The purpose of this research was to evaluate consumer response based on two distances (12 and 24 inches) between tables in a fast-casual restaurant. An onsite survey was conducted to measure customers’ cognitive, emotional, and behavioral responses to questions on pleasure, privacy, stress, arousal, comfort, control, customer satisfaction, and future dining intentions based on their experience with the table spacing. Results showed that table spacing has an effect on diner’s pleasure, feelings of privacy, and sense of comfort and control. The results confirmed a strong correlation between customer satisfaction and future behavioral intentions.

This dissertation studies the design of an efficient adaptive digital baseband predistorter for modern cellular handsets that combines low power consumption, low implementation complexity, and high performance. The proposed enhancements are optimized for hardware implementation. We first present a thorough study of the optimal spacing of linearly-interpolated lookup table predistorters supported by theoretical calculations and extensive simulations. A constant-SNR compander that increases the predistorter's supported input dynamic range is derived. A corresponding low-complexity approximation that lends itself to efficient hardware design is also implemented in VHDL and synthesized with the Synopsys Design Compiler. This dissertation also proposes an LMS-based predistorter adaptation that is optimized for hardware implementation and compares the effectiveness of the direct and indirect learning architectures. A novel predistorter design with quadrature imbalance correction capability is developed and a corresponding adaptation scheme is proposed. This robust predistorter configuration is designed by combining linearization and I/Q imbalance correction into a single function with the same computational complexity as the widespread complex-gain predistorter.
