  • We have developed a new formulation for fast calculation of far-field force of fast multipole method (FMM)in molecular dynamics simulations. FMM is a linear algorithm to calculate force for molecular dynamics simulations. GRAPE is a special-purpose computer dedicated to Coulombic force calculation. It runs 100-1000 times faster than normal computer at the same price. However FMM cannot be implemented directly on GRAPE. We have succeeded to implement FMM on GRAPE and developed a new formulation for far-field force calculation. ...

  • This monograph documents recent (2005–2008) RAND Corporation research on combat air force aircrew management problems resulting from the competing goals of producing sufficient experienced combat pilots and operating within the constraints of force structure reductions. The monograph summarizes the supply-and-demand problems the fighter force has faced over the past decade, summarizes the decisions made in an attempt to solve them, and describes the RAND dynamic simulation model used to help t

  • In practice, however, earthquakes generate stronger ground motion than Level 1 but not exceeding Level 2 can occur in service life of a structure. In current seismic design, consideration was not given directly to changes in activities and risks to the seismic motion through time and the importance of adopting effective methods of repair and reinforcement. These factors can not be implemented fully into account by simply checking the elastic limit or reparability limits or structural collapse of a Level 1 or 2 earthquake motion forces based on current seismic design....

  • In general, it is the BEV (not the )V) that describes the VTV crash severities in a complete manner. Only in the fixed barrier test condition or when the stiffness ratio equals the mass ratio, will BEV (or crash severity index) be the same as )V (or crash momentum index). This relationship can be proved by simply making Rm = Rk and substituting into Eq. (7.52). Then BEV1/Vclose = )V/Vclose = 1/(1+Rm). 7.6.3 Crash Severity Assessment by a Power Curve Model This section presents a model with power curve force deflection, as shown in Fig. 7.28. The model is used...

  • When the field of microfluidics emerged in the early 1990s, it was primarily focused on the development of analytical microdevices. Since then, microfluidics has expanded its influence into virtually every branch of science and engineering. There are many driving forces behind this explosive growth. To name a few: • Scaling properties afforded by miniaturization are desirable for many applications. For example, enhanced mass transfer and heat dissipation enable faster chemical separations without sacrificing separation performance....

  • Mechanics is the study of force, deformation, and motion, and the relations between them. We care about forces because we want to know how hard to push something to move it or whether it will break when we push on it for other reasons. We care about deformation and motion because we want things to move or not move in certain ways. Towards these ends we are confronted with this general mechanics problem:

  • This book is an introduction to game theory from a mathematical perspective. It is intended to be a first course for undergraduate students of mathematics, but I also hope that it will contain something of interest to advanced students or researchers in biology and economics who often encounter the basics of game theory informally via relevant applications. In view of the intended audience, the examples used in this book are generally abstract problems so that the reader is not forced to learn a great deal of a subject – either biology or economics – that may be unfamiliar.
