In this communication, we present a theoretical analysis, design, and fabrication of limited-diffractive planar Bessel beam launcher, that exhibits zeroth-order profile in the transverse electric field component with respect to z-propagation axis. The launcher is designed by synthesizing finite zeroth-order, first kind Hankel aperture distribution, polarized along fixed polarization unit vector...

UNLABELLED Emerging web-services technology allows interoperability between multiple distributed architectures. Here, we present REMORA, a web server implemented according to the BioMoby web-service specifications, providing life science researchers with an easy-to-use workflow generator and launcher, a repository of predefined workflows and a survey system.

A possible cause for the accident of Ariane 5 in its maiden flight has been associated with the mishandling of an abnormal situation (known as an exception) that had occurred in the embedded software of the launcher.That is, after an exception behaviour was detected, the inappropriate corrective action taken by the software made the vehicle to veer off its flight path leading to the structural ...

Abstract In the last decade, rapid and successful development of reusable launch systems such as SpaceX’ Falcon 9 demonstrated both operational feasibility launchers their economic viability. The objective recovering a launcher or launcher’s booster requires to safely return vehicle from orbital sub-orbital conditions soft landing. To increase reusability, decrease turnaround time reduce costs,...

Sensor failure detection and identification has been considered as an important issue, particularly when the measurements from sensors are used in the feedback loop of a control law. Kalman filters and Luenberger observers have been widely used to generate signal redundancy by means of state estimation. Dedicated observer scheme and generalized observer scheme are the older methods available fo...

RF heating and current drive is an essential component in most magnetic fusion devices, including ITER. Recent results obtained with high harmonic fast wave (HHFW) heating and current drive (CD) on NSTX strongly support the hypothesis that the onset of perpendicular fast wave propagation right at or very near the launcher is a primary cause for reduced core heating efficiency at long wavelength...
