Data center networks leverage multiple parallel paths connecting end host pairs to offer high bisection bandwidth for cluster computing applications. However, state of the art distributed multi-pathing protocols such as Equal Cost Multipath (ECMP) use static flow-to-link assignment, which is loadoblivious. They may cause bandwidth loss due to flow collisions on a same link. Recently proposed ce...

This study differentiates between probability models that lead to gardenpathing and those that fail to do so in an incremental dependency parser. Models that take into account intermediate parserstates and part-of-speech pairs correctly reflect human preferences in three wellknown cases: Main Verb vs. Reduced Relative ambiguities, Prepositional Phrase Attachment and Subject-Object ambiguities. ...

Common-azimuth migration (CAM) is a 3-D prestack depth migration technique based on the wave equation (Biondi and Palacharla, 1996). It exploits the intrinsic narrow-azimuth nature of marine data to reduce its dimensionality and thus manages to cut the computational cost of 3-D imaging significantly enough to compete with Kirchhoff methods. Based on a recursive extrapolation of the recorded wav...

3-D prestack common-azimuth depth migration (CAM) has strong potential for accurately imaging complex media and correctly handling multi-pathing. Here, we apply the technique to a North Sea dataset recorded over a salt dome region. The results obtained demonstrate the suitability of the method for complex media, and illustrate important differences with Kirchhoff methods. A detailed analysis of...

We present a painterly rendering technique that emphasizes smooth line flows to describe important shapes in the image, as well as contributing in an essential part to the final stylistic artwork. Our method uses the smoothed edge tangent flow (ETF) [20] for stroke pathing, and provides an artist-friendly way to control the general look and feel of the image using familiar brush stroke properti...

Inspired by the seminal paper on ”Model Transformations? Transformation Models!” [1] we will have a fresh look on the evolution of model evolution. Model evolution is more and more seen as part of change management in general with change as first class principle in the whole software product lifecycle. Thus, a descriptive notion of evolution in terms of evolution models is necessary. In this ta...

This paper presents modifications to a standard probabilistic context-free grammar that enable a predictive parser to avoid garden pathing without resorting to any ad-hoc heuristic repair. The resulting parser is shown to apply efficiently to both newspaper text and telephone conversations with complete coverage and excellent accuracy. The distribution over trees is peaked enough to allow the p...

It has been hypothesized that much of the crustal deformation attributed to the Laramide orogeny of the southwest North American Cordillera was caused by dynamic effects induced by the flat subduction of a large oceanic plateau that was embedded within the Farallon plate. Previous studies have identified within the North American mantle a seismic velocity anomaly that plausibly represents the r...

[1] New waveform tomographic evidence displays a narrow plume‐like feature emitting from the top of the large African low‐velocity structure in the lower mantle. A detailed SKS wavefield is assembled for a segment along the structure’s southern edge by combining multiple events recorded by a seismic array in the Kaapvaal region of southern Africa. With a new processing technique that emphases m...
