Abstract: An apparatus for processing compacted biomass is provided which include a conveying system forwarding compacted biomass in a controlled manner in a mainly horizontal direction, and first and second rotatable rollers positioned downstream of the conveying system with their axes of rotation generally horizontal and parallel. The first roller is positioned horizontally closer to the conveying system than the second roller. The first and second rollers are rotated in opposite directions with different peripheral speeds and the rollers are provided with teeth-like elements projecting from the outer surfaces to engage the compacted biomass material and to pass the material through a gap formed between the two rollers. The peripheral speed of the second roller is higher than the peripheral speed of the first roller, whereby the material to be processed is fed into the gap in a controlled manner and subjected to a stretching and loosening action in the gap with low energy consumption and high reliability.

Abstract: The present invention provides for a method for maximum likelihood estimation of bearings. This method of the present invention utilizes a novel maximum likelihood algorithm which can be employed to process one or two dimensional array data. The method is applicable to radar and sonar direction-of-arrival estimation problems.

Abstract: The maximum likelihood function can be simplified by exploiting the symmetry in the equations. This new representation leads to a very significant decrease in the computational load for bearing estimation and spectral analysis applications.
