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.
As the Internet of Things evolves, many devices that were not previously considered suitable for this trend can now be used as a part of smart interconnected systems. This paper describes the process of adapting a Cis...

The paper presents preliminary results for on-line measurement method of isopropanol concentration in the ultrasonic nebulization process using BW-Tek compact UV/Vis spectrophotometer. The experimental setup with nebulization vessel was constructed with a probe for on-line measurements. The tests were performed using a standard mixture of isopropanol and water with the volume isopropanol concentration in the range 19% to 83%. The results of on-line spectrophotometric method were verified using stationary spectrophotometer and a gas chromatography method. Linear calibration for the obtained data was performed and measurement uncertainties for the tested method were evaluated as confidence intervals.
We formulate fractional difference equations of Riemann-Liouville and Caputo type in a functional analytical framework. Main results are existence of solutions on Hilbert space-valued weighted sequence spaces and a co...
