In the second section we look at the use of CD-ROM in a VoD server and discuss the problem of scheduling multiple request streams and buffer management in this scenario.
We also propose an adaptive main-memory hosted cache that receives caching hints from the application to reduce the latency when the user moves from one node of the hyper graph to another. We discuss prefetch buffer design and seek time characteristics in the context of the analysis of these traces.
Since these multimedia applications are highly interactive in nature, we take a pragmatic approach, and have made a detailed study of the multimedia application behavior in terms of the I/O request patterns generated to the CD-ROM subsystem by tracing these patterns. In the first section of this paper we look at issues related to the single- user desktop environment. With CD-ROM capacities up to 3 GB being available in the near future, they will form an integral part of Video on Demand (VoD) servers to store full-length movies and multimedia. Sampath-Kumar, SrihariĬD-ROMs have proliferated as a distribution media for desktop machines for a large variety of multimedia applications (targeted for a single-user environment) like encyclopedias, magazines and games. PMID:18068940ĭesign issues and caching strategies for CD-ROM-based multimedia storage Practice Implications Our preliminary results illustrate that healthcare professionals and researchers may use interactive multimedia for improving exercise behavior and related outcomes with pregnant and postpartum women. Conclusion The multimedia CD-ROM delivering information about exercise motivation, guidelines, and prescription was effective in improving exercise self-efficacy and knowledge. Results In analyses of covariance, compared with the control group, the experimental group had significant increases in self-efficacy and knowledge. Main outcomes were exercise self-efficacy and knowledge. Methods Pregnant and postpartum women, who were randomly assigned to either the experimental group (PregXerciseâ„¢ CD-ROM) or the control group ( CD-ROM with neutral content), navigated through the CD-ROM for 1 hour. Objective To meet the need for an interactive product on exercise during pregnancy and postpartum, we developed and evaluated a personally-tailored multimedia CD-ROM. Cook, Brian Downs, Danielle Symons Weis, Carol Ann Nigg, Claudio Cruz, Amelia Individuals who are interested in improving the effectiveness of their environmental training program as well as individuals who are interested in understanding the strengths of multimedia CD-ROM based training will find this session useful and informative.ĭevelopment and Evaluation of a Multimedia CD-ROM for Exercise During Pregnancy and Postpartum This session will also describe the instructional design strategy underlying this approach to training and will present some preliminary findings with respect to the effectiveness of this approach. The objective of the course is to make workers aware of their roles and responsibilities with respect to their impact on the environment. This session will demonstrate a multimedia CD-ROM based course on Environmental Awareness designed for workers in the electrical utilities industry. to explore the use of CD-ROM based multimedia as a means of delivering individualized instruction in an effective and timely manner. Time and scheduling constraints tend to limit the effectiveness of traditional approaches to training. While recognizing the problem of ineffective methods of teaching in Nigeria's educational system, the .Įnvironmental awareness - An interactive multimedia CD-ROMĮnergy Technology Data Exchange (ETDEWEB)Īs corporations move to new and innovative ways of structuring high-performance work teams, effective training is being recognized as a key to insuring success. This paper examines the potentials of utilizing Compact Disk Read Only Memory ( CD-ROM) and the multimedia projector as complimentary educational technology for teaching music in colleges of education in Nigeria.
