  • Introduction to Control Systems

    • 2nd Edition
    • Volume 8
    • D K Anand
    • English
    This book is written for use as a text in an introductory course in control systems. The classical as well as the state space approach is included and integrated as much as possible. The first part of the book deals with analysis in the time domain. All the graphical techniques are presented in one chapter and the latter part of the book deals with some advanced material. It is intended that the student should already be familiar with Laplace transformations and have had an introductory course in circuit analysis or vibration theory. To provide the student with an understanding of correlation concepts in control theory, a new chapter dealing with stochastic inputs has been added. Also Appendix\A has been significantly expanded to cover the theory of Laplace transforms and z-transforms. The book includes worked examples and problems for solution and an extensive bibliography as a guide for further reading.

  • The Measurement of Mechanical Parameters in Machines

    • 1st Edition
    • N. P. Rayevskii
    • English
    The Measurement of Mechanical Parameters in Machines is a translation from the Russian version and presents methods used in the U.S.S.R. for measuring mechanical properties. This book discusses different indicators and accepted methods of measuring separate parameters. This text also explains the metrological characteristics of mechanical parameters that can be determined by applying the equations of motion, usually represented as equations of kinetic energy or as a Lagrangian equation. The electrical methods of measuring machines and recording results are noted, and the kinds of methods preferred because these are more suitable in investigating the kinematic and dynamic parameters of the machine are reviewed. This book also discusses the two groups that make up the electrical methods of measuring dimensions, which are composed of 1) capacitive, inductive and resistance pick-ups and 2) photoelectric and bolometric pick-ups. The author adds that in designing experimental research of a machine, determining the measurement of its principal parameters, such as displacements, linear velocities, acceleration, torque, and vibrations, is very important. This text also notes that some experimental problems may exist, such as those related to measurements of non-uniform rotation of shafts and the determination of effective inertia in a machinery. Automotive engineers, industrial mechanics, physicists, and professors and students in applied physics will find this book useful.

    • English
    An Introduction to Turbulence and Its Measurement is an introductory text on turbulence and its measurement. It combines the physics of turbulence with measurement techniques and covers topics ranging from measurable quantities and their physical significance to the analysis of fluctuating signals, temperature and concentration measurements, and the hot-wire anemometer. Examples of turbulent flows are presented. This book is comprised of eight chapters and begins with an overview of the physics of turbulence, paying particular attention to Newton's second law of motion, the Newtonian viscous fluid, and equations of motion. After a chapter devoted to measurable quantities, the discussion turns to some examples of turbulent flows, including turbulence behind a grid of bars, Couette flow, atmospheric and oceanic turbulence, and heat and mass transfer. The next chapter describes measurement techniques using hot wires, films, and thermistors, as well as Doppler-shift anemometers; glow-discharge or corona-discharge anemometers; pulsed-wire anemometer; and steady-flow techniques for fluctuation measurement. This monograph is intended for post-graduate students of aeronautics and fluid mechanics, but should also be readily understandable to those with a good general background in engineering fluid dynamics.

  • Commentaries in Plant Science

    Volume 2
    • 1st Edition
    • Harry Smith
    • English
    Commentaries in Plant Science, Volume 2 is a collection of papers that reviews developments in the pure and applied science of plants. One paper discusses the role of supercooling in the winter survival mechanism of and ecological distribution of many plant communities. Another paper evaluates the Cholodny-Went theory of shoot geotropism that there is strong evidence in auxin redistribution occurring in a rapid manner to cause geotropic curvature. The magnitude of auxin redistribution is too rare to cause differential growth. Some insect pests have specific nutritional requirements and well-developed mechanisms for selecting their plant host. One paper enumerates the benefits of using insect-resistant host plant varieties, such as the non-incurrence of extra costs, these are environmentally safe, and are compatible with most other methods of pest control. Another paper discusses the nature and possible genetic manipulation of a complex bacteria, the actinomycetes, as well as its role as antibiotic producer. Another paper examines the nature of seed storage proteins and of the cellular processes that are related in their synthesis and deposition especially in cereals and legume. This collection is suitable for botanists, genecologists, taxonomists, biologists, and investigators whose works involve cell membrane research.
