The Rosetta Stone of the Human Mind: Three Languages to Integrate Neurobiology and Psychology
by Vincenzo R. SanguinetiThe study of the brain-mind complex has been hampered by the dichotomy between objective biological neuroscience and subjective psychological science. This book presents a new theoretical model for how to "translate" between the two, using a third language: nonlinear physics and mathematics. It illustrates how the simultaneous use of these two approaches enriches the understanding of the neural and mental realms.

The Roswell Dig Diaries (Sci Fi Declassified #1)
by Thomas J. Carey William H. Doleman Donald R. SchmittIn July 1947, something crashed in the desert near Roswell, New Mexico. What that object was, as well as what happened in the days following the crash, has been hotly disputed ever since. Did the United States government cover up the existence of an extraterrestrial UFO? Were alien bodies recovered from the crash site? Or was it all nothing more than the failed launch of a weather balloon? The "Roswell Incident" remains one of the great unsolved mysteries of the twentieth century, and a source of enduring controversy. As part of the SCI FI Channel's ongoing mission to separate science fiction from science fact, the network sponsored an unprecedented, comprehensive archeological investigation of the crash site. Utilizing modern-day forensic tools, scientists from the University of New Mexico, in partnership with SCI FI, set out to uncover physical evidence to determine once and for all what really happened in the desert near Roswell. Only some of the team's discoveries were hinted at in SCI FI's highest-rated-ever documentary, The Roswell Crash: Startling New Evidence. Many have speculated about the true extent of what the dig team uncovered. Until now. The Roswell Dig Diaries presents to the public, for the very first time, the exclusive complete archeological report, including the final scientific conclusions of this landmark excavation and never-before-seen maps and photos of the crash site. This groundbreaking volume also takes you behind the scenes of the investigation with exclusive day-by-day personal journals and private company emails, written by everyone from the project leader, Dr. Bill Doleman, to Roswell Report authors Thomas J. Carey and Donald R. Schmitt, to SCI FI Channel executives, to the volunteer dig team members who helped make the investigation possible. Read the facts, sift through the evidence, and decide for yourself. Are we alone?
The Roswell Report: Case Closed
by United States ForceThroughout the twentieth century and into the twenty-first, the subject of unidentified flying objects (UFOs) has evoked strong opinions and emotions. For some, the belief in or study of UFOs (known as ufology) has taken on the dimensions of a religious quest. Others remain nonbelievers or at least skeptical of the existence of alien beings and elusive vehicles which never quite seem to manifest themselves. Regardless of one’s conviction, nowhere has the debate about UFOs been more spirited than over the events that unfolded near the small New Mexico city of Roswell in the summer of 1947. Numerous witnesses, including former military personnel and respectable members of the local community, have come forward with tales of humanoid beings, alien technologies, and government cover-ups that have caused even the most skeptical observers to pause and take notice.In July 1994, at the request of the Government Accounting Office, the U.S. Air Force completed a thousand-page report to explain the events that transpired in and near Roswell in the summer of 1947. That report sought to bring all the facts to light, declassify all the documents, and present the definitive truth to the public. The Roswell Report: Case Closed is the follow up to that report and contains additional materials and analysis intended to reach a complete, open, and final explanation of the events that occurred in the Southwest many years ago. While this explanation may not be as titillating as tales of unearthly craft and creatures, it is a fascinating story nonetheless.

Rotating Relativistic Stars
by John L. Friedman Nikolaos StergioulasThe masses of neutron stars are limited by an instability to gravitational collapse and an instability driven by gravitational waves limits their spin. Their oscillations are relevant to x-ray observations of accreting binaries and to gravitational wave observations of neutron stars formed during the coalescence of double neutron-star systems. This volume includes more than forty years of research to provide graduate students and researchers in astrophysics, gravitational physics and astronomy with the first self-contained treatment of the structure, stability and oscillations of rotating neutron stars. This monograph treats the equations of stellar equilibrium; key approximations, including slow rotation and perturbations of spherical and rotating stars; stability theory and its applications, from convective stability to the r-mode instability; and numerical methods for computing equilibrium configurations and the nonlinear evolution of their oscillations. The presentation of fundamental equations, results and applications is accessible to readers who do not need the detailed derivations.
Rotating Thermal Flows in Natural and Industrial Processes
by Marcello LappaRotating Thermal Flows in Natural and Industrial Processes provides the reader with a systematic description of the different types of thermal convection and flow instabilities in rotating systems, as present in materials, crystal growth, thermal engineering, meteorology, oceanography, geophysics and astrophysics. It expressly shows how the isomorphism between small and large scale phenomena becomes beneficial to the definition and ensuing development of an integrated comprehensive framework. This allows the reader to understand and assimilate the underlying, quintessential mechanisms without requiring familiarity with specific literature on the subject. Topics treated in the first part of the book include: * Thermogravitational convection in rotating fluids (from laminar to turbulent states);* Stably stratified and unstratified shear flows;* Barotropic and baroclinic instabilities;* Rossby waves and Centrifugally-driven convection;* Potential Vorticity, Quasi-Geostrophic Theory and related theorems;* The dynamics of interacting vortices, interacting waves and mixed (hybrid) vortex-wave states;* Geostrophic Turbulence and planetary patterns. The second part is entirely devoted to phenomena of practical interest, i.e. subjects relevant to the realms of industry and technology, among them: * Surface-tension-driven convection in rotating fluids;* Differential-rotation-driven (forced) flows;* Crystal Growth from the melt of oxide or semiconductor materials;* Directional solidification;* Rotating Machinery;* Flow control by Rotating magnetic fields;* Angular Vibrations and Rocking motions; Covering a truly prodigious range of scales, from atmospheric and oceanic processes and fluid motion in "other solar-system bodies", to convection in its myriad manifestations in a variety of applications of technological relevance, this unifying text is an ideal reference for physicists and engineers, as well as an important resource for advanced students taking courses on the physics of fluids, fluid mechanics, thermal, mechanical and materials engineering, environmental phenomena, meteorology and geophysics.

Rotorcraft Certification by Simulation and Analysis: An Introduction to the Principles and Practices (Springer Aerospace Technology)
by Mark White Gareth D. Padfield Stefan van ‘t Hoff Philipp Hofmeister Linghai Lu Giuseppe QuarantaThis open access book presents the steps necessary for the application of rotorcraft flight modelling and simulation and analysis in support of certification for compliance with EASA CS-27 and CS-29, SUBPART B—FLIGHT and other flight-related rules (e.g. CS-27/9, Appendix B, Airworthiness Criteria for Helicopter Instrument Flight). The material is presented in the form of a structured ‘Rotorcraft Certification by Simulation’ process, starting from the relevant paragraphs in the Certification Specifications, through a comprehensive description of the assembly of flight simulation requirements, informed by judgements on Influence, Predictability and Credibility, and on into the detailed building of the three major elements of the process; the Flight Simulation Model, the Flight Simulator, and the associated Flight Test Measurement System. The latter feeds both the flight model and simulator development with real-world test data to support validation and fidelity assessment. The book is intended to provide support to early adopters of simulation and analysis in the certification process, including those who have considerable experience and expertise in the use of Modelling and Simulation in support of design and development. It is acknowledged that there exists much good practice in the rotorcraft industry in this regard. However, what is presented herein is considered a significant step forward in the development of this practice, particularly in terms of the importance of a structured, requirements-based, process using adaptable-fidelity, descriptive and predictive simulation tools, and associated pre-certification flight testing, to reach the goal of a credible flight simulation.
Rotordynamics (Mechanical Engineering)
by Agnieszka MuszynskaAs the most important parts of rotating machinery, rotors are also the most prone to mechanical vibrations, which may lead to machine failure.

Mathematical modeling, in particular
Rotordynamics of Automotive Turbochargers
by Hung Nguyen-SchäferRotordynamics of automotive turbochargers is dealt with in this book encompassing the widely working field of small turbomachines under real operating conditions at the very high rotor speeds up to 300000 rpm. The broadly interdisciplinary field of turbocharger rotordynamics involves 1) Thermodynamics and Turbo-Matching of Turbochargers 2) Dynamics of Turbomachinery 3) Stability Analysis of Linear Rotordynamics with the Eigenvalue Theory 4) Stability Analysis of Nonlinear Rotordynamics with the Bifurcation Theory 5) Bearing Dynamics of the Oil Film using the Two-Phase Reynolds Equation 6) Computation of Nonlinear Responses of a Turbocharger Rotor 7) Aero and Vibroacoustics of Turbochargers 8) Shop and Trim Balancing at Two Planes of the Rotor 9) Tribology of the Bearing Surface Roughness 10) Design of Turbocharger Platforms using the Similarity Laws The rotor response of an automotive turbocharger at high rotor speeds is studied analytically, computationally, and experimentally. Due to the nonlinear characteristics of the oil-film bearings, some nonlinear responses of the rotor besides the harmonic response 1X, such as oil whirl, oil whip, and modulated frequencies occur in Waterfall diagram. Additionally, the influences of the surface roughness and oil characteristics on the rotor behavior, friction, and wear are discussed. This book is written by an industrial R&D expert with many years of experience in the automotive and turbocharger industries. The all-in-one book of turbochargers is intended for scientific and engineering researchers, practitioners working in the rotordynamics field of automotive turbochargers, and graduate students in applied physics and mechanical engineering.
Rotors: Stress Analysis and Design
by Vincenzo Vullo Francesco VivioStress and strain analysis of rotors subjected to surface and body loads, as well as to thermal loads deriving from temperature variation along the radius, constitutes a classic subject of machine design. Nevertheless attention is limited to rotor profiles for which governing equations are solvable in closed form. Furthermore very few actual engineering issues may relate to structures for which stress and strain analysis in the linear elastic field and, even more, under non-linear conditions (i.e. plastic or viscoelastic conditions) produces equations to be solved in closed form. Moreover, when a product is still in its design stage, an analytical formulation with closed-form solution is of course simpler and more versatile than numerical methods, and it allows to quickly define a general configuration, which may then be fine-tuned using such numerical methods. In this view, all subjects are based on analytical-methodological approach, and some new solutions in closed form are presented. The analytical formulation of problems is always carried out considering actual engineering applications. Moreover, in order to make the use of analytical models even more friendly at the product design stage, a function is introduced whereby it is possible to define a fourfold infinity of disk profiles, solid or annular, concave or convex, converging or diverging. Such subjects, even derived from scientific authors' contributions, are always aimed at designing rotors at the concept stage, i.e. in what precedes detailed design. Among the many contributions, a special mention is due for the following: linear elastic analysis of conical disks and disks with variable profile along its radius according to a power of a linear function, also subjected to thermal load and with variable density; analysis of a variable-profile disk subjected to centrifugal load beyond the material's yield point, introducing the completely general law expressed by a an n-grade polynomial; linear elastic analysis of hyperbolic disk, subjected to thermal load along its radius; linear elastic analysis of a variable-thickness disk according to a power of a linear function, subjected to angular acceleration; etc.

When dead plants and animals decay, they give life to a host of other creatures, and each one helps ecosystems thrive.Decomposition happens in the forest, the ocean—even in your stomach and between your teeth! From vultures and sharks to bacteria, maggots, mushrooms, and more, discover the dirty rotten truth about one of nature’s most fascinating processes.
Rough and Tumble: Aggression, Hunting, and Human Evolution
by Travis Rayne PickeringTravis Rayne Pickering argues that the advent of ambush hunting approximately two million years ago marked a milestone in human evolution, one that established the social dynamic that allowed our ancestors to expand their range and diet. He challenges the traditional link between aggression and human predation, however, claiming that while aggressive attack is a perfectly efficient way for our chimpanzee cousins to kill prey, it was a hopeless tactic for early human hunters, who--in comparison to their large, potentially dangerous prey--were small, weak, and slow-footed. Technology that evolved from wooden spears to stone-tipped spears and ultimately to the bow and arrow increased the distance between predator and prey and facilitated an emotional detachment that allowed hunters to stalk and kill large game. Based on studies of humans and of other primates, as well as on fossil and archaeological evidence, Rough and Tumble offers a new perspective on human evolution by decoupling ideas of aggression and predation to build a more realistic understanding of what it is to be human.

The Route Towards Global Sustainability: Challenges and Management Practices
by Pardeep Singh Yulia Milshina André Batalhão Sanjeev Sharma Marlia Mohd HanafiahThis volume discusses topics of global sustainability involving sustainability indicators, stakeholders' participation, and technological and strategic advances with the goal of "thinking locally to act globally". Scientists, academics, policymakers, and planners are currently focused on escalating global socioeconomic and ecological issues, such as rising inequality, adverse anthropogenic impacts on the environment, and deficiencies in natural resources. These variables are pushing the earth system's resistance capacity past its breaking point, with additional pressures incurred by a global pandemic. Therefore, this book looks to impart knowledge on participatory learning action research for human and environmental health and well-being. Sustainable development planning and management are needed in these pressing circumstances, and they necessitate an analytical interpretation of ongoing processes, current and future challenges, and an understanding of available tools and technologies. The main sections of the book focus on challenges and management practices for global sustainability, promoting educational values, smart initiatives in urban contexts, and integrating emerging sustainability dimensions in policies and legislation. The primary audience for the work is policy makers, urban planners, social scientists, economists, NGOs, and students, researchers, and educators engaged in environmental social science and sustainability management.
Routes to Absolute Instability in Porous Media
by Antonio BarlettaThis book addresses the concepts of unstable flow solutions, convective instability and absolute instability, with reference to simple (or toy) mathematical models, which are mathematically simple despite their purely abstract character. Within this paradigm, the book introduces the basic mathematical tools, Fourier transform, normal modes, wavepackets and their dynamics, before reviewing the fundamental ideas behind the mathematical modelling of fluid flow and heat transfer in porous media. The author goes on to discuss the fundamentals of the Rayleigh-Bénard instability and other thermal instabilities of convective flows in porous media, and then analyses various examples of transition from convective to absolute instability in detail, with an emphasis on the formulation, deduction of the dispersion relation and study of the numerical data regarding the threshold of absolute instability. The clear descriptions of the analytical and numerical methods needed to obtain these parametric threshold data enable readers to apply them in different or more general cases. This book is of interest to postgraduates and researchers in mechanical and thermal engineering, civil engineering, geophysics, applied mathematics, fluid mechanics, and energy technology.
