The design and operation of a cascade matrix electron flow amplifier based on an concentrator multiplier is considered. Unlike classical microchannel plates, the proposed can provide high density output current, which also allows it to be used as field cathode in vacuum microelectronics giga terahertz ranges. Keywords: Microchannel plate, secondary emission, screening, multiplier, cathode.

This master thesis deals with real-time algorithms and techniques for face detection and face tracking in videos. A new approach is presented where optical flow information is incorporated into the Viola-Jones face detection algorithm, allowing the algorithm to update the expected position of detected faces in the next frame. This continuity between video frames is not exploited by the original...
