Photocatalytic oxidation (PCO) is a maturing process technology that shows potential for spacecraft life support system application. Incorporating PCO into a spacecraft cabin atmosphere revitalization system requires an understanding of basic performance, particularly with regard to partial oxidation product production. Four PCO reactor design concepts have been evaluated for their effectiveness for mineralizing key trace volatile organic compounds (VOC) typically observed in crewed spacecraft cabin atmospheres. Mineralization efficiency and selectivity for partial oxidation products are compared for the reactor design concepts. The role of PCO in a spacecraft's life support system architecture is discussed.
In this paper, we present a Bernstein polynomial approach to optimally and reliably solve polynomial class of mixed-integer programming (MIP) problems. We use the Bernstein form in the branch-and-bound framework to co...

In this paper, we present a Bernstein polynomial approach to optimally and reliably solve polynomial class of mixed-integer programming (MIP) problems. We use the Bernstein form in the branch-and-bound framework to compute a global optimum of MIPs. We present two application examples of MIPs: optimal pump configuration problem and trim loss minimization, to demonstrate the Bernstein polynomial approach.
This paper is concerned with the computation of optimal motion control as well as the optimal input injection policy of an actuator arm regulating the temperature in a reaction-diffusion system. The system has two dyn...

With the addition of online laboratories, distance education can become more meaningful and complete. This paper presents a virtual lab established through LabVIEW data socket technology that enables the end user to design and implement control algorithms. Although this makes the problem more challenging, the quality of learning is also enhanced enormously. We demonstrate this lab through an open source, low cost, single board heater system. A large number experiments have been conducted using this setup.
