The effects of bilateral electrolytic lesions of the "shell" subterritory of the nucleus accumbens in the rat were examined on 2 tasks known to be sensitive to hippocampal damage. Experiment 1 tested the effects of shell lesion on delayed non-matching-to-sample (DNMS) task in a T-maze. The maze was rotated 180 degrees after the end of acquisition.(More)
Stochastic automata networks (SANs) have been developed and used in the last 15 years as a modeling formalism for large systems that can be decomposed into loosely connected components. In this work, we concentrate on the not so much emphasized discrete-time SANs. First, we remodel and extend an SAN that arises in wireless communications. Second, for an SAN(More)
This paper introduces an analytical model of an access scheme for Wide Area Network (WAN) resources. The model is based on the Transmission Control Protocol (TCP)-modified Engset model of Heyman, Lakshman, and Neidhardt. The proposed model employs a Local Area Network (LAN) with arbitrary topology as the access network and is able to take into consideration(More)
In an attempt to increase data throughput, many modern data transmission protocols provide capabilities for aggregating transmitted data fragments into larger packets at the time of encapsulation in a particular OSI layer. The decision and ability to aggregate packets into a single frame can have significant impact on the performance of the communication(More)
