— A powerful path computation element is a must for the next-generation IP-over-Optical networks to support on-demand service provisioning crossing layers. The main purpose of path computation in multi-layer networks (MLN) is to enable traffic engineering (TE) under a multitude of constraints. A common objective of such traffic engineering is to minimize(More)
Sensing of human motion is very important for human-computer interactive applications such as virtual reality, gesture recognition, and communication. A vision system is suitable for human-computer interaction since this involves passive sensing and the system can estimate the motion of the user without any discomfort for the user. In this paper, we propose(More)

A vision system is suitable for human–computer interaction since this involves passive sensing and the system can estimate the motion of the user without any discomfort for the user.

—Today's ICT system necessarily involves multiple system domains complying with different management models. Integration of domain-specific management models is required to achieve, for example, agile fault localization in a huge ICT system, but this has not been efficiently achieved due to the difficulty in bridging multiple management models. To address(More)
