This book discusses statistical methods that are useful for treating problems in modern optics, and the application of these methods to solving a variety of such problems This book covers a variety of statistical problems in optics, including both theory and applications. The text covers the necessary background in statistics, statistical properties of light waves of various types, the theory of partial coherence and its applications, imaging with partially coherent light, atmospheric degradations of images, and noise limitations in the detection of light. New topics have been introduced in the second edition, including: Analysis of the Vander Pol oscillator model of laser light Coverage on coherence tomography and coherence multiplexing of fiber sensors An expansion of the chapter on imaging with partially coherent light, including several new examples An expanded section on speckle and its properties New sections on the cross-spectrum and bispectrum techniques for obtaining images free from atmospheric distortions A new section on imaging through atmospheric turbulence using coherent light The addition of the effects of “read noise” to the discussions of limitations encountered in detecting very weak optical signals A number of new problems and many new references have been added Statistical Optics, Second Edition is written for researchers and engineering students interested in optics, physicists and chemists, as well as graduate level courses in a University Engineering or Physics Department.
This book deals with applications in several areas of science and technology that make use of light which carries orbital angular momentum. In most practical scenarios, the angular momentum can be decomposed into two independent contributions: the spin angular momentum and the orbital angular momentum. The orbital contribution affords a fundamentally new degree of freedom, with fascinating and wide-spread applications. Unlike spin angular momentum, which is associated with the polarization of light, the orbital angular momentum arises as a consequence of the spatial distribution of the intensity and phase of an optical field, even down to the single photon limit. Researchers have begun to appreciate its implications for our understanding of the ways in which light and matter can interact, and its practical potential in different areas of science and technology.
Patanjali Yoga Sutras: Translation and Commentary in the Light of Vedanta Scripture is truly ground breaking, a unique perspective on these sutras that is both new and ancient.Aruna returns the gems of Patanjali from being limited within one of the six philosophical schools of medieval India to their universal fountainhead in the ancient scriptures of India. In the light of Vedanta scriptures they shine with a luster rarely seen since their inception over two thousand years ago.Connecting these sutras to hundreds of Veda and Vedanta mantras and the verses of the Bhagavad Gita, this modern translation and brilliant commentary succeeds in speaking directly to the listener's heart, not the sectarian head. Aruna lovingly treats these jewels as reflecting the freedom we all seek in life, not as historical artifacts of mystical curiosity.The sutras are in Sanskrit and transliteration, with English word-for-word and translation plus a rich, detailed commentary. Aruna's authoritative commentary brings in the connections of the sutras with the India sacred scriptures. This has never been attempted before in translation and reveals the universal application of these sutras to all Indians and to all students of all schools of yoga throughout the world.A must read for every student and teacher of yoga who yearns for rekindling the spiritual brilliance lying within the ethical and meditative practices of yoga.
With the land frozen under a coat of snow, the dogs sang of the pain of living. It was a song full of sadness - the same sadness their wild fathers had known, the same fear of the cold and dark. It woke up strong feelings in Buck, and as he sang with them, it took him back to the beginnings of life. This is the story of Buck, a domestic dog loyal to the ways of man, who is suddenly stolen and sold to work on the Yukon Trail. In this strange and hard new life, Buck's natural instincts slowly wake up to the call of the wild.
A Treatise Upon the Duties of Light Troopsby Colonel von EhwaldTwenty-Three Years Practice and Observations with Rifle Gunsby Ezekiel BakerAn iconic weapon and the soldiers who carried itThis remarkable and unique Leonaur edition comprises two vital accounts; one concerning the development of the military rifle in the British Army and the other a treatise on the formation and operational activities of the light troops who employed it and who made both the rifle and themselves famous. The treatise, translated from the original German, is the work of Colonel von Ehwald and is essentially a guide book for the conduct of the petit guerre-the skirmishing combat the riflemen and other light infantry knew. Ehwald also covers the activities of light cavalry. This is very far from being simply a military instruction manual because the author was no mere theorist. He fought during the American War of Independence in British pay with the mercenary Hessians and commanded a 'Jaeger' corps of light troops in the Danish Army. So the concepts he explains in his book have been elaborated by the inclusion of descriptions real battlefield incidents based on personal experience. Those interested in the activities of light troops in action will be introduced to the activities of Simcoe's Queen's Rangers and others. In its original edition this book was published using an archaic form of printed English with widespread use of ligatured characters and a form of the letter 'f'...
Published now in the Wisehouse Classics series, The Call of the Wild is a short adventure novel by Jack London published in 1903 and set in Yukon, Canada during the 1890s Klondike Gold Rush, when strong sled dogs were in high demand. The central character is a dog named Buck. The story opens at a ranch in the Santa Clara Valley of California when Buck is stolen from his home and sold into service as a sled dog in Alaska. He progressively reverts to a wild state in the harsh climate, where he is forced to fight to dominate other dogs. By the end, he sheds the veneer of civilization and relies on primordial instinct and learned experience to emerge as a leader in the wild.London spent almost a year in the Yukon collecting material for the book. The story was serialized in the Saturday Evening Post in the summer of 1903; it was published a month later in book form. The book's great popularity and success made a reputation for London. Much of its appeal derives from its simplicity as a tale of survival. As early as 1923, the story was adapted to film, and it has since seen several more cinematic adaptations.

When Arthur Clennam returns to England after many years abroad, he takes a kindly interest in Amy Dorrit, his mother's seamstress, and in the affairs of Amy's father, William Dorrit, a man of shabby grandeur, long imprisoned for debt in Marshalsea prison. As Arthur soon discovers, the dark shadow of the prison stretches far beyond its walls to affect the lives of many, from the kindly Mr Panks, the reluctant rent-collector of Bleeding Heart Yard, and the tipsily garrulous Flora Finching, to Merdle, an unscrupulous financier, and the bureaucratic Barnacles in the Circumlocution Office. A masterly evocation of the state and psychology of imprisonment, Little Dorrit is one of the supreme works of Dickens's maturity.
The first glimpse of the sea on Marine Drive filled my heart, if not my head. I turned away from the red shadow. I stopped thinking of that pyramid of killers, and Sanjay's improvidence. I stopped thinking about my own part in the madness. And I rode, with my friends, into the end of everything. Shantaram introduced millions of readers to a cast of unforgettable characters through Lin, an Australian fugitive, working as a passport forger for a branch of the Bombay mafia. In The Mountain Shadow, the long-awaited sequel, Lin must find his way in a Bombay run by a different generation of mafia dons, playing by a different set of rules. It has been two years since the events in Shantaram, and since Lin lost two people he had come to love: his father figure, Khaderbhai, and his soul mate, Karla, married to a handsome Indian media tycoon. Lin returns from a smuggling trip to a city that seems to have changed too much, too soon. Many of his old friends are long gone, the new mafia leadership has become entangled in increasingly violent and dangerous intrigues, and a fabled holy man challenges everything that Lin thought he'd learned about love and life. But Lin can't leave the Island City: Karla, and a fatal promise, won't let him go.
