  • Efficiency is a prime concern in syntactic MT decoding, yet significant developments in statistical parsing with respect to asymptotic efficiency haven’t yet been explored in MT. Recently, McDonald et al. (2005b) formalized dependency parsing as a maximum spanning tree (MST) problem, which can be solved in quadratic time relative to the length of the sentence. They show that MST parsing is almost as accurate as cubic-time dependency parsing in the case of English, and that it is more accurate with free word order languages. ...

  • Modern western societies have a paradoxical relationship with risks. On the one hand, there is the utopian quest for a zero-risk society. On the other hand, human activities may increase risks of all kinds, from collaterals of new technologies to global impacts on the planet. The characteristic multiplication of major risks in modern society and its reflexive impact on its development is at the core of the concept of the “Risk Society”

  • Some flow cytometers have the ability to physically separate different sub-populations of interest (cell sorting) depending on their cytometric characteristics (stream-in-air), thus permitting the recovery and purification of cell subsets from a mixed population for further applications (Bergquist et al., 2009; Davey, 2010).

  • AN ASYMPTOTIC RESULT FOR SOME DELAY DIFFERENCE EQUATIONS WITH CONTINUOUS VARIABLE CH. G. PHILOS AND I. K. PURNARAS Received 14 October 2003 We consider a nonhomogeneous linear delay difference equation with continuous variable and establish an asymptotic result for the solutions. Our result is obtained by the use of a positive root with an appropriate property of the so-called characteristic equation of the corresponding homogeneous linear (autonomous) delay difference equation.

  • We also frequently found that even the best corrective lenses did not improve vi- sual acuity of the impaired eye to that of the fellow eye. Through the analysis of these initial cases, an apparently predomi- nant common characteristic of these pa- tients was a work station with papers angled to the right or to the left of themon- itor and keyboard. Other reports revealed the screen was in the frontal position, but was twisted. Still others reported that their habitual work pattern was with their eyes/head twisted.

  • This chapter gives an overview of some properties of the storage occupancy process in a buffer fed with ``fractional Brownian traf®c,'' a Gaussian self-similar process. This model, called here ``fractional Brownian storage,'' is the logically simplest long-range-dependent (LRD) storage system having strictly self-similar input variation. The impact of the self-similarity parameter H can be very clearly illustrated with this model.

  • Abstract This chapter provides an overview of asymptotic results available for parametric estimators in dynamic models. Three cases are treated: stationary (or essentially stationary) weakly dependent data, weakly dependent data containing deterministic trends

  • What is an algorithm? The logical steps to solve a problem. What is a program? Program = Data structures + Algorithms (Niklaus Wirth) The most common tool to define algorithms. • English-like representation of the code required for an algorithm. Pseudocode = English + Code relaxed syntax being instructions using easy to read basic control structures (sequential, conditional, iterative)
