VDL-based iconic co-annotation in crisis management

2014 International Conference on Collaboration Technologies and Systems (CTS), 2014
Crisis management is typical collaborative work which requires multi types of actors to cooperate in decision making. Crisis Clever System (CCS) is a decision making environment based on emergency experience feedback and provides situation base for later cases.

Comparison of VDL modes in the aeronautical telecommunications network

Proceedings, IEEE Aerospace Conference, 2003
VHF digital link (VDL) has been identified as a method of communication between aircraft and ground stations in the aeronautical telecommunications network (ATN). Three different modes of VDL have been suggested for implementation. Simulations were conducted to compare the data transfer capabilities of VDL modes 2, 3, and 4.

Evaluation of VDL modes in the en-route domain

The 23rd Digital Avionics Systems Conference (IEEE Cat. No.04CH37576), 2005
In this paper we investigate the performance of VDL modes 2,3, and 4 in the en-route domain by simulating mobile aircraft that dynamically establish and disconnect links to the ground station. In simulation one, the aircraft modeled are within a single sector of airspace which is the current boundary for en-route aircraft communication.

Definition Einer Programmanalysemaschine in VDL

1978
Bevor ein Programm optimiert werden kann, mus zur Ubersetzungszeit Information bestimmt und gesammelt werden. Die Techniken, die zur Bestimmung der Optimierungsinformation verwendet werden, gehen meist von der Darstellung des Programmes als Flusgraph aus [U 75, K 73, AC 76].

VDL Mode 4/STDMA-a CNS data link

15th DASC. AIAA/IEEE Digital Avionics Systems Conference, 2002
At its tenth Air Navigation Conference (1991), the ICAO endorsed the so-called Communication, Navigation, Surveillance/Air Traffic Management concept, CNS/ATM. This concept envisages the use of data link communications, satellite navigation and automatic dependent surveillance (ADS). The Swedish Civil Aviation Administration (SCAA) has been involved in

A collisi on avoidance concept for VDL mode 2

2007 IEEE/AIAA 26th Digital Avionics Systems Conference, 2007
The FAA is currently investigating the migration path to data-enabled digital air traffic services using VDL mode 2. Under certain loading conditions, simulations have shown that VDL mode 2 cannot meet future delay requirements with more than a few dozen aircraft per channel.

An Improved Long Transmission Protocol for VDL Mode 4

2006 International Conference on Wireless Communications, Networking and Mobile Computing, 2006
An improved long transmission protocol for very high frequency (VHF) digital link (VDL) mode 4 in aeronautical telecommunications network (ATN) is proposed, which includes a combined transmission scheme and a retransmission mechanism. In the combined transmission scheme, control messages can be piggybacked in conflict-free message transmission, and ...

Some VDL applications for helicopter safety and efficient operation

Proceedings. The 21st Digital Avionics Systems Conference, 2003
A new air-to-air surveillance system that consists of Global Positioning System (GPS) based position sensor, VHF data link (VDL) and cockpit display for traffic information (CDTI) had been developed. The result of the flight test showed great improvement on situational awareness of a surrounding traffic, i.e. "see and avoid" capability.

Commande en langage naturel d'agents VDL

2005
L'objectif de cet article est de présenter une architecture de traitement automatique des langues (TAL) pour la plate-forme d'agents VDL développée au LIP6. Le système de TAL est composé d'un lemmatiseur-étiqueteur, d'un analyseur syntaxique et d'un analyseur sémantique. L'analyse sémantique s'appuie sur une ontologie de tâche définie pour chaque agent
