Show moreHigh temperature, short time pasteurization was used to evaluate a computer-based system for controlling the pasteurization process, acquiring data, and monitoring records. Software was used for the control of hot water temperature, flow rate through the centrifugal timing pump, and diversion of under-processed product. Three types of control strategies were conducted: single loop, cascade, and multivariable. The single loop control strategy showed the most rapid responses to temperature changes, but the temperature response curve was slowest to return to its set point. The cascade control strategy showed slower recoveries to temperature changes, but the temperature response curve was smoother. The multivariable control strategy responded slightly faster than the cascade control strategy, and the temperature response curve was slightly smoother than the cascade control strategy. The multivariable control strategy was able to control the flow diversion valve by the use of a lethality controller. The data acquisition system, used to monitor the data obtained from the high temperature, short-time pasteurization system, was within +/- 0.1 degrees C of the temperature recorded by the safety thermal limit recorder. Reliability was determined by examining the changes in the position of the flow diversion valve to identify process deviations and by comparing the changes to the event marker on circular charts. The data acquisition system was an effective alternative for monitoring the completeness of data.

Show moreThis IPRO is being run as part of the IIT Information Retrieval Lab. This is one of the only labs in the country dedciated to next generation search engines. Team members will learn all about search engines and will help build one different from existing search engines. Current web search engines only search unstructured data (web documents). A lot of data is available that is structured (weather, census, sports, etc.). A search engine that could search both structured data and text would be able to answer questions such as "show me the top three restaurants in Chicago" without simply looking for the word "three." Previous IPRO teams have been building a Java-based metasearch engine. Numerous issues have arisen. How do we identify which data source will be best for the query? What is the best user interface for the system? For Spring 2002, the team will extend the search engine to include more sources. The team could really use the talents of non-computer science students to help test the system and improve the user interface.
