Cost-based XML query optimization calls for accurate estimation of the selectivity of path expressions. Some other interactive and internet applications can also benefit from such estimations. While there are a number of estimation techniques proposed in the literature, almost none of them has any guarantee on the estimation accuracy within a given space limit. In addition, most of them assume ...

An 80 x 60 pixels arbitrated address-event imager has been designed and fabricated in a 0.6 μm CMOS process. The value of the intensity is inversely proportional to the inter-spike interval and the read-out of each spike is initiated by the pixel. The available output bandwidth is allocated according to the pixel's demand, favoring brighter pixels and minimizing power consumption. The imager ha...
