Grid connected wind energy conversion systems (WECS) present interesting control demands, due to the intrinsic nonlinear characteristics of windmills and electric generators. In this paper a direct adaptive control strategy for WECS control is proposed. It is based on the combination of two control actions: a radial basis zfunction network-based adaptive(More)
In this article a stochastic model for point events expected in the output image of scientific CCDs is derived. This kind of events are typical in CCD systems dedicated to particle detection, such as DAMIC and CONNIE. The model includes the randomness of the charge movement in the silicon and the noise at the readout stage providing the base for an optimal(More)
Fully depleted thick CCDs have been designed for infrared astronomy, but their low read-out noise of the order of &#x2248;2e<sup>-</sup> and their considerable mass of &#x2248;5.2 gr, allows novel uses for them in low energy threshold particle detection applications, such as the CONNIE and DAMIC experiments. For both experiments, a reduction of the CCD(More)
We present direct detection constraints on the absorption of hidden-photon dark matter with particle masses in the range 1.2-30  eV c^{-2} with the DAMIC experiment at SNOLAB. Under the assumption that the local dark matter is entirely constituted of hidden photons, the sensitivity to the kinetic mixing parameter κ is competitive with constraints from solar(More)
The readout noise for Charge-Coupled Devices (CCDs) has been the main limitation when using these detectors for measuring small amplitude signals. A readout system for a very low noise scientific CCD is presented in this paper. The Skipper CCD architecture, and its advantages for low noise applications are discussed. A technique for obtaining sub-electron(More)
The current paper studies how processor failures affect the dataflow of the Level 1 Trigger in the BTeV experiment proposed to run at Fermilab's Tevatron. The failure analysis is crucial for a system with over 2500 processing nodes and a number of storage units and communication links of the same order of magnitude. The failure analysis is based on models(More)
The production of polymeric complexes in many active drugs with reticulated povidone increased dissolved component percentage. In this work made use a coevaporation technique. Complex formation has been tested by X Ray Diffractometry and Differential Scanning Calorimetry. The percentage of dissolution was determined to the USP XXIII Edition methodology. As(More)
