This paper focuses on the estimation of the non-measurable physical states of wastewater systems when nonlinear models with uncertainties describe the processes. The Activated Sludge Process (ASP), as the most commonly applied biological wastewater purification technique, attracts a great deal of attention from the research community. We developed for this(More)
In this paper, it is represented the performance of five level inverter fed by a photovoltaic PV generator and the induction motor is supplied by the inverter. In this context, the power converters are used for two main tasks. The first is a power DC-DC converter with MPPT technique to ensure a PV array to operate at maximum power point and ensure(More)
This paper studies the impact of wireless technologies on enterprises. A multitude of new paradigms and new software technologies have emerged from the web. E-business and e-manufacturing have really transformed concepts and practices in enterprises. Wireless technologies added new possibilities for these technologies, by this work we propose mmanufacturing(More)
The specification of the dynamic behaviour of reactive distributed systems must exhibit the structures of control and has to imply explicitly the relevant aspects of the distribution, such as the concurrency, the reactivity and the interaction between the entities. Among the most common reactive distributed systems we can cite industrial ones; distributed(More)
