paper presents the advances of a research using a combination of recurrent and feed-forward neural networks for long term prediction of chaotic time series. It is known that point-to-point, long term prediction for chaotic time series is not possible; however, in this research we are looking for ways to build dynamical systems using artificial neural network, that contain the same characteristi...

The 8th Technicon International Congress, was held from the 12th-14th December, at the Wembley Conference Centre, London, UK. It is over seven years since such an event was last held in the United Kingdom and over the three days of the congress a wide range of analytical topics covering both industrial and clinical chemistry were covered in the various sessions. In addition the delegates were a...

Despite recent advances in automatic speech recognition (ASR) technology, successful ASR applications tend to be limited to telephony, command-and-control functions, head-worn microphones, small vocabularies, and/or simple grammars. Recording and processing spontaneous, human-to-human conversations in natural settings is a far more challenging task. Face-to-face meetings are not only challengin...

exhibited their new instruments in 1400 booths. Of the 900 papers presented at the conference, the following from the symposium on 'Process analysers' dealt with automated stream analysis for process control. Gibbon and Hackett [1] described the use of automated research-quality gas chromatographs to analyse the effluents from bench-scale coal gasification or liquefaction equipment. The high sp...

period during which the valve is either on or off and the rate of pumping. An air supply from a cylinder or air line at a pressure of a few kilograms per square centimetre is required. The device is very flexible, the rate of flow can be quickly adjusted by altering the timer settings or changing the syringe size or stroke and it will work for long periods without failure. It is not suitable fo...
