Introduction Deep-ultraviolet (DUV) laser is often applied to micro-fabrication of nonmetal materials because the materials strongly absorb the laser beam.
Silica glass and diamond-like materials are representatives of the materials hard to machine.
However, development of 157nm laser technology opens new opportunities for micromachining those materials.
Conclusions Deep-UV laser with 157nm wavelength is conducted into micromachining of wide band-gap materials.

This paper presents a new method to study the impact factor of an old bridge strengthened with high strength materials based on the model updating technique.
These damaged bridges were repaired recently using high strength materials, such as carbon fibre reinforced polymers (CFRP) and steel.
The department of transportation repaired the bridge using pre-stressed CFRP and steel materials (Fig.4).
Based on the origin design and inspection reports of the bridge, the repair method is that the CFRP materials were used to repair the floor of the box beam, the steel materials were used to repair the web of the box beam, and the repaired construction was done in 2001.
