Design Patterns for the Implementation of Constraints on JavaBeans
نویسندگان
چکیده
Although constraints are useful to express semantic restrictions on object structures, Java provides little support for their implementation and evaluation. We argue that constraints should be specified explicitly, and propose a set of design patterns for the representation of constraints on JavaBeans. Object-oriented reflection is used to evaluate these constraints at run-time. We show how this technology can be used to support data and knowledge acquisition, and system evaluation.

Checking OCL Constraints in Distributed Systems using J2EE/EJB
We present a pragmatic approach using formal methods to increase the quality of distributed component based systems: Based on UML class diagrams annotated with OCL constraints, code for runtime checking of components in J2EE/EJB is automatically generated. Thus, a UML–model for a component can be used in a black–box test for the component. Further we introduce different design patterns for EJBs...

In this paper, a model is proposed based on the different levels of social restrictions for the COVID-19 spread restraint in Iran. Also, a Genetic Algorithm (GA) identifies parameters of model using reported main data from the Iranian Ministry of Health and simulated data based on proposed model. Whereas Model Predictive Control (MPC) is a popular method which has been widely used in process ...

This paper presents design and implementation of Model Based Predictive Controller (MPC) for a novel Bi-Rotor Moving Mass Controlled (MMC) Unmanned Aerial Vehicle (UAV). Due to the strict constrained control inputs in this type of UAV, it is necessary to take into account the constrained controller design and un-constrained control methods are not applicable. MPC controller which is designed ba...
متن کاملDesign and Implementation of a High-Precision Position Controller for Permanent Magnet Synchronous Motor Based on a New Gain Scheduling Approach
The direct drive permanent magnet synchronous motor (DD-PMSM) is a suitable choice for high-precision position control applications. Among various control methods of this motor, the vector control approaches especially the field oriented control has a high-performance in the industrial drives. In this method, the components of stator current are controlled independently and as a result, the tor...
