Time-Varying Formation Tracking Control for Nonlinear Swarm Systems
by Xiwang Dong Zhang Ren Jianglong YuThe book focuses on time-varying formation control approaches for practical nonlinear swarm systems. Time-varying formation control is the basic guarantee for performing other tasks of swarm systems, such as cooperative decision-making and cooperative detection. However, most practical swarm systems have nonlinear dynamic models. This book studies three typical models of practical nonlinear swarm systems, which represent most of the practical systems and construct the corresponding formation control structure. At the same time, the effects of disturbances, uncertain dynamics, random noise and unknown leader's input are considered and processed to improve the robustness and adaptability. The comprehensive and systematic treatment of practical nonlinear time-varying formation control issues is one of the major features of the book, which is particularly suited for readers who are interested to learn time-varying formation control solutions in nonlinear swarm systems. The book benefits researchers, engineers and graduate students in the fields of formation control, nonlinear control, robust control, etc.
Time-encoding VCO-ADCs for Integrated Systems-on-Chip: Principles, Architectures and Circuits
by Georges Gielen Luis Hernandez-Corporales Pieter RomboutsThis book demonstrates why highly-digital CMOS time-encoding analog-to-digital converters incorporating voltage-controlled oscillators (VCOs) and time-to-digital converters (TDCs) are a good alternative to traditional switched-capacitor S-D modulators for power-efficient sensor, biomedical and communications applications. The authors describe the theoretical foundations and design methodology of such time-based ADCs from the basics to the latest developments. While most analog designers might notice some resemblance to PLL design, the book clearly highlights the differences to standard PLL circuit design and illustrates the design methodology with practical circuit design examples.Describes in detail the design methodology for CMOS time-encoding analog-to-digital converters that can be integrated along with digital logic in a nanometer System on Chip;Assists analog designers with the necessary change in design paradigm, highlighting differences between designing time-based ADCs and traditional analog circuits like switched-capacitor converters and PLLs;Uses a highly-visual, tutorial approach to the topic, including many practical examples of techniques introduced.
Time-interleaved Analog-to-Digital Converters
by Simon Louwsma Ed Van Tuijl Bram NautaTime-interleaved Analog-to-Digital Converters describes the research performed on low-power time-interleaved ADCs. A detailed theoretical analysis is made of the time-interleaved Track & Hold, since it must be capable of handling signals in the GHz range with little distortion, and minimal power consumption. Timing calibration is not attractive, therefore design techniques are presented which do not require timing calibration. The design of power efficient sub-ADCs is addressed with a theoretical analysis of a successive approximation converter and a pipeline converter. It turns out that the first can consume about 10 times less power than the latter, and this conclusion is supported by literature. Time-interleaved Analog-to-Digital Converters describes the design of a high performance time-interleaved ADC, with much attention for practical design aspects, aiming at both industry and research. Measurements show best-inclass performance with a sample-rate of 1.8 GS/s, 7.9 ENOBs and a power efficiency of 1 pJ/conversion-step.

Timing Jitter in Time-of-Flight Range Imaging Cameras
by Gehan AnthonysThis book explains how depth measurements from the Time-of-Flight (ToF) range imaging cameras are influenced by the electronic timing-jitter. The author presents jitter extraction and measurement techniques for any type of ToF range imaging cameras.

The book discusses timing-jitter in the emitted light signal, which is sensible since the light signal of the camera is relatively straightforward to access. The specific types of jitter that present on the light source signal are investigated throughout the book. The book is structured across three main sections: a brief literature review, jitter measurement, and jitter influence in AMCW ToF range imaging.

Tip Streaming of Simple and Complex Fluids (Fluid Mechanics and Its Applications #137)
by José María MontaneroThis book comprehensively describes the tip streaming in simple fluids and those containing surfactants and polymeric molecules. It summarizes the theoretical models and approximations commonly adopted to analyze this phenomenon. It provides relevant experimental results and presents the scaling laws for rationalizing those results. The stability of the flows leading to tip streaming is analyzed theoretically and experimentally. Attention is paid to the effects of surfactant monolayers and viscoelasticity, including solutocapillarity, interfacial elasticity, surface viscosity, and extensional thickening caused by the polymer coil-stretch transition.It also offers an overall perspective of the numerous technological applications of the tip-streaming phenomenon. Remarkable examples are the production of microemulsions and microencapsulation of active agents for the food and pharmacy industries, the atomization of charged liquids for analytical chemistry, and the ejection of ultra-fast and ultra-thin jets for crystallography. Physical mechanisms responsible for the onset of tip streaming driven by hydrodynamic and electrohydrodynamic forces are described. Relevant theoretical and experimental results of the periodic microdripping and continuous microjetting modes of tip streaming produced with microfluidic configurations such as electrospray, flow focusing, coflowing, and selective withdrawal are discussed. The physical mechanisms responsible for the instability of the microjetting mode are studied in detail.The book collects the scaling laws used to predict the outcome of the microfluidic configurations mentioned above. The author combines state-of-the-art experimental results and linear stability analysis to identify the instability mechanisms limiting the applicability of the above-mentioned microfluidic configurations. In this way, the book connects experimental observations with fundamental aspects of tip streaming,bridging the microfluidic and fluid dynamicist communities. The connection between results obtained from the theoretical and experimental approaches will help experimentalists to understand the fundamental aspects of their practical problems. A useful guide for researchers working on hydrodynamic focusing and electrospray.
