Case Study Of An Automated Mower To Support Airport Sustainability, Sarah Hubbard, Adam Baxmeyer, Bryan Hubbard

Aviation Technology Faculty and Staff Publications

This paper documents a case study of an automated mower to support sustainability at an airport. Mowing is an essential component of an airport’s Wildlife Hazard Management Plan (WHMP), which reduces the risk of birds and other wildlife to aircraft operations. Many airports have large areas of land (hundreds or even thousands of acres), which requires significant resources to manage and mow; experience at the Purdue Airport (KLAF) suggests that automated mowing may support economic and environmental aspects of sustainability. Automated mowing supports economic efficiency by reducing personnel requirements, although personnel are still needed for inspections, maintenance, and “mower rescue” …

Riyadh Neighborhood Residents’ Use And Satisfaction With Urban Green Spaces, Tahar Ledraa, Majed Hallawani, Awad Al-Qahtani

Emirates Journal for Engineering Research

Neighborhood urban green spaces are indispensable elements for residents’ rest and recreation. They are also of paramount importance to enhance quality of life within neighborhoods. However, these urban green spaces did not receive much research interest, particularly in cities of the developing world. Larger city parks seem to have been the focus of studies. The present study is undertaken under the contention that dissatisfaction with a service is the difference between what is expected from that service and what is really experienced out of it. The gap between expectancy and what is experienced in reality would lead to how satisfied …

Learning-To-Dispatch: Reinforcement Learning Based Flight Planning Under Emergency, Kai Zhang, Yupeng Yang, Chengtao Xu, Dahai Liu, Houbing Song

Publications

The effectiveness of resource allocation under emergencies especially hurricane disasters is crucial. However, most researchers focus on emergency resource allocation in a ground transportation system. In this paper, we propose Learning-to- Dispatch (L2D), a reinforcement learning (RL) based air route dispatching system, that aims to add additional flights for hurricane evacuation while minimizing the airspace’s complexity and air traffic controller’s workload. Given a bipartite graph with weights that are learned from the historical flight data using RL in consideration of short- and long-term gains, we formulate the flight dispatch as an online maximum weight matching problem. Different from the conventional …

Helipad Detection From Satellite Imagery Using Convolutional Neural Networks, David Specht

Theses and Dissertations

Location data about U.S. heliports is often inaccurate or nonexistent in the FAA's databases, which leaves pilots and air ambulance operators with inaccurate information about where to find safe landing zones. In the 2018 FAA Reauthorization Act, Congress required the FAA to collect better information from the helicopter industry under part 157, which covers the construction, alteration, activation and deactivation of airports and heliports. At the same time, there is no requirement to report private helipads to the FAA when constructed or removed, and some public heliports do not have up to date records. This thesis proposes an autonomous system …
