Miscellaneous

The text contained in this publication describes the state-of-the-art in the field of the friction and resistance reduction techniques for crafts and bodies that operate in liquids and under the free surface. The volume is expected to be very useful for the professionals with the relevant background, namely in fluid dynamics.

The active resistance control includes a discussion specifically concerning the friction resistance, for instance via the injection of gas forming air layers and polymers initially residing adjacent to the hull. The publication is discussing the passive resistance control commonly achieved through the changes in the shape of the hull together with its appendages covering the application of different lifting bodies, as well as stern flaps and bulbous bows of the ships. The authors have also addressed the passive skin friction reduction through application of various special hull coatings plus other elements of the ship hull husbandry.

The content of the volume will definitely be of great interest to the professionals including practicing engineers, specialists and researchers in various fields of tribology, fluid mechanics and mechanical engineering, as well as to the students of relevant disciplines. Note that the authors are the world leaders in the field of the drag reduction so one will definitely suggest that the book is worth time spent.

The authors of this classic work have declared several purposes but the main and major was to provide all interested readers, and particularly students/teachers with enough comprehensive and practically useful compilation of different progressive problems which commonly embody the fundamental principles and also the real examples directly related to the practical mechanical drawing.

All of those problems have been offered in the form of some specification sheets and, in addition to that, a lay-out sheet from which the students are supposed to build the completed drawing. The referenced specification sheets, in turn, are providing a statement of the problem; they are, in most cases, supplemented with some text matter that bear upon and emphasize the things to be taught in the problems, or providing some relevant technical information. The proper utilization of the proposed specifications plus the reference sheets is expected to facilitate the moving towards the creation of the necessary level of self-reliance and the personal efforts of the students.

All of the problems chosen for inclusion into this publication have been fully supplemented and such approach has made the content of this volume very flexible. The reference sheets contained in the book are made use throughout all docs and will definitely be among the valuable features of this title.

The broad area of the wave structure interaction is considered one of the top important branches of fluid mechanics deservedly assumed to be of special significance because of the numerous applications in the fields of marine technology as well as arctic engineering.

The main objective of the present monograph is to provide readers with a modern account of different mathematical techniques related to the problems of wave structure interactions and dealing with the initial and boundary value problems that are commonly associated with the Laplace equation which, in turn, satisfies the boundary conditions of the higher order.

The author has made all efforts to present the content in a very pedagogical and easy-to-follow manner so that the readers can appreciate the tools discussed in the monograph and properly apply these tools to solve their problems in the relating branches.

Certain exercises are there at the end of each chapter; but note that some of those exercises are not attempted for solution so far. The main material of the book has been arranged in seven big chapters on the basis of the application of different mat techniques as physical problems discussed. A very useful one for all persons with the interest in the application of mathematics to engineering.

The present official Manual has been released in full accordance with the decisions of the 8th World Meteorological Congress. The publication has been specifically designed with the intention to facilitate due international collaboration of MMS, i.e. marine meteorological services, and also specify the main obligations, and also to make sure the conformity is there in the established procedures and practices which are commonly employed to achieving the above mentioned purposes.

The Manual consists of two volumes covering the global and regional MMS aspects. The first volume has been arranged in four parts containing all required regulatory materials directly related to the fundamental international obligations; it shall be taken into consideration that any additional obligations for national activities will be met as per the local procedures and practices. The layout of the first part of the manual consists of four chapters covering, apart from the introductory information, the meteorological services for the high seas, coastal and offshore areas, main ports and harbor areas, and, finally, training in the field of the marine meteorology.

The intro chapter addresses the types of regulations, procedures and declared purposes, principles of MMS, organization, notes and appendices. The second part covers the MMS of different regions of the world.

A reproduction of the very rare classic manuals covering the techniques for grinding the high speed steels demonstrating proper angles and also providing readers with the information on correct set-up of different types of bits; it also shows the correct angles the bits on the lathe are to be set. Moreover, it contains necessary instructions relating to the set-up for the tool holders.

For more than a century this volume has been serving as a valuable source of technical knowledge giving lots of helpful information which is quite often very difficult to find elsewhere. Cutting tools are there among the critically important instruments to be considered when machining the metal in the lathe. In order to perform the metal machining in an efficient and accurate manner, workers must have proper understanding of the main principles.

The booklet contains the very latest shop practices for grinding different types of the cutter bits. In fact, cutter bit is exactly a part of the lathe tool cutting the metal that is required to be removed in order to bring the work to the size and shape that are desired. They are usually made of high-speed steels and commonly held in a holder. Note that this is professionally prepared electronic copy of the publication released in the very beginning of the last century.

This book was written to help all interested readers discover the whole exciting and ungovernable world of such weather phenomena as typhoons, hurricanes and cyclones. The history and science of cyclones around the planet have both considerably evolved since the first edition of this popular and world recognized publication was released about twenty years ago.

Among the changes made to the content of this volume we would note the improved techniques for the forecasting, increased duration and intensity of the associated records and new naming systems. The book also features many serious updates and data on the recent cyclones, typhoons and hurricanes together with the loss and devastation caused by them. We all know how destructive and deadly they were. This is a completely revised and updated edition of the book containing many photos and illustrations, plus historical events, and other information.

A generally excellent title giving readers a truly impressive amount of information related to the hurricanes as well as all related terminology using an encyclopedic layout allowing for the fast search. It is expected to be of great interest not only to a technical-related people but also to a general audience. The names of the individual storms have also been provided.
