The effects of breathing on body roll have been previously investigated for the roll of the whole trunk only. The purposes of this study were: to calculate separately the shoulder roll (SR) and hip roll (HR) of swimmers during front crawl for non-breathing and preferred-side breathing conditions; to assess the differences in the magnitude and temporal characteristics of these variables between ...

The optimization of flexible thin-film thermoelectric generators (TEGs) suitable for large-area roll-to-roll (R2R) processing is investigated. selection contact materials, in-line patterning connections, and dimension the (TE) strip are studied. As a result, copper selected contacts because it possesses similar performance to gold while being cheaper. Both in-series- in-parallel-connected devic...

In rolls manufactured from first bent and then welded sheets of steel, the asymmetric distribution mass due to weld seam as well imperfections geometry bending may cause roll cross-section roundness profiles deform centrifugal forces when is accelerated rotate at its operating speed. This effect known dynamic roll. previous research, it has been shown that possible measure in speed compensate f...

Abstract. To increase the sustainability of forming processes such as punch bending, homogenization processed semi-finished product is an essential step in manufacturing process. High-strength wire materials are usually available strip material before being further a For storage and transport, coiled onto coils transported to customer. During coiling process, residual stresses plastic deformati...

The proposed surface water and ocean topography (SWOT) mission aims at observing short scale ocean topography with an unprecedented resolution and accuracy. Its main proposed sensor is a radar interferometer, so a major source of topography error is the roll angle: the relative positions of SWOT’s antennas must be known within a few micrometers. Because reaching SWOT’s stringent requirements wi...

The mechanical and acoustic properties of four commonly used wood species, including Populus tomentosa (Poplar), Swietenia mahagoni (Mahogany), Fagus orientalis (Beech), Fraxinus excelsior (Ash) were investigated through using three-point bending notched tests synchronizing with power spectrum analysis method fractal dimension theory. results showed that the modulus elasticity rapture changed i...
