PURPOSE The aim of this study was to evaluate the effect of polishing and glazing on the color and spectral distribution of monolithic zirconia. MATERIALS AND METHODS Forty-five monolithic zirconia specimens (16.3 mm × 16.4 mm × 2.0 mm) were fabricated and divided into 5 groups according to the number of A2-coloring liquid applications (Group I to V). Each group was divided into 3 subgroups a...
Tile responses of artificial neural networks to experimental and model generated inputs are compared for detection of damage in twisted fan blades using electronic holography. Tile training set inputs, for this work, are experimentally generated cllaracteristic pattenls of tile vibrating blades. Tile outputs are damage flag indicators or second derivatives of tile sensitivity vector projected d...
Buyer cooperatives, buyer alliances, and horizontal mergers are often perceived as attempts to increase buyer power. While prior theoretical and empirical work has emphasized that buyer size can increase buyer surplus, I show that even a small group of buyers with heterogeneous preferences can increase price competition among rival sellers by forming a buyer group and committing to buy exclusiv...
Relative to solar water heaters, solar air heaters have received relatively little investigation and have resulted in few commercial products.
