AUV/ASC cooperative survey [PDF]

, 2016
In this paper we describe a solution to perform autonomous surveys taking advantage of a cooperative multivehicle setup. In the proposed configuration, an ASC provides –through an USBL- absolute positioning and communications to an AUV.

Light Curve Analysis of Hipparcos Data for the Massive O-type Eclipsing Binary UW CMa

, 2010
Hipparcos photometric data for the massive O-type binary UW CMa were analysed within the framework of the Roche model. Photometric solutions were obtained for five mass ratios in the $q=M_2/M_1=0.5-1.5$ range.

Absolute configuration and chemical topology

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1963
The stereochemistry of catenanes, knotted molecules, and Borromean rings is discussed. An augmentation of the Cahn-Ingold-Prelog convention for designating absolute configuration is proposed. A convention is proposed for designating the absolute configuration of knotted molecules. A suggestion is made concerning the citing of the absolute configuration
