The critical parts of a heavy duty engine are theoretically designed for infinite life without mechanical fatigue failure. Yet the life of an engine is in reality determined by wear of the critical parts. Even if an engine is designed and built to have normal wear life, abnormal wear takes place either due to special working conditions or increased loading. Understanding abnormal and normal wear enables the engineer to control the external conditions leading to premature wear, or to design the critical parts that have longer wear life and hence lower costs. The literature on wear phenomenon related to engines is scattered in numerous periodicals and books. For the first time, Lakshminarayanan and Nayak bring the tribological aspects of different critical engine components together in one volume, covering key components like the liner, piston, rings, valve, valve train and bearings, with methods to identify and quantify wear. <ul type="disc"> <li>The first book to combine solutions to critical component wear in one volume <li>Presents real world case studies with suitable mathematical models for earth movers, power generators, and sea going vessels <li>Includes material from researchers at Schaeffer Manufacturing (USA), Tekniker (Spain), Fuchs (Germany), BAM (Germany), Kirloskar Oil Engines Ltd (India) and Tarabusi (Spain) <li>Wear simulations and calculations included in the appendices <li>Instructor presentations slides with book figures available from the companion site
<i>Critical Component Wear in Heavy Duty Engines</i> is aimed at postgraduates in automotive engineering, engine design, tribology, combustion and practitioners involved in engine R&D for applications such as commercial vehicles, cars, stationary engines (for generators, pumps, etc.), boats and ships. This book is also a key reference for senior undergraduates looking to move onto advanced study in the above topics, consultants and product mangers in industry, as well as engineers involved in design of furnaces, gas turbines, and rocket combustion.

<i>Engineering Measurements – Methods and Intrinsic Errors</i> provides a valuable insight into the equipment and methods generally used in taking measurements, and helps engineers avoid or minimize the inaccuracies that can arise even when using highly accurate instruments. Many of the commonly used measurement methods are described, together with their pitfalls and problems. The authors also incorporate plenty of useful, practical examples. <p> Although there are a number of very good texts already available on the subject of engineering measurements, most are quite theoretical and few are written by practising engineers in industry. Those written by industrialists often concentrate only on their specific subject area. There does not appear to be a general text covering theoretical and practical aspects of engineering measurements, and in particular covering the areas of errors and pitfalls associated with taking these measurements. This book is designed to fill the gap, and incorporates knowledge obtained from years of practical experience in industry and R&D by the authors and the various contributors. <p> <i>Engineering Measurements – Methods and Intrinsic Errors</i> is highly readable, practical, and comprehensive. Any engineer involved in measurement, whether in manufacturing and process control, development, troubleshooting, or research, will find this guide a helpful everyday tool.
Metabolic and Cellular Engineering (MCE) is more than an exciting scientific enterprise. It has become the cornerstone for coping with the challenges ahead of mankind. Continuous developments, new concepts, and technological innovations will enable us to deal with emerging challenges, and solve problems once thought impossible ten years ago. Challenges in MCE are broad- from unraveling fundamental aspects of cellular function to meeting unsatiated energy and food demands that are rising in parallel with population growth.In charting the progress of MCE during the last decade, we could not help but feel in awe of the enormous strides of progress made from the nascent Metabolic Engineering to the Systems Bioengineering of today. The burgeoning availability of genomic sequences from diverse species has been spectacular. It has become the engine that drives the genetic means for the modification of existing organisms and the generation of synthetic, man-made ones. From the initial attempts at purposeful genetic modification of a cell for the production of valuable compounds, we have now moved on to changing microbes genetically or metabolically.The arsenal of experimental and theoretical tools available for Metabolic and Cellular Engineering has expanded enormously, driven by the re-emergence of Physiology as Systems Biology. The revival of the concept of networks fueled by new developments has become central to Systems Biology. Networks represent an integrative vision of how processes of disparate nature relate to each other, and as such is becoming a key analytical and conceptual tool for MCE. This book reflects and addresses all these ongoing changes while providing the essential conceptual and analytical tools needed to understand and work in the MCE research field.
This introduction to communication research methods takes the student from the conceptual beginnings of a research project through the design and analysis. Emphasizing the correct questions to ask and how to approach the answers, authors Gary Petty, Cheryl Campanella Bracken, and Elizabeth Babin approach social science methods as a language to be learned, requiring multiple sessions and reinforcement through practice. They explain the basics of conducting communication research, facilitating students' understanding of the operation and roles of research so that they can better critique and consume the materials in their classes and in the media.
The book takes an applied methods approach, introducing students to the conceptual elements of communication science and then presenting these elements in a single study throughout the text, articulating the similarities and differences of individual methods along the way. The study is presented as a communication campaign, involving multiple methodologies. The approach highlights how one method can build upon another and emphasizes the fact that, given the nature of methodology, no single study can give complete answers to our research questions.
Unique features of the text:
The tools gained herein will enable students to review, use, understand, and critique research, including the various aspects of appropriateness, sophistication and utility of research they encounter.
Model-Based Systems Engineering explains the fundamental theories behind model-based systems and the considerations involved in applying theory to the design of real systems. The book begins by presenting terms used in systems engineering and introducing the discrete system and its components. The remainder of the text explains topics such as the mathematical theory of system coupling, the homomorphic relationship between systems, the concept of system mode, the mathematical structure of T3SD system requirements, and the implications of that structure for T3SD system design. Appendices include a short bibliography, detailed definitions of all examples discussed in the text, a list of all notations used, and an index.
