Экономические вопросы эксплуатации и технического развития железных дорог
Определение оптимальных сроков службы грузовых вагонов имеет большое народнохозяйственное значение, так как, располагая данными об их величине, можно более обоснованно планировать процесс обновления вагонного парка, заявки на поставку грузовых вагонов. Объем их выбытия, долю парка за счет поставок новых вагонов, а в конечном итоге - планировать по пятилетним периодам капиталовложения в развитие всего парка грузовых вагонов и конкретного типа вагонов.

Mathematics for the Physical Sciences
The book begins with a thorough introduction to complex analysis, which is then used to understand the properties of ordinary differential equations and their solutions. The latter are obtained in both series and integral representations. Integral transforms are introduced, providing an opportunity to complement complex analysis with techniques that flow from an algebraic approach. This moves naturally into a discussion of eigenvalue and boundary vale problems. A thorough discussion of multi-dimensional boundary value problems then introduces the reader to the fundamental partial differential equations and "special functions" of mathematical physics. Moving to non-homogeneous boundary value problems the reader is presented with an analysis of Green's functions from both analytical and algebraic points of view. This leads to a concluding chapter on integral equations.

Mathematics in the Age of the Turing Machine
Mathematical models and algorithms rule the quantitative world. Without applied mathematics, we would be bereft of Shor’s factorization algorithm for quantum com-puters, Yang-Mills theories of strong interactions in physics, invisibility cloaks, Radon transforms for medical imaging, models of epidemiology, risk analysis in insurance, stochastic pricing models of financial derivatives, RSA encryption of sensitive data, Navier-Stokes modeling of fluids, and models of climate change. Without it, entire fields of engineering from Control Engineering to Operations Research would close their doors. The early icon of mathematical computing, Von Neumann, divided his final years between meteorology and hydrogen bomb calculations. Today, applications fuel the economy: in 2011 rankings, the first five of the “10 best jobs” are math or computer related: software engineer, mathematician, actuary, statistician, and computer systems analys.

Matrix Analysis and Algorithms
The book contains an introduction to matrix analysis, and to the basic algorithms of numerical linear algebra. Further results can be found in many text books. The book of Horn and Johnson is an excellent reference for theoretical results about matrix analysis. The subject of linear algebra, and matrix analysis in particular, is treated in an original and illuminating fashion in [Lax97]. For a general introduction to the subject of numerical linear algebra we recommend the book by Trefethen and Bau; more theoretical treatments of the subject can be found in Demmel, Golub and Van Loan and in Stoer and Bulirsch. Higham's book contains a wealth of information about stability and the effect of rounding errors in numerical algorithms; it is this source that we used for almost all theorems we state concerning backward error analysis. The book of Saad covers the subject of iterative methods for linear systems. The symmetric eigenvalue problem is analysed in Parlett.

Metamath: A Computer Language for Pure Mathematics
Metamath is a computer language and an associated computer program for archiving, verifying, and studying mathematical proofs at a very detailed level. The Metamath language incorporates no mathematics per se but treats all mathematical statements as mere sequences of symbols. You provide Metamath with certain special sequences (axioms) that tell it what rules of inference are allowed. Metamath is not limited to any specific field of mathematics. The Metamath language is simple and robust, with an almost total absence of hard-wired syntax, and I believe that it provides about the simplest possible framework that allows essentially all of mathematics to be expressed with absolute rigor.

Neutrality and Many-Valued Logics
This book written by A. Schumann & F. Smarandache is devoted to advances of non-Archimedean multiple-validity idea and its applications to logical reasoning. Leibnitz was the first who proposed Archimedes’ axiom to be rejected. He postulated infinitesimals (infinitely small numbers) of the unit interval [0, 1] which are larger than zero. In this book, we consider various many-valued logics: standard, linear, hy-perbolic, parabolic, non-Archimedean, p-adic, interval, neutrosophic, etc. We survey also results which show the tree different proof-theoretic frameworks for many-valued logics, e.g. frameworks of the following deductive calculi: Hilbert’s style, sequent, and hypersequent.

Notes on Differential Equations
These Notes on Differential Equations are an introduction and invitation. The focus is on. Important models. Calculus in applied contexts. I may point out that the title is not Solving Differential Equations; we derive them, discuss them, review calculus background for them, apply them, sketch and compute them, and also solve them and interpret the solutions. This breadth is new to many students. The notes, available for many years on my web page, have evolved from lectures I have given while teaching the Engineering Mathematics courses at Cornell University. They could be used for an introductory unified course on ordinary and partial differential equations. There is minimal manipulation and a lot of emphasis on the teaching of concepts by example.

Metal Forming
This book is designed to help the engineer understand the principles of metal forming and analyze forming problems – both the mechanics of forming processes and how the properties of metals interact with the processes. The first third of the book is devoted to fundamentals of mechanics and materials; the middle to analyses of bulk forming processes such as drawing, extrusion, and rolling; and the last third covers sheet forming processes.
