Laser welding of AZ61 magnesium alloys was carried out asing a CO2 laser weldingexperimental system.The welding properties of AZ61 sheets with different thickne
Torus bifurcation is a relatively complicated bifurcation caused by a pair of complex conjuployed to reveal the relationship between torus bifurcation and some
While some applications in memory can be constrained by memory bandwidth and memory cost, this paper proposes a transformation of the application into a one-bit
A principal direction Gaussian image (PDGI)-based algorithm is proposed to extract the regular swept surface from point cloud. Firstly, the PDGI of the regular
The high flexibility of profile bending with hyperelastic pad enables it to be a promising method for small lot or single part production, especially for space
Some key techniques for the development of web-based product data management (PDM) system are introduced. The four-tiered B/S architecture of a PDM system-BITPD
A new type of variable polarity welding power modulated with high-frequency pulse current is developed.Series of high-frequency pulse current is superimposed on
This article proposes an energy efficient clustering routing (EECR) algorithm for wireless sensor network. The algorithm can divide a sensor network into a few
