2. SIMOO-RT : an object-oriented framework for the development of real-time industrial automation systems
This paper presents SIMOO-RT, an object-oriented framework designed to support the whole development cycle of real-time industrial automation systems. It is based on the concept of distributed active objects, which are autonomous execution entities that have their own thread of control, and that interact with each other by means of remote methods invocation.

6. Generation of a family of software products with components based architecture / Geração de famílias de produtos de software com arquitetura baseada em componentes.
Adaptation of a specific software product line process is described. The adapted process aims to be agile, minimising rework for feature design and development activities and facilitating applications engineering. The domain engineering phase is iterative and incremental, using a component-based architecture. Applications are generated by an application gene

9. Modelagem e análise de sistemas supervisórios híbridos. / Modeling and analysis of hybrid supervisory systems.
Hybrid Supervisory Systems can be described as control systems with states that are represented by both discrete and continuous variables. Their dynamics are function of time and depend also on the occurrence of discrete events. The development of Hybrid Supervisory Systems can be divided in two phases. In the 1st Phase, a prototype-model for the Supervisory

12. Preferred negative geotactic orientation in mobile cells: Tetrahymena results.
For the protozoan species Tetrahymena a series of airplane experiments are reported, which varied gravity as an active laboratory parameter and tested for corresponding changes in geotaxic orientation of single cells. The airplane achieved alternating periods of low (0.01 g) and high (1.8 g; g = 980 cm/s) gravity by flying repeated Keplerian parabolas. The e
