Elastic constants from microscopic strain fluctuations
Fluctuations of the instantaneous local Lagrangian strain epsilon(ij)(r,t), measured with respect to a static "reference" lattice, are used to obtain accurate estimates of the elastic constants of model solids from atomistic computer simulations. The measured strains are systematically coarse-grained by averaging them within subsystems (of size L(b)) of a system (of total size L) in the canonic...
متن کاملToppling Manipulation
This paper describes a robotic manipulation primitive called toppling—knocking a part over. We derive the mechanical conditions for toppling, express these as constraints on robot contact locations and motions, and describe an application of toppling to minimalist parts feeding of 3D objects on a conveyor with a 2 joint robot.
متن کاملComment on "Elastic constants from microscopic strain fluctuations".
Sengupta [Phys. Rev. E 61, 1072 (2000)] presented an elegant and simple finite-size scaling method for the calculation of elastic constants and their corresponding correlation lengths, which is suitable for many finite discrete systems considered through simulations or experiments. We take into account a mathematical finite-size effect that was neglected by the authors in order to propose a mor...

OBJECTIVE To assess outcomes of trauma caused by television sets falling onto children. METHODS Retrospective review of medical charts of 183 children aged 7 years and younger hospitalized for injuries caused by falling television sets. Descriptive statistics were applied. DATA SOURCES Phase 2 (1988-1995) and phase 3 (1995-1999) of the National Pediatric Trauma Registry. OUTCOME MEASURES ...
متن کاملYamanouchi Toppling -extended Abstract
We study an extension of the chip-firing game. A given set of admissible moves, called Yamanouchi moves, allows the player to pass from a starting configuration α to a further configuration β. This can be encoded via an action of a certain group, the toppling group, associated with each connected graph. This action gives rise to a generalization of Hall-Littlewood symmetric polynomials and a ne...
