In order to improve the reliability of micro-spot welding of metal parts in production such as e.g. in electron guns for TV picture tubes, real-time information about the evolution of the welding process should be available to allow on-line modification of ...
The tensile failure of fiber-reinforced composites in 2D (l-ply) and thin multi-ply samples has been studied numerically in order to assess the role of dimensionality on the absolute magnitude, reliability, and size scaling of composite strength. Single-pl ...

In view of the laboratory tests performed at PSI with a Nafion tubular membrane reactor module for the catalysed methanol synthesis with CO2 and H-2 at 200 degrees C, the mechanical stability of a commercially available Nafion hollow fiber was tested at el ...
We demonstrate the possibility of broadening the emissions spectra of superfluorescent fiber lasers by combinations of different kinds of single-mode doped silica fibers. We obtained an optical bandwidth of more than 70 nm (FWHM) between 1030 and 1100 nm u ...
Pd and Pt supported on glass fiber materials with developed porosity and high sp. surface areas were studied in total propane oxidn. The reaction was carried out in recycling reactor and the kinetic parameters were detd. under different reaction conditions ...
A low wt. resistant porous glass fiber with a developed sp. surface area of 5-120 times the outer surface of a std. glass fiber, and a material having phys., chem. or biol. reactive properties deposited on the developed surface area of porous glass fiber a ...
(Ecole Polytechnique Federale De Lausanne, Switz.).2000
A low weight resistant porous glass fiber of type I is disclosed with a developed specific surface area of 5 times to 120 times the outer surface of a standard glass fiber, and a material having physical, chemical or biological reactive properties deposite ...
The oscillatory behavior during CO oxidn. over Pd supported on glass fibers was studied in a recycle reactor. The properties of oscillations as a function of temp. and inlet CO concn. were investigated in detail. The peculiarity of the obsd. oscillations i ...
A complete set-up for local annealing of Shape Memory Alloys (SMA) is proposed. Such alloys, when plastically deformed at a given low temperature, have the ability to recover a previously memorised shape simply by heating up to a higher temperature. They f ...
