Unified specification of control and data flow

چکیده
Many signal processing systems use event driven mechanisms typically based on nite state machines (FSMs) to control the operation of computationally intensive (data ow) parts. The state machines in turn are often fueled by external inputs as well as by feedback from the signal processing portions of the system. Packet-based transmission systems are a good example for such a close interaction between data and control ow. For an e cient design ow it is of crucial importance to be able to model and analyze the complete functionality of the system within one single design environment. Therefore, we developed a computational model that integrates the speci cation of control and data ow by combining the notion of data ow graphs with event driven process activation.

CAMAC: a context-aware mandatory access control model
Mandatory access control models have traditionally been employed as a robust security mechanism in multilevel security environments such as military domains. In traditional mandatory models, the security classes associated with entities are context-insensitive. However, context-sensitivity of security classes and flexibility of access control mechanisms may be required especially in pervasive c...
متن کاملOptimal Locating and Sizing of Unified Power Quality Conditioner- phase Angle Control for Reactive Power Compensation in Radial Distribution Network with Wind Generation
In this article, a multi-objective planning is demonstrated for reactive power compensation in radial distribution networks with wind generation via unified power quality conditioner (UPQC). UPQC model, based on phase angle control (PAC), is used. In presented method, optimal locating of UPQC-PAC is done by simultaneous minimizing of objective functions such as: grid power loss, percentage of n...

متن کاملImprove dynamic performance of fixed speed wind turbines using unified power flow controller (UPFC) and fractional order controller (FOC)
Wind powers are very unstable in voltage fluctuations, especially in short circuit error and sharp and sudden voltage drops, which one of its main reasons is the use of induction generators in these power plants and thus need to reactive power and high magnetizing current. To improve the ride_through voltage from WECS in error conditions and damping the oscillations of the induction generator r...
