This paper describes the German-English translation system developed by the ARK research group at Carnegie Mellon University for the Sixth Workshop on Machine Translation (WMT11). We present the results of several modeling and training improvements to our core hierarchical phrase-based translation system, including: feature engineering to improve modeling of the derivation structure of translat...

The past year was a momentous one for India. The country navigated through the shoals of an unprecedented global financial crisis with only modest negative impact, and successfully continued the world’s largest exercise in democracy. The 15th general election in April-May 2009 saw the venerable Congress Party return to power with a large mandate. On the external front, although ties between Ind...

Let the edges of a graph G be coloured so that no colour is used more than k times. We refer to this as a k-bounded colouring. We say that a subset of the edges of G is multicoloured if each edge is of a different colour. We say that the colouring is H-good, if a multicoloured Hamilton cycle exists i.e., one with a multicoloured edge-set. Let ARk = {G : every k-bounded colouring of G is H-good}...

We present a power spectrum analysis of the long ASCA observation of Ark 564 in June/July 2001. The observed power spectrum covers a frequency range of ∼ 3.5 decades. We detect a high frequency break at ∼ 2 × 10 −3 Hz. The power spectrum has an rms of ∼ 30% and a slope of ∼ −1 and ∼ −2 below and above the break frequency. When combined with the results from a long RXTE observation (Pounds et al...

Abstra t Let the edges of a graph G be oloured so that no olour is used more than k times. We refer to this as a k-bounded olouring. We say that a subset of the edges of G is multi oloured if ea h edge is of a di erent olour. We say that the olouring is H-good, if a multi oloured Hamilton y le exists i.e., one with a multi oloured edgeset. Let ARk = fG : every k-bounded olouring of G is H-goodg...

Between the Restoration of Charles II in 1660 and the death of Queen Anne in 1714, England experienced a "golden age of political arithmetic" in which the work of William Petty and John Graunt, Gregory King and Charles Davenant was greatly admired. The traditional chronology of modern statistics has either ignored this period altogether or dismissed it as a false start and emphasized the signif...

Grapheme-color synesthetes experience colors when they see printed letters of the alphabet. Currently, we tested four "projector" synesthetes, whose colors evoked by graphemes have sensory support or quale and appear to be restricted spatially to the letters like real colors. We use three different kinds of puzzle pictures that contained hidden letters, which require 30 s or more for nonsynesth...

Musculoskeletal disorders (MSDs) are amongst the most common work-related problems throughout the world and India is no exception. MSD risk factors can be an appropriate base for planning and implementing ergonomics intervention programs in the workplace. The present study is focused on identifying the occupational health and safety risks of workers in Indian sawmills. The workers in saw mills ...

We present spatial, temporal and spectral analyses of ROSAT Position Sensitive Pro-Ark 564 is a powerful narrow-line Seyfert 1 with strong Fe ii emission. Several similar narrow-line Seyfert 1 galaxies have recently been found to have remarkably steep soft X-ray continua as well as rapid X-ray variability. We nd that Ark 564 also has a very steep ((> 3) 0.1{2.5 keV spectrum and varies by 20 per...
