FAA’s NextGen program aims to increase the capacity of the national airspace, while ensuring the safety of aircraft. This paper provides a distributed merging and spacing algorithm that maximizes the throughput at the terminal phase of flight, using information communicated between neighboring aircraft through the ADS-B framework. Aircraft belonging to a mixed fleet negotiate with each other an...

R. Pantophlet (ed.), HIV Glycans in Infection and Immunity, DOI 10.1007/978-1-4614-8872-9_6, © Springer Science+Business Media New York 2014 Abstract HIV has evolved a number of strong defense mechanisms, including extensive glycosylation of its surface envelope glycoprotein, to evade host immune responses. Nevertheless, the discovery of a series of glycan-dependent broadly neutralizing antibod...

In this paper, we describe adaptation techniques for a hierarchically organized multi-agent-system (MAS) applied to production control of complex job shops. The system architecture of the production control system is based on three different control layers. The mid layer implements a distributed shifting bottleneck type solution procedure. The shifting bottleneck heuristic decomposes the overal...

Multiple 1090ES responsive signals may be overlapped in the receiver systems on the ground. At the same time, 1090ES respond signals may be interfered by A/C replies with the same carrier frequency. To address these problems, firstly, principle component analysis (PCA) is employed to pre-whiten the observed signals in order to reduce the relevance between signals. Then extended projection algor...

In this study, vibration cutting has been applied to machining of a novel material, NiTi based shape memory alloy (SMA), using a commercial ultrasonic piezoelectric transducer to vibrate an ISO insert CCMT geometry cutting tool. The effect of vibration in turning process was characterized by investigating the surface roughness of workpiece and surface quality assessment of machined surface usin...

The Small Aircraft Transportation System (SATS) is a partnership among various organizations including NASA, the FAA, US aviation industry, state and local aviation officials, and universities. The program objectives are intend to reduce travel times by providing high-speed, safe travel alternatives by making use of small aircraft and underused small airports throughout the nation. A major comp...

Web content mining opens up the possibility to use data presented in web pages for the discovery of interesting and useful patterns. Our web mining tool, FBL (Filtered Bayesian Learning), performs a two stage process: first it analyzes data present in a web page, and then, using information about the data dependencies encountered, it performs the mining phase based on bayesian learning. The Näi...

How and when eukaryotic cells make the irrevocable commitment to divide remain central questions in the cell-cycle field. Parallel studies in yeast and mammalian cells seemed to suggest analogous control mechanisms operating during the G1 phase—at Start or the restriction (R) point, respectively—to integrate nutritional and developmental signals and decide between distinct cell fates: cell-cycl...

Detection of smoke plumes using lidar provides many advantages with respect to passive methods of fire surveillance. However, the great sensitivity of the method results in the detection of many spurious signals. Correspondingly, the automatic lidar surveillance must be provided with effective algorithms of separation of the smoke-plume signatures from irrelevant signals. The paper discusses a ...

Today’s National Airspace System (NAS) is managed using an aging surveillance radar system. The radar technology is not adequate to sustain the support of aviation growth and cannot be adapted to use 21st century technologies Therefore, FAA has begun to implement the Next Generation Air Transportation System (NextGen) that would transform today’s aviation and ensure increased safety and capacit...
