Time in Control Theory: On Concepts, Measures and Uses (Synthesis Lectures on Electrical Engineering)
by Blas M. VinagreControl Theory is an interdisciplinary field of engineering and mathematics that studies the behavior of dynamic systems with external stimuli and how to modify such behavior through feedback, and the very concept of dynamic system implies the study of how the trajectories of a point in a geometric space evolve in time. Thus, time is at the very foundation of control theory, and its development and achievements are conditioned both by the conception we have of it and by our way of measuring and using it. Following a quasi-chronological order, this work aims to give an overview of how these conceptions and these ways of measuring and using time are reflected in the paths followed by control theory from its origins to the present day.

Time in Maps: From the Age of Discovery to Our Digital Era
by Caroline WintererMaps organize us in space, but they also organize us in time. Looking around the world for the last five hundred years, Time in Maps shows that today’s digital maps are only the latest effort to insert a sense of time into the spatial medium of maps. Historians Kären Wigen and Caroline Winterer have assembled leading scholars to consider how maps from all over the world have depicted time in ingenious and provocative ways. Focusing on maps created in Spanish America, Europe, the United States, and Asia, these essays take us from the Aztecs documenting the founding of Tenochtitlan, to early modern Japanese reconstructing nostalgic landscapes before Western encroachments, to nineteenth-century Americans grappling with the new concept of deep time. The book also features a defense of traditional paper maps by digital mapmaker William Rankin. With more than one hundred color maps and illustrations, Time in Maps will draw the attention of anyone interested in cartographic history.
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.

Time Lord
by Clark BlaiseIt is difficult today to imagine life before standard time was established in 1884. In the middle of the nineteenth century, for example, there were 144 official time zones in North America alone. The confusion that ensued, especially among the burgeoning railroad companies, was an hourly comedy of errors that ultimately threatened to impede progress. The creation of standard time, with its two dozen global time zones, is one of the great inventions of the Victorian Era, yet it has been largely taken for granted.In Time Lord, Clark Blaise re-creates the life of Sanford Fleming, who struggled to convince the world to accept standard time. It's a fascinating story of science, politics, nationalism, and the determined vision of one man who changed the world. Set in a time marked by substantial technological and cultural transformation, Time Lord is also an erudite exploration of art, literature, consciousness, and our changing relationship to timeFrom the Trade Paperback edition.

Time Multiplexed Beam-Forming with Space-Frequency Transformation
by Arthur H.M. van Roermund Wei Deng Reza MahmoudiThis book describes a unique approach to smart receiver system design. It starts with the analysis of a very basic, single-path receiver structure, then using similar methods, extends the analysis to a more complicated multi-path receiver. Within the multi-path structure, two different types of phased -array architectures are discussed: Analog beam-forming, and digital beam-forming. The pros and cons are studied, and the gaps are identified. Whereas previous books in this area focus mainly on phased-array circuit implementations, this book fills a gap by providing a system-level approach and introduces new methods for developing smart systems.

Time Optimal Control of Evolution Equations (Progress in Nonlinear Differential Equations and Their Applications #92)
by Gengsheng Wang Lijuan Wang Yashan Xu Yubiao ZhangThis monograph develops a framework for time-optimal control problems, focusing on minimal and maximal time-optimal controls for linear-controlled evolution equations. Its use in optimal control provides a welcome update to Fattorini’s work on time-optimal and norm-optimal control problems. By discussing the best way of representing various control problems and equivalence among them, this systematic study gives readers the tools they need to solve practical problems in control. After introducing preliminaries in functional analysis, evolution equations, and controllability and observability estimates, the authors present their time-optimal control framework, which consists of four elements: a controlled system, a control constraint set, a starting set, and an ending set. From there, they use their framework to address areas of recent development in time-optimal control, including the existence of admissible controls and optimal controls, Pontryagin’s maximum principle for optimal controls, the equivalence of different optimal control problems, and bang-bang properties.This monograph will appeal to researchers and graduate students in time-optimal control theory, as well as related areas of controllability and dynamic programming. For ease of reference, the text itself is self-contained on the topic of time-optimal control. Frequent examples throughout clarify the applications of theorems and definitions, although experience with functional analysis and differential equations will be useful.
