A constrained weighted recursive least squares method is proposed to provide recursive models with guaranteed stability and better performance than models based on regular identification methods in predicting the variations of blood glucose concentration in patients with Type 1 Diabetes. Use of physiological information from a sports armband improves(More)
A novel meal-detection algorithm is developed based on continuous glucose measurements. Bergman's minimal model is modified and used in an unscented Kalman filter for state estimations. The estimated rate of appearance of glucose is used for meal detection. Data from nine subjects are used to assess the performance of the algorithm. The results indicate(More)
— Recursive time series models can describe effectively and accurately complex systems with time-varying parameters. These simple models can be used in forecasting and control systems. However, these models may be unstable because of plant and measurement noise even when the process is known to be stable. In this paper, we propose an approach to guarantee(More)
ii This dissertation is dedicated to: my loving husband, Maveni Palu, who provides endless support and sacrifice so that I may realize my dreams; our precious daughters, Olivia and Oreina, who are constant reminders of life's true joys as well as the fulfillment and happiness attained through curiosity, discovery, and everyday enlightenment; and my parents,(More)
