Based on spatial and DCT domains this paper proposes a novel digital watermark solution for the color image of screen stream in multimedia courseware. It embeds visible watermark into spatial domain adaptively, and also embeds invisible watermark encrypted by chaotic sequence into the remained area of the screen color image to achieve protected screencolor image with dual digital watermark embedded...
We present the use of swept wavelength interferometry for distributed fiber-optic temperature measurements in a nuclear reactor. The sensors consisted of 2-m segments of commercially available, single mode optical fibers. The interrogation technique is based on measuring the spectral shift of the intrinsic Rayleigh backscatter signal along the optical fiber and converting the spectral shift to temperature.
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
