This paper presents a design approach for a fuzzy cellular automaton based on an inverse entropy optimization principle. The cells of the automaton are characterized by two state variables computed by dynamic TSK fuzzy systems. The state variables of the cells are understood as spatial information sources so that the entropy of the binary sequences produced by the cells is maximized in a given instant...
This article presents the application of a new concept for collision detection into robotic virtual environments. This concept, named Semantic Coherence, aims to make an earlier evaluation of the virtual environment as a mean to foresee true cases of non-collision or situations of major probabilities of collision. The proposed approach was implemented in two case study environments: (i) an isolated...
Emotions play a key role in any purchasing process even more when it is done through web portals. In this paper, we present a fuzzy-logic based system aimed to generate emotions for a virtual seller or avatar. The 3D avatar is integrated within the e-Zoco e-commerce portal and its behaviour depends on the product search results. Moreover, the mood of the avatar not only depend on the products that...
In this article, textile electrodes and semiconductor thin film piezoresistive sensors on plastic substrates were manufactured and fabricated with CMOS processes, respectively. An armband made of plain weave fabric, integrating embroidery textile electrodes of stainless steel (SS) and elastics to conform to human forearms were manufactured. The textile electrodes with an area of 1cm2 were made of...
One of the environmental effects of wind farms is that wind turbines act as scattering devices of the electromagnetic RF waves and thus, may cause interferences to different telecommunication services around them. To carry on with a previous work [4], the model of the nacelle and the wind turbine is shown and validated. Finally, a wideband terrain-sensitive channel response model has been developed...
E-commerce became very popular in recent years because of the great success achieved by some applications such as online auctions. However, currently the trend is that users of these portals execute more transactions in direct shopping than in online auctions and, probably because of the beginning of many of such portals as auctioning sites, their effectiveness decreases when searching for products...
