Resorbable Fiber-Forming Polymers for Biotextile Applications

by Chirag R. Gajjar Martin W. King

This book summarizes the properties and applications of conventional and commercially available fiber-forming, bioresorbable polymers, as well as those currently under study, for use as biotextiles. Factors affecting the performance of these biomaterials are presented, and precautionary measures to reduce premature, hydrolytic degradation during manufacturing and processing are discussed. Because of the structural requirements of medical devices and the technological advancements in synthetic fibers and textile technology, the new field of "Biotextiles" has evolved to exploit the potential of various woven, knitted, braided and non-woven textile structures for biomedical applications. Textile substrates provide certain unique mechanical properties to the medical device and because of an inherently high level of porosity, they can encourage cell growth and promote migration and proliferation. Bioresorbable devices that assist in the repair and regeneration of damaged tissues have in recent years replaced many of the permanent prosthetic devices. Thus, the topic of "Bioresorbable Biomaterials" generates much interest and research activity in the field of biomaterials science today. For this reason, the use of bioresorbable polymers as fibers is currently dominating the field of resorbable biomaterials for applications from sutures to tissue engineering scaffolds.

Resource Allocation in Backscatter-Assisted Communication Networks

by Xiaozheng Gao Kai Yang Dusit Niyato Shimin Gong

This book investigates the resource allocation in backscatter-assisted communication networks. With the development of backscatter communications, integrating backscatter communication technology into traditional communication networks can improve the network performance significantly. To fully improve the performance of backscatter-assisted communication networks, resource allocation is of special importance. It is worth to mention that the resource allocation in backscatter-assisted communication networks is more challenging than that in traditional communication networks, and the tradeoff of the performance between backscatter communications and traditional communications needs to be carefully considered. In this book, considering that game theory is an attractive tool for developing and analyzing distributed, flexible, and autonomous networks, we develop the auction-based time scheduling schemes, contract-based time assignment scheme, and evolutionary game-based access point and service selection scheme for the backscatter-assisted radio-frequency-powered cognitive networks, where some important properties such as individual rationality are considered. We also employ the optimization approach and develop a relay mode selection and resource sharing scheme for backscatter-assisted hybrid relay networks to improve the throughput. We believe that the developed resource allocation schemes in this book can provide useful guidance for the design of backscatter-assisted communication networks and future Internet of Things. Graduate students, researchers, and engineers in the field of communication networks can benefit from the book.

Resource Allocation in Decentralized Systems with Strategic Agents

by Ali Kakhbod

This thesis presents a significant contribution to decentralized resource allocation problems with strategic agents. The study focused on three classes of problems arising in communication networks. (C1). Unicast service provisioning in wired networks. (C2). Multi-rate multicast service provisioning in wired networks. (C3). Power allocation and spectrum sharing in multi-user multi-channel wireless communication systems. Problems in (C1) are market problems; problems in (C2) are a combination of markets and public goods; problems in (C3) are public goods. Dr. Kakhbod developed game forms/mechanisms for unicast and multi-rate multicast service provisioning that possess specific properties. First, the allocations corresponding to all Nash equilibria (NE) of the games induced by the mechanisms are optimal solutions of the corresponding centralized allocation problems, where the objective is the maximization of the sum of the agents' utilities. Second, the strategic agents voluntarily participate in the allocation process. Third, the budget is balanced at the allocations corresponding to all NE of the game induced by the mechanism as well as at all other feasible allocations. For the power allocation and spectrum sharing problem, he developed a game form that possesses the second and third properties as detailed above along with a fourth property: the allocations corresponding to all NE of the game induced by the mechanism are Pareto optimal. The thesis contributes to the state of the art of mechanism design theory. In particular, designing efficient mechanisms for the class of problems that are a combination of markets and public goods, for the first time, have been addressed in this thesis. The exposition, although highly rigorous and technical, is elegant and insightful which makes this thesis work easily accessible to those just entering this field and will also be much appreciated by experts in the field.

Resource Extraction, Space and Resilience: International Perspectives (Routledge Studies of the Extractive Industries and Sustainable Development)

by Juha Kotilainen

While much of the current research on the extractive industries and their socio-environmental impacts is region specific, Resource Extraction, Space and Resilience: International Perspectives critically explores the current state of the extractive industries sector from a uniquely global perspective. The book introduces a more dynamic idea of sustainability in evaluating mineral extraction and its impacts, and provides a spatialized understanding of the evolution of the extractive industries to help visualise the interlinkages across space, regions and scales. Professor Kotilainen responds to these theoretical challenges by analysing the potential for resilience of mining activities from multiple perspectives across scales, exploring why it is only possible to achieve temporary balance and stability for the whole resource extraction system. Taking a global perspective, the book explores the interlinkages of the industry, investigates the similarities and differences in how the industry operates and examines the social and environmental impacts it has. By providing an explicitly theoretically informed analysis of the state of the extractive industries, this text will appeal to a wide range of scholars with an interdisciplinary interest in the extractive industries and natural resource management, including human geographers and social scientists with a focus on the relations of humans and societies with their physical environments.
