This book addresses a range of solutions and effective control techniques for Microbial Fuel Cells (MFCs), intended as a response to the increased energy consumption and wastewater production stemming from globalization. It describes the fundamentals of MFCs and control-oriented mathematical models, and provides detailed information on uncertain parameters. Various control techniques like robust control with LMI, adaptive backstepping control, and exact linearization control are developed for different mathematical models. In turn, the book elaborates on the basics of adaptive control, presenting several methods in detail. It also demonstrates how MFCs can be developed at the laboratory level, equipping readers to develop their own MFCs for experimental purposes. In closing, it develops a transfer function model for MFCs by combining a system identification technique and model reference adaptive control techniques. By addressing one of the most promising sources of clean and renewable energy, this book provides a viable solution for meeting the world's increasing energy demands.

Conventional oral dosage forms provide a specific drug concentration in the systemic circulation without offering any control over the rate of drug delivery. Controlled-release drug delivery systems (CRDDS) provide drug release at a predetermined, predictable, and controlled rate. It was attempt to develop a gastro retentive drug delivery system of anti hypertensive drug using different polymers like that HPMCK4M, Xanthangum, PolyoxWSR303as matrixing agent, swelling agent, respectivel. A simplex lattice design was applied to combined effect of three formulation variables (ie, amount of HPMCK4M (X1), xanthangum (X2), and PolyoxWSR303 (X3). Results of multiple regression analysis indicated that low level of X1 and X 2 and high level of X3 should be used to manufacture the tablet formulation with desired in % swelling index and % drug release profile . When Polyox 303 was used, % swelling index increased, with increase on the total amount of drug released. Decreasing the amount of HPMC K4M while maintaining the total amount of polymer constant increased the release rate and total amount released. Decreasing the total amount of polymer decreases the swelling and work of penetration,
