Abstract: The effect of laser welding on prevention of the fracture of cracked shafts of a high carbon steel are presented. Static tensile strength and rotary bending fatigue strength were obtained using ...

Abstract: This paper investigates the effect of laser hardening on cracked steel specimens. After laser hardening around precracked shafts of SAE 1015 steel, rotary bending fatigue strength was determined. ...

Abstract: This paper investigates the effect of laser welding on the prevention of fracture of cracked steel specimens. Precracks occurred in shaft specimens of SAE 1015 were welded by a CO2 laser, and ...

Abstract: Three systems have been proposed for advanced high-temperature gas-cooled reactors: a supercritical carbon dioxide (S-CO2) gas turbine power conversion system, a new microchannel heat exchanger ...

Abstract: Interannual variability of the global radiation budget, regions that contribute to its variability, and what limits albedo variability are investigated using Clouds and the Earth?s Radiant Energy System (CERES) data taken ...

Abstract: This paper describes the use of a mechanical pectoral fin as a new device for maneuvering and stabilizing an underwater vehicle. The mechanical pectoral fin consists of two servo-motors generating ...

Abstract: This paper reviews the studies on the kinematics, hydrodynamics, and performance of median and paired fin (MPF) in fish and biomimetic mechanical systems from the viewpoint of enhancing the ...

Abstract: A one-dimensional radiative transfer algorithm that accounts for correlations between the optical thickness and the incident direct solar radiation is developed to compute the domain-averaged shortwave irradiance profile. ...

Abstract: A new method was developed to find the interface pressure distribution of metallic surfaces in contact by measuring the roughness change. The pressure distribution of two kinds of contact ...
