Introduction

Neural networks have received a great deal of attention among scientists and engineers. In chemical engineering, neural computing has moved from pioneering projects toward mainstream industrial applications. This book introduces the fundamental principles of neural computing, and is the first to focus on its practical applications in bioprocessing and chemical engineering. Examples, problems, and 10 detailed case studies demonstrate how to develop, train, and apply neural networks. A disk containing input data files for all illustrative examples, case studies, and practice problems provides the opportunity for hands-on experience. An important goal of the book is to help the student or practitioner learn and implement neural networks quickly and inexpensively using commercially available, PC-based software tools. Detailed network specifications and training procedures are included for all neural network examples discussed in the book.

Chapter Structure and Content

Each chapter contains an introduction, chapter summary, references to further reading, practice problems, and a section on nomenclature. Includes a PC-compatible disk containing input data files for examples, case studies, and practice problems. Presents 10 detailed case studies. Contains an extensive glossary, explaining terminology used in neural network applications in science and engineering.

Applications and Case Studies

Provides examples, problems, and ten detailed case studies of neural computing applications, including:

• Process fault-diagnosis of a chemical reactor
