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 …

Fatigue And Its Management In The Aviation Industry, With Special Reference To Pilots, Rajee Olaganathan, Timothy B. Holt, Jackie Luedtke, Brent D. Bowen

Journal of Aviation Technology and Engineering

Abstract Fatigue is a significant contributing factor that reduces human ability and leads to accidents and threatens the safety of aircraft and human lives. Approximately 70% of fatal accidents that occur in commercial aviation operations are due to human factors. More specifically, crew fatigue contributes to nearly 15 to 20% of the accidents (Akerstedt, 2000). These accidents and incidents are associated with pilot fatigue because of the long duty periods, disruption of circadian rhythms, and inadequate sleep that are common among both commercial and military pilots. Though fatigue is seen in all the disciplines associated with the aviation industry, this …

Comparison Of Airline Co-Branded Credit Card Programs Via Frequent Flyer Money Saver Analysis For Full-Service U.S. Carriers, Bora Suavi Unsal

Doctoral Dissertations and Master's Theses

Although airline alliances work fairly effectively for paid flight segments, passengers who want to redeem frequent flyer miles often encounter difficulties. Sometimes airlines demand an extensive amount of air miles to book requests for award seats to not only their partner airline customers but also their own customers. Furthermore, while the airline co-branded credit card award mile earnings and redemption rates fluctuate significantly between different airlines, passengers are not well informed about which airline co-branded credit card requires the minimum amount of credit card expenditure to fly with an award ticket to their desired travel destination.

Soarnet, Deep Learning Thermal Detection For Free Flight, Jake T. Tallman

Master's Theses

Thermals are regions of rising hot air formed on the ground through the warming of the surface by the sun. Thermals are commonly used by birds and glider pilots to extend flight duration, increase cross-country distance, and conserve energy. This kind of powerless flight using natural sources of lift is called soaring. Once a thermal is encountered, the pilot flies in circles to keep within the thermal, so gaining altitude before flying off to the next thermal and towards the destination. A single thermal can net a pilot thousands of feet of elevation gain, however estimating thermal locations is not …
