Braced Frameworks
An Introduction to the Theory of Structures
2nd Edition
E. W. Parkes
B. G. Neal
English
Structures and Solid Body Mechanics Series: Braced Frameworks: An Introduction to the Theory of Structures, Second Edition focuses on the principles, methodologies, and approaches employed in the application of braced frameworks in engineering. The publication first elaborates on basic concepts and statically determinate trusses. Discussions focus on properties of symmetrical structures, displacements of trusses, superposition of loads on a truss, conditions for statical determinacy, environment and deformation, braced and non-braced frames, equilibrium, and compatibility. The manuscript then examines redundant trusses and secondary stresses and the failure of braced frameworks. Topics cover failure of braced frameworks, solution by slope-deflection equations, relaxation methods, direct comparison of lengths, number and choice of redundancies, and energy methods. The book tackles minimum weight frameworks and secondary stresses and the failure of braced frameworks, as well as the symmetrical three-force system, form of the optimum structure, and solution by moment distribution. The publication is a vital reference for engineers and researchers wanting to explore braced frameworks.

Structural Concrete
The Commonwealth and International Library: Structures and Solid Body Mechanics Division
1st Edition
J. D. Davies
B. G. Neal
English
Structural Concrete examines the behavior of reinforced and prestressed concrete structures under working load and ultimate load conditions. This eight-chapter text deals first with the analysis of concrete structures as a particular branch of structural mechanics. Other chapters explore the empirical methods and the practical design and detailing procedures. Considerable chapters describe the mechanical behavior of structural concrete, with a particular emphasis on the elastic behavior. The final chapters examine the behavior of continuous beams, frames, and slabs. These chapters also look into the models for structural concrete. This book is intended primarily to undergraduate civil engineering students.
Matrix Analysis of Electrical Machinery
2nd Edition
N. N. Hancock
English
Matrix Analysis of Electrical Machinery, Second Edition focuses on the systematic matrix analysis of the performance of electrical machinery, including circuits, current transformation, and matrix techniques. The manuscript first covers the elements of matrix algebra, application of matrix algebra to static electrical networks, and transformers. Topics include three-winding transformers, transformation of voltage and impedance for invariant power with a given current transformation, linear transformation in electrical circuit analysis, differentiation and integration of a matrix, linear transformation, matrix representation of simultaneous equations, and alternative methods of inversion. The book then ponders on matrix equations of the basic rotating machines, torque expressions, linear transformations in circuits and machines, and application of matrix techniques to routine performance calculations. Discussions focus on phasor diagrams and equivalent circuits, analysis of three-phase machines, physical interpretation of various sets of axes, equivalence of three-phase and two-phase systems, energy stored in the magnetic fields, and matrix equations of slip-ring and squirrel-cage machines. The text takes a look at miscellaneous machine problems, small oscillations, and steady-state performance of polyphase machines. The publication is a fine reference for researchers wanting to explore the matrix analysis of electrical machinery.
Liberal Studies
An Outline Course
1st Edition
N. C. Dexter + 1 more
C. V. James + 2 more
English
Liberal Studies: An Outline Course, Volume One serves as a starting-point for provoking serious and informed discussion of liberal studies. This book basically compiles a series of essays or articles on selected topics of general interest, followed in most cases by a list of quotations taken from various authors. Such topics include education, use of studying Latin or Greek, and pacifism. This publication also pays attention to things of a less specific nature, but things that are interesting and important just the same and things that will be profitable if considered. Other topics include history and progress, law and justice, patriotism and rise of nationalism, science and Christianity, and truth and nature of reality. This volume is recommended for students taking liberal studies and teachers teaching the subject.
Electrical Correcting Elements in Automatic Control and Regulation Circuits
1st Edition
G. K. Krug + 1 more
English
Electrical Correcting Elements in Automatic Control and Regulation Circuits presents the problems of matching some regulator to the device which is to be regulated. This book describes a large number of electrical correcting and stabilizing devices. Organized into two chapters, this book begins with an overview of the theory of automatic regulation. This text then discusses problems which have to do with the introduction of correcting and stabilizing devices into systems of automatic regulation and control. This book provides as well practical recommendations for the application in automatic control systems. The final chapter deals with the components and circuits of correcting devices. This book is a valuable resource for engineers who work in the field of the design and application of automatic regulating and controlling systems.
Advanced Calculus and Vector Field Theory
1st Edition
Kathleen M. Urwin
English
THIS book falls naturally into two parts. In Chapters 1-5 the basic ideas and techniques of partial differentiation, and of line, multiple and surface integrals are discussed. Chapters 6 and 7 give the elements of vector field theory, taking the integral definitions of the divergence and curl of a vector field as their starting points; the last chapter surveys very briefly some of the immediate applications of vector field theory to five branches of applied mathematics. Throughout I have given numerous worked examples. In these I have paid particular attention to those points which in my own experience I have found to give most difficulty to students. In the text I have denoted spherical polar coordinates by (/-, 0, ψ)9 and cylindrical polar coordinates by (p, ψ, ζ), so that ψ measures the same angle in both systems. Since there is no one standard notation for these systems, the reader will meet different notations in the course of his reading, and in quoting examination questions in the exercises I have kept to the notation of the originals. The Exercises at the end of each section are intended to give practice in the basic techniques just discussed. The Miscellaneous Exercises are more varied, and contain many examination questions.
Complex Variables
1st Edition
H. R. Chillingworth
C. Plumpton
English
Complex Variables focuses on the principles, characteristics, and functions of complex variables, as well as infinite series, complex numbers, and convergence and divergence. The book first examines complex numbers and the sequences and limits of point sets in the complex plane. Discussions focus on non-decreasing real sequences, boundedness of convergent sequences, boundary points, closed sets, bounded and unbounded sets in the complex plane, complex conjugates, complex numbers as an extension of the real number field, scalar multiplication, modulus, and number pairs. The manuscript then takes a look at the tests for convergence of infinite series, functions of a complex variable, and elementary functions. Concerns cover repeated differentiation of an infinite series, differentiability of power series, hyperbolic functions, link between the exponential and trigonometric functions, orthogonal families of curves, differentiability, testing for convergence or divergence, and series with negative or complex terms. The text examines miscellaneous theorems, contour integration, zeros and singularities, and integration, including order of magnitude of a function, infinite integrals involving trigonometric functions, and sum-limit and anti-differentiation... The publication is highly recommended for students and teachers wanting to explore complex variables.

Discussions focus on organizational and curricular changes, results of economic pressures on schools, ideological pressures on schools, education by synthesis and constructive comparison, changed dimensions of education, conditional relevance of schools, enlargement of educational concepts, and changes in occupational structure. The text then tackles the measurement of human abilities and their cultivation, status, role, and future of teachers, media and the teacher, and teachers, research, and curricular development.
