Advances in marine ecotoxicology: laboratory tests versus field assessment data on sediment quality studies
(Universidad Autónoma de Baja California, 2000-03)
Ecotoxicology is concerned with describing and predicting the behaviour of substances in the environment and the response of biological systems, and ultimately with assessing the risks associated with emissions. These ...

An AER Contrast Retina with On-Chip Calibration
(IEEE Computer Society, 2007)
We present a contrast retina microchip that provides its output as an AER (Address Event Representation) stream. Contrast is computed as the ratio between pixel photocurrent and a local average between neighboring pixels ...

Low-voltage CMOS log-companding techniques for audio applications
(Springer, 2004)
This paper presents a collection of novel current-mode circuit techniques for the integration of very low-voltage (down to 1 V) low-power (few hundreds of μA) complete SoCs in CMOS technologies. The new design proposal is ...

An Approach to Reduce the Cost of Evaluation in Evolutionary Learning
(Springer, 2005)
The supervised learning methods applying evolutionary al gorithms to generate knowledge model are extremely costly in time and space. Fundamentally, this high computational cost is fundamentally due to the evaluation ...
