Abstract: This paper demonstrates the development of a thermal error model that is applied on the feed axis of machine tools and based on the neural network. This model can accurately predict the value of the axial thermal error ...

Abstract: Direct-contact heat exchangers have great potential for waste-heat utilization. This study established a multi-objective evaluation model of the volumetric heat-transfer coefficient, entransy dissipation, and uniformity ...

Abstract: To solve the problem of identification damage in a cantilever retaining wall, a damage identification method for such a wall, based on the flexibility-difference mean curvature, is proposed. The concept of mean curvature ...

Abstract: Directcontact heat exchangers have great potential for wasteheat utilization. This study established a multiobjective evaluation model of the volumetric heattransfer coefficient, entransy dissipation, and uniformity of the ...

Abstract: Bat is the only mammal in the nature that can fly. Compared with birds and insects, bats are quite special in that their wings are formed by an elastic membrane, which renders that the airfoil deforms greatly during ...

Abstract: The flight of bats is comparatively less documented and understood than birds and insects and may provide novel inspiration for the design of flapping flight robots. This study captured the natural flight of short-nosed ...

Abstract: Based on the coordinate transformation method, the generalized turbulent lubrication equation considering the axial motion of the journal is derived. The finite-difference method is used to solve the generalized turbulent ...
