Fast Simulation of Steady - State Availability

This paper considers eecient simulation techniques for estimating steady-state quantities in models of highly dependable computing systems with general component failure and repair time distributions. Earlier approaches in this application setting for steady-state estimation rely on the regenerative method of simulation, which can be used when the failure time distributions are exponentially di...

Optimization of Cutting Insert Geometry Using Deform-3d: Numerical Simulation and Experimental Validation

In this research work an attempt has been made to minimize flank wear of uncoated carbide inserts while machining AISI 1045 steel by finite element analysis. Tool wear is the predominant factor that causes poor surface finish and is responsible for the dimensional accuracy of the machined surface. The quality of component produced decides the effectiveness and competitiveness of any manufacturi...

Simulation Steady - State Simulation

We will discuss several techniques for obtaining point estimates and confidence intervals for steady-state performance measures. Let (X(t): t≥ 0) be a GSMP with (discrete) state space S that represents the underlying stochastic process of a simulation. Fix a real-valued function f defined on S and set Y(t) = f(X(t)) for t ≥ 0. There are several possible ways to define steady-state performance m...

A Numerical Approach for Analyzing Three-Dimensional Steady-State Rolling Contact Including Creep Using a Fast Semi-Analytical Method

Magnificent Grain Refinement of Al-Mg2Si Composite by Hot Rolling

The effect of chemical composition and the hot rolling operations on the microstructure and mechanical properties of in situ aluminum matrix composite with Mg2Si phase as the reinforcement was studied. It was revealed that the modification by phosphorous results in the rounder (more spherical) primary and secondary (eutectic) magnesium silicide intermetallics. During hot rolling, the primary pa...
