We revisit the peer-to-peer on-orbit satellite refueling problem, in which the maneuvering satellites are allowed to interchange their orbital positions. We show that the problem is computationally hard by reducing it to a special case of the three-index assignment problem. On the positive side, we show that the size of instances in practice is such that a state-of-the-art integer programming s...

As the world looks ahead to the next generation of space exploration programs, we must focus on designing architectures for both sustainability and affordability. By viewing exploration programs as a “system-of-systems,” we can focus on reducing costs through the use of flexible, reusable infrastructures to support various aspects of manned and unmanned spaceflight. This paper addresses one key...

Modern electrical transportation systems require eco-friendly refueling stations worldwide. This has attracted the interest of researchers toward a feasible optimal solution for electric vehicle (EV) charging stations. EV can be simply classified as Slow (domestic use), Fast and Ultrafast (commercial use). study highlights recent advancements in commercial DC charging. The battery voltage varie...

LOTUS reactor - a compact lead-cooled fast is currently being studied to generate 200 MWth of capacity and operate for 20 years without refueling the floating nuclear power plant (FNPP) application. Therefore, it would be big advantage achieve long operation refueling. However, small usually has higher neutron leakage, good reflector essential maintain economy. The main objective selecting pote...
