Explore the challenges presented by modern hard disk drives and learn how to overcome them with Hard Disk Drive: Mechatronics and Control. Beginning with an overview of history, components, operating principles, and industry trends, the authors examine the design and manufacturing challenges. They start with the head positioning servomechanism followed by the design of the actuator servo controller, the critical aspects of spindle motor control, and finally, the servo track writer, a critical technology in hard disk drive manufacturing. The book compares various design approaches for both single- and dual-stage servomechanisms and illustrates the discussion with numerous examples and figures.

The seminal 1989 work of Douglas and Paulsen in the theory of analytic Hilbert modules precipitated a number of major research efforts. This in turn led to some intriguing and valuable results, particularly in the areas of operator theory and functional analysis. With the field now beginning to blossom, the time has come to collect those results under one cover. Written by two of the most active and often-cited researchers in the field, Analytic Hilbert Modules reports on the progress made by the authors and others, including the characteristic space theory, rigidity, the equivalence problem, the Arveson modules, extension theory, and reproducing Hilbert spaces on n-dimensional complex space.

This volume deals with first- and second-order complex equations of hyperbolic and mixed types. The authors investigate in detail general boundary value problems for linear and quasilinear complex equations and present some discontinuous boundary value problems for elliptic complex equations. Mixed complex equations are included in the quasilinear case, and the text considers both boundary value conditions in the general oblique derivative case and multiply-connected domains. The authors also use complex analytical methods to investigate various problems. In particular, they introduce hyperbolic numbers and hyperbolic complex functions to handle hyperbolic complex equations.

Over the last decade the field of spaceborne imaging radar remote sensing has advanced to the point where many new applications have become possible. Radar Remote Sensing Applications in China provides a set of examples of high quality remote sensing work carried out with this leading technology in China, under the auspices of the Institute of Remote Sensing Applications of the Chinese Academy of Sciences, and in collaboration with the USA, European Space Agency, Japan and the former USSR. These examples are discussed, compared with ground truth, and analyzed. This book includes applications, data analysis, algorithm development, modeling and backscatter behavior analysis.
