The Effect of MoS2 on Friction & Wear Behavior of PTFE Composites
The wear resistance of PTFE can be significantly improved by addition of suitable filler materials. Besides the type, the shape and size of the materials added also influence the tribological properties. In the past, research in this area has been confined to the PTFE filled with conventional filler materials like glass fibers, graphite, carbon fibers, etc. However, with the growing demand for utilizing PTFE in a variety of applications, significant effort is needed towards developing the novel composite materials by adding one or more non-conventional filler materials possessing the potential of increasing the wear resistance. It is established that PTFE exhibits significantly low coefficie...
VIBRATION AND NOISE REDUCTION IN PLANETARY GEAR TRAIN BY PHASING
Gears are essential parts of many precision power transmitting machines such as automobiles. The major functions of a gearbox are to transform speed and torque in a given ratio and to change the axis of rotation. Planetary gears yield several advantages over conventional parallel shaft gear systems: They produce high speed reductions in compact spaces, a greater load sharing, a higher torque to weight ratio, diminished bearing loads, and reduced noise and vibration. They are used in automobiles, helicopters, aircraft engines, heavy machinery, and a variety of other applications. Despite their advantages, the noise induced by the vibration of planetary gear systems remains a key concern. Planetary gears have received considerably less research attention than single mesh gear pairs. There is a particular scarcity of analysis of two planetary gear systems and their dynamic response. Hence, this book focuses on the study of two PGTs with different phasing (angular positions) while every individual set remains unchanged.

The Meaning of Nouns
Kaun&ddotu;abhatta's Vaiyakarana-bhusana is a massive work on semantic theory written in India in the 17th century. Kaun&ddotu;abhatta belonged to the tradition of Sanskrit grammar and in this work he consolidated the philosophy of language developed in the Paninian tradition of Sanskrit grammar. Kaun&ddotu;abhatta's work takes account of the philosophical debate which occurred in classical and medieval India among the philosophers and grammarians from about 500 B.C. to the 17th century A.D. Kaun&ddotu;abhatta's work primarily represents this debate between the traditions of Sanskrit grammar, Mi&mdotu;amsa, and Nyaya-Vaisesika. It discusses ontological, epistemological, and exegetical issues...
Planetary Gear Trains
This book provides comprehensive information for various planetary gear trains, with practical applications and comprehensive references to technical articles. In the text's chapters, readers can find all the information needed for various types of gear trains, with illustrations and examples. The authors help gear designers to creatively understand the design of gears, as well as master the mechanical calculations needed. Planetary Gear Trains is the most comprehensive and up-to-date work available in this key technical area. The book reflects not only teaching, but also the practical experience of the authors. It was developed under the motto "From practice to practice".
From Followers to Leaders
This book centres on the ways in which ordinary firms can improve technology management. It argues that succeeding as a follower-firm requires learning from many experiences and avoiding simplistic 'how-to' approaches.

A Guide to the World Bank
The World Bank Group is a vital source of financial and technical assistance to developing countries around the world. Its focus is on helping the poorest people in the poorest countries by using its financial resources, staff, and extensive experience to aid countries in reducing poverty, increasing economic growth, and improving quality of life. In partnership with more than 100 developing countries, the Bank Group is striving to improve health and education, fight corruption, boost agricultural support, build roadsand ports, and protect the environment. Other projects are aimed at rebuilding war-torn countries or regions, providing basic services such as access to clean water, and encoura...
Design of Mechanical Power Transmission
This second edition of Design for Mechanical Power Transmission contains more than twice the content of the original monograph. New materials include the addition of a chapter on Flexible Element Drives covering flat and v belt systems, chain link drives and an overview of CVT., more design example applications with solutions in all chapters, material on selecting commercially available transmissions and added case studies of matching power source to load requirements where performance characteristics vary with speed. In addressing the classic engineering problem of matching power source outputs to driven load requirements this revision continues to emphasize: modeling and analyzing the kine...
