The extension of back-arc basins and formation marginal seas following the subduction oceanic lithosphere are usually attributed to rollback subducting slabs distorted mantle convection. However, for Japan Sea, largest sea in northwestern Pacific, its opening is unlikely only resulted from Pacific plate because coeval Philippine arcuate arc volcanic zone. Therefore, present-day thermal structur...

Located in the southern margin of Central Asian orogenic belt, stratigraphy and tectonic setting mafic 290−280 Ma Liuyuan Complex have been controversial for decades, with workers arguing a forearc ophiolite or continental rift setting. Here, we present results detailed field study, where was subdivided into troctolite, melatroctolite, layered gabbro, varitextured olivine hornblende plagiograni...

As the year draws to an end, it is wonderful to look back at the Centre achievements over the past year and, in particular, the last six months. This has only been possible due to the dedicated work of the QMNC members! Our grants successes in the last rounds were very notable with outstanding success rates in the ARC Future Fellowship, Discovery Project and Linkage Project rounds relative to t...

This paper describes the development of a selfdriving mobile welding robot. The robot is used to weld U-shaped welding areas in enclosed double-hull structures. In order to place itself inside the double-hull structure, the robot is capable of passing through an access hole 600 mm wide and 800 mm high. This research addresses the mechanical and control systems of the robot. The mechanical syste...

Scanning a halftone image introduces halftone artifacts, known as Moire patterns, which significantly degrade the image quality. Printers that use amplitude modulation (AM) screening for halftone printing position dots in a periodic pattern. Therefore, frequencies relating half toning arc easily identifiable in the frequency domain. This paper proposes a method for de screening scanned color ha...
