This paper analyzes the problem of global disassembly of a selected component from a geometrically constrained assembly. The geometric constraints are: (i) spatial constraints due to the three-dimensional geometric interactions between the components in an assembly; and (ii) user-defined constraints, such as grouping of components as subassemblies and directional constraints on component geomet...

The all-time behavior provides a robustness algorithm by allowing it to be interrupted at any point in the process, while ensuring that the best possible response is delivered when the stop request occurs. This work proposes a methodology to identify the relationship of the parameters of an optimization algorithm by colony of ants with its behavior at-all-moment, allowing to implement a techniq...

in this paper, a supplier-retailer transportation system is investigated as a two-echelon environment. there is a single location in each echelon; the unique supplier at the first echelon has to replenish the retailer's warehouse at the second echelon. by the way, the shortage situation should be avoided. for this situation, a model is provided based on the traditional eoq model. the inven...

This article proposes a novel graphics processing unit-based active nematic flow solver based on the smoothed particle hydrodynamics (SPH) method. Nematohydrodynamics equations are discretized using SPH algorithm. Flow behavior, ordering, topological defects, and vorticity correlation calculated discussed in detail. The spectrum of kinetic energy with respect to wavenumber is at high resolution...

Estimating and minimizing the maximum power dissipation during testing is an important task in VLSI circuit realization since the power value affects the reliability of the circuits. Therefore during testing a methodology should be adopted to minimize power consumption. Test patterns generated with –D 1 option of ATALANTA contains don’t care bits (x bits). By suitable filling of don’t cares can...
