At the heart of modern power electronics converters are power semiconductor switching devices. The emergence of wide bandgap (WBG) semiconductor devices, including silicon carbide and gallium nitride, promises power electronics converters with higher efficiency, smaller size, lighter weight, and lower cost than converters using the established silicon-based devices. However, WBG devices pose new challenges for converter design and require more careful characterization, in particular due to their fast switching speed and more stringent need for protection. Characterization of Wide Bandgap Power Semiconductor Devices presents comprehensive methods with examples for the characterization of this important class of power devices. After an introduction, the book covers pulsed static characterization; junction capacitance characterization; fundamentals of dynamic characterization; gate drive for dynamic characterization; layout design and parasitic management; protection design for double pulse test; measurement and data processing for dynamic characterization; cross-talk consideration; impact of three-phase system; and topology considerations.

Reconfigurable machines can accelerate many applications by adapting to their needs through hardware reconfiguration. Partial reconfiguration allows the reconfiguration of a portion of a chip while the rest of the chip is still working. Operating system for partially reconfigurable machines (OS4RC) handles the scheduling and placement of tasks. Some existing OS4RC models assume no data exchange channel between IP (Intellectual Property) circuits residing on a FPGA chip and between an IP circuit and FPGA I/O pins. Other models assume inter-IP communication channels, but they do not work well with 2-D partial reconfiguration. And frequently they are very complicated to design and expensive. To address these problems, a new chip architecture that can better support inter-IP and IP-I/O communication is proposed and a corresponding OS4RC kernel is then specified.The proposed FPGA architecture is based on an array of clusters of CLBs, with each cluster serving as a partial reconfiguration unit, and a mesh of segmented buses that provides inter-IP and IP-I/O communication channels. Features of the new architecture can reduce the kernel execution times and enable the runtime scheduling,

Tantra is a path of personal realization that seeks to achieve a state of lasting peace--that which the mystics called illumination--while controlling their desires. Tantra is something more than a look at sex and eroticism; it is the ability to look inside people and get to know their true, natural selves, with the idea that we can love them as we love ourselves. Sexual energy is the basis of tantra, which is where this book starts. From here, we dive into the ancient discipline that will transform the reader's energy into spiritual growth.

<div> This book discusses efforts to control the low-frequency vibration transmission of typical power equipment and pipeline systems of ships, exploring the use of active and passive hybrid vibration isolation and adjustable dynamic vibration absorption technologies. It also proposes an adaptive feed-forward control strategy and studies a distributed feed-forward control hardware system. In addition, the book presents a three-way dynamic vibration absorption theory used to design a pipeline-system adjustable dynamic vibration absorber, which offers a number of advantages, such as compact structure, easy assembly and disassembly, low power consumption, excellent vibration control effect and wide frequency band adjustable ability, etc. This book is a valuable resource for researchers and engineers in the fields of noise and vibration control, active control systems, active vibration isolation and adaptive dynamic vibration absorption. </div>
