Abstract: The stability of tunnel roof is investigated in nonhomogeneous soils using the theory of plasticity. Based on the nonlinear failure criterion, the expressions of tunnel roof in nonhomogeneous soils are deduced, and the ...

Abstract: The quality of parts produced by a composite tape-laying process is sensitive to the contact force exerted and the abutment of adjacent tape courses kept when the tapes are laid. Thus, a ...

Abstract: The calibration scheme of robot forward kinematics presented in this paper has a number of features. Firstly, robot kinematic errors are modeled in a recursive format and as such, the number ...

Abstract: Sensor fusion often uses multiple sensors to evaluate a single quantity. The work presented in this paper attempts to use information from a single sensor to estimate overall machining performance ...

Abstract: In order to investigate the possibility of numerical simulation for whole structures of heat exchangers, two finite element analysis models have been established for the fixed tubesheet structure ...

Abstract: Although considerable effort has gone into characterizing the laser forming process in terms of process parameters and conditions, there has been little emphasis on the effects of the mechanical ...
