Social media platforms have been pivotal in redefining the conduct of contemporary society. Amid the proliferation of a range of new and ubiquitous online platforms, YouTube, a video-based platform, remains a key driver in the democratisation of creative, playful, vernacular, intimate, as well as political expressions. As a critical node of contemporary communication and digital cultures, its steady uptake and appropriation in a social media-savvy nation such as the Philippines requires a critical examination of its role in the continued reconstruction of identities, communities, and broader social institutions. This book closely analyses the diverse content and practices of amateur Filipino YouTubers, exposing and problematising the dynamics of brokering the contested aspirational logics of beauty and selfhood, interracial relationships, world-class labour, and progressive governance in a digital sphere. Ultimately, Philippine Digital Cultures: Brokerage Dynamics on YouTube offers a fresh, compelling, and nuanced account of YouTube as an important site for the mediation of culture, economy, and politics in Philippine postcolonial modernity amid rapid economic globalisation and digitalisation.

A photonic integrated circuit (PIC) can be seen as a 'light-based' analogue of an electronic circuit (i.e. where functionality occurs by manipulation of light rather than electrical current). Much research has gone into this area and this well-organised book sheds light on the technology behind PICs and the capabilities of the various platforms available. It provides an engineering approach to photonic integration technologies from the fundamental concepts, through to assembly issues and the integration strategies to combine different components in a single chip.

Physical Biometrics for Hardware Security of DSP and Machine Learning Coprocessors presents state-of-the art explanations for detective control-based security and protection of digital signal processing (DSP) and machine learning coprocessors against hardware threats. Such threats include intellectual property (IP) abuse and misuse, for example, fraudulent claims of IP ownership and IP piracy. DSP coprocessors such as finite impulse response filters, image processing filters, discrete Fourier transform, and JPEG compression hardware are extensively utilized in several real-life applications. Further, machine learning coprocessors such as convolutional neural network (CNN) hardware IP cores play a vital role in several applications such as face recognition, medical imaging, autonomous driving, and biometric authentication, amongst others.

The aim has been to provide an up-to-date analysis of the theoretical and practical problems involved in circuit breaker design. Circuit breakers present very special design problems because of the wide mixture of experience required.

Power electronics converters are devices that change parameters of electric power, such as voltage and frequency, as well as between AC and DC. They are essential parts of both advanced drives, for machines and vehicles, and energy systems to meet required flexibility and efficiency criteria. In energy systems both stationary and mobile, control and converters help ensure reliability and quality of electric power supplies.

This book provides a practical and comprehensive analysis of control systems for boilers and HRSGs (heat-recovery steam generators) in a variety of applications from waste-to-energy plants through to combined-cycle gas-turbine power stations (CCGTs).

Accurate knowledge of electromagnetic power system transients is crucial to the operation of an economic, efficient and environmentally-friendly power system network, without compromising on the reliability and quality of the electrical power supply. Simulation has become a universal tool for the analysis of power system electromagnetic transients and yet is rarely covered in-depth in undergraduate programmes. It is likely to become core material in future courses.

Practical Communication Theory, 2nd Edition enables the reader to quickly and easily generate the answers to real-world problems encountered in specifying, testing, and fielding any type of systems that involve radio propagation. It deals with free space radio propagation and propagation near the ground and over the ridge lines. As a bonus, this book also includes a special antenna and propagation slide rule, with unique scales, along with detailed explanations, and examples, of how to use it.

Principles of Microwave Circuits is an unabridged reprint of the book first published in 1948 by McGraw Hill as Volume 8 of the MIT Radiation Laboratory Series. Since the original publication of this book, a number of errors have been brought to our attention. Corrections of these errors are incorporated in this edition.

With this book engineers will understand the fundamental theoretical bases of modern microwave measurements. The narrative is firmly based on the principles of swept frequency techniques, though single frequency measurements, for instance of power, are also fully covered. By the use of flowgraph techniques and careful approximations, the author has given physical meaning to the mathematical arguments and has been careful to show the practical and theoretical limitations on measurement accuracy. The book covers a wide range of microwave measurements in the time and frequency domains, including reflectometry, the Smith chart, spectrum analysers, vector and scalar analysers, multiports, power, noise, frequency stability, time domain reflectometry, and a comprehensive account of antenna far and near field measurements. It is particularly recommended for young engineers requiring a good background in microwave measurement principles and will also be a useful reference for more experienced engineers.

The intention is to present a summary of the state of knowledge in the microwave propagation field at the close of the war. There has been no attempt to produce either a handbook or textbook, but only an interim report on a rapidly changing subject. An attempt has been made to survey all relevant information that was available, from whatever source, and to summarise as much of it as was feasible.

This book describes new, highly effective, rigorous analysis methods for electromagnetic wave problems. Examples of their application to the mathematical modelling of micros trip lines, corrugated flexible waveguides, horn antennas, complex-shaped cavity resonators and periodic structures are considered.
