Abstract: Abstract. Thin-walled components are extensively utilized in aerospace applications but present significant machining challenges due to their low rigidity and time-varying dynamics. While existing adaptive control approaches ...

Abstract: The behavior of air bubble clusters rising in water and the induced flow field are numerically studied using a threedimensional twoway coupling algorithm based on a vortexincell (VIC) method. In this method, vortex elements ...

Abstract: A concentric face gear torque split system used in the helicopter main transmission to transfer more power and reduce the structure weight is introduced. A mathematical model is proposed to analyze the vibration characteristics ...

Abstract: The headon collision process of elliptic vortex rings was experimentally investigated using flowvisualization technique as well as particle image velocimetry (PIV). Elliptic vortex rings were generated by the movement of ...

Abstract: In this study, the same moles of alkali and alkaline earth metallic species were introduced into pine wood to investigate their effects on biomass pyrolysis and carbon dioxide-assisted gasification. First, thermogravimetric ...

Abstract: Abstract. Model uncertainty quantification is essential for enhancing the validity of simulations of nonlinear dynamic systems. However, its effectiveness may be significantly affected when experimental or monitoring data ...

Abstract: Torrefaction used for the pretreatment of biomass can enhance grindability along with a significant reduction of energy consumption required for pulverization to aid in large-scale utilization of biomass energy. In this ...

Abstract: Abstract A data-driven predictive model for dynamic deflection response can aid the safe operation and maintenance of a suspension bridge. In particular, it lays the groundwork for bridge condition assessment and damage ...

Abstract: Abstract. Co-pyrolysis of biomass and plastics offers synergistic effects, improves the distribution of pyrolysis products, and also enhances their quality. In this study, rice straw (RS) was co-pyrolyzed with polystyrene ...

Abstract: Abstract Starting from bridge design to the construction stage, accumulation of multiple errors related to manufacturing, installation, material properties, and other factors results in deviations between the actual completed ...
