The article presents the methods of determination and analysis of the continuance of harmonics in the supply current of a modern subway vehicle with an asynchronous converter power. Knowledge of the harmonic content of the supply current is a very important part of the study, allowing the vehicle to operate. In order to determine the harmonic voltages and currents, a computer model of the test vehicle and the power supply and subway substations was created. The simulation was created using the SimPowerSystem library, which is part of the Matlab program. The calculation results were compared with the measurement.

Analiza obrazów mikroskopowych odgrywa obecnie dominującą rolę w badaniach nad strukturą mózgu. Wgląd w strukturalną plastyczność synaptyczną może być kluczem do zrozumienia podstaw wielu zaburzeń neurodegeneracyjnych. Prawie w każdym eksperymencie niezbędna jest ilościowa analiza obrazów tkanki mózgowej, wymagająca często wyspecjalizowanego oprogramowania komputerowego ze względu na złożoność struktur analizowanych obrazów. W niniejszym tekście dokonamy przeglądu najważniejszych problemów towarzyszących analizie obrazów zebranych mikroskopem konfokalnym. Każdy z tych problemów wymaga zastosowania dedykowanych algorytmów.

The analysis of confocal microscopy images has started to play a significant role in the brain structure analysis. An insight into structural synaptic plasticity may be the key to elucidate the molecular basis of many neurodegenerative disorders. Almost every experiment demands a quantitative analysis of brain tissue images, which requires specialized software able to cope with the structural complexity of the data. In the following text we will review common issues arising while performing the confocal image analysis and dedicated algorithms designed to overcome those problems.
