Is sedation by non-anaesthetists really safe?

I read with great interest the editorial recently published in the British Journal of Anaesthesia that questioned whether sedation by non-anaesthetists is really safe. The authors noted their ‘grave concerns’ about the emerging practice of non-anaesthetist administered propofol (NAAP) during electrophysiology procedures. I offer the following insights into this issue.

Transient stability analysis of electrical power systems using a neural network based on fuzzy ARTMAP

This work presents a methodology to analyze transient stability for electric energy systems using artificial neural networks based on fuzzy ARTMAP architecture. This architecture seeks exploring similarity with computational concepts on fuzzy set theory and ART (Adaptive Resonance Theory) neural network. The ART architectures show plasticity and stability characteristics, which are essential qualities to provide the training and to execute the analysis. Therefore, it is used a very fast training, when compared to the conventional backpropagation algorithm formulation. Consequently, the analysis becomes more competitive, compared to the principal methods found in the specialized literature. Results considering a system composed of 45 buses, 72 transmission lines and 10 synchronous machines are presented. © 2003 IEEE.
