Numerical simulations of unsteady three-dimensional compressible flow problems require the solution of large, sparse, nonlinear systems of equations arising from the discretization of Euler or Navier-Stokes equations on unstructured, possibly dynamic, meshes. In this paper we study a highly parallel, scalable, and robust nonlinear iterative method based on the Defect Correction method (DeC), th...

Although the nature of epilepsy and headache association has not been full understand, during the past 100 years several potential mechanisms have been proposed to explain the link between these two conditions [1]. To get a definitive international consensus on the crossover between headache and epilepsy, many authors have spent endless efforts to reach an agreement on the various aspects of th...

In this paper we present a framework for the fusion of radar and image information. In the case considered here we combine information from multiple closerange radars to one fused radar measurement using the overlap region of the individual radars. This step is performed automatically using a feature based matching technique. Additionally, we use multiple 2D/3D cameras that generate (color) ima...

Spectral synthesis techniques often use the OverLap-Add method. But in the case of noise synthesis, both experiments and theory show that this method introduces intensity fluctuations which imply audible artifacts. We propose here new methods to avoid these variations. The first one consists in multiplying the resulting signal by another weighting window to compensate dynamic fluctuations. The ...

We present faster overlap tests between spheres and either axis-aligned or oriented boxes. By utilizing quick rejection tests, faster execution times are observed compared to previous techniques. In addition, we present alternative vectorized overlap tests, which are compared to the sequential algorithms. Source code is available online.

In this our first participation in TREC we have focused on the passage task of the question answering track. The main aim of our participation was to test the impact of various types of linguistic information in a simple question answering system. In particular, we have tested various combinations of word overlap, grammatical relations overlap, and overlap of minimal logical forms in the final ...

This year we evaluated our supervised answer validation method at both, the Spanish Answer Validation Exercise (AVE) and the Spanish Question Answering Main Task. This paper describes and analyzes our evaluation results from both tracks. In resume, the F-measure of the proposed method outperformed the baseline result of the AVE 2008 task by more than 100%, and enhanced the performance of our qu...

In this talk I concentrate on two topics closely related to the understanding of the energy and the system size dependence of the elliptic flow: determination of the elliptic flow (v2) “free” from the effects of non-flow and flow fluctuations, and the role of fluctuations in the initial eccentricity of the overlap region. I introduce a new approach for the analysis of the distribution in flow v...

Tissue growth can be modeled in two dimension by only using circular granular cells, which can grow and produce child. Linear spring-dashpot model is used to bind the cells with a cutoff interaction range of 1.1 times sum of radii of interacted cells. Simulation steps must be divided into explicit and implicit ones due to cell growing stage and cell position rearrangement. This division is aime...
