Trajectory prediction is widespread in mobile computing, and helps support wireless network operation, location-based services, and applications in pervasive computing. However, most prediction methods are based on very coarse geometric information s... Read More about Utilizing Massive Spatiotemporal Samples for Efficient and Accurate Trajectory Prediction.

A Fine-Grained Outcome-Based Learning Path Model (2013)
Journal Article
Yang, F., Li, F. W., & Lau, R. W. (2014). A Fine-Grained Outcome-Based Learning Path Model. IEEE Transactions on Systems, Man, and Cybernetics: Systems, 44(2), 235-245. https://doi.org/10.1109/tsmcc.2013.2263133

A learning path (or curriculum sequence) comprises steps for guiding a student to effectively build up knowledge and skills. Assessment is usually incorporated at each step for evaluating student learning progress. SCORM and IMS-LD have been establis... Read More about A Fine-Grained Outcome-Based Learning Path Model.

Laser-targeted ablation of the zebrafish embryonic ventricle: A novel model of cardiac injury and repair (2013)
Journal Article
Matrone, G., Taylor, J. M., Wilson, K. S., Baily, J., Love, G. D., Girkin, J. M., …Denvir, M. A. (2013). Laser-targeted ablation of the zebrafish embryonic ventricle: A novel model of cardiac injury and repair. International Journal of Cardiology, 168(4), 3913-3919. https://doi.org/10.1016/j.ijcard.2013.06.063

Background: While the adult zebrafish (Danio rerio) heart demonstrates a remarkable capacity for self-renewal following apical resection little is known about the response to injury in the embryonic heart. Methods: Injury to the beating zebrafish emb... Read More about Laser-targeted ablation of the zebrafish embryonic ventricle: A novel model of cardiac injury and repair.

Spectral representations of vertex transitive graphs, Archimedean solids and finite Coxeter groups (2013)
Journal Article
Ivrissimtzis, I., & Peyerimhoff, N. (2013). Spectral representations of vertex transitive graphs, Archimedean solids and finite Coxeter groups. Groups, Geometry, and Dynamics, 7(3), 591-615. https://doi.org/10.4171/ggd/199

In this article, we study eigenvalue functions of varying transitionprobability matrices on finite, vertex transitive graphs. We provethat the eigenvalue function of an eigenvalue of fixed highermultiplicity has a critical point if and only if the co...

The recent advancement of motion recognition using Microsoft Kinect stimulates many new ideas in motion capture and virtual reality applications. Utilizing a pattern recognition algorithm, Kinect can determine the positions of different body parts fr... Read More about Real-Time Posture Reconstruction for Microsoft Kinect.

Interactive Formation Control in Complex Environments (2013)
Journal Article
Henry, J., Shum, H. P., & Komura, T. (2014). Interactive Formation Control in Complex Environments. IEEE Transactions on Visualization and Computer Graphics, 20(2), 211-222. https://doi.org/10.1109/tvcg.2013.116

The degrees of freedom of a crowd is much higher than that provided by a standard user input device. Typically, crowd-control systems require multiple passes to design crowd movements by specifying waypoints, and then defining character trajectories...

Comparison of closed loop and sensorless adaptive optics in widefield optical microscopy (2013)
Journal Article
Bourgenot, C., Saunter, C., Love, G., & Girkin, J. (2013). Comparison of closed loop and sensorless adaptive optics in widefield optical microscopy. Journal of the European Optical Society-Rapid Publications, 8, Article 13027. https://doi.org/10.2971/jeos.2013.13027

We report on a closed loop widefield adaptive optics, optical microscopy system in which the feedback signal is provided by backscattered light from the sample acting as a guide star. The improvement in imaging performance is compared to an adaptive... Read More about Comparison of closed loop and sensorless adaptive optics in widefield optical microscopy.
