Glass transition and fragility in the simple molecular glassformer CS(2) from CS(2)-S(2)Cl(2) solution studies.

With an interest in finding the fragility for a simple, single component, molecular glassformer, we have determined the dielectric relaxation and glass transition behavior for a series of glasses in the CS(2)-S(2)Cl(2) and CS(2)-toluene systems. Crystallization of CS(2) can be completely avoided down to the composition 20 mol% second component, and the fragility proves almost independent of CS(...

Satellite Communications

We are delighted to bring to you this special issue on satellite communications, which we have prepared as part of the spreading of excellence remit of the satellite communications network of excellence (SatNEx). The SatNEx project, which began in 2004, is funded for five years under the Euro-pean Union's Sixth Framework Programme (FP6) Information Society Technologies (IST) Thematic Area. Led ...

CS 224N Assignment 2 Writeup

A probabilistic context-free grammar (PCFG) maps natural language onto the domain of contextfree grammars by using a constituency grammar. The difference between the deterministic nature of a CFG and the non-determinism of language is resolved by assigning a probability to each rule applied in the parsing of a sentence. In general, PCFG parsing involves a grammar G = (T,N, S,R, P ). T is a set ...

Performance Evaluation and Modeling of MPI Communications on the Meiko CS-2

This paper presents, evaluates and compares the performance of the point-to-point and broadcast communication primitives of the MPI-1 standard library on the Meiko CS-2 parallel machine. Furthermore, a benchmark model of MPI communications is proposed. It is based on the size of messages exchanged and the number of processors involved.
