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.

Nanoindentation and Scratch Resistance Characteristics of AZ31–WC Nanocomposites

Free vibration analysis of initially deflected stiffened plates subjected to uniformly distributed loading with different flexural boundary conditions involving simply supported and clamped ends and zero displacement in-plane boundary conditions has been presented. A domain decomposition technique depending on the number, orientation and location of the stiffeners is employed to ensure sufficient number of computation points around the stiffeners. Geometric non-linearity arising out of large deflection is accounted for by consideration of non-linear strain-displacement relations. Mathematical formulation is based on a variational form of energy principle, and a solution technique, where static analysis serves as the basis for the subsequent dynamic study, is followed. The results are validated with the published results of other researchers. The dynamic behavior has been presented in the form of backbone curves in a dimensionless frequency-amplitude plane. Vibration mode shapes along with contour plots ar...
