  11. Showcasing MSIValue Added Activities • Minority programs • Outreach programs • Expanding opportunities for graduate and undergraduate education

  12. Summer Institute (1) • Establish a summer institute to enhance graduate student diversity • Four week summer program that includes faculty and students from HBCUs • Increase chances of success for students from HBCUs at Purdue’s graduate program

  13. Summer Institute (2) • Costs are shared between Purdue and industrial sponsors • Funds are at least $10K/year • Program is limited to 10 students and one faculty mentor from each University • Start in Summer 2000

  14. Fisk University - Partnership in Research and Education • Existing joint funding with Fisk from EPRI/DoD • Plans for enhancing the resources at Fisk • Frequent visits and exchanges • Plans for new proposals

  15. MSI Overview • Mission: Research, education, and outreach in the field of Multimedia Computing • Through a unique new project in integrated quality management across various system layers

  16. Focus • The use of relevant research in Multimedia with an emphasis on QoS management for the experimental infrastructure consisting of the following technologies • Networks • Security • Databases • Compression • Storage management

  24. Electron Micrograph of a Rumen Protozoa with Attached Bacteria. BACTERIA: Primary bacteria: Degrade the actual constituents of the diet (Cellulolytic and amylolytic bacteria) Secondary bacteria : Use as their substrate the end products of the primary bacteria e.g. Lactate -utilizing propionate bacteria, methanogenic bacteria PROTOZOA: - Utilize starch granules and other readily digestible materials - Presence in rumen liquor sample indicates normal intra-rumen conditions - Form a reservoir of microbial proteins at times of intermittent supply - Curb high rates of starch degradation - Utilize starch granules and other readily digestible materials Omasum Abomasum Reticulum Esophagus Protozoa Rumen Stomach Digestive System Small Intestine Salivary Glands Large Intestine Multimedia Browsing Graph Exit The Ruminant Digestive System Four compartment stomach that: - utilizes complex carbohydrates such as cellulose - utilizes non-protein nitrogen sources - utilizes feeds of no nutritive value for humans Rumen The rumen, the first compartment of the ruminant stomach, is essentially non-functional at birth but develops rapidly when calves are given solid feeds such as hay and grain. MICROBIAL FERMENTATION: Microbial fermentation is an anaerobic process Microbes live in a symbiotic existence with the host (e.g. Cow) Microbes do not have complete TCA cycle, volatile fatty acids (VFA) are byproducts of their anaerobic metabolism, which the animal can use B vitamins and vitamin K are produced by microbes

  25. Planned Activities • Develop a common infrastructure to integrate key technologies. • Experiment with prototypes, tools, and algorithms to support distributed multimedia applications. • Leverage existing projects and relationships to expand the scope of research. • Disseminate significant results. • Empirical comparisons with relevant commercial systems.
