The morphological properties of the Carina, Sculptor and Fornax dwarfs are investigated using new wide field data with a total area of 29 square degrees. The stellar density maps are derived, showing that Sculptor possesses tidal tails indicating interaction with the Milky Way. Contrary to previous studies we cannot find any sign of breaks in the density profiles for the Carina and Fornax dwarf...

by Alfred Aho, Sean Gallagher, Nancy Griffeth, Cynthia Schell, and Deborah Swayne Abstract We describe a language called Chisel and an editing tool for Chisel called Sculptor for defining requirements for communications services. The purpose of Sculptor and Chisel is to speed the service creation process by improving communication between organizations, by automating tedious manual work, and by...

Reasoning with Narratives’ is an attempt to combine narrative theory with theories of knowledge representation and knowledge acquisition in order to establish a foundation for computer aided narrative analysis. The theoretical foundation in the area of narratology is mainly derived from a structural approach. A number of narratologies are examined, and a unified model based on the notions of su...

Hans Elias (1907 to 1985) was an anatomist, an educator, a mathematician, a cinematographer, a painter, and a sculptor. Above all, he was a German of Jewish descent, who had to leave his home country because of the policies of the National Socialist (NS) regime. He spent his life in exile, first in Italy and then in the United States. His biography is exemplary for a generation of younger expat...

The results of a wide-field survey of the Sculptor dwarf spheroidal galaxy are presented. Our aims were to obtain an accurate map of the outer structure of Sculptor, and to determine the level of interaction between this system and the Galaxy. Photom-etry was obtained in two colours down to the magnitude limits of V = 20 and I = 19, covering a 3.1 × 3.1 deg 2 area centred on Sculptor. The resul...

We present an analysis of Hubble Space Telescope/WFPC2 images of nine nearby galaxies in Sculptor. We derive their distances from the luminosity of the tip of the red giant branch stars with a typical accuracy of ∼ 12 %. Their distances are 4.21 Mpc (Sc 22), 4.92 Mpc (DDO 226), 3.94 Mpc (NGC 253), 3.40 Mpc (KDG 2), 3.34 Mpc (DDO 6), 3.42 Mpc (ESO 540-030), 4.43 Mpc (ESO 245–05), 4.27 Mpc (UGCA ...

We present new Hα narrow band imaging of the HII regions in eight Sculptor Group dwarf irregular (dI) galaxies. The Hα luminosities of the detected HII regions range from some of the faintest detected in extragalactic HII regions (∼ 10 erg s in SC 24) to some of the most luminous (∼ 10 erg s in NGC 625). The total Hα luminosities are converted into current star formation rates (SFR). Comparing ...

Given a graph H and an integer r ≥ 2, let G → (H, r) denote the Ramsey property of a graph G, that is, every r-coloring of the edges of G results in a monochromatic copy of H. Further, let m(G) = maxF⊆G |E(F )|/|V (F )| and define the Ramsey density minf (H, r) as the infimum of m(G) over all graphs G such that G → (H, r). In the first part of this paper we show that when H is a complete graph ...
