There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

From the Publisher:
This book explores the meta-heuristics approach called tabu search, which is dramatically changing our ability to solve a hostof problems that stretch over the realms of resource planning,telecommunications, VLSI design, financial analysis, scheduling, spaceplanning, energy distribution, molecular engineering, logistics,pattern classification, flexible manufacturing, waste management,mineral exploration, biomedical analysis, environmental conservationand scores of other problems. The major ideas of tabu search arepresented with examples that show their relevance to multipleapplications. Numerous illustrations and diagrams are used to clarifyprinciples that deserve emphasis, and that have not always been wellunderstood or applied. The book's goal is to provide ''hands-on' knowledge and insight alike, rather than to focus exclusively eitheron computational recipes or on abstract themes. This book is designedto be useful and accessible to researchers and practitioners inmanagement science, industrial engineering, economics, and computerscience. It can appropriately be used as a textbook in a masterscourse or in a doctoral seminar. Because of its emphasis on presentingideas through illustrations and diagrams, and on identifyingassociated practical applications, it can also be used as asupplementary text in upper division undergraduate courses. 

Finally, there are many more applications of tabu search than canpossibly be covered in a single book, and new ones are emerging everyday. The book's goal is to provide a grounding in the essential ideasof tabu search that will allow readers to create successfulapplications of their own. Along with the essentialideas,understanding of advanced issues is provided, enabling researchers togo beyond today's developments and create the methods of tomorrow.

Mathematical Handbook for Scientists and Engineers

A highly accurate closed-form expressions for self and mutual frequency-dependent impedance (resistance and inductance per unit length) of a lossy silicon substrate coplanar-strip IC interconnects is developed. The derivation is based on a quasi-stationary full-wave analysis and Fourier integral transformation. The derivation shows the mathematical approximations which are needed in obtaining the desired expressions. As the result, for first time, we presents a new simple, yet surprisingly accurate closed-form expressions which yield accurate estimates of self and mutual frequency-dependent resistance and inductance per unit length of coupled interconnects for a wide range of geometrical and technological parameters. The developed formulas describe the line impedance matrix behaviour over the whole frequency range (i.e. also in the transition region between the skin-effect, slow wave, and dielectric quasi-TEM modes). The results have been compared with reported data obtained by the modified quasi-static spectral domain approach and new CAD-oriented equivalent-circuit model procedure.

Analytic model for self and mutual frequency-dependent impedance of multiconductor interconnects on lossy silicon substrates

On the frequency dependent line admittance of VLSI interconnect lines on silicon based semiconductor substrates

In this paper we report an on-wafer waveguide tuner set-up and demonstrate its use in the design of an off-chip cavity based oscillator MMIC for 60 GHz. Measured oscillators discussed in the paper operated at frequencies of 59.3579 GHz, 59.3581 and 60.4495GHz with phase noise levels at 1MHz carrier offset of −122.68 dBcHz−1, −123.11 dBcHz−1 and −120.75 dBcHz−1 respectively. To the authors' knowledge, these are the lowest values reported to date in this frequency range. The simulation approach used is based on a small-signal description and agrees very well with measured oscillation frequencies.
