This chapter introduces the state space model and shows how this can be adapted to represent a wide variety of models of use in economics and finance. We define the Kalman filter and show how it can be implemented in leading examples.

Chapter 7 introduces students to the monetary and financial dimensions of East Asian international relations, which are fragmented regionally while tied closely with the Western-dominated monetary order. Monetary power is arguably as important as military power, but it is not well understood and not commonly included in an IR textbook. As a social construction, monetary and financial power are related to but not equivalent to productive power. East Asia does not stand in isolation, because its contemporary monetary and financial practices and theories are integrated into the global system. Thus, this chapter examines U.S. dollar hegemony. Following a broader discussion of the exchange-rate regimes adopted by East Asian nations, the chapter discusses the 1997–1998 Asian Financial Crisis, a monumental event in post-war East Asian international relations triggered by a currency crisis. The chapter ends with a discussion of the 2008 Great Recession.

The introductory chapter is a brief recap on the history and origins of wind power, from windmills in ancient times to today’s multi-megawatt turbines. Energy security has arguably been the historic driver for wind power, and it was a primary source of mechanical power until the advent of the Industrial revolution when it was superceded by coal and oil. The first electricity generating wind turbines were built in the late nineteenth centry, and the technology was pursued most vigorously in Denmark, a country with limited energy reserves: the role of this country in creating the modern wind turbine is described. The worldwide energy crisis of the 1970s brought wind power into the frame internationally, and the pivotal role of legislation under President Carter in expanding the market for wind energy in the US and elsewhere is outlined. Since then the rationale for wind power has expanded to include climate change and the technology has grown exponentially in terms of global installation of wind power and the physical size of wind turbines. The chapter concludes by introducing some of the technological steps that have enabled this process, and which are detailed in subsequent chapters.

This chapter introduces more formal concepts like stationarity and mixing, and explains why they are needed. We also define the autocorrelation function and describe its properties and how it is estimated from sample data. We discuss the properties of the estimator of the mean and autocorrelation, and how they can be used to conduct statistical inference.

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.
