This paper presents an active database discrimination network algorithm called Gator, and its implementation in a modiied version of the Ariel active DBMS. Gator is a generalization of the widely known Rete and TREAT algorithms. Gator pattern matching is explained, and it is shown how a discrimination network can speed up condition testing for multi-table(More)
This paper presents a new active database discrimination network algorithm called Gator, and its implementation in a modiied version of the Ariel active DBMS. Gator is a generalization of the widely known Rete and TREAT algorithms, and is designed as a target for a discrimination network optimizer. Ariel now has an optimizer that can choose an eecient Gator(More)
Mobile ad-hoc network (MANET) is a dynamically reconfigurable wireless network without any centralized administration or infrastructure. Multicasting is the transmission of datagram's to a group of nodes identified by a single destination address. Multicasting can efficiently support a variety of applications and services. Most of existing multicast routing(More)
We recently showed that deep brain stimulation (DBS) in the bed nucleus of the stria terminalis (BST) reduces obsessions, compulsions and associated anxiety in patients suffering from severe, treatment-refractory obsessive-compulsive disorder. Here, we investigated the anxiolytic effects of electrical BST stimulation in a rat model of conditioned anxiety,(More)
This paper brieey presents a new discrimination network algorithm called Gator that is a generalization of the widely known Rete and TREAT algorithms. Gator is designed as a target for a discrimination network optimizer. Several strategies for optimizing Gator networks were implemented, and then tested and compared using randomly generated simulated rule(More)
