Path planning related to mobile robots is the construction of the collision free trajectories that direct robots towards their goal. In this paper, a bio inspired approach based on the foraging behaviour of the bacteria (E-coli) has been proposed to design an optimal path for the robot. The present approach admires that the mobile robot is capable of reaching the goal by following the optimum p...

In this paper, the optimum shape of Tailor-Welded Blanks (TWB) is investigated. The optimization is performed for two different case studies. The first example is deep drawing of a TWB with dissimilar materials and uniform thicknesses and the next example is deep drawing of a TWB with similar materials and non-uniform thicknesses. The effect of blank optimization on the weld line movement is...

on waste can alter the optimum transition path. In the optima with recycle, the lower waste penalty from reduced buildup of 239Pu more than compensates for the separations and fuel fabrication facility costs. Figure 3 shows this buildup for each of the runs. However, with a high repository discount (run 3) recycle technology is unable to compete with cheap direct disposal. The optimum in run 4 ...

machines using ball end mill cutters; the determination of the optimum tool and the minimization of the machining times for each surface. In the proposed methodology, the accessibility problem is first analyzed and then the optimal tool is selected from a database of tools. Next, and depending on the machining method, we select automatically the optimum sweeping method and the associated machin...

Heterogeneous systems are nowadays a common choice in the path to Exascale. Through the use of accelerators they offer outstanding energy efficiency. The programming of these devices employs the host-device model, which is suboptimal as CPU remains idle during kernel executions, but still consumes energy. Making the CPU contribute computing effort might improve the performance and energy consum...
