The performance expectations for printed circuit board surface finishes are greater than just solderability preservation. Historically, final finishes were designed solely to protect copper from oxidation prior to the soldering of components. Now the expectations are much greater; superior solderability, contact performance, wire bondability, corrosion resistance, and all this must be achieved at...
This paper presents a numerical model for the transport of the nuclear contamination and other passive particles in the ocean. As a consequence of the Chernobyl accident (April, 26th, 1986), the radioactive plume drift over many countries in Europe, and after some days, the Baltic Sea became the most contaminated ecosystem beyond the Soviet Union. Our Dispersion Model has been validated in this system...
A new methodology to learn descriptive linguistic Fuzzy Rule-based System Knowledge Bases from examples based on the combination of fuzzy clustering and evolutionary simultaneous rule selection and membership functions tuning is presented in this work. Fuzzy clustering is used to achieve a preliminary description of the data, in other words to obtain information on the definition of the linguistic...
This article is the last improved version of a previously published model (Toscano-Jimenez and Garcia-Tenorio, 2004) for the transport of the nuclear contamination and other passive particles in the ocean. Two interesting advances have been developed during last two years for the author's PhD thesis to be finished in the next months: (a) a suspended particulate matter (SPM) submodel, including erosion,...
This model is a improved version of a previously published two-scales model (Toscano-Jimenez and Garcia-Tenorio, 2004) and includes the transport of particles in three spatial scales: small (kilometres), medium (decades of Arm), and large (hundreds of km). A 3D dispersion model has been developed to analyse and simulate the dispersion of nuclear contaminants in marine ecosystems. This model is characterized...
