AT THE END OF THIS MONTH, THE ANTARCTIC TREATY SUMMIT IN WASHINGTON, DC, WILL CELEBRATE the 50th anniversary of an international agreement that has been centered around science, promoting cooperation to manage nearly 10% of Earth for peaceful purposes since 1 December 1959 (see www.atsummit50.aq). As the world moves toward negotiating effective policies related to climate change, lessons from t...

Decay resistance of out-of-service poles was investigated to evaluate their effectiveness against biodegradation for possible recycling of these poles for composite products. Decay resistance was related to creosote content and creosote distribution in poles with service durations of 5 and 25 years and also freshly treated poles. Weathering of the poles had caused reduction in creosote content ...

In this paper, first a new algorithm for pole assignment of closed-loop multi-variable controllable systems in a prescribed region of the z-plane is presented. Then, robust state feedback controllers are designed by implementing a neural fuzzy system for the placement of closed-loop poles of a controllable system in a prescribed region in the left-hand side of z-plane. A new method based on the...

This paper proposes a method to specify straightforwardly poles of controllers of strongly stable generalized predictive control(GPC) systems using symbolic computation software. Strongly stable control system is defined as a system having both of stable poles of closed loop systems and stable poles of controllers. That is, the system is stable even when feedback loop is cut by an accident. The...

Prony 's method is employed in spectral domain estimation to model epilepsy seizure from human's electroencephalograph (EEG).This method assumes that the original signal is a sum of damped complex exponential sinusoids. The method has the best frequency resolution compared to Auto Regression (AR) parametric methods. Modeling of the EEG Epilepsy signal is based on the poles of the signal. Comput...

Five experiments investigated how human adults use landmark arrays in the immediate environment to reorient relative to the local environment and relative to remote cities. Participants learned targets' directions with the presence of a proximal 4 poles forming a rectangular shape and an array of more distal poles forming a rectangular shape. Then participants were disoriented and pointed to ta...
