The efficiency of oceanic flights is low due to limited navigational and communication equipment, congestion and airspace restrictions. The availability of Automated Dependent Surveillance-Broadcast (ADS-B) and other improvements provides opportunity for better strategic planning of trajectories. Transatlantic flights between US and Europe constitute one of the busiest oceanic airspace regions ...

Aircraft observations of wind and temperature are very important for upper air meteorology. In this article, the quality of the meteorological information of an Automatic Dependent Surveillance-Contract (ADS-C) message is assessed. The ADS-C messages broadcast by the aircraft are received at air traffic control centres for surveillance and airline control centres for general aircraft and dispat...

Standard automatic dependent surveillance broadcast (ADS-B) reception algorithms offer considerable performance at high signal-to-noise ratios (SNRs). However, the of ADS-B in applications can be problematic low SNRs and interference situations, as detecting decoding techniques may not perform correctly such circumstances. In addition, conventional error correction have limitations their abilit...

In the next generation modernization plan, automatic dependent surveillance-broadcast (ADS-B) system plays a pivotal role. However, ADS-B’s low level of security and its vulnerabilities have raised valid concerns. The main objectives this paper are to highlight limitations legacy ADS-B systems assess feasibility using Format-preserving (F), Feistel-based encryption with multiple implementation ...

The maneuvering characteristics and range of motion real aircraft are highly uncertain, which significantly increases the difficulty trajectory prediction. To solve problem that high-speed maneuvers excessive trajectories in airspace cause a decrease prediction accuracy to find out laws hidden large number trajectories, this paper proposes deep learning algorithm based on clustering spatiotempo...

Wang, Hao. M.S.A.A., Purdue University, May 2015. ADS-B Used in Improvement of Air Traffic Control. Major Professor: Dengfeng Sun. Automatic dependent surveillance – broadcast (ADS–B) is a central component of the NextGen air traffic control program. This surveillance technology can replace current secondary surveillance radars (SSR) and improve cockpit situational awareness. The service can im...

Not less than one hundred thousand Unmanned Aerial Vehicles (UAVs) are expected to perform flights simultaneously in Russia by 2035. The UAV fleet capacity triggers the development of systems for informational support, operating control and management (Unmanned Aircraft System Traffic Management (UTM) systems) similar that already manned aviation. challenges arising sphere civil aviation cannot...

This paper presents the recent development of the HTK broadcast news transcription system. Previously we have used data type specific modelling based on adapted Wall Street Journal trained HMMs. However, we are now using data for which no manual preclassification or segmentation is available and therefore automatic techniques are required and compatible acoustic modelling strategies must be ado...

Unrestrained growth is the hallmark of cancer, and disrupted cell-cycle regulation is, therefore, common. CDK4 is the key regulator of the G1–S transition. In complex with cyclin D, CDK4 phosphorylates retinoblastoma protein (Rb) and drives cell-cycle progression, a process inhibited by p16. The p16– CDK4–cyclin D–Rb is aberrant in themajority of cancers and is, thus, a logical target for antic...
