Smooth particle applied mechanics
This book takes readers through all the steps necessary for solving hard problems in continuum mechanics with smooth particle methods. Pedagogical problems clarify the generation of initial conditions, the treatment of boundary conditions, the integration of the equations of motion, and the analysis of the results. Particular attention is paid to the parallel computing necessary for large problems and to the graphic displays, including debugging software, required for the efficient completion of computational projects.

Time reversibility, computer simulation, algorithms, chaos
A small army of physicists, chemists, mathematicians, and engineers has joined forces to attack a classic problem, the “reversibility paradox”, with modern tools. This book describes their work from the perspective of computer simulation, emphasizing the authors' approach to the problem of understanding the compatibility, and even inevitability, of the irreversible second law of thermodynamics with an underlying time-reversible mechanics. Computer simulation has made it possible to probe reversibility from a variety of directions and “chaos theory” or “nonlinear dynamics” has supplied a useful vocabulary and a set of concepts, which allow a fuller explanation of irreversibility than that available to Boltzmann or to Green, Kubo and Onsager. Clear illustration of concepts is emphasized throughout, and reinforced with a glossary of technical terms from the specialized fields which have been combined here to focus on a common theme.

Nonequilibrium Time Reversibility with Maps and Walks
Time-reversible dynamical simulations of nonequilibrium systems exemplify both Loschmidt’s and Zermélo’s paradoxes. That is, computational time-reversible simulations invariably produce solutions consistent with the irreversible Second Law of Thermodynamics (Loschmidt’s) as well as periodic in the time (Zermélo’s, illustrating Poincaré recurrence). Understanding these paradoxical aspects of time-reversible systems is enhanced here by studying the simplest pair of such model systems. The first is time-reversible, but nevertheless dissipative and periodic, the piecewise-linear compressible Baker Map. The fractal properties of that two-dimensional map are mirrored by an even simpler example, the one-dimensional random walk, confined to the unit interval. As a further puzzle the two models yield ambiguities in determining the fractals’ information dimensions. These puzzles, including the classical paradoxes, are reviewed and explored here.

Historical dictionary of postwar Japan
Japan is a mix of the old and the new, traditional and modern, and old fashion and innovative. It has traveled the road to a modern destination without totally losing sight of its traditions and values. Although some in Japan lament the passing of old ways, Japan has held on to a reasonable amount of its traditions and values. This is easier to find in its arts and crafts and its literature and films as well as in its social habits. This book will introduce the broad sweep of people, events, and trends, including the successes and failures, of postwar Japan.
This second edition of Historical Dictionary of Postwar Japan contains a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 500 cross-referenced entries on important personalities, politics, economy, foreign relations, religion, and culture. This book is an excellent resource for students, researchers, and anyone wanting to know more about Japan.

Canonical Temperature Control by Molecular Dynamics
\"Pedagogical derivations for Nosé's dynamics can be developed in two different ways, (i) by starting with a temperature-dependent Hamiltonian in which the variable \\(s\\) scales the time or the mass, or (ii) by requiring that the equations of motion generate the canonical distribution including a Gaussian distribution in the friction coefficient \\(\\zeta\\). Nosé's papers follow the former approach. Because the latter approach is not only constructive and simple, but also can be generalized to other forms of the equations of motion, we illustrate it here. We begin by considering the probability density \\(f(q,p,\\zeta)\\) in an extended phase space which includes \\(\\zeta\\) as well as all pairs of phase variables \\(q\\) and \\(p\\). This density \\(f(q,p,\\zeta)\\) satisfies the conservation of probability (Liouville's Continuity Equation)\" $$(\\partial f/\\partial t) + \\sum (\\partial (\\dot q f)/\\partial q) + \\sum (\\partial (\\dot p f)/\\partial p) + \\sum (\\partial (\\dot \\zeta f)/\\partial \\zeta) = 0 \\ . $$ The multi-authored ``review''\\cite{b1} motivated our quoting the history of Nosé and Nosé-Hoover mechanics, aptly described on page 31 of Bill's 1986 {\\it Molecular Dynamics} book, reproduced above\\cite{b2}.
Paper
Financial and Wildlife Benefits from Crop Tree Release in Pole-Sized Central Hardwood Oak Stands
We simulated growth and development from 481 plots within 21 even-aged, mixed hardwood stands (21‐35 years old) under no treatment and crop tree release (CTR) treatments using the new Central States Variant of the US Forest Service Forest Vegetation Simulator. We assumed a multiobjective approach focused on financial returns (timber production) and wildlife benefits (provision of species that produce hard mast) in crop tree selection. We compared simulation results by age class, site variables, and species groups. All age classes showed returns on investment (ROI) of 7.8% or greater, but stands 26‐35 years old exhibited greater net present values (NPVs). CTR treatments across site, as delineated by aspect and slope positions, also exhibited higher NPVs, with ROI of 8.4% or greater. North and east aspects yielded higher NPVs than south and west aspects within both no-thinning and CTR treatments, and no strong patterns of NPV or ROI emerged among slope positions. CTR treatment delayed financial maturity by 5‐10 years because of increased growth rates and assumed higher quality stems. Desirable overstory mast trees for wildlife habitat, primarily oaks (Quercus spp.) and hickory (Carya spp.), increased in importance value, and mortality of crop trees declined with CTR in all age classes. Simulated CTR treatments indicated potential benefits to enhance financial and wildlife forest values in even-aged, mixed hardwood stands.

Managing the demand-supply chain : value innovations for customer satisfaction
A proven,innovative approach to meeting customer demand Combining an intensive focus on customer/marketplace demands with innovative technology tools developed to execute demand chain planning, Managing the Demand-Supply Chain sets forth a powerful new model for fulfilling customer demand in the best possible way. Four of the world's leading demand chain researchers and implementers demonstrate how select high-tech companies, such as Nokia and Dell, have used the demand chain approach to differentiate their value offerings and delight their customers. The authors introduce three exciting new demand chain tools. \"Demand breakpoint\" identifies the point where value is significantly changed by operations; \"value offering point\" or VOP is the catalyst to demand chain activity; and \"microcosms\" executes demand chain strategies. The authors show managers how to use these tools to implement technology solutions that drive top performance. Special features of Managing the Demand-Supply Chain include: The best thinking from acknowledged leaders in the field An extended case study of Nokia's successful demand chain management implementation Numerous sidebars detailing real-world implementation issues Managing the Demand-Supply Chain is an indispensable resource for managers who want to optimize operational effectiveness, spur innovation, and achieve and sustain excellence in exceeding customer expectations.
