Solitary Waves in Dispersive Complex Media Theory, Simulation, Applications


Free Download Solitary Waves in Dispersive Complex Media: Theory, Simulation, Applications by Vasily Yu. Belashov , Sergey V. Vladimirov
English | PDF | 2005 | 306 Pages | ISBN : 3540233768 | 3.1 MB
This book is devoted to one of the most interesting and rapidly developing areas of modern nonlinear physics and mathematics – the theoretical, analytical and advanced numerical, study of the structure and dynamics of one-dimensional as well as two- and three-dimensional solitons and nonlinear waves described by Korteweg-de Vries (KdV), Kadomtsev-Petviashvili (KP), nonlinear Schrödinger (NLS) and derivative NLS (DNLS) classes of equations. Special attention is paid to generalizations (relevant to various complex physical media) of these equations, accounting for higher-order dispersion corrections, influence of dissipation, instabilities, and stochastic fluctuations of the wave fields. The book addresses researchers working in the theory and numerical simulations of dispersive complex media in such fields as hydrodynamics, plasma physics, and aerodynamics. It will also be useful as a reference work for graduate students in physics and mathematics.

An Introduction to Hydrodynamics and Water Waves


Free Download An Introduction to Hydrodynamics and Water Waves by Bernard Méhauté
English | PDF | 1976 | 326 Pages | ISBN : 3642855695 | 55.6 MB
Hydrodynamics is the science which deals with the v motion of liquid in the macroscopic sense. It is essentially a field which is regarded as applied mathematics because it deals with the mathematical treatments of basic equations for a fluid continuum obtained on a purely Newtonian basis. It is also the foundation of hydraulics, which, as an art, has to compromise with the rigorous mathematical treatments because of nonlinear effects, inherent instability, turbulence, and the complexity of" boundary conditions" encountered in engineering practice. Therefore, this book can be considered as the text for a course in basic hydrodynamics, as well as for a course in the fundamentals of hydraulic and related engineering disciplines.

Nonlinear Waves and Inverse Scattering Transform

by Spencer Kuo

English | 2023 | ISBN: 1800614039 | 198 pages | True PDF | 7.91 MB
Nonlinear waves are essential phenomena in scientific and engineering disciplines. The features of nonlinear waves are usually described by solutions to nonlinear partial differential equations (NLPDEs). This book was prepared to familiarize students with nonlinear waves and methods of solving NLPDEs, which will enable them to expand their studies into related areas. The selection of topics and the focus given to each provide essential materials for a lecturer teaching a nonlinear wave course. Chapter 1 introduces "mode" types in nonlinear systems as well as Bäcklund transform, an indispensable technique to solve generic NLPDEs for stationary solutions. Chapters 2 and 3 are devoted to the derivation and solution characterization of three generic nonlinear equations: nonlinear Schrödinger equation, Korteweg-de Vries (KdV) equation, and Burgers equation. Chapter 4 is devoted to the inverse scattering transform (IST), addressing the initial value problems of a group of NLPDEs. In Chapter 5, derivations and proofs of the IST formulas are presented. Steps for applying IST to solve NLPDEs for solitary solutions are illustrated in Chapter 6.

Gravitational Waves How Einstein’s Spacetime Ripples Reveal the Secrets of the Universe


Free Download Gravitational Waves: How Einstein’s Spacetime Ripples Reveal the Secrets of the Universe by Brian Clegg, James Gillies, Dreamscape Media, LLC
English | 2022 | ISBN: N/A | ASIN: B093J486QK | MP3@64 kbps | 4 hours and 52 minutes | 134 Mb
On September 14, 2015, after 50 years of searching, gravitational waves were detected for the first time, and astronomy changed forever. Up until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays, and the rest. But gravitational waves – ripples in the fabric of space and time – are unrelenting, passing through barriers that stop light dead. At the two two-and-a-half-mile-long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015, they spotted the ripples produced by two black holes spiraling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected – and it promises far more for the future of astronomy.

Where the Waves Turn Back A Forty-Day Pilgrimage Along the California Coast [Audiobook]


Free Download Where the Waves Turn Back: A Forty-Day Pilgrimage Along the California Coast (Audiobook)
English | ASIN: B0BBSQ18KR | 2023 | 6 hours and 39 minutes | M4B@128 kbps | 372 MB
Author: Tyson Motsenbocker
Narrator: Tyson Motsenbocker

In this powerful memoir, following the death of his mother, Tyson Motsenbocker retraces the journey an 18th-century priest took in this harrowing story of one man’s pilgrimage of healing and finding beauty and hope in tragedy. After years on the road performing at sold-out venues, Tyson Motsenbocker returned home to the impending death of his 57-year-old hero and mother. He begged God to heal her, but she died anyway. When they buried her body, Tyson also buried the childhood version of his faith. Shortly before her death, however, Tyson became intrigued by the complicated legacy of Father Junipero Serra, the 18th-century Franciscan monk and canonized saint who dedicated his life to the idea that tragedy and suffering are portals to renewal. Father Serra built Missions up and down the California coast, spreading Christianity, as well as enabling and aiding in the oppression and colonization of the native Californians.

Dark Waves The Synthesizer and the Dystopian Sound of Britain (1977-80)


Free Download Dark Waves: The Synthesizer and the Dystopian Sound of Britain (1977-80) (Popular Musics Matter: Social, Political and Cultural Interventions) by Neil O’Connor
English | February 15, 2023 | ISBN: 1538165309 | True EPUB/PDF | 200 pages | 1.1/3.7 MB
Between 1977 and 1980, Britain was a country and culture in flux. The threat of nuclear war, mass unemployment, and strikes made it a particularly gloomy period historically. Within this, a growing number of electronic music acts were using technology and the synthesizer to soundtrack changing times.
