On November 16th, COSMOS Ph.D. student Bancha Ariyajunya successfully defended his dissertation, entitled “Adaptive Dynamic Programming for High-Dimensional, Multicollinear State Spaces.” His dissertation committee included COSMOS faculty Dr. Victoria Chen, Dr. Jay Rosenberger, and Dr. Li Zeng. His dissertation addressed the problem of correlated variables in a dynamic programming state space. His methodology was originally motivated by airport deicing activities and was tested on an ozone pollution control optimization. In airport deicing, the state of the system considers the environmental impact of deicing, and the environmental variables are highly correlated. In ozone pollution, the state of the system considers ozone concentrations in the air, and these are highly correlated over time and space. Bancha’s research was supported by grants from the National Science Foundation and the Dallas-Fort Worth International Airport. His current research interest is in the area of statistical modeling and data mining.

On October 18, COSMOS Ph.D. student Poovich Phaladiganon successfully defended his dissertation entitled “Data Mining Based Threshold Development for Novelty Detection.” His dissertation committee included COSMOS faculty Victoria Chen, Li Zeng, Bill Corley, and Korea University Professor Seoung Bum Kim, who made a special trip to UTA for Poovich’s defense. In addition to Poovich’s Ph.D., he has an M.S. degree also in Industrial Engineering from UTA and has worked as a Graduate Teaching Assistant. His current research interests are multivariate statistical process control and novelty detection. Upon defending his dissertation, Poovich said, “It is a great experience to be a part of the COSMOS society. I have learned about both academics and life along my road to a doctorate.”
