In this paper we present a survey of a recently developed approach to specifying, modelling, exploring and designing parallel media-processing and wireless communications platforms and platform instances. More specifically, we take a closer look at the notions of Y-chart and Abstraction Pyramid. The methodology and approach that is reviewed in this paper uses these notions and focuses on the sy...

Classiication is one of the data mining problems receiving great attention recently in the database community. This paper presents an approach to discover symbolic classiication rules using neural networks. Neural networks have not been thought suited for data mining because how the classiications were made is not explicitly stated as symbolic rules that are suitable for veriication or interpre...

in this work the kinetic data demanded for kinetic modeling were obtained in temperatures 350, 400, 450 and 500 oc by conducting experimentations on a fe-cr nanocatalyst prepared from a novel method and a commercial fe-cr-cu one. the collected data were subjected to kinetic modeling by using two models derived from redox and associative mechanisms as well as an empirical one. the coefficients o...

the activation of carbon monoxide by oxygen on mg(100) surface has been investigated by x-ray photoelectron spectroscopy (xps). carbon monoxide is only weakly adsorbed (dispersion-type forces) on a magnesium surface. the xps result has shown that the dissociation of carbon monoxide leading to the formation of a metastable surface carbonate species occurs through the participation of an oxygen s...

the kinetic of fischer-tropsch synthesis over a co-precipitated fe-ce catalyst was investigated in a fixed bed micro reactor. experimental conditions were varied as follow: reaction pressure 1-15bar, h¬¬¬2/co feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°c. 4 models according to the langmuir-hinshelwood-hougen-watson (lhhw) type rate equation were der...

Cognitive Architectures (CAs) are the core of artificial cognitive systems. A CA is supposed to specify the human brain at a level of abstraction suitable for explaining how it achieves the functions of the mind. Over the years a number of distinct CAs have been proposed by different authors and their limitations and potentials were investigated. These CAs are usually classified as symbolic and...

the symbolic cultural order becomes manifest through language in the case of texts and narratives and through images in the case of art. knowledge of the elements that compose the symbolic order is an essential analytical tool, above all for comparative studies of art, literature and religion. in this way, many of the symbolic references that exist in each culture can be illuminated by examples...

Schiff base complexes of transition metals are of particular interest to inorganic chemists because of their structural, spectral and chemical properties, which are often strongly dependant on the nature of the ligand structure. Large number of metal (II) complexes with Schiff-base ligands has been extensively studied for their interesting structural specialties, applications and properties. Th...
