Fundamentals of Fluid Film Lubrication
Specifically focusing on fluid film, hydrodynamic, and elastohydrodynamic lubrication, this edition studies the most important principles of fluid film lubrication for the correct design of bearings, gears, and rolling operations, and for the prevention of friction and wear in engineering designs. It explains various theories, procedures, and equations for improved solutions to machining challenges. Providing more than 1120 display equations and an introductory section in each chapter, Fundamentals of Fluid Film Lubrication, Second Edition facilitates the analysis of any machine element that uses fluid film lubrication and strengthens understanding of critical design concepts.
Piezoelectric Energy Harvesting
The transformation of vibrations into electric energy through the use of piezoelectric devices is an exciting and rapidly developing area of research with a widening range of applications constantly materialising. With Piezoelectric Energy Harvesting, world-leading researchers provide a timely and comprehensive coverage of the electromechanical modelling and applications of piezoelectric energy harvesters. They present principal modelling approaches, synthesizing fundamental material related to mechanical, aerospace, civil, electrical and materials engineering disciplines for vibration-based energy harvesting using piezoelectric transduction. Piezoelectric Energy Harvesting provides the first comprehensive treatment of distributed-parameter electromechanical modelling for piezoelectric energy harvesting with extensive case studies including experimental validations, and is the first book to address modelling of various forms of excitation in piezoelectric energy harvesting, ranging from airflow excitation to moving loads, thus ensuring its relevance to engineers in fields as disparate as aerospace engineering and civil engineering. Coverage includes: Analytical and approximate analytical distributed-parameter electromechanical models with illustrative theoretical case studies as well as extensive experimental validations Several problems of piezoelectric energy harvesting ranging from simple harmonic excitation to random vibrations Details of introducing and modelling piezoelectric coupling for various problems Modelling and exploiting nonlinear dynamics for performance enhancement, supported with experimental verifications Applications ranging from moving load excitation of slender bridges to airflow excitation of aeroelastic sections A review of standard nonlinear energy harvesting circuits with modelling aspects.
Vehicle Operating Costs

Release Date: 1987
This book provides information concerning the costs of transportation on non-urban highways and the relationships between these costs and characteristics of highways such as surface roughness, and vertical and horizontal geometry. The sources of the information presented here are four major road user cost studies performed between 1970 and 1982 in Kenya, the Caribbean, Brazil, and India. In these studies road user costs were investigated in considerable depth. Surveys of commercial road users were performed, surveys on a far larger scale than had been conducted prior to the 1970s. Large scale experiments were undertaken, aimed at determining the fuel consumption of cars, buses and light and heavy goods vehicles under alternative highway conditions, and considerable effort was devoted to obtaining data on vehicle speeds and their responses to highway conditions. The resulting body of knowledge concerning road users' costs is enormous, spanning three continents, diverse highway conditions and radically different economic environments.
