firewalls are not appropriate for ad hoc networks), IDS can help to monitor and analyze the traffic in UbiComp applications based on sensor networks. The analysis of audit data for the construction of intrusion detection models can be based on Data Mining algorithms which return frequent activity patterns. However, sensor networks pose new challenging requirements to DM methods, since the solut...

We introduce a new type of meshes called 5-6-7 meshes. For many mesh processing tasks, lowor high-valence vertices are undesirable. At the same time, it is not always possible to achieve complete vertex valence regularity, i.e., to only have valence-6 vertices. A 5-6-7 mesh is a closed triangle mesh where each vertex has valence 5, 6, or 7. An intriguing question is whether it is always possibl...

As eye-controlled interfaces becomes increasingly viable, there is a need to better understand fundamental human-machine interaction capabilities between a human and a computer via an eye tracking device. Prior research has explored the maximum rate of input from a human to a computer, such as key-entry rates in eye-typing tasks, but there has been little or no work to determine capabilities an...
