Achieving the promise of e-business Two divergent approaches exist in purchasing and supply management organizations today, which give at least the perception of conflicting direction: 1. Some organizations, counseled by consultants and e-procurement software suppliers, but without a clear understanding of current actual procurement processes, have implemented expensive systems with the expectations of tremendous savings and spectacular supply chain improvements. The results often haven’t lived up to the claims. 2. Many buyers and purchasing managers, failing to grasp the potential benefits from e-procurement, have resisted change, and not given their full support to system improvements. Those who have delayed have missed the opportunities of vastly improved processes and supplier contributions. Both have valid viewpoints, but neither has delivered on the true promise of supply chain improvements, so the lessons of this book should benefit both. Active supporters of e-procurement can benefit from understanding the “nuts and bolts” approach to the fundamental supply management processes in a global context. Moreover, buyers and their managers with a better vision of the future will be better prepared to adapt to and support the needed changes.
A Guide to the Evaluation of IntegralsSpecial Integrals of Gradshetyn and Ryzhik: The Proofs provides self-contained proofs of a variety of entries in the frequently used table of integrals by I.S. Gradshteyn and I.M. Ryzhik. The book gives the most elementary arguments possible and uses Mathematica® to verify the formulas. Readers discover the beauty, patterns, and unexpected connections behind the formulas.Volume I collects 15 papers from Revista Scientia covering logarithmic integrals, the gamma function, trigonometric integrals, the beta function, the digamma function, the incomplete beta function, Frullani integrals, and various combinations. The book presents entries without indicating the range of parameters for their validity, encouraging readers to determine this range themselves. Many entries have a variety of proofs that can be evaluated using a symbolic language or point to the development of a new algorithm.
