This paper considers nonparametric inference for duration times of two successive events. Since the second duration process becomes observable only if the first event has occurred, the length of the first duration affects the probability of the second duration being censored. Dependent censoring arises if the two duration times are correlated, which is often the case. Standard approaches to thi...

In this paper, we introduce the octagon metric as a useful distance metric for the interactive visualization of large–scale terrain data. Based on recursive bisection triangle meshes, this metric automatically ensures valid distance–dependent triangulations without cracks or T–junctions. We will show how the octagon metric can be used for view–dependent refinement at little computational cost a...

Automatic Dependent Surveillance-Broadcast (ADS-B) system provides significant improvements in air traffic control such as optimal routing non-radar environments with a new level of safety and efficiency. The ADS-B is being installed many aircrafts recent year. equipped aircraft broadcasts the information to nearby ground stations either once or twice per second. Because open channel communicat...

Automatic dependent surveillance-broadcast (ADS-B) is a very important communication and surveillance technology in air traffic control (ATC). In the future, more satellites will carry out ADS-B to perform global coverage. order make full use of resources satellite, this paper proposes solution for satellite three-axis attitude determination using receiver. The principle ADS-B-based presented f...

GPS-Squitter is a system concept that merges the capabilities of Automatic Dependent Surveillance (ADS) and the Mode S beacon radar. The result is an ktegraurd concept for seamless surveillance and data link that permits equipped aimaft to participate in A D S or beacon ground envinwlments. This offers many possibilities for transition from beacon to ADS-based surveillance. This paper briefly d...
