Preparation of a semi-interpenetrating polymer network using cellulose esters and polyvinylphenol

Creator:

Gaibler, David W.

Abstract:

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...

Complexity and performance analysis of turbo decoders for wireless communication systems

Creator:

Rangarajulu, Suresh

Abstract:

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...

Metallurgy and superconductivity of niobium-titanium-tantalum ternary alloy systems

Creator:

Li, Na

Abstract:

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...

Qualitative analysis of the community matrix

Creator:

Dambacher, Jeffrey M.

Abstract:

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...
