This paper presents the results of a simulation study of cache coherency issues in parallel implementations of functional programming languages. Parallel graph reduction uses a heap shared between processors for all synchronisation and communication. We show that a high degree of spatial locality is often present and that the rate of synchronisation is much greater than for imperative programs....

The goal of cross-show diarization is to index speech segments of speakers from a set of shows, with the particular challenge that reappearing speakers across shows have to be labeled with the same speaker identity. In this paper, we introduce three cross-show diarization systems namely Global-BIC-Seg, Global-BIC-Cluster, and Incremental. We compared the three systems on a set of 46 English sci...

The idea of obtaining the seismic trace representing the impulse response at one receiver due to a source at another receiver has discussed by many authors. Jon Claerbout (see e.g. Rickett and Claerbout, 1996; Claerbout, web) introduced the concept to seismology. It has been investigated in the laboratory by Lobkis and Weaver (2001), observed in seismic data by Campillio and Paul (2003), and in...

Some bugs, among the millions that exist, are similar to each other. When fixing a bug, a programmer tends to search for similar bugs that have been reported and resolved in the past. A fix for a similar bug can help him understand his bug, or even directly fix his bug. Studying bugs with similar symptoms, programmers may determine how to detect or resolve them. Existing work has focused on ana...

High bandwidth network traffic traces are needed to understand the behavior of high speed networks (such as the Internet backbone). However, the implementation of a mechanism to collect such traces is difficult in practice. In the absence of real traces, tools to generate high bandwidth traces would aid the study of high speed network behavior. We describe three methods of generating high bandw...

The objective evaluation of 2D-shape estimation results for moving objects in a video sequence is still an open problem. First approaches in the literature evaluate the spatial accuracy and the temporal coherency of the estimated 2D object shape. Thereby, it is not distinguished between several estimation errors located around the object contour and a few, but larger, estimation errors. Both ca...

A new type of backbone robot is presented in this paper. The core idea is to use a cross shape mechanism with the principle of functioning of the scissors linkages, known as a pantograph. Although this continuum arm acts quite similar to tendon-driven robot, this manipulator does not include any tendon in its structure. This design does not suffer from the weaknesses of the continuum design suc...

It was usually believed that the formation of intragranular ?-carbide in ?-austenite attributed to spinodal decomposition followed by ordering reaction. In this work, near-atomic scale characterization an austenite-based Fe-20Mn-9Al-3Cr-1.2C (wt. %) low-density steel, using (high-resolution) scanning transmission electron microscopy and atomic probe tomography, reveals initially-formed ?-carbid...
