Secure Grid-Based Computing with Social-Network Based Trust Management in the Semantic Web

The paper describes a new approach for treatment security issues in reconfigurable grids used for computing or communication, in particular, in the semantic web environment. The proposed strategy combines a convenient mathematical model, efficient combinatorial algorithms which are robust with respect to changes in the grid structure, and an efficient implementation. The mathematical model uses properties of weighted hypergraphs. Model flexibility enables to describe basic security relations ...

Shaped-Beam Pattern Synthesis of Linear Antenna Arrays with the Use of a Clonal Selection Algorithm

In this paper, the position-only, amplitude-only, and amplitude-phase synthesizes for the shaped-beam patterns of the linear antenna arrays have been achieved by using the clonal selection algorithm (CLONALG). The CLONALG is a relatively novel evolutionary optimization method based on the clonal selection principle of the human immune system. Numerical examples of the pencil, flat-topped, and cosecant patterns are given. Numerical results show that the CLONALG is capable of synthesizing the a...

Speech Analysis of Children with Developmental Dysphasia by Supervised Som

Tuckova and Zetocha study the connectivity between children's developmental dysphasia and assess the degree of perception and impairment of speech by using artificial neural networks and using knowledge of phonetics. A comparative voice analysis of healthy children and ill children is also performed.
