This paper discusses challenges in enabling teleoperation over the Internet for the specific case of real systems which exhibit fast dynamics. A distributed client-server architecture is proposed to provide the necessary level of interactivity for supervision and tuning, without compromising the essential control tasks. Enabling features include realtime simulation and augmented-reality visuali...

Geometry compression is an effective way to distribute high-volume geometry data within limited bandwidth and storage capacity. In this paper, a new time-varying 3D geometry compression method based on 4D lifted wavelet transform is presented. In this hybrid approach, geometric information and animation are compressed based volume grid values. Isosurfaces are reconstructed from decompressed gri...

Surgical treatment of intraarticular calcaneal fractures is often associated with postoperative wound problems. Soft tissue necrosis, bone loss and uncontrollable infection are a challenge for the surgeon and amputation may in some cases be the ultimate solution. A free flap can be very helpful to cover a significant soft tissue defect and help in fighting the infection. However, the free flap ...

Monte Carlo codes are utilized for accurate dose calculations in proton radiation therapy research. While they are superior in accuracy to commonly used analytical dose calculations, they require significantly longer computation times. The aim of this work is to characterize a Monte Carlo track-repeating algorithm to increase computation speed without compromising dosimetric accuracy. The track...

In this paper we address the problem of subsumption checking for subscriptions in pub/sub systems. We develop a novel approach based on negative space representation for subsumption checking and provide efficient algorithms for subscription forwarding in a dynamic pub/sub environment. We then provide heuristics for approximate subsumption checking that greatly enhance the performance without co...

This paper addresses the Focus+Context issues involved in navigating very large graphs in 3D Euclidean space. The main aim of the approach presented in this material is to preserve and perhaps enhance the user mental map during the transition phase from one focus object to the other. This approach, NavAssist, accomplishes this task by filling the users view port with the maximum amount of infor...
