This book examines current practices in assessment of learning and accountability at a time when accrediting boards, the federal government and state legislatures are requiring higher education to account for such outcomes as student retention, graduation, and learning.

An excellent introduction to inviscid airflow using potential theory, this book is a classic in its field. Complete reprint of the revised 1966 edition, which brings the subject up to date.

Modern Exterior Ballistics is a comprehensive text covering the basic free flight dynamics of symmetric projectiles. The book provides a historical perspective of early developments in the 19th century, the technology leading to World War I and that through World War II into the modern post-war era. Historical topics include the first ballistic firing tables, early wind tunnel experiments, the development of free flight spark ranges and the first supercomputer, ENIAC, which was designed to compute artillery trajectories for the U.S. Army Ballistic Research Laboratory. The level of the text requires an undergraduate education in mathematics, physics, and mechanical or aerospace engineering. The basic principles of ballistic science are developed from a comprehensive definition of the aerodynamic forces that control the flight dynamics of symmetric projectiles. The author carefully starts with the basic vacuum point mass trajectory, adds the effects of drag, discusses the action of winds, simple flat fire approximations, Coriolis effects and concludes with the classic modified point mass trajectories. Included in the discussion are analytical methods, change of variables from time to distance, numerical solutions and a chapter on the Siacci Method. The Siacci Method provides a historical perspective for computing flat fire trajectories by simple quadrature and is used in the sporting arms industy. The final six chapters of the book present an extensive physical and mathematical analysis of the motion of symmetric projectiles. The linearized equations of angular and swerving motion are derived in detail. The effects of mass asymmetry, in-bore yaw, cross wind and launch in a slipstream are discussed. Special consideration is given to the derivation and explanation of aerodynamic jump. These subjects are then expanded to include a complete chapter on nonlinear aerodynamic forces and moments. The final chapter in the book presents an overview of experimental methods for measuring the flight dynamics of projectiles. The great forte of Modern Exterior Ballistics is the author's effort to provide many fine specific examples of projectile motion illustrating key flight behaviors. The extensive collection of data on projectiles from small arms to artillery used to substantiate calculations and examples is alone a valuable reference. The ultimate joy of the book is the incomparable comprehensive set of flow field shadow graphs illustrating the entire spectrum of projectile flight from subsonic, through transonic and supersonic. The volume is a necessary addition to any undergraduate or graduate course in flight dynamics.

We are delighted to present the proceeding of the 4th International Conference on Accounting, Management, and Economics (ICAME – 2019) held on 25th October 2019 in Makassar, Indonesia. ICAME is an annual agenda of the Faculty of Economics and Business Universitas Hasanuddin. The rapid advancement in the business industry in the industrial revolution 4.0 era brings significant challenges not only to the business environment but also to university as higher education institutions to produce graduates who are able to compete globally as well as to adapt with changes in technology development. This is the background of ICAME – 2019 theme which is “Enlightening Research Paradigm in Business and Economics beyond Industrial Revolution 4.0”. The purpose of this conference is to produce qualified research and publications which is in turn expected to be referenced in solving society issues. In addition, this event is a forum to establish a network among academicians and business practitioners to encourage the growth of innovation and creativity in the field of Accounting, Management, and Economics. The conference invited academicians, students, and business practitioners to participate in the Call for Paper to share their research results. Therefore, we are pleased to present this proceedings of the conference.
