Book excerpt: This book explains the philosophy of the polar encoding and decoding technique. Polar codes are one of the most recently discovered capacity-achieving channel codes. What sets them apart from other channel codes is the fact that polar codes are designed mathematically and their performance is mathematically proven. The book develops related fundamental concepts from information theory, such as entropy, mutual information, and channel capacity. It then explains the successive cancellation decoding logic and provides the necessary formulas, moving on to demonstrate the successive cancellation decoding operation with a tree structure. It also demonstrates the calculation of split channel capacities when polar codes are employed for binary erasure channels, and explains the mathematical formulation of successive cancellation decoding for polar codes. In closing, the book presents and proves the channel polarization theorem, before mathematically analyzing the performance of polar codes.

Book excerpt: The International Code for Ships Operating in Polar Waters has been developed to supplement existing IMO instruments in order to increase the safety of ships' operation and mitigate the impact on the people and environment in the remote, vulnerable and potentially harsh polar waters. The Code acknowledges that polar water operation may impose additional demands on ships, their systems and operation beyond the existing requirements of the International Convention for the Safety of Life at Sea (SOLAS), 1974, the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto as amended by the 1997 Protocol (MARPOL), and other relevant binding IMO instruments. The Code acknowledges that the polar waters impose additional navigational demands beyond those normally encountered. In many areas, the chart coverage may not currently be adequate for coastal navigation. It is recognised even existing charts may be subject to unsurveyed and uncharted shoals. The Code also acknowledges that coastal communities in the Arctic could be, and that polar ecosystems are, vulnerable to human activities, such as ship operation. The relationship between the additional safety measures and the protection of the environment is acknowledged as any safety measure taken to reduce the probability of an accident, will largely benefit the environment. While Arctic and Antarctic waters have similarities, there are also significant differences. Hence, although the Code is intended to apply as a whole to both Arctic and Antarctic, the legal and geographical differences between the two areas have been taken into account. The key principles for developing the Polar Code have been to use a risk-based approach in determining scope and to adopt a holistic approach in reducing identified risks. It will come into effect only in 2017 for new ships and 2018 for existing ships.

Available in PDF, EPUB and Kindle. Book excerpt: 'Global Commons’ refers to resource domains or areas that lie outside of the political reach of any one State, including sea areas beyond national jurisdiction and Antarctica. The concept of ‘global commons’ is a living concept and can accommodate, over time, other commons at the international level, such as biodiversity and generic resources. The outlook for the global marine commons is not encouraging: fishery resources continue to deplete, marine biodiversity continues to reduce, and plastic wastes in the oceans continue to increase. In international law, there are legal regimes governing global marine commons, the most important of which is the 1982 United Nations Convention on the Law of the Sea (LOSC). Effective as of 1994 LOSC governs the high seas, international seabed and its resources, marine environmental protection, and fisheries. Global Commons and the Law of the Sea offers intellectual discussions on global marine commons. It contains six parts respectively addressing the principle of the common heritage of mankind (CHM), freedoms of high seas, deep sea mining and international seabed, area beyond national jurisdiction (ABNJ) governance, management of geoengineering and generic resources, and recent developments in the polar regions.

Available in PDF, EPUB and Kindle. Book excerpt: The 1982 United Nations Convention on the Law of the Sea (UNCLOS) has for four decades been considered by many to be one of the most important legislative achievements of international law. It is revered as a "constitution of the oceans", providing the legal framework for the governance of the oceans. This volume explores how the UNCLOS is functioning in various complex settings, how it adapts to new, emerging developments, as well as how it interacts with other regulation, both within the law of the sea regime and outside. Engaging in themes such as law and order at sea, UNCLOS’ interaction with human rights and the role of private actors, the book raises complex questions in the application, understanding, and enforcement of the convention and how it can be envisaged, interpreted, and used in a dynamic world. The volume also raises methodological questions, the answers to which may enhance the predictability and coherence of the law under UNCLOS and thus secure its role as the predominant and relevant system for legal governance at sea for many decades to come. As a contribution to ensuring the future relevance of UNCLOS, the book will be a valuable resource for scholars, diplomats, judges and other practitioners who are working with and interpreting the law of the sea and related issues of maritime law, migration law, human rights law and humanitarian law.

Available in PDF, EPUB and Kindle. Book excerpt: Treats joint source and channel decoding in an integrated way Gives a clear description of the problems in the field together with the mathematical tools for their solution Contains many detailed examples useful for practical applications of the theory to video broadcasting over mobile and wireless networks Traditionally, cross-layer and joint source-channel coding were seen as incompatible with classically structured networks but recent advances in theory changed this situation. Joint source-channel decoding is now seen as a viable alternative to separate decoding of source and channel codes, if the protocol layers are taken into account. A joint source/protocol/channel approach is thus addressed in this book: all levels of the protocol stack are considered, showing how the information in each layer influences the others. This book provides the tools to show how cross-layer and joint source-channel coding and decoding are now compatible with present-day mobile and wireless networks, with a particular application to the key area of video transmission to mobiles. Typical applications are broadcasting, or point-to-point delivery of multimedia contents, which are very timely in the context of the current development of mobile services such as audio (MPEG4 AAC) or video (H263, H264) transmission using recent wireless transmission standards (DVH-H, DVB-SH, WiMAX, LTE). This cross-disciplinary book is ideal for graduate students, researchers, and more generally professionals working either in signal processing for communications or in networking applications, interested in reliable multimedia transmission. This book is also of interest to people involved in cross-layer optimization of mobile networks. Its content may provide them with other points of view on their optimization problem, enlarging the set of tools which they could use. Pierre Duhamel is director of research at CNRS/ LSS and has previously held research positions at Thomson-CSF, CNET, and ENST, where he was head of the Signal and Image Processing Department. He has served as chairman of the DSP committee and associate Editor of the IEEE Transactions on Signal Processing and Signal Processing Letters, as well as acting as a co-chair at MMSP and ICASSP conferences. He was awarded the Grand Prix France Telecom by the French Science Academy in 2000. He is co-author of more than 80 papers in international journals, 250 conference proceedings, and 28 patents. Michel Kieffer is an assistant professor in signal processing for communications at the Université Paris-Sud and a researcher at the Laboratoire des Signaux et Systèmes, Gif-sur-Yvette, France. His research interests are in joint source-channel coding and decoding techniques for the reliable transmission of multimedia contents. He serves as associate editor of Signal Processing (Elsevier).

Available in PDF, EPUB and Kindle. Book excerpt: The freezing ecosystem in the far north of the globe is home to many different kinds of animals. They can be Strong, like a walrus Tough, like a lemming Resilient, like an arctic fox But no arctic animal is as iconic as the polar bear. Unfortunately, the endangered polar bear is threatened with extinction due to rapid climate change that is causing the ice where it hunts/lives to melt at an alarming rate. If Polar Bears Disappeared uses accessible, charming art to explore what would happen if the sea ice melts, causing the extinction of polar bears, and how it would affect environments around the globe.
