In this paper we develop a methodology for systematically constructing redundant finite-state machines in a way that enables an external mechanism to detect and identify transient state-transition faults by performing checks in a non-concurrent manner (e.g., periodically). More specifically, by characterizing non-concurrent error detection / identification capabilities in terms of state encodin...

in this paper, a three-dimensional finite element model has been developed to simulate the laser-tig hybrid welding (hlaw) of stainless steel 1.4418 with thickness of 4 mm. transient temperature profile and dimensions of the fusion zone and heat affected zone (haz) during welding process are calculatedusing finite element method (fem) and were solved in the abaqus/standard software.the heat sou...

Strictly stable high order finite difference methods based on Tam and Webb’s dispersion relation preserving schemes have been constructed. The methods have been implemented for a 1D hyperbolic test problem, and the theoretical order of accuracy is observed.

This paper presents time-transient polarimetric analysis for a simplified bridge model on water Surface. We extend our previous 2D time-transient analysis to 3D polarimetric scattering problem. Here the Finite-Difference Time-Domain (FDTD) method is utilized. In addition to the time-transient feature, we focus on the generating mechanism of the volume scattering component with increase of the s...

In the present study, the transient stress distribution caused by a break in the fibers of an adhesive bonding is investigated. Transient stress is a dynamic response of the system to any discontinuity in the fibers from detachment time till their equilibrium state (or steady state). To derive the governing dynamic equilibrium equations shear lag model is used. Here, it is assumed that the tens...

In digital sequential systems that operate over several time steps, a state-transition fault at any time step during the operation of the system corrupts its state in a way that can render its future functionality useless. In this paper, we develop a methodology for systematically constructing redundant £nitestate machines so that an external checker can capture transient state-transition fault...

With due attention to the fact that the local and foreign vehicle industries are changing and modifying the previous designs in order to produce new designs, the components of self-propelled are to be differently analyzed. Static and dynamic analysis is one of them. In this paper, chassis and body of a o-457 bus were studied and analyzed under finite element method (using ANSYS).This process wa...
