Book Description
This monograph describes the Reaction Wheel Pendulum, the newest inverted-pendulum-like device for control education and research. We discuss the history and background of the reaction wheel pendulum and other similar experimental devices. We develop mathematical models of the reaction wheel pendulum in depth, including linear and nonlinear models, and models of the sensors and actuators that are used for feedback control. We treat various aspects of the control problem, from linear control of themotor, to stabilization of the pendulum about an equilibrium configuration using linear control, to the nonlinear control problem of swingup control. We also discuss hybrid and switching control, which is useful for switching between the swingup and balance controllers. We also discuss important practical issues such as friction modeling and friction compensation, quantization of sensor signals, and saturation. This monograph can be used as a supplement for courses in feedback control at the undergraduate level, courses in mechatronics, or courses in linear and nonlinear state space control at the graduate level. It can also be used as a laboratory manual and as a reference for research in nonlinear control.

Book Description
It is hard to imagine tourism without the creative use of seductive, as well as restrictive, imaginaries about peoples and places. These socially shared assemblages are collaboratively produced and consumed by a diverse range of actors around the globe. As a nexus of social practices through which individuals and groups establish places and peoples as credible objects of tourism, “tourism imaginaries” have yet to be fully explored. Presenting innovative conceptual approaches, this volume advances ethnographic research methods and critical scholarship regarding tourism and the imaginaries that drive it. The various authors contribute methodologically as well as conceptually to anthropology’s grasp of the images, forces, and encounters of the contemporary world.

Book Description
Drawing from extended fieldwork in La Réunion, in the Indian Ocean, the author suggests an innovative re-reading of different concepts of magic that emerge in the global cultural economics of tourism. Following the making and unmaking of the tropical island tourism destination of La Réunion, he demonstrates how destinations are transformed into magical pleasure gardens in which human life is cultivated for tourist consumption. Like a gardener would cultivate flowers, local development policy, nature conservation, and museum initiatives dramatise local social life so as to evoke modernist paradigms of time, beauty and nature. Islanders who live in this 'human garden' are thus placed in the ambivalent role of 'human flowers', embodying ideas of authenticity and biblical innocence, but also of history and social life in perpetual creolisation.

Book Description
This work discusses the use of digital computers in the real-time control of dynamic systems using both classical and modern control methods. Two new chapters offer a review of feedback control systems and an overview of digital control systems. MATLAB statements and problems have been more thoroughly and carefully integrated throughout the text to offer students a more complete design picture.

Book Description
Operating at the intersection where new technology meets literature, this collection discovers the relationship among image, sound, and touch in the long nineteenth century. The chapters speak to the special mixed-media properties of literature, while exploring the important interconnections of science, technology, and art at the historical moment when media was being theorized, debated, and scrutinized. Each chapter focuses on a specific visual, acoustic, or haptic dimension of media, while also calling attention to the relationships among the three. Famous works such as Wordsworth's "I wandered lonely as a cloud" and Shelley's Frankenstein are discussed alongside a range of lesser-known literary, scientific, and pornographic writings. Topics include the development of a print culture for the visually impaired; the relationship between photography and narrative; the kaleidoscope and modern urban experience; Christmas gift books; poetry, painting and music as remediated forms; the interface among the piano, telegraph, and typewriter; Ernst Heinrich Weber's model of rationalized tactility; and how the shift from visual to auditory telegraphic instruments amplified anxieties about the place of women in nineteenth-century information networks. Full of surprising insights and connections, the collection offers new impetus for stimulating historical conversations and debates about nineteenth-century media, while also contributing fresh perspectives on new media and (re)mediation today.

''A clear and comprehensive introduction to contemporary philosophy of science.'' -- American Scientist ''The best account of scientific theory now available, one that surely commends itself to every philosopher of science with the slightest interest in metaphysics.'' -- Review of Mathematics ''It should certainly be of interest to those teaching graduate courses in philosophy of science and to scientists wishing to gain a further appreciation of the approach used by philosophers of science.'' -- Science Activities

Book Description
These nine essays, commissioned on the initiative of the Philosophy section of the British Academy, address fundamental questions about time in philosophy, physics, linguistics, and psychology. Are there facts about the future? Could we affect the past? In physics, general relativity and quantum theory give contradictory treatments of time. So in the current search for a theory of quantum gravity, which should give way: general relativity or quantum theory? In linguistics and psychology, how does our language represent time, and how do our minds keep track of it?
