Abstract The purpose of the paper is to present an original solution for conveying some liquids with help a rotating volumetric pump. pump can be equipped 1 4 specially processed profiled rotors and transport viscous fluids, pure or polyphase fluids. It was concluded that performance this machine, which also used as fan low-pressure compressor, superior other similar machines.

This paper contains the factorization of the polyphase matrix of finite impulse response perfect reconstruction filter banks into unimodular factors containing finite Jordan nilpotent structures and the associated transform matrices. An important contribution of the paper is the proposal of a systematic procedure for the construction of the transform matrices. The factorization is based on the ...

In this paper we investigate ‘real-time’ watermarking of singlesensor digital camera images (often called ‘raw’ images) and blind watermark detection in demosaicked images. We describe the software-only implementation of simple additive spread-spectrum embedding in the firmware of a digital camera. For blind watermark detection, we develop a scheme which adaptively combines the polyphase compon...
