Textile fabrics and material selection of heart valves is also covered, with a section devoted to how to prioritize material selection.This is an ideal book for students and surgeons studying medicine and biomedical engineering, industry professionals working in R&D, as well as regulatory agencies, such as the FDA, SFDA, and Bureau of Medical Devices.

This brief presents the novel PHY layer technique, attachment transmission, which provides an extra control panel with minimum overhead. In addition to describing the basic mechanisms of this technique, this brief also illustrates the challenges, the theoretical model, implementation and numerous applications of attachment transmission. Extensive experiments demonstrate that attachment transmission is capable of exploiting and utilizing channel redundancy to deliver control information and thus it can provide significant support to numerous higher layer applications. The authors also address the critical problem of providing cost-effective coordination mechanisms for wireless design. The combination of new techniques and implementation advice makes this brief a valuable resource for researchers and professionals interested in wireless penetration and communication networks.

This book examines how educational change has progressed in three contrasting areas spread across China since 1990, exploring key issues concerning rural education in poor, rich and minority areas.

This book introduces readers to adaptive interference mitigation techniques based on multiple antennas for global navigation satellite systems (GNSS) in the time, domain, spatial and spatial-temporal domains. As the performance of GNSS can easily be impacted by various intentional and unintentional interferences, the book explores in detail various types of interference, including jamming , high dynamic jamming, spoofing, multipath and pulsed interference. It offers a valuable reference work for graduate students and engineers in the field of satellite navigation and signal processing.

This book highlights the principles and technology to solve the challenges of multi-target tracking in underwater target detection, with sonar equipment research as the background. While underwater acoustic target detection primarily determines the presence or absence of targets, it fails to provide the information about batches. Multi-target tracking, on the other hand, focuses on addressing issues including dividing target batches, obtaining target start and end times, obtaining information about target quantity, as well as filtering out false targets and smoothing trajectories. For sonar equipment, especially that on unmanned platforms, multi-target tracking is of utmost significance.However, due to a host of uncertainties, multi-target tracking proves extremely challenging in practical sonar applications. These uncertainties include: ① Target motion often comes with random interference, causing sensors to occasionally miss targets; ② The number of targets in the observation area fluctuates randomly; ③ Sensor observations are subject to random noise interference; ④ The quantity of sensor observations varies over time in an unpredictable manner; ⑤ Targets may be too close for sensors to distinguish; and ⑥ Sometimes, even when there are no targets in the observation area, sensors still generate observation data.To tackle these issues, this book systematically elucidates the fundamental principles of multi-target tracking algorithms and introduces a variety of such algorithms. Ultimately, although the book centers on multi-target tracking, the operation of a single sonar or multiple sonar devices aims to solve the problem of locating passive targets. This, in turn, enables the calculation of target position, heading, and speed, as well as the estimation of the target's operational status.The book is a comprehensive and in-depth reference for researchers and engineers engaged in the research and development of sonar equipment as well as graduate students in underwater acoustics.
