Engineering Education Quality Assurance

With the rapid globalization of higher education as well as related changes in social, political, economic, and other conditions over the last 25 years there have been ever increasing expectations for higher education, in general, and Engineering Education, in particular. These expectations are often expressed in terms of the need for Quality Assurance locally, regionally, and globally. In some cases, there is a long tradition of independence and self-regulation of higher education institutions and programs. In other contexts, there has been c- siderable governmental regulation and disciplinary direction over time. The authors in this volume represent essentially all continents and 15 different countries. The common issues that they raise and their accounts of past, present, and future ch- lenges provide a snapshot of the current state of Quality Assurance in higher edu- tion and Engineering Education. This volume begins with an overview of the history and background of Quality Assurance in higher education and Engineering Education over the last century. The discussion of the historical, philosophical, political, and social background of Quality Assurance sets the stage for the other chapters. Following this broad brush stoke introduction, in the next part of the book, authors describe the general issues and challenges facing Quality Assurance in the twenty-first century from both regional and national perspectives. These authors have extensive experience in the area of Quality Assurance and have observed its growth and develop first hand over many years.

Chemical Oscillations and Instabilities

Today, scientists in many fields are expressing considerable interest in non-linearity and the ideas of oscillations and chaos. Chemical reactions provide perfect examples of these phenomena. This book is an excellent introduction to the area of nonlinear phenomena in chemical kinetics thatinvolve chemical feedback such as chain branching, autocatalysis, and self-heating. The emphasis is on physical and pictorial representation, and on identifying those gross features which are essential. The experimental conditions under which such behavior will occur can be predicted using simplemathematical recipes, and these are also included. Readers will find full discussions of long-lived oscillations for autocatalytic or exothermic reactions in closed vessels and stationary states, bistability, and oscillations in continuous flow reactors and diffusion cells. Other topics consideredinclude chemical wave propagation, pattern selection and formation, heterogeneous reactions, complex oscillations, quasiperiodicity, and chemical chaos, both forced and spontaneous. The second part of the book describes actual experimental systems, such as the Belousov-Zhabotinskii reaction, andinclude discussion of the behavior of important gas-phase reactions. This volume is an ideal sourcebook of applied problems for graduate courses in dynamical systems, advanced chemical kinetics, and chemical reactor engineering, as well as for research workers in physical chemistry, andmathematicians, biologists, physicists, and physiologists.
