Anthony A. Ruffa serves as the Director of Research at the Naval Undersea Warfare Center (NUWC), Newport, RI, USA. He is responsible for managing the development and execution of a portfolio of Office of Naval Research (ONR) funded projects that forms the foundation of NUWC's science and technology (S&T) competency, and works with the Navy research community to identify emerging technologies and assess the maturity and risks of current technologies. Dr. Ruffa has published research papers in many diverse areas of mathematics and physics (including the original paper on the generalized method of exhaustion that forms the basis of this monograph), and holds 76 U.S. Patents.Bourama Toni is a Full Professor of Mathematics and Chair of the Department of Mathematics at Howard University, Washington, DC, USA; and Founder and Editor of the Springer-published STEAM-H series, with truly an interdisciplinary profile. Dr. Toni's research interests are primarily in Differential and Nonlinear Analysis and related topics to include Dynamical Systems, Non-Archimedean Analysis, Game Theory, Feedback Loops Analysis, and their applications to biosciences, behavioral sciences and naval engineering, with an excellent track-record of quality published research papers including contributed volumes with Springer.
