This book was released on 2004-09-01 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to assess the benefit of assimilating satellite altimeter data into the Modular Ocean Data Assimilation System (MODAS) . To accomplish this, two different MODAS fields were used by the Weapon Acoustic Preset Program (WAPP) to determine suggested presets for a Mk 48 variant torpedo. The MODAS fields differ in that one uses altimeter data assimilated from three satellites while the other uses no altimeter data. The metric used to compare the two sets of outputs is the relative difference in acoustic coverage are generated by WAPP. Output presets are created for five different scenarios, two Anti-Surface Warfare scenarios and three Anti-Submarine Warfare scenarios, in each of three regions: the East China Sea, the Sea of Japan, and an area south of Japan that includes the Kuroshio current. Analysis of the output reveals that, in some situations, WAPP output is very sensitive to the inclusion of the altimeter data because of the resulting differences in the subsurface predictions. The change in weapon presets could be so much that the effectiveness of the weapon might be affected.
Book Synopsis Value Aided Satellite Altimetry Data for Weapon Presets by : Michael D. Perry
Download or read book Value Aided Satellite Altimetry Data for Weapon Presets written by Michael D. Perry and published by . This book was released on 2003-06-01 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to determine the effect that the inclusion of satellite altimeter data has on weapon preset accuracy. GDEM data and MODAS data utilizing four satellite altimeters were used by the Weapon Acoustic Preset Program to determine the suggested presets for a Mk 48 torpedo. The acoustic coverage area generated by the program will be used as the metric to compare the two sets of outputs. The assumption is that the MODAS initialized presets will be more accurate, and, therefore, the difference between the two sets of presets can be attributed to inaccuracy on the part of the GDEM presets. Output presets were created for two different scenarios, an Anti-Surface Warfare (ASUW) scenario and an Anti-submarine Warfare (ASW) scenario, and three different depth bands, shallow, mid, and deep. After analyzing the output, it became clear that the GDEM data predicted a weapon effectiveness that was far higher than the effectiveness predicted by the MODAS data. Also, while GDEM predicted a wide range of coverage percentages MODAS predicted a narrow range of coverage percentages.

Book Synopsis Screen Dispositions of Naval Task Forces Against Anti-Ship Missiles by : Erhan Aydin
Download or read book Screen Dispositions of Naval Task Forces Against Anti-Ship Missiles written by Erhan Aydin and published by . This book was released on 2000-03 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ship defense in convoy operations against Anti-Surface Missiles (ASM) has been an important aspect of Naval Warfare for the last two decades. Countries in a state of conflict often conduct threatening operations in their own territories in order to slow or stop the enemy merchant ship traffic through the straits or littoral waters. Such littoral scenarios, the quantity and capability of ASM's in non-NATO countries pose a significant threat to the safe operation of the NATO forces in the waters off of potentially hostile shores. In these operations the goals of the tactical commander are to design an optimal reaction platform (formation) and to determine an optimal strategy that will help him in multi-threat encounters. The scope and design in most anti-air warfare studies have been limited to evaluating the effectiveness of detecting sensors and weapon systems in a regular screen formation. The proposed model's (Disposition Mission Model - DMM) characterization, however, is based on how to perform an effective, defensive disposition from a task force. In DMM we focus on usage of a graphical user interface and provide a user-friendly environment for analyzing new tactics in screen formations. The model, with its user interface, allows the user to build and run a convoy simulation, and see the results comparatively on the same interface. The analysis using this model has yielded significant insights towards the defense of a convoy by way of regression methods. It has been seen that positioning the escort ships within the threat sector reduces the damage on the HVU and also balances the defensive load of each defense ship for the incoming missiles. The model, with its graphical interface and simulation components, provides an initial approach for future analysts, not only in anti-air warfare defense of screen formations, but also in the areas of anti-surface and anti-submarine warfare.
Book Synopsis Seventy Years of Exploration in Oceanography by : Klaus Hasselmann
Download or read book Seventy Years of Exploration in Oceanography written by Klaus Hasselmann and published by Springer Science & Business Media. This book was released on 2010-04-08 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: It all began with Markus Jochum approaching one of us (HvS) – “when you guys are doing interviews with senior scientists from oceanography and related sciences, why are you not doing Walter Munk?” Indeed, why not? Walter Munk, an icon in oceanography, had just given a wonderful talk in a symposium in honor of his 90th birthday, sweeping a grand circle from his earliest work with Chip Cox on airborne measurements of ocean surface roughness to the latest satellite data – not simply a review, but the struggle of an active scientist opening up new perspectives – as inspiring and stimulating as when one of us (KH) rst met him at the Ocean Waves Conference in Easton in 1961 (Fig. I. 1). Walter immediately agreed to share with us his recollections on the nearly seventy years of his path-breaking contributions in a sheer amazing range of topics, from ocean waves, internal waves, ocean currents, tides, tsunamis, sea level, microseisms and the rotation of the earth to ocean acoustic tomography. With “you guys” Markus was referring to HvS and the various partners HvS had 1 invited to join him in conducting a series of interviews of retired colleagues.

Book Synopsis The Gathering Biological Warfare Storm by : Jim A. Davis
Download or read book The Gathering Biological Warfare Storm written by Jim A. Davis and published by Bloomsbury Publishing USA. This book was released on 2004-05-30 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new threat is stalking nations, as terrorist organizations and rogue states alike appear intent on acquiring and using the poor man's nuclear weapon: biological agents such as anthrax, smallpox, and plague. Attacks against Americans during the past dozen years may be an indication of more worrisome events to come. U.S. military forces in Japan were attacked in April of 1990 with botulinum toxin by the Aum Shinrikyo cult. Hundreds in Oregon were sickened with Salmonella after an attack in 1984. And small amounts of anthrax resulted in widespread panic and frequent evacuations across the United States in the fall of 2001. Ten experts discuss in detail the threats posed by bio-weapons and assess the current state of U.S. biological defenses. Chapters highlight the future prospects for biological warfare, bio-weapons in the Middle East, potential agroterrorism, the emerging bio-cruise missile threat, prevalent myths and likely scenarios, as well as the public health response. The promise of future world peace after World War II was quickly shattered by the Cold War. Indeed, the nuclear age was born at a time when the world seemed to be emerging from a dark past into a hopeful future. Are we to repeat history? With the end of the Cold War, does the future hold even greater threats? Or is an old threat merely resurfacing with a new level of lethality? This book should be required reading for anyone interested in national security, as well as concerned citizens who wish to know what form this new enemy may take and what can be done to stop it.

Book Synopsis A Thesaurus of English Word Roots by : Horace Gerald Danner
Download or read book A Thesaurus of English Word Roots written by Horace Gerald Danner and published by Rowman & Littlefield. This book was released on 2014-03-27 with total page 1007 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horace G. Danner’s A Thesaurus of English Word Roots is a compendium of the most-used word roots of the English language. As Timothy B. Noone notes in his foreword: “Dr. Danner’s book allows you not only to build up your passive English vocabulary, resulting in word recognition knowledge, but also gives you the rudiments for developing your active English vocabulary, making it possible to infer the meaning of words with which you are not yet acquainted. Your knowledge can now expand and will do so exponentially as your awareness of the roots in English words and your corresponding ability to decode unfamiliar words grows apace. This is the beginning of a fine mental linguistic library: so enjoy!” In A Thesaurus of English Word Roots, all word roots are listed alphabetically, along with the Greek or Latin words from which they derive, together with the roots’ original meanings. If the current meaning of an individual root differs from the original meaning, that is listed in a separate column. In the examples column, the words which contain the root are then listed, starting with their prefixes, for example, dysacousia, hyperacousia. These root-starting terms then are followed by terms where the root falls behind the word, e.g., acouesthesia and acoumeter. These words are followed by words where the root falls in the middle or the end, as in such terms as bradyacusia and odynacusis.. In this manner, A Thesaurus of English Word Roots places the word in as many word families as there are elements in the word. This work will interest linguists and philologists and anyone interested in the etymological aspects of English language.

Book Synopsis The Emerald Planet by : David Beerling
Download or read book The Emerald Planet written by David Beerling and published by Oxford University Press. This book was released on 2017-05-12 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have profoundly moulded the Earth's climate and the evolutionary trajectory of life. Far from being 'silent witnesses to the passage of time', plants are dynamic components of our world, shaping the environment throughout history as much as that environment has shaped them. In The Emerald Planet, David Beerling puts plants centre stage, revealing the crucial role they have played in driving global changes in the environment, in recording hidden facets of Earth's history, and in helping us to predict its future. His account draws together evidence from fossil plants, from experiments with their living counterparts, and from computer models of the 'Earth System', to illuminate the history of our planet and its biodiversity. This new approach reveals how plummeting carbon dioxide levels removed a barrier to the evolution of the leaf; how plants played a starring role in pushing oxygen levels upwards, allowing spectacular giant insects to thrive in the Carboniferous; and it strengthens fascinating and contentious fossil evidence for an ancient hole in the ozone layer. Along the way, Beerling introduces a lively cast of pioneering scientists from Victorian times onwards whose discoveries provided the crucial background to these and the other puzzles. This understanding of our planet's past sheds a sobering light on our own climate-changing activities, and offers clues to what our climatic and ecological futures might look like. There could be no more important time to take a close look at plants, and to understand the history of the world through the stories they tell. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.

Book Synopsis Frontiers of Fundamental Physics by : M. Barone
Download or read book Frontiers of Fundamental Physics written by M. Barone and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Olympia conference Frontiers of Fundamental Physics was a gathering of about hundred scientists who carryon their research in conceptually important areas of physical science (they do "fundamental physics"). Most of them were physicists, but also historians and philosophers of science were well represented. An important fraction of the participants could be considered "heretical" because they disagreed with the validity of one or several fundamental assumptions of modern physics. Common to all participants was an excellent scientific level coupled with a remarkable intellectual honesty: we are proud to present to the readers this certainly unique book. Alternative ways of considering fundamental matters should of course be vitally important for the progress of science, unless one wanted to admit that physics at the end of the XXth century has already obtained the final truth, a very unlikely possibility even if one accepted the doubtful idea of the existence of a "final" truth. The merits of the Olympia conference should therefore not be judged a priori in a positive or in a negative way depending on one's refusal or acceptance, respectively, but considered after reading the actual of basic principles of contemporary science, new proposals and evidences there presented. They seem very important to us.
