GA-Based Optimization of Sigma-Delta Modulators for Wireless Transceivers

Over-sampling sigma-delta Analog-to-Digital Converters ADCs are one of the key building blocks of state of the art wireless transceivers. In sigma-delta modulator design, the scaling coefficients determine the peak signal-to-noise ratio. Therefore, selecting the optimum value of the coefficient is very important. To this end, this paper addresses the design...

Thinking -- Or Feeling -- Like A Computer

So an unknown billionaire named Jeffrey E. Epstein has spent millions trying to develop a thinking and feeling computer. But winds up in jail instead. This sounds eerily like a wish to build a HAL 9000 computer that was the central character of Arthur C. Clarke's science...

Biometric IDs for African penguins?

University of Bristol researchers have developed a non-intrusive visual surveillance system for wildlife habitats. They've used their system to monitor the behavior of 20,000 African penguins on Robben Island in South Africa. By definition, conventional tagging techniques can only monitor animals which have been tagged. On the contrary, the 'Penguin...

Silicon chips for optical quantum computing

UK researchers at Bristol University have shown that it is possible to control single photons on a silicon chip. The team developed 'the world's smallest optical controlled-NOT gate -- the building block of a quantum computer.' As said the lead researcher, 'This is a crucial step towards a future optical...

Liquid drops defying gravity

Researchers at the University of Bristol, UK, have shown that droplets of liquid can travel uphill when placed on a vertically vibrating inclined plate. 'In fact, if the plate vibrates at the right rate, the droplets will always travel counter-intuitively up the incline.' This very interesting discovery will not change...
