Reliability Based Aircraft Maintenance Optimization and Applications presents flexible and cost-effective maintenance schedules for aircraft structures, particular in composite airframes. By applying an intelligent rating system, and the back-propagation network (BPN) method and FTA technique, a new approach was created to assist users in determining inspection intervals for new aircraft structures, especially in composite structures.

This book also discusses the influence of Structure Health Monitoring (SHM) on scheduled maintenance. An integrated logic diagram establishes how to incorporate SHM into the current MSG-3 structural analysis that is based on four maintenance scenarios with gradual increasing maturity levels of SHM. The inspection intervals and the repair thresholds are adjusted according to different combinations of SHM tasks and scheduled maintenance.

This book provides a practical means for aircraft manufacturers and operators to consider the feasibility of SHM by examining labor work reduction, structural reliability variation, and maintenance cost savings.

Presents the first resource available on airframe maintenance optimization Includes the most advanced methods and technologies of maintenance engineering analysis, including first application of composite structure maintenance engineering analysis integrated with SHM Provides the latest research results of composite structure maintenance and health monitoring systems

Wireless sensor networks have a range of applications, including military uses and in environmental monitoring. When an area of interest is inaccessible by conventional means, such a network can be deployed in ways resulting in a random distribution of the sensors. Randomly Deployed Wireless Sensor Networks offers a probabilistic method to model and analyze these networks. The book considers the network design, coverage, target detection, localization and tracking of sensors in randomly deployed wireless networks, and proposes a stochastic model. It quantifies the relationship between parameters of the network and its performance, and puts forward a communication protocol. The title provides analyses and formulas, giving engineering insight into randomly deployed wireless sensor networks. Five chapters consider the analysis of coverage performance; working modes and scheduling mechanisms; the relationship between sensor behavior and network performance properties; probabilistic forwarding routing protocols; localization methods for multiple targets and target number estimation; and experiments on target localization and tracking with a Mica sensor system.

In the presence of a solid wall, the flow and thus the turbulence is directly influenced. Reduction of wall turbulence is of great significance for energy saving and environmental protection. Numerous drag control strategies have been proposed and explored during recent decades, the vast majority of which concentrate on near-wall coherent structures, which can result in significant drag reductions at low Reynolds numbers. However, whether these drag control methods can continue to be effective at high Reynolds numbers remains unresolved. This question is crucial because the flow physics involved in drag reduction changes at high Reynolds numbers (because the contribution of large-scale structures to the skin friction grows with the Reynolds number). Large-Scale Control of Wall Turbulence synthesizes and interprets research on large scale drag control. In particular it looks at the underlying physical mechanisms of the large-scale control, especially investigation of the coherent structures, and the statistical approach through the momentum flux as well as the energy flux.Covers the latest advancements in flow control technologies, particularly large-scale control techniquesComprehensive coverage: explores a wide range of flow control techniques, including active and passive methodsInterdisciplinary approach: takes an interdisciplinary approach that combines fluid mechanics, control theory, and computational methodsDemonstrates practical strategies for implementing flow control techniques in real-world scenarios

Xi Chen explores the question of why there has been a dramatic rise in and routinization of social protests in China since the early 1990s. Drawing on case studies, in-depth interviews and a unique data set of about 1,000 government records of collective petitions, this book examines how the political structure in Reform China has encouraged Chinese farmers, workers, pensioners, disabled people and demobilized soldiers to pursue their interests and claim their rights by staging collective protests. Chen suggests that routinized contentious bargaining between the government and ordinary people has remedied the weaknesses of the Chinese political system and contributed to the regime's resilience. Social Protest and Contentious Authoritarianism in China challenges the conventional wisdom that authoritarian regimes always repress popular collective protest and that popular collective action tends to destabilize authoritarian regimes.

Complexity theory aims to understand and classify computational problems, especially decision problems, according to their inherent complexity. This book uses new techniques to expand the theory for use with counting problems. The authors present dichotomy classifications for broad classes of counting problems in the realm of P and NP. Classifications are proved for partition functions of spin systems, graph homomorphisms, constraint satisfaction problems, and Holant problems. The book assumes minimal prior knowledge of computational complexity theory, developing proof techniques as needed and gradually increasing the generality and abstraction of the theory. This volume presents the theory on the Boolean domain, and includes a thorough presentation of holographic algorithms, culminating in classifications of computational problems studied in exactly solvable models from statistical mechanics.

Mechanical Self-Assembly: Science and Applications introduces a novel category of self-assembly driven by mechanical forces. This book discusses self-assembly in various types of small material structures including thin films, surfaces, and micro- and nano-wires, as well as the practice's potential application in micro and nanoelectronics, MEMS/NEMS, and biomedical engineering. The mechanical self-assembly process is inherently quick, simple, and cost-effective, as well as accessible to a large number of materials, such as curved surfaces for forming three-dimensional small structures. Mechanical self-assembly is complementary to, and sometimes offer advantages over, the traditional micro- and nano-fabrication.

Lack of clean water, inadequate sanitation, and insufficient infection prevention and control promote the spread of parasites. The discovery of antiparasitic drugs was considered a milestone in the veterinary and medical sciences, but their use has subsequently become limited due to the emergence of resistance. While plenty of attention has been given in human and animal health communities to the global threat of antimicrobial drug resistance, specific antiparasitic advice is less available. This book provides an in-depth view of the issue for parasitologists, pharmacologists and veterinary scientists. Specifically discussing antiparasitic drug resistance mechanisms and factors responsible for the problem, it covers: The physiological basis of parasitism; Resistance across protozoa, helminths, insects, mites and ticks; Molecular and phenotypic diagnostic methods; Practical strategies for mitigating resistance development. While it is clear that the veterinary field urgently requires the development of new antiparasitic drugs, of equal or even increased importance is the evaluation of alternative therapies and formulation of stringent policies to ensure appropriate drug use in veterinary practice. Highlighting the importance and development of resistance across different parasite groups, this book covers factors responsible for resistance development and advises strategies for effective stewardship and resistance mitigation.
