In this paper, we focus on the task of generating elliptic sentences. We extract from the data provided by the Surface Realisation (SR) Task (Belz et al., 2011) 2398 input whose corresponding output sentence contain an ellipsis. We show that 9% of the data contains an ellipsis and that both coverage and BLEU score markedly decrease for elliptic input (from 82.3% coverage for non-elliptic senten...

An enhanced grid system for the Orbiter was built by integrating CAD definitions from several sources and then generating the surface and volume grids. The new grid system contains geometric components not modelled previously plus significant enhancements on geometry that has been modelled in the old grid system. The new Orbiter grids were then integrated with new grids for the rest of the laun...

The grid codes now require doubly fed induction generator (DFIG) wind turbines having the “low voltage ride-through (LVRT)” capability. However, a traditional DFIG with a partially rated back-to-back converter has inherent difficulties to ride through the grid faults, especially for the unbalanced grid faults. Modifications to the traditional DFIG configuration for ride-through have become nece...

This paper describes fuzzy logic control of induction generator speed in wind turbine application. The aim of fuzzy controller is to establishe maximum power delivery to the grid from available wind power. Fully-controlled wind turbine which consists of induction generator and back-to-back converter is under estimate. This configuration has full control over the electrical torque, full control ...

This paper presents the dynamic model and control schemes of a wind turbine Generator system equipped with permanent magnet synchronous generator (PMSG).Along with the PMSG, , wind turbine have been modeled and the equations that explain their behaviour have been introduced. The PMSG model is established in the dq–synchronous rotating reference frame. The concept of the Maximum Power Point Trac...

In this paper, two promising multi-megawatt wind turbines equipped with a doubly-fed induction generator-based partial-scale and a permanent magnet synchronous generator-based full-scale two-level power converter are designed and compared. Simulations of the two configurations with respect to loss distribution and junction temperature variation for the power device over the entire wind speed ra...

Lattice tests are quality measures for assessing the intrinsic structure of pseudorandom number generators. Recently a new lattice test has been introduced by Niederreiter and Winterhof. In this paper, we present a general inequality that is satisfied by any periodic sequence. Then, we analyze the behavior of the linear congruential generators on elliptic curves (abbr. EC-LCG) under this new la...
