PPQ : a pregroup parser using majority composition
Pregroup grammars are a mathematical formalism in the spirit of categorial grammars. They are close to logical formalism like Lambek calculus but have a polynomial parsing algorithm. The paper presents a parser based on pregroup grammar that uses a tabular approach based on majority partial composition.
متن کاملCollecting relations for the Number Field Sieve in GF ppq
In order to assess the security of cryptosystems based on the discrete logarithm problem in non-prime finite fields, as are the torus-based or pairing-based ones, we investigate thoroughly the case in Fp6 with the Number Field Sieve. We provide new insights, improvements, and comparisons between different methods to select polynomials intended for a sieve in dimension 3 using a special-q strate...
متن کاملTrajectory ❖ ❖ ❖
The trajectory of the impacting asteroid is another issue of considerable debate and still unresolved. Historically, circular plan views of impact craters confounded many investigators who assumed a circular crater requires a vertical impact. They wondered why more craters are not elliptical. Gilbert and Barringer both realized that 45° impacts are the most probable trajectories for meteoritic ...
متن کاملTrajectory engine: a backend for trajectory sampling
The management of communication networks increasingly requires detailed knowledge of network usage, acquired by direct measurement. We report on the design and implementation of a backend system for Trajectory Sampling, a method for consistent sampling of packets across a network domain. This Trajectory Engine collects trajectory samples and stores them after appropriate preprocessing. It provi...
متن کاملSELECTIVE R.T.L.P.C.V.D. OF TUNGSTEN BY SILANE REDUCTION ON PATTERNED PPQ/Si WAFERS
Organic dielectrics are an attractive alternative to silicon oxide commonly used in multilevel metallization schemes. In this work, tungsten films are selectively deposited on substrates covered by patterned organic dielectric through a Rapid Thermal Low Pressure Chemical Vapor Deposition system by using the WF,-SiH4-H, gas phase. In the entire range of parameters, a-W is the only phase obtaine...
