(2018-12-11)This thesis examines an orbit control problem for a spacecraft around a contact binary asteroid considering the dynamics of both the spacecraft and the asteroid itself. It is known that approximately 15\% of the near-Earth ...
(2018-12-06)Establishing long-term human presence beyond low Earth-orbit will require cooperative use of emerging technologies, such as low-thrust solar electric propulsion, along with existing space exploration technologies. Trajectory ...
Hamilton-Jacobi-Bellman equation for stochastic optimal control: Applications to spacecraft attitude control (2018-12-14)This study aims to address the problem of attitude control of spacecraft in presence of thrust uncertainty, which leads to stochastic accelerations. Spacecraft equipped with electric propulsion and other low thrust mechanisms, ...
(2018-12-04)A model system was designed and investigated experimentally to gain insight into the interactions of an air-filled cylindrical bubble immersed in hydrogel, a compliant boundary, and a transient loading wave. This combination ...
Velocity, temperature, and electric field measurements on a plasma-assisted hydrogen diffusion flame (2018-11-08)A plasma-assisted hydrogen diffusion flame, denoted as a coaxial AC DBD burner, was designed and analyzed for comparisons with simulations and to better understand the coupling of the plasma and reacting flow. Emission, ...
