Book Description
This paper explains how viewpoint has misled us to believe that low and high pressure systems rotate in different directions in the Northern and Southern Hemispheres of Earth and other planetary, stellar and galactic bodies. The discussion will show that low pressure systems on Earth rotate in the same direction as the solid body, the planet, while high pressure systems rotate opposite to the planet’s direction of rotation, no matter what hemisphere you are in.

Book Description
Series in Cognition and Perception: Depth Perception Through Motion focuses on the processes, methodologies, and techniques involved in depth perception through motion, including optic array, rigid motions, illusions, and axis. The book first elaborates on the paradox of depth perception, illusions of motion in depth, and optic array. Discussions focus on rigid motions in three-dimensional space, perspective gradients, projection plane, stereokinetic effect, rotating trapezoid, and the windmill and fan illusions. The text then examines transformations leading to the perception of depth, slant perception, and perceived direction of rotary motion. Topics include shadow and computer projections, direct observation of rotating figures, a model of the perception of rotary motion, dynamic slant and static slant perception, translations along the Z axis, and rotations about the X or Y axis. The publication is intended for researchers and graduate students interested in depth perception in dynamic environments.

Book Description
Ever since the first observations of sunspots in the early seventeenth century, stellar rotation has been a major topic in astronomy and astrophysics. Jean-Louis Tassoul synthesizes a large number of theoretical investigations on rotating stars. Drawing upon his own research, Professor Tassoul also carefully critiques various competing ideas. In the first three chapters, the author provides a short historical sketch of stellar rotation, the main observational data on the Sun and other stars on which the subsequent theory is based, and the basic Newtonian hydrodynamics used to study rotating stars. Following a discussion of some general mechanical properties of stars in a state of permanent rotation, he reviews the main techniques for determining the structure of a rotating star and its stability with respect to infinitesimal disturbances. Since the actual distribution of angular momentum within stars is still unknown, Professor Tassoul considers various models of angular momentum as well as of meridional circulation. He devotes the rest of his study to the problems concerning various groups of stars and stages in stellar evolution. Originally published in 1979. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
This textbook on nuclear structure takes a unique approach to the topic, explaining nuclear structure by building on a few elementary physical ideas. Intricate topics such as shell model residual interactions, the Nilsson model, and the RPA analysis of collective vibrations are explained in a simple, intuitive way so that predictions can usually be made without calculations, essentially by inspection. Frequent data comparison shows the relevance of theoretical approaches. New to this edition are chapters on exotic nuclei and radioactive beams,and correlations of collective observables. Completely new discussions are given on isopin, the shell model, nature of collective vibrations, multi- phonon states, superdeformation, bandmixing, the geometric collective model, the fermei gas model, basic properties of simple nuclear potentials, the deuteron, etc.

Book Description
Renewable Energy Resources is a numerate and quantitative text covering the full range of renewable energy technologies and their implementation worldwide. Energy supplies from renewables (such as from biofuels, solar heat, photovoltaics, wind, hydro, wave, tidal, geothermal, and ocean-thermal) are essential components of every nation’s energy strategy, not least because of concerns for the local and global environment, for energy security and for sustainability. Thus in the years between the first and this third edition, most renewable energy technologies have grown from fledgling impact to significant importance because they make good sense, good policy and good business. This Third Edition is extensively updated in light of these developments, while maintaining the book’s emphasis on fundamentals, complemented by analysis of applications. Renewable energy helps secure national resources, mitigates pollution and climate change, and provides cost effective services. These benefits are analysed and illustrated with case studies and worked examples. The book recognises the importance of cost effectiveness and efficiency of end-use. Each chapter begins with fundamental scientific theory, and then considers applications, environmental impact and socio-economic aspects before concluding with Quick Questions for self-revision and Set Problems. The book includes Reviews of basic theory underlying renewable energy technologies, such as electrical power, fluid dynamics, heat transfer and solid-state physics. Common symbols and cross-referencing apply throughout; essential data are tabulated in appendices. An associated eResource provides supplementary material on particular topics, plus a solutions guide to Set Problems. Renewable Energy Resources supports multi-disciplinary master degrees in science and engineering, and specialist modules in first degrees. Practising scientists and engineers who have not had a comprehensive training in renewable energy will find it a useful introductory text and a reference book.

Book Description
On the Ulysses mission scientists gathered observations from the unexplored regions of the heliosphere. This book presents a highly readable and concise account of the results. The authors summarise our understanding of the area and provide the basis for understanding the more complex state of the heliosphere around solar maximum. The first chapter provides an overview of the region, introducing the heliosphere prior to the Ulysses mission, and mission objectives. Subsequent chapters discuss the areas of the heliosphere, large and small scale features, cosmic rays and energetic particles, and the observations of interstellar gas and cosmic dust.

Book Description
This Research Topic will focus on how the visual system recognizes objects regardless of variations in the viewpoint, illumination, retinal size, background, etc. Contributors are encouraged to submit articles describing novel results, models, viewpoints, perspectives and/or methodological innovations relevant to this topic. The issues we wish to cover include, but are not limited to, perceptual invariance under one or more of the following types of image variation: • Object shape • Task • Viewpoint (from the translation and rotation of the object relative to the viewer) • Illumination, shading, and shadows • Degree of occlusion • Retinal size • Color • Surface texture • Visual context, including background clutter and crowding • Object motion (including biological motion). Examples of questions that are particularly interesting in this context include, but are not limited to: • Empirical characterizations of properties of invariance: does invariance always exist? How wide is its range and how strong is the tolerance to viewing conditions within this range? • Invariance in naïve vs. experienced subjects: Is invariance built-in or learned? How can it be learned, under which conditions and how effectively? Is it learned incidentally, or are specific task and reward structures necessary for learning? How is generalizability and transfer of learning related to the generalizability/invariance of perception? • Invariance during inference: Are there conditions (e.g. fast presentation time or otherwise resource-constrained recognition) when invariance breaks? • What are some plausible computational or neural mechanisms by which invariance could be achieved?

Book Description
Everyone is familiar with the amazing performance of a modern smartphone, powered by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. The same amazing technology has also led to a deeper understanding of the nature of current flow and heat dissipation on an atomic scale which is of broad relevance to the general problems of non-equilibrium statistical mechanics that pervade many different fields.This book is based on a set of two online courses originally offered in 2012 on nanoHUB-U and more recently in 2015 on edX. In preparing the second edition the author decided to split it into parts A and B titled Basic Concepts and Quantum Transport respectively, along the lines of the two courses. A list of available video lectures corresponding to different sections of this volume is provided upfront.To make these lectures accessible to anyone in any branch of science or engineering, the author assume very little background beyond linear algebra and differential equations. However, the author will be discussing advanced concepts that should be of interest even to specialists, who are encouraged to look at his earlier books for additional technical details.
