Free Download Moving Acoustic Sources: Theory, Applications and Localization English | 2025 | ISBN: 9819608708 | 453 Pages | PDF EPUB (True) | 92 MB This book highlights the mathematical, physical, and technical properties of moving acoustic sources. Authors consider point sources and infinite or finite line sources moving along various curves in three-dimensional space. After studying the general theory of such sources, the frequency spectrum and the associated Doppler shift are derived explicitly for different trajectories. The sound radiation in half-spaces with a locally reacting and homogeneous ground is investigated in detail based on the knowledge of closed-form solutions for the stationary impulse response. An important field of application is the localization of moving sources. Among other approaches, an equivalent source method in the time domain is used to develop an effective source localisation method. Important practical applications are explored with these techniques, e.g. the detection of noise sources from trains and airplanes.  Free Download Mountain Path By Harriette Simpson Arnow 2012 | 276 Pages | ISBN: 1609173333 | PDF | 1 MB Masterfully wrought and keenly observed, Mountain Path draws on Harriette Simpson Arnow's experiences as a schoolteacher in downtrodden Pulaski County, Kentucky, deep in the heart of Appalachia, prior to WWII. Far from a quaint portrait of rural life, Arnow's novel documents hardships, poverty, illiteracy, and struggles. She also recognizes a fragile cultural richness, one characterized by "those who like open fires, hounds, children, human talk and song instead of TV and radio, the wisdom of the old who had seen all of life from birth to death," and which has since been eroded by the advent of highways and industry. In Mountain Path, Arnow exquisitely captures the voices, faces, and ways of a people she cared for deeply, and who evoked in her a deep respect and admiration.  Free Download Motivational Management By Alexander Hiam 2006 | 289 Pages | ISBN: 0814407382 | EPUB | 1 MB Hiam (the principal of a management consulting firm) offers advice on how business managers can encourage employee performance that relies on the tools and techniques he uses in his own consulting business. Chapters cover motivational communication, providing challenging opportunities, using feedback to motivate, transforming negative attitudes, appealing to individual motives, and using recognition and rewards. Annotation copyrighted by Book News, Inc., Portland, OR  Free Download Susan Steward, Linda Hargreaves, Charlotte Page, "Motivating Your Secondary Class" English | 2009 | pages: 208 | ISBN: 184787259X, 1847872603 | PDF | 2,3 mb Maurice Galton and his team have collected examples from various schools of what works in re-energizing demotivated pupils. This book presents practical advice and strategies for improving lower secondary school classrooms, ranging from reducing class size, to innovative induction programs emphasizing the development of core study skills, and developing effective procedures to train pupils to cooperate rather than confront each other during lessons.  Free Download Chaz Bowyer, Arthur Reed, Roland Beamont - Mosquito, Typhoon, Tempest At War Promotional Reprint Company | 1995 | ISBN: 1856482278 | English | 328 pages | PDF | 230.44 MB This book is the combination of two books, Mosquito at War & Typhoon and Tempest at War. Book is filled with photos of these war planes.  Free Download Morse Homology with Differential Graded Coefficients English | 2025 | ISBN: 3031880196 | 231 Pages | PDF (True) | 5 MB The key geometric objects underlying Morse homology are the moduli spaces of connecting gradient trajectories between critical points of a Morse function. The basic question in this context is the following: How much of the topology of the underlying manifold is visible using moduli spaces of connecting trajectories? The answer provided by "classical" Morse homology as developed over the last 35 years is that the moduli spaces of isolated connecting gradient trajectories recover the chain homotopy type of the singular chain complex.  Free Download More Than Words: How Talking Sharpens the Mind and Shapes Our World by Maryellen MacDonald, English | June 3rd, 2025 | ISBN: 0593545273 | 336 pages | True EPUB | 0.93 MB Humans are the only species that can transform internal ideas into talk, whether through speech, writing, or sign language. But why do we have this almost magical, special talent? It turns out that while talking allows us to share ideas and connect with one another, it isn't just for communication.  Free Download More Than Just a Dog: Understanding, loving and living with dogs. The indispensable guide for all dog lovers by Simon Wooler English | May 13, 2025 | ISBN: 0008707480 | 320 pages | PDF | 2.53 Mb Our ability to make meaningful connections with other animal species and their ability to return the favour is, perhaps, never more beautiful than the bond we have with dogs.  Free Download Moon Charleston & Savannah: Coastal Getaways, Southern Cuisine, History & Architecture English | 2025 | ASIN : B0DJP1522F | 521 Pages | True EPUB | 16 MB See the sights: Browse the museums on Savannah's historic River Street and take a carriage ride through Charleston's French Quarter. Check out the wares at the Old City Market, visit the First African Baptist Church, and learn about the area's important African American history  Free Download Monitoring Nuclear Weapons and Nuclear-Explosive Materials : An Assessment of Methods and Capabilities By National Research Council; Policy and Global Affairs; Committee on International Security and Arms Control 2005 | 266 Pages | ISBN: 0309095972 | EPUB | 1 MB In this study, CISAC tackles the technical dimensions of a longstanding controversy: To what extent could existing and plausibly attainable measures for transparency and monitoring make possible the verification of all nuclear weapons?strategic and nonstrategic, deployed and nondeployed?plus the nuclear-explosive components and materials that are their essential ingredients? The committee's assessment of the technical and organizational possibilities suggests a more optimistic conclusion than most of those concerned with these issues might have expected. |
