The energy mitigation properties of buckyballs are investigated using molecular dynamics (MD) simulations. A one dimensional buckyball long chain is employed as a unit cell of granular fullerene particles. Two types of buckyballs i.e. C60 and C720 with recoverable and non-recoverable behaviors are chosen respectively. For C60 whose deformation is relatively small, a dissipative contact model is...

In this paper the problem of selecting p out of n available items is discussed, such that their total cost is minimized. We assume that costs are not known exactly, but stem from a set of possible outcomes. Robust recoverable and two-stage models of this selection problem are analyzed. In the two-stage problem, up to p items is chosen in the first stage, and the solution is completed once the s...

SUMMARY Poland has some of Europe's most favorable infrastructure and public support for shale development. The Baltic Basin in northern Poland remains the most prospective region with a relatively simple structural setting. The Podlasie and Lublin basins also have potential but are structurally complex, with closely spaced faults which may limit horizontal shale drilling. A fourth area, the Fo...

A goal for enterprise applications has been to provide “exactly once” execution regardless of system failures. This has classically required “stateless” applications that manage their states explicitly via transactional resource managers. Support for “stateful” applications requires the system to do more to manage state, which has been considered too difficult and costly. The Phoenix/App system...

Abstract: This paper develops an optimizing model for the long-term exploitation of limited natural gas reserves in China. In addition to describing the life cycle characteristics of natural gas production and introducing the inter-temporal allocation theory, this paper builds the optimal exploitation model of natural gas resources within a gas field in the Ordos Basin as an example to analyze ...

Introduction The interpretation of verb meaning hinges in large part on the argument structure of the verb. In a series of experiments, young children have been found to use the number and type of arguments that appear with a verb in order to determine its meaning (e.g., Fisher 1996, 2002; Goldberg 2004; Landau & Gleitman 1985; Lidz, Gleitman & Gleitman 2003; Naigles 1990). For example, when he...
