Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials by G. V. Kozlov, Yu G. Yanovskii
2014 | ISBN: 1771880414 | English | 384 pages | PDF | 11 MB

Fractal Mechanics of Polymers: Chemistry and Physics of Complex Polymeric Materials
This new book explores the consideration of relationships that connect the structural and basic mechanical properties of polymeric mediums within the frameworks of fractal analysis with cluster model representations attraction. Incidentally, the choice of any structural model of medium or their combinations is defined by expediency and further usage convenience only. This book presents leading-edge research in this rapidly changing and evolving field.

The book presents descriptions of the main reactions of high-molecular substances within the frameworks of fractal analysis and irreversible aggregation models. Synergetics and percolation theory were also used. In spite of the enormous number of papers dealing with the influence of the medium on the rate of chemical reactions (including synthesis of polymers), no strict quantitative theory capable of "universal" application has been put forward up until now. It is now possible to describe the relationship between the reaction rate constants and the equilibrium constants with the nature of the medium in which the reactions take place by means of a single equation. This important book for the first time gives structural and physical grounds of polymers synthesis and curing, and the fractal analysis is used for this purpose.

This new book:

* Highlights some important areas of current interest in polymer products and chemical processes

* Focuses on topics with more advanced methods

* Emphasizes precise mathematical development and actual experimental details

* Analyzes theories to formulate and prove the physicochemical principles

* Provides an up-to-date and thorough exposition of the present state of the art of complex polymeric materials

Relativity, Gravitation and Cosmology: A Basic Introduction

FREEDownload : Relativity, Gravitation and Cosmology: A Basic Introduction

Relativity, Gravitation and Cosmology: A Basic Introduction By Ta-Pei Cheng
2009 | 355 Pages | ISBN: 0199573638 , 0199573646 | PDF | 6 MB

Relativity, Gravitation and Cosmology: A Basic Introduction
Einstein's general theory of relativity is introduced in this advanced undergraduate and beginning graduate level textbook. Topics include special relativity, in the formalism of Minkowski's four-dimensional space-time, the principle of equivalence, Riemannian geometry and tensor analysis, Einstein field equation, as well as many modern cosmological subjects, from primordial inflation and cosmic microwave anisotropy to the dark energy that propels an accelerating universe.
The author presents the subject with an emphasis on physical examples and simple applications without the full tensor apparatus. The reader first learns how to describe curved spacetime. At this mathematically more accessible level, the reader can already study the many interesting phenomena such as gravitational lensing, precession of Mercury's perihelion, black holes, and cosmology. The full tensor formulation is presented later, when the Einstein equation is solved for a few symmetric cases. Many modern topics in cosmology are discussed in this book: from inflation, cosmic microwave anisotropy to the "dark energy" that propels an accelerating universe.
Mathematical accessibility, together with the various pedagogical devices (e.g., worked-out solutions of chapter-end problems), make it practical for interested readers to use the book to study general relativity and cosmology on their own.

Precisely Predictable Dirac Observables
English | Physics, Mechanics, Mathematics | 18. October 2006 | ISBN-10: 1402051689 | 269 pages | pdf | 3 mb
This work presents a Clean Quantum Theory of the Electron, based on Dirac's equation.

Precisely Predictable Dirac Observables
"Clean" in the sense of a complete mathematical explanation of the well known paradoxes of Dirac's theory and a connection to classical theory. It discusses the existence of an accurate split between physical states belonging to the electron and to the positron as well as the fact that precisely predictable observables must preserve this split.

Capitalism: Its Origins and Evolution as a System of Governance

FREEDownload : Capitalism: Its Origins and Evolution as a System of Governance

Capitalism: Its Origins and Evolution as a System of Governance by Bruce R. Scott
English | ISBN 10: 146141878X | 2011 | PDF | 705 pages | 11,6 MB
Two systems of governance, capitalism and democracy, prevail in the world today. Operating simultaneously in partially distinct domains, these systems rely on indirect governance through regulated competition to coordinate actors; inevitably, these systems influence and transform each other.

Capitalism: Its Origins and Evolution as a System of Governance
This book rejects the simple equation of capitalism with markets in favor of a three-level system, a model which recognizes that markets are administered by regulators through institutions and governed by a political authority with the power to regulate behavior, punish transgressors, and redesign institutions. This system's emergence required the sovereign to relinquish some power in order to release the energies of economic actors. Rather than spreading through an unguided natural process like trade, capitalism emerged where competitive pressures forced political authorities to take risks in order to achieve increased revenues by permitting markets for land, labor, and capital.

Chaos and Structures in Nonlinear Plasmas

FREEDownload : Chaos and Structures in Nonlinear Plasmas

W. Horton, Y-H Ichikawa, "Chaos and Structures in Nonlinear Plasmas"
English | ISBN: 9810226365 | 1996 | 356 pages | Djvu | 4 MB

Chaos and Structures in Nonlinear Plasmas
This book develops the subject of nonlinear plasma physics from a general physics perspective. It begins with a description of nonlinear oscillations, the parametric instability, the pendulum, and the nonlinear island overlap criterion. The Kolomogorov-Arnold-Moser (KAM) theory is also analyzed. Laboratory visualizations of the KAM theory are presented for experiments in toroidal plasma confinement and rotating fluids. The subjects of transport in ExB flows and geostrophic flows are developed in parallel, stressing the generality of the Charney-Hasegawa-Mima equation. The dual nature of wave turbulence and vortex dynamics is developed for plasmas and geophysical flows. The presentation of the subject of nonlinear maps shows how maps are related to the nonlinear dynamics in plasma physics problems. Numerous space plasma and fusion physics examples are developed throughout the book. The final chapter deals with turbulence theory, renormalized mode coupling equations, and Kolomogorov-type spectra as modified for anisotropic plasmas.

Introduction to Space Dynamics

FREEDownload : Introduction to Space Dynamics

Introduction to Space Dynamics by William Tyrrell Thomson
1986 | ISBN: 0486651134 | English | 352 pages | EPUB | 24 MB

Introduction to Space Dynamics
Although this classic introduction to space-flight engineering was first published not long after Sputnik was launched, the fundamental principles it elucidates are as varied today as then. The problems to which these principles are applied have changed, and the widespread use of computers has accelerated problem-solving techniques, but this book is still a valuable basic text for advanced undergraduate and graduate students of aerospace engineering.
The first two chapters cover vector algebra and kinematics, including angular velocity vector, tangential and normal components, and the general case of space motion. The third chapter deals with the transformation of coordinates, with sections of Euler's angles, and the transformation of angular velocities.
A variety of interesting problems regarding the motion of satellites and other space vehicles is discussed in Chapter 4, which includes the two-body problem, orbital change due to impulsive thrust, long-range ballistic trajectories, and the effect of the Earth's oblateness. The fifth and sixth chapters describe gyrodynamics and the dynamics of gyroscopic instruments, covering such topics as the displacement of a rigid body, precession and nutation of the Earth's polar axis, oscillation of the gyrocompass, and inertial navigation.
Chapter 7 is an examination of space vehicle motion, with analyses of general equations in body conditions and their transformation to inertial coordinates, attitude drift of space vehicles, and variable mass. The eighth chapter discusses optimization of the performance of single-stage and multistage rockets. Chapter 9 deals with generalized theories of mechanics, including holonomic and non-holonomic systems, Lagrange's Equation for impulsive forces, and missile dynamics analysis.
Throughout this clear, comprehensive text, practice problems (with answers to many) aid the student in mastering analytic techniques, and numerous charts and diagrams reinforce each lesson. 1961 edition.
