A major challenge for glass X-ray tube makers is the reduction in the tube size for portable or handheld applications. Size reduction is difficult mainly due to contact size restrictions for glass-to-metal welding. In high-voltage (60–70 kV) portab

For general multiobjective optimization problems, the usual goal is finding the set of solutions not dominated by any other solutions, that is, a set of solutions as good as any other solution in all objectives and strictly better in at least one obj

When simulating a complex stochastic system, the behavior of output response depends on input parameters estimated from finite real-world data, and the finiteness of data brings input uncertainty into the system. The quantification of the impact of i
