The topology and the resistance of local-world networks are investigated. Different strategies of the local-world forming are analyzed. The degree distribution and the correlation type in considered networks are defined. The resistance of local-world networks to random failures and targeted attacks is considered. Keywords: complex networks, scale-free networks, local-world networks, degree distribution, correlated networks, random failures, targeted attacks, resistance of networks.

The article is about a technique witch helps to describe the process of software development. The technique is based on the idea of stage ranging according to a criterion of material and information streams. It is shown that stages of creation correspond to universum functions of management. The conclusion is that universum approach increases efficiency and the quality of any development

54. Perturbation functions in geometric modeling [№4 за 2009 год]

Transformations of a geometric objects are described for set-theoretic operations, projections, offsetting, and metamorphosis. A binary relation such as collision detection is also described. This approach supports combinations of representational styles, including constructive geometry, sweeping, twisting, deformable and other animated objects. Interactive modification of the function model with fast visualization lets us provide both the interactivity and any required level of detail leading to photo-realistic appearance of the resulting shapes.

55. Identification of the technical condition on the basis of neural network models [№4 за 2009 год]
