In this brief, a synthesis procedure for cellular neural networks (CNNs) with space-invariant cloning templates is proposed. The design algorithm is based on the use of the evolutionary algorithm of the particle swarm optimization (PSO) with the application to associative memories. The proposed synthesis procedure takes into account requirements in terms of(More)
Recently, surface mount technology is extensively used in the production of printed circuit boards due to the high level of miniaturization and to the increase of density in the electronic device integration. In such production process several defects could occur on the final electronic components, compromising its correct working. In this paper a(More)
In recent years, the requirement of compact devices caused an increasing use of Surface Mount Technology. This technology guarantees the reduction of the size of electronic packages by exploiting solder joint interconnection technology. Nevertheless, parameter variations can occur during the deposition and printing of the soldering paste on a board,(More)
In this paper a design procedure of Fuzzy Associative Memories containing fuzzy rules for bidimensional pattern segmentation in CNN-based systems is developed. A Fuzzy Necessity/Possibility Technique is considered for these memories to provide binary segmented images adequate to be stored into cellular neural networks for object matching analysis.(More)
In this paper an effective procedure that allows evaluating the dimensions of corrosive flaws on non-accessible pipes is presented. The method is based on the propagation of ultrasound waves, analyzing the informative content of echoes reflected by defects. The approach exploits the properties of the wavelet transform to represent signals by a reduced form.(More)
In this Letter, a method for recovering homogeneous upconversion coefficients (HUCs) in Er(3+)-doped glasses and erbium-activated devices is illustrated. It is based on a particle swarm optimization (PSO) approach. The HUCs are calculated on the basis of known values of optical gain evaluated in different pumping conditions. The obtained numerical results(More)
The use of powerline communications has attracted the attention of researchers increasingly, since this kind of data transmission allows to reduce the number of cables. This advantage is particularly appealing in railway, naval and aeronautical fields. In this paper a method to detect noisy events that occur in a powerline communication system in a naval(More)
