Item A longitudinal study of the diffusion of a computer-based administrative innovation within a university faculty network(Texas Tech University, 1997-12) Durrington, Vance A.Identifying predictors of computer use such as attitude, anxiety, and receptivity to change have been the primary area of interest in instmctional technology. Research relating to the diffusion of innovations in education has been based primarily on looking at these individual characteristics as predictors of use. This dissertation proposes to use social network analysis to study the diffusion of two computer-based administrative innovations within a university faculty network. Methodology issues concerning time of adoption and network nominations were examined as well as the relationship of time of adoption and the number of network nominations received, spatial proximity, and organizational unit proximity. Finally, the diffusion of the innovations was to be analyzed using the dual-classification and T/CM models.Item Performance evaluation of CSMA/CD local area network(Texas Tech University, 1986-05) Malik, Nasir A.Communications, the transfer and flow of information that is intelligible to people, is the key to development in science and technology. Scientific innovations have continuously improved the standard of living of individuals and the society as a whole. One of the greatest influences on the workplace and the society during the second half of the 20th century is the computer. Originally it was thought to be of use only for jobs in scientific research establishments. Soon it was applied to manipulation of business information with outstanding success. The computer technology explosion is not abating yet. New vistas into research, development and applications are opening, resulting in widespread use of computers.Item QoS parameters in IP and ATM and how IP maps onto ATM(Texas Tech University, 1999-05) Singh, GagandeepThis thesis describes the Quality of Service (QoS) parameters of the Electrical Engineering computer network at Texas Tech University for three different network configurations. The networks that have been modeled are the IP-Ethemet model, the IP over ATM model, and the LANE model. These networks have been modeled and simulated using the OPNET Modeler. The three networks have been simulated under high-load conditions of the workstations to investigate the performance conditions of the network. The three networks have been modeled in a top-down approach and each level of the network hierarchy has been described and discussed along with the figures showing the layout of the network. All three network models have been simulated and the results obtained have been shown through a series of graphs. The results obtained from these simulations have been compared to the statistics obtained from the switches in the actual network using SNMP. Conclusions and recommendations for further work have been discussed.
