In this chapter, electromigration is formulated as a phenomenon of mass transport in metals under an electrical current driving force within the framework of irreversible thermodynamics. Based on this approach, the solute effect on electromigration is analyzed by considering the correlation in atomic jumping processes, a problem that is of interest to understand how solute addition can affect electromigration in metals. This is followed by a review of the theory of the electromigration driving force and a discussion of the controversy of the electron screening effect. This chapter is concluded by reviewing the results on substitutional and interstitial electromigration in bulk metals.

In "The Reasonableness of Christianity," Locke aimed to promote the practice of morality and the development of moral character through a Scripture-based theological ethics. He claimed that his account of Christianity was based on Scripture alone, which he regarded as an authoritative source of historical and eschatological truth entailing moral principles. However, his writings on religion denote many similarities with Socinianism and Arminianism. He adopted Socinus’s proof of scriptural authority, highlighting the excellence of Christ’s moral precepts, insisting on the fulfillment of Old Testament Messianic prophecies in the New Testament, and describing Christ’s miracles as confirming his Messianic mission. This proof enabled Locke to develop a historical method of biblical interpretation, which, stressing the internal consistency of the Bible, considered the biblical texts in relation to both their respective historical contexts and the biblical discourse as a whole. In reading Scripture, he followed the Protestant tradition of the way of fundamentals, but he formulated an original doctrine of the fundamentals of Christianity – that is,repentance, obedience, and faith.

This chapter addresses the topic of personal property. It first addresses the fundamental notion of property. It then explores how the scope of personal property has become more expansive as novel challenges to existing notions of property have arisen over time. The chapter considers the important distinction between real property and personal property. Sub-classifications of personal property are considered, including the distinction between chattels real and personal, choses in action and choses in possession. The chapter explores various types of possession and interference with possession giving rise to actions for trespass, conversion and detinue. The chapter concludes with a discussion of how the nature of personal property rights can be lost through intermixture, accession or by becoming a fixture.

This chapter addresses the fundamental rules of contract law and introduces nine of the significant regulators operating within the Australian commercial landscape. Contracts are of enormous importance in most established economies as they provide a means by which promises made as part of a commercial bargain can be legally enforced. Contracts also underlie a large number of transactions entered into by the principal commercial regulators in this country, and so the chapter provides a useful backdrop against which we can explore more specific concepts in Australian commercial law.

Chapter 7 considers structural loading and response of horizontal-axis machines, with some theoretical background and illustrative measurements from different wind turbine types. The chapter begins with a recap of the dynamics of a single degree of freedom system, leading into a discussion of multi-DOF systems and modal analysis. The cyclic loads affecting a wind turbine structure are described, including wind shear, tower shadow, and rotationally sampled turbulence. The concepts of stochastic and deterministic loading are explained and the principle of aerodynamic damping illustrated. Qualitative descriptions are given of gyroscopic, centrifugal, and electromechanical loading. The phenomenon of blade edgewise stall vibration is explained, with discussion of mechanical damper solutions. The last part of the chapter draws on an early experimental campaign in which the dynamic loading on a full-scale wind turbine was measured and compared with the results of software simulation. Results from the same trials also demonstrate the difference in rotor thrust loading arising from positive and negative pitch control. The chapter concludes with a brief summary of fatigue prediction methods.

Chapter 5 deals with electrical issues and is broadly divided in two. The first half explains the operating principles of the several different types of generator found on wind turbines and their influence on dynamics and electrical power quality. Generator types are illustrated schematically and their characteristics explained using simple physical principles. Geared and gearless (direct drive) generators are discussed, and there is a brief historical review of generator developments. The second half of the chapter deals with electrical networks and further examines the issue of power quality. The importance of reactive power and how modern generators can manipulate it to aid voltage stability are explained; the role of external devices such as Statcoms, SVCs, and pre-insertion resistors is also discussed in this context. Measurements from a MW-scale wind turbine illustrate voltage control via reactive power management over a period of several days. The challenge of low grid strength is illustrated with a practical example of a small wind farm development on a rural network with low fault level. The chapter concludes with a brief discussion of wind turbine lightning protection.
