We report here the fabrication of fiber chromatic dispersion compensators, along with the tests of those components in wavelength-division-multiplexed transmission at 10 Gb/s and an analysis of their performance by simulation. ...

An application of the multiple models adaptive control based on switching and tuning to a flexible transmission system is presented. This approach has been considered in order to assure high control performance in the presence of large load variation on th ...
Several approaches are described with the aim of producing near-field optical probes with improved properties. Focused ion beam milling allows the fabrication of small apertures in a controlled fashion, resulting in probes with excellent polarization prope ...
Investigates the use of embedded optical fiber Bragg gratings to measure strain near a stress concentration within a solid structure. Due to the nature of a stress concentration (i.e., the strong nonuniformity of the strain field), the assumption that the ...
We consider the transmission of variable bit rate (VBR) video over a network offering a guaranteed service such as ATM VBR or the guaranteed service of the IETF. The guaranteed service requires that the flow accepted by the network has to be conforming wit ...
We present a semi-automatic approach to solve occlu- sion in AR systems. Once the occluding objects have been segmented by hand in selected views called key-frames, the occluding boundary is computed automatically in the in- termediate views. To do that, t ...
This paper investigates the use of embedded optical fiber Bragg gratings to measure strain near a stress concentration within a solid structure. Due to the nature of a stress concentration (i.e. the strong non-uniformity of the strain field) the assumption ...
The Navier-Stokes equations for incompressible fluid are coupled to models of reduced complexity, such as Oseen and Stokes equations, and the transmission conditions are investigated. We carry out the mathematical analysis of the corresponding problem and ...
The transmission of binary information using chaotic switching, also called chaos shift keying is used. On the receiver side the information is extracted using a method that is not based on synchronization, but that directly tries to detect which chaotic s ...
Pulsations in the fetal heart propagate through the precordial vein and the ductus venosus but are normally not transmitted into the umbilical vein. Pulsations in the umbilical vein do occur, however, in early pregnancy and in pathological conditions. Such ...
