We present a method that operates an electrolyzer to meet the demand of hydrogen refueling station in cost-effective manner by solving model-based optimal control problem. To formulate underlying problem, we first conduct experimental characterization Siemens SILYZER 100 polymer electrolyte membrane with \SI{100}{\kilo \watt} rated power. run experiments determine electrolyzer's conversion effi...

Alternative fuel vehicles may pose challenges to evacuation planning because of their short driving range and the sparse refueling infrastructure existing on transportation networks. Deployment strategic siting emergency stations are needed support alternative reach a shelter. This study proposes location-routing problem with hop constraints that optimize placement each type routing. We develop...

Autonomous aerial refueling (AAR) is the most effective way to extend unmanned aerial vehicles’ (UAV) endurance and improve their mission performance. A monocular vision based relative pose estimation (MVRP) method is proposed to solve the problem of close-range and high-accuracy relative pose estimation, which is very important and critical for AAR. MVRP is a feature point tracking based metho...

We develop a multi-period capacitated flow refueling location problem for electric vehicles (EVs) as the EV market responds to the charging infrastructure. The optimization model will help us determine the optimal location of level 3 chargers as well as the number of charging modules at each station over multiple time periods. Our model can also be applied to fast-filling gaseous alternative fu...

This paper formulates a mathematical model for the Green Vehicle Routing Problem (GVRP), incorporating bi-fuel (natural gas and gasoline) pickup trucks in a mixed vehicle fleet. The objective is to minimize overall costs relating to service (earliness and tardiness), transportation (fixed, variable and fuel), and carbon emissions. To reflect a real-world situation, the study considers: (1) a co...

Radioisotope 99 Mo is one of the most essential radioisotopes in nuclear medicine. Its production an Aqueous Homogeneous Reactor (AHR) could be potentially advantageous compared to traditional technology, based on target irradiation a heterogeneous reactor. An AHR conceptual design using low-enriched uranium for has been studied depth. So far, possibility replacing with non-uranium fuel, specif...
