Object-Oriented Finite element analysis (OOF) has recently been shown as an effective tool for evaluating thermo-mechanical material behaviour, because of its capability to incorporate the inherent material microstructure as an input to the model. The complexity of a thermal sprayed microstructure makes it difficult to model and simulate by classical analytical or numerical techniques and thus very appropriate for this approach. In this paper instrumented micro-indentation and meshing in the OOF program was combined with a nonlinear finite element analysis to determine elastic-plastic properties of thermal sprayed Ti2AlC coatings; the significance of the findings is discussed in this article.

With appropriate assumptions, this paper gives a stochastic model on the ATMs which provide cash service to the people who need to get money from the bank and gives a formula which can offer the gross of the money provided to the people when the number of people obeys Poisson distribution and the the quantity of money obeys Normal distribution. Besides, this paper gives a conclusion with stochastic simulation.

Mass property of space vehicle changes apparently during and after mating and cannot be predicted or measured at times, yet it needs to be accurately known for mated flight control or attitude control and momentum management. A discrete Kalman Filter (KF) based estimation method is developed, measurements of single point acceleration, angular velocity and angular acceleration are employed to extract the inertia matrix and mass center. Simulation results show that the method can be used for continues online estimation without propellant consumption.
