Fiber dispersion coupled with chirp parameter of the emitting laser impacts the optical transmission system performance. Fiber dispersion causes the propagating pulses to spread and overlap, and the chirp parameter produces a wavelength shift arising from the intensity variation of the directly modulated laser (DML). For optical transmission systems,(More)
Random Forests (RF) and Boosting are two of the most successful supervised learning paradigms for automatic classification. In this work we propose to combine both strategies in order to exploit their strengths while simultaneously solving some of their drawbacks, especially when applied to high-dimensional and noisy classification tasks. More specifically,(More)
This paper reports the development of a fast separation method employing capillary zone electrophoresis for the simultaneous determination of hippuric acid, mandelic acid, and creatinine in samples of urine using a coated capillary. The background electrolyte was composed of 10 mmol L-1 tris(hydroxymethyl)aminomethane and 30 mmol L-1 2-hydroxy-isobutyric(More)
We present here an all-integrated ETDM 40 Gbit/s optoelectronic transmitter module, which has been developed by the French RNRT ERMIONE consortium. This transmitter integrates the final three high speed functions - namely, the electrical multiplexer, the driver and the electro-absorption modulator - in a single compact and low-cost module. This device has(More)
The advances of the past decades in Mobile Robots enable achievement of increasingly complex tasks and require a high amount of information in the environment. In this context, the vision sensors are widely spread tools and able to capture a large set of data from the environment without the need for physical contact, and with very reasonable cost of(More)
