Computational Techniques of Rotor Dynamics with the Finite Element Method
Rotor dynamics is both a classical and a modern branch of engineering science. The rotation of rigid bodies, mainly those with regular shapes such as cylinders and shafts, has been well understood for more than a century. However, analyzing the rotational behavior of flexible bodies, especially those with irregular shapes like propellers and blades, requires more modern tools such as finite elements, hence the title and focus of this book.In the dozen years since the original publication, this book was used in teaching engineering students at universities and in consulting in the industry. During those activities, several topics were deemed to require further explanations. Students requested a deeper finite element technology foundation in certain places to make the book self-contained in that regard also. Some desired more details about the computational and numerical solutions. These requests are answered in new sections of this edition. Practicing engineers asked for a detailed industrial application case study and such was added in a new chapter dealing with wind turbines.This book is composed of two parts, the first focusing on the theoretical foundation of rotor dynamics and the second focusing on the engineering analysis of industrial structures. The theoretical foundation is built on physics, calculus, and finite element technology chapters. Computational and numerical techniques provide free vibration and response analyses solutions. The industrial engineering analysis part contains chapters analyzing jet-engine turbine wheels, aircraft propellers, and wind turbine blades. This book concludes with a new industrial case study based on a recent modern wind turbine development project.
Thermal Metamaterials
This book gives a comprehensive review on thermal metamaterials, an emerging type of artificial structures designed for the control of heat transfer. To date, many exciting findings have been made in this field, including some novel understandings about the heat transfer processes (reciprocity, symmetry, topological properties, etc.), as well as promising new possibilities to control heat (cloaking, rectification, collection, etc.). The text is organized into three segments: steady-state, time-harmonic, and transient heat transfer. In Part I, the transformation theory and effective medium method are introduced with their applications on the manipulation of steady-state heat transfer, covering early studies in this field. In Part II, the recently developed thermal scattering theory and temporal modulation method are discussed in the context of controlling time-harmonic heat transfer. In Part III, the effective Hamiltonian method is presented to study the decaying thermal modes in transient heat transfer. We include detailed derivations and examples for each theory or method. The book ends with an outlook chapter on open problems and potential possibilities in this promising field.

Excitons and Cooper Pairs
This book bridges a gap between two major communities of Condensed Matter Physics, Semiconductors and Superconductors, that have thrived independently. Using an original perspective that the key particles of these materials, excitons and Cooper pairs, are composite bosons, the authors raise fundamental questions of current interest: how does the Pauli exclusion principle wield its power on the fermionic components of bosonic particles at a microscopic level and how this affects their macroscopic physics? What can we learn from Wannier and Frenkel excitons and from Cooper pairs that helps us understand "bosonic condensation" of composite bosons and its difference from Bose-Einstein condensation of elementary bosons? The authors begin with a solid mathematical and physical foundation to derive excitons and Cooper pairs. They further introduce Shiva diagrams as a graphic support to grasp the many-body physics induced by fermion exchange in the absence of fermion-fermion interaction - a novel mechanism not visualized by standard Feynman diagrams. Advanced undergraduate or graduate students in physics with no specific background will benefit from this book. The developed concepts and formalism should also be useful for current research on ultracold atomic gases and exciton-polaritons, and quantum information.
From Galileo to Einstein
Our current lives are a result of scientific evolution to which many geniuses in science have contributed. This book describes the lives of great scientists from Galileo to Einstein who made remarkable discoveries in science. By focusing on their stories, the reader will understand that the common trait shared by them in their scientific journey was a genuine enthusiasm to scholarship.The Progress of science is surveyed as follows: Galileo called the father of modern science, expressed natural phenomena with quantitatively measurable quantities, such as weight and length for the first time. Kepler discovered Kepler's laws that explained the movement of celestial bodies. It was however not understood why celestial bodies moved according to Kepler's laws. This problem was elucidated by Newton founding Newtonian mechanics. Electromagnetic phenomena experimentally discovered by Faraday, were theoretically unified by Maxwell who founded electromagnetic theory, constituting the two greatest theories in classical physics together with Newtonian mechanics until the end of nineteenth century.At the end of nineteenth century, two experimental results could not explained by classical physics. The one was the result on the black body radiation. For elucidating the result, Planck in 1900 derived Planck's formula, discovering the concept of "quantum." The other was Michelson-Morley experiment's result supporting relativity principle. For elucidating the result, Einstein developed relativistic theory, constituting the two greatest theories of twentieth century together with quantum mechanics.The readers can understand the progress in physics from classical physics to modern physics, impressed by the lives of geniuses with a genuine enthusiasm to scholarship.
Digital Processing of Acoustic Signals
This book particularly presents basic and novel theories with practical examples of the two main topics: of Digital Processing of Acoustic Signals, such as: Speech and Heart Sounds. Namely: - Digital Room Acoustics Equalization, because in many sound reproduction systems the degradation quality of the speech signal is mainly caused by the room effect, and- Automatic Heart Sounds Segmentation, as it is an essential phase before objective analysis and diagnosis.Homomorphic standard method and its modified version for equalizing room acoustics effects on the speech signal are presented. An alternative approach to the Balanced Model Truncation method (standard method) is proposed. This when compared to the standard method allows reducing substantially the equalization filter order.A novel automatic heart sounds segmentation method is proposed and applied to professional regular rhythms heart sounds of adult patients.

Classical Continuum Mechanics
This book provides physical and mathematical foundation as well as complete derivation of the mathematical descriptions and constitutive theories for deformation of solid and fluent continua, both compressible and incompressible with clear distinction between Lagrangian and Eulerian descriptions as well as co- and contra-variant bases. Definitions of co- and contra-variant tensors and tensor calculus are introduced using curvilinear frame and then specialized for Cartesian frame. Both Galilean and non-Galilean coordinate transformations are presented and used in establishing objective tensors and objective rates. Convected time derivatives are derived using the conventional approach as well as non-Galilean transformation and their significance is illustrated in finite deformation of solid continua as well as in the case of fluent continua.Constitutive theories are derived using entropy inequality and representation theorem. Decomposition of total deformation for solid and fluent continua into volumetric and distortional deformation is essential in providing a sound, general and rigorous framework for deriving constitutive theories. Energy methods and the principle of virtual work are demonstrated to be a small isolated subset of the calculus of variations. Differential form of the mathematical models and calculus of variations preclude energy methods and the principle of virtual work. The material in this book is developed from fundamental concepts at very basic level with gradual progression to advanced topics.This book contains core scientific knowledge associated with mathematical concepts and theories for deforming continuous matter to prepare graduate students for fundamental and basic research in engineering and sciences. The book presents detailed and consistent derivations with clarity and is ideal for self-study.

Structure and Interpretation of Classical Mechanics, second edition
The new edition of a classic text that concentrates on developing general methods for studying the behavior of classical systems, with extensive use of computation. We now know that there is much more to classical mechanics than previously suspected. Derivations of the equations of motion, the focus of traditional presentations of mechanics, are just the beginning. This innovative textbook, now in its second edition, concentrates on developing general methods for studying the behavior of classical systems, whether or not they have a symbolic solution. It focuses on the phenomenon of motion and makes extensive use of computer simulation in its explorations of the topic. It weaves recent discoveries in nonlinear dynamics throughout the text, rather than presenting them as an afterthought. Explorations of phenomena such as the transition to chaos, nonlinear resonances, and resonance overlap to help the student develop appropriate analytic tools for understanding. The book uses computation to constrain notation, to capture and formalize methods, and for simulation and symbolic analysis. The requirement that the computer be able to interpret any expression provides the student with strict and immediate feedback about whether an expression is correctly formulated. This second edition has been updated throughout, with revisions that reflect insights gained by the authors from using the text every year at MIT. In addition, because of substantial software improvements, this edition provides algebraic proofs of more generality than those in the previous edition; this improvement permeates the new edition.
Phase-Transformation-Stress Interactions in Composite Materials III
This book presents original mathematical models of phase-transformation stress interactions in composite materials, which result from the iteration method, along with mathematical models of phase-transformation induced micro-/macro-strengthening and intercrystalline or transcrystalline crack formation. The mathematical determination results from mechanics of an isotropic elastic continuum. The materials consist of an isotropic matrix with isotropic ellipsoidal inclusions. These stresses are a consequence of the difference between dimensions of crystalline lattices, which are mutually transformed during the phase-transformation process in the inclusion and/or the matrix. The mathematical models include microstructural parameters of a real matrix-inclusion composite, and are applicable to composites with ellipsoidal inclusions of different morphology (e.g., dual-phase steel, martensitic steel). In case of a real matrix-inclusion composite, such numerical values of the microstructural parameters can be determined, which result in maximum values of the micro- and macro-strengthening, and which define limit states with respect to the crack formation in the matrix or the inclusion.

These stresses are a consequence of the difference between dimensions of crystalline lattices, which are mutually transformed during the phase-transformation process in the inclusions, the envelope or the matrix. The mathematical determination results from mechanics of an isotropic elastic continuum, and results in different mathematical solutions. Due to these different mathematical solutions, the principle of minimum elastic energy is considered. The mathematical models for the three-component materials are applicable to those for the phase-transformation-stress induced micro-/macro-strengthening and crack formation in the two-component materials, which are determined in the first volume.
Thermal-Stress-Field Interactions in Composite Materials II
This book presents original mathematical models of thermal-stress-field interactions in composite materials with three components. In contrast to mathematical models for two-component materials, which are determined in the first volume, the three-component materials consist of an isotropic matrix and isotropic ellipsoidal inclusions with an isotropic ellipsoidal envelope. These stresses are a consequence of different thermal expansion coefficients of the material components. The mathematical determination results from mechanics of an isotropic elastic continuum, and results in different mathematical solutions. Due to these different mathematical solutions, the principle of minimum elastic energy is considered. The mathematical models for the three-component materials are applicable to those for the thermal-stress induced micro-/macrostrengthening and crack formation in the two-component materials, which are determined in the first volume.

An Introduction to Quantum Mechanics
The core content of even the most intricate intellectual edifices is often a simple fact or idea. So is it with quantum mechanics; the entire mathematical fabric of the formal description of quantum mechanics stems essentially from the fact that quantum probabilities interfere (i.e., from the superposition principle). This book is dedicated to substantiating this claim. In the process, the book tries to demonstrate how the factual content of quantum mechanics can be transcribed in the formal language of vector spaces and linear transformations by disentangling the empirical content from the usual formal description. More importantly, it tries to bring out what this transcription achieves.The book uses a pedagogic strategy which reverse engineers the postulates of quantum mechanics to device a schematic outline of the empirical content of quantum mechanics from which the postulates are then reconstructed step by step. This strategy is adopted to avoid the disconcerting details of actual experiments (however simplified) to spare the beginner of issues that lurk in the fragile foundations of the subject.In the Copenhagen interpretation of quantum mechanics, the key idea is measurement. But "measurement" carries an entirely different meaning from the connotation that the term carries elsewhere in physics. This book strives to underline this as strongly as possible.The book is intended as an undergraduate text for a first course in quantum mechanics. Since the book is self contained, it may also be used by enthusiastic outsiders interested to get a glimpse of the core content of the subject.Features: Demonstrates why linear algebra is the appropriate mathematical language for quantum mechanics. Uses a reconstructive approach to motivate the postulates of quantum mechanics. Builds the vocabulary of quantum mechanics by showing how the entire body of its conceptual ingredients can be constructed from the single notion of quantum measurement.

One-Matter Nature Science
The (nature) science discovered by Copernicus and Galileo during the 16th and 17th Centuries has a definition of using a specific scientific method, the experimental method, to make scientific discoveries to ensure that science has only one correct answer and to interpret findings leading to the development of mechanical physics. The definition of science must be obeyed to be correct science. Yet, the theories of modern physics disobey the definition of science by using the mathematic-derivation method to offer a second scientific answer, which is wrong scientifically. Einstein's scientific revolution has misled our scientific community to develop and to teach modern physics as the mainstream of thought of today's science. A scientific revolution is needed to remove modern physics from science and to bring our scientific community including our government back to original science.This 2nd edition book adds my new theories of light and Galaxy to further prove that the original science or the one-matter nature science is the only and entire correct science.
