Propagation Characterization and Channel Modeling for UAV Communications (Wireless Networks)
by Xiang Cheng Ziwei Huang Lu BaiThis book focuses on the propagation characterization and channel modeling of Unmanned Aerial Vehicle (UAV) communications. Currently, there are no books that cover this specific topic. The authors fill in this void by elaborating accurate yet easy-to-use UAV channel models. The authors also present such topics as propagation characteristics of UAV communications, a time stationary regular-shaped geometry-based stochastic model (RS-GBSM) for UAV narrowband channels. It also introduces a time non-stationary RS-GBSM for UAV narrowband channels, a time non-stationary RS-GBSM for UAV wideband channels, a time-space non-stationary irregular-shaped geometry-based stochastic model (IS-GBSM) for UAV wideband channels and more. Finally, this book closes up with some promising directions, hoping to promote future research outcomes in the field of UAV channel modeling. As the UAV technology matures rapidly, UAV communications are shifting from military development to civilian and commercial sectors. The UAV communication is widely considered as a significant and indispensable component of wireless communications. It is well known that an accurate yet easy-to-use UAV channel model is the foundation of designing a proper UAV communication system and evaluating its performance. This book also provides valuable suggestions for the design of UAV communication systems by adequately presenting the UAV propagation characterization and channel modeling. This book is mainly written for researchers and professionals working in wireless communications. Advanced-level students majoring in computer science or electrical engineering may also find the content useful as a secondary textbook.

Propagation Modeling for Wireless Communications
by Indrakshi DeyThis book introduces the various approaches and tools used for modelling different propagation environments and lays the foundation for developing a unified theoretical framework for future integrated communication networks. In the case of each type of network, the book uses basic concepts of physics, mathematics, geometry and probability theory to study the impact of the dimension and shape of the propagation environment and relative transmit-receive position on the information flow. The book provides an introduction into wireless communication systems and networks and their applications. For both systems and networks, the basic hard (encoder, modulator, etc.) and soft components (information, signal, etc.) are discussed through schematic block diagrams. Next each of the modes of communication, namely radio waves, acoustic waves, magnetic induction, optical waves, biological particles (molecules, aerosols, neural synapse etc.) and quantum field, are discussed. For each communication scenario presented, the impact of different environmental factors on the propagation phenomenon is articulated, followed by different channel modelling (deterministic, analytical, and stochastic) techniques that are used to characterize the propagation environment. Finally future trends in wireless communication networks are examined and envisioned for next generations 6G/7G of communication systems, like space information networks, sea-to-sky internet of vehicles, and internet of bio-nano things. Based on the future trends of integrated networks, the book drives the need for a generalized channel model irrespective of the media and mode of information transfer. The primary audience for the book is post-graduate students, researchers and academics in electronics and communications engineering, electrical engineering and computer science.

Properties and Characterization of Modern Materials
by Andreas Öchsner Holm AltenbachThis book focuses on robust characterization and prediction methods for materials in technical applications as well as the materials' safety features during operation. In particular, it presents methods for reliably predicting material properties, an aspect that is becoming increasingly important as engineering materials are pushed closer and closer to their limits to boost the performance of machines and structures. To increase their engineering value, components are now designed under the consideration of their multiphysical properties and functions, which requires much more intensive investigation and characterization of these materials. The materials covered in this monograph range from metal-based groups such as lightweight alloys, to advanced high-strength steels and modern titanium alloys. Furthermore, a wide range of polymers and composite materials (e. g. with micro- and nanoparticles or fibres) is covered. The book explores methods for property prediction from classical mechanical characterization-related fields of application, for example, from wear, creep, fatigue and crack growth, to specific surface properties, to dielectric and electrochemical values. As in all fields of modern engineering, the process is often accompanied by numerical simulation and optimization.

The author’s work breaks new ground in the understanding of a number of 2D crystals, including atomically thin transition metal dichalcogenides, graphene, and their heterostructures, that are technologically important to next-generation electronics. In addition to critical new results on the direct growth of 2D heterostructures, it also details growth mechanisms, surface science, and device applications of “epi-grade” 2D semiconductors, which are essential to low-power electronics, as well as for extending Moore’s law. Most importantly, it provides an effective alternative to mechanically exfoliate 2D layers for practical applications.
Properties of Water from Numerical and Experimental Perspectives
by Fausto MartelliAs the most important liquid in our life and one of the most abundant molecules in the universe, water is the least understood substance with a very rich phase diagram (at least 18 crystalline forms and two liquids) and more that 60 dynamical/thermodynamic anomalies whose origins are still under debate. Properties of Water from Numerical and Experimental Perspectives gathers together leading scientists and experts in the field of water. By merging the theoretical/computational point of view with experimental approaches, it presents a state-of-the-art description of the properties of water, enlightening the source of the anomalies of water and describing how such anomalies actively affect the functioning of biological substances.
Properties of the Color-Magnitude Diagrams of Type Ia Supernovae (Springer Theses)
by Lauren AldorotyThis thesis presents a novel analysis of a photometric observational feature of Type Ia Supernovae (SNe Ia), the most precise distance indicators available for cosmological studies. While SNe Ia are crucial for understanding modern cosmology, there are systematic uncertainties associated with them that prevent use to their full potential. It is therefore vital that sources of systematic error in SN Ia standardization are better understood. In this thesis, the author robustly connects the color-magnitude diagram to SN Ia spectra and their physics for the first time, and shows that for the SN sample in the dissertation, this feature is important to consider as a contributor to scatter in the Hubble residual. There is no prior work in the literature that examines this feature in such depth, and it is rare to be able to paint such a thorough picture in a SN Ia study rooted in a single photometric feature. This work opens up many avenues for future observational and theoretical studies.
