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.…

An ubiquitous computation environment has as
presupposed that the computation is in all equipment
and devices, and these are interacting between itself
and with the people. The connection between objects
and human beings is instantaneous, when these enter
in the…
