Abstract: The hand motions which are observed when one holds an object and transfers it to a specified position are analyzed and a proposed mathematical model is compared with the real movements. The ...

Abstract: For a gas diffusion cathode for oxygen reduction reaction (ORR) in aqueous alkaline electrolyte, it is important to create networks for O2 gas diffusion, electronic conduction, and liquid-phase OH− transport in the cathode ...

Abstract: We present an experimental study on the nonlinear dynamics of combustion instability in a lean premixed gas-turbine model combustor with a swirl-stabilized turbulent flame. Intermittent combustion oscillations switching ...

Abstract: The objective of this study is to determine the differences in flow fields between the 30 deg in-line and staggered arrangements of teardrop-shaped dimples, and to explain why the surface-averaged Nusselt number with the ...

Abstract: The objective of this study is to clarify the effects of the film-cooling flow pulsation and the differences between the Strouhal number ratios of 1.0 and √2. The surface-averaged film cooling effectiveness for the Strouhal ...

Abstract: Different from postfailure maintenance in many perspectives, preventive maintenance of civil engineering structures is another highly crucial measure, not only for achieving efficient distribution of limited budget over ...

Abstract: The authors developed 1400 °C (2552 °F) class ceramic matrix composite (CMC) material system, which consists of silicon carbide (SiC) fibers and SiC matrix and ytterbium silicate base matrix, aiming for higher temperature ...
