H-LOCAL RINGS
Title
H-LOCAL RINGS.
Creator
Omairi, Akeel, Klingler, Lee, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Mathematical Sciences
Abstract/Description
We say that a commutative ring R has the unique decomposition into ideals (UDI) property if, for any R-module which decomposes into a _nite direct sum of indecomposable ideals, this decomposition is unique up to the order and isomorphism class of the ideals. In a 2001 paper, Goeters and Olberding characterize the UDI property for Noetherian integral domains and in a 2011 paper Ay and Klingler obtain similar results for Noetherian reduced rings. We characterize the UDI property for Noetherian...

In a 2001 paper, Goeters and Olberding characterize the UDI property for Noetherian integral domains and in a 2011 paper Ay and Klingler obtain similar results for Noetherian reduced rings. We characterize the UDI property for Noetherian rings in general.

Delay characteristics of file transfer in token ring local area networks
Title
Delay characteristics of file transfer in token ring local area networks.
Creator
Horvath, Elizabeth Iren., Florida Atlantic University, Ilyas, Mohammad
Abstract/Description
The purpose of this thesis is to examine the delay characteristics of a token ring local area network with file transfers. The delay characteristics of the network are investigated by varying the file packet lengths, the variance in the length of the packets, and the utilization. The simulation model used has file packets which are assumed to be represented by a normal distribution. The results obtained indicate that at a designated utilization an increase in the variance of the packet's...

The delay characteristics of the network are investigated by varying the file packet lengths, the variance in the length of the packets, and the utilization. The simulation model used has file packets which are assumed to be represented by a normal distribution. The results obtained indicate that at a designated utilization an increase in the variance of the packet's length causes the delay to increase. The results can be used for capacity planning for networks whose primary task is file transfer.

Flow control in interconnected token ring local area networks
Title
Flow control in interconnected token ring local area networks.
Creator
Varughese, Sicely Babu., Florida Atlantic University, Ilyas, Mohammad, College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description
This thesis investigates some of the flow control issues in a system of Local Area Networks consisting of multiple token rings interconnected through bridges via a backbone ring. Flow control is realized by a window mechanism, i.e., a sender is permitted to transmit not more than a fixed number, W (the window size), of frames without having to wait for an acknowledgment. The solution is based on an existing approximation of the mean end-to-end delay in a stand-alone token ring LAN, which is...
Show moreThis thesis investigates some of the flow control issues in a system of Local Area Networks consisting of multiple token rings interconnected through bridges via a backbone ring. Flow control is realized by a window mechanism, i.e., a sender is permitted to transmit not more than a fixed number, W (the window size), of frames without having to wait for an acknowledgment. The solution is based on an existing approximation of the mean end-to-end delay in a stand-alone token ring LAN, which is extended by approximating the arrival rates at the bridges as a function of the throughput of each subnetwork and the probability that, the throughput is directed to the other subnetworks. The packet-lengths are assumed to be exponentially distributed. The performance of the system is evaluated by varying the window size.
