Security of virtual entities

The concepts of basic virtual entity and derived virtual entity are presented. Their quality characteristics are defined in the context of multiple accessing by heterogeneous target group members. The development conditions of derived entities are established. For collections of basic virtual entities and derived entities, are constructed and implemented algorithms to ensure and increase the level of security in the virtual environment. To implement a complete set of virtual entities, measurements of the security level are performed, using a special metric built.

Control of Metrics Design on Mobile Quality Application

Abstract Mobile applications structures are presented and their quality characteristics. The development cycle for m-applications is analyzed in the context of ensuring TQM requirements. A system of quality indicators of m-applications is designed and properties of these indicators are analyzed in relation to the operationality and representation of provided results. Practical arrangements for checking the metric for general classes of m-applications are established. The considered experiments come to emphasize the need to use metrics and the aggregate quality indicator.

Assigning Weights for Quality Software Metrics Aggregation

Abstract The description of quality software metrics is presented. Based on a set of quality characteristics, specialized and application oriented characteristics systems are built. For each characteristic there are countless level estimation models, from which a significant one is debated. A model in which the codomain is between [0,1] is selected for each characteristic correlated with a high level of orthogonality in relation to other characteristics that are part of the system. An aggregate indicator with the codomain between [0,1] is built using weights that create a more comprehensive overview of software quality. The importance of defining techniques for weights calculation is presented. The properties obtained for the weights are analyzed using different techniques.
