This book covers various fields relevant to navigation, including Earth's magnetic field, gravity field, topography, celestial polarization field, electrostatic field, and relativistic celestial field effects. It introduces the principles and applications of navigation positioning using various natural field navigation and terrain-assisted methods, including gravity field navigation positioning, geomagnetic field navigation positioning, terrain-assisted navigation positioning, polarization...

The bioprotectants market was estimated to be worth $5.5 billion in 2022, with this figure set to rise to over $11 billion by 2027. With more than 1000 products on the market, a greater understanding of how individual species/strains function as bioprotection agents is required.Advances in bioprotection of plants against diseases considers recent advances in techniques used to identify and develop fungal and bacterial bioprotection agents, including Cl...

This book highlights a comprehensive overview of research and technical advances related to parametric array loudspeakers (PALs), covering modeling and simulation, measurements, signal processing, beamsteering, and their implementations and applications. PALs that can achieve directional sound reproduction have received widespread attention from global researchers due to their advantages of narrow beam, highly directivity, and very small sidelobes. PALs have developed rapidly in theory and...

Understanding the Dynamics of Teacher Agency, Resilience, and Identity in the Neoliberal Age focuses on the complexity of teachers’ agency, resilience, and identity across various contexts. Neoliberal educational policy technologies have been constantly (re)shaping educational professionalism, subjectivity, teaching, and evaluation. Within this climate, teacher agency, resilience, and identity are vital factors for maintaining teachers’ well-functioning and well-being. Moreover, t...

While the Chinese urban movement has successfully transferred surplus labor from the countryside to urban industries that urgently require free and cheap labor, numerous problems have arisen as a result of the unprecedented huge-scale process. Such conditions such as overcrowding, substandard housing, lack of social services, corruption, and abuse of power have often reached crisis stage. American college students often ask: How does the government control the largest urban population in t...

This book summarizes recent advances in epoxy vitrimer research, giving thorough discussion of the classification and fabrication of epoxy vitrimers and their composites. Epoxy vitrimers are reversible covalently crosslinked networks with dynamic covalent bonds, combining the excellent mechanical properties of thermosets with the re-processability of thermoplastics. The authors explore and summarize many current and potential applications of epoxy vitrimer composites across the domains of ...

Inequality in health reflects the deeper social and economic structures shaping everyday life.This edited volume investigates the complex and uneven landscape of health disparities in contemporary Korean society, demonstrating how rapid economic and social transformations have produced unequal health outcomes across diverse populations. The collection highlights how factors such as employment conditions, social capital, and access to healthcare contribute to differe...

This open access book presents a comprehensive exploration of diffusion metamaterials that control energy and mass diffusion. Currently, if from the perspective of governing equations, diffusion metamaterials and wave metamaterials (pioneered by J. B. Pendry in the 1990s) are recognised as the two most prominent branches in the field of metamaterials. These two branches differ in their emphasis on the diffusion equation (as the governing equation) and time-dependent characteristic lengths ...

Upbringing and parenting runs through the child's growth process. This chapter starts with the analysis of the characteristics of parenting, and establishes a hierarchical relationship model of parenting. At the same time, it analyses the definition and connotation of each level of the model, instructing parents to recognize what resources they have in the process of upbringing and parenting, what resources can be used, and how to achieve the ideal goal of parenting and raising children. A...

This book summarizes years of research in the field of fuzzy relational programming, with a special emphasis on geometric models. It discusses the state-of-the-art in fuzzy relational geometric problems, together with key open issues that must be resolved to achieve a more efficient application of this method. Though chiefly based on research conducted by the authors, who were the first to introduce fuzzy geometric problems, it also covers important findings obtained in the field of linear...
