"This book contains a selection of research papers presented at the 11th and 12th International Ship Stability Workshops (Wageningen, 2010 and Washington DC, 2011) and the 11th International Conference on Stability of Ships and Ocean Vehicles (Athens, 2012). The book is directed toward the ship stability community and presents innovative ideas concerning the understanding of the physical nature of stability failures and methodologies for assessing ship stability. Particular interest of the readership is expected in relation with appearance of new and unconventional types of ships; assessment of stability of these ships cannot rely on the existing experience and has to be based on the first principles. As the complexity of the physical processes responsible for stability failure have increasingly made time-domain numerical simulation the main tool for stability assessment, particular emphasis is made on the development an application of such tools.
The included papers have been selected by the editorial committee and have gone through an additional review process, with at least two reviewers allocated for each. Many of the papers have been significantly updated or expanded from their original version, in order to best reflect the state of knowledge concerning stability at the time of the books publication.
The book consist of four parts: Mathematical Model of Ship Motions in Waves, Dynamics of Large Motions, Experimental Research and Requirements, Regulations and Operations. "

"Kecepatan kapal adalah suatu nilai yang penting guna untuk memenuhi standart kecepatan dinas kapal. Pengoptimalan sistem propulsi kapal adalah faktor yang perlu diperhatikan. Beberapa penelitian untuk meningkatkan sistem propulsi kapal sudah banyak dilakukan, salah satunya adalah wake equalizing ducts dan kort nozzle. Penelitian tersebut bertujuan untuk mengarahkan aliran air lebih banyak dari sisi bawah dan sisi samping lambung kapal menuju ke baling - baling kapal. Cara ini dimaksudkan agar dapat meningkatkan efisiensi baling - baling, yang nantinya akan meningkatkan kecepatan kapal secara langsung. Dengan tujuan yang sama dengan wake equalizing ducts dan kort nozzle, maka water tunnel dirancang dengan rancangan yang lebih sederhana. Water tunnel adalah suatu terowongan air berbentuk kotak lengkung yang terhubung dari bawah lambung kapal ke buritan menuju baling - baling. Water tunnel ini memanfaatkan aliran air bawah lambung kapal untuk mengubah energi mekanik menjadi energi kinetik setelah aliran air masuk ke baling - baling. Cara ini diharapkan dapat mengalirkan air lebih terarah menuju ke baling - baling, sehingga efisiensi baling - baling meningkat, yang dapat terukur langsung melalui kenaikan kecepatan kapal. Penelitian ini dilakukan dengan cara ekperimental dan simulasi untuk mengetahui fenomena yang terjadi akibat penggunaan water tunnel. Cara Eksperimental dilakukan untuk membandingkan kecepatan kapal yang terjadi antara penggunaan water tunnel dan tidak menggunakan water tunnel, dan cara simulai dilakukan guna mengetahui fenomena aliran yang terjadi di dalam water tunnel. Sehingga pada akhir penelitian didapatkan analisa kecepatan yang terjadi akibat penggunaan water tunnel pada kapal pelat datar. Dari hasil uji kecepatan secara eksperimen didapatkan kenaikan 19-32% dengan menggunakan water tunnel pada kapal pelat datar, dan dari hasil simulasi didapatkan kontur kecepatan aliran di dalam water tunnel dengan batasan pengujian yang dihasilkan.

Ship velocity is the important value to meet the standard of ship velocity service. Optimalization ship propulsion system is a factor that have to consider. Some studies to improving ship propulsion system has been done, one of study is wake equalizing ducts and kort nozzle. In this study aims to direct the flow more water fro the bottom and side of hull towards the propeller. This method is conducted to improve the efficiency propeller, that will increase the velocity of the ship directly. With the same purpose as wake equalizing ducts and kort nozzle, the water tunnel is designed with a simply design. Water tunnel is a duct of water that shaped is curve box and connected from bottom hull ship toward aft propeller. Water tunnel takes the water flow from under the hull to convert mechanical energy to be kinetic energy after the water flow enter propeller. This method is expected to drain the water more directed toward the propeller, so the efficiency would increase, which can be measured directly through the ship velocity increase. The research was done by experimental and simulation to know the phenomenon that occurs due to using water tunnel. Experiment test conducted to compare the velocity ship that happen between unsing water tunnel and not using water tunnel, and with simulation test conducted to know the flow phenomena in water tunnel. So at the end of study was obtained that analisys of the velocity result using water tunnel system on the flat plate ship. Result of the ship velocity test experiment, obtained 19-32% increase by using a water tunnel on a flat plate ship, and from simulation test result obtained the value of contours flow in the water tunnel with boundary of study result."

"Now in its second edition, this book clearly, concisely and comprehensively outlines the essence of turbulence.
In view of the absence of a theory based on first principles and adequate tools to handle the problem, the essence of turbulence, i.e. what turbulence really is from a fundamental point of view, is understood empirically through observations from nature, laboratories and direct numerical simulations rather than explained by means of conventional formalistic aspects, models, etc., resulting in pertinent issues being described at a highly theoretical level in spite of the mentioned lack of theory.
As such, the book highlights and critically reexamines fundamental issues, especially those of paradigmatic nature, related to conceptual and problematic aspects, key misconceptions and unresolved matters, and discusses why the problem is so difficult. As in the previous edition, the focus on fundamental issues is also a consequence of the view that without corresponding advances in fundamental aspects there is little chance of progress in any applications. More generally there is a desperate need for physical fundamentals of a great variety of processes in nature and technology in which turbulence plays a central role. Turbulence is omnipresent throughout the natural sciences and technology, but despite the vast sea of information available the book retains its brevity without oversimplifications, making it of interest to a broad audience."
