On January 19, 1996 we published in the Internet a demo of how to use Self-Organizing Maps (SOMs) for the organization of large collections of full-text les. Later we added other newsgroups to the demo. It can be found at the address http://websom.hut../websom/. In the present paper we describe the main features of this system, called the WEBSOM, as well as some newer developments of it.
The current study set out to evaluate how individuals walk through apertures created by different stationary obstacles. Specifically, we examined whether the passability of apertures differed between human and pole obstacles by quantifying aperture crossing behaviors such as the critical point. Participants walked an 8m path toward a visible goal located at the end. Two obstacles were positione...
The in-plane optical anisotropy (IPOA) in InAs/GaSb superlattices has been studied by reflectance difference spectroscopy (RDS) at different temperatures ranging from 80 to 300 K. We introduce alternate GaAs- and InSb-like interfaces (IFs), which cause the symmetry reduced from D 2d to C 2v . IPOA has been observed in the (001) plane along [110] and [1[Formula: see text]0] axes. RDS measurement...
INTRODUCTION Ethiopia has a growing private health sector. In recent years, the directly observed treatment short course (DOTS) strategy was initiated in selected private health facilities in the country. The objective of the present study was to assess knowledge and practice of private practitioners in tuberculosis (TB) control in Amhara Region, Ethiopia. METHODOLOGY An institution-based cro...
