Modern Tools to Perform Numerical Differentiation
The original direct differential quadrature (DQ) method has been known to fail for problems with strong nonlinearity and material discontinuity as well as for problems involving singularity, irregularity, and multiple scales. But now researchers in applied mathematics, computational mechanics, and engineering have developed a range of innovative DQ-based methods to overcome these shortcomings. Advanced Differential Quadrature Methods explores new DQ methods and uses these methods to solve problems beyond the capabilities of the direct DQ method.

After a basic introduction to the direct DQ method, the book presents a number of DQ methods, including complex DQ, triangular DQ, multi-scale DQ, variable order DQ, multi-domain DQ, and localized DQ. It also provides a mathematical compendium that summarizes Gauss elimination, the Runge-Kutta method, complex analysis, and more. The final chapter contains three codes written in the FORTRAN language, enabling readers to quickly acquire hands-on experience with DQ methods.

Focusing on leading-edge DQ methods, this book helps readers understand the majority of journal papers on the subject. In addition to gaining insight into the dynamic changes that have recently occurred in the field, readers will quickly master the use of DQ methods to solve complex problems.


The design and construction of the quantum computer is one of the most exciting and challenging goals of the scientific community. This book provides an introductory yet comprehensive treatment of the mathematical theory underlying quantum computation. The author adopts the formal, axiomatic style of stating and proving lemmas, propositions, and theorems, but does so in a way that keeps the treatment self-contained and accessible to a broad, multidisciplinary audience. Numerous diagrams of circuits and devices support the text. Plentiful exercises and examples reinforce the concepts and make this book suitable for graduate-level course work as well as a valuable reference for researchers and practitioners.
