This book presents 16 selected papers from the 7th International Conference on The Application of Physical Modelling in Coastal and Port Engineering and Science, Coastlab18. The conference was organized in Santander, Spain, from 22 to 26 May, 2018, by the Instituto de Hidráulica Ambiental de la Universidad de Cantabria, IHCantabria. Coastlab18 welcomed 175 attendees from 18 different countries. The technical program included three renowned keynote lectures and 120 presentations focused on theoretical and practical aspects related to physical modelling in the field of coastal and ocean engineering. Coastal and ocean structures, breakwaters, revetments, laboratory technologies, measurement systems, coastal field measurement and monitoring, combined physical and numerical modelling, physical modelling case studies, tsunamis, and coastal hydrodynamics were the main topics covered in the conference. This book attempts to cover, as completely as possible, all the topics presented during the conference. The papers were accepted after a peer-review process based on their full text.
The proceedings includes a selection of papers covering a range of subjects focusing on topical areas of computer networks and security with a specific emphasis of novel environments, ranging from 5G and virtualised infrastructures to Internet of things, smart environments and cyber security issues. Networking represents the underlying core of current IT systems, providing the necessary communication support for complex infrastructures. Recent years have witnessed a number of novel concepts moving from theory to large scale implementations, such as Software Defined Networking, Network Function Virtualisation, 5G, smart environments, and IoT. These concepts change fundamentally the paradigms used in traditional networking, with a number of areas such as network routing and system or business security having to adjust or redesign to accommodate them. While the benefits are clear, through the advent of new applications, use cases, improved user interaction and experience, they also introduce new challenges for generic network architectures, mobility, security, traffic engineering.

Numerical Modelling of Wave Energy Converters: State-of-the Art Techniques for Single WEC and Converter Arrays presents all the information and techniques required for the numerical modelling of a wave energy converter together with a comparative review of the different available techniques. The authors provide clear details on the subject and guidance on its use for WEC design, covering topics such as boundary element methods, frequency domain models, spectral domain models, time domain models, non linear potential flow models, CFD models, semi analytical models, phase resolving wave propagation models, phase averaging wave propagation models, parametric design and control optimization, mean annual energy yield, hydrodynamic loads assessment, and environmental impact assessment. Each chapter starts by defining the fundamental principles underlying the numerical modelling technique and finishes with a discussion of the technique's limitations and a summary of the main points in the chapter. The contents of the chapters are not limited to a description of the mathematics, but also include details and discussion of the current available tools, examples available in the literature, and verification, validation, and computational requirements. In this way, the key points of each modelling technique can be identified without having to get deeply involved in the mathematical representation that is at the core of each chapter. The book is separated into four parts. The first two parts deal with modelling single wave energy converters; the third part considers the modelling of arrays; and the final part looks at the application of the different modelling techniques to the four most common uses of numerical models. It is ideal for graduate engineers and scientists interested in numerical modelling of wave energy converters, and decision-makers who must review different modelling techniques and assess their suitability and output. - Consolidates in one volume information and techniques for the numerical modelling of wave energy converters and converter arrays, which has, up until now, been spread around multiple academic journals and conference proceedings making it difficult to access - Presents a comparative review of the different numerical modelling techniques applied to wave energy converters, discussing their limitations, current available tools, examples, and verification, validation, and computational requirements - Includes practical examples and simulations available for download at the book's companion website - Identifies key points of each modelling technique without getting deeply involved in the mathematical representation
This work describes the key results of the European research project called PROVERBS to develop and implement probability-based methods for the design of monolithic coastal structures and breakwaters subject to sea wave attacks. The issues treated include the hydrodynamic, geotechnical and structural processes involved in the wave-structure-foundation interactions and in the associated failure mechanisms.
The motion of water on a uniformly sloping beach, just after a bore reaches the shore, is studied. The shllow-water equations are used to fomulate a singular hyperbolic problem, which is solved by the help of RIEMANN'S Method and of the trutural theory of quasilinear hyperbolic equations developed in gas dynmics. The shore line is found to advance suddenly with non-zero velocity and then to move up and down the beach with constant, negative acceleration. The solution s shown to contain limit lines indiating a rather unexpeted, secondary bore in the back-wsh. (Author).
The combined finite discrete element method is a relatively new computational tool aimed at problems involving static and / or dynamic behaviour of systems involving a large number of solid deformable bodies. Such problems include fragmentation using explosives (e.g rock blasting), impacts, demolition (collapsing buildings), blast loads, digging and loading processes, and powder technology. The combined finite-discrete element method - a natural extension of both discrete and finite element methods - allows researchers to model problems involving the deformability of either one solid body, a large number of bodies, or a solid body which fragments (e.g. in rock blasting applications a more or less intact rock mass is transformed into a pile of solid rock fragments of different sizes, which interact with each other). The topic is gaining in importance, and is at the forefront of some of the current efforts in computational modeling of the failure of solids. * Accompanying source codes plus input and output files available on the Internet * Important applications such as mining engineering, rock blasting and petroleum engineering * Includes practical examples of applications areas Essential reading for postgraduates, researchers and software engineers working in mechanical engineering.
This book offers a much-needed critical approach to the intelligent use of the wide variety of map projections that are rapidly and inexpensively available today. It also discusses the distortions that are immanent in any map projection. A well-chosen map projection is one in which extreme distortions are smaller than those in any other projection used to map the same area and in which the map properties match its purpose. Written by leading experts in the field, including W. Tobler, F.C. Kessler, S.E. Battersby, M.P. Finn, K.C. Clarke, V.S. Tikunov, H. Hargitai, B. Jenny and N. Frančula. This book is designed for use by laymen. The book editors are M. Lapaine and E.L. Usery, Chair and Vice-Chair, respectively, of the ICA Commission on Map Projections for the period 2011-2015.
The use of computers in cartography has made it easier for map makers to transform data from one map projection to another and experiment with alternative representations of geographical data. This has created new challenges and opportunities for map projection scientists. Small Scale Map Projection Design focuses on numerical map projection research and is written from the perspective of the map projection user. It demonstrates how advances in the measurement of map projection distortion and in the development of low error map projections can help map makers decide what type of map projection is best for their purpose, and shows how they can eventually design their own map projections.
