Sun, Junzi (author)Trajectory optimization has been an active area of research for air transport studies for several decades. But almost all flight optimizers proposed in the literature remain close-sourced, which presents a major disadvantage for the advancement of scientific research. This optimization depends on aircraft performance models, emission models, and...journal article 2022

Ferreira de Brito, B.F. (author), Agarwal, Achin (author), Alonso-Mora, J. (author)Autonomous navigation in dense traffic scenarios remains challenging for autonomous vehicles (AVs) because the intentions of other drivers are not directly observable and AVs have to deal with a wide range of driving behaviors. To maneuver through dense traffic, AVs must be able to reason how their actions affect others (interaction model)...journal article 2022

Niklaβ, Malte (author), Grewe, V. (author), Gollnick, Volker (author), Dahlmann, Katrin (author)Approximately 50–75% of aviation's climate impact is caused by non-CO<sub>2</sub> effects, like the production of ozone and the formation of contrail cirrus clouds, which can be effectively prevented by re-routing flights around highly climate-sensitive areas. Here, we discuss options how to incentivize re-routing approaches and apply...journal article 2021

Magyar, Bence (author), Tsiogkas, Nikolaos (author), Ferreira de Brito, B.F. (author), Patel, Mayank (author), Lane, David (author), Wang, Sen (author)Learning from Demonstration (LfD) is a family of methods used to teach robots specific tasks. It is used to assist them with the increasing difficulty of performing manipulation tasks in a scalable manner. The state-of-the-art in collaborative robots allows for simple LfD approaches that can handle limited parameter changes of a task. These...journal article 2019

Heiligers, M.J. (author), Fernandez, Juan M. (author), Stohlman, Olive R. (author), Wilkie, W. Keats (author)This paper proposes the use of solar-sail technology currently under development at NASA Langley Research Center for a CubeSat rendezvous mission with asteroid 2016 HO3, a quasi-satellite of Earth. Time-optimal trajectories are sought for within a 2022–2023 launch window, starting from an assumed launcher ejection condition in the Earth-Moon...journal article 2019

Ho-Huu, V. (author), Hartjes, S. (author), Visser, H.G. (author), Curran, R. (author)In an effort to allow to increase the number of aircraft and airport operations while mitigating their negative impacts (e.g., noise and pollutant emission) on near-airport communities, the optimal design of new departure routes with less noise and fuel consumption becomes more important. In this paper, a multi-objective evolutionary algorithm...journal article 2017
