Polymerization Via a Metal Centered Catalyst from Nanocellulose
High-density polyethylene composites are now able to go beyond previously realized storage moduli at 6-7% v/v loading using cellulose nanocrystals (CNC)s as the filler material. Using a custom catalyst, polymerization is carried out directly from the surfaces of the CNCs in a heterogeneous (slurry) fashion. Mechanical testing showed that this...

PRIME: A Personalized Recommendation for Information VIsualization Methods via Extended matrix Completion
Information visualization is an important mode of human-computer interaction to acquire insights of complex datasets. However, a uniform visualization format may be inefficient to bring the insights to different users at different contexts due to the users' differences in knowledge, perception, and cognition capabilities. On the other hand, typical...

Variation Analysis and Visualization of Manufacturing Processes via Augmented Reality
In manufacturing processes and systems, many production and quality control decisions cannot be made in a timely manner due to the time delay for data collection, pre-processing and analysis. In this invention, we propose an online variation analysis and visualization method via augmented reality (AR) to operators. A regularized functional logistic...
