propose new construction of Hadamard matrices and block designs for computer
security and wireless network communication. We expect some new classes of Hadamard
matrices and block designs can be constructed for security and communication
applications and several papers would be submitted or published.

Summary:
The technology of superconducting wires and tapes has emerged
as one of the most important basic engineering technologies, which can create
technical innovation and improvement in the quality of life in the fields of
electric power, energy, machinery, transportation and the environment in the
21st century. The aim of the proposed program is to develop magnesium diboride
superconductor and YBCO coated conductors by using novel nano-precursor powders.
Superconducting tapes doped with nano-sized powders are expected to show enhancement
in flux pinning properties. The expected outcome is the capability to produce
a new generation of superconductors having high performance at low cost.
