Weak Fairness Semantic Drawbacks in Java Multithreading,s kernel or application platforms. It is the aim of this paper to exemplify some subtle programming errors that may result from the process queuing and awaking policy, which corresponds to a weak fairness semantic and which has been chosen for implementing the monitor concept in this language.

This hierarchical scheduling model is a very interesting solution that allows us to have in the same system the best properties of the three policies: the high performance of EDF, the predictability of fixed priorities, and the

In this paper the two approaches are combined to maximize the advantages of both schemes. From EDF comes efficiency, from FP predictability. A system model is presented in which a relatively small number of high-integrity tasks

Implementing Reactive Systems with UML State Machines and Ada 2005, with object-oriented concepts. However, manual transformation of these expressive models to object-oriented languages is an error-prone process. Model-Driven Engineering approach advocates for an automatic process to translate models into high-level programing languages. This work deals with the co

BIP provides a language and a theory for incremental composition of heterogeneous components. As a full-size exercise, we deal here with the modeling of immediate and delayed data communica
