The Magic Volcano

The Magic Volcano

V K May

Opal Tree Press
2021
pokkari
On a plane from Australia to Papua New Guinea, Molly Marsh starts to explore the most unexplored country on Earth. By reading articles on her tablet, she learns PNG is one of the most biodiverse countries on the planet with over 200,000 species of plants and animals. The massive mountains and thick jungle isolate most of the villages from each other, resulting in over 800 languages and 1,000 cultures across the country.But Molly soon learns real life is even more exciting than what she reads in science journals. Join her as she teams up with Michael, the boy from next door, as they put their super smart science minds together to discover mysteries even the adults don't know about. Accompanied by a three-meter-long lizard named Ted, they discover something in the belly of a volcano. Intrigued, they climb down and find a bright turquoise lake amidst a remarkable collection of plants and animals that should not exist. Molly and Michael strive to understand the connections between these things before they tackle the most difficult question of all - what to do with this knowledge.

Embedded Random Matrix Ensembles in Quantum Physics

Embedded Random Matrix Ensembles in Quantum Physics

V.K.B. Kota

Springer International Publishing AG
2014
nidottu
Although used with increasing frequency in many branches of physics, random matrix ensembles are not always sufficiently specific to account for important features of the physical system at hand. One refinement which retains the basic stochastic approach but allows for such features consists in the use of embedded ensembles.The present text is an exhaustive introduction to and survey of this important field. Starting with an easy-to-read introduction to general random matrix theory, the text then develops the necessary concepts from the beginning, accompanying the reader to the frontiers of present-day research. With some notable exceptions, to date these ensembles have primarily been applied in nuclear spectroscopy. A characteristic example is the use of a random two-body interaction in the framework of the nuclear shell model. Yet, topics in atomic physics, mesoscopic physics, quantum information science and statistical mechanics of isolated finite quantum systems can also be addressed using these ensembles.This book addresses graduate students and researchers with an interest in applications of random matrix theory to the modeling of more complex physical systems and interactions, with applications such as statistical spectroscopy in mind.

Psychology of Technology

Psychology of Technology

V.K. Kool; Rita Agrawal

Springer International Publishing AG
2017
sidottu
This unique treatise expands on the philosophy of technology to argue for a psychology of technology based on the complex relationships between psychology, biology and technology, especially in the light of our relationships with our digital devices, our online lives, and our human experience. Drawing from disciplines ranging from philosophy and evolution to cognition and neuroscience, it examines myriad aspects of the brain’s creative development: the cognitive, sensory, and motor processes that enable technological progress and its resulting efficiencies and deficiencies along with our discomforts and pleasures. These experiences are key to behavioral and affective processes in technology, manifest in such diverse phenomena as multitasking, the shift in tech design from ergonomics to hedonomics, and the many types of online problem behaviors. Through these rich pages, readers can understand more deeply the history and future of human adjustment and adaptation in an environment intertwined with technology—and, with the ascendance of video games and virtual reality, new conceptions of the human self. Among the topics covered: Could we have remained a tech-devoid society?Technology, ergonomics and the non-executive functions of our body.New directions in brain-computer interface.From avatars and agents to virtual reality technology.On measuring affective responses to objects.Psychology, technology, ethics, and culture. A timely lens on a field that will grow in importance as it shapes our existence, Psychology of Technology will be read and discussed by not only psychologists, social scientists, and behavioral scientists, but also by technology designers and developers and those in biotechnology.

Basic models and concepts of machine dynamics and motion control are presented in the order of the principal steps of machine design. The machine is treated as a coupled dynamical system, including drive, mechanisms and controller, to reveal its behavior at different regimes through the interaction of its units under dynamic and processing loads. The main dynamic effects in machines are explained. The influence of component compliances on accuracy, stability and efficiency of the machines is analyzed. Methods for decreasing internal and external vibration activity of machines are described. The dynamic features of digital control are considered. Special attention is given to machines with intense dynamic behavior: resonant and hand-held percussion ones. Targeted to engineers as well as to lecturers and advanced students.

I don’t mind your thinking slowly, I mind your publishing faster than you think. Wolfgang Pauli (1900-1958) Technologies that use high frequency (ultrasonic) vibration to intensify processes are gaining wide recognition in scienti?c and industrial envir- ments. By superimposing high frequency vibration, the basic mechanical - haviour of many processesand materialsis seen to be transformed.This leads to the developmentof newmachines and processeswith advancedcharacter- tics. Despite the fact that ultrasonic technology has been employed for many years, there is no generalised understanding of ultrasonic machines and p- cesses.Theirdesignanddevelopmenthasmainlybeenachievedusingheuristic methods based on linear acoustical considerations. This book is intended to bridge the gap between the theory and prac- cal use of ultrasonic technology. It presents generalised foundations for the dynamics and control of ultrasonic processing systems. The main concept presented is to consider ultrasonic systems as special kinds of vibratory - chines that function by exploiting nonlinear dynamic processes. This assumes coupled considerations between the ultrasonic vibration’s in?uence on the processes, and the consequence of the transformed processing loads on the excitation and control of the working tools’ vibration. Analysis is conducted in a uni?ed manner and is based on structural and frequency methods that have become well established in engineering practice. These methods are adjusted by the authors for the application to nonlinear ultrasonic systems.

Theories of Fluids with Microstructure

Theories of Fluids with Microstructure

V.K. Stokes

Springer-Verlag Berlin and Heidelberg GmbH Co. K
2011
nidottu
This book provides an introduction to theories of fluids with microstruc­ ture, a subject that is still evolving, and information on which is mainly available in technical journals. Several approaches to such theories, employ­ ing different levels of mathematics, are now available. This book presents the subject in a connected manner, using a common notation and a uniform level of mathematics. The only prerequisite for understanding this material is an exposure to fluid mechanics using Cartesian tensors. This introductory book developed from a course of semester-length lec­ tures that were first given in the Department of Chemical Engineering at the University of Delaware and subsequently were given in the Department of Mechanical Engineering at the Indian Institute of Technology, Kanpur. The encouragement of Professor A. B. Metzner and the warm hospitality of the Department of Chemical Engineering, University of Delaware, where the first set of notes for this book were prepared (1970-71), are acknowledged with deep appreciation. Two friends and colleagues, Dr. Raminder Singh and Dr. Thomas F. Balsa, made helpful suggestions for the improvement of this manuscript. The financial support provided by the Education Development Centre of the Indian Institute of Technology, Kanpur, for the preparation of the manuscript is gratefully acknowledged.
