Hydraulic Control of Machine Tools presents the wide range of application of hydraulic drives. This book discusses the methods, principles of design of hydraulic systems, and their equipment. Organized into 11 chapters, this book begins with an overview of hydraulic drives that utilize mainly the kinetic energy of the flow. This text then examines the tasks of hydraulic fluids not only to induce and receive motion but also to be a reliable lubricant for the hydraulic mechanisms. Other chapters consider the various points to be considered in the calculation of hydraulic systems. This book discusses as well the various types of hydraulic circuits that are used in machine tools. The final chapter deals with several examples of hydraulic calculations, including calculations of the axial force exerted by the flow on a valve. This book is a valuable resource for hydraulic specialists and mechanical engineers.

Theory of Jets in Ideal Fluids focuses on the use of hydrodynamics in the theory of jets in ideal fluids. The publication first offers information on the introduction to the theory of plane and steady jet flows and flow from a vessel. Discussions focus on flow from a rectangular vessel with an orifice at a corner; vessel with a funnel-shaped bottom and Borda's nozzle; flow from the opening between two flat plates; and Kirchhoff's method. The text then examines infinite flow past a polygonal obstacle, flow around curvilinear obstacles, and flow around a body at small cavitation number. Topics include cavitating flow around a circular cylinder; cavitating flow around a thin profile at an arbitrary angle of attack; cavitating flow around a flat plate; Villat's integro-differential equation and the existence and uniqueness of the solution; and flow past a plate with the separation from its upper surface. The book takes a look at the flow of a heavy fluid and the effects of surface tension, axisymmetric flow, jet flow of compressible fluid, and unsteady flows. The publication is a dependable reference for hydrodynamicists wanting to explore the theory of jets in ideal fluids.

A Course of Mathematics for Engineers and Scientists offers a mathematics course for undergraduate students reading science and engineering at British and Commonwealth Universities and colleges. The aim of this volume is to generalize and develop the ideas and methods of earlier volumes so that the student can appreciate and use the mathematical methods required in the more advanced parts of physics and engineering. This book begins with elementary ideas of vector algebra which are generalized and developed in two ways. The first is an account of vector analysis and the differential and integral operations and theorems concerning vectors. These ideas find their first generalization in tensor analysis and the transformation of coordinates, including orthogonal curvilinear coordinates. The second development is to matrices, where the properties of arrays of elements, linear equations, and quadratic forms are shown to be the generalizations of elementary algebra and, using 'vector space', of familiar geometrical ideas to n dimensions. The solution of differential equations by series provides a general method for the solution of ordinary and some partial differential equations. A discussion of the properties of the solutions in the light of the Sturm-Liouville theory introduces the conceptions of eigenvalues and orthogonal functions, forming a link with matrices. A chapter on the special functions gives some of the better known properties of Bessel, Legendre, Laguerre, and Hermite functions, which commonly occur in the solution of boundary and initial value problems.

Mechanisms for the Generation of Plane Curves focuses on the possibility of generating plane curves through kinematic linkages. The book first offers information on the basic theory of the generation of curves by mechanisms with higher pairs of the fourth class and fundamentals of the theory of the generation of curves using mechanisms with lower pairs of class V. Discussions focus on generation of curves by centrode and trajectory pairs; generation of curves with five-link and six-link kinematic chains; basic theorem for the mechanical generation of algebraic curves; and use of the properties of individual forms of transformation mechanisms. The text then examines mechanical generation of straight lines and circles and mechanical generation of ellipses, hyperbolas, and parabolas. The publication ponders on the mechanical generation of third degree curves and mechanical generation of curves of the fourth degree. Topics include mechanisms for generating curves of the focal type; mechanisms for generating special forms of curves; and mechanisms for the generation of the conchoids of the straight line and the circle. The text is a dependable reference for readers interested in the mechanisms involved in plane curves.

Discussions focus on theoretical principles, frequency characteristics of impulse functions, determination of the value of the system response to an impulse disturbance at instants of time between impulses, and derivatives and integrals of impulse functions. The text ponders on the stability of circuits with variable parameters and the stability of periodic modes of operation in non-linear circuits, including the approximate method for investigating the stability of periodic modes of operation; remarks on the investigation of the stability of circuits with feedback containing parameters varying periodically (or exponentially); and analysis of the stability of pulse circuits with feedback.

Excitation Control is a translation from the Russian and deals with the principles of control related to the use of excitation as a controlling or regulating effect. This book discusses the research made on different ways to control various objects through automatic regulation, and the laws or principles behind any of these developments. The text focuses on the controls associated with the principle of excitation (invariance) regulation, as well as, the relevant methods and procedures of measurement, transmission or conversion of information in control and regulation systems. The book describes the principal types of automatic control systems and measuring devices that operate on excitation. The author also explains the elements of the theory of automatic control systems that operate on excitation such as the conditions of absolute invariance and the realizability of these conditions. The book then presents examples of calculations concerning combined tracing systems and automatic control systems. This book can prove useful for mathematicians, students, and professor advanced mathematics or physics. Engineers or technicians interested in automatic control and regulation will find this book valuable.
