The paper focuses on the problem of opinion classification related to web discussions and commentaries. It introduces various approaches known in this field. It also describes novelty methods, which have been designed for short conversational content processing with emphasis on dynamic analysis. This dynamic analysis is focused mainly on processing of negations and intensifiers within the opini...

Applications of X-ray image intensifiers in medical imaging, include the use of fluoroscopic projection images to generate three-dimensional tomographic reconstructions. Unfortunately, the inherent distortions on the acquired projections deteriorate the quality of the reconstructed tomograms. Distortion correction can be performed using algorithms that can be classified as global or local accor...

This paper presents the design of a real-time imaging system, with incorporated the correction of lens-distorted images. It may be used in medical applications (e.g. real-time X-ray image intensifiers), industrial robot vision products or consumer electronics. The system contains two different VLSI-circuits: a transformer and an interpolator. The transformer calculates an address that points to...

Pressure intensifiers have their utilization in hydraulic circuits, when there is a need for pressure multiplication some period of time. Using provides energy savings, cost reductions or smaller dimensioning. This article about intensifier based on rotary flow dividers. Its functioning evaluated by its pressure-multiplying efficiency. efficiency always calculated from values gained measurement...
