In the process of writing this manual, we have incurred many debts of gratitude. The deepest, without question, are to our wives, Sanny Chan and Cornelia Bica, not only for tolerating with good cheer our extended absences from the home during the twelve-month period over which the manual was prepared, but also for carefully poring over the chapters and finding errors that had eluded the authors and all of the other accuracy checkers. Our wives, above all others, are glad to see the ordeal end and normal family life return. We must commend Dr. David Shim for the tremendous effort he put into thoroughly checkingeach and every solution in the manual. Put simply, David Shim's comments and correctionswere invaluable to us. Also lending enormous assistance was Dr. Ralph Petrucci. During the course of the project, weasked Dr. Petrucci innumerable questions, some of a highly complex nature, and, each and every time, he expeditiously fired us back a comprehensive answer. Hats off to you Ralph for a job well done!Some help with proofreading and keying in corrections was provided by Dr. Dusan Ristic-Petrovic. We thank Dr. Geoff Hemng for providing us with a solution to Question 87 in Chapter P 12. We are grateful to Kristen Kaiser and John Chalice at Prentice Hall for their help and encouragement throughout the enterprise.Any errors or misinterpretations contained in this manual are solely our responsibility. We have done our best to make this manual error free, but because of its great size and complexity, some errors undoubtedly have gone undetected. Any errors that come to light will, of course, be dealt with during the next round of corrections.Finally, we would like to extend a very special thanks to the administration of Grant MacEwan College for allowing us to use the college's in-house computing and printing facilities to prepare the this manual.
