We propose a method to incrementally compute and use, during the concept formation, the relevance of a concept property. This relevance is computed through the account of the property correlation with other ones and it is used by the concept quality function in order to improve predictive accuracy. The proposed approach is analyzed concerning both the prediction power of the generated concepts ...

In this paper we consider a mathematical model for photoacoustic imaging which takes into account attenuation due to thermodynamic dissipation. The propagation of acoustic (compressional) waves is governed by a scalar wave equation coupled to the heat equation for the excess temperature. We seek to recover the initial acoustic profile from knowledge of acoustic measurements at the boundary. We ...

To explain human financial risk taking, economic, and finance theories typically refer to the mathematical properties of financial options, whereas psychological theories have emphasized the influence of emotion and cognition on choice. From a neuroscience perspective, choice emanates from a dynamic multicomponential process. Recent technological advances in neuroimaging have made it possible f...

catalytically graphitized electrospun carbon nanofibers adorned uniformly with fine nickel nanoparticles were successfully prepared. the procedure was based on the electrospinning technique and the use of nickel precursor to create both graphitized nanofibers and nickel nanoparticles under a relatively low-temperature heat treatment. the x-ray diffraction and raman results clearly proved cataly...

attention to character of relevance and proportion in qur'anic text plays a key role in correct understanding and secure interpretation of this scripture. achieveing to its conceptual grace and some of its secrets is required such attention. according to the statistical analysis in this study, without taking into account name of allah, god's attributes constitute nearly two percent of...

Ambient Intelligence and Affective Computing areas are working on trying to make interfaces more natural from the human side. Taking personal, device and system characteristics into account, adaptive interfaces might help to achieve a greater user satisfaction and it is expected the results can be enhanced when bearing user affectivity in mind. In this paper, an ontology that describes affectiv...
