We aim at developing autonomous micro-flyers capable of navigating within houses or small built environments. The severe weight and energy constraints of indoor flying platforms led us to take inspiration from flying insects for the selection of sensors, s ...
Determining safe aircraft trajectories that avoid hazardous weather regions and other aircraft while efficiently using the available airspace is an important problem. Although tactical weather forecast maps have been available, their use in automated aircr ...
The potential for identifying aircraft using one or more radar range profiles, in conjunction with a correlator, is investigated. Two types of filters are described which maximize the expected value of certain correlation peaks. The effectiveness of one ty ...
The problem of aircraft trajectory planning is formulated as a hybrid optimal control problem. The aircraft is modeled as a switched system, that is, a class of hybrid dynamical systems. The sequence of modes, the switching times, and the inputs for each m ...
Results from an extensive profile database analysis of JET density profiles in H-mode show that the density peaking factor n(e0)/ < n(e) > in JET H-modes increases as the effective collisionality v(eff) congruent to 10(-14) RZ(eff)n(e)/T-e(2) drops from si ...
Accurate trajectory prediction plays a fundamental role in advanced air traffic control operations, because it forms the basis for (among others) conflict detection and resolution schemes. It has been demonstrated that improved trajectory prediction accura ...

A review with some new data. Adding a vibration on a laminar jet for controlled break-up into monodisperse microcapsules is one among different extrusion technologies for encapsulation of cells, microbes, yeast, enzymes and liqs. (Poncelet, 1997). The vibr ...
This paper aims to contribute both to the ongoing process of scrape-off layer code-experiment and code-code benchmarking. Results are presented from SOLPS5 simulations of two high power JET H-modes with similar magnetic configuration, concentrating in the ...
We develop an accurate model for the arrival traffic dynamics in terminal airspace that takes into account the weather forecast and runway configuration changes. The planning of runway configuration switching subject to weather constraints is formulated as ...
