The article discusses the experimental research by researchers at the Warsaw University of Technology of warsaw, Poland and the University of Savoie of Le Bourget du Lac, France on the problems of fabrication process for rapid prototyping. It develops binary phased-based diffracted lenses from a commercially purchased paper to address the fabrication process problem. It suggests that nonparaxial paper diffractive lens with terahertz radiation for quick prototyping.
Focuses on the completion of the first full-scale trial of a prototype noncontact laser ultrasound system that monitors paper quality during manufacture. Impact of such system on paper manufacturers; Features of the system; Measurement of the time it took for ultrasonic shock waves to travel.
Examines the usefulness of paper or plastic in the materials handling industry. Benefits of polyethylene pillows over paper dunnage; Percentage of all paper used in the U.S. that was recovered for recycling in 1999; Description of expanded polystyrene; Difficulty of using life cycle analysis to assess the overall impact on the environment of various materials.
