A DATA-DRIVEN RELIABILITY ESTIMATION APPROACH FOR PHASED-MISSION SYSTEMS
We attempt to address the issues associated with reliability estimation for phased-mission systems (PMS) and present a novel datadriven approach to achieve reliability estimation for PMS using the condition monitoring information and degradation data of such system under dynamic operating scenario. In this sense, this paper differs from the existing methods only considering the static scenario wit...

NUMERICAL PERFORMANCE OF HIGHER-ORDER SEMICOMPACT SCHEME FOR ARBITRARY TRIANGULAR CAVITY FLOW
An efficient fourth-order semicompact finite difference scheme has been developed to solve steady incompressible Navier-Stokes (N-S) equations in stream function and vorticity formulation in a triangular cavity of arbitrary geometry. The governing equations are transformed into curvilinear coordinates by a simple linear transformation to handle the nonregular geometry of the problem. The main feat...

INVESTIGATION OF THROUGH-THICKNESS STRESSES IN COMPOSITE LAMINATES USING LAYERWISE THEORY
In this study, an analytical method is developed to exactly obtain the interlaminar stresses near the free edges of laminated composite plates under the bending moment based on the reduced form of elasticity displacement field for a long laminate. The analytical and numerical studies were performed based on the Reddy’s layerwise theory for the boundary layer stresses within cross-ply, symmetric,...

D-FNN BASED MODELING AND BP NEURAL NETWORK DECOUPLING CONTROL OF PVC STRIPPING PROCESS
PVC stripping process is a kind of complicated industrial process with characteristics of highly nonlinear and time varying. Aiming at the problem of establishing the accurate mathematics model due to the multivariable coupling and big time delay, the dynamic fuzzy neural network (D-FNN) is adopted to establish the PVC stripping process model based on the actual process operation datum. Then, the ...

A NETWORK DEA MODEL WITH SUPER EFFICIENCY AND UNDESIRABLE OUTPUTS: AN APPLICATION TO BANK EFFICIENCY IN CHINA
There are two typical subprocesses in bank production—deposit generation and loan generation. Aiming to open the black box of input-output production of banks and provide comprehensive and accurate assessment on the efficiency of each stage, this paper proposes a two-stage network model with bad outputs and supper efficiency (US-NSBM). Empirical comparisons show that the US-NSBM may be promising...

ROTATORY CONDITION AT INITIAL STAGE OF EXTERNAL SPLINE ROLLING
In spline rolling process, the billet is mainly driven by frictional moment at initial forming stage that from starting rolling to billet/workpiece rotated half circle. If the rotation of billet is not normally driven by rolling die, then the motion between billet and rolling die is not coordinated, and then dividing precision of external spline will be reduced.Thus, the rotatory condition of ro...
