The acceleration of Magnetic Resonance Imaging techniques is still very important in current development. The application of Compressed Sensing for medical data accelerates the acquisition time and satisfies the image quality. The method relies on the sparsity condition and requires only the most important data instead of acquiring all data according to the Nyquist-Shannon sampling theorem. The paper shows the application of different image quality parameters in order to compare the original method of Compressed Sensing for phantom and medical data.

In this paper the problem of detection of impulsive disturbances in archive audio signals is considered. It is shown that semi-causal/noncausal solutions based on joint evaluation of signal prediction errors and leave-one-out signal interpolation errors, allow one to noticeably improve detection results compared to the prediction-only based solutions. The proposed approaches are evaluated on a set of clean audio signals contaminated with real click waveforms extracted from silent parts of old gramophone recordings.

The paper presents the application of the linearizing control technique for stabilization of the isopropanol concentration in the ultrasonic nebulization process. The isopropanol concentration has to be kept constant to make the nebulization process more efficient. This is achieved by manipulating the inlet flow rate of a fresh isopropanol-water mixture. Because the content of the vessel is not well-mixed, it was shown that by measuring only the isopropanol concentration at the bottom of the vessel, the control system performance could be improved by the optimal selection of controller parameters. Moreover, the simulation results have show n that the closed-loop system was stable and exhibited similar behavior, even if the nebulization rate was not know precisely.
