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.

Electroless nickel, alloy, composite and nano coatings – A critical review

Determination of Oxygen and Nitrogen in Ag Nanoparticles: Role of Surfactants

Tribological behaviour of Al–SiC metal matrix composites prepared using two different fabrication techniques, viz sand cast and squeeze cast techniques are studied in a multi- tribotester (TR-25, DUCOM, India) under dry sliding conditions and ambient atmosphere for varying volume fraction of reinforcement, applied load and sliding speed Friction increases with increase in applied load and sliding speed and volume fraction of reinforcement Wear test results show increased wear rates at higher load and speed, while increase in SiC volume fraction yields decrease in wear rate Corrosion study conducted in 35 % NaCl solution shows that squeeze cast composites have better corrosion resistance than sand cast composites Vickers’s microhardness test shows improved hardness properties for squeeze cast composites compared to sand cast ones The microstructure study of wear tracks reveals domination of abrasive wear with minor traces of adhesive wear

Tribological Performance Optimization of Electroless Nickel Coatings Under Lubricated Condition

This paper deals with abrasive wear behavior of two different composite materials namely Al-TiB2 and Al-TiB2-nano-graphite At the time of fabrication, ultrasonic vibration is used along with mecha

Abrasive wear behavior of Al-TiB2 and Al-TiB2-nano-graphite metal matrix composites:

The aim of this paper is to develop a simulation model of large deformation problems following a semi-analytical method, incorporating the complications of geometric and material non-linearity in the formulation. The solution algorithm is based on the method of energy principle in structural mechanics, as applicable for conservative systems. A one-dimensional solid circular bar problem has been solved in post-elastic range assuming linear elastic, linear strain hardening material behaviour. Type of loading includes uniform uniaxial loading and gravity loading due to body force, whereas the geometry of the bar is considered to be non-uniformly taper. Results are validated successfully with benchmark solution and some new results have also been reported. The location of initiation of elasto-plastic front and its growth are found to be functions of geometry of the bar and loading conditions. Some indicative results have been presented for static and dynamic problems and the solution methodology developed for one-dimension has been extended to the elasto-plastic analysis of two-dimensional strain field problems of a rotating disk.
