A novel concept of Minimal Set of Analytical Redundancy Relation (ARRs) and an efficient method for its calculation for application to system diagnosis is developed. The calculation of minimal set of ARRs can be performed by assigning a computation and/or precision cost to each ARR and the result will be a set of ARRs with minimal cost.

Novel scalable video coder for video streaming over wireless networks consisting in a multi layer scalable source coding, with high degree of scalability and robustness to packet loss.

This technology is a breakthrough in the auto calibrating techniques for multiple acoustic sensors.
