This paper introduces an ARCH model (exponential ARCH) that (1) allows correlation between returns and volatility innovations (an important feature of stock market volatility changes), (2) eliminates the need for inequal...

A predictive in vitro-invivo correlation (IVIVC) can empower in vitro dissolution as a surrogate for in vivo bioavailability / bioequivalence. IVIVCs can decrease regulatory burden by decreasing the number of biostudies ...

Mobile robot's navigation and obstacle avoidance in an unknown and static environment is analyzed in this paper. From the guidance of position sensors, artificial neural network (ANN) based controllers settle the desired...

This paper presents a parallel architecture for a radial basis function (RBF) neural network used for pattern recognition. This architecture allows defining sub-networks which can be activated sequentially. It can be use...

Vision based applications are present anywhere. A special market is industry, allowing to improve product quality and to reduce manufacturing costs. The vision systems applied to industries are known as machine vision sy...

Lucilia nitens is a herb used in folk medicine for treating diarrhoea and popularly called in Brazil "erva-pombinha". Aiming to expand the knowledge on this medicinal plant, this work has dealt with anatomical analysis o...

This study evaluated the effect of Cordia verbenacea essential oil (CV) and glycolic acid 70 % (GA), isolated and associated, on Wistar rats back skin. A base gel was added to 2 % of CV and/or 10 % of GA, thus forming ...
