Ultrasonic inspection methods for defect detection and process control in roll-to-roll flexible electronics manufacturing
Roll-to-roll flexible electronics manufacturing technologies require new sensing and measurement capabilities for defect detection and process control. This body of work investigates the use of ultrasound, specifically Lamb and longitudinal waves, as a sensing modality and measurement technique for …

Roll pressure distribution in strip rolling.
… generated along the arc of contact between the rolls and workpiece during the rolling process has been a subject of interest to researchers for many years. Existing rolling theories make assumptions and include simplifications which are not often substantiated by direct measurement techniques in …

Rudder roll reduction for small ships
Roll motion on a ship can be very uncomfortable, and in the extreme, dangerous. It is possible to use the rudder to reduce roll motion as has been demonstrated by others on naval and coastguard vessels. For this study, five controllers were chosen and designed to implement a rudder roll reduction …

The roll of integrins in hematopoiesis
Hematopoietic stem cells (HSCs) hold great promise for the treatment of disease. The rare frequency at which HSCs occur in the bone marrow under homeostatic conditions is a limiting factor in both their study and clinical use. ex vivo expansion of these cells is therefore a necessary step to …
