This paper presents a model of an airport apron that has been developed in order to determine a dynamical model for aircraft travel time in this area. This model is intended for future systems that will support automated routing and taxiing of aircraft in airport taxiways. The apron model proposed keeps into account the main issues related to the aircraft ground movements, such as aircraft conf...

PURPOSE The purpose of this study was to determine the facial movement characteristics of patients who underwent orthognathic surgery. The specific aims were to determine the presurgery versus postsurgery differences in facial movements; to determine whether the presurgery facial movements were similar among patients with different dentofacial deformities; and to determine whether patients have...
