A model for discharge lamp based on lamp electrical conductance is proposed. Physical assumptions are used to obtain this model. The model allows simulating lamp behavior at different frequencies and delivered power levels. The model has been verified using a high pressure sodium lamp supplied at 50 and 100kHz
In last years, NiCd and NiMH technologies have settled in the market of medium/high capacity batteries. Fast-charge is very interesting in different applications (communications systems, electric vehicles, low-earth-orbit spacecrafts) in order to minimizing charge time. The problem is that high currents involved in fast-charge process affect battery… (More)
This work shows the design of a low-cost, portable instrument for amperometric biosensors, which measures the faradaic currents originated by the electronic interchanges between a specific substance and a biological recognition system, present on an electrode and kept at an appropriate potential. The final objective is to obtain a direct relationship… (More)
This paper proposes a model for HID lamps based on equivalent conductance. Model equations have been solved at low and high frequency using a PSPICE. Model results show fairly agreement with experimental data.
The goal of this paper is to study how the vapour pressure and the electrical characteristics of a high pressure sodium (HPS) lamp are affected by acoustic resonances to determine if some of those parameters can be used as acoustic resonances detector.
This paper describes an automatic acoustic resonance detection workbench for HID lamps controlled by computer. The control program is made with LabVIEW. The detection method is based on the projection of discharge arc. Relative intensity measurements at different points of projections are made and analyzed statistically to detect acoustic resonances.… (More)
Fiber optic sensing for chemical analysis is a growing technology, since it offers several advantages, as analysis can be done "in situ" in real time, the sensing techniques do not disturb the process, so the sample size can be extremely small and the sensing locations can be in remote areas. Fluorescence measurements are particularly well-suited for… (More)
