Abstract: The tribological properties of Fe–Cr–B alloys were studied sliding against SiC ball in liquid paraffin oil. The boron played an important role in improving tribological properties of alloys. The friction coefficients ...

Abstract: This study derives the equation for the bearing capacity of shallow circular foundation on the basis of the upper bound theorem of limit analysis method. The equation is derived by considering the work of soil weight and ...

Abstract: An approach is proposed to obtain the global analytical modes (GAMs) and establish discrete dynamic model with low degree-of-freedom for a three-axis attitude stabilized spacecraft installed with a pair of solar arrays. ...

Abstract: A survey of 1,244 households in three representative Chinese provinces was undertaken to assess energy consumption and cost for rural and urban residents. After accessing a considerable amount of information on energy ...

Abstract: Glass fiber–reinforced polymer (GFRP) materials provide practical solutions to corrosion and site-maneuvering problems for civil infrastructures using conventional steel bars as reinforcements. In this study, the feasibility ...

Abstract: Little attention has been paid to the fast-growing biohazardous wastewater (BHW) in recent years, even though it may pose severe biohazards and toxicity to the general public and environment. Two processes including Fenton ...

Abstract: Heat transfer characteristics for condensation for R410A inside horizontal round (dh = 3.78 mm) and flattened tubes (aspect ratio (AR) = 3.07, 4.23, and 5.39) with larger horizontal than vertical dimensions at a saturation ...

Abstract: Large-aperture parabolic trough collectors (LPTCs) are recognized as one of the most promising next-generation linear-focus concentrating solar power (CSP) technologies. However, large apertures inevitably introduce higher ...
