Describes the outphasing approach to amplifier linearization that uses power-combining techniques to create a linear output waveform from two nonlinear input sources, and presents recent advances in resolving the limitations caused by the strict matching requirements between the two amplifiers and the microwave power wasted in the power-combing network. The authors discuss the linearity performance of outphasing amplifier systems, correction schemes based on training vectors, and power recycling in outphasing amplifiers.

The meteoric rise of the photovoltaic (PV) industry is an incredible story. In 2013, Google’s investments in PV systems totaled about half a billion dollars and Warren Buffet, one of the famous investors, invested $2.5 billion in the world’s largest PV system in California. These gigantic investments by major financial players were made only 40 years after the first two terrestrial PV companies, Solarex and Solar Power Corporation, were formed in the USA. Back in 1973, the two companies employed 20 people and produced only 500 watts of PV power. Now, just 40 years later, over a million people work in the PV industry. The worldwide capacity of operating PV electric generators equals the capacity of about 25 nuclear power plants. The PV industry is growing at an annual rate of 30 percent, equivalent to about five new nuclear power plants per year. Today, solar electricity is a significant supplier of electricity needs, to the extent that PV is forcing the restructuring of 100-year-old electric power utilities. This book describes how this happened and what lies ahead for PV power generation.
This book seeks to re-appreciate the concept of customary international law as a form of spontaneous societal self-organisation, and to develop the methodological consequences that ensue from this conception for the practice of its application. In pursuing this aim, the author draws from three different strands of scholarship that have not yet been considered in connection with one another: First, general jurisprudential theories of customary law; second, theories of customary international law, especially as they relate to international relations scholarship; and third, methodological approaches to the interpretation of international law. This expansive, philosophical layout of the book enables the author to put the conceptual enigmas of customary international law into a broader perspective. Among the issues discussed in the book are the dichotomy of its traditional and modern forms and the respective benefits and disadvantages of inductive and deductive approaches to its ascertainment. In the course of this analysis, the author draws insights from Friedrich August Hayek’s theory of law as a ‘spontaneous order’, an information-processing device which enables the participants of a legal system to make use of decentralised knowledge. The book argues that the major advantage of custom as a source of international law lies in the fact that it is the result of a gradual process of trial and error, rather than the product of deliberate planning. This makes it a particularly apposite source of law in a time of seismic shifts in the distribution of power within a vastly diverse community of States, when a new global order is expected to emerge, the contours of which are not yet clearly discernible. This book applies general concepts of legal philosophy to explain the continuing relevance of custom as a source of international law while at the same time inferring from this theoretical framework concrete practical and methodological consequences, the most important of which is the special role that purposive interpretation plays with respect to rules of international custom. Given this broad approach, the book will be of interest to several groups of potential readers including academics interested in the philosophy of customary law in general, academic international lawyers and legal practitioners, especially judges, scholars of international relations and all those interested in how the international community of States organises itself.

Canal and River Levées covers the fundamental principles of canal embankments and levées calculation and design. Canal embankments and levées are amongst the world's oldest hydroengineering structures. This book is divided into seven chapters that focus on solving the problems of protecting control levees, which sometimes called anti-flood or anti-inundation dykes. The opening chapter surveys the general problems of dam design and construction. The next chapters deal with the basic characteristics, determination, experimental methods, and calculations of seepage, as well as the stability calculations and embankment settlement. These topics are followed by discussions of the local conditions and demands relating to the construction of embankments and their various concrete structures. Other chapters explore the requirements of power- and irrigation-canal sealing and the subsoil protection of levees. The last chapter looks into the measurements, general requirements, and observation of dams and levees. This book is intended primarily for civil engineering designers.

Despite its continuing popularity, the so-called standard circuit model of compound semiconductor field-effect transistors (FETs) and high electron mobility transistors (HEMTs) is shown to have a limitation for nonlinear analysis and design: it is valid only in the static limit. When the voltages and currents are time-varying, as they must be for these devices to have any practical use, the model progressively fails for higher specification circuits. This book shows how to reform the standard model to render it fully compliant with the way FETs and HEMTs actually function, thus rendering it valid dynamically. Proof-of-principle is demonstrated for several practical circuits, including a frequency doubler and amplifiers with demanding performance criteria. Methods for extracting both the reformulated model and the standard model are described, including a scheme for re-constructing from S-parameters the bias-dependent dynamic (or RF) I(V) characteristics along which devices work in real-world applications, and as needed for the design of nonlinear circuits using harmonic-balance and time-domain simulators. The book includes a historical review of how variations on the standard model theme evolved, leading up to one of the most widely used—the Angelov (or Chalmers) model.
