In this paper, we propose two new methods for open-domain question answering. First, we use knowledge resembling “common sense” for question answering purposes. For example, the length of a runway in an airport must be a few kilometers, but a few centimeters. In practice, we use specific types of information latent in document collections to verify the correctness of each answer candidate. Seco...

Aircraft departing from an airport are subject to numerous constraints while scheduling departure times. These constraints include wake-separation constraints for successive departures, miles-in-trail separation for aircraft bound for the same departure fixes, and time-window or prioritization constraints for individual flights. Besides these, emissions as well as increased fuel consumption due...

This paper studies the multiple runway aircraft landing problem. The aim is to schedule arriving aircraft to available runways at the airport. Landing times lie within predefined time windows and safety separation constraints between two successive landings must be satisfied. We propose a new approach for solving the problem. The method is based on an approximation of the separation time matrix...

In this paper, an airport departure scheduling tool for aircraft is presented based on constraint satisfaction techniques. Airports are getting more and more congested with the available runway configuration as one of the most constraining factors. A possibility to alleviate this congestion is to assist controllers in the planning and scheduling process of aircraft. The prototype presented here...

After years of use, there’s oil loss on the asphalt pavement. bond strength aggregate decreases. Loose threshing is serious. In order to improve pavement performance, Extend service life pavement, Improve safety aircraft operation. we test AC-20 modified mixture runway Da Lian Airport from many factors, including raw materials, admixtures, gradation design, optimum ratio stone, then find best w...

With increasing levels of air traffic making effective use of limited airport capacity is obviously important. This paper reports on an investigation undertaken by National Air Traffic Services in the UK into improving runway utilisation at London Heathrow. This investigation centred on developing an algorithm for improving the scheduling of aircraft waiting to land. The heuristic algorithm dev...

After years of use, there’s oil loss on the asphalt pavement. bond strength aggregate decreases. Loose threshing is serious. In order to improve pavement performance, Extend service life pavement, Improve safety aircraft operation. We test AC-20 modified mixture taxiway and runway Chang Sha Airport from many factors, including raw materials, admixtures, gradation design, optimum ratio stone, th...

The ability to detect and locate runways/taxiways and obstacles in images captured using on-board sensors is an essential first step in the automation of low-altitude flight, landing, takeoff, and taxiing phase of aircraft navigation. Automation of these functions under different weather and lighting situations, can be facilitated by using sensors of different modalities. An aircraft-based Synt...

An integrated approach based on machine learning and data augmentation techniques has been developed in order to predict the stiffness modulus of asphalt concrete layer an airport runway, from acquired with a heavy weight deflectometer (HWD). The predictive model relies shallow neural network (SNN) trained results backcalculation, by means method can produce estimations even at runway points no...

Over the years, Global Reporting Format (GRF) was first major change in approach to evaluate runway conditions. The greatest impulse for this new regulation were incidents and accidents related mainly excursions that occurred because of unfavorable weather conditions, when not only aircraft different airport facilities but also human health lives suffered. To better understand these changes, th...
