Abstract: Based on the unified analytical (UA) method and the unified and refined analytical (URA) method of stress analysis for fixed tubesheet (TS) heat exchangers (HEXs), floating head, and U-tube HEXs, the applicable configuration ...

Abstract: By introducing the modular and reconfigurable design, the limbs of a hexapod robot can be assembled into different configurations to meet various task requirements. Contrary to the fixed configuration system, the task ...

Abstract: A tunable metamaterial is proposed by combining a thermochromic oxide with a fishnet structure. The reflection and transmission coefficients are calculated by finitedifference timedomain (FDTD) method. The effective ...

Abstract: A model that couples the rock matrix and fracture flow is employed to simulate the flow and solute transport in fractured porous media. The porous matrix is represented using an equivalent continuum model, and discrete ...

Abstract: The stress analysis method for fixed tubesheet (TS) heat exchangers (HEX) in pressure vessel codes such as ASME VIII1, EN13445, and GB151 all assume a geometric and loading plane of symmetry at the midway between the two ...

Abstract: Asphalt pavements on steep slope sections in regions with seasonal freezing are affected by loads and the environment, and the shear resistance and shear fatigue performance attenuation of interlayer adhesive materials ...

Abstract: The problem of horizontal-plane tracking control of an omnidirectional, four vectored-thruster aerostat subjected to actuator failure is considered. The actuator failures result in the aerostat’s becoming underactuated, ...
