It is our conviction that professional skill in forestry will develop more readily and more efficiently if forestry students are presented with a clear understanding of the im- pact of the physical factors that both enhance and inhibit forestry activities. Part I is analytic, written as a basic text for undergradu- ates in courses such as logging, transport, forest engineer- ing and even forest management. It deals with the fundamen- tals of technology in forestry as determined by the physical environment. The analytic approach serves two purposes, to bring about a clear understanding of the...

The purpose of this book is to provide students, practicing engineers and scientists with a treatment of nonlinear phenomena occurring in physical systems. Although only mechanical models are used, the theory applies to all physical systems governed by the same equations, so that the book can be used to study nonlinear phenomena in other branches of engineering, such as electrical engineering and aerospace engineering, as well as in physics. The book consists of two volumes. Volume I is concerned with single- degree-of-freedom systems and it presents the fundamental concepts of nonlinear...

Dieser Band enthlUt die Vortrage, die wahrend des Intemationalen KoHoquiums aus Anlass des 50. Todesjahres von Edmund Husserl und des 50-jahrigen Bestehens des Husserl-Archivs yom 21. bis 24. September 1988 in Leuven 1 gehalten wurden. Edmund HusserI starb am 27. Apri11938 und am 21. Septem ber desselben Jahres unterzeichnete H.L. Van Breda mit Frau Malvine Husserl einen Vertrag, der die Voraussetzung filr die Oberfilhrung des umfangreichen Nachlasses aus Nazi-Deutschland nach Belgien erm6glichte. Am 28. Oktober 1938 steHte die Leuvener Universitat Rliumlichkeiten und finanzieHe Mittel zur...

Nowadays, the engineering practice raises far more vibration problems than can be theoretically explained or modelled. Because Df this, measurements are used in almost all fields of industry, transportation and civil engineering in studies of mechanical and structural vibration. They are an invaluable tool for designing products and machines with high reliability and low noise level, vehicles and buildings with improved comfort and resistance to dynamic loads, as well as for obtaining increased safety of opera tion and optimum running parameters. In order to cope with the increasing demand...

Combining experts from the medical and materials sciences, the Institute considered current concepts in medical and materials sciences as they relate to implantable prostheses in orthopedic surgical practice. The syllabus included theory and applications of materials properties, physiological function, and host response to metal and non-metal materials. Total hip prostheses are the most common orthopedic device implanted today involved in over 200,000 operations. Failures occur at the rate of 10~-40~ at ~ to 10 years. Failures are due to loosening, infection, fracture of femoral components,...

This book is based on a number of lectures presented at CISM* -Course on "Stochastic Methods in Structural Mechanics", August 28 -30,1985 in Udine, Italy. The chapters presented here are either expanded and/or updated versions of these lectures. The purpose is to introduce readers to basic principles of stochastic methods of structural mechanics, particularly to those of dynamics. For those readers who wish to pursue the study further, the references provided in each chapter will serve as a useful source of information. Nevertheless the readers find some of the advanced topics presented by...

The first volume addresses the fundamental concepts used in the treatment of single-degree-of-freedom systems. Subjects covered include the mathematical model of the system, stability of motion, and the principal approximate analytical methods used to describe both harmonic and non-harmonic oscillat
