We develop a new method for estimating and removing the spectrum of the sky from deep spectroscopic observations. Our method does not rely on simultaneous measurement of the sky spectrum with the object spectrum. The technique is based on the iterative subtraction of continuum estimates and eigenvector sky models derived from singular value decompositions of sky spectra and sky spectra residual...

The management of grid is differing from that of individual system and current Internet. A novel model on network management--Dynamically Constructed Network Management (DCNM) is proposed. Maybe it could give a good suggestion to management on grid. The network services and applications are treated as “soft equipment” managed by the NMS thus all the resources in the network can be managed under...

The effect of the volume flow rate of the heat transfer fluid (air) on the thermal parameters of the solar air collector with a single air pass without using fins under the absorbing plate have been investigated experimentally and theoretically. We use a new design of solar air collector which aims to optimize these parameters in the region cited above. Our solar air collector was realized at t...

We present optical spectroscopy of three brown dwarf candidates identified in the first 1% of the DENIS sky survey. Low resolution spectra from 6430–9150Å show these objects to have similar spectra to the brown dwarf candidate GD 165B. High resolution spectroscopy shows that one of the objects – DENIS-P J1228.2-1547 – has a strong 2.3±0.05Å equivalent width absorption line of Li I 6708Å, and is...

To maximize the number of transients discovered on the sky, should skymonitoring projects stare at one location or continually jump from location to location, tiling the sky? If tiling is preferred, what cadence maximizes the discovery rate? As sky monitoring is a growing part of astronomical observing, utilized to find such phenomena as supernovae, microlensing, and planet transits, well thoug...

We present a novel approach to pose-invariant face recognition that handles continuous pose variations, is not database-specific, and achieves high accuracy without any manual intervention. Our method uses multidimensional Gaussian process regression to learn a nonlinear mapping function from the 2D shapes of faces at any non-frontal pose to the corresponding 2D frontal face shapes. We use this...

Arthritis is a group of diseases, the handling of which by the medical profession is no cause for pride. The approach to the problem of arthritis by the profession has been based upon premises which are definitely false and this monograph by two of the most distinguished authorities in their respective fields is an heroic attempt to put the treatment of chronic arthritis on a rational basis. It...

A homogeneous set of new measurements of nearly all (995 out of 1007) objects from the Strasbourg-ESO Catalogue of Galactic Planetary Nebulae or in the first supplement of this catalogue in the area covered by the DENIS survey (δ < +2) is given here. A list of 24 new and 27 wrong crossidentifications with sources in the IRAS PSC catalogue and some confusion in the literature is listed as well.

This paper describes extensions to a corpus annotation scheme for the manual annotation of attributions, as well as opinions, emotions, sentiments, speculations, evaluations and other private states in language. It discusses the scheme with respect to the “Pie in the Sky” Check List of Desirable Semantic Information for Annotation. We believe that the scheme is a good foundation for adding priv...
