 Free Download Oceanic Wave Energy Conversion: Advancement of Electrical Generators by Omar Farrok, Md Rabiul Islam English | PDF EPUB (True) | 2024 | 187 Pages | ISBN : 9819998131 | 60.6 MB This book aims to collect the latest theoretical and technological ideas in design and construction for different kinds of oceanic wave energy converters including linear electrical generators and drive systems. Advancements in new wave energy converters, linear machine topologies, integrated mathematical modeling, application of high graded magnetic materials, and high-performance control strategies are of great interest. With the ability to generate direct thrust without any mechanical transmission, the linear electrical machines serve as the excellent choice for wave energy generators, free piston engine, industrial applications requiring linear motion, and so on. On the other hand, the special characteristics of linear electrical machines, such as the large air gap length, force ripples, end effects, cogging force, cut open magnetic circuit, half-filled end slot, pose a great challenge to the engineer and scientist. The challenge is not only for designing electrical machines but also for control strategies. The chapters of this book have been structured with theoretical, simulation, and experimental results in such a way that it provides a consistent compilation of fundamental theories, a compendium of current research and development activities as well as new directions to overcome critical limitations.  Free Download Natural Gas Hydrate: In Oceanic and Permafrost Environments By Robert E. Pellenbarg, Michael D. Max (auth.), Michael D. Max (eds.) 2003 | 415 Pages | ISBN: 1402013620 | PDF | 15 MB 1. THE BEGINNINGS OF HYDRATE RESEARCH Until very recently, our understanding of hydrate in the natural environment and its impact on seafloor stability, its importance as a sequester of methane, and its potential as an important mechanism in the Earth's climate change system, was masked by our lack of appreciation of the vastness of the hydrate resource. Only a few publications on naturally occurring hydrate existed prior to 1975. The first published reference to oceanic gas hydrate (Bryan and Markl, 1966) and the first publication in the scientific literature (Stoll, et a1., 1971) show how recently it has been since the topic of naturally occurring hydrate has been raised. Recently, however, the number of hydrate publications has increased substantially, reflecting increased research into hydrate topics and the initiation of funding to support the researchers. Awareness of the existence of naturally occurring gas hydrate now has spread beyond the few scientific enthusiasts who pursued knowledge about the elusive hydrate because of simple interest and lurking suspicions that hydrate would prove to be an important topic. The first national conference on gas hydrate in the U.S. was held as recently as April, 1991 at the U.S. National Center of the U.s. Geological Survey in Reston Virginia (Max et al., 1991). The meeting was co-hosted by the U.s. Geological Survey, the Naval Research Laboratory, and the U.S.  Free Download Environmental History of Oceanic Islands: Natural and Human Impacts on the Vegetation of the Juan Fernández (Robinson Crusoe) Archipelago by Tod F. Stuessy English | EPUB| 2020 | 345 Pages | ISBN : 303047870X | 143.8 MB The Juan Fernández Archipelago is located in the Pacific Ocean west of Chile at 33° S latitude. Robinson Crusoe Island is 667 km from the continent and approximately four million years old; Alejandro Selkirk Island is an additional 181 km west and only one million years old. The natural impacts of subsidence and erosion have shaped the landscapes of these islands, resulting in progressive changes to their subtropical vegetation.  Free Download Dilip M Menon, "Cosmopolitan Cultures and Oceanic Thought" English | ISBN: 1032292970 | 2023 | 280 pages | PDF | 8 MB This book imagines the ocean as central to understanding the world and its connections in history, literature and the social sciences. Introducing the central conceptual category of ocean as method, it analyzes the histories of movement and traversing across connected spaces of water and land sedimented in literary texts, folklore, local histories, autobiographies, music and performance. It explores the constant flow of people, material and ideologies across the waters and how they make their presence felt in a cosmopolitan thinking of the connections of the world. Going beyond violent histories of slavery and indenture that generate global connections, it tracks the movements of sailors, boatmen, religious teachers, merchants, and adventurers.  Terry Crowley, John Lynch, Malcolm Ross, "The Oceanic Languages" English | 2001 | ISBN: 0700711287, 0415861578 | PDF | pages: 942 | 34.2 mb This new volume of the Language Family Series presents an overview of the Oceanic subgroup of the Austronesian languages, spread across a region embracing eastern Indonesia, Melanesia, Polynesia, and Micronesia. It provides sufficient phonological and grammatical data to give typologists and comparativists a good idea of the nature of these languages, and of how much typological variety there is in this single subgroup. The references will allow those interested in particular topics, geographical areas or specific languages to delve further. Divided into two major parts, the first five chapters of the book place the Oceanic languages in their geographic, demographic and social context. Both the place of the Oceanic subgroup within the wider Austronesian family, and the internal subgrouping of Oceanic itself are dealt with. A typological overview of Oceanic languages is provided, as well as an outline of the reconstructed phonology and morphosyntax of Proto Oceanic. The second part of the book consists of grammar sketches of 43 Oceanic languages that are not at all well known in the linguistic literature. For many of these languages, the sketch in this volume is the first grammatical treatment to appear in print.

Dobrin 2021 | ISBN: 1138315273, 1138315222 | English | 254 pages | PDF | 29.5 MB This book initiates a conversation about blue ecocriticism: critical, ethical, cultural, and political positions that emerge from oceanic or aquatic frames of mind rather than traditional land-based approaches.  Oceanic Histories (Cambridge Oceanic Histories) by David Armitage, Alison Bashford English | Dec 7, 2017 | ISBN: 1108423183, 1108434827 | 338 pages | PDF | 31 MB Oceanic Histories is the first comprehensive account of world history focused not on the land but viewed through the 70% of the Earth's surface covered by water. Leading historians trace the history of the Indian, Pacific, and Atlantic Oceans and seas, from the Arctic and the Baltic to the South China Sea and the Sea of Japan/Korea's East Sea, over the longue durée. Individual chapters trace the histories and the historiographies of the various oceanic regions, with special attention given to the histories of circulation and particularity, the links between human and non-human history and the connections and comparisons between parts of the World Ocean. Showcasing oceanic history as a field with a long past and a vibrant future, these authoritative surveys, original arguments and guides to research make this volume an indispensable resource for students and scholars alike. |
