Available in PDF, EPUB and Kindle. Book excerpt: After a review of the deficiencies of the usual equations of motion for an oscillating ship, two new representations are given. One makes use of the impulse response function and depends only upon the system being linear. The response is given as a convolution integral over th past history of the exciting force with the impulse response funcion appearing as the kernel. The second representation is based upon a hydrodynamic study, and new forms for the equations of motion are exhibited. The equations resemble the usual equations, with the addition of convolution integrals over the past history of the velocity. However, the coefficients in these new equations are independent of frequency, as are the kernel functions in the convolution integrals. Both representations are quite general and apply to transient motions as well as periodic. The relations between the two representations are given. The treatment considers six degrees of freedom, with linear coupling between the various modes. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the applicability of the Jacobi Function orthogonal polynomial representation of the impulse response function for the determination of ship motion from towing tank tests with irregular waves has been initiated. An analysis of the inverse Fourier transformability of the frequency domain gain and phase information obtained in lieu of time domain impulse response function is given with observations of areas of fallibility and recommendations on circumventive methods.

Download or read book Wave Energy Potential Behavior and Extraction written by Hua Li and published by MDPI. This book was released on 2020-03-27 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wave energy has a higher potential than most of the available ocean energy resources; however, it fluctuates dramatically depending on geographical and temporal baselines. The complexity of wave energy is only exacerbated by that fact that the cycle of creation, transport, and disappearance of wave energy is influenced by a wide variety of factors. This Special Issue of Energies explores the latest developments in wave energy potential, behavior, and extraction. This Special Issue introduces 1) thorough reviews on the status of wave energy development, 2) novel technologies to extract wave energy including wave energy converter design, and 3) latest methodologies applied in analyzing wave energy potentials.

Download or read book Advances in Berthing and Mooring of Ships and Offshore Structures written by E. Bratteland and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two previous NATO Advanced Study Institutes (ASI) on berthing and mooring of ships have been held; the first in Lisboa, Portugal in 1965, and the second at Wallingford, England in 1973. These ASls have contributed significantly to the under standing and development of fenders and mooring, as have works by Oil Companies International Marine Forum (1978) and PIANC (1984). Developments in ship sizes and building of new specialized terminals at very exposed locations have necessitated further advances in the combined mooring and fendering technology. Exploration and exploitation of the continental shelves have also brought about new and challenging problems, developments and solutions. Offshore activities and developments have in fluenced and improved knowledge about both ships and other floating structures which are berthed and/or moored under various environmental conditions. The scope of this ASI was to present recent advances in berth ing and mooring of ships and mooring of floating offshore structures, focusing on models and tools available with a view towards safety and reduction of frequencies and consequences of accidents.
Download or read book Electrical Measuring Instruments and Measurements written by S.C. Bhargava and published by CRC Press. This book was released on 2012-12-27 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, written for the benefit of engineering students and practicing engineers alike, is the culmination of the author's four decades of experience related to the subject of electrical measurements, comprising nearly 30 years of experimental research and more than 15 years of teaching at several engineering institutions. The unique feature of this book, apart from covering the syllabi of various universities, is the style of presentation of all important aspects and features of electrical measurements, with neatly and clearly drawn figures, diagrams and colour and b/w photos that illustrate details of instruments among other things, making the text easy to follow and comprehend. Enhancing the chapters are interspersed explanatory comments and, where necessary, footnotes to help better understanding of the chapter contents. Also, each chapter begins with a "recall" to link the subject matter with the related science or phenomenon and fundamental background. The first few chapters of the book comprise "Units, Dimensions and Standards"; "Electricity, Magnetism and Electromagnetism" and "Network Analysis". These topics form the basics of electrical measurements and provide a better understanding of the main topics discussed in later chapters. The last two chapters represent valuable assets of the book, and relate to (a) "Magnetic Measurements", describing many unique features not easily available elsewhere, a good study of which is essential for the design and development of most electric equipment – from motors to transformers and alternators, and (b) "Measurement of Non-electrical Quantities", dealing extensively with the measuring techniques of a number of variables that constitute an important requirement of engineering measurement practices. The book is supplemented by ten appendices covering various aspects dealing with the art and science of electrical measurement and of relevance to some of the topics in main chapters. Other useful features of the book include an elaborate chapter-by-chapter list of symbols, worked examples, exercises and quiz questions at the end of each chapter, and extensive authors' and subject index. This book will be of interest to all students taking courses in electrical measurements as a part of a B.Tech. in electrical engineering. Professionals in the field of electrical engineering will also find the book of use.
