The addition of a deterministic permutation parser can provide valuable hierarchical information to a phrase-based statistical machine translation (PBSMT) system. Permutation parsers have been used to implement hierarchical re-ordering models (Galley and Manning, 2008) and to enforce inversion transduction grammar (ITG) constraints (Feng et al., 2010). We present a number of theoretical results...

Domain wall (DW) based logic and memory devices require precise control and manipulation of DW in nanowire conduits. The topological defects of Transverse DWs (TDW) are of paramount importance as regards to the deterministic pinning and movement of DW within complex networks of conduits. In-situ control of the DW topological defects in nanowire conduits may pave the way for novel DW logic appli...

We address the problem of estimating the source-destination (SD) traffic matrix of a VPN from measurements of aggregated traffic along all access links. We derive two different estimators by formulating the estimation of the SD-traffic matrix in the form of both deterministic and stochastic optimization problems. One estimator yields the estimates from a snapshot of the access link loads; the o...

This paper presents a new method that combines quasi-Monte Carlo quadrature with importance sampling to solve the general rendering equation efficiently. Since classical importance sampling has been proposed for Monte-Carlo integration, first an appropriate formulation is elaborated for deterministic sample sets used in quasi-Monte Carlo methods. This formulation is based on integration by vari...

the benefits of textual input enhancement in the acquisition of linguistic forms have produced mixed results in sla literature. the present study investigates the effects of textual enhancement on adult foreign language intake of two english linguistic forms-subjunctive mood and inversion structures-to explore the role of the type of linguistic items in input enhancement studies. it also invest...

Let X be a regular linear diffusion whose state space is an open interval E ⊆ R. We consider a diffusion X∗ which probability law is obtained as a Doob htransform of the law of X, where h is a positive harmonic function for the infinitesimal generator of X on E. This is the dual of X with respect to h(x)m(dx) where m(dx) is the speed measure of X. Examples include the case where X∗ is X conditi...

A probabilistic asynchronous cellular automaton described previously [Seybold, Kier, and Cheng, J. Chem. Info. Comput. Sci. 1997, 37, 386-391] has been applied to the description of molecular excited-state dynamics. The model simulates in a visual, time-dependent fashion the variations in groundand excited-state populations that occur under stipulated probabilistic transition rules. Both pulse ...

X-ray tomography at the level of single biological cells is possible in a low-dose regime, based on full-field holographic recordings, with phase contrast originating from free-space wave propagation. Building upon recent progress in cellular imaging based on the illumination by quasi-point sources provided by X-ray waveguides, here this approach is extended in several ways. First, the phase-re...

Inverse execution is a non-deterministic process of discovering the inputs to a program starting from its output. This paper deals with the inverse execution of Constraint Handling Rules (CHR). First a simple inversion technique is proposed, which produces a reverse program consisting of rules with exchanged left and right hand sides. The limitations of this method are presented and reveal the ...

This paper shows the suitability of High Resolution (HR) TerraSAR-X data for monitoring urban areas by means of feature extraction algorithms able to exploit the new information content provided by HR Synthetic Aperture Radar (SAR) images. The approach we follow is deterministic and model-based, meaning that the building feature extraction is based on the direct inversion of the electromagnetic...
