  • The ability to create intelligent machines has intrigued humans since ancient times, and today with the advent of the computer and 50 years of research into AI programming techniques, the dream of smart machines is becoming a reality. Researchers are creating systems, which can mimic human beings. Accurate mathematical models neither always exist nor can they be derived for all complex environments because the domain may not be thoroughly understood. The solution consists of constructing rules that apply when input values lie within certain designer-defined categories....

  • This Second Edition of the go-to reference combines the classical analysis and modern applications of applied mathematics for chemical engineers. The book introduces traditional techniques for solving ordinary differential equations (ODEs), adding new material on approximate solution methods such as perturbation techniques and elementary numerical solutions. It also includes analytical methods to deal with important classes of finite-difference equations. The last half discusses numerical solution techniques and partial differential equations (PDEs). The read...

  • The new monograph ‘‘Mathematical Modeling in Mechanics of Granular Mate- rials’’ written by Oxana & Vladimir Sadovskii is based on a previous Russian version published in 2008. The Russian version was significantly revised and extended. The References were updated with respect to the readers not being familiar with the Russian language. Instead of eight chapters of the Russian ori- ginal version there are now ten chapters—a new chapter devoted to continua with independent rotational degrees of freedom is added....

  • At present, thickness measurement of materials based on effect of backscattering gamma-ray has been widely used in industry in our country. The report presented research in measuring thickness of some materials such as paper, plastic, aluminum and steel with using the dedicated system of MYO-101, having scintillation detector of YAP(Ce) and gamma-ray of 60 keV of Am-241 source, by Monte-Carlo simulation using the code of MCNP. The simulation was checked by experimental measurements.

  • Scoring Extended- and Short-Response Items Extended- and short-response items are evaluated according to an established scoring scale, called a rubric, developed from a combination of expectations and a sample of actual student responses. Such rubrics must be particularized by expected work and further developed by examples of student work in developing a guide for scorers. Illinois educators play a substantial role in developing these guides used for the scoring of the short- and extended-response items.

  • This is the third volume in the series “Tutorial in Mathematical Biosciences”. These lectures are based on material which was presented in tutorials or developed by visitors and postdoctoral fellows of the Mathematical Biosciences Institute (MBI), at The Ohio State University. The aim of this series is to introduce graduate students and researchers with just a little background in either mathematics or biology to mathematical modeling of biological processes. The first volume was devoted to mathematical neuroscience, which was the focus of the MBI program in 2002–2003.

  • This, the Twenty-Seventh Yearbook, and its companion volume, the Twenty-Eighth Yearbook, have been long in the making. Into these two books have gone the combined contributions, suggestions, and criticisms of innumerable individuals, committees, and subcommittees. The academically talented student in mathematics has always been with us, and most teachers have always attempted to provide for his special needs in one way or another. The principal purpose of this year-book is to give teachers one more resource in order to provide for the talented more efficiently and more quickly. ...

  • With its origins in the theories of continuous distributions of dislocations and of metal plasticity, inhomogeneity theory is a rich and vibrant field of research. The recognition of the important role played by configurational or material forces in phenomena such as growth and remodelling is perhaps its greatest present-day impetus. While some excellent comprehensive works approaching the subject from different angles have been published, the objective of this monograph is to present a point of view that emphasizes the differentialgeometric aspects of inhomogeneity theory.

  • Thermal expansion property of three-phase fiber composite material reinforced by spherical particles is one of important properties of this material. In this paper, we would like to propose a way in order to determine thermal expansion coefficients of three-phase composite reinferced by fibres and spherical particles. Keywords: thermal expansion coefficients, three-phase composite material, aligned fibres, spherical particles, effective matrix phase.

  • Today, nano composite material is being studied and widely used for defence security and economic development. Keeping researching on the mechanic of three-phases nano composite in which two-phases is grains of pad and the structure of one-phase in reinforced two-phases is a nano structure, basing on consideration for interaction of the polyme matrix and grains of padding, we have defined engineering constants of the three-phases polyme composite nano material.

  • The stability problem of thin triangular plates by the small elastoplastic deformation theory, was studied in [3]. Basing on the theory of elastoplastic processes, this problem again has been investigated in [4] with incompressible material. In this paper we continue to study the mentioned problem with compressible material. The relation for determining critical forces is established. In particular the explicit expression of the critical force for the linear hardening material is found. Some numerical calculations have been given and discussed. ...

  • (BQ) In the present study, the temperature distribution on the surface of workpiece and tool during a single discharge in the electrical discharge machining process has been simulated using ABAQUS code finite element software. The temperature dependency of material properties and the expanding of plasma channel radius with time have been employed in the simulation stage. The profile of temperature distribution has been utilized to calculate the dimensions of discharge crater.
