Simulation is the process of executing a model, that is a representation of a system with enough detail to describe it but not too excessive. This model has a set of entities an internal state, a set of input variable…

The paper provides a brief introduction into a relatively new discipline: artificial immune systems (AIS). These are computer systems exploiting the natural immune system (or NIS for brevity) metaphor: protect an organism against invaders. Hence, a natural field of applications…

The TTIGHa model has been developed to model
and predict the performance of parallel applications
run over heterogeneous architectures.
In addition, the task assignment algorithm was
implemented to MATEHa processors based on the
TTIGHa model.
This paper analyzes the assignment…

The need for privacy has become a major priority for both governments and civilians desiring protection from signal interception. Widespread use of personal communications devices has only increased demand for a level of security on previously insecure communications. This paper…

An Image Adaptive Watermarking method based on the
Discrete Wavelet Transform is presented in this paper.
The robustness and fidelity of the proposed method are
evaluated and the method is compared to state-of-the-art
watermarking techniques available in the literature. For

In this paper, we present a UML profile and a group of
UML patterns for documenting the component-andconnector
views of software architectures [8]. They facilitate the creation of the component and connector viewtype in any UML 2.0 tool with a…

Augmented marked graphs possess a special structure for modelling common resources as well as some desirable properties pertaining to liveness, boundedness, reversibility and conservativeness. This paper investigates the property-preserving composition of augmented marked graphs for the synthesis of distributed systems.…

Data quality is a research area strongly investigated during the 90’s. However, few companies in Argentina apply data quality methodologies or tools during the analysis, design or implementation phases of software development process. Developers generally use techniques to design systems…
