Digital Signal Processing

Personal sound engineering and programming project by Jānis Kolosovskis with the following goals:

Practice learned C++ theoretical skills from online resources; Manually implement from first principles the algorithms learned from digital signal processing self-study to expand understanding of them; Practice use of JUCE library as the most common tool used for creating sound processing software Serve as a testing/analysis tool for future sound engineering project ideas by Jānis

Abstract The article introduces simple and effective algorithm for constant state detection in time series. The algorithm, based on sliding window of variable length, searches a sections of time series which have length more or equal than some given minimal length and have difference between maximal and minimal value in the section less or equal than some given value. It is shown that the computational complexity of aforementioned algorithm is O(N log N), where N is the length of time series.

The aim of this project is to provide an exploratory analysis of Domain Adaptation (DA) techniques in the context of PHM for Bearings fault prognosis, focusing on Health Index (HI) estimation and Remaining Useful Life (RUL) prediction. The adopted dataset is the PRONOSTIA/FEMTO-ST bearings dataset.
