  [PDF]
• Radosław Szreder, Przemysław Sul, Krzysztof Pachowicz: The requirement of galvanic isolation of current and voltage measuring sensors for three-phase mains grid causes a number of problems related to sampling synchronism, data transmission and sensor supply. Article describes the unique distribution system of power and synchronizing signal for galvanically isolated sensors - transducers sampling currents and voltage in the three-phase power network. Synchronization of sampling rate is mandatory due to the accuracy of the of phase shifts angles measurement between voltages or currents in grid and consequently the calculations of power, energy, synchrophazors and RMS value

• Agnieszka Duraj, Łukasz Chomątek: Detection of outliers in data streams using grouping methods
  [PDF]
• Kamila Jadczak, Rafał Białek, Michał Wiśnios, Marek Kuchta: Efficient processing of data streams usually requires their initial processing, including on the removal of anomalies caused by, for example, measuring errors. Such errors may result in misinterpretation of the phenomena being analyzed .The literature describes several methods for detecting exceptions in data streams. Each of them requires proper selection of operating parameters. In addition, the effectiveness of methods may vary depending on the data set being analyzed. The article describes current methods for detecting exceptions in data streams and analyzed their operation on gas consumption data.
