Evaluation Of The Distribution Of Taguchi's Signal-To-Noise Ratio And The Effectiveness Of The Signal-To-Noise Ratio For Detecting Changes In The Mean And/Or Variance, Jinsuk Lee

Masters Theses

The concept of parameter design developed by Taguchi to achieve robust engineering is widely promoted in industry as a means to design a product whose output is largely immune to noise in the system. Taguchi has used the signal-to-noise (S/N) ratio to summarize measures over the noise factor settings at the parameter design and to allow control of the experiment.

The objectives of this investigation are: 1) to infer distributions of S/N ratios (lower-the-better S/N, higher-the-better S/N, and nominal-the-best SIN), and 2) to determine the effectiveness of the S/N ratio as a means for identifying changes in the mean and …

Performance & Project Spirit Of Student Design Competition Teams, Bradley Marcus Davis

Masters Theses

"Student design competition teams present a valuable research possibility in the field of work group research. They are widely available and present greater learning opportunities than do class project groups. This study intended to create an instrument to measure the level of project spirit and team performance in order to establish a link between these two concepts. In the present study, nine student design competition teams from the University of Missouri - Rolla (UMR) campus (n = 186) were surveyed. The results indicate a strong correlation of the project spirit variables (project culture, project commitment, project citizenship, and project satisfaction) …
