Alternative methods for dissimilar metal joining particularly aluminium and copper have gain interest in manufacturing sectors. Friction stir spot welding was carried out on the AA6061 C11000 wires of 2 mm diameter. This research paper reported results microstructures mechanical properties spot-welded joints, also special attention is provided electrical resistivity welds. The reveal informatio...

The paper presents a generalized composite noncertainty-equivalence adaptive control system for the of prototypical aeroelastic wing section using single trailing-edge surface. plunge–pitch (two-degree-of-freedom) dynamics this include torsional pitch-axis nonlinearity. open-loop exhibits limit cycle oscillations beyond critical free-stream velocity. It is assumed that parameters model are not ...

—Quantitative data on how high brook trout Salvelinus fontinalis can jump are crucial for efforts by fisheries managers to exclude brook trout from streams containing native cutthroat trout Oncorhynchus clarkii subspp. and to build effective fishways for brook trout migration. We identified factors that could influence brook trout jumping ability and demonstrated how this knowledge could be app...

Plunge milling is a machining process recognized to be efficient for roughing deep workpieces. This due the distribution of cutting forces on tool. Important axial and reduced radial lead more rigidity, eventually productivity. It commonly used in case hard cut materials, like titanium alloys. However, plunge can exhibit problem at end plunging phase, which increase forces. Within this paper, s...
