Undergraduate Research Participation in Electrical Engineering

The Electrical Engineering Department at the University of Maine will offer ten undergraduate students the opportunity to participate in research. The available research projects include: 1. Microwave Acoustic solid State Sensors, 2. Robotics, Computer Vision and Neural Processing, 3. Communications Devices and Applications, 4. Motion Control, 5. Microprocessing/Instrumentation Applications, 6. Macroscopic and Microscopic Characterization of Metallic Films, and 7. Power Systems Applications. in addition to extensive University of Maine facilities, the students will also have access to facilities at nearby industries such as Bangor Hydro Electric Power and Central Maine Power Companies, James River, Champion and Scott paper Companies, Digital Equipment Corporation and National Semiconductor during the conduct of their research experience

GOALI/IUCP: Prediction of Wood Pulp K-Number with Neural Networks

Lignin holds wood fibers together, and must be removed to produce high strength pulp for kraft paper. The Kappa- or K-number indicates the degree of lignin removal by a pulping process, and is probably the key variable for measuring quality in this process. A difficulty is that it is an off-line measurement. More importantly, there is usually a four hour process delay between when raw materials enter a pulping digester and when the K-number is measured. This makes modeling and control difficult. This Grant Opportunity for Academic Liaison with Industry project uses neural network models to predict K-number as a function of a number of more readily available process parameters. This is a first step in improving the control and responsiveness of this process to changes in chip feed stock. The research team from the University of Maine and S.D. Warren Company will develop characterization and prediction models using data from an operating plant, and compare their long term predicative capability when integrated into digester operations. Throughout, seminar and workshops are part of the technology transfer and model improvement. The impact of this research will be more uniform quality of pulp, even with variable feed stock, and more uniform quality in subsequent bleaching and papermaking processes
