The creation of new semi-interpenetrating polymer networks (semi-IPNs) was attempted using miscible blends of high molecular weight cellulose esters (CE) and low molecular weight polyvinylphenol (PVP) with various initiators for the crosslinking reaction. Blends of cellulose acetate (CA) or cellulose acetate butyrate (CAB), at 50/50, 70/30, and 90/10 wt%CE/wt% PVP...
The quest to achieve reliable communication has always existed. Error Correcting
codes have made communication systems even more reliable under high
signal to noise ratios. A new class of codes called Turbo codes have proved to be
more effective compared to the other classes of codes and achieve performance close...
The metallurgy and superconductivity of the Nb-Ti-Ta ternary alloy system were studied.
The Nb-Ti, and Ta-Ti binary samples, and Nb-Ti-Ta ternary samples were precipitation
heat treated under different schedules. After the precipitating heat treatment, the samples
were characterized by X-Ray Diffraction (XRD) techniques. Equilibrium binary and
ternary phase diagrams based...
This work sets forth a reformulation of Levins' loop analysis for the qualitative
modeling of complex dynamical systems. Relationships between members of ecological
communities can be analyzed through a qualitatively specified community matrix,
whereby +1, -1, or 0 represent effects of one species upon another. A contribution is made to...
