PVA

Proceedings of the seventh ACM SIGKDD international conference on Knowledge discovery and data mining, 2001
In this paper, we present PVA, an adaptive personal view information agent system to track, learn and manage, user's interests in Internet documents. When user's interests change, PVA, in not only the contents, but also in the structure of user profile, is modified to adapt to the changes. Experimental results show that modulating the structure of user

Nanohybrid PVA/ZrO2 and PVA/Al2O3 electrospun mats

Chemical Engineering Journal, 2008
Abstract Fibrous poly(vinyl alcohol)/zirconia and poly(vinyl alcohol)/alumina nanohybrids were obtained by electrospinning technique, the applied voltage ranging between 12 and 16 kV. The actual nanofiller content ranged between 2 and 9 wt%. Electrospun nanohybrids consisted of uniform fibers free of defects. The average fiber diameter was around 600
