Chapter 9 studies the U.S.-China rivalry, which has strengthened since the early 2010s. From an evolutionary perspective, strategy is defined as a phenotype or playbook and strategic rivalry as a contest of different phenotypes in the larger ecological environment. International relations are thus fundamentally defined by competition and selection. Competition may lead to divergence among units, and the mechanism of selection indeed requires different types. The United States and China represent two different types of political systems, although there has also been mutual learning. The U.S.-China rivalry is consequential for East Asia and the world because they are currently the two greatest powers, with the sources of their power constructed and adapted over years. The chapter demonstrates how the United States and China have been in different stages since the founding of the United States in 1776, experiencing ups and downs in their bilateral interactions since 1784.

This chapter focuses on inference methods under different scenarios with an emphasis on the most general case. We introduce different methods based on smoothing methods, the self-normalization approach, and different types of bootstrap.

This chapter introduces what a time series is and defines the important decomposition into trend, seasonal, and cycle that guides our thinking. We introduce a number of datasets used in the book and plot them to show their key features in terms of these components.

Chapter 9 on siting and installation considers some of the key steps leading to the successful installation of a wind energy project, whether a single machine or large array. A section on resource assessment considers site wind measurements, the IEC Wind Classification system, and the measure-correlate-predict (MCP) procedure for establishing long-term characteristics at a prospective site. Array interactions are described in terms of energy loss and increased turbulence: empirical models are given for predicting both effects and wake influence is illustrated with field measurements from large and small arrays. The civil engineering aspects of project construction are examined, with description of different foundation types; simple rules are given for conventional gravity base design, with illustrations. The construction and environmental advantages of rock anchor foundations are described, and some examples given. Transport, access, and crane operations are discussed. The use of winch erection is illustrated with the example of a 50kW machine. The chapter concludes with a short summary of the necessary electrical infrastructure between a wind turbine and the external grid network.

This chapter contains a broad overview of the technical and environmental issues to be addressed in the contruction of onshore wind energy projects. The former include ecological considerations, including birds and mammals; the requirements of typical pre-construction ornithological surveys are described with an example. Public safety and acceptance is discussed in the context of catastrophic damage to wind turbines, visual impact, shadow flicker, and noise nuisance. In the last case equations and simple rules for noise assessment are given in the context of typical planning guidelines. Sound power levels for a range of commercial wind turbines are compared, and empirical relationships given relating noise to rated output, and rotor size and tip speed. Risks to aviation are discussed, covering aircraft collision and interference to radar systems, including both primary and secondary surveillance radars. The concept of ‘stealthy’ wind turbine blades is discussed, and described in outline. Other siting criteria include avoidance of RF and microwave communications beams and television interference. Rules are given to avoid interference, while minimising required separation distances.

Chapter 3 examines mythical, historical, and scientific facts. It offers a brief history of East Asian international relations, paying particular attention to the Chinese World Order, the Khmer Empire, and post-colonial Filipino historiography as samples for how to theorize histories from an IR perspective. The chapter discusses war and peace as well as political economy, the subject matters important for East Asian history and IR theory. It also offers a section on impacts and lessons of history, illustrating how history contributes to background knowledge, historiography and belief systems, foreign policy analysis, and IR theory. A better understanding of East Asian history allows us to contextualize contemporary issues without which we may not be able to put together a puzzle. Historical experiences inform our belief system, into which people typically fit new events or factors as explanation. History is evolutionary by nature, whether we frame it that way explicitly or not.

This chapter summarises the key aerodynamic theory of horizontal-axis wind turbine rotors. The actuator disc concept leads to the relationships between induced velocity, axial thrust, and power extraction. The theory is extended to multiple streamtubes, which combined with 2D wing theory establish the basis of blade element momentum (BEM) theory. A straightforward mathematical treatment of BEM theory is included, with an iterative procedure suitable for coding. Measurements from a full-scale rotor illustrate the applicability of BEM theory but also its fundamental limitations: the latter are described, and measures outlined to compensate for them in practical BEM codes. Simple relationships are given for the axial and tangential load distributions on an optimal HAWT blade. The structure of the rotor wake is described, leading into a description of vortex-wake theory, which provides a more physically realistic description of the airflow. Vortex wake codes are described in non-mathematical terms. The chapter includes wake measurements from full-scale wind turbines and small models. Vorticity maps from the latter verify the underlying mathematical model of a helical vortex wake.
