Potential airport capacity gains from the optimal assignment of aircraft types to runways
… capacity by optimally allocating aircraft to runways such that the overall inter-arrival time between successive aircraft is minimized and the total capacity thus maximized. A mathematical model is presented that consists of two parts: an optimization based on analytic formulations and …

Approximate Algorithms for the Combined arrival-Departure Aircraft Sequencing and Reactive Scheduling Problems on Multiple Runways
… The dissertation examines the ASP over multiple runways, under mixed mode operations with the objective of minimizing the total weighted tardiness of aircraft landings and departures simultaneously. To prevent the dangers associated with wake-vortex effects, separation times enforced by Aviation …

Evaluation of selected airport pavements in New Mexico
… poor performance with a value of 183.6 ksi, 3 runways have fair MR values, and 10 runways have satisfactory MR values. An indirect tension modulus of 300 ksi is considered to be good for existing surface course. The MR value is used in mechanistic design of roadway pavements, however, it has …

The influence of runway occupancy time and wake vortex separation requirements on runway throughput
… There has been limited new construction of runways due to land availability. One approach to increase capacity of existing runways is to reduce inter-arrival separations during the final approach phase of flight. This study evaluates two major elements influencing runway capacity; runway …

Estimation of Runway Throughput with Reduced Wake Separation, Runway Optimization, and Runway Occupancy Time Consideration
… This thesis focuses on selected US airport runways that could benefit from geometric optimization. The study aims to estimate ROT improvements through improved runway exit locations and the changes in runway throughput considering ROT constraint factors. The results of the thesis show that …

Urban Fashion
… opportunity to see and feel the clothes on the runways. For the private, the designers can work, show and display all in one building. The project divides itself into two worlds, the static vs. the dynamic. Both polarities are evident in the runways and in the gallery space. In a world where …

Utilizing Flight Data Monitoring at a Part 141 Flight School to Determine Predictors for Unstabilized Approaches and Go-arounds
… Instrument Approach Procedure Type, and Runways.</p> <p>Thirty-two percent of the 36,864 approaches evaluated were unstable. Aircraft Type, Approach Type, Approach Location, and Runways were found to be statistically significant predictors of approach stability. A Diamond DA-42 NG is 3.88 …

Evaluation of blunder detection by air traffic controllers using two different display types
… use of three and four closely spaced parallel runways. These operations would allow cost efficient capacity increases through concurrent use of already constructed runways and through the construction of additional runways at existing airports. Recent simulation studies have indicated that …

Home Range Analysis of the Montane Vole
… 1) An examination of nests, burrows, and runways, 2) A comparison of two methods of home range analysis--live trapping and radio-isotope tracing, and 3) A comparison of the home range of Microtus montanus with other species of Microtus as published in the literature.

FORMULATION OF DETECTION STRATEGIES IN IMAGES
… problem focuses on the accurate detection of runways by fusing Synthetic Vision System (SVS) and Enhanced Vision System (EVS) images. A novel procedure is developed to accurately detect runways and horizons and also enhance runway surrounding areas by fusing enhanced vision system (EVS) and …

Development of a Pavement Evaluation Method for Low-Volume Airfield Pavements
… for use only when the mission-essential runways are destroyed during an attack. Since ALRS pavements will only be used in contingency situations, an evaluation procedure is required to ensure that the pavements will support a limited number of operations.

Polymer and Concrete Composites in Industrial and Infrastructure Applications
… requires that emergency repair of military runways should be completed within 4 hours. In coordination with Luna Innovations Incorporated, a polymer concrete was developed by Luna for use as a rapid repair material for military runways to meet this requirement through its rapid heat curing. …

Air traffic flow management at airports : a unified optimization approach
… departures to be served; c) assigning flights to runways and determining their sequence; d) determining the gate-holding duration of departures and speedcontrol of arrivals; and e) routing flights to their assigned runway and onwards within the terminal area. In the first part, we propose an …

Application of aircraft sequencing to minimize departure delays at a busy airport
… in the order in which aircraft gain access to runways, while also improving efficiency by comparison to First Come First Served sequencing. The objective of the first algorithm is to minimize makespan, and that of the second to minimize delays. We then focus on a specific airport, which has …

A comparison of capacity and delay values between parallel and intersecting runway configurations at a major airport
… that would result if a "fanway" configuration of runways were utilized for arrival aircraft operations at a major airport. The Federal Aviation Administration's Delay Simulation Model was employed to determine capacity and delay values so that a conventional runway configuration could be compared …

Analysis of airside operations at Singapore Changi Airport
… congestion, building new infrastructure such as runways to improve capacity is an obvious solution but it is highly expensive and has a long lead time. In the short term, airport managers and operators have to learn to utilize current capacity more efficiently instead. This begins with the …

An investigation into the effect of waterblast on concrete and asphalt surfaces
… condition is critical to airport safety. Grooved runways are a standard feature because they permit drainage, allowing for safer landings by reducing the risk of hydroplaning. Hydroplaning occurs when water is pooling at the surface of the runway reducing severely the friction which dangerously …

Exploring Prototyping Tools for Interactive Fashion Design
… design, interactive garments on high fashion runways envision how people might use interactive technologies to enhance our clothing with new sensing and output capabilities. Researchers and fashion designers have since explored new interactive textiles that enable aesthetics-driven, …

Evaluation of avian hazards to aircraft at Dallas/Fort Worth International Airport
… largest US airports in total area – with seven runways between 1.6 and 2.5 miles long. At DFW, the 6 nautical mile boundary is too small to capture all air traffic below 3,000 feet. Air traffic radar tracking data suggests that arriving jets may enter the high-risk airspace below 3,000 feet AGL …
