Career visual searchers such as radiologists and airport security screeners strive to conduct accurate visual searches, but despite extensive training, errors still occur. A key difference between searches in radiology and airport security is the structure of the search task: Radiologists typically scan a certain number of medical images (fixed objective), and airport security screeners typical...

With the high accident rate of civil aviation, medical resource inventory becomes more important for emergency management at the airport. Meanwhile, medical products usually are time-sensitive and short lifetime. Moreover, we find that the optimal medical resource inventory depends on multiple factors such as different risk preferences, the material shelf life and so on. Thus, it becomes very c...

In most languages, the quality of a speech synthesis system relates directly to the diversity of language domain. Each domain, such as sports, entertainments, etc., has its specific grammar structures. The grammar structure plays as an important role for analyzing the prosodic information of utterances in each domain. In this research, we will analyze characteristics of prosodic information of ...

Optimizing gate scheduling at airports is an old, but also a broad problem. The main purpose of this problem is to find an assignment for the flights arriving at and departing from an airport, while satisfying a set of constraints.A closer look at the literature in this research line shows thatin almost all studies airport gate processing time has been considered as a fix parameter. In this res...

Our goal is to produce high-quality symbolic descriptions from aerial scenes. We have chosen to work in the domain of large commercial airport complexes. Such scenes have a variety of features such as the transportation network, building structures, and mobile objects. This paper concentrates on detection and description of the transportation network (runways and taxiways). We illustrate the co...

Scheduled arriving aircraft demand may exceed airport arrival capacity when there is abnormal weather at an airport. In such situations, Federal Aviation Administration (FAA) institutes ground-delay programs (GDP) to delay flights before they depart from their originating airports. Efficient GDP planning depends on the accuracy of prediction of airport capacity and demand in the presence of unc...

Air traffic growth and especially hubs development cause new significant congestion and ground delays on major airports. Accurate models of airport traffic prediction can provide new tools to assist ground controllers in choosing the best taxiways and the most adapted holding points for aircraft. Such tools could also be used by airport designers to evaluate possible improvements on airport con...

Airport traffic consists of aircraft performing landing, takeoff and taxi procedures. It is controlled by air traffic controller (ATC). To safely perform this task he/she uses traffic surveillance equipment and voice communication systems to issue control clearances. One of the most important indicators of this process efficiency is practical airport capacity, which refers to the number of airc...
