An Analysis Of The Effect Of Network Load And Topology On The Performance Of Concurrency Control Algorithm In Distributed Database Systems, Anoop Singhal, Amit P. Sheth, Ming T. Liu

Kno.e.sis Publications

Earlier studies in the performance analysis of concurrency control algorithms in distributed database systems (DDBS) have assumed that the message transmission time between any two nodes of a network is constant. Hence they disregard the effect of communication subnet related parameters such as network traffic, network topology, the capacity of transmission channels and the size of messages transmitted. In this paper an analytical model is used to estimate the delays in transmission channels for a DDBS in a long haul network. The analysis shows that the constant transmission time assumption cannot be justified in many cases and that response time …

An Exploration Of Nonbroadcast Television, Betty Conrad

Masters Theses & Specialist Projects

In this thesis, I have focused on the uses of video, or nonbroadcast television, as an instructional tool within three different contexts, i.e., the uses of video in medical, corporate and industrial settings.

Within this exploration, several problems have come to light. First, there is a need for higher education to train students in the field of nonbroadcast education, not only for broadcast students and new career opportunities, but also for students of business, medicine, art, and other career areas. As the uses of video become more widespread, so it becomes necessary to educate those who are likely to come …
