The Swarthmore College Senseval-3 system
This paper presents the Swarthmore College wordsense disambiguation system which was designed for the 2004 SENSEVAL3 competition. Our system participated in five tasks: the lexical sample tasks in Basque, Catalan, Italian, Romanian, and Spanish. For each task, a suite of supervised algorithms were combined using voting to form the final system.
متن کاملNumerical modeling of magnetohydrodynamic activity in the Swarthmore Spheromak Experiment
Results from a three-dimensional axisymmetric resistive magnetohydrodynamic ~MHD! simulation are compared to experimental data from the Swarthmore Spheromak Experiment ~SSX! @M. R. Brown, Phys. Plasmas 6, 1717 ~1999!#. The MHD simulation is run under conditions and with dimensionless parameters similar to the experiment ~Lundquist number S51000, plasma beta b 50.1). The simulation is shown to r...
متن کاملEnergetic particles and magnetohydrodynamic activity in the Swarthmore Spheromak Experiment
Results from the Swarthmore Spheromak Experiment ~SSX! @M. R. Brown, Phys. Plasmas 6, 1717 ~1999!# indicate that formation and partial merging of two spheromak plasmas can be described well by a magnetohydrodynamic ~MHD! picture in which there is substantial evolution towards force free states within each vessel, while reconnection activity, also described reasonably well by MHD, occurs in the ...
متن کاملLeiden Observatory
In this paper we summarize the main properties of the ENACS (the ESO Nearby Abell Cluster Survey), which was one of the ESO Keypro-grammes carried out in the first half of the 1990's, and we discuss some recent work on the properties of the galaxies in the rich clusters in the ENACS sample. We stress the importance of the ENACS sample as a local , volume-limited sample of rich ACO clusters, whi...
متن کاملModeling Swarthmore spheromak reconnection experiment using hybrid code
A three-dimensional (3D) hybrid-particle model is developed for investigation of magnetic reconnection in the Swarthmore Spheromak Experiment (SSX). In this numerical model, ions are treated as fully kinetic particles, and electrons are treated as a massless fluid. The plasma responds to the electromagnetic fields in a self-consistent manner. The simulation is performed in a cylindrical domain....
